Abstract
Analysis for opening characteristic of circuit breaker is important for improving its performance.This article takes spring operating mechanism of high voltage SF6 circuit breaker as the object of the research,based on working principle analysis of buffer and interrupter from opening operation of circuit breaker point of view,its simulation model of the spring operating mechanism and the interrupter has been established with co-simulation of Adams and MATLAB.The motion characteristic of breaker has been obtained under no-load,the simulation curve can reflect the experimental curve well,which can verify to the simulation accuracy.Then on this basis,through numerical simulation,the variation law of interrupter pressure and buffer force in opening operation is studied.This research is helpful for checking the part strength and the fatigue life.Meanwhile,it can provide the reference basis for improving the breaking performance of the circuit breaker.关键词
