Description
Technical field
A kind of Transformer Manufacturing Technology is the utility model is related to, specifically a kind of power transformer enclosure exhaust structure.
Background technology
According to the design standard of power transformer, to ensure transformer safety operation, need to by during transformer station high-voltage side bus by
The gas that transformer oil and other insulating parts decomposite is discharged in gas relay and oil conservater by union.Due to gas density
It is smaller, eventually rise and be pooled at the peak of oil tank of transformer upper surface and rise seat, it is therefore necessary in above-mentioned position cloth
Acclivitous union is put, in the upper ends gas relay and oil conservater of union, to allow gas to finally enter by union
Enter in gas relay and oil conservater.
As shown in figure 1, for the gas raised in seat is discharged, rise seat union adaptor 2 is placed on the upper end of rise seat.By
Needed in design, the conventional height for raising seat body 1 about in 500~1500mm, raises for some extra-high die pressing products
The height of seat body 1 may reach more than 2000mm.So rise seat union adaptor 2 and oil conservater will be obtained very high by frame,
More than fuel tank cap 3000mm can be higher than, installation difficulty increase, improve installation risk.
Utility model content
For power transformer enclosure in the prior art due to height problem cause installation difficulty increase, increase installation risk
The deficiencies of, problem to be solved in the utility model is to provide a kind of height for reducing union or cancels rise seat union, reduces peace
Fill the power transformer enclosure exhaust structure of difficulty.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of power transformer enclosure exhaust structure of the utility model, it is installed on above fuel tank cap of transformer, raises cover for seat pipe
On current transformer is installed, add gear air ring below current transformer supporting plate, gear air ring is circular ring, its external diameter with
Rise seat internal diameter is identical, and internal diameter is identical with the external diameter of sleeve pipe；Keep off air ring bottom and be provided with exhaust union.
Also there is compression dead ring, be pressed in gear air ring bottom.
Compression dead ring is provided with the notch with exhaust union UNICOM.
Air ring is kept off using oil-resisting and heat-resisting rubber thick 1~1.5mm.
A kind of power transformer enclosure exhaust structure of the utility model, half are located above fuel tank cap of transformer, remainder
Inside oil tank of transformer, gear air ring is added in fuel tank cap lower surface, gear air ring is circular ring, its external diameter and rise seat
Internal diameter is identical, and internal diameter is identical with the external diameter of sleeve pipe.
Also there is compression dead ring, be pressed in gear air ring bottom.
Compression dead ring is provided with the notch with fuel tank UNICOM.
Air ring is kept off using oil-resisting and heat-resisting rubber thick 1~1.5mm.
The utility model has the advantages that and advantage：
1. the utility model is increased by the improvement to power transformer enclosure internal structure at the middle part of rise seat or bottom
Add gear gas insulated ring, artificially reduce the height of gas, to reduce the height of union or cancel rise seat union, realize outside join
The improvement and simplification of pipe, solve the problem of oil conservater, union setting height(from bottom) height, installation difficulty, reach the mesh for reducing installation difficulty
's.

Wherein, 1 is rise seat body, and 2 be rise seat union adaptor, and 3 be sleeve pipe, and 4 be current transformer, and 5 be that electric current is mutual
Sensor supporting plate, 6 be compression dead ring, and 7 be gear air ring, and 8 be fuel tank cap.
Embodiment
The utility model is further elaborated with reference to Figure of description.
Embodiment 1
As shown in Fig. 2 the utility model power transformer enclosure exhaust structure, is installed on the top of fuel tank cap of transformer 8, rise
Current transformer 4 is installed on cover for seat pipe, gear air ring 7 is added below current transformer supporting plate 5, gear air ring 7 is tied to be circular
Structure, made using oil-resisting and heat-resisting rubber thick 1~1.5mm, its external diameter is identical with rise seat internal diameter, the external diameter phase of internal diameter and sleeve pipe
Together；Keep off the bottom of air ring 7 and be provided with exhaust union adaptor 2.
The utility model also has compression dead ring 6, and located at gear air ring 7 bottom, air ring is kept off for compressing, avoids keeping off gas
There is fold when bolt is tightened in circle 7.As shown in figure 4, in the present embodiment, compress and use 5mm thickness high density ultrahards with dead ring 6
Cardboard is made, and for anti-backstop gas, notch at one is provided with ring week, through the notch and 2 pipe UNICOMs of exhaust connection, can prevent gas quilt
The thick spaces of gear air ring 5mm below 7 are blocked in, facilitates the discharge of gas, avoids bubble from focusing on the interior of compression dead ring 6
Side.
Notch can also be two, and such compression dead ring 6 reforms into the combination of two parts curved annular, that is, play pressure
The effect of flat gear air ring 7, and easy to exhaust.
Because gear air ring 7 uses flexible quality of rubber materials, after sleeve pipe is installed, what gear air ring 7 can be tightly is enclosed on
Pipe is outer, so, just keeps off gas below gear air ring 7, and the height of exhaust union adaptor 2 has just been lowered in rise seat naturally
Portion, so as to reach simplified structure design, reduce the purpose of installation difficulty.
Embodiment 2
As shown in figure 3, it is with the difference of embodiment 1：This structure is mainly used in sleeve pipe and largely stretched into fuel tank
The situation in portion.Gear air ring 7 is now arranged on the lower surface of fuel tank cap 8, the external diameter of gear air ring 7 is identical with rise seat internal diameter, internal diameter
Still it is equal to sleeve outer.It can ensure that gas does not enter inside rise seat after sleeve pipe installation gear air ring 7, now, raise the row of seat
Gas union can be cancelled, and enormously simplify the union design of transformer.
In the present embodiment, it may have compression uses dead ring 6, same located at gear air ring 7 bottom, keeps off air ring 7 for compressing, keeps away
Exempt from gear air ring 7 and fold occur when bolt is tightened.Its structure, material are same as Example 1, and notch is one or two.Due to
The present embodiment eliminates exhaust union, and compression is exactly to be vented with fuel tank UNICOM, gas by other of fuel tank with the notch of dead ring 6
Device is discharged.
