Abstract
The invention discloses a cable end separate supporting disk. The supporting disk comprises an insulating disk body (1), wherein three radial first grooves (2) are equally distributed in the disk body (1). The supporting disk has the advantages of simple structure, light weight and convenience, safety and reliability in operation.
Description
Technical field
The present invention relates to that a kind of midium voltage cable office puts, pressure resistant testing device, particularly relate to a kind of supporting disk for separately cable socket.
Background technology
Middle pressure crosslinked cable office puts, the withstand pressure detection device overwhelming majority adopts single transformer to boost, whether qualifiedly contribute to investigating each cable like this, so will the carrying out of when carrying out cable partial discharge, voltage-withstand test, the distance of cable socket be all the problem of testing crew of often puzzling at the trial usually.
Triple cable is carrying out in cable partial discharge, voltage-withstand test process, because voltage during voltage test is higher, all at tens kilovolts, when being the voltage cable test of 8.7/15KV as electric pressure, voltage request reaches 30.5KV, electric pressure is that the testing requirements of 26/35KV voltage cable reaches 65KV, so triple cable is when carrying out a core voltage test, just require that all the other two cores reach a safe distance.Cable partial discharge test requires just higher, and this tests mainly detection streamer not damaged, the electric discharge that inside configuration has inclusion-free etc. to cause, if cable socket distance will cause electric discharge not.Existing way be exactly when doing a core test by the centre of wooden unit pad at all the other two core cables, play the effect of separately termination, but this kind of mode is when changing test core, all wooden unit will be taken off and again pad, waste time.
Single core cable is carrying out in cable partial discharge, voltage-withstand test process, and because single core cable is lightweight, during test, high-pressure side more easily causes electric discharge near dish tool and cable.
Therefore those skilled in the art be devoted to develop that a kind of midium voltage cable office puts, voltage-withstand test time can separate the special purpose device of cable socket.
Summary of the invention
Because the above-mentioned defect of prior art, technical matters to be solved by this invention is to provide that a kind of midium voltage cable office puts, voltage-withstand test time can separate the special purpose device of cable socket.
For achieving the above object, the invention provides a kind of cable socket subitem supporting disk, comprise insulation disk body; Described disk body is evenly equipped with three radial the first grooves.
For being better separated cable socket, the thickness of described disk body is 10mm, and diameter is 220mm.
For being better separated cable socket, the width of described first groove is 40mm, and length is 60mm.
For being better separated cable socket, the bottom of described first groove is arc.
For being better separated cable socket, the radius of described arc is 25mm.
For supporting single core cable, described disk body is provided with the second groove.
Preferably, described second groove is deep-slotted chip breaker.
Preferably, the radius of described deep-slotted chip breaker is 40mm.
Preferably, the center line of described second groove is 45 ° with the angle of next-door neighbour's the first groove center line.
The invention has the beneficial effects as follows: structure of the present invention is simple, quality is light and handy, easy to operate, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As depicted in figs. 1 and 2, a kind of cable socket subitem supporting disk, comprise insulation disk body 1, the thickness D of disk body 1 is 10mm, and diameter Ф is 220mm.Disk body 1 is evenly equipped with three radial the first grooves 2, the angle namely between each first groove 2 is 120 °
In the present embodiment, disk body material adopts nylon, to reach light, not damage cable.In other embodiments, other insulating material also can be adopted to make disk body, to reach substantially identical technique effect.
The width L1 of the first groove 2 is 40mm, length L2 is 60mm.The bottom of the first groove 2 is arc, and the radius R 1 of arc is 25mm.
The radius R 2 disk body 1 being provided with the second groove 3, second groove 3 of arc is 40mm.The center line of the second groove 3 is 45 ° with the angle theta of next-door neighbour's the first groove center line.
When before cable partial discharge, voltage-withstand test, supporting disk of being itemized by cable socket is stuck on triple cable, to reach the safe distance of needs.If single core cable, then core is stuck in the first groove 2, then is stuck on cable finished product external diameter with the second groove 3, take off after having tested.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
