背景技术Background technique
在三相四线供电系统中，零线断线或接触不良，都能引起线路电压升高，在工作中我们每年都遇到，因线路短路将零线烧断，使用户电器因为过压而烧坏，给用户带来不便，我们公司就得向用户理赔，造成巨大经济损失。而出现问题后，工作人员到现场排查浪费非常多的时间，而且有时还会无法判断出，导致更深层次的错误发生。In the three-phase four-wire power supply system, the disconnection or poor contact of the neutral wire can cause the line voltage to rise. In our work, we encounter it every year. If it burns out and causes inconvenience to users, our company has to settle claims from users, resulting in huge economic losses. After a problem occurs, it takes a lot of time for the staff to go to the scene to investigate, and sometimes it cannot be judged, leading to deeper errors.
