Outdoor factory standard purification overhauling room

Abstract

The invention discloses an outdoor factory standard purification overhauling room which comprises an overhauling room top (1) and an overhauling room body (2). The overhauling room top (1) comprises a plurality of arched rib plates (101), and the rib plates (101) are placed on the overhauling room body (2) after the left sides and the right sides of the rib plates (101) are in lap joint with each other. The overhauling room body (2) comprises a side wall (202a) forming the room, a base plate (202b) and a top surface (202c). The top surface (202c) comprises a frame (3) with a hollow structure, a guide post (4) and a dustcloth (5). The guide post (4) is horizontally arranged on the frame (3), the dustcloth (5) can slide along the guide post (4), and a warning device (7) is arranged in the overhauling room body (2). Once a GIS device has faults, the device does not need to return to a factory to be maintained and can be dismantled and installed and overhauled on the site by building the outdoor factory standard purification overhauling room, and the power outage time is reduced.

Description

technical field [0001] The invention relates to the field of GIS equipment detection devices in electric power systems, in particular to an outdoor factory-like purification maintenance room. Background technique [0002] With the continuous development of my country's electric power industry, GIS combined electrical appliances are increasingly used in 220kV and above power grids. Because the conductive parts of GIS are all enclosed in the metal shell and insulated by SF6 gas, the risk of exposure of conductive parts of conventional open equipment to external influences such as the atmosphere is greatly reduced, and the reliability of equipment operation is effectively improved. However, it is also because of the fully enclosed feature that the importance of on-site assembly quality is more prominent. As we all know, due to the limitation of equipment transportation conditions, GIS and other large electrical equipment often need to be disassembled into different transportat...

AI Technical Summary

Problems solved by technology

Judging from the existing experience, this method has disadvantages: ① The weather conditions determine the construction progress, and it is difficult to strictly control the progress of the project. At the same time, the installation of GIS has requirements on the air humidity, and the installation quality is affected by the humidity. It can only be carried out on sunny days Operation

However, there is a lot of rain in the south of the Yangtze River. Taking Nanjing as an example, the annual precipitation days in Nanjing area are generally more than 100 days, and the construction period required to install a 220kV substation with 12 intervals of GIS is generally 72 days, and the probability of all sunny days during the entire construction period is less than 0.01%, which seriously affected the progress of the project

[0004] ②The installation environment affects the construction quality

[0005] ③It is not conducive to the development of maintenance work

[0007] In the existing technology, there is no standard maintenance room specially used for outdoor GIS factory. Now the traditional method is to directly carry out maintenance and installation in the outdoor natural environment. Once the GIS equipment fails, it needs to be returned to the factory for maintenance, which delays the repair time and installation time
