摘要
Abstract
A DVS evaluation scheme based on Rayleigh scattering is proposed to solve the problems of complex design and high cost of distributed vibration sensor system.Firstly,the strain distribution of cable fiber is analyzed theoretically and mechani-cally.Secondly,an experimental device is designed to evaluate the dynamic strain and shock capability of DVS monitoring pow-er cables.In the experimental stage,a power supply cable is analyzed by cyclic load and impact test.The cyclic load test results show that the strain frequency and phase of a single point on the sensing fiber are consistent with those in the deflection range of the hydraulic actuator.The impact test shows that the strain amplitude decreases exponentially after the initial impact.The experimental results are in accord with the practice,which further verifies that the proposed DVS monitoring scheme can realize the power strain curve drawing process.This scheme provides an important data base for power intelligent security and detec-tion.关键词
