摘　　要：容性电流开合试验是高压交流断路器的重要试验项目。近年来,超(特)高压断路器在系统和试验中开合容性电流时遇到不少问题,例如特殊环境条件下频繁重击穿、恢复电压多个周波后发生重击穿和NSDD。文中研究分析了这些典型问题,探讨了现行的相关标准和试验方法的缺陷,介绍了滤波器组用断路器的新试验项目及经验,是对现行标准和试验方法的完善所做的一次有意义的探索。Capacitive current switching test is an important test for high voltage ac circuit breaker. In recem years, the EHV and UHV circuit breakers have encountered many problems when they switching capacitive current in system and test, such as frequent restrikes under special environment condition and non-sustained disruptive discharge （NSDD） and restrike after more than one cycles of recovery voltage. In this paper, these typical problems are researched and analyzed, the imperfections of current relevant standards and test methods are discussed, the new tests and experiences of the circuit breaker used for switching filter bank are introduced. This paper is a meaningful exploration for the improvement of the current standards and test methods.
