Abstract
The utility model discloses a structure for reducing the temperature rising of an amorphous alloy oil immersed transformer, which comprises a coil, radiators and an oil duct. The radiators are positioned at both sides of the coil; the distance L between the height center point of the coil and the height center point of each radiator is 90 mm; the radiators are corrugated radiators or plate radiators; the oil duct is arranged in the coil; the oil duct is a fence structure formed by adhering a plurality of stays by adhesive tapes; and each stay has the thickness of 4.5mm. According to the utility model, by drawing away the distance L between a heating center and each heat dissipation center by 90mm, the up-and-down circulating distance of oil is increased and the structure is more beneficial for dissipating the heat of the oil by the heat dissipation area of an oil tank; and the thickness of a stay is changed into 4.5mm from the original thickness of 3mm and the stays are directly adhered by the narrow adhesive tapes, so that the heat dissipation coefficient is greatly improved and the temperature of the transformer is reduced by 4 to 6 DEG C. The structure disclosed by the utility model is simple, is more convenient and more time-saving to process and is very suitable for the amorphous alloy oil immersed transformer.
Description
Technical field
The utility model relates to the manufacturing technology field of amorphous alloy iron core, a kind of specifically structure that reduces the temperature rise of amorphous alloy oil immersion type transformer.
Background technology
The amorphous alloy oil immersion type transformer is the energy-saving product of in time releasing according to market demand; Instead silicon steel plate core transformer is used for outdoor or indoor distribution network system; Main insulation between the high-voltage coil and low-voltage coil of tradition oil immersed type amorphous alloy transformer generally all is to adopt oil channel structure, and general oil duct width is more than 10mm.Though this oil channel structure can guarantee the temperature rise and the insulation property of transformer, because the oil channel structure width is bigger, cause the product each side to have the waste of material problem, cost is high.Simultaneously general oil duct all is to be stained with some stays by a whole some gummed paper, makes oil and copper cash also across a some gummed paper like this, and coefficient of heat transfer is given a discount, and radiating effect is not good.
Summary of the invention
In order to solve the deficiency of prior art; The utility model provides a kind of structure that reduces the temperature rise of amorphous alloy oil immersion type transformer; Through improving coil height central point and the distance of radiator height central point and the thickness and the bonding method of stay, reach the raising coefficient of heat transfer, reduce the effect of temperature rise.
The technical scheme of the utility model is: a kind of structure that reduces the temperature rise of amorphous alloy oil immersion type transformer; Comprise coil, radiator, oil duct; It is characterized in that: said radiator is positioned at the both sides of coil; The distance of coil height central point and radiator height central point is 90mm, is provided with oil duct in the coil, the fence structure that oil duct becomes through adhesive tape sticking for several pieces stays.
Described radiator is ripple radiator or gilled radiator.
The thickness of described stay is 4.5mm.
The beneficial effect of the utility model is: 90mm is drawn back with the distance L at heat radiation center in the center that will generate heat, the corresponding corrugated plate width that dwindles, and the cycling distance up and down of oil increases; The heat that is more conducive to oil is through the heat radiation of fuel tank area of dissipation; And the thickness of stay changes to 4.5mm by original 3mm, directly with the stay that tapes up of arrow gauge, improves coefficient of heat transfer greatly; And process more convenient, more save time, can make the temperature of transformer reduce the 4-6 degree.

Fig. 1 is the structural representation of the utility model.
The structural representation of the said oil duct of Fig. 2 the utility model.
The schematic cross-section of the said oil duct of Fig. 3 the utility model.
Wherein, 1-coil, 2-radiator, 3-oil duct, 4-coil height central point, 5-radiator height central point, 6-stay, 7-adhesive tape.
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
As shown in Figure 1; A kind of structure that reduces the temperature rise of amorphous alloy oil immersion type transformer; Comprise coil 1, radiator 2, radiator 2 is positioned at the both sides of coil 1, and coil height central point 4 is 90mm with the distance L of radiator height central point 5; In the utility model, radiator 2 is ripple radiator or gilled radiator.Be provided with oil duct 3 in the coil 1, like Fig. 2, shown in Figure 3, the fence structure that oil duct 3 is pasted through adhesive tape 7 for several pieces stays 6, the thickness of stay 7 is 4.5mm.
In the utility model; After the distance L of coil height central point 4 and radiator height central point 5 was designed to 90mm, stay 7 width changed to 4.5mm by original 3mm, and can make goes rancid becomes more unimpeded; Can let oil more the heat of coil brought out; Area of dissipation through fuel tank sheds again, and temperature rise can descend 2 to 4k, i.e. temperature 2 to 4 degree that can descend.
The utility model improves oil duct, and directly the adhesive tape 7 with arrow gauge is stained with stay 6, improves coefficient of heat transfer greatly, and process more convenient, more save time, temperature rise can descend 1 to 2k be temperature can descend 1 to 2 the degree.
Principle that the utility model just is described and the most preferred embodiment described in the foregoing description and the specification; Under the prerequisite that does not break away from the utility model spirit and scope; The utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.
