Button cover assembly for high voltage ring main unit operation panel

Abstract

The invention provides a button cover assembly for a high voltage ring main unit operation panel. The button cover assembly comprises a button cover, a base, a button shaft and a button spring. The button cover comprises a button cap and two supporting blocks, the two supporting blocks are fixed to one side of the button cap, the button spring is installed between the two supporting blocks, the base comprises a U-shaped supporting plate and a back plate fixed to one side of the U-shaped supporting plate, an installation component is arranged on the back plate and used for installing the button cover assembly to the high voltage ring main unit operation panel, the button spring is provided with a button spring hole, the button shaft penetrates through an installation hole, a circular hole and the button spring hole in sequence, the first end of the button spring abuts against the button cover, and the second end of the button spring abuts against the base. The button cover assembly for the high voltage ring main unit operation panel has the advantages that rainwater, dust and insects are prevented from entering a device, and the button cover can be locked.

Description

technical field [0001] The invention relates to a button cover, in particular to a button cover assembly used for the operation panel of a high-voltage ring network cabinet. Background technique [0002] The control panel of the small high-voltage ring network cabinet plays the role of control, status indication and protection in the whole switch cabinet. At present, the operating holes of the control panels of most small high-voltage ring network cabinets are not installed and used with button covers, which will directly expose the operating holes, and rain, dust, insects, etc. from the outside will enter the inside of the switchgear for a long time and damage the switchgear. The normal operation of the switchgear shortens the service life of the equipment and brings safety hazards to production and life. Failure to install and use the button cover will also make those non-professionals touch and operate these switchgears, which will destroy the normal power supply of the ...

AI Technical Summary

Problems solved by technology

At present, the operating holes of the control panels of most small high-voltage ring network cabinets are not installed and used with button covers, which will directly expose the operating holes, and rain, dust, insects, etc. from the outside will enter the inside of the switchgear for a long time and damage the switchgear. The normal operation of the switchgear shortens the service life of the equipment and brings safety hazards to production and life

Failure to install and use the button cover will also make those non-professionals touch and operate these switchgears, which will destroy the normal power supply of the switchgear and affect the production and life of users

Wrong operation of the switchgear will also cause loss to the user's property and even endanger the life of the person

[0003] There are also a small number of switchgears on the market equipped with button covers. There are two main types of these button covers: one is the threaded type, which connects the button cover and the panel with threads, but this kind of device is inconvenient to disassemble and needs to be disassembled before each operation. , it needs to be reinstalled after the operation is completed, and it is easy to be damaged during the disassembly process, so it is not suitable for occasions with frequent operations; the other is to use a steel plate to cover, this method overcomes the problem of inconvenient disassembly and assembly of the button, and can also be repeated used, but cannot locate

When operating, one hand is required to fix the button cover, and the other hand is used to operate, and the production is complicated and the cost is high

These two kinds of button covers simply cover the operation holes of these panels, and the operation holes cannot be locked with the button covers, so that non-professionals cannot be prevented from touching and operating these switchgears, which has certain potential safety hazards.
