Traction control system for high-speed passenger train

Abstract

The invention relates to a control system of a downhole human transport device, in particular to a high-speed manned train traction control system which comprises an electrical main system, a braking control system and a braking failure alarm device. The electrical main system comprises a pantograph type current collector, a circuit breaker, a braking resistor, an AC asynchronous traction electric motor, an inverter, an electric reactor and a driver controller. The braking control system comprises exhaust braking systems and brake switches SA, wherein the exhaust braking systems and the brake switches SA are installed on a manned vehicle. The braking failure alarm device comprises pressure relays and failure indicator lamps, wherein the pressure relays and the failure indicator lamps are additionally arranged on brake cylinder pipelines in all the exhaust braking systems. After the high-speed manned train traction control system is used, it takes people about three hours to enter and leave a well mouth, and working time is saved by two hours. Meanwhile, blackout failures caused when a disconnected pantograph type current collector is grounded are eliminated, a train runs more safely and reliably, the impact caused by the manned vehicle behind on a DC locomotive is eliminated, and riding comfort is improved.

Description

technical field [0001] The invention relates to a control system for underground people transport equipment, in particular to a traction control system for a high-speed passenger train. Background technique [0002] With the mining of mine resources, the mine tunnels are getting deeper and deeper, and the distance between the mining coal surface and the wellhead is as long as ten to twenty kilometers, and it may be deeper in the future. The time it takes for workers to reach the production face from the wellhead is correspondingly increased. Due to the limitation of the underground tunnel environment, the speed of industrial and mining vehicles is not very fast. According to years of operating experience, the average speed of industrial and mining vehicles is 10.8Km / h, and the fastest speed is 17-18Km / h. In order to improve production efficiency and avoid wasting effective working time on the road, it is necessary to increase the speed of transport vehicles for transporting...

AI Technical Summary

Problems solved by technology

The passenger car has no braking system and only relies on the traction locomotive to brake. The braking distance is long. During emergency braking, the passenger car hits the vehicle in front one after another, which has a great impact on the occupants, making the ride uncomfortable, and there is a big safety hazard

The pantograph used by the DC motor locomotive is a double-bow head. After connecting the two bow heads through a cable, the circuit breaker is connected. The pantograph is a double-bow head. Short circuit, resulting in loss of power to the overhead network
