| 摘 要： | 为解决难以方便、有效地在线监测交、直流输电线路电晕损耗的问题，提出了适用于交、直流输电线路电晕损耗在线监测的金属化膜法。该方法在输电导线表面包裹一层薄的、一定长度的金属化膜，包裹薄膜朝外的一面是导电金属镀层，靠近输电导线的一面是绝缘材料层。在金属镀层和输电分裂导线间并联采样电阻。采样电阻将流过的泄漏电流转换为电压信号，...

| Abstract: | The metalized membrane method,in which transmission line was coated by metalized membrane where the insulated layer was next to transmission line and mental layer was outwards,was applied to monitor the corona losses on AC/DC transmission lines online.The sampling resistance between transmission line and membrane could convert leakage current to voltage signal which would be sent to a computer by wireless telecommunications way or optical fiber transmission way.The voltage of transmission line would also be... |
