交流接触网导线带电磨耗检测仪

针对铁路交流接触网导线传输电压27.5 kV,导线磨耗面为空间非平行(对大地)任意平面的特点,利用光纤隔离高压、传输测量信号,光栅式远端自适应自动机械测头实现离地高7 m左右的交流接触网导线磨耗带电检测的方法以及基于此方法的系统设计与校正,实现了带电高压导线磨耗的测量,实测表明该方法x及系统完全满足接触网导线磨耗检测的需要,对其他高压带电体几何量检测也有借鉴意义。

Online wine wearing detection device for AC contact network

For the transmission pressure 27.5 kV of the railroad AC contact network,and the non-parallel(on earth) arbitrary plane for the wire wearing surface,the optic fiber was used to isolate the high voltage and to transmit the measurement signal.A remote grating-type adaptive automatic machinery transducer was used to detect the AC contact network wire wearing surface with about seven meters from the ground.Based on this method,a system was designed and calibrated,achieving measurement of wire rubbing with high-...
