目前,在化工矿山系统中,除极少数卷扬机采用可控硅串激调速或直流传动控制方式外,绝大多数仍采用异步电机转子回路串加电阻的方式起动与调速,且串加电阻的选择大多仍采用50～60年代的计算方法。锦屏磷矿主井卷扬属于后一种控制方式。为了节能与安全,我们对 At present, in the chemical mining system, with the exception of a handful of winches using SCR speed control or DC drive control, the vast majority still use asynchronous motor rotor circuit series plus resistance start and speed control, and series plus resistance Most of the options are still used 50 to 60 years of calculation. Jinping phosphate mine main shaft hoisting is the latter control. In order to save energy and safety, we are right
