Electric energy meter wiring protection device capable of improving safety performance

Abstract

The invention discloses an electric energy meter wiring protection device capable of improving safety performance, and the device comprises a box body which is of a cavity structure, wherein the cavity structure is used for installing an electric energy meter, the cavity structure is internally provided with a wire inlet port connected with an input power supply, the box body is provided with an opening, and the box body at two sides of the opening is provided with a protection door in an opening and closing manner; an opening and closing part which is arranged at the opening and closing end of the protective door, and provided with a clamping space; and an electromagnet which is fixedly arranged at the opening and closing end of the box body, wherein the opening and closing part is rotated, the electromagnet is clamped in the clamping space or separated from the clamping space, so that the protective door is closed or opened, and the electromagnet is conductively connected with the wire inlet port; the electromagnet conducts electricity so that the electromagnet can generate magnetic attraction force on the opening and closing part, and the opening and closing part is fixedly attracted to the electromagnet. According to the electric energy meter wiring protection device, when the input power supply is in the on state, the electromagnet conducts electricity, so that a worker cannot open the protection door by rotating the opening and closing part, and the safety performance of electric energy meter wiring work is improved.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to an electric energy meter wiring protection device for improving safety performance. Background technique [0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric meter, a fire meter, or a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities.
