Pre-paid watt-hour meters are commonly known as card meters. IC cards are used to pre-purchase electricity. Inserting an IC card into the meter can control electricity at a cost and prevent arrears in electricity charges. It is an electronic or electromechanical watt-hour meter. The appearance of this kind of energy meter has resolutely caused the phenomenon of arrears of electricity charges by users in some areas, and also provided convenience for the power system.
The energy control link of the prepaid energy meter is the same as our previous meters. It can accurately calculate the electricity used by the electricity consumer and display these values on the meter's display screen. The automatic trip function of pre-paid meters has most of the traditional meters, this link is to better protect the electricity **. When consumers use too many electrical appliances and the circuit cannot be loaded, they will automatically trip and close all circuits. The consumer needs to turn off some appliances and turn on the meter knife of the meter to continue using electricity.
As an important part of current pre-paid energy meters, its development has an irreplaceable effect on the growth of smart grids. Among them, the structure classification, working principle, and characteristics of pre-paid energy meters will have many aspects. China's smart meters can be roughly divided into two types: mechanically integrated and fully electronic. Therefore, in terms of the development of the meter industry, such meters can largely show that the size of the meter in our country is reduced and the reliability is increased. , More accurate, energy saving and environmental protection, and greatly improved production technology, in a sense, the superiority of the meter industry, ** finally return to the meter with mechanical parts!
