本文介绍了逆变器控制感应电动机的交流传动机车、动车在防空转打滑等方面的技术。给出了粘着系数与打滑速度之间的关系,阐述了粘着系数与滑动摩擦系数在滑差速度为零点上是不相等的,即有一些落差的观点。同时,对列车速度,空转打滑的检测方法以及采用逆变器控制的普通线路电车、新干线电车和电力机车关于粘着恢复控制等方面作了综合评述,介绍了德国等国使用逆变器控制机车车辆的经验。
This article describes the inverter control of induction motor AC drive locomotive, skidding and other aspects of the anti-slip technology. The relationship between the coefficient of adhesion and the speed of slip is given, and the relationship between the coefficient of adhesion and the coefficient of sliding friction is not equal at the slip speed of zero, that is, there is some drop point. At the same time, a comprehensive review was made on the detection methods of train speed and idling slippage, as well as the common line trams, inverter trains and electric locomotives that are controlled by inverters. In addition, the use of inverter-controlled locomotives in Germany and other countries is introduced Vehicle experience.
