   主井皮带原采用2台高压电机拖动，整套系统工作是由2台315kW/6kV高压异步电动机并联拖动。
     主井皮带是柳湾煤矿的中枢，一旦皮带机不能正常工作，将造成全矿停产，不但影响生产，造成巨大经济损失，而且会引起严重的社会影响。
     原有系统采用交流绕线式电机串电阻调速系统。该调速系统属于有级调速，调速的平滑性差；低速时机械特性较软，静差率较大；电阻上消耗的转差功率大，节能较差；起动过程和调速换挡过程中电流冲击大；中高速运行震动大，安全性较差。该调速系统在解决电机间同步，以及出力不均的问题时能力明显不足。机械磨损和老化问题日趋严重，性能逐年降低，故障率增加，设备维修难度大;整个系统效率低，调速范围有限，稳定性差。

3. 变频调速新系统装置概述

       主井皮带采用3台高压电机拖动，整套系统工作是由3台710kW/6kV高压异步电动机并联拖动。其中两台电机同轴拖动同一滚筒，另一电机单独驱动另一滚筒，皮带运输机传动系统如图1所示。

       该系统不仅要求3台速度同步，而且3台负荷分配要均衡一致，如图2所示。

       综合以上因素，甲方考虑采用高压变频调速装置驱动皮带系统，但是，由于目前国内外高压变频器的应用领域主要在风机水泵等变转矩应用方面，很少有恒转矩重载设备驱动的实例，而重载多单元同步控制的成功应用更是几乎没有，新柳煤矿非常慎重，经过综合考查了国内外多家变频厂商，同各方面专家进行了多次的研讨，最终确认了日本明电舍的VT710高压变频器驱动装置的系统方案。图２为皮带运输机高压变频器驱动系统图。
