This paper analyzes the fast switch action process in the three accidents of the generator tripping happended in Wenergy Tongling Power Generation Co ., Ltd.#3 unit.Through the analysis and the test , it is proved that the reason of the fast switch action during the electric pump interlock startup , causing the 6kV bus voltage to reduce , then resulting in the decrease of the 400V voltage, the auxiliary generator tripping after the AC contactor return of the 400 V auxiliary generator control circuit .And the corresponding processing methods are put forward .
