Analysis induced voltage of the three fracture insulated overlap anchor section

摘要 通过分析三断口锚段关节式电分相技术特征,研究绝缘锚段关节中接触网空间结构布置,建立了动车组自动过分相暂态模型,经与实际测量结果对比分析,证明了车网耦合感应电压计算方法的准确性．研究结果表明:列车行进状态影响空间分布电容,使得三断口分相两中性区具有明显电势差．
Abstract： Through the analysis of the three fracture anchor section articulated phase insulator technology characteristics and work spatial structure arrangement, the EMU's automatic splitting phase transient model is analysed and established. Compared with the actual measurement results, the accuracy of confirmed EMU and contact wire coupling induction voltage calculation method has been proved.The research results show that the train moving states influence the distribution of capacitance, making the three fracture phase two neutral zones have obvious potential difference.
