Problems solved by technology

Among the traditional 10kV oil-immersed transformers for wind power generation, all of them are oil-immersed transformers with silicon steel sheets as the core, and their own no-load loss is very large, resulting in high energy waste, which does not belong to the category of high energy saving. product
In addition, the 10kV oil-immersed transformers for wind power generation produced today are not fully enclosed, so air pollution will affect the service life of the transformer, resulting in an increase in the operating cost of the transformer, and the degree of intelligence of the transformer is not high enough

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] See figure 1 and figure 2 , the amorphous alloy 10kV oil-immersed transformer for wind power generation of the present invention comprises a body 1, an oil tank 3, a case cover 4 and transformer oil 2, wherein,

[0017] The body 1 is composed of iron core 11 and coil winding 12. The iron core 11 is made of amorphous alloy strip instead of the traditional silicon steel sheet material. Its no-load loss is about 70% lower than that of the silicon steel sheet iron core transformer with the same voltage level and capacity; the iron core 11 is a four-frame and five-column structure; the coil winding 12 is composed of a high-voltage winding 121 and a low-voltage winding 122, the connection group is Dyn11, the voltage level of the high-voltage winding 121 is 10KV or 10.5KV, and the voltage level of the low-voltage winding 122 is 0.69KV, so th...

Abstract

The invention discloses an amorphous alloy 10kV oil-immersed type transformer for wind power generation, wherein the no-load loss of the amorphous alloy 10kV oil-immersed type transformer is 30% of the traditional silicon sheet iron-core transformer. The amorphous alloy 10kV oil-immersed type transformer comprises a transformer body, a tank body and transformer oil, wherein the transformer body comprises an iron core and a coil winding; the tank body comprises an oil tank and a tank cover; the transformer oil is filled in the tank body; the transformer body is installed in the tank body and immersed in the transformer oil; the iron core is made of amorphous alloy material and is in a four-frame and five-post type structure; and the oil tank and the tank cover are welded into a whole to form a fully-closed structure.

Description

technical field [0001] The invention relates to a power transformer, in particular to an amorphous alloy 10kV oil-immersed transformer for wind power generation. Background technique [0002] At present, domestic wind power projects are expanding, so the market demand for such transformers is increasing. Among the traditional 10kV oil-immersed transformers for wind power generation, all of them are oil-immersed transformers with silicon steel sheets as the core, and their own no-load loss is very large, resulting in high energy waste, which does not belong to the category of high energy saving. product. In addition, the 10kV oil-immersed transformers for wind power generation produced today are not fully enclosed, so air pollution will affect the service life of the transformer, resulting in an increase in the operating cost of the transformer, and the intelligence of the transformer is not high enough. Contents of the invention [0003] The purpose of the present invent...
