电力电缆及附件故障的行波反射检测方法

Fault Detection Method of Cable and Accessory Based on Traveling Wave Reflection Method

根据行波反射法原理提出了恶劣环境中的电缆及附件故障检测的新方法,并进行了电缆接头故障和电缆接头绝缘老化的模拟实验,验证了该方法的有效性和可靠性,证明了其工程应用上的可行性和创新性,使煤矿、水利等行业在生产运行中有效避免电缆事故带来的损害,提高了生产效率。

According to the principle of pulse reflection, a new method for fault detection of cable and accessory used in harsh environment is presented in this paper. The failure of cable joints and the insulation aging of cable joints verified the validity and feasibility of the method. The damage caused by the electric cable accident in the operation of the coal mine, water conservancy and other industries can effectively be avoided..
