MULTI-SYSTEM EMU HIGH-VOLTAGE POWER SUPPLY SYSTEM AND TRAIN

摘要

Provided is a multi-system EMU high-voltage power supply system, comprising: a DC pantograph and an AC pantograph for obtaining from the power supply network a supply of power from the corresponding system; an isolating switch connected to the DC pantograph, wherein, it disconnects the DC pantograph when determining that a current of the non-DC system power supply flows therethrough; a DC high-voltage box connected to the isolating switch for disconnecting the isolating switch when detecting that the voltage and current flowing through do not meet the DC power supply requirement; an AC high-voltage box, connected to the AC pantograph, for detecting whether the voltage and current flowing through meet the AC power supply requirement, and disconnecting the AC pantograph when the AC power supply requirement is not met. Further provided is a train using the above-described multi-system EMU high-voltage power supply system. The present invention can switch between the electric energy of different systems to supply power to train equipment, and thus train changes are not required when crossing from one region into another.
