How does EPS work in a fire?
Emergency Power Supply (EPS) in a fire works as follows:
Normal power supply mode
When the municipal power supply is normal, EPS is in the charging standby state. At this time, the mains supply power to the important load through the mutual input device, while the mains detection and battery charging management, and then the battery pack provides DC energy to the inverter.
Emergency power supply mode
When the municipal power supply is interrupted or the mains voltage exceeds the limit, the intercasting device will immediately switch to the inverter power supply. With the support of DC energy provided by the battery pack, the power used by the user load is AC power converted by the inverter of EPS, rather than from the mains power.
Automatic switching
The EPS system is equipped with an automatic transfer switch (ATS) that detects outages and seamlessly transfers the load from the primary power supply to the backup power supply (i.e., the EPS system). This ensures continuous power supply for critical fire protection equipment.
Monitoring and control
The EPS system is equipped with a monitoring and control mechanism that continuously monitors power status, battery health, and system function. This allows any problems to be identified in a timely manner and ensures that corrective action is taken in a timely manner.
Restore power supply
When the mains voltage returns to normal operation, the EPS control center sends a signal to automatically shut down the inverter, and also performs the switching operation from the inverter power supply to the AC bypass power supply through its transfer switch. Thereafter, the EPS provides mains power to the load through the AC bypass power supply path, while also charging the battery pack through the charger.
Hardware composition
EPS power supply consists of rectifier module, storage module, inverter module and intercasting module. The rectifier module rectes the three-phase AC into direct current, which charges the storage module. The inverter module inverts the electric energy of the storage module into AC power with adjustable frequency for fire fighting load. The function of the intercasting module is to transfer the power of EPS to the load in time when the fire needs or the municipal power grid is cut off.
Emergency power supply features
As an emergency power system, EPS is widely used in the field of fire protection. It can realize microcomputer monitoring and microcomputer processing, and the product is fully automated and modular, providing backup power support for fire emergency lighting, fire rolling curtains, smoke exhaust fans, water pumps, fire elevators and other important fire fighting facilities.
CONCLUSION
Through these working principles, EPS ensures the continuous operation of critical firefighting equipment and systems in emergency situations such as fires, thereby improving the safety of buildings and the efficiency of personnel evacuation.
