Storage battery and pantograph traced power supply system for urban rail vehicle

Abstract

The invention provides a storage battery and pantograph traced power supply system for an urban rail vehicle, comprising a monitoring module and a controlling module. The monitoring module is used for monitoring the state of the pantograph, the speed of the urban rail vehicle and the state of a high-speed circuit breaker. The controlling module is used for controlling the conversion of the urban rail vehicle from the high-pressure power supplying mode of the pantograph to the power supplying mode of the storage battery when the monitoring module monitors that the pantograph is in the falling state, the speed of the urban rail vehicle is zero, and the high-speed circuit breaker is in the switch-off state and is used for controlling the vehicle to switch from the high-pressure power supplying mode of the pantograph to the power supplying mode of the storage battery; when the monitoring module monitors the interruption of the high-pressure power supplying mode of the pantograph or the urban rail vehicle is in an emergency (enters an area without electricity) so that no other rescuing vehicle needs to be dispatched and the urban rail vehicle can run consecutively under the power supplying mode of the storage battery. Therefore, the rescuing tasks are reduced, the reusing vehicle occupies the main operating rail for a shorter time, and the operation efficiency of the urban rail vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of urban rail vehicles, in particular to a storage battery and pantograph traction power supply system for urban rail vehicles. Background technique [0002] At present, the traction system used for urban rail vehicles is mainly the current traction of the pantograph catenary or the third rail of the current collector; the power supply voltage is DC1500V or DC750V. Is the power supply voltage of the pantograph and current receiver the same? [0003] In the prior art, a pantograph or a current collector is installed on the urban rail vehicle. When the vehicle is running normally, the vehicle inputs high-voltage electricity to the vehicle through the pantograph or current collector, and the high-voltage electricity drives the vehicle to run. . However, when an emergency occurs in the vehicle, for example, entering a dead zone, the vehicle will not be able to operate due to the loss of power source. At this ...

Problems solved by technology

However, when the vehicle has an emergency situation, for example, entering a dead zone, the vehicle will not be able to operate due to the loss of power source

At this time, we can only wait for the rescue vehicle to come to the rescue, which will take up a lot of running time of the main line, and eventually cause the reduction of vehicle operation efficiency
