Description

A kind of radiator structure of non-crystaline amorphous metal three-phase stereo transformer
Technical field
The utility model relates to a kind of radiator structure of non-crystaline amorphous metal three-phase stereo transformer.
Background technology
Most of distribution transformers and many power transformers all adopt oil immersed type from cooling.The transformer that capacity is less, smooth tank surface is just enough to by oil cooling but; Intermediate size transformer, tank surface will be made wrinkle shape to increase radiating surface, or installs chip or flat-tube radiator additional, and oil is circulated in radiator; High-power transformer tank surface should add radiator.The cross section of existing three-phase amorphous alloy (silicon steel) leg is all rectangular, and overall structure unshakable in one's determination is mostly four frame pentastyle or three-frame and three poles.These transformers are made rear rectangular cube, therefore radiator is conventionally by rectangle fuel tank be fixed on the fin on fuel tank outer surface, four bights of fuel tank are right angle, therefore also with comparalive ease fin is directly welded on the outer surface of four sidewalls of fuel tank, fin is not established in four bights conventionally, and therefore radiating effect is poor.
Non-crystaline amorphous metal three-phase stereo transformer adopting opening type rolling iron core, iron core is reeled and is formed by the amorphous alloy strips that waits width or Trapezoidal.Coil section and core section adopt the circle of optimal design, make the structure of transformer more compact, not only the stacked four frame pentastyles of volume ratio Same Efficieney capacity or the three-phase transformer of three-frame and three pole are much smaller, and iron loss and copper loss are also lower, are therefore with a wide range of applications.Also to make corresponding radiator for non-crystaline amorphous metal three-phase stereo matched transformer seat for this reason.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art and radiator structure that a kind of non-crystaline amorphous metal three-phase stereo transformer is provided, and it has increased the external cooling area of transformer effectively, thereby has improved the heat-sinking capability of transformer.
The purpose of this utility model is achieved in that a kind of radiator structure of non-crystaline amorphous metal three-phase stereo transformer, comprise transformer body and the radiator around transformer body, described transformer body comprises three-phase iron core and three coils, three-phase iron core is to be formed according to the structures to form of equilateral triangle by three unit iron cores that are closed rectangle frame, three core limbs are respectively to be docked and form mutually by the diameter of cross section of left unit core post of a unit core and the diameter of the cross section of the right unit core post of another unit core, make the cross section of three core limbs all substantially rounded, and the center of circle of the cross section of three core limbs forms an equilateral triangle, three coils are enclosed within on three core limbs correspondingly,
Described radiator comprises a heat radiation oil box and multiple fin; Described heat radiation oil box by three length and highly equal Zhi Bi and three shapes and highly also identical circular arc wall form, and be an equilateral triangular prism casing with three arc chord angles; Multiple described fin are fixed in the outside wall surface of described heat radiation oil box in the consistent mode in interval, fin on the outer surface of some straight walls that are positioned at described heat radiation oil box is vertical with described straight wall fixing, and the fin on the outer surface of some arc chord angles that are positioned at described heat radiation oil box is fixed on the outer surface of arc chord angle in radial mode.
The radiator structure of above-mentioned non-crystaline amorphous metal three-phase stereo transformer, wherein, the fin on the outer surface of each arc chord angle that is positioned at described heat radiation oil box is fixed on the outer surface of arc chord angle in the mode vertical with the tangent line of the outer surface of corresponding arc chord angle.
The technical scheme of the radiator structure of non-crystaline amorphous metal three-phase stereo transformer of the present utility model, the shape of heat radiation oil box adopts the equilateral triangular prism casing approaching with the profile of transformer body, and at the outer surface at Zhi Bi position and the outer surface at arc chord angle position uniform fixing multiple fin respectively of heat radiation oil box, effectively increase the external cooling area of transformer, thereby improved the heat-sinking capability of transformer.
Brief description of the drawings
Fig. 1 is the schematic diagram of the radiator structure of non-crystaline amorphous metal three-phase stereo transformer of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, the radiator structure of a kind of non-crystaline amorphous metal three-phase stereo transformer of the present utility model, comprise transformer body 1 and the radiator 2 around transformer body 1, transformer body 1 comprises three-phase unshakable in one's determination 11 and three coils 12, wherein, three-phase iron core 11 is to be formed according to the structures to form of equilateral triangle by three unit iron cores that are closed rectangle frame, three core limbs are respectively to be docked and form mutually by the diameter of cross section of left unit core post of a unit core and the diameter of the cross section of the right unit core post of another unit core, make the cross section of three core limbs all substantially rounded, and the center of circle of the cross section of three core limbs forms an equilateral triangle, three coils 12 are enclosed within on three core limbs correspondingly.
Radiator 2 comprises the fin 22 that a heat radiation oil box 21 is identical with multiple shapes and thickness; Wherein, heat radiation oil box 21 by three length and highly equal Zhi Bi and three shapes and highly also identical circular arc wall form, and be an equilateral triangular prism casing with three arc chord angles; Multiple fin 22 are fixed in the outside wall surface of heat radiation oil box 21 in the consistent mode in interval.Fin 22 on the outer surface of some straight walls 211 that are positioned at heat radiation oil box 21 is vertical fixing with the outer surface of straight wall 211, and the fin 22 on the outer surface of some arc chord angles 212 that are positioned at heat radiation oil box 21 is fixed on the outer surface of arc chord angle 212 in radial mode.
Best execution mode is, the fin 22 on the outer surface of each arc chord angle 212 that is positioned at heat radiation oil box 21 is fixed on the outer surface of arc chord angle 212 in the mode vertical with the tangent line of the outer surface of corresponding arc chord angle 212.
Due to the position of three arc chord angles 212 of heat radiation oil box 21 and the position of three coils 12 of transformer body 1 corresponding, the namely the strongest position of heating, therefore fin 22 arrangements of these three arc chord angles 212 need intensive, and the position of the middle part off-line circle of three straight walls 211 of heat radiation oil box 21 is far away, the heating at these three positions is relatively not strong, therefore can save several fin in the middle part of three straight walls 211, spillage of material can be reduced on the one hand, the weight of transformer can be reduced on the other hand.
The radiator structure of non-crystaline amorphous metal three-phase stereo transformer of the present utility model, the shape of heat radiation oil box adopts the equilateral triangular prism casing approaching with the profile of transformer body, and at the outer surface at Zhi Bi position and the outer surface at arc chord angle position uniform fixing multiple shapes and the identical fin of thickness respectively of heat radiation oil box, effectively increase the external cooling area of transformer, thereby improved the heat-sinking capability of transformer.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
