| Abstract: | Material transfer and welding caused by the arc are the main performance of erosion of the silver filmed copper electrical contact,so that electrical contact can not work normally,then relay failure,impacting the operation of the entire circuit.In this paper,simulating the relay the actual work is the purpose of analysis of material transfer and welding mechanism of the silver filmed copper electrical contact of under electrical arc. |
