三元煤业公司南寨矿于20世纪80年代末设计,90年代初投产,主立井为双箕斗提升系统,原设计年提升量60万t。主机为2JK-3.5/15.5型单绳缠绕式提升机,设计额定速度6.98m/s,提升高度376.8m;YR1000/10-1430型电动机(1000kW),定子118A/6kV,转子536A/1166V,转速690r/min。原设计为继电器控制系统,90年代末改造成三菱产FX2单PLC控制,电动机转子外串金属电阻调速方式,并带低频制动。
Sanyuan Coal Company Nanzhai Mine was designed in the late 1980s and put into operation in the early 1990s. The main shaft is a double-skip upgrade system with an annual increase of 600,000 tons. The main machine is 2JK-3.5 / 15.5 single-rope winding hoist with designed rated speed of 6.98m / s and lifting height of 376.8m; YR1000 / 10-1430 motor (1000kW), stator 118A / 6kV, rotor 536A / 1166V, 690r / min. The original design for the relay control system, the late 90s transformed into Mitsubishi FX2 single PLC control, motor rotor outside the metal resistor speed control mode, and with low-frequency braking.
