摘　　要：针对神朔铁路的供电分相区多数处于长大坡道,电力机车传统过分相方式存在速度损失大和通过分相区时间过长等问题,电子开关过分相作为一种新型的带电过分相技术,首次在神朔铁路得到了应用。为适应电子开关快速换相,神华号电力机车的控制方式进行了相应的优化,在重载试验中,列车牵引、制动、惰行等工况均能实现带电、快速无故障通过电分相区。试验结果表明,神华号电力机车能适应基于电子开关的带电自动过分相的方式,速度几乎无损失,提高了重载铁路的运输能力。In view of the fact that most of the power supply phase separation sections of Shenshuo railway are on long ramps,the traditional way of passing phase for electric locomotives had the problems of large speed loss and long passing time.As a new technology of passing phase with electricity,the electronic switch passing phase had been applied in Shenshuo railway for the first time.In order to adapt to the rapid commutation of electronic switches,the control mode of Shenhua electric locomotive had been optimized accordingly.In the heavy-haul test,the working conditions of traction,braking and inertia of the train could realized fast and fault-free through the phase separation zone without power off.The test results showed that Shenhua electric locomotive could adapt to the way of automatic phase passing based on electronic switch with almost no loss of speed and improved the transportation capacity of heavy haul railway.
