导电碳棒
  • 成本低


  • 无法解决高频电流趋肤效应

  • 与轴面局部接触

  • 浸油条件下寿命大幅缩短

  • 压力弹簧长期受热后弹力衰减,需定期更换

  • 高震动条件下,碳棒弹跳

VGR高导电纤维接地环

  • 结构多样,适用性广

  • 有效解决高频电流趋肤效应

  • 接触面充分

阻断

绝缘轴承

  • 可有效阻断轴两端循环电流
  • 高成本

  • 装配要求高

  • 只能转移问题,无法彻底解决系统的问题(例如:轴电压会从齿轮箱处释放)

扼制共模磁环
  • 可改善系统EMI表现

  • 需要较大安装空间

  • 装机成本高

  • 轴电压降低非常有限,无法消除轴承击穿放电风险
