A method for controlling a main circuit of a traction system is provided. The method includes: under a braking condition, controlling a protection module to be turned off; controlling the protection module to be turned on and monitoring a first current detected by a first current sensor in a case that a rail vehicle runs on a charged third rail; and controlling the protection module to be turned off and monitoring whether the rail vehicle runs on a charged third rail in a case that the first current is less than a first preset current.

Main circuit of traction system and control method therefor and rail vehicle

A braking force distribution method and system for multiple marshalling train compartments are provided. The method includes: determining a current train compartment of multiple target marshalling train compartments, calculating current axel loads of axels of the current train compartment, and distributing braking forces for the axels of the current train compartment in a positive correlation manner based on the current axel loads of the axels. The braking forces of the axels are distributed by using an axel load compensation technology. A braking force generated by an axle with a small axle load is reduced according to a load-decreasing amount of the axle load, while a braking force generated by an axle with a great axle load is increased according to a load-increasing amount of the axle load, so that the braking forces generated by the axles match the axle loads.
