I. Introduction
EPS (Emergency Power Supply) is an abbreviation of English for emergency power supply. EPS is widely used in industrial and civil buildings and other sudden power outage accidents will cause important production and life of important economic losses of the power supply load, is an important part of modern building safety and security facilities. The general condition of EPS is to serve as a back-up support power source for fire or production use in emergency situations. For example, in high-rise buildings, shopping malls, hospitals, rail transit, underground shopping malls and other places where there are many people and the export is small, the consequences will be disastrous. At the same time, the fire brigade will not be able to implement disaster relief work because of lack of power supply, which will further increase the degree of disaster. It can be seen that EPS plays an increasingly important role in the security of modern society and is the patron saint of the “Urban Lifeline Systemâ€.
At present, the control method and control method adopted by EPS are different. The load brought by EPS can be summarized as follows:
First, the EPS is mainly used for emergency lighting and accident lighting;
Second, in addition to emergency lighting, accident lighting, there are three-phase series of EPS applied to air conditioners, elevators, rolling doors, exhaust fans, pumps and other mixed loads;
The third is the frequency conversion series EPS that directly supplies the motor. This article describes the most comprehensive hybrid load three-phase series EPS power supply.
Second, based on Shenchuan SVF-EV series of inverter in the EPS system application
Shenchuan EPS solution mainly uses the inverter to serve as the inverter AC motor drive function of the fire system fan pump shutter door. Shenchuan EPS special-purpose inverters can realize the real connection of common DC busbars, which can be used not only in the EPS industry, but also in the chemical fiber and glass manufacturing industries. Can achieve the same input and output phase. To meet the application of special occasions. In view of the particularity of the motor drive in the EPS industry, SVF-EV series inverters mainly increase parameters such as automatic torque compensation, torque compensation limitation, and abnormal restart to meet the needs of special industries. The EPS charging module that is matched with the inverter reduces the cost for the customer, reduces the heavy transformer, and reduces the transportation cost.
2.1 Overall overview of the EPS dedicated machine
One of the main features of the Shenchuan EPS dedicated machine is its ability to achieve a common DC bus, thereby expanding the application area of ​​the EPS dedicated machine. At the same time, the internal DC of the contactor and the cooling fan circuit meets the requirements for direct start-up of the EPS dedicated battery. With the appropriate low-frequency wave transformers and transformers, Shenchuan EPS special-purpose inverters can constitute a highly-reliable hybrid load-specific inverter. And ensure the inverter's output voltage stability and waveform smoothness. Shenchuan EPS emergency power supply inverter can meet the application of the EPS industry in most occasions, is a preferred inverter for EPS manufacturers.
2.2 Functional Features of Shenchuan EPS Special Frequency Inverter
(1) DC power is applied to the control power supply and contactor of the inverter, so direct DC power supply can be fully realized.
(2) Superior hardware and software protection features ensure the reliability of the drive.
(3) A variety of modulation methods are included so that a variety of transformers can be applied, thereby ensuring that the output voltage waveform is closer to a sine wave.
(4) Shenchuan EPS special inverter has AC380V, AC220V two specifications, power range from 0-220KW, to meet the needs of customers in different occasions.
2.3 Shenchuan EPS special frequency converter application design
Third, the conclusion
Shenchuan EPS special-purpose frequency converter truly realizes the customized service and is completely developed according to the technical characteristics of the EPS industry to meet the needs of the EPS industry customers. Shenchuan Inverter has been praised by users for its strict quality management and high cost performance. Through the quality management of Fukagawa, excellent performance and strong technical support capabilities, we have truly realized customized services.
