Due to some historical reasons and other factors, China has been producing electric energy meters for a long time. Electricity meter manufacturers and electric power departments do not pay enough attention to the life of electric energy meters. In order to ensure the accuracy of the measurement work, the power department has formulated regulations for the regular replacement of electricity meters. With the gradual implementation of one household and one meter for urban and rural residents, power companies urgently need electromechanical long-life energy meters as energy meters for the transformation of the two networks. At present, several large domestic electric energy meter production plants have increased their research and development efforts, and the annual output of electromechanical long-life electric energy meters has exceeded one million units.

Electromechanical energy meters produced in developed countries such as Europe and the United States are basically long-life energy meters. The non-maintenance time is usually about 20 years, and Japan sets it to 15 years. With the development of electric energy meter manufacturing technology, there have been continuous operation of single-phase electric energy meters abroad for more than 40 years. This is what we call a long-life energy meter. In response to the development of the domestic instrumentation industry and the overall future development trend, the original State Machinery Industry Bureau stipulated that China does not maintain electromechanical long-life electric meters for 20 years.

The key to extending the life of electromechanical meters is to ensure the manufacturing quality and advanced processing technology of each component in the table. The choice of raw materials is the basis for ensuring quality. The graphite ring is a key part of the energy meter. The relatively mature similar products of large foreign companies should be selected whenever possible. Domestic electromagnetic bearing factories should be produced in strict accordance with national standards, and electric energy meter manufacturers should also prefer to choose electromagnetic bearings approved by the national quality certification to prevent inferior electromagnetic bearings from entering the electricity meter market.

The key magnetically permeable materials should be selected from the products of major domestic steel companies and manufactured in strict accordance with the process. Ensuring the quality of components and adopting advanced processing technology is the basis for the long service life of electric energy meters. The electromechanical long-life watt-hour meter has a high degree of integration. Each component is processed by a special process, which not only overcomes the problem of easy aging of electronic components, but also overcomes the shortcomings of general electromechanical energy meters, and can be used in various harsh environmental conditions.

The meter is made of special materials and has the characteristics of small and constant friction torque that does not produce lubrication for a long time. Each type of electromagnetic components (such as electromagnetic components) are processed from raw materials and subjected to high-temperature vacuum annealing to eliminate stress, thereby meeting the needs of extending service life and stable performance. The electromechanical long-life electric energy meter can also be equipped with a pulse generating device, which is convenient for calibration and remote automatic meter reading, meter reading and development of the electricity market. The voltage coil is potted with epoxy resin to meet the requirement that the insulation strength does not decrease during long-term use.
