Communications industry are UPS (uninterruptible power supply | voltage regulator) the application of large,laptop battery ,as the core of the whole power supply room, UPS is a problem first and foremost reliability, then it is safe, green, energy-saving, if set aside to talk about green and energy security are meaningless.

A standard power supply system of the engine room including transformers, diesel generators, low-voltage distribution cabinets, DC Switching Power Supply, UPS, fujitsu laptop battery, the most important are the power supply unit UPS. Computers are UPS load, and UPS-to-city electric power grid, it is a load.

Harmonic pollution caused severe damage to power

Ideal UPS should be on the grid are presented purely resistive, that is to say, UPS power factor of 1 are the best, so its power grid, there is no pollution. However, the reality is, we generally use UPS for 50Hz low-frequency silicon-controlled rectifier, hp f1739a, for the city of electricity produced many a harmonic feedback pollution. Before all users are governance before the harmonic pollution problem, as we, like the discharge of sewage treatment plant.

Harmonic great harm, it does not Work, but occupied by a large number of grid KVA (transformer unit) resources. Harmonic voltage distortion resulting in increased harmonic increases made to match UPS and generators produce a lot of questions. Usually require power generators are UPS 2 ~ 3 times,omnibook xe battery, otherwise it will be difficult to start the UPS, and even lead to the user switches often inexplicably tripping.

Harmonic components are extremely complex, harmonic power factor improve governance is far from being that simple. Lot of people think you add some nice compensation capacitor,hp f2024b , hp f2024a, but only as a linear motor as the load in terms of. For UPS rectifier type nonlinear load, a simple capacitor compensation will prove counterproductive, may lead to further distortion.

IGBT is superior to the traditional pulse modulator

Currently on the market about UPS harmonic pollution treatment modalities, there are: 6-pulse rectifier + input filter; 12-pulse rectifier; 12-pulse rectifier + input filter; active filter. These methods have a common disadvantage, that is the first pollution control. UPS are used because of thyristor rectifier structure, omnibook xe3 battery, will inevitably result in harmonic pollution, then users are forced to spend large sums of money to govern harmonic pollution. If UPS does not produce or produce very little harmonic pollution, and that users need to spend money to govern it. Eaton Powerware offers full-line UPS using IGBT (insulated gate-type power tubes) rectifier way up from the fundamental current harmonic pollution curbed its down to 3%. For the field of UPS, this structure is the ultimate management of harmonic solutions.

Now a lot of users are used to rectifier pulses to evaluate the quality of UPS, they will ask to IGBT rectifier is the number of pulses. Say easy, IGBT rectifier using pulse width modulation manner, IGBT carrier frequency to reach 8300Hz, pulse 8300 can be referred to as the rectifier, but this is certainly better than a lot of 12-pulse rectifier. If the oscilloscope to observe the UPS input voltage and current waveforms, will see the waveform is very pure sine wave, the power grid without any feedback from pollution,hp 346970-001 , hp hstnn-db02 , it is the active harmonic governance.

IGBT power components as a sophisticated power electronic components, nearly 20 years of history, hp hstnn-ub02 , hp dp390a, all of the current global manufacturers have put it as inverter components. Eaton Powerware Corporation from 2000 it used to start rectifier, now from 8 to 1100 volt-ampere volt-ampere of the UPS used IGBT rectifier and IGBT inverter.

Based on the performance of our country is different from the UPS is divided into 3 categories, like clothing, as there is a materials and secondary commodities. UPS is the best use of IGBT Rectifier UPS, its input voltage range to ± 25% or more,hp pp2100 , presario r3000 battery, input power factor at 0.95 to more than the total input current harmonic distortion is less than 5%. Powerware online UPS all belong to the ranks of the best grade.

UPS effectively help users to reduce power consumption

Today's computers and servers 10 years ago are very different, very high power density blade servers have been very popular, presario x6000 battery,pavilion zv5000 battery server commonly used dual power supply. And UPS power supply system is also commonly used 1 +1 redundant parallel, therefore, UPS brought a single load are very low. In this way, we can see that UPS full load efficiency of users there is no practical significance, because in reality no one will use UPS full load to 50% can be pretty good. Therefore UPS light load efficiency when the machine instead of a more meaningful for everyone. Powerware UPS at full load can reach 95% of the machine efficiency, 50% at a time when the load can still reach 95%, and even at 25% load efficiency when the machine is still up to 94%.

Powerware UPS up to 95% of the whole premise of efficiency are already guaranteed the UPS input power factor is greater than 0.99,pavilion zv6000 battery,pavilion dv1000 battery enter the harmonic distortion of less than 3%, and when only 50 percent load, it can reach 95%. And similar products can only be achieved if the same indicators, but also need to add a large number of options such as input filters, 12-pulse rectifiers and so on, each additional option will further reduce the overall efficiency of UPS. Therefore, the 12-pulse rectifier, the efficiency will be reduced 2%, active power filter system efficiency would reduce the 4%, so much in the actual measurement of the machine 12 pulses UPS efficiency of less than 88%.

UPS in the procurement of a lot of people only concerned about the price of the UPS itself, pf723a , hp 367759-001,hp ev087aa not knowing the use of UPS cost is much higher than the value of its own.

For example, one of the UPS Units 200KVA its purchase price in about 50 million, but it was a year of electricity 200 × 24 × 365 = 1752000 yuan, or 1.75 million yuan, UPS is the annual electricity 3 times its price. If we make a comparison, the 9395 Series 1 Units Powerware 200KVA UPS machine efficiency of 95 percent, pm579a , pavilion dv4000 battery, while a 12-pulse rectifier efficiency is only about 88 percent. At the 10-year life cycle of the UPS, the Powerware UPS to save electricity by 200 × 0.07 × 24 × 365 × 10 = 122 million. Power will be distributed by the form of heat, so the user had to pay for many electricity users HVAC, and UPS for users unknowingly saved more than 200 worth of electricity.

At present, some UPS manufacturers to adopt energy-saving bypass mode, which bypass the principle is that if at a certain voltage range, UPS power supply directly through the bypass, when the UPS is highly efficient, but at the expense of efficient load safety price. Since this time the UPS rectifier inverter does not power supply, power grids in a variety of transient interference with direct load,pavilion dv2000 battery , hp hstnn-lb31,UPS does not isolate the role. And when the city when the electric power, UPS switch is interrupted. Only when in-line double conversion UPS mode, it can provide a full range of power supply load protection. If the load is based on the cost of security in exchange for high-performance, I think nobody will be recognized.

Have a little reminder, that is, a lot of users at UPS false start did not load after the test, because then they can not find the fake high-power load. Powerware UPS can provide its own Analog false load testing, we call it EASY LOAD patented technology, UPS internal can produce a full load test. Similarly,hp f4486b ,hp cgr-b1870ae, we can make full battery discharge test. So, this way we can test out the system all the aspect, because the elimination of UPS internal wiring is not strong, loose, such as potential pitfalls.

UPS because once the formal run into inconvenient downtime after the overhaul. Powerware this test function can be found hidden danger for users,hp pavilion dv8000 battery , while saving more than 50,000 yuan false load leasing, the cost of electricity and cable connection.

Nokia users ask: Why not in the end product

Recently, the Beijing lawyer Zhao Xiaoliang to Nokia reported on the court, he requested the court orders the defendant to deliver high-performance low-power consumption Nokia cell phone batteries, cell phone battery and the old 190 per block of Price and Recycling for harmless treatment, while at Mobile instructions clearly marked cases containing harmful substances.

Zhao Xiaoliang yesterday morning told reporters that the case has entered the appraisal stage, "I have to apply to the relevant departments to identify themselves out of the 5,000 identified costs, that is, in order to find out what pollutants battery!" According to Zhao Xiaoliang organize information, "cell phone and hp laptop battery containing lead, mercury, cadmium and other toxic and harmful substances. cell phone battery will be directly contaminated soil and water resources, can be a battery contained cadmium pollution standards three Olympic swimming pools of water, according to conservative projections, each year about 2.6 100 million cell phone batteries have been eliminated and will pollute the near 800 million swimming pool. "

Zhao Xiaoliang introduction, in many countries, mobile phone manufacturers are recycling must bear the responsibility, "Why Strict implementation of Nokia abroad Electronics Recycling litter the relevant laws for their own products pay pollution,hp f4098a , hp f4809a , while in our country not to do so? Cell phone in the end for our health hazards caused by how much? I must fight this lawsuit in the end! "

Consumers to stir up troubles: replacement cell phone easy to difficult to deal with the old mobile phone

At present, the case of winning or losing no conclusion has been drawn. But "for a cell phone, the hp 367759-001,hp VGP-BPS5 did not throw place" or who is in charge of these batteries, it is almost so that each person who sympathizes with the matter.

Li Qiang at an online mobile phone shops, at his old customers, many are using one for two months on a cell phone, he told Morning News reporter, "a work in Huangpu district relatively advanced white-collar extreme, two weeks to find him once I bought a new mobile phone 2. Youth is the pursuit of fashion,hp f4812a ,compaq 319411-001, modeling good or as long as the cell phone with new features, they wanted a change, and sometimes buy one to spend one month on income. "

Yang Jie 3 near the public has changed in three mobile phone, "because of job reasons, the original mobile phone book always seemed old too, or is the lack of telephone recording functions, and gradually have been eliminated me. But the old models machines do not give it to send out, throw it away feel pity,presario 2100 battery, it has been placed, I do not know when they could swap deal! "random journalist of 20 regular replacement of Youth to investigate the cell phone, most of them said that if there is formal channels Recycling eliminated from the cell phone and battery, can be considered free to donate their obsolete mobile phone.

According to Shanghai Mobile, a person in charge to the Morning News reporter Tou Lou, according to statistics of relevant departments of the company, Shanghai is currently updated annually about 3.2 million mobile phones (including PHS),presario 2500 battery,the city's mobile phone users on average one and a half years to 2 years replacement of a mobile phone, the replacement of one of fashion mobile phone owners are becoming more and more faster speed. "According to these figures to each mobile phone is equipped with two batteries, the city eliminated the annual quantity of mobile phone batteries are extremely shocking. However, at present, the city has not yet set up a fairly standard recovery channels."

The reporter learned that apart from recycling channels have not been perfect,presario nx9010 battery, the current big cell phone manufacturers cell phone after the sale, have no corresponding or old cell phone battery recycling system, it is indeed a matter for consumers to stir up troubles.

Recycling enterprise helplessness: U.S. production lines "food"

On the one hand, consumers do not know where to throw, on the other hand, determined to deal with some of the old cell phone presario nx9000 battery companies have "enough." New Jinqiao Industrial Waste Management Ltd. as an example, because of the imperfect system of social recovery, the production line is still only done 20% to start.

The company's general manager, Mr Wong Sun-frankly, "Recycling is the largest aspect of the problem." On society's scrap electronic products are more scattered, one by one pick-up cost too much, tell people to go big all the way to send them is not realistic. If the production line in order to start a small number of waste products, the cost is too high too little profit. Assistant General Manager Julian introduce legislation "to deal with lithium hp f2299a , hp f3172a recycling, there is no technical problem, the crux of the channels or Recycling is not very smooth."

In addition, if people put waste to the individual mobile phone and battery recycling, they factory-style handle on the environment may cause great harm. "Their solution is to soil: the use of fire burning with acid, alkali corrosion. Caused substantial burning gas into the atmosphere,hp f2019 , hp f2019a, and a good deal of electronic garbage were after the indiscriminate discharge of acid-base, which has resulted in some areas of our country suffered. indigenous treatment, but also cause great waste, in fact received the 'Product' is only a tiny percentage of precious metals, much of this could be re-used materials, have become the scourge of pollution of the environment. "

Pudong New Area Environmental Protection Bureau Health Department amenity Priscilla Wong accepted Morning News reporters Cai Fangshi and Ye Biaoshi, China's environmental protection laws and regulations are continuously improved, the mobile phone and hp f2019b , omnibook 6000 battery in a similar way to electronic waste legislation is the direction. However, due to regulations before the Department has the necessary environmental protection for the public to the dangers of electronic trash has a deeper understanding.

Utilization of waste battery technology and its facilities
Technical points:

At present, a battery for scrap, because of the lack of an effective, economic, and the application of recycling technology for centralized country does not encourage the collection, in order to reduce the secondary pollution.

In fact, a battery waste contains a lot of useful material, our country is a battery production and consumption of large countries, the annual production in this area is necessary to consume 250,000 tons of zinc, 240,000 tons of manganese, 04,500 tons of copper, 0.060 tons of mercury; primary metal resources will reduce poverty, and to carry out the recycling of used latitude c610 will help conserve resources, be conducive to improving the environment.

The present invention patent is to scrap a latitude c640 , through the closed mechanical processing, the application of physical methods, the full recovery of used batteries in the copper, zinc and other substances; mercury vacuum steam, condensate recovery method to the mercury pollution of the environment to extract and Recycling; the remaining material to add trace elements, processing made "methane fermentation enhancers.

" The whole compact process equipment, the implementation of intelligent management and operation of treatment process makes the "three wastes" discharge to maximize the dell 1691p will last all the comprehensive utilization of waste, reached the safety, environmental protection, economic and efficient utilization of resources. Makes the treatment of waste batteries is no longer a loss-making business with a small investment can have a long-term benefits. The implementation of this patent, the battery can be plagued our country's industrial development and environmental protection recycling used batteries use satisfactorily solved problem!

For biogas production, there is a group of several opera: Changsha have 300,000 biogas digesters, Hunan has 1,450,000, there are 13 million gas tank happened; as soon as possible if we can put this add trace elements from waste dell 5081p constitute the "gas fermentation enhancers "developed will not only promote biogas pool happen" premature "can also encourage them to" production ", and its inestimable benefits!

Market Forecast:

At present, including inspiron 700m battery, including the recycling of industrial wastes has attracted the world attention to the use of renewable resources industry has also become the world's good sunshine industry. However, because of lack of scientific, economic, and sophisticated methods of treatment, recycling costs are too high, both at home and abroad for the first battery recycling initiative is not high; this project breaks new ground in the world to fill the gap, therefore, in accordance with environmental protection and recycling economy required an annual demand of 200 sets are possible.

Investment-benefit analysis:

The project for the manufacture of machinery and equipment category, 40 million yuan of investment: one of five million yuan to add equipment, product publicity, 35,000,000 yuan of liquidity, to take every step of sales, an annual output of waste inspiron 710m battery production line equipment, 200 sets; annual output value 130 million yuan, annual profit of up to 33,617,120 yuan.

Cooperation:

Financing, joint venture, cooperation, and the risk of investment, technology transfer, such as can be.

Speaking of Recycling used laptop batteries, no stranger to everyone. Several years ago, the state control of used batteries from the perspective of pollution of the environment, and vigorously advocate for the public to use after the used batteries into special bins. One time, scrap battery recycling bins have become the people living in the landscape.

However, who lives in a community the very fact that Beijing has thus made a depression. All along, the very fact and the neighbors will be used batteries into the dell laptop battery
recycling box community, with the passage of time, the battery recycling box is full, can be left to right, etc., etc. is not someone be taken away, so the hands of residents there was not any of the used batteries at home.

To this end in the U.S. to worry about when, recently, community residents to be heard in another way ©¤ ©¤ formal end-of-life battery can be used for general waste disposal, which under the Real to stir up troubles for the U.S.. Waste Recycling batteries need in the end? If necessary, then who will be responsible for recycling? Used inspiron 6000 battery can be used as ordinary garbage true?

Ordinary mercury-free batteries achieve a drug-free

In fact, the used inspiron 9300 battery can be used as ordinary garbage is not groundless. At National Development and Reform Commission issued the "Waste Battery pollution prevention technology policy" had clearly pointed out that the public commonly used on the 5th, on the 7th Recycling disposable batteries do not have to, but rechargeable batteries and button batteries heavier pollution, we must focus on recovery by the manufacturers Members of the public may not be readily discarded. In response, environmental protection expert analysis, say the past must be disposable Recycling used batteries, the main reason there are more contaminated by the toxic heavy metal mercury. As China's battery manufacturing technology improvements, the current domestic sales of alkaline batteries have reached the level of mercury-free. Therefore, from the perspective of environmental protection, these waste of disposable batteries trash scattered deal with everyday life, does not pose environmental hazards.

Well, apart from the more serious pollution of rechargeable inspiron 9400 battery and button batteries must be recycled, the ordinary disposable batteries Add recycling bins do not have it? In fact, scrap battery recycling has been the problem is not limited to environmental pollution, with the development of science and technology, the potential value of recycling has given its new meaning.

"Urban mines" urgent need to develop

Introduction According to industry experts, civil disposable dell 310-6321 can be divided into two kinds of batteries and rechargeable batteries, rechargeable batteries are nickel and cobalt concentrates, and its nickel and cobalt content at around 20% -30%; disposable batteries is zinc concentrate, the most common zinc manganese dioxide batteries up to 22%, and some also containing nickel, iron, manganese. In recent years, non-ferrous metal resources in the international market more and more scarce, the increasingly higher prices, while the used batteries from rich non-ferrous metals, the potential value can not be ignored. Generally speaking, five tons of ordinary dry-cell batteries can be recycled to produce 1 ton of zinc, the market price of a few million, while rechargeable battery recycling production a higher nickel and cobalt prices, had reached 50 per million.

Reporter at random on some members of the public interview, dell 310-6322 and battery recycling bins small bins received no answer to frequent. On the other hand, specializes in recycling used batteries at the enterprises for the production line of "food" is to worry about. "At present, Shenzhen City, 90% of the civilian batteries are not recycled, which is equivalent to a year in vain to throw away 3000 tons of metal, a great pity." Grammy in Shenzhen High-tech Co., Ltd. Xu Kaihua express this.

Now, with the development of urban construction and people's consumption level, the number of used d5318 is increasing, species are continually expanding. At the same time, because of scrap battery recycling renewable resources such as the lack of a unified, long-term management, and many self-employed self-operated outlets, an East, West, a very scattered. In addition, the majority of operators in order to profit, for the comprehensive utilization of renewable resources, lack of awareness, and the acquisition of the decentralized network management operation also led to difficult questions, such as law enforcement difficult. These reasons lead to the life of the used batteries are not efficiently used, only piled up in the garbage dump or landfill Living with the underground as the "city of mine."

In this regard, the experts called on to explore the set up in line with China's focus on recycling of used g5260 , the disposal of the use of the system of social construction of important questions that need urgent solutions.

Government regulation is the key

Today, many provinces and municipalities have recognized the importance of recycling, have begun to dispose of used g5266 for recycling job.

March 13, Hubei Province, officially launched the city to collect used batteries ring network, the future, the Wuhan city circle nine cities (Wuhan, Huangshi, Ezhou, Xianning, Huanggang, Xiaogan, Xiantao, Qianjiang, days door) will be carried out simultaneously centralized disposal of used latitude cpi battery.

With the "Shenzhen Special Economic Zone to promote circular economy regulations," the official implementation, Shenzhen City, also beginning at Baoan, Futian, Longgang District 6, such as separation and recycling of used batteries to start activities at the event, the Recycling used inspiron 8200 battery were set up over 1200 points months, initially covering the whole set up in Shenzhen used batteries Recycling Network.

While some provinces and cities have begun to focus on recycling of used inspiron 8000 battery for disposal, but at most there is no centralized disposal area, recycling of used batteries are still scattered without chapter.

Faced with the current status of our country used battery recycling, the experts recommend, first of all, the Government needs to build a circular economy system of laws and regulations, norms to promote the development of recycling economy; Second, the norms of the management of waste inspiron 8100 battery recycling.

The use of renewable sources of waste battery production enterprises permit fixed-point production management system, establish a unified regulatory body, at the same time set up national or regional waste processing inspiron 4000 battery recycling and reuse network, strictly limit the access of renewable manufacturing industries threshold. Subregion in the domestic set up and support for the Secondary Lead 3-5 large plants, so that our country scale implementation of renewable industries.In addition, the country needs to strengthen the renewable industry recycling economy of scientific research and development support, through the industrialization of scientific and technological achievements to support the policy, select the priority group to adopt advanced technology of renewable projects, for the regeneration of industrial circular economy to provide a model of technological innovation.

To AA 2300mAh Ni-MH rechargeable sony np-f750, as an example, to express the battery 230mA (0.1C) charge 16 hours after 460mA (0.2C) discharge to 1.0V, the total discharge time of 5 hours, the release of the electricity for the 2300mAh. Correspondingly, if the 230mA current discharge, the discharge time is about 10 hours a day.

Battery internal resistance is the current flowing through the sony np-f960 when the internal resistance. The internal resistance of rechargeable batteries is very small, with specialized equipment required can be measured more accurate results. General knowledge of the internal resistance of batteries are recharged state resistance, meaning that the battery is full when the electric resistance (the corresponding state discharge resistance are that the battery fully discharge the internal resistance. Generally speaking, the discharge state resistance Charge-state resistance than the large, and not very stable).

The greater the battery internal resistance, the sony np-f970 itself consumes energy more efficient use of battery lower. Great resistance at the battery charging very much heat, so that the battery temperature rises rapidly. On the impact of batteries and chargers are great.
