Abstract

The invention discloses a wind power generator set and a vane deicing device thereof. The vane deicing device comprises an electric heating element mounted on a vane, the electric heating element comprises a carbon-fiberglass hybrid fabric and electrode components, the carbon-fiberglass hybrid fabric comprises a carbon fiber group in a vane length direction, a carbon fiber group in a vane chord length direction and fiberglass bundles, and the carbon fiber group in the vane length direction, the carbon fiber group in the vane chord length direction and the fiberglass bundles are woven together.The electrode components are mounted at two ends of each carbon fiber bundle of one of the carbon fiber group in the vane length direction and the carbon fiber group in the vane chord length direction. By the vane deicing device, vanes can be deiced effectively, misplacement of the carbon fiber bundles is prevented, and faults such as fiber intertwining and short circuit can be avoided.

Description

technical field

[0001] The invention relates to the field of wind power generation, and in particular, the invention relates to a device for defrosting blades of a wind power generating set. Background technique

[0002] Wind turbines in some areas will face extreme weather such as frost, cold wave, and freezing rain during the cold period, resulting in ice-covered, frost-covered, and snow-covered blades. These phenomena will directly change the surface and cross-sectional shape of the blade, reduce the efficiency of the blade to absorb wind energy, cause mechanical damage to the unit, increase the load of the unit, and shift the center of gravity. At the same time, ice falling off poses a safety hazard to on-site personnel and on-site equipment. In addition, icing and snow on the blades will also affect the accuracy of wind measurement, and bring serious economic loss of power generation to the wind farm. The cumulative number of ice-covered days in a wind farm in Gansu fr...

Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the present invention, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] refer to figure 1 , shows the electric heating element of the blade deicing device according to the embodiment of the present invention. exist figure 1 In , the horizontal direction is called the blade length direction, and the vertical direction is called the blade chord length direction based on the position where the heating element is installed on the blade. Although this is defined here, in actual assembly, the electric heating element can be turned 90 degrees to lay, so that the horizontal direction and the vertical direction can be interchanged, and are not limited to the fixed orientation here.

[0032] According to an embodiment of the present invention, a blade deicing device for deicing blades is provided. Generally, the blade deicing de...
