Abstract
The invention discloses a secondary cable carrot joint capable of thermally shrinking directly. The secondary cable carrot joint is composed of a cable carrot joint main body and a thermally-shrinking overskirt, wherein the cable carrot joint main body is made of a thermally-shrinking material or soft plastics having certain elasticity and is cylindrical, and a wire inlet hole is formed axially at the center of the cable carrot joint main body; the thermally-shrinking overskirt is made of a thermally-shrinking material and is of a circular skirt shape (i.e., a cone shape); the wire inlet hole is of a shape of an outer contour of the integral cross section of a corresponding cable core, and the size of the outline of the hole is slightly less than the size of the outer contour of the corresponding cable core. The secondary cable carrot joint can be conveniently sheathed on the cutting end part of the cable, then is subjected to thermal shrinkage by a heat gun, and can be well fixed at the cable cutting end part after thermal shrinkage, the operation is simple, and inconsistent or inaesthetic appearance caused by the technological level of operators can be avoided; the cable carrot joint main body and the thermally-shrinking overskirt are of an integral structure, the outline of the diameter of the wire inlet hole can be well matched with the outer outline of the corresponding cable core, and the leakproofness is greatly improved.
Description
Technical field
The present invention relates to Protection Technology and field of cables, specifically a kind of can the secondary cable peckled turnip of direct pyrocondensation.
Background technology
Along with the development of power system, Protection Technology plays an important role in power system. It is frequently necessary to secondary cable end is carried out insulating barrier cutting process in relay protection works; to stay the secondary cable core of sufficient length for secondary connection; at cable cutting tip it is generally required to carry out end portion treatment; in case after cable end cutting, inside its insulating barrier, armor burr is exposed injures secondary wire core and operating personnel; simultaneously work as certain sealing function; prevent moisture etc. from entering etching insulating layer armor, additionally ensure that the neat, attractive in appearance of cable end. Current end portion treating method generally adopts the mode of winding that at the secondary cable core outer wall being close to cable cutting tip insulating tape is wound around some circles, and the heat-shrink tube putting sufficient length when thickness to be wound and the outside diameter of cable are almost consistent again carries out pyrocondensation process. Using the end that this technique is produced to present " Radix Raphani " head ring lines, cable core, just as the leaf of Radix Raphani, is referred to as " cable peckled turnip " habitually work of transformer substation field operation personnel. This method has the disadvantage in that 1, be wound around insulating tape compares and expends time in; 2, its processing quality has much relations with the operating technology level of operating personnel. 3, owing to the space between insulating tape and secondary wire core is bigger, between insulating tape and pyrocondensation tube wall, the relation due to technique also likely to be present gap, its sealing is relatively poor, there may be moisture etc. for a long time and enters insulating barrier corrosion armor, affects cable overall performance.
Summary of the invention
After cable end secondary wire core outer wall after being wound around cutting for using insulating tape in above-mentioned prior art, the reusable heat draw carries out the shortcoming existed in the method for pyrocondensation process, it is an object of the invention to provide a kind of can the secondary cable peckled turnip of direct pyrocondensation, it can be enclosed within cable cutting tip easily, reusable heat air pressure gun carries out pyrocondensation, just can be well fixed on cable cutting tip after pyrocondensation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of can the secondary cable peckled turnip of direct pyrocondensation, it is characterized in that, including cable peckled turnip main body, pyrocondensation suit of skirt;
Described cable peckled turnip main body is material contracting with heat or has certain elastic flexible plastic and make;
Described peckled turnip main body, it is column type, its central axial entrance hole that is provided with, and described pyrocondensation suit of skirt side is inlet wire side, and the inlet wire side of entrance hole is provided with inlet wire and deters chamfering;
Described entrance hole shape presents corresponding cable core global sections outer contour shape, and its hole overall dimensions is slightly less than the cable core outer profile size of correspondence.
Described pyrocondensation suit of skirt is that material contracting with heat is made, and it presents annular skirt (i.e. vertebral body shape), and adjacent cable peckled turnip body side is skirt waist, and opposite side is at the bottom of skirt.
The invention has the beneficial effects as follows:
1, the present invention can be nested with directly through cable core and carry out pyrocondensation fastening at secondary cable cutting tip, simple to operate, saves the time.
2, present invention, avoiding because the former outward appearance thus resulted in of operating personnel's technical merit is inconsistent or inaesthetic problem.
3, the cable peckled turnip main body of the present invention and pyrocondensation suit of skirt are overall structure, and entrance hole profile coincide very well with corresponding cable core outline, substantially increases sealing property.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the present invention provide a kind of can the secondary cable peckled turnip of direct pyrocondensation, it is characterized in that, including peckled turnip main body 1, pyrocondensation suit of skirt 2.
As in figure 2 it is shown, described peckled turnip main body 1 is overall in column type, its central axial entrance hole 7 that is provided with, the inlet wire side of entrance hole 7 is provided with inlet wire and deters chamfering 6;
Described entrance hole 7 shape presents corresponding cable core global sections outer contour shape, and its hole overall dimensions is slightly less than the cable core outer profile size of correspondence.
Described pyrocondensation suit of skirt 2 is made for material contracting with heat, and it presents annular skirt (i.e. vertebral body shape), and adjacent cable peckled turnip main body 1 side is skirt waist, and opposite side is at the bottom of skirt.
