Fast assembly and disassemble type cable protecting jacket

Abstract

The invention relates to a consumable item special for overhauling, and in particular relates to a fast assembly and disassembly type cable protecting jacket comprising a protecting jacket formed by two half pipes which are detachably buckled together, wherein the protecting jacket is made of OVC material, and an anticorrosive paint layer is arranged on the outer surface of the protecting jacket.According to the fast assembly and disassemble type cable protecting jacket provided by the invention, the problem that a flexible conduit of a damaged cable is difficult to change on the overhaulingscene is solved; the protecting jacket provided by the invention is simple in structure, convenient to install and unnecessary to disassemble the cable for change, so that required time of such work can be greatly reduced, a cable maintenance effect can be ensured while work efficiency is improved, and safe operation of outdoor power transformation equipment is ensured.

Description

technical field [0001] The invention relates to a special consumable for maintenance, in particular to a quickly detachable cable protective cover. Background technique [0002] A substation is a power facility in the power system that transforms voltage, receives and distributes electric energy, controls the flow of power, and adjusts voltage. It connects the power grids of all levels of voltage through its transformers. The equipment that transforms the voltage in the substation is a transformer. In addition, the equipment in the substation also includes switchgear for opening and closing circuits, busbars for collecting current, transformers for measurement and control, instruments, relay protection devices, and lightning protection devices. , dispatching communication devices, etc., and some substations also have reactive power compensation equipment. Except for the protection and measurement and control panel cabinets of each unit, as well as the low-voltage switchgear...

Problems solved by technology

Nowadays, a large number of metal-coated snakeskin tubes are used in substations, which have good anti-distortion and bending properties, can bear heavy loads, and play a good role in cable protection. However, when the equipment runs for a long time, especially It is more than 5 years of equipment. Due to the weathering and cracking of the outer plastic film of this kind of snake skin tube, the metal tube is exposed to the external complex environment for a long time to erode, resulting in severe corrosion and cracking in different parts, and the snake skin tube sleeve is loose and falls off. Rainwater flows in from the damaged part of the snake skin tube and gathers at the lowest point for long-term immersion, which will deteriorate the insulation of the cable and cause a short circuit, resulti
