Abstract The failures of AC contactors are mainly caused by the arc erosions during breaking electrical circuits, and therefore, the electrical life of contactors can be increased by controlling the arc erosions properly. The effect of arc starting phase angle (ASPA) on the arc duration and hence the arc erosion was analyzed in this paper, and the differences of the electrical life under three control modes, including the random ASPA control, the fixed ASPA control and the three-phase uniform wear control, were also investigated in detail. The randomness of the ASPA caused by the inconstant release time of AC contactor was analyzed, and then the characteristic of contactor's electrical life under this randomness was analyzed through simulation. A maximum life control method based on the standard deviation of ASPA to control the optimal releasing moment of AC contactor, in terms of minimizing the arc erosion, was proposed in this paper. In application, the releasing moment of contactor can be adjusted properly and automatically according to the real-time operating parameters to maximize the electrical life of AC contactor. Experiments under the three control modes prove that the arc erosions of three contacts are almost the same and the erosion rate is the minimum under the maximum life control, and the electrical life of the AC contactor is significantly increased.

Key words： AC contactor arc erosion optimal releasing moment maximum electrical life control strategy
