A gis wall safety bracket

Abstract

A GIS over-the-wall safety bracket, comprising a left casing and a right casing, between which a pipeline with GIS equipment is clamped, between the left casing and the right casing, the lower left A set of clamping mechanisms is respectively provided between the connecting plate and the lower right connecting plate. A baffle plate is installed on the left casing and the right casing. The shielding plate is made of aluminum-plastic board, and a layer of insulating rubber pad is pasted on the surface of the left and right housings. The bracket can be assembled on site and hoisted together with the equipment to simplify the installation process; the aluminum-plastic plate matching the size of the bracket is used as the sealing material, which greatly shortens the time for equipment maintenance, repair and replacement. Abandoning the use of cement sandstone as a sealing material eliminates the root cause of equipment corrosion; equipment maintenance, repair, and replacement do not need to break the wall blocked by cement sandstone, as long as the aluminum-plastic plate is removed, it can be easily operated.

Description

technical field [0001] The invention relates to the field of power supply equipment, in particular to a GIS wall safety bracket. Background technique [0002] GIS equipment is a kind of gas pure metal enclosed combined electrical equipment. It has the advantages of small footprint, small operation and maintenance workload, high reliability, and long service life. It has been widely used in the power system and is a guarantee for substations Very important equipment for proper functioning. SF6 gas is colorless and odorless under normal conditions, and has good insulation performance and arc extinguishing performance. Once the moisture in the atmosphere is soaked or the surface of the solid medium is damp, the electrical performance will be significantly reduced. The indoor space of SF6 equipment is relatively airtight. Once SF6 gas leaks, due to the extremely slow air circulation, toxic decomposition products are deposited in the room and are not easy to discharge. Death, b...

Problems solved by technology

The indoor space of SF6 equipment is relatively airtight. Once SF6 gas leaks, due to the extremely slow air circulation, toxic decomposition products are deposited in the room and are not easy to discharge. death and environmental pollution

[0003] Defects in GIS equipment are prone to collision damage during hoisting, which brings potential safety hazards; after sealing with cement, it is easy to corrode the equipment shell due to the characteristics of cement, causing air leakage and bringing potential safety hazards; equipment maintenance, repair, replacement It is necessary to demolish the wall from time to time, which is likely to cause secondary damage to the equipment; once SF6 gas leaks from the part of the wall-penetrating equipment, it is difficult to find and deal with it in time
