摘　　要：智能真空开关主要应用在电容器组、电抗器组、空载线路和空载变压器的投切等4个方面,在输电线路自动重合闸以及短路电流开断方面还处于研究试验阶段。笔者目的是研究真空开关投切不同负载的控制策略。文中首先论述了选相投切的基本原理,然后分析了开关投切不同负载的操作过电压,最后选取电容器组和电抗器组作为容性负载和感性负载的典型,详细分析并总结了考虑预击穿、重燃与机械分散性等条件下,智能真空开关投切电容器组和电抗器组的最优控制策略。Intelligent vacuum breakers is mainly applied in switching capacitor,inductance,on-load line and no-load transformer,and is applied on the stage of research in switching automatic reclosing transmission line and short-circuit current.Purpose of this paper is to study the vacuum switch switching control strategy for different loads.This paper firstly discusses the basic principle of phase selected,and then analyzes the over-voltage of switching different load.Lastly,it selects capacitor and inductance as the typical represents of capacitive load and inductance load,and detailedly analyzes and summaries the intelligent vacuum breaker optimal control strategy in switching different load in considering of advance breakdown,reignite and mechanical dispersion.
