Abstract

The high-voltage winding comprises a winding body, a high-voltage coil and a high-voltage insulating layer, a wire is wound on the winding body to form the high-voltage coil, the winding body is made of a fiber reinforced composite material, the high-voltage insulating layer wraps the high-voltage coil and the winding body, and the high-voltage insulating layer is made of high-temperature vulcanized silicone rubber. The invention further discloses a dry-type transformer which comprises the high-voltage winding. The high-voltage winding provided by the invention has relatively good fireproof performance, low-temperature resistance, aging resistance and short-circuit test resistance, is excellent in electrical insulation performance, and is energy-saving and environment-friendly.

Description

technical field [0001] The present application relates to the technical field of power transformers, in particular to a high-voltage winding and a dry-type transformer. Background technique [0002] At present, transformers can be divided into: oil-immersed transformers, dry-type transformers, and gas transformers. Dry-type transformers have the advantages of no oil, fire prevention, long life, energy saving, low noise, simple maintenance, safety and reliability. Most of the dry-type transformers currently on the market are dry-type transformers with resin-cast high-voltage windings and open dry-type transformers. Although dry-type transformers have made great progress in the past 10 years, there are still problems such as insulation cracking, poor heat conduction, and harsh operating environments during operation. Contents of the invention [0003] In view of the deficiencies in the prior art, one of the purposes of the present application is to provide a high-voltage w...
