The horizontal axis wind turbine has a collector ring, but the vertical axis does not.
Because the wiring of the horizontal axis wind turbine main engine is horizontal, and because there is a rotary body that must be aligned with the wind speed, The machine head part is rotating.
The function of the collector ring is to rotate 360 degrees without any obstacles and lead the wires vertically downward.
If no collector ring is used, the three wires of the main machine are in It is easy to get entangled and twisted when the main unit rotates.
Gold and silver. According to relevant public information inquiries, the precious metals commonly used in wind power slip rings include silver and gold. This is because silver has good electrical and thermal conductivity, can effectively transmit electrical signals and energy, and is relatively cheap. Gold, on the other hand, is a higher-quality conductive material that can ensure the stability and reliability of transmitting electrical signals and energy, but the price is relatively high.
