摘要
电力线路中的电压或电流波遇到波阻抗发生突变,将产生折射和反射。利用这一原理可以诊断线路是否存在短路或接地故障。依据此原理并考虑铁路电力线路的特点,研究开发的新型电力线路故障自动处理装置,经实际运行考核,表明该方法实用可行。
When the surge impedance of the power line suddenly changes, the travelling voltage or current wave will produce refraction and reflection. The shortcircuit or ground fault in the power line may be diagnosed on the travelling wave principle. Considering the characteristics of the railway power line, a new type of automatic equipment for dealing with faults in the power line is studied on the travelling wave principle. Actual operation results show that the new automatic equipment is effective.
