Description
Technical field：
The invention belongs to field transformer, more particularly to a kind of new easily cooling transformer oil case.
Background technology：
It is known that transformer is widely used in production, transformer is to be handed over using the principle of electromagnetic induction to change
The device of voltage is flowed, fuel tank is the important component in transformer, and oily poor fluidity in existing fuel tank, cooling effect is not
It is good.
" bell-jar " oil tank of transformer includes upper oil tank and lower oil tank, and " groove profile bottom " is used in lower oil tank more.
The characteristics of " groove profile bottom " is that bottom portion is elongated slot, is only put into lower yoke part, and case is larger along area, and winding is placed in case along plane
On.This structure is advantageous to winding bottom and fixed, and reduces the dosage of transformer oil.But because case between bottom along with hanging
Empty position is larger, it is necessary to support is strengthened in many places, mixes for structure on lower oil tank especially for hanging, is mixed due to hanging
Be responsible for the weight of whole transformers, hang mix strengthen support section it is increasingly complex.
At present, conventional lower oil tank, which is hung, mixes use and " carries a sedan " formula structure, i.e., is welded with elongated channel-section steel in lower oil tank bottom,
Boatswain chair is welded in channel-section steel both ends, and for hanging axis string on boatswain chair, composition, which is hung, mixes structure.The deficiency of this structure is that channel-section steel paves fuel tank,
Add fuel tank height.During handling, mainly it is forced through to hang to mix and is delivered on elongated channel-section steel, forms by Force system, " groove profile case
Bottom " primarily serves Sheng oil effect, and very little is acted in terms of structural strength, causes each several part stress distribution uneven.
Therefore, for above-mentioned technical problem, it is necessary to a kind of new easily cooling transformer oil case of new structure is provided, with
Solve the problems of the prior art.

There are top groove and bottom groove, the top of the fuel tank main body is provided with and top groove shape identical cooling chamber, the bottom
The lower section of portion's groove is provided with fixed plate, and the fixed plate is bolted on base, and lifting machine is welded with the base
Structure, the derricking gear include four, each derricking gear include bottom plate, the first supporting plate with the first hole, with
Second supporting plate, the connecting tube through the first hole and the second hole in the second hole, the connecting tube and the first supporting plate and second
Fagging is by being welded and fixed, and the first end of the connecting tube is welded with baffle plate, and the second end side of the connecting tube, which is provided with, to be welded on
Two pieces of stiffener plates in second supporting plate, first supporting plate, the second supporting plate and two pieces of stiffener plates are welded in
On bottom plate, the first end of the connecting tube extends the side wall of base.
Further, the top groove is circular arc.
Further, the bottom groove is rounding arc.
Further, integrally formed multiple strengthening rib strips in the side wall of the fuel tank main body.
Further, the trapezoidal shape of the strengthening rib strip.
The present invention has the advantages that：The new easily cooling transformer oil case of the present invention is easy to oil stream to move by setting
Structure, strengthen cold and hot oily mobility, strengthen cooling effect, wherein derricking gear is arranged on the place on the case edge of fuel tank, drops
Low fuel tank height, derricking gear do not use channel-section steel, reduce the weight of fuel tank, save material, set in upper and lower both direction
Hoisting structure is put, preferably fuel tank can be lifted.
