Abstract
For the SF6 high-voltage breakers,when the short-line fault occurs,because of the higher rising rate of initial transient recovery voltage (TRV),it's harder to clear the fault current.This paper provides a comprehensive research about the triangle wave TRV,based on the process of traveling waves and short-line fault test in laboratory.Based on PSCAD simulation,comparing low-voltage simulation and high power test,the influences of the stray parameters of artificial line and the capacitance of the diode,on the actual results during high-power test are analyzed.Eventually come to the conclusion:first,the actual capacitance value is lower than PSCAD simulation,because of the stray capacitance;second,the actual parameters in high power test are higher than low-voltage simulation,because of the capacitance of the diode,so,try to adopt small current and multiple diode series modes.关键词
