摘　　要：针对低压开关设备的接通和分断能力测试中常见的极间、极与框架的闪络故障,利用差动保护原理,设计了一种报警装置并进行了试验。试验结果表明,监测装置可有效提取通断试验中的闪络故障信息,并及时提供报警。According to the failure of flashover occurring between poles or between poles and frame in making and breaking capacity tests of low voltage switchgear,a warning device based on residual current protection was designed. The practical results prove that the device can capture the failure of flashover and generate the warning signal.
