The Fault Identification And Analysis Of Working Smart Electricity Meter

By analyzing the failure reason of malfunction of the electric energy meter,it can conducive to control the quality of the whole process of the electric energy meter,and discover the meter quality hidden trouble in time,for enhancing the operation reliability of the intelligent the electric energy.Beginning with the necessity of the electric energy meter laboratory test failure analysis, this article parsed the work principle of the electric energy meter and introduced work applied to the fault diagnosis appraisal methods and relevant test project. It mainly introduced the working principle of the seven module parts, such as the display module、the measurement module、the power supplys module、the Master control module、the Storage module、the communication module、the cost control module.Through the statistical analysis of historical fault identification data, this article analyzes the reasons of all kinds of fault phenomena may be encountered in work,It pointed out that each module corresponding common fault phenomena of the electric energy meter.In the work may encounter all kinds of failure phenomenon are summarized.Thus more conducive to find the key points affecting the quality of the electric energy meter, to do a good job of quality control.
