The grounded shield screen is connected with four mounting grounded inserts of the sleeve, the equalizing ring is connected with a high voltage silicone rubber lead of a product, the partition board for fixing a conductor is arranged in the middle of inside of the insulating sleeve, and the insulating sleeve is elliptic. In use, the equalizing shield screen is connected with the rectangular conductor through the silicone rubber lead, thereby eliminating air gap between the rectangular conductor and the sleeve, and ensuring operational safety of a power system.
Description
Technical field
The utility model relates to the technical field of power equipment insulating sleeve.
Background technology
The miniaturization of the 35kV high voltage switchgear of using along with China's electric power system power transmission and distribution, greatly developing of metal all-closed structure, the profile physical dimension and the floor space of switchgear will greatly reduce, because after the reduced profile of switchgear, also corresponding the dwindling of distance between the energized conductor in the equipment, electric field between the electrode is more concentrated, more inhomogeneous, particularly electric conductor still is outstanding by the non-uniform electric field between the housing of switchgear, air insulation between electric conductor distance is not enough simultaneously, in order to guarantee the safe operation of equipment, charged electric conductor all adopts the not enough problem of air insulation distance between compound inslation solution conductor, Insulation Problems and non-uniform electric field when solving electric conductor by the switchgear housing, design the oval insulating sleeve of band grading ring, this sleeve pipe is particularly suitable for being installed on the rectangular electric conductor switchgear, be used for the insulation of rectangular electric conductor, when rectangular electric conductor is passed oval insulating sleeve, between the width of conductor and thickness direction and internal surface of sleeve pipe apart from basically identical, the basic uniformity of the electric field that produces between electric conductor and internal surface of sleeve pipe, the high pressure electric conductor of the 35kV high voltage switchgear that whole electric power system power transmission and distribution are used are the rectangle busbar more than 90%.
Existing band grading ring sleeve pipe is annular, when rectangular electric conductor is passed sleeve pipe, distance between the width of its electric conductor and thickness direction and internal surface of sleeve pipe differs greatly, the extremely uneven electric field of formation between electric conductor and internal surface of sleeve pipe, therefore circular sleeve is particularly suitable for wearing circular electric conductor, between circle bus electric conductor and circular sleeve inwall apart from consistent, the basic uniformity of electric field that produces between its circle electric conductor and internal surface of sleeve pipe, the high pressure electric conductor of the 35kV high voltage switchgear that whole electric power system power transmission and distribution are used are that circular bus is as electric conductor less than 10%.
The organization plan of existing band grading ring insulating sleeve: product design is circular, product is by the epoxy resin mixed glue injection-compression molding, the outer surface of product has big or small shirt rim, purpose be increase product along the face creepage distance, internal structure is made up of earth shield net and grading ring, 4 of earth shield net and sleeve pipe the ground connection inserts is installed and is linked, grading ring (semiconductor varnish) links with the high pressure silicon rubber lead-in wire of product, and the interior middle part design of product has the fixedly dividing plate of electric conductor.
The shortcoming of prior art, existing band grading ring insulating sleeve is circular, when rectangular electric conductor is passed sleeve pipe, distance between the width of its electric conductor and thickness direction and internal surface of sleeve pipe differs greatly, the extremely uneven electric field of the electric conductor of rectangle and the formation between internal surface of sleeve pipe, product is in operation because the electric field pole uneven distribution between rectangular electric conductor and insulating sleeve, produce the corona discharge phenomenon, the conduit of equipment is in long-term corona discharge, the ageing of insulation of expedite product, reduce the useful life of product on the one hand, the long-pending effect in the base of long-term discharge can cause that the puncture of product has caused electrical network generation interruption of service on the other hand.
The utility model content
The utility model purpose aims to provide a kind of high voltage electric power equip ment insulating sleeve, and power equipment is in operation, and power system operation safety is guaranteed in the corona free discharge between rectangular electric conductor and insulating sleeve.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high voltage electric power equip ment insulating sleeve, comprise earth shield net, grading ring, dividing plate, wherein 4 of earth shield net and sleeve pipe installation ground connection inserts link, the high pressure silicon rubber lead-in wire of grading ring and product links, it is oval that the interior middle part design of this insulating sleeve has the fixedly dividing plate of electric conductor, this insulating sleeve profile.
Described high voltage electric power equip ment insulating sleeve, this insulating sleeve is by the epoxy resin mixed glue injection-compression molding.
Described high voltage electric power equip ment insulating sleeve, this insulating sleeve outer surface has big or small shirt rim.
The beneficial effect that the oval high voltage electric power equip ment insulating sleeve of the utility model patent brings:
The oval insulating sleeve of band grading ring, be used for the insulation of rectangular electric conductor, when rectangular electric conductor is passed oval insulating sleeve, between the width of conductor and thickness direction and internal surface of sleeve pipe apart from basically identical, the basic uniformity of the electric field that produces between electric conductor and internal surface of sleeve pipe, product is in operation, corona free discharge between rectangular electric conductor and insulating sleeve, design to have in the oval insulating sleeve simultaneously and all press gauze screen, this gauze screen is mainly at sleeve pipe mounting flange place, and the electric field at mounting flange place is concentrated especially, sleeve pipe in use all presses gauze screen to link with rectangular electric conductor by the silicon rubber lead, eliminated the air gap between rectangular electric conductor and sleeve pipe, guarantee power system operation safety, this type ovate canula has solved circular casing in service and has worn the shortcoming that rectangular electric conductor produces corona discharge, ovate canula is widelyd popularize and is used in existing 35kV switchgear, to the circular casing that has been in operation, and be to wear rectangular electric conductor, many transformer stations are all transforming, be replaced with the oval insulating sleeve of band grading ring, guarantee the security of operation of 35kV electric power system.
