Specific embodiment
The utility model discloses a kind of oil-immersed transformer with plug-in type arrester, in the oil-immersed transformer
Arrester installation steps are simple, and occupy little space.
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are in the premise for not making creative work
Under all other embodiment obtained, fall within the protection scope of the utility model.
Please refer to attached drawing 1- Fig. 2.In a specific embodiment of the present invention, oil-immersed transformer includes transformer device
Body, fuel tank 4 further include plug-in type arrester 1.Transformer body is set in fuel tank 4.Plug-in type arrester 1 includes pedestal 11
With plug 12.Pedestal 11 therein is located in fuel tank 4, and pedestal 11 is connected on fuel tank 4.Plug 12 is located at the outside of fuel tank 4, and
Plug 12 can grafting on the pedestal 11.Preferably, it is immersed in pedestal 11 in the insulating oil in fuel tank 4, can so enhance
Dielectric strength between pedestal 11 and fuel tank 4.
During installation, pedestal 11 need to be only mounted on fuel tank 4, and pedestal 11 is made to be immersed in the insulation of fuel tank 4
In oil, later on the pedestal 11 by 12 grafting of plug, finally wiring is between plug-in type arrester 1 and on high-tension side outlet 2
It can.The pedestal 11 of the plug-in type arrester 1 is located in fuel tank 4, and wiring between plug-in type arrester 1 and on high-tension side outlet 2
It also is located in fuel tank 4, therefore the exterior space that plug-in type arrester 1 occupies reduces.Plug-in type arrester 1 in the utility model
Installation steps are simple, and occupy little space, the compact layout of entire oil-immersed transformer.
Plug 12 and pedestal 11 include insulation crust and the conduct piece in insulation crust, when plug 12 is inserted into bottom
After seat 11, the conduct piece inside plug 12 is connected with the conduct piece inside pedestal 11.Conduct piece and and high pressure inside pedestal 11
The outlet of side is electrically connected.Conduct piece inside plug 12 is electrically connected by ground line with the earth.When the high pressure of oil-immersed transformer
When there is improper high pressure in the outlet of side, the resistance of the conduct piece inside plug 12 can become very small, on high-tension side outlet
On high-tension current the conduct piece inside plug 12 can be flowed by the conduct piece inside pedestal 11, finally by ground line flow
Enter the earth.
Specifically, the pedestal 11 of plug-in type arrester 1 is bolted on fuel tank 4.Plug-in type arrester 1 passes through
Copper stranded conductor 3 is connect with the outlet 2 of on high-tension side every phase.Since when there is improper high pressure, high-voltage impact electric current can be from height
The outlet 2 of pressure side is flowed into plug-in type arrester 1 by copper stranded conductor 3, therefore has coated insulation wadding in the outside of copper stranded conductor 3,
To improve the insulation performance of copper stranded conductor 3.Copper stranded conductor 3 and high-voltage side outlet wire 2 and the connection type of plug-in type arrester 1 are such as
Under: the bottom of 1 pedestal 11 of plug-in type arrester has the stud of wiring, and one end of copper stranded conductor 3 connects wired nose, by line nose
Sub-set screws the nut with stud cooperation on stud later, and line nose is locked on stud by nut, to complete copper strand
The connection of line 3 and stud.The other end of copper stranded conductor 3 and on high-tension side outlet 2 are welded.
For 10kv grade threephase oil immersed transformer, need to be equipped with the plug-in type arrester 1 of three 10kv grades.10kv
The outlet 2 of every phase of grade threephase oil immersed transformer is parallel with the plug-in type arrester 1 of a 10kv grade, such as attached drawing 1
It is shown.In order to ensure copper stranded conductor 3 conductive stability and insulating properties, the area of section of copper stranded conductor 3 can be limited to 15-
17mm2.Thickness limit by the insulation wadding coated outside copper stranded conductor 3 is 2-4mm.
In addition, the oil-immersed transformer with plug-in type arrester 1 in the utility model is doing factory industrial frequency withstand voltage examination
When testing, it is not necessary to remove plug-in type arrester 1, it is only necessary to block the plug of plug-in type arrester 1.
