Abstract
The utility model discloses an amorphous single-phase oil-filled distribution transformer. The transformer comprises an oil tank consisting of walls and a cover, a transformer body arranged in the oil tank, and transformer oil filled around the transformer body. The transformer is characterized in that the transformer also comprises a pressure relief valve, a hollow chamber is arranged between the upper surface of the transformer oil and the bottom of the cover, the pressure relief valve is positioned on the side of the hollow chamber, and the single-phase transformer body comprises amorphous alloy iron cores and transformer coils. The utility model has the advantage that the transformer can prevent the coil temperature from rising and thus avoid the deformation or burst of the oil tank caused by the expansion of the transformer oil under high temperature. This is because the transformer body adopts the amorphous iron core structure and a pressure relief valve is provided on the side of the oil tank.

Background technology
Present oil immersed type single phase distribution transformer, the general cold-reduced silicon sheet that adopts unshakable in one's determination becomes the silicon steel sheet continuous reeling " O " sections heart of a sealing mostly as permeability magnetic material, and the cross section of core limb is rounded.Should two core limbs be arranged " O " sections heart, coil of difference coiling on each core limb, each coil is made up of high-voltage coil and low-voltage coil, and the cross section of coil is rounded.By " O " sections heart and two device bodies that coil is formed, be fixed in the fuel tank that is full of transformer oil, generally do not adorn pressure relief valve.Its shortcoming is that no-load loss is higher, in running, and particularly when distribution line or transformer itself break down, because coil temperature raises, the transformer oil volumetric expansion, the pressure in the fuel tank can increase sharply, and makes fuel tank produce distortion or explosion phenomenon.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of energy-saving amorphous alloy single-phase oil immersion type distributing transformer that can prevent fuel tank to produce distortion or explosion phenomenon at the defective that above-mentioned prior art exists.
For solving the problems of the technologies described above, the utility model adopts a kind of amorphous alloy single-phase oil immersion type distributing transformer, comprise the fuel tank that constitutes by tank wall and case lid, be located at the transformer body in the fuel tank and be filled in transformer oil around the transformer body, wherein, also comprise a pressure relief valve, leave cavity between described transformer oil upper surface and the case lid bottom surface, described pressure relief valve is located on the tank wall that is positioned at cavity, and described single-phase transformer device body comprises amorphous alloy core and transformer coil.
Above-mentioned amorphous alloy single-phase oil immersion type distributing transformer, wherein, described amorphous alloy core is the iron core frame that an end can open and close, the cross section of the core limb of this iron core frame is rectangular.
Above-mentioned amorphous alloy single-phase oil immersion type distributing transformer, wherein, described transformer coil is by low-voltage coil and be wound on the whole coil that the outer high-tension coil of low-voltage coil constitutes.
Above-mentioned amorphous alloy single-phase oil immersion type distributing transformer, wherein, described transformer body is formed by two amorphous alloy cores and a transformer coil, described two amorphous alloy cores are measure-alike and be set up in parallel, and described transformer coil is nested with on the adjacent core limb of two amorphous alloy cores arranged side by side.
Above-mentioned amorphous alloy single-phase oil immersion type distributing transformer, wherein, institute's transformer body is formed by an amorphous alloy core and two transformer coils, described two transformer coils are sleeved on the core limb of amorphous alloy core separately, and leave effective gap between adjacent two coils.
Above-mentioned amorphous alloy single-phase oil immersion type distributing transformer, wherein, described two amorphous alloy cores arranged side by side leave effective gap between two adjacent frame posts.
The utility model has the advantages that:, can provide kind of an energy-saving single-phase oil immersion type distributing transformer because transformer body has adopted amorphous alloy core; Because the cavity at pressure relief valve and fuel tank top is set on the tank wall of fuel tank, can prevent to raise when coil temperature again, after the transformer oil volumetric expansion, fuel tank produces the phenomenon of distortion or explosion.
