Background

The electric meter is a device for metering the electricity consumption of a user and is a basis for carrying out expense settlement between a power supply enterprise and the user. The metering of the electric meter is accurate, namely the electric meter is used for guaranteeing fair electricity consumption transaction and is also an important basis for normal operation and scheduling of a power grid. And the electric energy meter in operation can have the error out of tolerance because of the influence of environmental conditions, such as temperature, humidity and the ageing of components and parts of self. Therefore, the current power supply enterprises adopt a mode of forced electric meter retirement rotation for 6-8 years, and the accuracy of electric meter metering is guaranteed. The periodic rotation of the electric meters is a part of closed-loop management of a power supply enterprise and plays a role in operation quality supervision. The rotation period of the electric energy meter with long service life or the electric energy meter with high quality can be properly prolonged, and the performance of the electric energy meter are checked and checked stably after long-term operation.

When the ammeter is replaced, the user is required to be powered off when the incoming line is cut off, and the electricity is supplied again after the replacement is completed. Although the time required for replacing the electric meter is only a few minutes for each household, the power is cut off on the whole floor, and the power supply is recovered after all the electric meters are replaced. Along with the development of economy and science and technology, more and more intelligent electrical appliances are used by users, and the tolerance to power failure is lower and lower. Although the period of 6-8 years is long, the user still has great trouble when the electricity meter is replaced after power failure, and meanwhile, a power supply enterprise loses a great deal of economic benefits. Therefore, a technical scheme for continuously changing the electricity meter needs to be developed.
