| 摘 要： | 针对一起因老鼠进入电站变压器室造成单相接地起弧发展成三相短路的事故,分析了造成这起事故的几个原因。通过计算短路点的短路电流,说明原电流互感器额定热稳定电流太小。采用新型号的电流互感器及加强了母排的绝缘保护后,消除了故障隐患,保证了用电安全。

| Abstract: | In view of the three-phase short circuit accident resulted from mouse entering the transformer room, several reasons are analyzed. The short circuit current calculation shows the rated thermal stability current of former current mutual inductor is too small. Using the new type current mutual inductor and enhancing the insulated protection of bus removes the trouble hidden and ensures the power running safety. |
