摘要
对一起6 kV开关拒动事故进行简要介绍,对开关拒动原因进行详细分析,针对拒动原因进行了二次回路改进,完善了开关的合跳闸监视回路,消除了由于开关合跳闸回路故障不能及时发现造成的开关拒动。
This paper briefly introduced an accident of a 6 kV circuit breaker refusing action, analyzed the cause of the accident. For the cause, the secondary loop was improved and the circuit breaker closing and tripping monitoring loop was perfected so that the breaker refusing action due to the failure of breaker closing and tripping loop was eliminated.
