Embodiment Construction

[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] see figure 1 , which is a schematic diagram of Embodiment 1 of the urban rail vehicle traction power supply system provided by the present invention.

[0034] The urban rail vehicle traction power supply system provided in this embodiment includes: a monitoring module 100 and a control module 200;

[0035] The monitoring module 100 is used to monitor the state of the current collector of the vehicle, the train speed and the state of the high speed circuit breaker (HSCB, High Speed ​​Circuit Breaker);

[0036] The control module 200, when the monitoring module 100 detects that the current receiver is in the boot-off state, the train speed is zero, and the high-speed circuit breaker is in the off state; it is used to control the ...

Abstract

The invention provides a tractive power supply system for a storage battery and a current collector of an urban rail vehicle. The tractive power supply system comprises a monitoring module and a control module; the monitoring module is used for monitoring the state of the current collector of the vehicle, the speed of a train and the state of a high-speed circuit breaker; when the monitoring module detects that the current collector is in a de-shoe state, the speed of the train is zero, and the high-speed circuit breaker is in a disconnecting state; and the control module is used for controlling the vehicle to be converted from the high-voltage power supply mode of the current collector to the power supply mode of the storage battery. When detecting that the high-voltage power supply of a pantograph mode fails or the urban rail vehicle has emergency situation (such as entering a non-electroless region), switching to the power supply mode of the battery storage is conducted. Therefore, dispatching other rescue vehicles is not required, and the urban rail vehicle can continuously run under the power supply mode of the storage battery, thus the rescue tasks are saved, the holding time of the rescue vehicle to a main track on which the train runs is reduced, and further the operating 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 battery and current receiver 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 ti...
