摘　　要：罐式断路器抗震性能好,自带外置线包式TA,结构布置紧凑占地面积少,一般来说可靠性高,但近年来河北省电力公司频繁发生罐式断路器内部放电故障,故障现象大多为送电过程中发生放电,通过对故障断路器的故障现象分析和内部放电模拟试验研究认为,罐式断路器内部放电故障主要是由于内部遗留或运行中产生异物造成的,罐式断路器在安装时应严格控制安装环境和运行中异物脱落。目前采取的措施是彻底清扫罐体内部,保证罐体内部清洁度。500 kV tank circuit breaker has good anti-seismic performance, with an external line package type TA, compact configuration, small area and high reliability. However, in recent years, internal discharge faults of tank circuit breaker in Hebei Electric Power Corporation occurred frequently when 500 kV tank circuit breaker was being combined into grid. Through studying on fault phenomenon and experience from the laboratory, it is detected that internal discharge of tank circuit breaker is caused by impurities, so it is important to keep assembling condition clean and avoid the dropping of scraps during operation. At present, thoroughly cleaning up impurities at the bottom of tank circuit breaker is taken to keep inside cleaning.
