Abstract

The utility model provides a connecting device, which mainly solves the problems in the prior art that an existing tubular busbar and an insulation conductive inner cone are hard to be connected and the connection part thereof is large in magnitude of partial discharge, poor in insulating effect and easy-to-breakdown. The connecting device comprises an insulating sheath. The insulating sheath is sleeved onto the outside of the insulating layer of a tubular busbar to be inserted into an insulation conductive inner cone. When the tubular busbar and the insulation conductive inner cone are connected together by means of the connecting device, the electric field is uniform in distribution. Meanwhile, the connection part of the tubular busbar and the insulation conductive inner cone is small in magnitude of partial discharge, reliable in contact effect, good in insulating effect and hard-to-breakdown.

Description

Jockey

Technical field

The utility model relates to a kind of jockey, is mainly used in being connected of tube type bus and the power equipments such as switch cubicle, transformer, belongs to mesohigh electric power system application.

Background technology

In modern power systems, the use of tube type bus is more and more extensive, the power equipments such as the totally enclosed switch cubicle of the power equipments such as itself and switch cubicle, transformer, particularly inflation, oil-filled or solid insulation, transformer, are all connected with tube type bus by the insulation conduction inner cone on power equipment.

The connected mode of the inner cone of insulation conduction at present and tube type bus mainly contains following two kinds:

1, tube type bus one end is flattened, become writing board shape, be then electrically connected to by bolt with the metal sleeve of insulation conduction inner cone, then carry out insulated enclosure processing with insulating tape and sealant tape etc.Because difficulty of processing is large, writing board shape is irregular, and wedge angle burr is many, and non-uniform electric easily causes junction partial discharge quantity large, and local pyrexia phenomenon frequently occurs, junction insulation is weak, easily punctures.

2, by being flexible coupling, tube type bus and insulation conduction inner cone are coupled together, then carry out insulated enclosure processing with insulating tape and sealant tape etc.This mode difficulty of processing is also large, and Electric Field Distribution is also inhomogeneous, and local pyrexia phenomenon frequently occurs, junction insulation is weak, easily punctures.

Summary of the invention

The utility model provides a kind of jockey, and mainly having solved existing tube type bus and insulation conduction inner cone, to be connected difficulty large, non-uniform electric, junction partial discharge quantity is large, local pyrexia phenomenon frequently occurs and contacts unreliablely, and junction insulation is weak, the problem such as easily punctures.

Concrete technical solution of the present utility model is as follows:

This jockey comprises insulating sleeve, and insulating sleeve is socketed on the insulating barrier outside of tube type bus insertion insulation conduction inner cone.

On the inwall of above-mentioned insulating sleeve and end lap place of tube type bus outer shielding layer, be provided with shading ring.

Above-mentioned insulating sleeve and tube type bus insulating barrier are prefabricated as a whole.

On above-mentioned insulation conduction inner cone conductive sleeve inwall, be provided with watchband-shaped contactor, plum blossom fingertip or the spring touch finger of conduction.

The utility model has the advantage of:

Utilize jockey that the utility model provides to carry out tube type bus while being connected with insulation conduction inner cone, Electric Field Distribution is even, the local discharge off in junction, and contact is reliable, without fever phenomenon, occurs, and insulation well, is difficult for puncturing.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Accompanying drawing is detailed as follows: 1-insulating sleeve; 2-insulation conduction inner cone; 3-tube type bus insulating barrier; 4-insulating sleeve fixation clip; 5-shading ring; 6-fingertip; 7-tube type bus contact tube.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail:

Tube type bus is comprised of contact tube and the insulating barrier that is arranged on contact tube outside, tube type bus is when being connected with insulation conduction inner cone, the jockey of selecting the utility model to provide, the insulating sleeve of this jockey inserts insulation conduction inner cone after being socketed in tube type bus, the contact tube of tube type bus end is electrically connected to the conductive contact finger arranging on insulation conduction inner cone conductive sleeve, conductive contact finger can be watchband-shaped contactor, plum blossom fingertip or spring touch finger, and then by fixation clip, insulating sleeve is compressed and is in place.Insulating sleeve also can be as a whole with the partial precast of tube type bus insertion insulation conduction inner cone.

Because tube type bus is generally shield type, so be provided with shading ring in the outside inner port of insulating sleeve position, the outer shielding layer end of tube type bus is reliably contacted with shading ring, avoid tube type bus outer shielding layer end to have electric discharge phenomena, cause bus insulation to puncture.
