Abstract

Current-carrying arc got contact surface worse and influenced the transmission of electric energy. Arc burning process and arc characteristics and arc erosion and current-carrying efficiency were tested on a home-made single asperity current-carrying tester under different polarities conditions. Experimental results show: when W probe is anode and copper specimen is cathode, arc mainly belongs to metallic vapour state and arc has long burning times and high arc energy and low electric field intensity. Current-carrying efficiency is high. When W probe is cathode and copper specimen is anode, arc mainly belongs to gas state and arc has short burning times and low arc energy and high electric field intensity. So arc erosion is light and current-carrying efficiency is low.
