| Abstract: | Contact rail system is an important component of third rail metro traction power supply system.The correct installation of contact rail is the premise of safe vehicle electrification.For the lower contact rail installation on the longer sleeper,mathematical relationship between installation position of contact rail and rail cant is derived.The calculation method of allowable rail cant displacement when contact rail is correctly installed is given,and the allowable rail cant range under two common installation parameters range is listed.In the end,remedial suggestions are given for the installation failure situation where the rail cant is beyond the allowable installation range of the contact rail. |
