一种输电线路接地闪络故障定位系统
摘要：
一种输电线路接地闪络故障定位系统，包括检测装置、数据处理装置和显示器。检测装置用于产生脉冲激光信号，并将脉冲激光信号传输至OPGW光纤，以及在向OPGW光纤传输脉冲激光信号之后，检测获得OPGW光纤的后向瑞利散射信号的偏振态；数据处理装置连接于检测装置，用于接收检测装置发送至后向瑞利散射信号的偏振态，并基于后向瑞利散射信号的偏振态确定输电线路接地闪络故障位置；显示器连接于数据处理装置，用于对后向瑞利散射信号特性波形进行显示，并对输电线路接地闪络故障位置进行提示。与现有技术相比，本实用新型实现了单端对输电线路故障位置的测量，具有结构简单、抗干扰能力强、可靠性高、定位准确、适用范围广等优点。
摘要（英）：

The utility model provides a transmission line ground connection flashover fault positioning system, includes detection device, data processing device and display. Detection device is used for producing the pulsed laser signal to with pulsed laser signal transmission to OPGW optic fibre, and after to the OPGW optical fiber transmission pulsed laser signal, detect the back polarization state to the rayleigh scattering signal that obtains OPGW optic fibre, data processing device connects in detection device for receive detection device and send to the polarization state of back to the rayleigh scattering signal, and confirm transmission line ground connection flashover fault position based on the back to the polarization state of rayleigh scattering signal, the display is connected in data processing device for show to rayleigh scattering signal characteristic wave form the back, and to transmission line ground connection flashover fault position indicateing. Compared with the prior art, the utility model discloses a single -ended measurement to transmission line fault location has advantages such as simple structure, the interference killing feature is strong, the reliability is high, the location is accurate, application scope is wide.
