Uninterrupted metering switching device for live replacement of electric energy meter and electric energy meter replacement method

Abstract

The invention provides an uninterrupted metering switching device for live replacement of an electric energy meter and an electric energy meter replacement method. The switching device provides a turnover place for alternating electric energy metering of new and old electric energy meters during live replacement of the electric energy meter, and the safety and the electric energy metering continuity in the live replacement process of the electric energy meter are ensured. The switching device comprises a shell, a voltage input terminal, a current input terminal and electric energy meter binding posts, wherein the voltage input terminal and the current input terminal are arranged on the shell, and the electric energy meter binding posts are at least connected with two electric energy metertail interfaces. The voltage input terminal and the current input terminal are connected with a metering loop. By arranging the electric energy meter binding posts corresponding to the positions of the meter position wiring ports of the intelligent electric energy meter, the electric energy meter is directly plugged and fixed on the device through the binding posts, live replacement of the electric energy meter is achieved, repeated wiring is not needed, the operation is simple, and the safety in the live replacement process of the electric energy meter is ensured.

Description

technical field [0001] The present disclosure relates to related technical fields, and in particular, relates to an adapter device and a method for replacing an electric energy meter with electricity for uninterrupted measurement of electric energy meters. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] At present, with the popularization and replacement of smart energy meters, the operating cycle of smart energy meters is shortened, and power supply companies will replace the energy meters in operation from time to time to ensure the accuracy of energy metering and the expansion of related functions. As the secondary equipment of the electric energy metering system, the smart electric energy meter is usually replaced when the primary equipment is not powered off. [0004] The inventor finds that the following problems exist in the repl...

AI Technical Summary

Problems solved by technology

[0005] (1) Metering loss caused by non-measurement during the replacement process: the existing method uses the junction box for metering to short-circuit the current secondary circuit and disconnect the voltage secondary circuit to ensure the safety of people and equipment during the replacement process of the electric energy meter. Safety, due to the short-circuit of the current secondary circuit and the disconnection of the voltage secondary circuit during the replacement process, the electric energy meter cannot be measured during the replacement process, forming a "electric energy measurement gap", which does not meet the continuity requirements of electric energy measurement, causing electric energy Measurement loss

[0006] (2) Using the existing method to achieve seamless measurement, the operation is cumbersome during the replacement process, and the new meter and the old meter need to be connected and disconnected many times, which is easy to make mistakes and has poor security
