Description

Extremely frigid zones flexible cable joint
Technical field
The present invention relates to a kind of cable connector.
Background technology
Extremely frigid zones underground power cable damages at present, it is impossible to when generation joins power supply, traditional approach can only be taked to solve, i.e. use instrument Device search Method of Cable Trouble Point position, handle account for dig road formality, excavate high alpine frost soil buried cable trouble point, make right Joint and pressure test qualified after can restore electricity.Usual each link uses rotational personnel's mode to work continuously repairing, needs Within about 48 hours, just can restore electricity, but if in the case of the more difficult lookup of Method of Cable Trouble Point, it is necessary to take more repairing Time, in a few days the most sometimes, all cannot find position of failure point.This has had a strong impact on failure cable line powering zone user Normal electricity consumption, cause the electricity sales amount of power supply enterprise's large losses.
Authorized announcement date be December in 2010 22 days, Publication No. CN201681656U " a kind of use composition metal screen The direct current high voltage cable of shield structure " in disclose a kind of direct current high voltage cable, this cable is applicable to different needs and obtains direct current High-tension use occasion, but after damaging for extremely frigid zones power cable, this cable cannot realize temporary power.
Summary of the invention
It is an object of the invention to provide a kind of extremely frigid zones flexible cable joint, to solve current extremely frigid zones underground electric electricity Cable damages staff and rushes to repair difficulty, the normal electricity consumption affecting failure cable line powering zone user and cannot quickly realize facing Time the problem powered.
The present invention solves that above-mentioned technical problem adopts the technical scheme that: the described power cable connector of present embodiment includes Copper core, the first semi-conductive layer, insulating barrier, EP rubbers layer, the second semi-conductive layer, screen layer, thermoplastic protection insulating barrier and Terminal, copper core is made up of many copper wires, a diameter of 0.12mm of every copper wire, and the first semi-conductive layer is wrapped in outside copper core Portion, insulating barrier is wrapped in the outside of the first semi-conductive layer, and EP rubbers layer is wrapped in the outside of insulating barrier, the second semi-conductive layer Being wrapped in the outside of EP rubbers layer, screen layer is wrapped in the outside of the second semi-conductive layer, and thermoplastic protection insulating barrier is wrapped in screen Covering the outside of layer, copper core is connected with terminal.
The method have the advantages that winter cold, power cable damage is serious, and double cables are out of service, and cannot generation The particularly urgent situation joined, uses this cable connector to carry out provisional repairing power supply, can reach the purpose of fast recovery of power supply.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the present invention, and Fig. 2 is the structural representation of detailed description of the invention one, and Fig. 2 is concrete The structural representation of embodiment two.
Detailed description of the invention
Detailed description of the invention one: combine Fig. 1 and present embodiment is described, the described power cable connector of present embodiment includes copper Core the 1, first semi-conductive layer 2, insulating barrier 3, EP rubbers layer the 4, second semi-conductive layer 5, screen layer 6, thermoplastic are protected Insulating barrier 7 and terminal 8, copper core 1 is made up of many copper wire 1-1, a diameter of 0.12mm of every copper wire 1-1, and the first half Conductive layer 2 is wrapped in the outside of copper core 1, and insulating barrier 3 is wrapped in the outside of the first semi-conductive layer 2, EP rubbers layer 4 Being wrapped in the outside of insulating barrier 3, the second semi-conductive layer 5 is wrapped in the outside of EP rubbers layer 4, and screen layer 6 is wrapped in The outside of two semi-conductive layers 5, thermoplastic protection insulating barrier 7 is wrapped in the outside of screen layer 6, and copper core 1 is connected with terminal 8.
Detailed description of the invention two: combining Fig. 2 and present embodiment is described, the power cable connector of present embodiment also includes rainproof Skirt 9, described Rain-proof skirt 9 is hollow round table shape, and Rain-proof skirt 9 is sleeved on the thermoplastic protection outside of insulating barrier 7 and the two is made Integrally.Other embodiment is identical with detailed description of the invention one.
Detailed description of the invention three: combining Fig. 3 and present embodiment is described, the power cable connector of present embodiment also includes elbow-type 10, elbow-type 10 is contained in the end of thermoplastic protection insulating barrier 7 and the two closely cooperates.Other embodiment is real with concrete Execute mode one identical.
Operation principle: when double cables damage, it is impossible to band is joined, if rushed to repair by normal method, due to weather in severe winter, it is contemplated that the used time Time is long, and extreme influence power supply quality is used multi-function head flexible cable temporary power scheme by this.Use two on the ground Section (100 meters every section) multi-function head flexible cable is connected, it is achieved temporary power.
Rush Repair Scheme implements the technical staff of cable center according to site contour, layout Rush Repair Scheme and safety measure, use bucket Flexible cable is carried out wall suspension by arm crane, and ground is laid and (marked every 5 meters of settings " halt, Keep Clear-High Voltage " on cable Show), the employing channel-section steel that cannot suspend in midair for footpath part covers, and prevents pedestrian from trampling and rolls with automobile, and jeopardously Section designer's monitoring, all the work used time is shorter.
After energising, cables double to fault carry out trouble shoot again, cable duct excavates, make the work such as transition joint, recover normal and supply After electricity, flexible temporary cable is removed.Use after the present invention carries out temporary power, restore electricity in the short time, at this moment between section Under keep in repair, save substantial amounts of maintenance time.
