【摘要】 区别于传统的轮轨列车,高速磁浮列车在运行过程中其牵引变流器设备放置于轨道沿线的变电所中,且根据牵引要求不同进行不等距布置从而形成牵引供电分区;在每个牵引供电分区内,为减小损耗,牵引电机定子采用分段布置。基于上述特点,本文在对高速磁浮列车运行特性和列车牵引电机特性分析的基础上,提出一种高速磁浮列车牵引供电分区及定子段设计方法。通过设定列车顶层指标,结合高速磁浮列车的牵引特性,实现对高速磁浮列车牵引供电分区和定子段长度计算。以京沪线路为例,利用本文所提出的设计方法对供电分区及定子段长度进行计算,验证了设计方法的可行性,以期为高速磁浮列车未来应用提供设计依据。更多还原

【Abstract】 Different from the traditional wheel-rail train,the traction converter equipment of the high-speed maglev train is placed in the substation along the track during the operation,and the traction power supply division is formed by the unequal arrangement according to the different traction requirements.At the same time,in each traction power supply division,the traction motor stator is arranged in sections to reduce the loss.In view of the above features,this paper proposes a design method of traction power supply division and stator segment of the high-speed maglev train based on the analysis of the operation characteristics and traction motor characteristics of the high-speed maglev train.By setting the top level indicators of the train and combining the traction characteristics of the high-speed maglev train,the calculation of the traction power supply division and the stator segment length of the high-speed maglev train is realized.Taking the Beijing-Shanghai line as an example,the design method proposed in this paper is used to calculate the power supply division and stator length,which verifies the feasibility of the design method and provides the design basis for the future application of high-speed maglev train.更多还原
