Abstract

The utility model discloses a repair platform of an isolating switch, comprising an upper operating platform arranged on an upper bracket and a lower operating platform arranged on a lower bracket. A static contact dismantling frame is arranged at one end of the upper operating platform; an adjustment stable platform and a corresponding spring pressing device are arranged at the other end of the upper operating platform; an upper contact fixed block base is arranged in the middle of the upper operating platform; and the lower operating platform is provided with opening holes enabling rotation at the lower part of the isolating switch. The repair platform greatly improves the working efficiency and solves the problem that the isolating switch is difficult to be fixed, disassembled, assembled and debugged in the construction site.

Description

Isolation switch maintenance platform

Technical field:

The utility model relates to a maintenance device, in particular to the maintenance of GW16/17 series isolating switches in substations in the electric power industry.

Background technique:

With the continuous development of the power system, the GW16/17 isolating switches widely used in substations have successively reached the maintenance deadline. The installation is very troublesome, resulting in time-consuming and laborious maintenance. According to statistics, it takes 6 workers 2 to 3 days to complete the maintenance of a group of this type of isolating switch. This not only greatly prolongs the power outage time of the equipment, reduces work efficiency, but also increases the power supply. Loss, reducing the reliability and safety of power transmission and transformation equipment.

Utility model content:

The technical problem to be solved by the utility model is to provide an isolating switch maintenance platform for the above deficiencies. Disassembly, assembly, commissioning and other links, using compression springs, pressing and fixing, etc., through the reasonable configuration of each disassembly and fixing components, so as to achieve the purpose of quick maintenance of the isolation switch.

The technical scheme that the utility model takes is:

An isolating switch maintenance platform, including an upper workbench set on an upper support and a lower workbench set on a lower support, one end of the upper workbench is provided with a static contact dismantling frame, and the other end of the upper workbench is provided with an adjustment and stabilization The platform and the corresponding spring pressing device, the middle part of the upper worktable is provided with an upper contact fixing holder, and the lower workbench has an opening that can rotate the lower part of the disconnector.

For the convenience of moving and fixing, four lockable universal wheels are provided at the bottom of the upper bracket.

In order to facilitate the various links of fixation, disassembly, assembly and debugging, the lower bracket is arranged on the slideway, so that the lower workbench can be pulled under the upper workbench.

The lower bracket also has an adjustment piece that can adjust the height up and down.

Fixing holes are arranged around the opening for bolt fixing.

The utility model greatly improves the working efficiency, and solves the problems of difficulty in fixing, disassembling, assembling and debugging the isolating switch at the construction site.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

FIG. 2 is a schematic top view of the structure of FIG. 1 .

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1 and 2, the isolating switch maintenance platform includes an upper workbench 6 set on the upper support 2 and a lower workbench 5 set on the lower support 3. The upper workbench 6 and the lower workbench 5 have the same structure. It is a rectangular steel plate, and the upper workbench 6 is designed and installed with four parts, which are respectively the static contact removal frame 7, the upper contact fixing card seat 10, the adjustment and stability platform 8 and the spring pressing device 9; the lower workbench 5 has four parts The 12 fixing holes are used for bolt fixing, the central opening 11 is used for the rotation of the lower part of the isolating switch, the lower bracket 3 is set on the slideway, and the lower workbench 5 is unfolded through the slideway during use, and the height is adjusted by the adjustment part 4 to make it appropriate And stable, the upper support 2 is equipped with four lockable universal wheels 1, which are locked during use to prevent it from moving. During the inspection and maintenance process, the upper workbench 6 is mainly used for inspection and assembly of the upper and lower conductive rods of the GW16/17 series isolating switch, the static contact and the moving contact of the grounding isolating switch, etc., and the lower workbench 5 is mainly used for placing the overhauled Components and various consumables, tools, spare parts, etc. During debugging, the assembled isolating switch can be fixed on the lower workbench 5, and the state of the isolating switch can be adjusted by standing on the platform and manually opening and closing the isolating switch. After the commissioning is completed, the isolating switch that has been overhauled can be transported to the designated location through the overhaul platform for hoisting.
