Abstract
The utility model discloses an amorphous alloy transformer coil structure. The coil structure comprises a rectangular high-voltage coil and a rectangular low-voltage coil, wherein the high-voltage coil is wound outside the low-voltage coil; heat dissipation oil passages are formed by respectively separating two adjacent layers of low-voltage copper foils between the long sides of the two sides of the low-voltage coil through a plurality of stays arranged at intervals; and a cardboard is arranged on the inner surface of one low-voltage copper foil arranged outside one heat dissipation oil passage so as to enable the external ends of the stays to be propped against the inner surfaces of the low-voltage copper foils arranged outside the heat dissipation oil passages. According to the coil structure provided by the utility model, flexural strength of the low-voltage copper foils can be enhanced when the transformer is short-circuited suddenly, so that the widths of the heat dissipation passages are even, and accordingly, the transformer can meet the temperature rise requirement.
Description
Technical field
The utility model belongs to field transformer, relates to a kind of loop construction of amorphous alloy transformer.
Background technology
The mounting coil of general amorphous alloy transformer is on the amorphous alloy stem stem, and low-voltage coil is at internal layer, and high-tension coil is sleeved on the low-voltage coil skin, so that insulation.Centre at low-voltage coil also is provided with the heat radiation oil duct that is divided into by some stays.Because when transformer generation sudden short circuit, low-voltage coil can produce very large electric power, the low pressure Copper Foil of coiling low-voltage coil 1 can shrink to coil is inboard.Because the thinner thickness of low pressure Copper Foil 3, bending strength is not very large, therefore the gap of adjacent two bracing bars 21 in heat radiation oil duct 2 can be caused low pressure Copper Foil 3 to curve inwardly and is out of shape (see figure 1), the width that makes heat radiation oil duct 2 is inhomogeneous and affect heat sinking function, can not satisfy the temperature rise requirement of transformer.
Summary of the invention
The purpose of this utility model provides a kind of loop construction of amorphous alloy transformer, and it can strengthen the bending strength of low pressure Copper Foil when the transformer sudden short circuit, and then can not make the width of heat radiation oil duct inhomogeneous, makes transformer can satisfy the temperature rise requirement.
The technical scheme that realizes above-mentioned purpose is: a kind of loop construction of amorphous alloy transformer, comprise the high-tension coil of rectangular configuration and the low-voltage coil of rectangular configuration, described high-tension coil is outside low-voltage coil, the centre on two face length limits of described low-voltage coil separates to form heat radiation oil duct by some spaced apart stays with the low pressure Copper Foil of adjacent two layers respectively, wherein, on the inner surface of the low pressure Copper Foil that is positioned at every described heat radiation oil duct outside, a cardboard is set also so that the outer end of described stay by described cardboard support on the inner surface of the low pressure Copper Foil that is positioned at every described heat radiation oil duct outside.
The loop construction of above-mentioned amorphous alloy transformer, wherein, described cardboard is bonded together with the inner surface of the described low pressure Copper Foil that is positioned at the described heat radiation oil duct outside.
The loop construction of amorphous alloy transformer of the present utility model, employing arranges cardboard in the heat radiation oil duct of low-voltage coil, can when the transformer sudden short circuit, strengthen the bending strength of the low pressure Copper Foil that is positioned at the heat radiation oil duct outside, and then the width that can not make heat radiation oil duct is inhomogeneous and affect heat sinking function, can the temperature rise requirement thereby can satisfy transformer.In addition, because the cost of cardboard is relatively low, so operability is extremely strong, so it is high to implement efficient.

Fig. 2 is the partial cross section view of the loop construction of amorphous alloy transformer of the present utility model.
Embodiment
In order to make those skilled in the art can understand better the technical solution of the utility model, below in conjunction with accompanying drawing its embodiment is described in detail:
See also Fig. 2, the loop construction of a kind of amorphous alloy transformer of the present utility model, comprise the high-tension coil (not shown) of rectangular configuration and the low-voltage coil 1 of rectangular configuration, wherein, high-tension coil is outside low-voltage coil 1, and the centre on two face length limits of low-voltage coil 1 is respectively equipped with heat radiation oil duct 2.Heat radiation oil duct 2 is by some spaced apart stays 21 the low pressure Copper Foil 3,3 ' of adjacent two layers to be separated formation, one cardboard 4 also is set on the inner surface of the low pressure Copper Foil 3 ' that is positioned at every heat radiation oil duct 2 outsides, this cardboard 4 is to be bonded in securely on the inner surface of low pressure Copper Foil 3 ' in heat radiation oil duct 2 outsides by binding agent so that the outer end of stay 21 by cardboard 4 supports on the inner surface of the low pressure Copper Foil 3 ' that is positioned at every heat radiation oil duct 2 outsides.
The loop construction of amorphous alloy transformer of the present utility model can increase the low pressure Copper Foil 3 ' in heat radiation oil duct 2 outsides that are positioned at low-voltage coil 1 in the bending strength of the gap of two adjacent stays 21, also increased simultaneously the anti-electrodynamic intensity of low pressure Copper Foil when running into sudden short circuit, and then the width that can not make heat radiation oil duct is inhomogeneous and affect heat sinking function, can the temperature rise requirement thereby can satisfy transformer.In addition, because the cost of cardboard is relatively low, so operability is extremely strong, so it is high to implement efficient.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
