内蒙古克什克腾旗黄岗铁锌矿混合井凿井施工中的提升机电动机型号为 JR1510-8,定子电压6 kV,功率475 kW,转子电压605 V,转子电流473 A,电动机重量4 530 kg。在施工中提升电动机转子引线短路,转子2根引线在绕组根部断裂,造成全面停产,生产工人在井下不能升井,严重威胁到人身安全。笔者在现场紧急制定了抢修方案,通过实 Inner Mongolia Keshiketengqi Huanggang Iron-Zinc Mine shaft sinking in the construction of hybrid motor model JR1510-8, the stator voltage of 6 kV, power 475 kW, the rotor voltage of 605 V, the rotor current of 473 A, the motor weight of 4 530 kg . During the construction, the lead of the motor rotor is short-circuited, and the two leads of the rotor are broken at the root of the winding, resulting in a total stoppage of production. The production workers can not raise the shaft in the well, which is a serious threat to personal safety. The author at the scene urgently developed a repair program, through the real
