通过对引进技术的消化、实验室模拟调试、现场静态和动态工业试验、现场可靠性运行试验等四个阶段,长沙矿山研究院和南芬露天矿合作研制成功了一种用于120C电动轮汽车的KS——100型励磁系统,并已通过了鉴定。工业试验表明:该系统的静态和动态性能基本达到了美国同类产品的标准,恒功精度达到±18～22马力(美国标准为±32马力),电压限制、电流限制、车速限制均稳定可靠。与原用装置比较,在相同坡度和荷载的情况下,重车 Through the four stages of digestion of imported technology, laboratory simulation and commissioning, on-site static and dynamic industrial tests, on-site reliability operation test and so on, Changsha Mining Research Institute and Nanfen Open-pit Mine have successfully developed a joint project for 120C electric wheel car KS-100 excitation system has passed the appraisal. Industrial tests show that the static and dynamic performance of this system has basically reached the standard of similar products in the United States. The constant power accuracy is ± 18 to 22 horsepower (US standard is ± 32 hp). The voltage limit, current limit and speed limit are both stable and reliable. Compared with the original device, in the case of the same slope and load, heavy vehicles
