高压真空接触器在高速磁浮交通中的应用

Application of High Voltage Vacuum Contactor in High Speed Maglev Transportation

高速磁浮交通作为一种新型的交通运输方式，具有安全、高速、舒适和环保的特点。其牵引系统是磁浮系统的一个重要的子系统，牵引系统为列车提供运行中所需要的牵引力和制动力，而高压真空接触器又是牵引系统中重要的设备。文章基于上海磁浮线，对高速磁浮交通的牵引系统总体配置情况进行了介绍，描述了重要设备之一的高压真空接触器在牵引系统中的功能、设备的主要数据和使用情况。

As a new transportation way, High speed maglev Transportation is characterized with safety, high speed,comfort and good environmental protection. Propulsion system is an important subsystem of Maglev. The main function is to provide driving and braking force for train operation. High voltage contactor is one of key equipment in the propulsion system. In this paper the configuration of propulsion system is introduced. Based on the Shanghai Transrapid Line, the function, technical data and usage of high voltage vacuum contactor are described.
