Abstract
A kind of distribution box of transformer substation cable screening wire prosthetic device, including repairing mould, can the copper sleeve of folding.Repairing mould includes heated chuck (1) and fixture stand (3), heated chuck is cuboid and similar semi-open type connection tile structure, a semi-circular recesses (5) is had in the middle part of the medial surface of chuck, and it is disposed with thermocouple at semicircular groove vicinity, connecing external power source by electric wire even (2) makes thermocouple work, for aluminothermy alloy material；Can the copper sleeve of folding, be two half cylindrical structure, be connected by hinge, just can put heated chuck central slot into, the shielding line being wound around with macromolecular material pyrocondensation belt is coated and fixed so that it is tighten to contract during heating.Copper sleeve lining scribbles polytetrafluorethylecoatings coatings, it is to avoid band is by the unfavorable demoulding of blocking under warming.This utility model device is light and handy, easy to carry, simple to operate rapidly, be particularly suitable for the reparation of distribution box of transformer substation cable screening wire.
Description
Technical field
This utility model relates to a kind of distribution box of transformer substation cable screening wire prosthetic device, belongs to electrical material maintenance tool technical field.
Background technology
At present, the signal in distribution box of transformer substation and control cable use shielded cable in a large number.The screen layer of shielded cable need to be excluded the interference signal by ground connection, arrives after power distribution cabinet, is typically chosen and cuts cladding rubber and extracted out by mesh shields line, and the shielding line extracted out from every cable is mutually wound around to be weaved into plait shape and be connected with grounding copper bar.Reduce cost to save resource, now commonly use copper-clad aluminum conductor and replace circular copper wire as screen layer.And because in the environment of having moisture, copper-clad aluminum conductor is easily formed copper Aluminium primary cell corrosion mechanism, it there will be corrosion until the phenomenon of fracture in the big plait section of braiding so that function of shielding weakens or loses, and causes severe compromise.In the work all changed the shielding line lost efficacy, society and economic aspect all being caused no small loss, the new shielding line changed still has partial denudation in atmosphere, it is impossible to ensure will not again corrode in the use afterwards of the new shielding line changed.Therefore, detection during to lose functional shielding line and occur corrosion but the reparation of the shielding line little to function effect is a requisite step.
Summary of the invention
The purpose of this utility model is, the limitation existed according to existing direct replacing shielding line mode, it is provided that a kind of distribution box of transformer substation cable screening wire prosthetic device.
The technical solution of the utility model is, a kind of distribution box of transformer substation cable screening wire prosthetic device includes repairing mould and can the copper sleeve of folding.
Described repairing mould includes fixture stand, heated chuck and thermocouple；Fixture stand is a similar pincer structure, and one end is two handles, and the both sides of the other end have been respectively mounted a heated chuck；Described heated chuck is cuboid and similar semi-open type connection tile structure, a semi-circular recesses is had in the middle part of the medial surface of chuck, the radius of this groove is formulated to an array of sizes to adapt to different scenes according to the radius specification of on-the-spot shielding line, and it is disposed with thermocouple at semicircular groove vicinity, connects external power source by electric wire and thermocouple is worked；Chuck is formed by special die cast by aluminothermy alloy material, and is drilled with hole, location on chuck；Described special fixture stand uses the structure that cast iron is special, is bolted and forms, and has the attachment structure matched with hole, above-mentioned chuck location.
The beneficial effects of the utility model are, this utility model is not only against the loss changing the economy and society that satisfactory new shielded-conductor cable is caused, and ensure that the long-time interior normal work afterwards of the new shielded-conductor cable changed is not corroded, eradicate the most exposed hidden danger being likely to result in accident in atmosphere of shielding line, this utility model device is light and handy simultaneously, easy to carry, simple to operate rapidly, be particularly suitable for the reparation of distribution box of transformer substation cable screening wire.

Detailed description of the invention
Detailed description of the invention of the present utility model is as shown in the figure.
The present embodiment a kind of distribution box of transformer substation cable screening wire prosthetic device include repairing mould, can the copper sleeve 9 of folding and temperature controller.Repairing mould includes heated chuck 1 and special fixture stand 3, described heated chuck 1 is cuboid and similar semi-open type connection tile structure, there is a semi-circular recesses 5 the i.e. middle part at the medial surface of chuck, the radius of this groove 5 is formulated to an array of sizes to adapt to different scenes according to the radius specification of on-the-spot shielding line, and around semicircular groove 5, it is disposed with thermocouple 6, connecting external power source by electric wire 2 makes thermocouple work, chuck is formed by special die cast by aluminothermy alloy material, and is drilled with hole 7, location on chuck；Described special fixture stand 3 uses the structure that cast iron is special, is formed by connecting by bolt 4, and has the attachment structure matched with hole 7, above-mentioned chuck location.
When closing exposed shielding line part outside, we first use a kind of macromolecular material pyrocondensation belt having heat shrink and PUR filling function to be wound, with can the copper sleeve 9 of folding be coated and fixed before heating it.
Finally can put back in heated chuck 1 by the copper sleeve of folding 9, make the pyrocondensation belt backward contract that is heated tighten.
