Abstract

The invention provides a built-in transformer of a wind power tower barrel, comprising a low-voltage winding, a high-voltage winding and an iron core. The structural key points are as follows: the iron core is provided with an upper iron yoke and a lower iron yoke; a side column is respectively arranged between the left end and the right end of the upper iron yoke and the lower iron yoke; the upper and lower ends of the side column are respectively connected with the left end and the right end of the iron yoke in an overlapping manner; the middle part of the iron yoke is provided with a middle column; the upper end and the lower end of the middle column are respectively connected with the middle part of the iron yoke in an overlapping manner; the side column and the middle column are respectively provided with the winding; the inner layer of the winding is provided with low-voltage coil; the outer layer of the low-voltage coil is sheathed with a high-voltage coil; clamping units are respectively arranged at the front and rear sides of the iron yoke; the low-voltage coil is wound with a copper foil; the materials pre-impregnated by DMD resin is used as the insulation between layers; a flexible grid cloth is arranged between two adjacent layers of the high-voltage winding; and the periphery of the high-voltage is provided with the solventless grid materials. The invention is characterized by compact structure, long service life, low noise, free maintenance, high reliability, no pollution, flame retardancy and the like, the probability of partial discharge is approximately zero, and the invention can be recycled after the service life is ended up.

Description

technical field [0001] The invention relates to a transformer, in particular to an epoxy resin casting dry-type transformer with superior performance and novel structure, which is used for the built-in tower of the main wind power generator, and belongs to the technical field of wind power equipment. Background technique [0002] Since the energy crisis, people's awareness of green environmental protection has been strengthened, the world's wind power industry has developed rapidly, the installed capacity has increased rapidly, and the wind power industry has continued to expand. Wind energy is a non-toxic, non-polluting renewable energy. At present, my country's wind power has been developing rapidly. It is estimated that my country's wind power installed capacity will reach 55 million KW in 2010 and 112 million KW in 2020. It can be seen that wind power has a bright future. Expansion capacity. [0003] Due to the small capacity of the single unit of the generating set, th...
