Abstract

An insulated package casing relates to the field of circuit maintenance. The structure is as follows: the two ends of a package casing (2) are of the same outer diameter, the inner diameter of the package casing (2) is cone-shaped, and an inner diameter A (1) is larger than an inner diameter B (3). The package casing (2) is made of insulating materials including polyethylene, polypropylene, rubber and the like. The package casing (2) is used for being connected with a package insulating layer of a secondary terminal line. The insulated package casing of the invention has the following beneficial effects: first, the working time for previous insulated package of a secondary terminal line is reduced by 2/3; second, the problem that a terminal line may be wrapped unreliably is solved; third, an absolute insulation safety effect is achieved; fourth, the package requirements of wiring terminals of two specifications are met; and fifth, the package casing can be made in different colors to play a role in distinguishing voltage and current identification.

Description

The coated sleeve pipe of a kind of insulation

one, technical field

The present invention relates to maintenance circuit field, particularly one insulate coated sleeve pipe.

two, background technology

At present, in substation equipment operation maintenance process, secondary device regular inspection, disconnect secondary terminals line and become at every turn a requisite job, all safe insulation measure must be carried out after most binding post removes, because binding post can be likely electriferous state, or naked leakage part is rocked and is touched other live terminal and may cause short circuit, maintenance personal is leak naked the effect that insulation is afford to live in part wrapping with insulating tape to the binding post removed, in the long-term course of work, this wrapping work usually can not accomplish that insulation is very reliable, also more time-consuming, unreliable by insulating tape wrap insulate, the situation that parcel is not tight is there is at the long middle occasional of parcel, secondary line terminal naked leakage part majority is spininess simultaneously, be easy to puncture insulating tape,

Compare by adhesive tape encapsulation process and waste time and energy, consume material.

three, summary of the invention

The invention provides the coated sleeve pipe of a kind of insulation for the problems referred to above, its structure is: coated sleeve pipe (2) outer in the same size through two ends, through tapered in coated sleeve pipe (2), interior through A(1) be greater than interior through B(3).

Described coated sleeve pipe (2) is made up of insulating material, and insulating material is: polyethylene, polypropylene, the materials such as rubber.

Described coated sleeve pipe (2) is for connecing the coated insulating barrier of secondary terminals line.

The present invention uses like this: in substation equipment operation maintenance process, secondary device regular inspection, take secondary terminals line apart, coated sleeve pipe (2) is enclosed within the secondary terminals line taken apart, during socket, the end of a thread first passes the interior through B(3 of coated sleeve pipe (2)), interior through A(1 again from coated sleeve pipe (2)) pass, after waiting the secondary terminals line taken apart to connect, coated sleeve pipe (2) is shifted onto and the end of a thread of overlap joint can be wrapped up completely and can finish the work.

Beneficial effect of the present invention is: 1, the coated operating time of secondary terminals line insulation in the past will save 2/3rds; 2, solve terminal line and likely wrap up insecure situation; 3, absolute insulation safety effect is played; 4, the coated requirement of transformer station's two kinds of specification binding posts is met; 5, coated sleeve pipe is made different colours and can play voltage, the effect of electric current distinguishing identifier.

five, embodiment

Embodiment 1, the coated sleeve pipe of a kind of insulation, its structure is: coated sleeve pipe (2) outer in the same size through two ends, through tapered in coated sleeve pipe (2), interior through A(1) be greater than interior through B(3).

Claims

1. insulate a coated sleeve pipe, it is characterized in that: coated sleeve pipe (2) outer in the same size through two ends, through tapered in coated sleeve pipe (2), interior through A(1) be greater than interior through B(3).
