摘要
利用相位敏感光时域反射(phase-sensitive optical time-domain reflectometer,Φ-OTDR)技术对导线进行舞动状态识别和实时监测.首先通过预绞丝将光纤复合相线(optical phase conductor,OPPC)安装在室内舞动试验机上,然后由激振器对OPPC施加不同的激振频率,最后分析不同激振频率下Φ-OTDR系统测量信号的特征.当激振频率不同时,Φ-OTDR系统测量信号具有不同的频率特征.
The phase-sensitive optical time-domain reflectometer(Φ-OTDR)is proposed to monitor the galloping of the optical phase conductor(OPPC).Optical fiber cables embedded inside OPPC is used as sensing elements.As the exciter of the galloping machine applies different excitation frequencies on the OPPC,the measurement signals ofΦ-OTDR system are analyzed to figure out galloping characteristics.For different excitation frequencies,theΦ-OTDR system measurement signals have corresponding frequency characteristics.
