Abstract: Based on analyzing the principle, characteristics and capacity factors of VRLA batteries the voltage detection method and internal resistance detection method are compared. According to the characteristics of 11o kV substations, the method of on-site maintenance of battery is put forward. The internal resistance test verification for different batteries is build by the hand-held intelligent battery resistance tester, and the test criteria of internal resistance of battery are summarized.
Keywords: VRLA battery; on-site maintenance; 11o kV substation; capacity; voltage; internal resistance

护和断路器拒动,引发重大的电网事故。例如:当 2016年某330kV变电站(与某110kV变电站共址建设)外有一35kV出线电缆中间接头爆炸,站内所用交流电源失去时,直流电源未能提供应急电能,保护越级跳闸,造成事故扩大,导致330kV 和110kV主变压器着火烧损的严重事故。
在变电站直流系统中,蓄电池的稳定性和放电容量对直流系统安全运行起决定性作用。《国家电网公司变电运维管理规定第24分册站用直流电源
