摘要
直流系统是变电站的重要组成部分,它给变电站内继电保护、控制、信号、计算机监控、事故照明、交流不间断电源及断路器分、合闸操作等提供直流电源。而蓄电池是直流系统的心脏,对蓄电池进行科学的检测和维护是直流系统的核心工作。文章介绍了阀控式铅酸蓄电池的原理及特点,对蓄电池运行方式进行了分析,讨论了如何在实际工作中对蓄电池进行正确地检测与维护。
The DC system is an important part of substation. It provides DC power supply for substation relay protection,control,signal,computer monitoring,accident lighting,AC uninterruptible power supply and circuit breaker,closing operation. The battery is the heart of the DC system and the scientific detection and maintenance of the DC system for battery is the core work.This paper introduced the principle and characteristics of VRLA battery,analyzed the running mode of the battery,and discussed how to correctly detect and maintain the battery in actual work.
