技术背景：technical background:

目前，继电器盒、接触器盒等内的电气线路的检测一般都采用万用表，使用很不方便，检测效率也很低，加之电连接器的插针密集，容易点错触点，而且有些继电器盒内的线路较复杂，检测较为困难也耗费时间。尤其在检测继电器电路的工作(常开)与释放(常闭)时，常需要带电操作，在检测中难免因点错触点而产生短路现象，烧坏电气元件，严重时还损坏设备。At present, the detection of electrical circuits in relay boxes, contactor boxes, etc. generally uses a multimeter, which is very inconvenient to use and has low detection efficiency. The circuit inside is more complicated, and the detection is more difficult and time-consuming. Especially when detecting the work (normally open) and release (normally closed) of the relay circuit, live operation is often required. During the detection, it is inevitable to cause a short circuit due to wrong contact, burn out the electrical components, and even damage the equipment in severe cases.
