Problems solved by technology

Ordinary transformer coils mainly lay a circle of hollow stays in the coil for air circulation heat dissipation. This heat dissipation method not only can only dissipate heat for several layers of coils adjacent to the stays, but does not take into account the outermost layer or The innermost coil, and if some stays are deformed and block the airway due to the local force of the transformer, the temperature of a certain part of the coil will rise sharply, which will affect the continuous use of the entire transformer, and even cause a fire if it is more serious , so how to dissipate heat from high-voltage coils and low-voltage coils is extremely important

Abstract

The invention discloses a coil winding of an ocean platform transformer. The coil winding comprises an iron core column, low-voltage coils and high-voltage coils, wherein the iron core column is cylindrical, the surface of the iron core column is sleeved with a low-voltage insulating cylinder, the low-voltage insulating cylinder is wound with multiple layers of low-voltage coils, four low-voltageair duct plates are further arranged in the low-voltage coils, the outermost layer of the low-voltage coil is sleeved with a high-voltage insulating plate, the high-voltage insulating plate is wound with multiple layers of high-voltage coils, three high-voltage air duct plates are arranged in the high-voltage coils, and epoxy resin is poured to the low-voltage coils and the high-voltage coils. According to the coil winding, uniform heat dissipation can be realized among the low-voltage coils and the high-voltage coils, and air ducts of the air duct plates are of a staggered structure, so thatheat dissipation of a certain blocked air duct is not influenced; and meanwhile, the surface of the coil winding is coated with a layer of nano-material, so that the transformer does not discharge along a dielectric surface in a high-mildew environment.

Description

Technical field [0001] The invention relates to the field of power equipment, in particular to a coil winding of an offshore platform transformer. Background technique [0002] In recent years, offshore oil exploration has made great progress, and offshore oil exploration technology has gradually improved, which has gradually increased the oil production of a single platform. Most of the equipment in oil extraction equipment is powered by electric energy, so the transformer is particularly important in the oil extraction process. However, the complex environment of the ocean determines that the performance requirements of transformers dedicated to offshore platforms are relatively high, especially the heat sink of the transformer. The speed of heat dissipation directly determines the continuous working time of the transformer. The transformer coil is one of the most important parts of the transformer structure and the component that generates the most heat in use, so the degree ...
