The device has the advantages of reasonable structural design, capability of switching different functions conveniently and low cost.

Description

technical field [0001] The invention relates to an intelligent electric energy meter verification / digital integrated device. Background technique [0002] With the development of electric power and metering, electric metering and related departments have more and more demands and voices for electric energy meter verification devices with integrated functions of electric energy meter verification and digital operation. The main purpose is to facilitate equipment management and data sharing. The energy meter verification / digital integrated device is a part of the electric energy meter verification device. It integrates all the functions of the electric energy meter verification device and the electric energy meter digital device. a device. In the prior art, the conventional electric energy meter verification / digital integrated device such as figure 1 As shown, it is a quasi-all-in-one machine device, and a pair of first electrical source terminal posts 11A', a pair of first ...

AI Technical Summary

Problems solved by technology

[0007] 1. Too many contacts are added to the current loop, and the contact resistance is increased at the same time. For the high-precision electric energy meter verification device, it will seriously affect the accuracy and stability, as well as the load capacity.

[0008] 2. A large number of additional connecting wires are added, and these connecting wires must be more than 20 square meters, allowing 100A high-current wires to pass through, which increases the material cost, increases the man-hour cost, and also increases the manufacturing difficulty in the process, which affects the appearance

[0011] Its length is quite considerable, switching the universal switch is not something ordinary people can pull, and the operators of the equipment are generally women, the results can be known, so it is very impractical

[0012] 4. Using the relay method, the magnetic latching relay is expensive, and also needs a control module and a working power supply. The cost is a big problem, and there are more wiring

There are still reliability problems during use, etc., which is not advisable
