开滦钱家营矿主副井提升系统全套设备均自西德引进,其机械部分是德马克公司制造,电气及控制部分由西门子公司配套。主井为φ4.5×4落地式多绳绞车,副井为φ3×4落地式多绳绞车两台。绞车电动机均是低速直流电动机直联。主井为2500kW两台,副井两台均为1150kW。直流电动机的电枢由两组串联的可控硅变流器供电,采用顺序控制;电动机的励磁绕组由两组反并联可控硅变流器供电,采用逻辑无环流控制。
Kailuan Qianjiaying mine main and auxiliary shaft lifting system full set of equipment are imported from West Germany, the mechanical part is made by Demark Company, the electrical and control part of the supporting by the Siemens company. The main shaft is φ4.5 × 4 floor type multi-rope winch, auxiliary shaft is φ3 × 4 floor type multi-rope winch two. Winch motors are direct low-speed DC motor. The main shaft is 2500kW two, auxiliary shaft two are 1150kW. The armature of the DC motor is powered by two series-connected thyristor converters and is controlled in sequence. The field winding of the motor is powered by two sets of anti-parallel thyristor converters and adopts a logic-free recirculation control.
