Intelligent contact line traction power supply system for bottom-mounted pantograph of bed-free high-speed railway multiple unit train
The invention discloses an intelligent contact line traction power supply system for bottom-mounted pantographs of a bed-free high-speed railway multiple unit train, wherein an intelligent contact line is located in the middle of a long rail groove, and the lower end of the high-speed rail motor train unit is provided with a plurality of flexible bottom-mounted pantographs which are in sliding contact with a rigid intelligent contact line, so that the intelligent contact line can avoid accidents, such as vibration, off-line and pantograph falling, caused by a strong wind; intelligent contact lines in a running interval of a high-speed railway multiple unit train are electrified, and intelligent contact lines in a large range outside the running interval are not electrified, so that electric shock accidents of people and livestock are avoided; a bed-free track eliminates the need for a ballasted trackbed and a ballastless trackbed, so that the multiple left and right square rubber pads enable the track noise to be smaller; a long track groove is formed in the natural space between the multiple left half pillows and the multiple right half pillows, and a plurality of water outlets are formed in a natural space between the multiple left half pillows and the multiple right half pillows, so that the problem of water accumulation in the long track groove is solved; a distributed traction power supply system enables a plurality of converters, the bottom pantographs, a variable frequency motor and a variable frequency controller to be low in power and small in size with improved reliability.
一种无床高铁动车组底置受电弓智能接触线牵引供电系统，智能接触线位于长轨道槽的中部，高铁动车组的下端设置多个柔性的底置受电弓与刚性的智能接触线滑动接触，智能接触线避免了大风造成的振动、离线、脱弓等事故，高铁动车组行驶区间内的智能接触线带电，行驶区间外大范围的智能接触线不带电，避免了人畜触电事故，无床轨道省去了有砟轨道床和无砟轨道床，多个左、右方形橡胶垫使轨道噪音更小，多个左半枕和多个右半枕之间的自然空间形成长轨道槽，多个左半枕和多个右半枕前后之间的自然空间形成多个排水口，解决长轨道槽的积水问题，分散式的牵引供电系统使多个变流器、底置受电弓、变频电机和变频控制器的功率小、体积小、可靠性提高。
