Heat dissipation window cleaning assembly for metering box

Abstract

The invention provides a heat dissipation window cleaning assembly for a metering box, and relates to the field of ammeters. The heat dissipation window cleaning assembly comprises a housing, a heat dissipation window arranged on the side surface of the housing, at least one heat dissipation hole, an exhaust fan fixed in the heat dissipation hole, exhaust pipes in one-to-one correspondence with the heat dissipation holes, second fixing blocks, second partition plates and driving parts, wherein each exhaust pipe comprises a front port and a rear port, the front ports are located outside the shell and communicate with the heat dissipation holes, and the rear ports penetrate through the shell and extend into the shell; the second fixing blocks are fixed on the inner side surface of the shell and are in one-to-one correspondence with the heat dissipation holes; a plurality of second through holes are formed in the second partition plates, the rear ports are fixed to the right side faces of the second partition plates, and the second through holes are communicated with the rear ports; and the driving parts are arranged in the shell, are in one-to-one correspondence with the second partition plates and are used for driving the second partition plates to be far away from or close to the second fixing blocks. According to the heat dissipation window cleaning assembly, when a large amount of dust is adhered to the heat dissipation window, the heat dissipation window can be cleaned in time, so that components in the metering box are kept to operate at a normal temperature.

Description

Technical field[0001]The present invention relates to the field of electricity, and more particularly to a heat dissipation window cleaning assembly for a measuring box.Background technique[0002]The power meter is a device for electric energy meter in 3kV-35KV, including combined transformers, boxes, electric meter, arresters, vacuum circuit breakers, etc., current accuracy is 0.2 s, voltage accuracy is 0.2, meter The box is a widely used power metering device. Due to the operation of the various components in the measuring box, a large amount of heat is generated, which is generally through the heat dissipation window.[0003]The Applicant has found that when the cooling window is too long, there will be a large amount of dust adhesion, so it will cause heat dissipation.Inventive content[0004]In view of this, an object of one or more embodiments of the present specification is to propose a heat dissipation window cleaning assembly for measuring box to solve a large amount of dust adh...
