1990年6月在大秦线西段,成功地进行了韶山_3型电力机车双机重联牵引10000t C_(63)货车编组的单元列车运行试验。在最高限速为60km/h条件下,列车平均速度达到49.2km/h。试验结果表明:4‰限坡起动最大电流1234 A、最大挽钩力766kN;只使用了机车牵引能力的85％;紧急制动最大车钩力为-1200kN;长大下坡循环调速制动中,最长抱闸时间为234s,最低尾车副风缸压力大于0.54MPa;在12‰下坡上紧急制动后,列车缓解增速到60km/h时,空气制动系统仍有坡道调速循环制动的能力。试验证明了韶山_3机车双机重联牵引10000t C_(63)货车编组的单元列车是可行的。
In June 1990, in the western section of Daqin Line, the unit train operation test of the 10,000t C_ (63) truck with double reconnection of Shaoshan _3 electric locomotive was successfully carried out. The maximum speed of 60km / h conditions, the average train speed 49.2km / h. The test results show that: the maximum current of 4 ‰ limit start-up is 1234 A, the maximum pull-hook force is 766 kN; only 85% of the locomotive traction capacity is used; the maximum hook-up force of emergency braking is -1200 kN; , The longest brake time is 234s and the pressure of the tailmost auxiliary air cylinder is more than 0.54MPa. After the emergency braking on the 12 ‰ downslope, when the train slipping to 60km / h, the air braking system still has a ramp Quick cycle braking ability. The test proves that it is feasible to unit train the 10000t C_ (63) truck with the double-reconnection of Shaoshan _3 locomotive.
