摘　　要：针对35kV真空断路器开断无功补偿装置时发生重燃的实际情况,分析了其电弧重燃产生过电压的机理。根据国内现行的相关标准,提出了在电容器组电源侧加装氧化锌避雷器MOA的保护措施,并应用ATP软件对实施保护前后的过电压值进行了仿真计算,结果表明此措施达到了良好的限压效果。The reason of arc restriking overvoltage is analyzed in view of the restriking condition when the 35kV vacuum circuit breaker breaks the reactive compensation device. The protection measure by adding MOAs at the power source side of the capacitor group is proposed according to related national standards in the paper. The overvoltage values before and after applying the protection measure are simulated and calculated using ATP software. The results display that the voltage restriction effect is very good.
