接触网张力补偿滑轮组传动效率测量研究

Study on the Transmission Efficiency of Catenary Tension Force Compensation Pulley Blocks

针对测量接触网张力补偿滑轮组传动效率时出现的问题进行分析,认为测量时滑轮传动效率、补偿滑轮组及测量系统的重力对测量结果影响很大,甚至会大于滑轮组摩擦力的影响。结合试验测量数据,提出对张力补偿滑轮组传动效率测量数据分析的新方法。

By analyzing the problems of measuring the transmission efficiency of catenary tension force compensation pulley blocks, the author considers that the transmission efficiency of the pulley block at the time of measuring, the compensation pulley blocks and the gravity of the measuring system would have larger influence on the measuring results than the friction of the pulley blocks. By combining with the experimental measurement data, the author gives new method for the measurement and analysis of tension force compensation pulley blocks.
