Switching device for live replacement of electric energy meter for uninterrupted measurement and method for replacing electric energy meter

Abstract

This disclosure proposes an adapter device and a method for replacing electric energy meters with live electricity for uninterrupted measurement. Safety and continuity of energy metering during energy meter replacement. The switching device includes a shell, a voltage input terminal, a current input terminal and a terminal post of the electric energy meter connected to at least two electric energy meter tail interfaces; the voltage input terminal and the current input terminal are connected to the metering circuit. The terminal of the electric energy meter corresponding to the position of the terminal of the smart electric energy meter is directly fixed on the device by plugging and unplugging the electric energy meter through the terminal, so as to realize the live replacement of the electric energy meter without repeated wiring, and the operation is simple to ensure the replacement of electric energy when the electric energy is charged. Security in table procedures.

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
