Description

A portable high-voltage isolating switch maintenance workbench

technical field

The utility model relates to a substation inspection and maintenance work tool, in particular to a portable high-voltage isolating switch inspection and maintenance workbench.

Background technique

The isolating switch is the most widely used switching device in high-voltage power transmission and transformation. Most of the high-voltage isolating switches are installed outdoors and are directly affected by the environment. After a long time of operation, the conductive part will rust and oxidize and produce resistance. According to the resistance and temperature Relationship, the contact fingers will generate heat and deformation when they pass through a large current load. If the rotating parts are jammed or stuck during the operation, they may not fit properly and cause arc burns on the contact surface, and they will not be able to continue to operate, which will seriously affect the operation reliability of the substation equipment. In order to restore the isolating switch to The normal function required by the technical standard requires the disassembly and overhaul of the isolating switch.

With the continuous improvement of the level of substation maintenance work, the requirements for the quality of the maintenance process are becoming more and more stringent. When the disconnector is overhauled, the equipment should be disassembled and reassembled. The traditional method of dismantling and overhauling is to spread a piece of plastic cloth on the workplace, and the staff Squatting on the ground for dismantling, the work process is more labor-intensive, and dismantling on the spot has certain disadvantages, it is difficult to meet the process requirements, it is easy to cause unnecessary damage to the equipment, and affect the appearance and installation effect of the equipment.

Utility model content

The main purpose of the utility model is to overcome the shortcomings of the prior art, to provide a machine that can improve the maintenance work efficiency and process quality, effectively reduce the labor intensity of the staff, reduce the physical exertion of the on-site maintenance personnel, and has high stability, convenient use and convenience. Portable high-voltage isolating switch maintenance workbench.

The utility model adopts the following technical solutions:

A portable maintenance workbench for high-voltage isolating switches includes a foldable support and a worktable detachably arranged on the foldable support.

Further, the working surface forms a groove system fixture structure, and the surface is evenly distributed with positioning grooves for installing and fixing the isolating switch inspection fixture.

Further, the workbench is composed of two workbench boards detachably spliced together.

Further, the foldable support is composed of two mutually hinged upper frames, two lower supports respectively hinged on the two upper frames, and a support rod detachably connected between the two lower supports to support and fix the foldable support. The lower bracket is composed of two legs and a beam connected between the two legs, and the support rod is detachably connected between the beams of the two lower brackets.

Further, adjustable foot cups are threadedly connected to the bottom of the legs.

As can be seen from the above description of the utility model, compared with the prior art, the utility model has the following beneficial effects:

First, the collapsible bracket and detachable worktable are adopted, and the number of worktables required can be selected according to the size of the equipment, which occupies less space and is more convenient to carry;

Second, by setting adjustable foot cups, the height of the work surface can be adjusted, which can better meet the needs of the staff;

Third, the working surface forms a groove system fixture structure, which can facilitate the installation and disassembly of parts, and the fixture installation is more stable;

In a word, the utility model can improve the maintenance work efficiency and process quality, effectively reduce the labor intensity of the staff, reduce the physical exertion of the on-site maintenance personnel, and has high stability, convenient use and portability.
