摘　　要：针对泽州天安朝阳煤业DTL100/50/132皮带运输机出现的不能实现功率平衡、机械损伤大等问题进行了主-从低压变频调速系统项目的研究改造.采用主-从低压变频调速系统替代以往的液力耦合器驱动系统,解决了皮带运输机多个驱动电机转矩不平衡的问题,同时实现了运行速度随负载量的变化而实时变化,节能降耗效果显著.The main-slave low-voltage variable-frequency speed regulation system project is reformed in view of the problems of failure to achieve power balance and large mechanical damage in DTL100/50/132 belt conveyer in cheonan chaoyang coal industry. The main-slave low-voltage variable-frequency speed regulation system is used instead of the previous hydraulic coupler drive system, which solves the problem of torque imbalance of multiple driving motors of belt conveyer, and realizes the real-time change of running speed with the change of load quantity,and the effect of saving energy and reducing consumption is remarkable.
