Title:
HIGH-VOLTAGE CIRCUIT FOR SECURITY TRANSITION FROM THIRD RAIL POWER SUPPLY TO INTRA-GARAGE POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2016/082650
Kind Code:
A1
Abstract:
A high-voltage circuit for security transition from a third rail power supply to an intra-garage power supply. The high-voltage circuit comprises current collectors, inter-vehicle power sources, high-voltage buses, power supply buses of the inter-vehicle power sources and main switches. The inter-vehicle power sources are all connected to the power supply buses of the inter-vehicle power sources, so as to supply power to vehicles. Each of the main switches is a double-pole double-throw switch, a switch S1 in the main switch can be thrown to an end point P1 or P2, and a switch S2 can be thrown to an end point P3 or P4; the end point P1 of the main switch in each carriage is connected to each of the high-voltage buses, and the end point P2 is connected to each of the power supply buses of the inter-vehicle power sources, so as to achieve isolation between the high-voltage buses and the power supply buses of the inter-vehicle power sources; the end point P3 is connected to a traction power consumption end or a power consumption end of an auxiliary power source; and the end point P4 is grounded. A contactor K1 is arranged on each of the high-voltage buses. The high-voltage circuit can achieve the security transition from the power supply of current collectors to the power supply of power sources for garages, and therefore the security of a maintainer can be ensured, and the security and reliability of the maintenance operation can be ensured.
