摘　　要：风力发电机组偏航工况下,通常采用扭缆系统实现电能传输。传统的扭缆系统结构复杂、设计难度大,存在电缆下滑、磨损、过温等问题,本文提出一种新型扭缆系统,采用双重承重、不接触、有间距敷设等方案解决上述问题。此外,随着机组容量的增大,扭缆系统中电缆根数会超出极限,因此本文开发了无电缆扭缆的偏航集电环系统来实现偏航工况下的电能传输。样机验证结果表明,本文开发的偏航集电环系统可彻底解决扭缆系统中电缆现存的问题。Under the yaw condition of wind turbines,a twisted cable system is usually used to achieve power transmission.The trational twisted cable system is complex and difficult to design,and there are problems such as cable slip,wear and overtemperature.A new twisted cable system is proposed in this paper,which adopts which adopts dual load-bearing,non-contact and spacing laying schemes,to address these problems.At the same time,the number of cables is prone to exceed the limit as the capacity of the unit increases.Thus,the yaw collector ring system without twisted cable is developed to achieve power transmission.The prototype verification results show that the developed system can completely solve the existing problems of twisted cables.
