目前我国斜井单绳绞车及井下上下山单绳绞车(或双绳绞车重车下放)是非常多的,且由于地质情况,投资少,出煤快及出煤多,我国将会有更多斜井出现。这些绞车大多为卷线型感应电动机所拖动,根据理论之分析及我们实习中在阜新、抚顺及鸡西对斜井绞车之测定,以及峰峰矿务局利用单钩绞车下坡发电试验经过之总结,肯定大多数斜井矿车下放是可以利用列车自重拖动电动机转而为发电机运转方式,达到发电反馈的。这样不但可以发电,节约用电,而且可以等速下降,因之对安全具有特别重要的意义。矿车下放,现场均是以电动机起动方式起动,消耗电能颇大。倘每列车矿车数目足够多,而坡度亦较大,则起动时,矿车自溜带动整个绞车运动系统,待转速达同步转速左右, At present, there are a lot of single-winch winches and single-winch winches (or double-winch winches) in our country, and there will be more in our country due to the geological conditions, less investment, quick coal output and more coal output. Inclined shaft appears. Most of these winches are driven by winding induction motors. According to the theoretical analysis and the determination of inclined winches in Fuxin, Fushun and Jixi in our internship, and the Fengfeng Mine Bureau’s use of a single hook winch downhill power generation test To sum up, surely most of the shaft mine car decentralization is the use of train weight drag the motor instead of the generator mode of operation, to generate electricity feedback. This not only can generate electricity, save electricity, but also can be decayed, so the safety of particular importance. Mine car decentralized, the scene is based on the motor starting start, consume a lot of power. If the number of trains per train is large enough and the slope is also large, when starting, the car will drive the entire winch motion system by its own speed, until the speed reaches about synchronous speed,
