摘　　要：错误接线是电能表应用中的常见问题,严重影响供用电双方的经济利益。研究电能表的错误接线方式,对电力部门故障分析、电能核算具有重要意义。以三相三线电能表为研究对象,通过构建电能表接线测试平台进行电能表错误接线实验,采用构建错误接线功率查对表、进行错误接线对照组实验的方式,分析三相三线电能表错误接线运行情况下电能表显示的用电信号特点。Wrong wiring of electric energy meters is a common problem in the application of electricity meters which seriously affected the economic interests of both power suppliers and consumers.Studying the wrong wiring mode of electric energy meters is of great significance for fault analysis and electric energy accounting.Taking the three-phase three-wire watt-hour meter as the research object,the watt-hour meter wrong wiring experiment was carried out in this paper by constructing the test platform for watt-hour meter wiring,and the characteristics of the electrical signal displayed by the watt-hour meter under the condition of three-phase three-wire watt-hour meter wrong wiring operation were studied and analyzed by constructing the wrong wiring power check table and conducting the wrong wiring control group experiment.
