The invention discloses a high-voltage coil of an oil-immersed transformer. The high-voltage coil of the oil-immersed transformer comprises a shell, a high-voltage coil body and an outlet port. The high-voltage coil body surrounds the inner periphery of the shell and is connected with the outlet port. The outlet port is a recessed screw hole type outlet port, and the high-voltage coil body is of an elliptical structure. The high-voltage coil has the advantages that the production difficulty, the production cost and abrasion on the transformer can be reduced, energy can be saved, and environments can be protected.
Description
[0001] technical field [0002] The invention relates to power transmission and transformation equipment, in particular to an oil-immersed transformer high-voltage coil. Background technique [0003] Transformer is an important equipment in power transmission and transformation equipment. It is in an extremely important low position in the power grid. It is the main equipment to ensure social production and consumption of electricity. The structure and material of the transformer directly affect the quality and safety of power supply. The traditional transformer high-voltage coil It is circular, which increases the difficulty of manufacturing, and the transformer is empty and the load loss is relatively high. Contents of the invention [0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an oil-immersed transformer high-voltage coil. [0005] Technical solution: A high-voltage coil of an oil-immersed tran...
