Application of battery charge and discharge tester in power system
The specific functions and maintenance methods of batteries in substations
In a substation, the battery is an important part of the DC power supply system in the power supply used in the substation. It mainly provides stable power support for the secondary system in the substation system. Unlike the AC power in the station, the battery is usually used as a backup power supply at full power for a long time. In the capacity floating charging operating state, when the alternating current in the station is working normally, it mainly provides closing power for the circuit breaker. Once the system in the station fails and a tripping accident occurs, the battery will continue to provide relay protection, automatic devices, and short circuits in the substation system. Tripping and closing, rectifier equipment for driving mechanical equipment, communications, etc. provide power and maintain it for a specified time to ensure that maintenance personnel can perform emergency repair operations on system faults during the power supply period, thereby effectively avoiding the occurrence of substation safety accidents caused by system faults. And since the substation plays an important role in voltage rise and fall and power distribution in the entire power system, the stability of the substation battery is also of great significance to the normal operation of the entire power system.
Therefore, it is very important to maintain the stability of the battery performance in the substation. It is necessary to maintain the substation battery through reasonable daily maintenance of the battery, strengthening periodic inspection of the battery, implementing fire protection measures for the substation battery, and reasonably setting operating parameters.
