智能电能表误跳闸原因分析及处理

Cause Analysis and Treatment on Smart Meter Error Tripping

针对单相智能电能表在运行现场出现的误跳闸现象,从单相智能电能表的载波模块通信原理、内部判断逻辑、跳闸控制继电器控制方式等方面分析误跳闸原因,通过对电能载波模块电压变化的现场测试和实验室测试,验证了误跳闸原因分析的准确性,并提出相应的处理措施。

For the error tripping phenomenon of single-phase smart meter running site, the paper analyzes the reasons of the error tripping from communication theory of smart meter carrier module, internal control relay control logic and controlling of the trip control relay,verifies the reasons for the trip through meter carrier module voltage variation of field testing and laboratory testing, in the end, proposes corresponding measures.
