用断相保护继电器获取断相信号，据输出电压变化构成断相保护电路实现保护。
Short-phase relay obtains short-phase signal, short-phase protection circuit was formed according to change of output voltage to realize short-phase protection.
其中电器类产品有液晶显示计时计数器、平层感应器、断相错相三相交流保护继电器等等。
Electrical products which have LCD time counter, Layer sensor, Three-phase AC fault protection relay and so on.
该继电器采用集成电路构成，集线路的速断保护、过电流保护及三相一次重合闸于一体。
The relay is made up of integrated circuits. The line instantaneous overcurrent protection and overcurrent protection are combined with the once 3-phase reclosure application to form a whole body.
