Abstract

The utility model provides a carbon fiber composite core conductor repair sleeve to repair the conductor when the carbon fiber composite core conductor is in damage or strand breakage in the power system. The repair sleeve is composed of a chamfer and an arc at two sides of an aluminum pipe and a gap arranged in axial direction and provided with a drawer anastomosed with the gap. When in installation, the carbon fiber composite core conductor is positioned inside the aluminum pipe through the drawer and is then crimped. In this way, the conductor can not only be better repaired, but also the holding power thereof can obviously be enhanced, which effectively improves the contact performance of the conductor, and also has the advantages of the simple structure, convenient use, firm contact, reliable performance, economy and practicality and being suitable for wide promotion.

Description

The carbon fiber composite core wire repair sleeve

Technical field:

This is practical to relate to the gold utensil that a kind of electric power system is studied for a second time courses one has flunked lead, particularly under damaged or disconnected strand situation takes place in lead, and the gold utensil that lead is studied for a second time courses one has flunked.

Background technology:

In electric power system overhead power line work progress, the outer aluminium thigh wearing and tearing of steel reinforced aluminium conductor often take place, fracture, in circuit regular meeting also time the in service because the external force damage produces the break phenomenon of thigh of disconnected strand and vibration.Must avoid broken lot to enlarge in this case, lead be carried out timely and suitable processing, otherwise will influence the normal operation of electric power system.The most general method is that the whippy helical form monofilament with prefabricated shaping is that preformed armor rods is studied for a second time courses one has flunked the outside that bar is wrapped in damage wires.This method is only applicable to damaged area and accounts for the less lead of aluminium thigh total area ratio, and accounting for the bigger lead of the aluminium thigh gross area for damaged area must cut off lead earlier, re-uses lead splicing sleeve and continues.So not only wasted time and energy but also waste material and fund.Moreover, because the electric power system electric network reconstruction changes the part steel reinforced aluminium conductor into the carbon fiber complex core aluminium stranded conductor at present, carbon fibre composite is high temperature resistant, be subjected to influence of temperature change little, anti-ecological deterioration by force, not with the reaction that produces electrolysis of aluminum conductor or other parts, but since it with lead, study for a second time courses one has flunked bar temperature coefficient different, can make in the long-term creep process of expanding with heat and contract with cold that lead attenuates, degree of speeding increases, and holding of lead puted forth effort very big influence.Therefore the existing bar of studying for a second time courses one has flunked can not satisfy studying for a second time courses one has flunked of carbon fiber composite core wire at all.

Summary of the invention:

The utility model is for a kind of carbon fiber composite core wire repair sleeve is provided.Mainly be that the temperature coefficient that solves carbon fiber complex core and lead, study for a second time courses one has flunked bar is different, can make in the long-term creep process of expanding with heat and contract with cold that lead attenuates, degree of speeding increases, holding of lead puted forth effort influence greatly.Can not satisfy the problem that carbon fiber composite core wire is studied for a second time courses one has flunked.

Scheme of the present utility model is as described below: this utility model comprises aluminum pipe, and it is by the two ends at aluminum pipe chamfering and circular arc to be set, and it axially is provided with a breach, establishes in the breach that the drawer that matches with breach constitutes.

The beneficial effects of the utility model: because this utility model has taked to be provided with the structure that the drawer that matches with breach is arranged in the aluminum pipe of breach and the breach, during installation, carbon fiber composite core wire should be placed in the aluminum pipe by drawer, carry out crimping then.Like this, not only lead is carried out good studying for a second time courses one has flunked, also can obviously increase holding of lead and put forth effort, effectively increase the electrical contact performance of lead, have simple in structure, easy to use, advantages such as contact is firm, dependable performance, economical and practical, suitable popularization simultaneously.

Description of drawings:

Fig. 1 is the front view of carbon fiber composite core wire repair sleeve;

Fig. 2 is the end view of carbon fiber composite core wire repair sleeve.

Embodiment:

By Fig. 1, carbon fiber composite core wire repair sleeve shown in Figure 2 is at the two ends of aluminum pipe 1 chamfering and circular arc to be set, and at it breach is set axially, merges with the breach kissing that the drawer 2 of pull constitutes but be provided with in the breach.During installation, earlier the drawer on the aluminum pipe 12 is taken out, the carbon fiber composite core wire that needs are studied for a second time courses one has flunked places in the aluminum pipe 1 from indentation, there, it promptly is the outside that aluminum pipe 1 is enclosed within the carbon fiber composite core wire that to study for a second time courses one has flunked, pull on drawer 2 again, carry out crimping in aluminum pipe 1 outside then, lead and aluminum pipe 1, drawer 2 are become one.

Claims

1. a carbon fiber composite core wire repair sleeve comprises aluminum pipe (1), it is characterized in that: aluminum pipe (1) two ends are provided with chamfering and circular arc, and it axially is provided with a breach, are provided with the drawer (2) that matches with breach in the breach and constitute.
