Description
Technical field
The utility model relates to a kind of cable joint part flow arrangement, belongs to electric cable fitting technical field.
Background technology
Along with the extensive use of power cable, a large amount of cable joints must be used in power supply system.Found by the fault data analyzing cable joint, the crooked position of cable joint is the weakest link in safe operation of power system.This is because cable joint normally fabrication and installation at the scene after power cable has been laid, by the impact of site environment unfavorable factor and the restriction of manufacture craft, the fabrication and installation time is more long more easily to be occurred overheatedly to burn accident.Meanwhile, cable joint is after running overload after a while, and usually can produce overheated, oxidative phenomena at crimping point place, contact resistance is increased gradually, and contact temperature raises gradually, accelerates ageing of insulation, finally leads to a disaster.But because existing cable joint can not be shunted, after cable joint is overheated, external force is easy to cause cable joint to come off and has an accident, and has a strong impact on the Problem of live line working personnel.
Summary of the invention
The purpose of this utility model is, provides a kind of structure simple, easy to operate, and after, oxidation overheated at cable joint, working stability safety during live line working, reduces live line working risk; To solve existing cable joint owing to there is overheated, oxidation, the increase of contact point resistance, causes ageing of insulation or after puncturing, the electric current due to cable joint during replacing is excessive, affects the cable joint part flow arrangement of charged operating personnel's Problem problem.
The utility model realizes above-mentioned purpose by the following technical solutions
This cable joint part flow arrangement is made up of Connection Block, slide block, clamping screw and shunting wiring screw rod, it is characterized in that: Connection Block is opened and is shaped with cable connection groove, in the cable connection groove of Connection Block, parcel is provided with slide block, on the right side of slide block, level is manufactured with the half slot matched with cable connection groove, and slide block left vertical is manufactured with two shunting connecting grooves; The side of Connection Block is manufactured with internal thread hole, and internal thread hole is built with clamping screw, and one end of clamping screw is flexibly connected with slide block, and clamping screw can 360 ° of rotations in slide block, and slide block is provided with hold-down screw; Two shunting wiring screw rod are equipped with in the bottom of Connection Block.
The utility model beneficial effect is compared with prior art
This cable joint part flow arrangement adopts Connection Block, slide block, clamping screw to form, and the electric current major part on cable or whole points can be poured off, improve fail safe when changing cable joint live-line maintenance operation, reduce the difficulty of live line working; And structure is simple, easy to operate.Because the electric current of cable joint is excessive when solving existing cable joint spot replace, affect the problem of charged operating personnel's Problem.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
This cable joint part flow arrangement is made up of Connection Block 1, slide block 3, clamping screw 5 and shunting wiring screw rod 6, Connection Block 1 is opened and is shaped with cable connection groove 2, in the cable connection groove 2 of Connection Block 1, parcel is provided with slide block 3, on the right side of slide block 3, level is manufactured with the half slot 9 matched with cable connection groove 2, and slide block 3 left vertical is manufactured with two shunting connecting grooves 7; The side of Connection Block 1 is manufactured with internal thread hole 4, and internal thread hole 4 is built with clamping screw 5, and one end of clamping screw 5 is flexibly connected with slide block 3, and clamping screw 5 in the interior 360 ° of rotations of slide block 3, slide block 3 can be provided with hold-down screw 8; Two shunting wiring screw rod 6 are equipped with in the bottom of Connection Block 1.(see accompanying drawing 1 ~ 3).
The course of work of this cable joint part flow arrangement is as follows:
When cable joint is through running overload after a while, crimp some place produce overheated, oxidative phenomena, ageing of insulation or breakdown after need to change cable joint time, first inlet wire shunt conductor is inserted in the shunting connecting groove 7 on slide block 3, and by clamping screw 5, shunt conductor is tightened, again by outlet shunt conductor and shunting wiring screw rod 6 consolidation, now cable joint is in SHUNT state, and the electric current on cable is by major part or all shunt; Then being unclamped by the hold-down screw 8 on slide block 3, tightened by hold-down screw 8 after being moved to the left by slide block 3 again, cable joint can be taken off and change, then by charging effect or can not there is security incident in the operating personnel of Problem.After cable joint has been changed, the cable joint of inlet wire and outlet is put into cable connection groove 2 and half slot 9, unclamp hold-down screw 8, promote after cable joint compresses by slide block 3 in cable connection groove 2 and half slot 9 by clamping screw 5, by the hold-down screw 8 on slide block 3, slide block 3 is fixed tightly in Connection Block 1, cable joint can be linked into an integrated entity securely, then be unclamped by shunt conductor and take off (also can not take off), then the work of whole replacing cable joint completes.This cable joint part flow arrangement structure is simple, easy to operate, is applicable to very much electric power enterprise operating personnel hotline maintenance and maintenance when changing the cable joint damaged, danger when effectively prevent hotline maintenance and safeguard.
The above is preferred embodiment of the present utility model, above-mentioned illustrating does not do any pro forma restriction to flesh and blood of the present utility model, any simple modification that person of an ordinary skill in the technical field has done above embodiment according to technical spirit of the present utility model after having read this specification or distortion, and the technology contents of above-mentioned announcement may be utilized to be changed or be modified to the Equivalent embodiments of equivalent variations, all still belong in the scope of technical solutions of the utility model, and do not deviate from essence of the present utility model and scope.
