Abstract
The invention discloses a kind of cable socket subitem support plate, including insulation disk body (1)；Uniformly distributed the first groove (2) there are three radial direction on the disk body (1).The configuration of the present invention is simple, quality is light and handy, easy to operate, safe and reliable.
Description
Technical field
The present invention relates to a kind of midium voltage cable partial discharge, pressure resistant testing device, more particularly to one kind for separately cut cable
The support plate of head.
Background technology
Middle pressure crosslinked cable partial discharge, the resistance test equipment overwhelming majority are boosted using single-phase transformer, are contributed in this way
Investigate whether each single item cable is qualified, so progress that will be one one when carrying out cable partial discharge, voltage-withstand test, usually exists
The problem of distance of cable socket is all normal puzzled testing crew during experiment.
Three-core cable is carrying out cable partial discharge, during voltage-withstand test, and voltage is higher during due to voltage test, all tens
Kilovolt, voltage request reaches 30.5KV, voltage class 26/35KV when being tested such as voltage class for the voltage cable of 8.7/15KV
Voltage cable test requirements document reaches 65KV, so three-core cable is when carrying out a core voltage test, it is desirable to which remaining two core reaches
One safe distance.Cable partial discharge test requirement is with regard to higher, this experiment is mainly that detection cable has not damaged, and inside configuration has
Electric discharge caused by free from admixture etc., if cable socket distance will not enough cause electric discharge.Existing method is exactly to do core experiment
When by wooden unit pad in the centre of remaining two core cable, play the role of separated end, but such mode replace test core when,
Wooden unit will be removed and padded again, wasted time.
Single-core cable is carrying out cable partial discharge, during voltage-withstand test, since single-core cable is light-weight, high-pressure side during experiment
Easily cause electric discharge close to disk tool and cable.
Therefore those skilled in the art are dedicated to that when developing a kind of midium voltage cable partial discharge, voltage-withstand test cable socket can be separated
Dedicated unit.
Invention content
In view of the drawbacks described above of the prior art, the technical problems to be solved by the invention are to provide a kind of midium voltage cable office
Put, voltage-withstand test when can separate the dedicated unit of cable socket.
To achieve the above object, the present invention provides a kind of cable socket subitem support plate, including the disk body that insulate；The disk
Uniformly distributed the first groove there are three radial direction on body.
Preferably to detach cable socket, the thickness of the disk body is 10mm, a diameter of 220mm.
Preferably to detach cable socket, the width of first groove is 40mm, length 60mm.
Preferably to detach cable socket, the bottom of first groove is arc.
Preferably to detach cable socket, the radius of the arc is 25mm.
To support single-core cable, the second groove is provided on the disk body.
Preferably, second groove is arc groove.
Preferably, the radius of the arc groove is 40mm.
Preferably, the center line of second groove is 45 ° with the angle close to the first groove center line.
The beneficial effects of the invention are as follows：The configuration of the present invention is simple, quality is light and handy, easy to operate, safe and reliable.
Description of the drawings
Fig. 1 is the structure diagram of the embodiment of the invention.
Fig. 2 is the A-A schematic cross-sectional views of Fig. 1.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As depicted in figs. 1 and 2, a kind of cable socket subitem support plate, including the disk body 1 that insulate, the thickness D of disk body 1 is
10mm, diameter Ф are 220mm.Uniformly distributed the first groove 2 there are three radial direction on disk body 1, i.e., the angle between each first groove 2 are
120°
In the present embodiment, disk body material uses nylon, to reach light, not damage cable.In other specific embodiments
In, other insulating materials can also be used and make disk body, to reach essentially identical technique effect.
The width L1 of first groove 2 is 40mm, and length L2 is 60mm.The bottom of first groove 2 be arc, the radius of arc
R1 is 25mm.
The second groove 3 of arc is provided on disk body 1, the radius R2 of the second groove 3 is 40mm.The center of second groove 3
Line is 45 ° with the angle theta close to the first groove center line.
Before cable partial discharge, voltage-withstand test, cable socket subitem support plate is stuck on three-core cable, to reach needs
Safe distance.If single-core cable, then core is stuck in the first groove 2, then cable finished product outer diameter is stuck in the second groove 3
On, it is removed after having tested.
The preferred embodiment of the present invention described in detail above.It should be appreciated that those of ordinary skill in the art without
Creative work is needed according to the present invention can to conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
