Problems solved by technology

As far as the laying position of the lightning protection wire is concerned, the current lightning protection wire is fixed in the middle of the web of the blade through iron riding horses, putty (composed of talc powder and resin), and pasted cloth. This structure prolongs the working time during the manufacturing process on the one hand. , Increase material costs, and at the same time, the cloth layer will fall off during the subsequent operation of the blade, resulting in loose wires

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] figure 1 It is a structural schematic diagram of the lightning protection device of the blade of a wind power generating set in the prior art; the lightning protection wire is fixed in the middle of the web of the blade through iron riding, putty (talcum powder and resin composition), and paste cloth. In the manufacturing process, the working time is prolonged and the cost of materials is increased. At the same time, when the blade is put into operation, the cloth layer will fall off during operation, resulting in loosening of the wire.

[0012] figure 2 It is a structural schematic diagram of the lightning protection device for the wind blade of the wind power generating set according to the present invention. The position of the lightning conductor 1 is moved to the aerodynamic surface close to the blade 2 through vacuum infusion, and it is fixed on the aer...

Abstract

The invention discloses a lightning protection device for blades of a wind generating set, which comprises a lightning protection conducting wire for connecting a vane with a tower body. The device is characterized in that the lightning protection conducting wire is poured into the pneumatic surface of the vane in a vacuum way. The conducting wire is moved near the pneumatic surface of the vane through vacuum pouring, and the conducting wire is fixed on the pneumatic surface of the vane through vacuum pouring, thereby ensuring that the conducting wire is not loosen, saving material and enhancing efficiency.

Description

technical field [0001] The invention relates to a lightning protection device for wind blades of a wind power generating set, belonging to the technical field of wind power generation. Background technique [0002] Wind energy is the renewable clean energy with the most mature technology and the most conditions for large-scale development. Wind power generation provides the basis for the harmonious development of man and nature. Due to the rapid development of modern science and technology, the single-unit capacity of wind turbines is increasing. In order to absorb more energy, the height of the hub and the diameter of the impeller increase, which also increases the risk of being struck by lightning. It is one of the most harmful disasters to the safe operation of wind turbines. The huge energy released by lightning can cause damage to wind turbine blades, generator insulation breakdown, and burnout of control components. The terrain in my country's coastal areas is compl...
