風力発電装置
Document Type and Number:
Japanese Patent JP7252740
Kind Code:
B2
Abstract:
To transmit power, generated by wind force, between a rotation part and a body part in a non-contact manner simultaneously with the power generation, to use a part of the power generated by the wind force in the rotation part which rotates with a wing.SOLUTION: Each coil C11, C12, C13 configuring a main coil 31 of a generator and each primary coil C21, C22, C23, C31, C32, C33 included in a non-contact transmission unit 50 are arranged in the body part. Each secondary coil C41, C42, C43, C51, C52, C53, included in the non-contact transmission unit 50, a three-phase diode-bridge rectifier circuit 60 and a wing angle change part 13 are arranged in the rotation part. The non-contact transmission unit 50 transmits a part of AC power, which is output from the main coil 31, from the body part to the rotation part in a non-contact manner. The three-phase diode-bridge rectifier circuit 60 rectifies to a DC voltage a three-phase AC voltage which is output through three output lines of the secondary coil, included in the non-contact transmission unit 50, to supply the DC voltage to the wing angle change part 13.SELECTED DRAWING: Figure 3
