| Electric energy meter bears certain social service function. It has installation of a large quantity, wide distribution characteristics. If the long-term operation in the process of using the reliability is not high, fault rate is high. Not only because of quality problems caused by replacing the time-consuming and laborious, but also easy to cause electrical disputes, the loss outweighs the gain. With the rapid development of the smart grid, smart meters will be domestic large-scale production and application. It is expected the national grid will be the smart meter coverage will exceed80%, residents of more than14million households in2015. The National Smart Meter coverage will reach100%in2020.Intelligent electric energy meter realizes the power grid enterprises and power grid users information interaction between demand, interactive, harmonious win-win situation, make the social benefit the biggest change, its advantage and advantage is very obvious. With the rapid advance of network meter, ammeter updates faster and faster, function more perfect, also with added functions, fault attendant. And intelligent electric energy meter as an emerging thing, the environment is general electric energy meter is more complex, responsibility is more major, so the study of intelligent electric energy meter common faults and improve its reliability is very important.Because of different policy, climate, environment different, this article only for the Huzhou area of the intelligent electric energy meter is analyzed. This article first introduces the intelligent electric energy meter’s structure, function, operation environment, attention, maintenance, automatic production and detection technology, which focuses on AMI (intelligent power grid measurement system), AMR (automatic meter reading system), the intelligent electric energy meter is the important chip analysis. Secondly, through the early theories of learning, practice, manufacturers such as field surveys, to the cause of intelligent electric energy meter for soft, hardware caused fault research. Finally, according to the different fault reason, to carry on the concrete analysis, process improvement, so as to reduce the failure rate, improve the reliability, reduce the meter failures caused by the power dispute, changing meter, events, and provide a strong backing for the entire power grid. |
