Abstract
The utility model provides a kind of jockey, mainly solved existing tube type bus lower with insulation conduction inner cone connection reliability, during long-time use, may produce because electro-insulating rubber deformation causes gap, thereby cause partial discharge quantity large, the problem such as insulation property are poor.This jockey comprises insulating sleeve, and insulating sleeve is socketed in tube type bus, and to insert the insulating barrier outside of insulation conduction inner cone upper, also comprises fixture stay pipe and fixture mounting pipe; One section of fixture stay pipe is socketed in insulating sleeve outside, and another section is socketed in the outside of tube type bus insulating barrier; Fixture mounting pipe is socketed in fixture stay pipe outside; Between fixture stay pipe outer wall and fixture mounting pipe inwall, form annular chamber, be provided with spring in annular chamber, spring provides the active force towards insulation conduction inner cone for fixture stay pipe.
Description
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 inner cone of insulation conduction is at present mainly that tube type bus one end is electrically connected to by bolt or by being flexible coupling with the metal sleeve of insulation conduction inner cone with the connected mode of tube type bus, then carries out insulated enclosure processing with insulating tape and sealant tape etc.Because which difficulty of processing is large, 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.
In order to solve the above-mentioned problems in the prior art, technical staff provides a kind of connected mode that adopts insulating sleeve, but the continuous increase due to existing power equipment rated current, cause the pulling force that bear junction constantly to increase, the mode of insulating sleeve is the more difficult satisfied actual needs that use.
Summary of the invention
The utility model provides a kind of jockey, mainly solved existing tube type bus lower with insulation conduction inner cone connection reliability, during long-time use, may produce because electro-insulating rubber deformation causes gap, thereby cause partial discharge quantity large, the problem such as insulation property are poor.
Concrete technical solution of the present utility model is as follows:
This jockey comprises insulating sleeve, and insulating sleeve is socketed in tube type bus, and to insert the insulating barrier outside of insulation conduction inner cone upper, also comprises fixture stay pipe and fixture mounting pipe; One section of described fixture stay pipe is socketed in insulating sleeve outside, and another section is socketed in the outside of tube type bus insulating barrier; Described fixture mounting pipe is socketed in fixture stay pipe outside; Between described fixture stay pipe outer wall and fixture mounting pipe inwall, form annular chamber, be provided with spring in annular chamber, spring provides the active force towards insulation conduction inner cone by fixture stay pipe for insulating sleeve.
On above-mentioned fixture stay pipe outer wall and fixture mounting pipe inwall, be provided with projection, both ends of the spring contacts with two projections respectively.
Above-mentioned fixture mounting pipe is provided with the ring flange for being fixedly connected with insulation conduction inner cone near insulation conduction inner cone one end.
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.
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, 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-insulation conduction inner cone; 2-insulating sleeve; 3-fixture stay pipe; 4-fixture mounting pipe; 5-tube type bus insulating barrier; 6-spring; 7-ring flange;
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, and this jockey comprises insulating sleeve, and insulating sleeve is socketed on the insulating barrier outside that tube type bus inserts insulation conduction inner cone; On the inwall of insulating sleeve and end lap place of tube type bus outer shielding layer, be provided with shading ring; Insulating sleeve and tube type bus insulating barrier are prefabricated as a whole.
Said structure is same as the prior art, and for fear of because electro-insulating rubber deformation causes the generation in gap, this jockey has been set up fixed connection apparatus on the basis of existing structure; The object of fixed connection apparatus is to continue to provide the active force towards insulation conduction inner cone direction to insulating sleeve.The frame mode of fixed connection apparatus is more, can realize above-mentioned purpose, is as the criterion, and this case provides following frame mode:
Fixed connection apparatus is comprised of fixture stay pipe and fixture mounting pipe; One section of fixture stay pipe is socketed in insulating sleeve outside, and another section is socketed in the outside of tube type bus insulating barrier; Fixture mounting pipe is socketed in fixture stay pipe outside, and fixture mounting pipe is fixedly connected with insulation conduction inner cone; Between fixture stay pipe outer wall and fixture mounting pipe inwall, form annular chamber, be provided with spring in annular chamber, spring provides the active force towards insulation conduction inner cone by fixture stay pipe for insulating sleeve.This active force can be realized by be provided with projection on fixture stay pipe outer wall and fixture mounting pipe inwall, both ends of the spring contacts with two projections respectively, when fixture stay pipe court moves away from insulation conduction inner cone direction, be clipped in two springs between projection and can produce active force, prevent the motion of fixture stay pipe.Fixture mounting pipe is provided with the ring flange for being fixedly connected with insulation conduction inner cone near insulation conduction inner cone one end.
