对煤矿大、中型电机(包括变压器)局部的突然事故,如果组织得好,技术指导有方,有些电机是可以在现场抢修好的。我矿综机二队的B·J·D—300采煤机系英国B·J·D公司的产品,电动机型号为F35。功率300kw;电压1100V;电流205A;cosφ0.85;η90%;频率50Hz;绝缘等级F。本电机转子结构设计不合理,有两次因转子轴向端部硅钢片断裂甩掉后,将定子端部上层绕组刮坏,造成(?)间和对地击穿。有
For coal mine large and medium-sized motor (including transformers) local sudden accident, if well organized, technical guidance, some motor is repaired in the field. The BJD-300 shearer of the Second Team of Mine Caving System is a product of British BD company, the motor type is F35. Power 300kw; Voltage 1100V; Current 205A; cosφ0.85; η90%; Frequency 50Hz; The motor rotor structure design is unreasonable, twice after the axial end of the rotor silicon steel sheet off after the fracture, the stator end of the upper winding scratch, resulting in (?) Between and on the ground breakdown. Have
