Abstract
The invention discloses a universal test fixture for 10kV cables, which comprises a rectangular insulating plate, wherein a row of cable clamping grooves is formed in the longitudinal direction on one side of the insulating plate; the cable clamping grooves are rectangular; a clamping block is slidably arranged in each cable clamping groove; slide rail mechanisms are arranged between two side walls of the clamping blocks and the cable clamping grooves; and the clamping blocks are controlled by a clamping adjustment mechanism and slide along the slide rail mechanisms to clamp cables placed in the cable clamping grooves. According to the universal test fixture of 10kV cable, the cable heads do not have to be readjusted in the test gap during the cable direct current test, the cable insulation test and the cable voltage withstand test, and the tests do not have to be watched by someone to prevent the own deformation of the cable heads.
Description
Technical field
The present invention relates to the universal test fixture of cable.
Background technology
10kV high-voltgae pothead generally need carry out cable DC experiment, cable insulation test and cable voltage test after making.After cable termination completes, need by three-phase electricity cable end separately before cable testing, at present, cable end usually can occur in process of the test and cannot meet testing requirements because own type change makes the distance between three-phase ferrule shorten; Also having a kind of situation to be cable end because own type becomes makes three-phase ferrule in circumferential metal thing, as ring main unit, case become, distance between switch cubicle frame shortens and illegally meets testing requirements, therefore, often need again to adjust cable end.
Summary of the invention
Technical matters to be solved by this invention is just to provide the universal test fixture of a kind of 10kV cable, avoids cable end can not meet testing requirements because own type change makes the distance between three-phase ferrule shorten.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the universal test fixture of 10kV cable, comprise the insulcrete of one piece of rectangle, described insulcrete width side is provided with row's cable clamping slot along its length, described cable clamping slot is rectangular, slide in described cable clamping slot and be provided with a clamp, be provided with sliding track mechanism between described clamp and cable clamping slot two side, described clamp controls to slide along sliding track mechanism the cable that insert in cable clamping slot to be clamped by clamping governor motion.
Preferably, described sliding track mechanism comprises the sliding-rail groove that clamp two side is arranged, and described sliding-rail groove is held on cable clamping slot two side.
Preferably, described clamping governor motion comprises adjusting screw(rod), and described cable clamping notch is provided with fixed block, and described adjusting screw(rod) is threaded with the threaded hole at fixed block center.
Preferably, described cable clamping bottom land end is provided with V-type bottom surface.
Preferably, described clamp is provided with V-type intermediate plate.
Preferably, described V-type intermediate plate is made up of two panels intermediate plate, described clamp is provided with clip groove, described intermediate plate is articulated with in described clip groove, be provided with forward block between described clamp and described adjusting screw(rod), described forward block comprises push pedal, is provided with sliding track mechanism between described push pedal and cable clamping slot two side, be provided with one in the middle part of described push pedal and promote mainly head promotion clamp, described push pedal both sides are provided with thruster head and promote intermediate plate rotation.
Preferably, described insulcrete is made up of epoxy resin.
Preferably, described adjusting screw(rod) is made up of ABS.
The universal test fixture of 10kV cable of the present invention is made up of all insulation material, and without any metal parts, good insulation preformance, can to 400mm
2below containing 400mm
2threephase cable is all tested, and without the need to again adjusting cable end when testing gap when adopting this fixture to test cable DC experiment, cable insulation test and cable voltage, and prevents cable end own type from becoming without the need to sending special messenger to nurse during test.
