针对井下电机车易损坏维修难度大的问题:通过这5年来在维修多次故障现场总结了些改掉原设计的缺陷,在这5年维修中总了好的方案并重新改进电机车控制系统及直流接触器的结构,达到设备部件少损坏防水防尘性能好易维修维护及生产运输效率高能有好的电器制动安全的目的。通过CJY7/6G架线式工矿电机车矿井下机车运输电器控制系统机电基础松动故障的诊断实例,说明了更急故障特征判断设备松动公章有效性。
For underground electric locomotive easy to damage the maintenance of a big problem: Through these five years in the maintenance of several fault scene summarizes some of the original design to get rid of the defects in the five-year maintenance of a total solution and improve the electric car control system And DC contactor structure to achieve less damage to equipment components Water and dust proof and easy to maintain and maintain the high efficiency of production and transportation There is a good electrical braking safety purposes. By CJY7 / 6G overhead mining locomotive electrical locomotive control system electrical and mechanical foundation loose fault diagnosis example shows the more urgent fault feature to judge the validity of loose seal.
