Power cut and electricity quantity loss preventing electric energy meter replacing apparatus

Abstract

The invention relates to a power cut and electricity quantity loss preventing electric energy meter replacing apparatus comprising a live wire connect-in unit, a live wire connect-out unit, a zero wire connect-in unit and a zero wire connect-out unit. The power cut and electricity quantity loss preventing electric energy meter replacing apparatus is characterized in that each of the live wire connect-in unit, the live wire connect-out unit, the zero wire connect-in unit and the zero wire connect-out unit respectively comprises an electric conduction drainage seat, an electric conduction positioning seat arranged above the electric conduction drainage seat, an electric conduction support rack arranged above the electric conduction positioning seat, and an electric conduction roller arrangedon the electric conduction support rack; a circumferential surface of the electric conduction roller is provided with four radial through holes, a bottom face of the electric conduction support rackis provided with vertical through holes corresponding to the radial through holes, vertical slots communicated with the vertical through holes are arranged in the electric conduction positioning seat,and a bottom face of the electric conduction drainage seat is provided with a wire cable plug-in opening. The power cut and electricity quantity loss preventing electric energy meter replacing apparatus is simple in structure and reliable in use; continuous electricity consumption of users can be prevented from being affected, power consumption quantity metering work conducted by power supply enterprises can be prevented from being affected in meter replacing processes, convenience can be brought to the users, economic loss of the power supply enterprises can be greatly reduced, and work efficiency and service quality can be markedly improved.

Description

technical field [0001] The invention relates to an electric energy meter installation accessory, in particular to an electric energy meter replacement device without power failure and power loss. Background technique [0002] A watt-hour meter is an instrument used to measure electric energy, also known as a watt-hour meter. During the operation of the energy meter, there will be failures, application for calibration, regular rotation and other situations that require replacement of the energy meter. [0003] The replacement of the current resident electric energy meter needs to be operated after the power outage of the resident user, which will cause the periodic power outage of the resident user and affect the normal life. Moreover, according to the "Business Rules for Power Supply and Utilization", residential users need to be notified 7 days in advance of a power outage. The methods of power outage notification include telephone notification, text message notification, ...

AI Technical Summary

Problems solved by technology

[0004] At this stage, there are also some non-power-off meter replacement devices. Its working principle is similar to the function of a joint junction box, and the electric energy meter can be replaced without power failure to the user. metered electricity consumption, resulting in a loss of electricity

Take Jinzhou area as an example: the number of residential users reaches 1.26 million. If the existing non-stop meter replacement device is used, and each household replaces the electric energy meter once, the accumulated power loss will bring huge economic losses to the power supply company.

Therefore, there are disadvantages in the existing electric energy meter replacement scheme, which needs to be improved urgently
