Abstract

The utility model relates to a thirty-five KV-level pure porcelain bushing, and belongs to the technical field of production of transformers and reactor bushings. The utility model adopts the technical scheme that the pure porcelain bushing comprises a porcelain bushing (8), a conductive rod (10), an insulating pipe (9), a flange (14), a sealing ring (13) and metal rods (12), wherein the insulating pipe is sleeved on the outside of the conductive rod located at the center of the bushing, a porcelain sleeve is arranged on the outside of the insulating pipe, the flange is arranged on a magnetic sleeve, a metal coating (11) is sprayed in a length range from an umbrella skirt starting position which is located at the outer surface of the bushing porcelain sleeve and is most close to the flange to the lower portion of the flange, and the sealing ring and the flange are sleeved on the porcelain sleeve, and the plurality of metal rods are inserted in the porcelain sleeve and the flange along the circumference direction. The thirty-five KV-level pure porcelain bushing has the beneficial effects that the insulating pipe sleeved on the outside of the conductive rod at the center of the bushing increases the insulation, the part of the porcelain sleeve with the metal coating is grounded reliably through the flange, which changes the electrode shape of a ground potential, and reduces the electric field strength of the position, thereby reducing partial discharge. The flange, the porcelain sleeve, the sealing ring and the metal rods are firmly pasted through epoxy-resin adhesive to reliably seal.

Description

A kind of 35 kilovolts of level true procelain sleeve pipes
Affiliated technical field:
The utility model relates to a kind of 35 kilovolts of level true procelain sleeve pipes, belongs to transformer and reactor sleeve pipe manufacturing technology field.
Background technology:
Sleeve pipe is that the winding with transformer or reactor is connected in the electric wiring and surrounding devices is played the significant components of insulating effect.Partial discharge quantity and sealing are two in the important indicator that requires of sleeve technology, the partial discharge quantity of sleeve pipe directly affects the partial discharge quantity of transformer integral body, partial discharge quantity is crossed the aging and destruction that conference causes insulation, reduces its useful life, thereby influences the safe operation of equipment.The sealing of sleeve pipe will prevent that not only transformer oil from leaking out, and will prevent that more moisture from entering transformer or reactor inside, damages equipment.
The utility model content:
The utility model purpose provides a kind of 35 kilovolts of level true procelain sleeve pipes, and low, the good airproof performance of partial discharge quantity solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
35 kilovolts of level true procelain sleeve pipes comprise insulator, conducting rod, insulated tube, ring flange, seal ring, metal bar, the conducting rod outside that is positioned at the cover tube hub is with insulated tube, the insulated tube outside is an insulator, ring flange is arranged on the magnetosheath, sleeve pipe insulator outer surface the full skirt of close mounting flange begin the place, spray metal coating to the length range of ring flange bottom, seal ring and ring flange are enclosed within on the insulator, and along the circumferential direction insert the number of metal rod at insulator and ring flange, between metal coating and the ring flange by the metal bar conducting.
Solidify bonding with epoxy resin binder between ring flange and the insulator.
The conducting rod outside of the utility model cover tube hub is with insulated tube to increase insulating properties.When sleeve pipe is made, sleeve pipe insulator outer surface the full skirt of close mounting flange begin the place, spray metal coating to the length range of flange bottom, seal ring and ring flange are enclosed within on the insulator, and along the circumferential direction insert the number of metal rod at insulator and ring flange, to guarantee that ring flange reliably contacts with metal coating, such purpose is by the ring flange reliable ground with metal coating insulator partly, change earthy electrode shape, reduce the electric field strength of this position, thereby reduce partial discharge quantity.Ring flange, insulator will be cured bonding by epoxy resin binder, accomplish positiver sealing.
In addition, also solidify bondingly between the cover of sleeve pipe head, the insulator, be pressed in seal ring with respect to simple will the cover that the such traditional structure of sealing has improved sealing herein on the insulator with nut by epoxy resin binder.
The beneficial effects of the utility model: the conducting rod outside of cover tube hub is with insulated tube increases insulating properties, the insulator of metal coating part is passed through the ring flange reliable ground, change earthy electrode shape, reduce the electric field strength of this position, thereby reduce partial discharge quantity.Ring flange, insulator, seal ring, metal bar will be cured bonding by epoxy resin binder, accomplish positiver sealing.
Description of drawings:
Accompanying drawing is the utility model example structure schematic diagram;
Among the figure: connector lug 1, nut 2, packing ring 3, gland 4, seal ring 5,7,13, cover 6, insulator 8, insulated tube 9, conducting rod 10, metal coating 11, metal bar 12, ring flange 14.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, 35 kilovolts of level true procelain sleeve pipes comprise insulator 8, conducting rod 10, insulated tube 9, ring flange 14, seal ring 13,1 metal bar 12, the conducting rod outside that is positioned at the cover tube hub is with insulated tube, the insulated tube outside is an insulator, ring flange is arranged on the magnetosheath, sleeve pipe insulator outer surface the full skirt of close mounting flange begin the place, spray metal coating 11 to the length range of ring flange bottom, seal ring and ring flange are enclosed within on the insulator, and along the circumferential direction insert the number of metal rod at insulator and ring flange.Ring flange 14, insulator 8 will be cured bonding by epoxy resin binder, also solidify bonding by epoxy resin binder between the cover 6 of sleeve pipe head, the insulator 8.
