When a fault occurs, line inspectors need to check the addressers on the distribution lines at all levels to determine the fault point. The quickness requirements are still not resolved, and the fault cannot be quickly and accurately judged Section, line inspection is time-consuming and difficult, and accidents cannot be dealt with in a timely and effective manner, which may easily cause power grid losses.

2、其报警显示单元一般利用机械结构实现状态转换，长期使用后易失效，如一直保持报警状态等，所以其检测精度受到极大影响，同时造成安装和维护成本高。 2. The alarm display unit generally uses a mechanical structure to achieve state transition, and it is prone to failure after long-term use, such as maintaining an alarm state, so its detection accuracy is greatly affected, and at the same time it causes high installation and maintenance costs. the
