摘　　要：为考核永磁断路器在线路短路故障情况下的动作特性,本文介绍一种利用短路发电机三相直接试验的原理,模拟突发短路故障,从开断次数、分合闸参量以及燃弧时间参量三方面对永磁断路器(柜)的动作特性进行比较的试验方法;最后,通过开断测试方式T100S,进行30次的15"O"和15"CO"的20 kA额定短路电流开断实例测试,验证了该试验方法的合理性与有效性。In order to evaluate the operating characteristics of permanent magnet circuit breaker under short circuit fault condition, this paper introduces principle of a three-phase generator directly by short circuit test, simulation of sudden short-circuit fault, the breaking capacity of frequency, switching parameters and arc time parameters of three aspects of the permanent magnetic circuit breaker （cabinet） test methods were compared action characteristics. Finally, through the ＂T100S＂ breaking test mode, perform 30 times 20 kA rated short- circuit current interrupting test for 15 ＂O＂ and 15＂ CO＂, the rationality and validity of the test method have been verified.
