摘要
针对LW10B型SF6断路器机构的打压频繁问题,笔者通过对LW10B型SF6断路器机构的解体分析,发现油泵出口逆止阀是造成机构打压频繁的主要原因,对逆止阀存在的问题进行分析,提出了解决方法。
To solve the problem of frequent pressurizing in LW10B-252 SF6 circuit breaker, cause analysis was conducted via disassembling the breakers. Subsequently, the outlet check valve of oil pump in the circuit breaker mechanism was found the source of frequent pressurizing. A solution to the check valve problem is therefore suggested.
