通过对造成换流站光纤局部放电的原因进行分析，采用加强光纤等电位和接地处理，并在光纤表皮聚四氟乙烯材料中加入炭黑，研究解决换流站阀厅光纤局部放电问题的方法。结果表明：经过加强光纤等电位和接地处理，光纤表皮材料聚四氟乙烯经过炭黑改性后，光纤表皮材料和光纤材料的介电常数和电阻率相匹配，自由电荷在光纤表皮材料上的累积减少，释放速度加快，从而有效消除了光纤局部放电现象。

The cause of optical fiber partial discharge in converter station was analyzed. Through enhanc-ing the equipotential and grounding treatment of optical fiber, and adding black carbon into fiber PTFE surface material, we studied the solutions of optical fiber partial discharge problems of valve hall in converter station. The results show that after enhancing the equipotential and grounding treatment of fiber and adding black carbon into the fiber PTFE surface material, the permittivity and resistivity between the optical fiber and surface material is more matching, the accumulation of free charge on the suface material decreases, and the release of free charge speeds up, which can eliminate the fiber partial discharge phenomena.
