摘要
矿井进风大巷采用直流架线电机车作为辅助运输设备,其供电系统存在直流杂散电流问题。首先阐述了直流杂散电流成因,其次列举了直流杂散电流对煤矿安全生产的危害,最后结合杂散电流的成因和实际情况,从不同角度给出了杂散电流防治工作的思路。
The large mine air intake roadway uses DC overhead electric locomotives as auxiliary transportation equipment,and its power supply system has DC stray current problems.First,the cause of DC stray current is explained.Secondly,it lists the hazards of DC stray current to coal mine safety production.Finally,combining the causes of stray current and the actual situation,the ideas of stray current prevention and control are given from different angles.
