In electric rail power supply systems, electric trains use pantograph and collector shoes to make contact with power lines, bringing electricity into the main transformer of the train and providing energy for the train. However, because of the swaying of the train at high speeds, contact friction and movement of the pantograph, collector shoes, and power lines; climate; terrain; and surface unevenness in the materials cause separation among the power line, the pantograph, and the collector shoes to occur and produce electric arcs. This study proposes the use of magnetic components to improve the separation of the pantograph and collector shoes from power lines (reducing the contact loss rates). This study also constructs a model for experiments for the contact loss rates of the pantograph and collector shoes from power lines to analyze the frequencies of electric arc occurrences. Experimental results showed that using magnetic components can effectively reduce contact loss rates, the occurrence of electric arcs, and surface wear caused by contact of the pantograph and collector shoes with power lines, thus reducing investment costs and increasing the quality of the power transmission of electric trains.
