Further, described blender is provided with two, and described oil pipe includes oil pipe and lower oil pipe, and described blender is separately positioned on one end of the corresponding shell of oil pipe and one end of the corresponding cooling shell of lower oil pipe.
Oil pipe is arranged to upper oil pipe and lower oil pipe, blender is separately positioned on to upper oil pipe and lower oil pipe place, can make hot transformer oil enter in the middle of cooler time, when cold transformer oil enters into shell, all can drive blender to rotate, also make the central transformer oil of shell stir fast, the central coil windings of shell and the temperature of iron core can be declined fast simultaneously.
Further, on described puddler, be provided with stirring piece.
Stirring piece is set on blender, can increases puddler and can drive the flow of liquid in the process stirring, in the process stirring at liquid, ensured the mixing effect of puddler.
Further, on described cooler, be also provided with corrugate fin.
Corrugate fin is set on cooler, can makes to enter the transformer oil in the middle of cooler, cooling fast by corrugate fin, guarantee the normal heat radiation of transformer, make the work that transformer can be lasting.
The utility model has the advantage of: utilize the hot transformer oil to move to drive blender to stir to cold transformer oil, accelerated mixing of heat transformer oil and cold transformer oil, make the oil temperature decline of transformer oil become rapider.
