| Summary: | In order to solve the problem that the reconnection of CRH6F-A/CRH6A-A short intercity EMU can not meet the requirements of the length of neutral section of domestic lines, the reconnection control method of short intercity EMU was studied,and the reconnection control strategy of single pantograph passing neutral section was put forward. A kind of valve plate used for quick putting down pantograph was designed, and the performance of the lifting and dropping pantograph under different speed grades was tested through experiments, which included the signal response speed, the time and distance of lifting and dropping pantograph, and the arcing performance of the pantograph. The test results show that the single pantograph passing neutral section control technology is feasible and the arc-ignition rate of pantograph-catenary system is low when the pantograph-catenary system is lifting and dropping dynamically, and the impact on the pantograph-catenary is small. The research overcame the bottleneck of the length limitation of the neutral section in the multiple operation of the short marshalling EMU, realized the flexible operation of the short marshalling EMU,and effectively relieved the passenger pressure in the peak period of passenger flow. |
