Electric energy measuring instrument cabinet

Abstract

The invention, which belongs to the electric energy metering field, discloses an electric energy metering instrument cabinet comprising a metering instrument cabinet, the left end of the metering instrument cabinet is fixedly provided with a ventilation dustproof net, the left inner wall of the metering instrument cabinet is symmetrically and fixedly provided with guiding slide rails, and the sides, close to each other, of the two guiding slide rails are provided with guiding slide grooves. A self-cleaning wind power box and a power production assembly are additionally arranged in the measuring instrument cabinet to be used in cooperation, so that dust accumulated on the surface of a ventilation dustproof net can be cleaned in time, smooth ventilation in the measuring instrument cabinet is effectively kept, temperature balance in the measuring instrument cabinet is further kept, and the measuring instrument cabinet is convenient to use. And continuous and normal use of equipment in the measuring instrument cabinet is facilitated, the cleaning area of the self-cleaning wind power box is enlarged through use of the heating driving assembly, and the dust removal effect is further improved.

Description

technical field [0001] The invention relates to the field of electric energy metering, and more specifically relates to an electric energy metering appliance cabinet. Background technique [0002] Electric energy metering device is a metering instrument used to measure and record power generation, power supply, plant power consumption, line loss power and user power consumption. Electric energy metering device refers to an electric energy meter (active and reactive energy meter, maximum demand meter, multi-rate electric energy meter, etc.), metering transformers (including voltage transformers and current transformers) and secondary connecting wires. overall. [0003] With the continuous development and extension of underground coal mines, the underground power supply network of coal mines is becoming more and more complex. The more complex the power supply network, the greater the demand for electric energy metering equipment. The underground environment of coal mines is ...

AI Technical Summary

Problems solved by technology

[0004] The use of electric energy metering equipment is generally concentrated in the installation cabinet, and the ventilation of the installation cabinet must be maintained at the same time. At this time, there will be a need for dust prevention during the ventilation process. The combination of dust-proof net and manual regular cleaning is time-consuming and labor-intensive. Due to the complex environment under the mine and a lot of dust, if the dust-proof net is not cleaned in time, the heat dissipation capacity of the equipment will drop sharply, resulting in excessive board temperature. High, working abnormally
