Bare cable isolation sleeve

Abstract

The invention belongs to the field of a power distribution tool and particularly relates to a bare cable isolation sleeve. The bare cable isolation sleeve has the characteristics of simple, practicaland convenient structure and good isolation effect; meanwhile, the isolation sleeve can be freely combined on the basis of existing single use so as to meet more and more complex working contents; invarious different use environments, working efficiency can be improved; the scheme is low in cost; the bare cable isolation sleeve not only has a passive isolation effect, but also can be further expanded to have active protecting and alarming effects, so that a use effect of the isolation sleeve is further improved, and use occasions of the bare cable isolation sleeve are expanded; a combined structure of the bare cable isolation sleeve can conveniently and rapidly achieve a neat and uniform board effect and consistency of working contents is improved; and the bare cable isolation sleeve hasa promoting effect on normalization and integration on various works of power distribution operation and the like.

Description

technical field [0001] The invention belongs to the field of power distribution tools, in particular to a bare cable isolation sleeve. Background technique [0002] In the process of power distribution work and equipment installation and commissioning, a large number of cables / wires need to be lapped. Usually, the equipment needs to go through a specific test and inspection process before use to confirm the equipment, lines and various accessories. Or the structure is installed correctly to ensure the safe and stable operation of the equipment. Therefore, after the equipment is installed and fixed and the lines are connected, a power-on test is required. For a small number of equipment with simple structure, easy installation or high integrity, most of the internal structures have been fixed, so it is generally judged by testing the operation performance of the equipment by electrifying the whole machine, but for most equipment , usually involves multiple cooperative mechan...

AI Technical Summary

Problems solved by technology

For a small number of equipment with simple structure, easy installation or high integrity, most of the internal structures have been fixed, so it is generally judged by testing the operation performance of the equipment by electrifying the whole machine, but for most equipment , usually involves multiple cooperative mechanisms, and the connection relationship between each structure and each structure is relatively complicated. Direct power-on testing of the whole machine may lead to unpredictable results, especially for large-scale machinery. At the same time, it is difficult to accurately and quickly confirm the internal structure of the structure. Therefore, in the actual test and inspection process, it is often used to detect the lines and nodes in the equipment. By testing the current in the lines or nodes and the state of the control signal, it is judged whether the line is normal and the control system is normal. In the process of daily use and maintenance, it is often necessary to disassemble and overhaul the equipment or machinery or part of its structure

During maintenance or testing, it is necessary to remove the cable or node to be tested from the socket or connection for testing. In the case of a large number of cables, it is often easy to confuse. Since some cables may be charged, the cable When densely placed, it may cause electricity leakage, which will cause hidden dangers to the safety of operators and equipment. At the same time, due to the similar color of the cable structure, it is easy to confuse when the number is large, and it is impossible to distinguish the connection relationship between each other. efficiency
