一起水轮发电机转子动态接地故障及其处理

A Dynamic grounding Fault of Hydraulic Generator rotor and Its Treatment

石龙水电站2号水轮发电机试运行时发生转子动态接地故障,由于动态接地点较难查找,若采用传统方法查找,工作量大,时间较长。文中介绍了一种简便有效、快速查找接地点的方法,并分析了产生动态接地故障的原因。

A rotor dynamic grounding fault happened in test operation of No.2 hydraulic generator in Shilong hydropower station is described.Because it is difficult to find the fault location,traditional methods used are usually troublesome and time-consuming.A new effective and fast method to find fault location is introduced in the paper,and the reason causing the rotor dynamic grounding fault is analyzed.
