相邻高铁间联络线供电设置电分段或电分相方案研究

Study on Scheme for Setting of Electrical Sectioning or Phase Separation for Power Supply of Connecting Tracks between Adjacent High-speed Railways

随着我国高速铁路的不断发展,各条高铁线路之间由于互联互通的需要设置的联络线日益增多,联络线供电的安全性、可靠性直接影响着运输组织的安全。本文通过对相邻高铁线路由不同牵引变电所供电和由同一牵引变电所供电两种工况下联络线上设置电分段或电分相装置进行分析研究,尤其针对第二种工况,结合具体的项目案例研究分析设置电分段和电分相的优缺点,最终给出两种工况下联络线设置电分段或电分相的建议。

With the continuous development of high-speed railways in China,more and more connection tracks are set between high-speed railway lines due to the need of interconnection.The safety and reliability of power supply of connection tracks directly affect the safety of transportation organization.The paper analyzes and studies the advantages and disadvantages of setting electric sectioning or electric phase separation devices on connection tracks under two working conditions of adjacent high-speed railway lines being powered by different traction substations and by the same traction substation,especially for the second working condition,combined with specific project cases,and finally gives suggestions on setting electric sectioning or electric phase separation devices on connection tracks under two working conditions.
