The multi-user electronic energy meter adopts the method of "different electricity consumption and centralized detection", which effectively prevents the generation of artificial false data during the conduct of electricity stealing and meter reading, and the design of strong and weak electricity is separated. The structural design uses the longitudinal vertical single-direction design, coupled with the complete separation of the strong and weak currents, so that in most cases of maintenance, the power meter does not need to be powered off to replace the weak current parts, but by replacing the voltage stabilizer board, main board, metering board, and communication Unit circuits such as boards and relay driver boards.

Multi-user electric energy meters can reduce potential safety hazards. Take college dormitory apartments as an example. At present, security multi-user meters are common in the market. The main functions of this multi-user meter include: anti-theft, prepayment, remote meter reading, remote control, overload protection, timing power-off function, and vicious load identification.

Although the multi-user electric energy meter has only been developed in recent years, compared with the traditional electric meter, the multi-user electric energy meter has greatly improved in terms of performance and use.

1. Multi-user watt-hour meter saves energy. Compared with the previous watt-hour meter, the multi-user watt-hour meter supplier has the characteristics of household metering, centralized collection, cycle display, small size, high precision, safety and reliability, etc., which can realize single/ The three-phase mixed juice volume and high-power electricity metering can effectively eliminate waste of energy.
2. Multi-user electric energy meter saves space. Multi-user electric energy meter has multiple households with one meter, and integrates electronic technology and computer technology. It has a small size and can accommodate a large number of households. Some multi-user meters can currently accommodate 39 households. Of course, this is also related to the current size. At the same time, it has the function of "one household, one meter". It is worth mentioning that there is currently another type of fully electronic intelligent multi-user watt-hour meter on the market. It is centered on a single-chip micro-controller and adopts a fully modular structure, which can measure the power consumption of multiple users at the same time. din rail meter also independently monitors the power consumption status of each user, and displays the cumulative power consumption or remaining power of each user cyclically, which not only saves space, but also achieves accurate measurement.
