As the indemnificatory power supply system in various important places, the energy storage AC emergency power supply system has been widely used as the "urban life support system". There are mainly two kinds of AC emergency power supplies for energy storage in the market. One is on-line uninterruptible power supply (UPS), which can switch between main and standby seamlessly. It is mainly used for important loads that require power supply not to be interrupted less than 10ms; One is standby emergency power supply (EPS): its switching time between main and standby is about 0.25s, which is mainly used for various emergency loads that require uninterrupted power supply time less than 0.5s s. According to the different requirements of important loads in the field or industry for power supply parameters, both of them have their own advantages and disadvantages.
The rapid development of information, intelligence, monitoring, control, management, energy saving and environmental protection has strongly shocked and promoted the technological progress and functional perfection of UPS products. Many internationally renowned UPS manufacturers are paying attention to the function and market position of EPS. In recent years, the so-called UPS“ECO "operation mode (energy saving mode)," online interactive "uninterruptible power supply," bypass priority "UPS and other new concepts are actually copies of some advantages and functions of EPS. Many EPS enterprises have also introduced a fast emergency power supply system with static switch switching according to the outstanding characteristics of seamless switching of UPS products.
Intelligent Uninterruptible Power Supply System (ISPS) is an independent intellectual property product developed by Guo Biao Group Company, and it is a new type of energy-saving and environment-friendly UPS power supply system. This product effectively solves the technical problem of long EPS conversion time (about 0.25s) of emergency power supply, solves the practical problems of low efficiency, low load rate and poor environmental adaptability of traditional UPS, avoids the fire hazard problem of large heat accumulation caused by long-time online of traditional UPS, and provides a real pollution-free market.
ISPS power supply system is an energy-saving uninterrupted power supply that works in offline mode. When the power grid is normal, the municipal power supply is directly output; When the power grid is abnormal, switch to the online operation mode and output the processed commercial power; When the power grid returns to normal, directly supply power to the municipal government again; When the mains fails for some reason, the emergency power supply is output. This kind of uninterruptible power supply works in energy-saving mode for a long time, and it does not need contactless switch (static switch) to work online. It can not only achieve high efficiency and environmental protection, but also eliminate thermal hazards and prolong its life. Compared with the popular uninterruptible power supply (traditional UPS and EPS) at home and abroad, it has obvious advantages.
With the development of information industry and the rapid growth of computer market, the PC market in China has developed at an average annual rate of 45% in recent years, and the average annual growth rate of UPS power supply for various computing center facilities has remained above 30%, and it will develop at an average annual rate of above 30% in the future; In recent years, the annual growth rate of some program-controlled industrial assembly lines and special EPS (fast switching type) supporting special lighting is higher than 30%; Start of gold information project (such as gold card, gold tax, gold shield, etc.). ) has promoted the rapid development of China's online market. The proposal and implementation of government internet access and enterprise internet access have greatly increased the demand for uninterrupted power supply; The total demand and growth rate of uninterruptible power supply products in IT industry, represented by communication field, are expanding day by day. Energy conservation and environmental protection are two major themes in today's society. Compared with traditional UPS, ISPS power supply system saves energy by 15%, which has important economic significance. It means that our 24-hour online UPS power supply will save 1, 3 1.4 kWh per kilowatt every year, which is equivalent to reducing 8 1.4 tons of CO2 emissions. At present, the annual consumption of UPS power supply in China is close to 3 billion yuan, behind which is a huge waste of material energy and economic energy. In today's energy shortage situation, the advent of ISP will bring great changes to the power industry, and it will be a new direction of energy conservation and environmental protection.
