摘要
随着真空开关在电力系统网中的应用不断扩大,对其特性的监测也不断升级。电寿命是影响真空开关寿命的重要因素。通过对真空开关开断时的燃弧电流和燃弧时间进行采集和计算,构造电侵蚀率与开断电流的数学模型,最终得出真空开关的剩余电寿命。[1]本文研究有助于实现真空开关的实时在线监测和减少真空开关使用上的能源浪费。
The properties of monitoring for vacuum switch escalate along with its application of the network in power system is expanding constantly. Electrical endurance is the effect of vacuum switch endurance of important factors. Eventually it obtained residual electric endurance of vacuum switch, through vacuum switch breaking circuit of burning arc current and burning arc time collection and calculation then constituting mathematical model of electric erosion rate and breaking current. This paper studies contribute to realize real- time on-line monitoring of vacuum switch and reduce energy waste of vacuum switch.
