在铁路客运高速化、货运重载化的同时,货运列车提速也已逐渐提到日程上来,机车的最高运行速度将会达到120 km/h.电力机车牵引传动制式将由直流传动变为交流传动,大功率交流机车将逐步取代直流机车.从大功率交流机车牵引性能、牵引质量适应性和制动性能等3方面,对大功率交流机车进行了介绍,并以大包线集包段为例,对大功率交流机车的应用进行了验证.
While the speed of railway passenger transport and freight transport are overloaded, the speed-raising of freight trains has gradually been put on the agenda, and the maximum running speed of the locomotives will reach 120 km / h. The traction drive system of electric locomotive will change from DC transmission to AC transmission, High-power AC locomotive will gradually replace DC locomotive.From the aspects of traction performance, traction quality adaptability and braking performance of high-power AC locomotive, the high-power AC locomotive is introduced, The application of high-power AC locomotive has been verified.
