Supporting bar favorable for dissipating heat of oil-immersing amorphous alloy transformer

Abstract

The invention belongs to the technical field of amorphous alloy iron core manufacturing, and particularly relates to a supporting bar favorable for dissipating heat of an oil-immersing amorphous alloy transformer. Temperature rising of the transformer is reduced through optimizing the oil-immersing amorphous alloy transformer. The supporting bar comprises supporting bar bodies, glue applying straps are connected to the lower surfaces of the supporting bar bodies, and the number of the glue applying straps is more than one. The thickness of the supporting bar bodies in an oil channel of the transformer is increased, the area of the oil channel can be increased, the supporting strength of the supporting bar bodies is improved, a breakdown voltage is increased, and the heat dissipating effect of the transformer is improved. The two narrow-piece glue applying straps are adopted to paste a fence-type structure of the supporting bar bodies, not only is full contact between oil and copper wires facilitated and thus is the temperature rising of the transformer reduced, but also machining difficulty of the transformer is favorable for being reduced, the transformer can be machined faster and more conveniently, and the temperature of the transformer is lowered. Thus, the remarkable advantages that the heat dissipating coefficient is improved and the temperature rising of the transformer is reduced are achieved, and the supporting bar is simple and reasonable in structure, obvious in effect and favorable for being widely promoted and applied.

Description

technical field [0001] The invention belongs to the technical field of amorphous alloy iron core manufacturing, and in particular relates to a stay that facilitates the heat dissipation of an oil-immersed amorphous alloy transformer, and reduces the temperature rise of the transformer by optimizing the structure of the oil-immersed amorphous alloy transformer. Background technique In the 1990s, amorphous alloy transformers were gradually introduced into my country's power market as a high-efficiency and energy-saving product. It used amorphous alloy materials instead of silicon steel sheets to manufacture transformers. Amorphous alloy coil oil passages and main air passages generally use stays or stay curtains. The stay curtain is usually a whole piece of glued paper glued in parallel to several stays, which will cause a piece of glued paper between the oil channel and the copper wire, which will cause poor heat dissipation and increase the temperature rise of the transfor...
