Description

In one kind, pressure three-core cable single-phase fault repairs connecting tube
Technical field
The utility model is related to electrical equipment technical field, more particularly to presses the reparation of three-core cable single-phase fault to connect in one kind Adapter.
Background technology
Cable connection tube is the conductive gold utensil for connecting adjacent two conductors in circuit, and which can guarantee that electric current passes through, and have Certain pulling force.
Cable occurs to produce electric arc over the ground during earth fault, and temperature is higher, causes insulating barrier Albation melting, copper line The adverse consequences such as core is damaged, the minimizing of core length, and then docking in situ cannot be completed.Due to the working voltage of high-tension cable very high (usually 35kV-10kV), and electric field is complicated, therefore for the general restorative procedure of failure removes failure cable section for saw, then One section of cable is rejoined, this method connects twice due to needing to do, and waste is larger, and repair time is also longer;Three-core cable Single-phase fault be one of most commonly seen failure in cable operation, therefore, solve the problems, such as which is repaired and just can solve major part Cable fault.
Utility model content
The purpose of this utility model is to provide pressure three-core cable single-phase fault in one kind and repairs connecting tube.
For this purpose, technical solutions of the utility model are as follows:
In one kind, pressure three-core cable single-phase fault repairs connecting tube, including:Aluminium hydraulic pressed connecting pipe main body and repairing structure;
Wherein, aluminium hydraulic pressed connecting pipe main body is hollow tubular structure;
Repair structure to be made up of two blocks of orthogonal plates, the width of two boards is equal with the internal diameter of aluminium hydraulic pressed connecting pipe main body;Two Center line of the block plate through width each other, forms decussate texture;Repair structure to be fixed in the middle part of the inwall of aluminium hydraulic pressed connecting pipe main body, Decussate texture is made along the radial distribution of aluminium hydraulic pressed connecting pipe main body.
Preferably, the length for repairing the two boards of structure is 10-20mm, and thickness is 2-3mm.
Compared with prior art, the middle pressure three-core cable single-phase fault that the utility model is provided is repaired connecting tube and solves copper The matter core core length that often breakage is melted and caused is reduced, it is impossible to the problem of docking in situ;The ten of aluminium hydraulic pressed connecting pipe body interior Font is repaired structure and be can guarantee that in the case of contact resistance, it is to avoid electric current produces kelvin effect, connects pressure request so as to both meet The consumption of material-saving again.
In addition, repair connecting tube using middle pressure three-core cable single-phase fault of the present utility model can be after damaged core be removed In-situ immobilization is carried out, greatly reduces the time of reparation, save repair materials, the mechanical performance after reparation meets operation demand, electricity Resistance rate and common adapter no significant difference, install simply, there are professional standards without the need for operating personnel, and promotion prospect is considerable.
Description of the drawings
Fig. 1 is the top view that middle pressure three-core cable single-phase fault of the present utility model repairs connecting tube.
Fig. 2 is the side cutaway view that middle pressure three-core cable single-phase fault of the present utility model repairs connecting tube.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to the utility model, but following embodiments are right absolutely not The utility model has any restriction.
As shown in Figure 1-2, in this, pressure three-core cable single-phase fault reparation connecting tube includes:Aluminium hydraulic pressed connecting pipe main body 1 and repairing knot Structure 2;
Wherein, aluminium hydraulic pressed connecting pipe main body 1 is hollow tubular structure;Choose copper connecting tube of hardness HB less than 65 after annealing, and table Face is smooth, impulse- free robustness, crackle and sharp edge;The material of aluminium hydraulic pressed connecting pipe main body 1 is obtained after electroplating surfaces with tin process;According to different size Aluminium hydraulic pressed connecting pipe main body 1 can be fabricated to different sizes to adapt to use by the area of section of cable core.
Repair structure 2 to be made up of two blocks of orthogonal plates, the width of two boards is equal with the internal diameter of aluminium hydraulic pressed connecting pipe main body 1; Center line of the two boards through width each other, forms decussate texture;Repair the inwall that structure 2 is fixed on aluminium hydraulic pressed connecting pipe main body 1 Middle part, makes decussate texture along the radial distribution of aluminium hydraulic pressed connecting pipe main body 1.
The length for repairing the two boards of structure 2 is 10-20mm, and thickness is 2-3mm.
Now the using method that middle pressure three-core cable single-phase fault of the present utility model repairs connecting tube is described below:
First, staff presses the failure phase of three-core cable from middle removal, retains the single-phase portion that two ends are not damaged Point;Then stripping copper shield, semi-conductive layer and insulating barrier, expose conductor part;With middle pressure three-core cable of the present utility model Single-phase fault repairs connecting tube connecting conductor point, and specially the inner chamber by two sections of conductor parts respectively from aluminium hydraulic pressed connecting pipe main body 1 is inserted Enter, until the decussate texture of structure 2 is repaired in contact, so as to ensure the resistivity and mechanical strength of conductor connection.This practicality is new The middle pressure three-core cable single-phase fault of type is repaired connecting tube and solves the copper core core length that often breakage is melted and caused Reduce, it is impossible to the problem of docking in situ;The cross of aluminium hydraulic pressed connecting pipe body interior is repaired structure and can guarantee that the situation in contact resistance Under, it is to avoid electric current produces kelvin effect, connects pressure request but also the consumption of material-saving so as to not only meet.
In addition, repair connecting tube using middle pressure three-core cable single-phase fault of the present utility model can be after damaged core be removed In-situ immobilization is carried out, greatly reduces the time of reparation, save repair materials, the mechanical performance after reparation meets operation demand, electricity Resistance rate and common adapter no significant difference, install simply, there are professional standards without the need for operating personnel, and promotion prospect is considerable.
