Dustproof cover of power and electrical equipment component

Abstract

The invention discloses a dustproof cover of a power and electrical equipment component. The dustproof cover comprises a machine cabinet and a base; the base is mounted at the top end of the machine cabinet; a second sliding groove is formed in the top end of the interior of the base; first sleeves are arranged on the left and right sides of the top end of the base respectively; a first sliding block is mounted at the bottom end of each first sleeve; each first sliding block is lap jointed with a second sliding groove; and a second sliding block is mounted at the top end of each first sleeve.By virtue of the dustproof cover of the power and electrical equipment component, entering of dust into the machine cabinet can be avoided by virtue of matching of a pressing cover and a plug, so thatdust cleaning operation by a staff can be omitted; by virtue of matching of the second sliding block and the second sliding groove, influence to operation caused by falling off of a cable due to accidental collision by the staff can be prevented; and through matching of a second gasket and a second compression spring, a clamping block can be pushed to extend out of the first sleeves to cover thegap between the first sleeves, so that entering of dust to the interior of the machine cabinet can be prevented after the cable is connected, thereby satisfying customer demands.

Description

technical field [0001] The invention relates to the technical field of dustproof covers, in particular to a dustproof cover for components of electric power equipment. Background technique [0002] In the existing designs of gas-insulated switches and power transformers in electric power equipment, it takes a period of time before they are energized after they are assembled. During this period, related electrical components such as the opening of the cable fixing seat are exposed to the air, and the dust on the ground will fly around due to the work of the staff. In addition, factors such as dust in the air make the cable fixing seat go through a period After a period of time, a lot of dust will adhere to the inside of the surface of the opening. Therefore, the operator must spend a period of time cleaning before inserting the cable, which will greatly reduce the work efficiency and waste time. For example, the patent application number 201520102623.X includes a dust cover ...

AI Technical Summary

Problems solved by technology

Therefore, the operator must spend a period of time cleaning before inserting the cable, which will greatly reduce the work efficiency and waste time. For example, the patent application number 201520102623. The main body of the dust cover is arranged on an opening of a related component of electric power equipment opposite to an opening. Before the cable is installed, the opening on the fixed base cannot be completely closed, and the opening cannot be completely closed effectively. The staff needs to clean up the cable before installing the cable, and the cable cannot be tightened and fixed after the cable is installed. If the staff accidentally touches it and falls it will affect the work, and when the cable is installed, there will be a small amount of gaps in the opening, and dust will enter the inside of the cabinet after a long time, requiring frequent maintenance and cleaning operations by the staff , which greatly increases the work intensity of the workers, making it inconvenient for the workers to operate the machine and unable to meet the needs of customers
