摘要
开关电器的电触头由电接触材料制备而成,在分离时会产生电弧。本文从介质种类的角度,综述了油断路器电弧、空气开关电弧、SF6断路器电弧、真空开关电弧以及固体介质开关电弧的形成机理、灭弧特性及应用,对实现开关电弧的经济和绿色环保具有一定指导意义。
Electrical contacts of switch apparatus based on electrical contact materials will generate arc when they separate from each other. Generation mechanism, arc extinction characteristics and applications of switching arc in different medium are reviewed from the perspective of medium types, including the arc in oil circuit-breaker, air switch, SF6 circuit breaker, vacuum switch and solid-state medium switch. It plays a certain guiding significance in achieving economic green envi- ronmental protection of the switching arc.
