Abstract This paper introduces two solutions of anti-electricity shaking for AC contactor: lost voltage restart scheme and keep contactor not release scheme. In using the method of qualitative analysis, this paper analyzes the residual voltage of the bus, the residual voltage of the motor and the problem of whether there is a direct restart and anti-phase switching after the voltage recovery, and points out that the combination of keeping contactor not released scheme and quick switching device ensure that the power supply which can be restored quickly, and the impulse current of the system being reduced to minimum.
