摘要:

研究了一种基于参考信号的无源互调故障定位技术.该技术比传统无源互调测量技术多了一个参考信道,提供参考信号,解调互调信号相位响应,同时引入校准技术,在测量端口构建参考平面,通过频时转换得到相对于参考平面的时域响应,有效地进行故障排查.在此基础上,仿真故障定位实验验证了理论的正确性,设计并制造相位参考板,测试结果与实际值比较表明:电缆上两个故障位置实际值与测量值之差的绝对值均≤1m,实际相对误差分别约为5.1%、2.4%,证明了这种方法的正确性和可行性.该技术将克服传统故障定位的不足,更适应于恶劣的地域环境.

Abstract:

Passive inter-modulation fault location technology based on the reference signal is researched.The technology has one more reference channel than the traditional passive inter-modulation measurement techniques,to provide a reference signal,to demodulate phase response of the inter-modulation signal,while introducing calibration technology in the measurement port to build the reference plane,Obtained Time domain response relative to the reference plane By the time-frequency conversion and effective troubleshooting.Based on this,the fault location test is simulated to prove the validity of theory,and the phase reference board is designed and fabricated,the experimental results and the actual value showed that:Absolute value of the difference between the actual value and the measured value of two fault location on the cables are ≤ 1m,the actual relative error of approximately 5.1%,2.4%,proves the correctness and feasibility of this approach.The technology will overcome the shortcomings of traditional fault location,adapts to the nasty geographical environment.

Key words: passive inter-modulation, fault location, reference signal, calibration technology, reference plane
