Problems solved by technology

[0012] This is a problem unique to transformers installed inside the towers of wind power generation equipment. If this problem is not solved, it will be difficult to reduce the air temperature around the transformers inside the towers.
[0013] However, Patent Document 1 does not involve the structure of the transformer at all, and it is obvious that the above-mentioned problems have not been recognized.

Embodiment Construction

[0061] Hereinafter, embodiments of the wind power generation facility of the present invention will be described in detail using the drawings.

[0062] figure 1 , figure 2 and image 3 The first embodiment of the wind power generation facility of the present invention is shown. As shown in these figures, the general structure of the wind power generation equipment of the present embodiment includes: a tower 3 built on the foundation; a wind deflector 25 arranged on the top of the tower 3; ) ; blades 26 connected to the generator and generating electric power by rotating the generator; and transformer 1 installed on the foundation inside the tower 3 and transforming the power generated by the generator.

[0063] Such as figure 2 and image 3 As shown, the transformer 1 installed on the foundation inside the tower 3 is formed such that an iron core (not shown) and an excitation coil (not shown) assembled on the iron core are housed in the ribbed corrugated cooling box 2. ...

Abstract

The present invention relates to a wind turbine power generating facilities. A hood in a tower receives air having absorbed heat released from a corrugated rib tank. The hood is set above the corrugated rib tank of a transformer being installed on a foundation in the interior of a tower and transforming electric power generated by an electric generator. An exhaust duct, which discharges the air having absorbed heat released from the corrugated rib tank and flowing into the hood, is provided to the interior of the tower so as to be connected to the hood and extend upward up to the upper portion of the tower.

Description

technical field [0001] The present invention relates to a wind power plant, in particular to a wind power plant suitable for having a transformer inside a tower with a power generating device on top. Background technique [0002] Generally, a wind power generation facility builds a tower on the ground, and a spinner is installed on the top of the tower. A rotor having blades is connected to a generator inside the spinner, and the blades are rotated by the wind to generate electricity from the generator. In addition, there are also power equipment such as transformers that can transform the power generated by the generator to be supplied to the power system, and converters that convert the power into DC or AC. [0003] These devices have been installed in a separate building from the tower in the past, but in recent years, there is a tendency to make wind power generation equipment that houses power equipment such as transformers inside the tower without requiring a separate ...
