The traditional power transmission mode can not meet the requirements of some special application occasions. For example, in a wind power generation system, when a fan is driven to rotate by wind power, the blade of the fan often needs to be adjusted in posture, and energy required for driving the blade to rotate is often transmitted through a conductive slip ring. However, there are a number of disadvantages with conductive slip rings: firstly, the conducting ring is worn, if the content of the lubricant is high, the wearing capacity is small, but the conductivity is poor; on the contrary, the lubricant content is small, the conductivity is good, but the abrasion loss is increased. Secondly, the contact part of the slip ring and the electric brush generates heat greatly, and the heat dissipation of the conductive ring is difficult to realize through conduction because the conductive ring channel and the channel are required to be insulated, and the insulating material usually has poor heat conductivity.
