Built-in dustproof structure suitable for low-voltage switch cabinet

Abstract

The invention relates to the field of dust prevention of low-voltage switch cabinets, in particular to a built-in dust prevention structure suitable for a low-voltage switch cabinet, which comprises a main body, a dustproof mechanism, an opening and closing mechanism, a lifting mechanism, a folding mechanism and an auxiliary mechanism, and through the arrangement of the dustproof mechanism, a dust filtering effect can be achieved while the main body is cooled, a dustproof component can be detached and cleaned without opening the main body, normal operation of the main body is guaranteed, through the arrangement of the auxiliary mechanism, the dustproof component is conveniently detached and replaced, the use effect of the main body is improved, and the practicability is high. By arranging the lifting mechanism, a moving part can extend to the bottom end of the main body, so that the main body can be conveniently moved in a labor-saving manner, by arranging the folding mechanism, the moving part in the lifting mechanism can be conveniently rotated, the occupied space is reduced through the design of a folding crank, and the usable space of the main body is increased; and the folding mechanism is convenient to unfold through the arrangement of the opening and closing mechanism, the folding mechanism can be prevented from being exposed to the outside, and the attractiveness of the main body is improved.

Description

technical field [0001] The invention relates to the dust-proof field of low-voltage switch cabinets, in particular to a built-in dust-proof structure suitable for low-voltage switch cabinets. Background technique [0002] Low-voltage switchgear is suitable for power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries, as power transmission, power distribution and power conversion. The product complies with the standard of GB7251.1-2013 "Low Voltage Complete Switchgear" (IDT IEC60439-1 1999). Low-voltage switchgear is a product listed in the "Catalogue" of 3C certification compulsory certification products. It can meet the requirement that each electrical component can be reliably fixed in a determined position in the cabinet. The shape of the cabinet is generally a cube, such as a screen type, a box type, etc., and there are also prisms such as a table type. This kind of cabinet has single row and arrangement.

AI Technical Summary

Problems solved by technology

[0003] Low-voltage switchgear is divided into fixed type and withdrawable type according to the structure. Since there are many electronic components inside the low-voltage switchgear, it will generate a lot of heat during use, so it needs to be considered for the switchgear at the beginning of design. For heat dissipation, it is difficult to prevent dust from entering the inside of the switchgear after opening the heat dissipation holes. The traditional switchgear method is to fix the dust filter parts on the heat dissipation holes. After a period of use, the dust will adhere to the non-removable filter parts. Affect the heat dissipation effect of the switchgear, and even cause the electrical components to burn
