6.2.6抑制滑环现在市场上很容易买到在几吉赫兹频率上具有优异性能的滑环,但使用滑环进行供电时,很容易引起电火花,从而产生电磁干扰,腐蚀滑环的接触区域,降低滑环的寿命。最好的解决办法是使用感性耦合方式替代滑环供电,即将变压器线圈分成两部分,一部分固定,另一部分旋转。还有一种方法是使用光学转动关节,但目前人们能够将激光能转换成电能的能力只有几瓦,如果需要对供(上接2011年第5期74页)
6.2.6 Suppression of slip rings Slip rings with excellent performance at several gigahertz frequencies are readily available on the market, however, when slip rings are used for power supply, sparks can easily occur, resulting in electromagnetic interference and corrosion of the slip ring contacts Area, reducing the life of the slip ring. The best solution is to use inductive coupling instead of slip ring power supply, the transformer coil is divided into two parts, one part of the fixed, the other part of the rotation. Another method is to use optical rotation of joints, but at present people have the ability to convert laser energy into electrical energy only a few watts, if you need to supply (on the next 5 of 2011 74)
