这是一种引出并联探头、可探测电子或某些物质的移动变成漏电信号输入开关、断电报警同时进行的多功能漏电保护开关。适用于工厂、发电厂、农村打麦场、剧院、商场、家庭等。可检测漏电、火灾、水灾、防盗、地震、煤气漏气等报警。还可测家电和三相电器,可测大型发电机组和大型变压器自身的漏电,配合附件,可实现对发电机组自动关机或切断变压 This is a multi-functional leakage protection switch that leads to the simultaneous movement of a parallel probe, detectable electrons, or some substances to become a leakage signal input switch and power off alarm. Applicable to factories, power plants, rural wheat farms, theaters, shopping malls, families and so on. Can detect leakage, fire, flood, security, earthquake, gas leak alarm. Also can measure home appliances and three-phase electrical appliances, can measure the leakage of large generator sets and large transformers itself, with accessories, can automatically turn off the generator set or cut off the pressure change
