煤矿井下长轨焊接实践

Discussion on Underground Long-Rail Welding Principle

煤矿井下长轨焊接新结构,解决了行驶架线电机车的铁道的接头连接导线断面不够和连接不良而加大回馈电阻的问题,从而减少了杂散电流,消除了不安全的隐患,提高了机车运输效率。在集团公司推广,已经取得了很好的技术经济效果。

The paper introduces the new principle of underground long--rail welding, which can not only reduce the stray current and power consumption by solving the problems of the traverse joint connection in the connector of rail of running trolley locomotive, but also eliminate the unsafe hidden trouble and improve the transport efficiency of locomotives.
