10 kV高压同步电动机定子对地击穿分析处理

Analysis on the Earth Breakdown of stator in 10kV High Voltage Synchronous Motor

简要叙述２号高炉鼓风机同步电动机（４８０００ｋＷ）由于受突发外来冲击高压定子绕组对地击穿的故障分析机理，以及处理对策和决定依据。

An analysis is made on the mechanism of the earth breakdown of the stator winding arising from the impact of a sudden external high voltage on the synchronous motor(4800kW)for No.2 BF blower,and a basis for the counter measures are put forward as well.
