Experimental Investigation on Breaking Characteristic of Load Switch in Medium High Voltage Ring Network Cabinet

Abstract:

This paper focuses on an experimental investigation of the arc plasma behavior in current breaking process of a certain type of 12kV ring network cabinet’s SF₆ load switch. From the frames obtained by high-speed photography, the characteristic of the arc movement was revealed. According to analysis, the structure of load switch was optimized and its breaking capacity about transfer current was improved. This study may provide a reference for design and optimization of load switches.
