35KV手车式开关柜不能合闸原因分析及整改措施

Cause Analysis and Corrective Measures to Broken 35KV Handcart Switch Cabinet

近年来固原变电所的部分35KV断路器经常出现在手跳或保护动作跳闸后由于控制回路断线而不能再次合闸的情况。这种断路器属于手车式开关。经仔细对断路器控制回路检查分析，找出了造成断路器无法合闸的原因，并采取措施，对断路器二次控制回路进行了整改，很好地解决了这一问题。

In recent years, some of 35KV circuit breakers in Guyuan transformer substation often can＇t reclose for disconnection of control circuit after the hand tripping or protection action tripping. This kind of breaker is handcart type switch. After careful inspection and analysis on the control circuit breaker, the cause of circuit breaker which can not be closed is identified, and measures are taken to the secondary rectification for enntrol circuit breakers. Therefore, this problem has got a good solution.
