发电厂升压站主变压器检修完毕,用高压侧断路器向其充电时,瞬间保护动作,跳掉断路器。到底是一次设备有故障,还是二次回路有问题?在查找原因、排除故障时,如何根据故障现象及出现的信号,采取相应措施,少走弯路,尽快恢复送电,这是值得我们研究的议题。
Step up transformer substation main transformer maintenance is completed, with high-voltage side of the circuit breaker to charge, the instantaneous protection action, jump off circuit breakers. In the end is a device fault, or secondary circuit problems? In the search for reasons, troubleshooting, how to fault phenomena and the signal appears, take appropriate measures to avoid detours, as soon as possible to restore power transmission, it is worth our study issue.
