Abstract

A portable two-voltage emergency power supply for a rail passenger vehicle and a load automatic detecting method, belonging to a portable emergency power converter and an automatic detection method. The input end of an inverter of the emergency power supply is connected with the DC 600V power supply, the output of the inverter is three-phase output terminal, the input end of a load detector is connected with the three-phase output terminal of the inverter, the output end of the load detector is connected with the input end of a main controller, and the output end of the main controller is connected with the control end of the inverter through a driver. The method is that after the emergency power supply device is automatically detected, the dual-voltage output of 50 Hz AC 380V three-phasepower or DC 110V is realized directly according to a load connected with the output terminal. The advantages are that the emergency power supply device is capable of being compatible with the functions of two primary convertor devices; the output voltage level does not need manual switching, the power supply device can automatically determine the output voltage level according to the wiring mode of the output side and automatically start, the working efficiency is improved, the types of the spare power supplies of the vehicle are reduced and the continuity of power supply is ensured.

Description

technical field [0001] The invention relates to a portable emergency power converter, in particular to a portable two-voltage emergency power source for rail passenger cars. Background technique [0002] At present, the power supply used on rail cars is provided by the DC600V power supply system in a way of centralized power supply and decentralized conversion, that is, the locomotive provides DC600V power supply in a centralized way, and the passenger car performs decentralized conversion; the converter equipment converts the DC600V provided by the locomotive into Three-phase 50Hz AC380V and DC600V converted to DC110V two voltage levels of power supply, of which the three-phase 50Hz AC380V power supply is used for three-phase loads such as air conditioning units; DC110V power supply is used for DC110V loads such as battery charging, lighting and power supply control. [0003] When the inverter equipment fails, in order to ensure the continuity of power supply, the portable ...
