On be provided at least one oil groove, be conducive to the circulation of transformer oil, without change transformer oil original circulation path,
It is just not necessarily to change the original structure of transformer, is conducive to the stable operation of transformer, moreover, the preparation of entire resistance to shorting transformer
Technique obtains very big simplification；Finally, due to which transformer oil can normally circulate, it will not influence transformer and normally cool down.
In order to simplify preparation process, as a kind of improvement to above-mentioned resistance to shorting transformer, the oil groove is provided with insulation
The side of the close coil windings of plate.
It is improved as the another kind to above-mentioned resistance to shorting transformer, the oil groove is opened along coil windings axis extending direction
If.
As another improvement to above-mentioned resistance to shorting transformer, each oil groove interval setting.
In order to fix insulation board, as another improvement to above-mentioned resistance to shorting transformer, the separate line of the insulation board
The side of circle winding is provided at least one for fixing groove for being fixed on insulation board on transformer core, embedding in the fixing groove
There is fixed steel band, the channel steel folder of the transformer core is equipped with other screw rod, and the fixed steel band is fixedly connected with other screw rod.
As the further improvement to above-mentioned resistance to shorting transformer, the fixing groove is along perpendicular to the coil windings axis
The direction of line extending direction opens up, and the other screw rod is arranged along the coil windings axis extending direction.
As the further improvement to above-mentioned resistance to shorting transformer, the insulation board is plank.
As the further improvement to above-mentioned resistance to shorting transformer, the plank is laminated wood.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
The present invention will be further described in detail for embodiment.
In conjunction with Fig. 1, Fig. 2, Fig. 3, the resistance to shorting transformer 1 of the utility model includes: transformer core 8 and wound on transformation
Coil windings 4 on device iron core 8；An insulation board 2 is respectively fixedly installed on the outside of the both ends of coil windings 4；On each insulation board 2
It is provided at least one oil groove 5 (such as 6) for circulating for transformer oil.
Due to being provided at least one oil groove on each insulation board, is conducive to the circulation of transformer oil, becomes without change
Original circulation path of depressor oil is also just not necessarily to change the original structure of transformer, is conducive to the stable operation of transformer, and
And the preparation process of entire resistance to shorting transformer obtains very big simplification；Simultaneously because transformer oil can normally circulate, can disappear
Except because increasing influence of the insulation board to coil windings temperature rise, transformer can normally cool down.
In order to simplify preparation process, oil groove 5 is provided with the side of the close coil windings 4 of insulation board 2；As other implementations
Mode, if insulation board 2 is sufficiently thick, oil groove 5 can be provided with the inside of insulation board 2.
The present embodiment, oil groove 5 are opened up along the axis extending direction of coil windings 4；As other embodiments, oil groove 5
It can be accordingly arranged according to the arrangement of the circulation duct of transformer oil.
The present embodiment, the setting of each interval of oil groove 5；As other embodiments, the gap size between oil groove 5 can be according to need
It adjusts.
In order to fix insulation board 2, at least one is provided with for that will insulate in the side of the separate coil windings 4 of insulation board 2
Plate 2 is fixed on the fixing groove 3 (such as 2) on transformer core 8, and fixed steel band 7 is embedded in fixing groove 3, transformer core 8
