弹簧操作机构高压断路器与重合闸配合问题的浅析

Simple Analysis of the Problem of High Voltage Circuit Breater with Spring Actuating Mechanism and Reclosing Match

针对某500kV变电站SF6弹簧操作机构断路器与许继WDLK862A断路器保护重合闸配合时,合闸弹簧未储能闭锁重合闸与断路器SF6压力低闭锁重合闸两种设计方案进行详细分析,指出了断路器在发生某些异常,根据分析,运用中的两种方案均不完整,故提出了三方面解决方法。

For the two schemes that the SF6 spring actuating mechanism in a certain 500V transformer substation with WDLK862A circuit breaker protection reclosing match the closing spring does not store up energy to latch the reclosing and SF6 circuit breaker and low pressure latch the reclosing are analyzed.Point out some abnormal phenomena of the circuit breaker,according to the analysis,the two schences are not complete,thus three schemes are put forward.
