Aviation DC contactor because of its small volume load characteristics,high reliability,long life,is widely used in aircraft electric parts of each big system.It is of great importance in modern aircraft electrical control unit.The DC contactor in the process of opening and closing,the contact part will get electrical erosion.When erosion reaching a certain degree,dynamic and static contact parts will be welded together,contactor will be out of control and cause the important system fault in the aircraft power supply.Based on the fault analysis of a starter contactor of a certain type of aircraft,and combining with the average fault rate of the contactor in 2016-2019,the suggestions on the timely control management of the component are put forward,which can effectively prevent the occurrence of major faults of other aircraft systems caused by the fusion welding of contactor.
