Structure between high-tension coil and low-tension coil in transformer

Abstract

The invention relates to a structure between a high-tension coil and a low-tension coil in a transformer, which comprises a high-tension coil and a low-tension coil; an insulating paper board is arranged between the high-tension coil and the low-tension coil; the high-tension coil and the low-tension are of elliptic structures; and the high-tension coil, the low-tension coil and the insulating paper board are formed integrally. The structure between the high-tension coil and low-tension coil in the transformer provided by the invention has the advantages of decreasing the materials of iron cores, and reducing the no-load loss of the transformer.

Description

technical field [0001] The invention relates to a transformer, in particular to a structure between high and low voltage coils in a dry type transformer. Background technique [0002] A transformer is a static electrical appliance. Using the principle of electromagnetic induction to convert one level of voltage and current into another level of voltage and current with the same screen rate between two or more coils, and transmit electric energy. [0003] The coil of the transformer constitutes the circuit part of the equipment itself. It is directly connected to the external power grid and is the most important part of the transformer. The coil is often compared to the "heart" of the transformer. [0004] The coil is the basic part of the transformer to transform the voltage. The coil is composed of different turns. Since the voltage of each turn of different coils is the same, it is necessary to make the coil have different turns to achieve different voltages. [0005] Wh...

Problems solved by technology

In this way, the size of the coil is too large, and the connection between the high-voltage coil and the low-voltage coil is not well tightened, and the noise will be too large when the transformer is running.
