摘 要: 对三相电容器的暂态过程进行了研究,提出采用接触器和小电流晶闸管组成混合开关,实现了合闸时无冲击电流及分断时无电弧。使晶闸管和接触器的寿命得以延长。晶闸管是瞬间工作,可采用小电流管,使成本降低。 This paper researches on three phase capacitor transients,presents a combined switch constructed of contactor and low current thyristors to realize non surge close and non arcing break.So capacitor and contactor can be used longer.Because the thyristors work instantaneously,low current thyristors are used,then cost is reduced.
