Abstract
The utility model discloses a kind of power cable single transition joints, including transition joint ontology, the transition joint ontology includes the connector of intermediate tube and the intermediate tube both ends, the connector is carried out with the both ends of the intermediate tube by sealing marine glue be bonded, connecting tube is equipped with inside the intermediate tube, the intermediate tube outer surface is divided into two sections, and one section is enclosed with three-layer insulated material, and another section is enclosed with three-layer semiconductor material.The power cable single transition joint greatly reduces interfacial contact surplus between connector and cable, effectively prevents air gap generation, and interface electric property is greatly improved.
Description
Technical field
The utility model relates to power cable technical fields, more particularly to a kind of power cable single transition joint.
Background technique
By transport, execution conditions are influenced, the installation length of power cable generally requires live adjustment.This is just needed pair
Cable is sheared, and is reconnected, and just needs a large amount of transition joint, cable connector and cable body when to laying at the scene
Between be easy to appear that resistance is larger, is not easy the case where being in close contact in connection procedure, it is chronically steady not can guarantee power cable
Fixed operation.
Utility model content
In view of this, the purpose of this utility model is in view of the deficiencies of the prior art, to provide in a kind of power cable single
Between connector, solve above-mentioned technical problem.
In order to achieve the above objectives, the utility model uses following technical scheme:
A kind of power cable single transition joint, including transition joint ontology, the transition joint ontology includes intermediate tube
With the connector at the intermediate tube both ends, the connector and the both ends of the intermediate tube by seal marine glue carry out it is be bonded,
Connecting tube is equipped with inside the intermediate tube, the intermediate tube outer surface is divided into two sections, and one section is enclosed with three-layer insulated material, another
Section is enclosed with three-layer semiconductor material.
Further, the both ends of the connecting tube are fixedly connected with conductor, and the number of conductor is 2.
Further, it is enclosed with half conduction band outside the connecting tube, is enclosed with insulating tape outside the conductor.
Further, copper shield is inlaid on the outer surface of the connector.
Further, the material of the transition joint ontology is silicon rubber or EP rubbers.
Further, the intermediate tube is by stress cone come uniform electric field distribution.
The beneficial effects of the utility model are:
The utility model provides a kind of power cable single transition joint, the material of transition joint ontology be silicon rubber or
Elasticity is good for EP rubbers material, so that interfacial contact surplus greatly reduces between connector and cable, effectively prevents air gap generation, boundary
Face electric property is greatly improved, and using stress cone come uniform electric field distribution, interface electric property is greatly improved, subtract
The generation of air gap between few interface.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
The technical solution of the utility model embodiment is clearly and completely described in the attached drawing of type embodiment.Obviously, described
Embodiment is a part of the embodiment of the utility model, instead of all the embodiments.Based on described the utility model
Embodiment, those of ordinary skill in the art's every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1
As shown in Figure 1, a kind of power cable single transition joint, including transition joint ontology, the transition joint ontology
Connector 2 including intermediate tube 1 and the intermediate tube both ends, 2 number of connector are 2,
The connector 2 and the both ends of the intermediate tube 1 by seal marine glue 3 carry out it is be bonded, inside the intermediate tube 1
Equipped with connecting tube 4,1 outer surface of intermediate tube is divided into two sections, and one section is enclosed with three-layer insulated material 5, and another section is enclosed with three
Layer semiconductor material 6, insulating materials 5 and semiconductor material are wrapped in transition joint outer surface, and playing improves field distribution
Measure.
The both ends of the connecting tube 4 are fixedly connected with conductor 7, and 7 number of conductor is 2, are distributed in the two of connecting tube 4
End.
It is enclosed with half conduction band 8 outside the connecting tube 4, is enclosed with insulating tape 9 outside the conductor.Electrical parameter forces electricity
The electric field evacuation of cable insulating layer section is along axial more uniform distribution.
Copper shield 10 is inlaid on the outer surface of the connector 2.Copper shield 10 avoids transition joint ontology from occurring
Shelf depreciation.
The material of the transition joint ontology is silicon rubber or EP rubbers.Elasticity is good for silicon rubber or EP rubbers material, makes
It obtains interfacial contact surplus between connector and cable to greatly reduce, effectively prevents air gap generation.
The intermediate tube 4 is by stress cone 11 come uniform electric field distribution.Using 11 interface electric property of stress cone obtain compared with
It is big to improve, reduce the generation of air gap between interface.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, this field
Other modifications or equivalent replacement that those of ordinary skill makes the technical solution of the utility model, it is practical without departing from this
The spirit and scope of new technique scheme should all cover in the scope of the claims of the utility model.
