[1]验电器的种类和原理验电器用于电气设备和电气线路等的带电部分验电。在进行停电作业时,检查线路是否带电。此外,在检查开关接触不良,保险丝是否烧断等设备故障时,也要使用验电器,特别是为防止发生人身触电事故,应随身携带验电器。使用前,必须在另外的带电线路上试测,验证验电器工作正常才能使用。用后,放置在干燥处,要特别注意勿使其绝缘性能降低。 [1] Types and principles of electroscopes Electroscopes are used for the verification of live parts of electrical equipment and electrical wiring. During power outage, check if the line is live. In addition, check the switch is bad, the fuse is blown and other equipment failure, but also the use of electroscope, in particular, to prevent personal electric shock accident, should carry electroscope. Before use, it must be tested on another live line to verify that the electroscope works properly. After use, placed in a dry place, pay special attention not to reduce the insulation performance.
