Abstract
The utility model relates to a kind of cable cold-contraction type silicon rubber transition joint tube connector, it reinforces the applicability of joint tube connector, concrete technical scheme is: cable cold-contraction type silicon rubber transition joint tube connector, cable comprises conductor, is equipped with cable insulation outside conductor, and tube connector comprises body, being arranged with shape outside body is hollow cylinder, dismountable shading ring, the internal diameter of shading ring equals the external diameter of tube connector, and external diameter equals the external diameter of cable insulation, and shading ring is also provided with fixing hole.Cable cold-contraction type silicon rubber transition joint tube connector has compatibility, has taken into account the security performance that cable connects while reducing costs.
Description
Technical field
The utility model relates to cable cold-contraction type silicon rubber transition joint tube connector.
Background technology
Various cable generally has specific transition joint tube connector when connecting, but the applicable performance of these tube connectors is not strong.Illustrate: the conductor metal tube connector manufacturing cost of 35kV cold shrink type middle joint standard configuration is higher, the metal material consumed is needed to be higher than common 10kV joint tube connector, the metallic conductor tube connector of buying standard configuration therefore portions of client is unwilling, but adopt the conductor connecting tube of common 10kV to replace, will cause like this 35kV silicon rubber transition joint inner shield pipe cannot with change after metal connecting tube effectively overlap, form space between the two, cause connecting portion and occur high-pressure side partial discharge.In the case, selection semi-conductive tape carries out filling the problem that effectively can solve high-pressure side electric discharge, but perform this technique and can cause new hidden danger, that is: the conductive particle on semi-conductive tape easily by the bracing strip of twitching on cable insulation body, the Partial Discharge Sources that formation one is long-term between cable insulation and joint body like this, run under long-term charged condition, cable insulation level will be caused to decline gradually, finally cause puncturing.
Utility model content
In order to overcome the deficiencies in the prior art, the technical problems to be solved in the utility model improves the applicability of joint tube connector.
For solving the problem, the technical scheme that the utility model adopts is as follows: cable cold-contraction type silicon rubber transition joint tube connector, cable comprises conductor, cable insulation is equipped with outside conductor, described tube connector comprises body, and being arranged with shape outside body is hollow cylinder, dismountable shading ring, and the internal diameter of shading ring equals the external diameter of body, the external diameter of shading ring equals the external diameter of cable insulation, and shading ring is also provided with fixing hole.
Preferably: described body is 10kV joint tube connector.
Preferably: described fixing hole quantity is 4, and is distributed in symmetrically on the sidewall of shading ring.
Preferably: the width of described shading ring is 10mm.
Preferably: the edge of described shading ring is provided with the chamfering of 0.5x0.5.
Preferably: in described fixing hole, be provided with hexagon socket head cap screw.
Compared to existing technology, the beneficial effects of the utility model are: cable cold-contraction type silicon rubber transition joint tube connector has compatibility, such as: body own is that the cable that the tube connector of 10kv goes for 10kv connects, the cable going for 35Kv after cover connects shading ring connects, without the need to using semiconductive material to fill while reducing costs, pass through shading ring, shielded-plate tube in tube connector and joint is effectively overlapped, there will not be Partial Discharge Sources, while promoting its electric property, also improve cold-contraction type silicon rubber transition joint safety in utilization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of the utility model shading ring.
In figure, mark is described as follows:
1, body; 2 shading rings; 3, fixing hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Figure 1-3, cable cold-contraction type silicon rubber transition joint tube connector, cable comprises conductor, cable insulation is equipped with outside conductor, described tube connector comprises body 1, and being arranged with shape outside body 1 is hollow cylinder, dismountable shading ring 2, and the internal diameter of shading ring 2 equals the external diameter of body, the external diameter of shading ring 2 equals the external diameter of cable insulation, and shading ring 2 is also provided with fixing hole 3.
Body 1 is preferably 10kv cable connection tube, use as 35kv cable connection tube after adding shading ring 2, now because shading ring 2 makes the shielded-plate tube in tube connector and joint effectively overlap, there will not be the partial discharge phenomenon occurred when using semiconducting filler, while cost-saving, take into account complete performance.
Fixing hole quantity is 4, and is distributed in symmetrically on the sidewall of shading ring, and shading ring 2 is carried out restriction location preferably by hexagon socket head cap screw by fixing hole 3, prevents it from rotating or sliding displacement.
The width of shading ring 2 is preferably 10mm, and its edge arranges the chamfering of 0.5x0.5, and namely the first chamfering distance is the 0.5, second chamfering distance is 0.5, also can be expressed as 0.5x45 degree.
Above-mentioned execution mode is only preferred implementation of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
