耐用型滑环制作工艺常见问题及应对策略分析

Analysis of Common Problems and Countermeasures in Manufacturing Process of Durable Slip Rings

滑环主要为风力机组控制系统提供动力,并承担了控制器与传动控制系统之间的大数据与信息安全链连接。尽管滑环在风力机组总价值中所占有的份额很少,但滑环的总体性能、可靠性和使用寿命却直接影响着全机的性能与可靠性。因为第一个滑环的设计错误会导致后续的维修问题,滑环固件会出现更多错误。文章分析了多滑差所引起的高精度信号链的分离、传动优化问题以及安全间隔方案,并提出了中长期滑差保护方法,以最经济的方法改善了机组的稳定性,减少了机组停机时间,并减少了配件更新成本,提高了风电场的经济效益。

The slip ring mainly provides power for the wind turbine control system,and undertakes the big data and information security chain connection between the controller and the transmission control system.Although slip rings account for a small share of the total value of wind turbines,the overall performance,reliability and service life of slip rings directly affect the performance and reliability of the entire machine.Because the design error of the first slip ring can lead to subsequent maintenance problems,there will be more errors in the slip ring firmware.The separation of high-precision signal chain caused by multiple slips,the transmission optimization problem and the safety interval scheme are analyzed,and the medium and long-term slip protection method is proposed,which improves the stability of the unit in the most economical way and reduces the downtime of the unit,and reduce the replacement cost of accessories and increase the economic benefits of the wind farm.
