High Voltage Circuit for the safe Transition from the Third Rail to Power Source Energy Sources Shed

摘要

The present Disclosure provides a high-voltage Circuit for Safe Transition from a Power Source of the Third Rail power sources of the shed. The Circuit includes a current collecting Workshop, electrical feeds, a High Voltage bus, a bus power supply for the Electric Supply of Workshop and main switches.Each workshop is connected to the Electric Supply bus power supply for the electrical power supplied to the railway Workshop. The main switches are bipolar bidirectional switches.The Switch S1 of each of the main switches can be switched to a Terminal Point to a Terminal Point P1 or P2 and S2, The Switch can be switched to a Terminal Point to a Terminal Point P3 or P4.For the main Switch in each car, the terminal Point P1 is connected to the High Voltage bus and the point P2 Bus Terminal connects to the power supply for the Electric Supply of Workshop in order to realize the isolation between the High Voltage bus and the bus Power supply to the electrical power WorkshopThe Terminal Point P3 port is connected to a power consumption of Traction equipment of the train or a Port of power consumption of a computer Auxiliary Power Supply, and the terminal Point P4 is connected to Earth. Provides a contactor K1 in the High Voltage bus.The Circuit in accordance with the present Disclosure can realize the safe Transition from be fed through current Collectors to be Powered by Energy Sources Shed, ensuring that the Safety and security of Peacekeeping Personnel and fi Ability of maintenance tasks.
