Abstract
This utility model is related to a kind of transformator Buchholz relay exhaust apparatus, and which is made up of front end connector, exhaustor, air bleeding valve and seal support part, and front end connector is arranged on the front end of exhaustor, and with the interface that can be connected with Buchholz relay exhaust nozzle；Air bleeding valve is arranged on the end of exhaustor；Seal support part is enclosed within exhaustor and through Buchholz relay side wall.This utility model is arranged on existing transformator Buchholz relay, aerofluxuss operation continually need not be operated on Buchholz relay again, need not ascend a height again operation so as to overhaul operation maintenance personnel, while Buchholz relay exhaust nozzle potted component can also be avoided to loosen permeability causes Buchholz relay misoperation.
Description
Technical field
This utility model is related to a kind of transformator and safeguards auxiliary equipment, particularly a kind of transformator Buchholz relay aerofluxuss dress
Put.
Background technology
At present, for the needs to power grid maintenance, the frequency for carrying out on-load voltage regulation operation to main transformer in electrical network is very
It is intensive.Frequently the electric arc produced by on-load voltage regulating switch action causes transformer oil to gasify, and causes in-house generation gas,
Main transformer is caused to have load Buchholz relay inner upper end gather qi together, for this purpose, and logical aerofluxuss operation must be carried out to Buchholz relay.At present
Logical exhaust mode mainly have two kinds：One is power failure operation, and two is hot line job.Power failure operation moves back the transformator for loading
Go out operation, the reliability powered during reducing operation；Hot line job then dangerous hidden danger, easily causes personnel's electrification electric shock thing
Therefore, frequently deflating to easily cause sealing device element and loosen permeability makes Buchholz relay misoperation etc..Additionally, this powered deflation
Operation can not be operated by operation maintenance personnel by regulations, when operation maintenance personnel finds to carry out the situation of deflation operation, it is necessary to Xiang Jian
The department of repairing reports for repairment, is come personally operation by special maintainer.
The content of the invention
In order to solve above-mentioned the deficiencies in the prior art, this utility model provides a kind of transformator gas relay easy to operate
Device exhaust apparatus.
What the purpose of this utility model was realized in：A kind of transformator Buchholz relay exhaust apparatus, it is characterised in that
It is made up of front end connector, exhaustor, air bleeding valve and seal support part, front end connector is arranged on the front end of exhaustor, and has
There is the interface that can be connected with Buchholz relay exhaust nozzle；Air bleeding valve is arranged on the end of exhaustor；Seal support part is enclosed within aerofluxuss
On pipe and through Buchholz relay side wall.
Described exhaustor is two-part structure, and two sections of exhaustors are connected by seal connector.
Described front end connector, air bleeding valve and exhaustor are and are tightly connected.
Sealing state is between described seal support part and Buchholz relay side wall and exhaustor to contact.
This utility model is arranged on existing transformator Buchholz relay, and aerofluxuss operation need not again continually in gas relay
Operate on device, need not ascend a height again operation so as to overhaul operation maintenance personnel, while Buchholz relay exhaust nozzle sealing unit can also be avoided
Part loosens permeability and causes Buchholz relay misoperation.Exhaustor of the present utility model is caused into lower height, because of its difference in height and
The principle of pressure, operation maintenance personnel can be exhausted operation at any time without being come personally by special maintainer again, improve work
The promptness of efficiency and O＆M.
Description of the drawings
Fig. 1 is the structural representation on transformator Buchholz relay of the present utility model；
Fig. 2 is the partial sectional view that this utility model is arranged on transformator Buchholz relay.
Specific embodiment
It is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, 2, this utility model is made up of front end connector 1, exhaustor 2, air bleeding valve 3 and seal support part 4.
Front end connector is arranged on the front end of exhaustor, and the front end connector of the present embodiment is coupling nut, its female thread and gas after
The external screw thread of 6 exhaust nozzle 14 of electrical equipment is engaged.Sealing ring 5 is provided between Buchholz relay exhaust nozzle and coupling nut, front end connects
It is also to be tightly connected between fitting and exhaustor.
Air bleeding valve is arranged on the end of exhaustor, and which is to be tightly connected with exhaustor.
Seal support part is enclosed within exhaustor, and the seal support part of the present embodiment is the bolt being enclosed within exhaustor, bolt
External screw thread be engaged with the female thread of through hole 9 on Buchholz relay side wall 7.Also in sealing between Buchholz relay and exhaustor
State.The setting of seal support part is prevented from the rainwater and dust in the external world etc. and enters inside Buchholz relay.
Exhaustor can be divided into two-part structure, and its total length can be determined according to job demand.Two sections of exhaustors are by close
Envelope connector 8 is connected.The seal connector of the present embodiment is made up of silk braid 10, swivel nut 11, end-to-end jointing nozzle 12 and sealing ring 13.
Using method of the present utility model is：By the exhaust nozzle pair on the coupling nut of exhaustor leading portion and Buchholz relay
After connecing, through hole of the exhaustor from the wall of Buchholz relay side is caused into outside, and sealing carrying bolt is tightened on into lateral through aperture
On.Again the back segment of exhaustor is closely connected with leading portion by seal connector, the air bleeding valve of aerofluxuss pipe end is caused and is easy to
The correct position and height of operation.Opening air bleeding valve can carry out the aerofluxuss operation of Buchholz relay.
