一、introduction
EPS（Emergency Power Supply）Is the emergency power supply English acronym. EPS is widely used in industrial and civil buildings, and sudden blackout accident occurred in the will cause great economic losses to the important load power supply to the normal production and life, is an important part of the modern architecture of security facilities. EPS is generally used as a backup power supply for fire protection or production in case of emergency. Such as in high-rise buildings, shopping malls, hospitals, rail transportation, underground shopping malls and other places of personnel, less exports, natural light source Co., once the fire or grid by destruction, the light disappeared a blackness, multiple people at the same time export less, the consequences will be unimaginable. At the same time, the fire brigade will be unable to display disaster relief work because of the lack of power supply, so the extent of the disaster is more serious. Play an increasingly important role in modern social security EPS visible, is the "city lifeline system".
At present the EPS control mode and control means is different, for EPS with load can be summed up three: one is mainly used for emergency lighting and emergency lighting of EPS; the second is in addition to the emergency lighting, emergency lighting, and application in air-conditioning, elevator, shutter doors, exhaust fan, pumps and other mixed load of three-phase series of EPS. The third is directly to the motor power supply frequency series of EPS. This paper presents the most comprehensive mixed load three-phase series EPS power supply.
二、Yi Chuang fei using EPS system ECF500 series inverter based on the
Yi Chuang Fei EPS solution mainly use the inverter to play the fire protection system of fan and water pump rolling shutter door of the inverter AC motor drive function. Yi Chong Fei EPS inverter dedicated to the true total DC bus connection. Thus, we can not only used in EPS industry, can also be used in chemical fiber, glass manufacturing industry. Input and output phases can be realized, which can meet the application of special occasions. In view of the particularity of motor drive in EPS industry, ECF500 series inverter mainly to increase the automatic torque compensation, torque compensation limit, abnormal restart and other parameters, to meet the special needs of the industry. The EPS charging module which is matched with the frequency converter reduces the cost of the customer, reduces the heavy transformer, and reduces the transportation cost.
Overall overview of 2.1 EPS dedicated machines
Yi chuang fei one of the main features of the fly EPS special machine is able to achieve common DC bus, so as to extend the application fields of EPS is a special machine. At the same time, the direct current of the internal contactor and the partial circuit of the cooling fan meets the requirement of the direct starting of the EPS unit. Yi Chong fly EPS special inverter through a mix of appropriate low frequency filter and transformer, can constitute a very high reliability of mixed load special inverter. And ensure the output voltage stability and waveform smoothness of the inverter. Yi Chong fly EPS emergency power supply special inverter can meet the EPS industry the vast majority of occasions, the application is EPS manufacturers preferred a specific frequency converter.
2.2 Yi chuang fei features fly EPS special inverter
(1) the inverter's control power supply, contactor is the use of DC, and therefore can be fully realized direct DC power supply.
(2) strong hardware and software protection function, ensure the reliability of the inverter.
(3) contains a variety of modulation methods, which can be applied to a variety of transformers, which ensures that the output voltage waveform is more close to the sine wave.
(4) Yi Chuang fei EPS inverter dedicated AC380V, AC220V two specifications, power range from 0 - 220kw, can satisfy the customer different occasions demand.
2.3 yichuangfei EPS inverter application design
(1) circuit principle design. AC DC dual power supply EPS principle as shown in figure 1.
