Title:
DUAL-POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/078047
Kind Code:
A1
Abstract:
Disclosed is a dual-power supply system, comprising a main circuit for power supply from overhead contact lines, a main circuit for power supply from diesel engine sets which works at a different time from the main circuit for power supply from overhead contact lines, a rectification inversion module which performs rectification and inversion on the power input by itself, a power supply switching device for receiving a command on power supply from overhead contact lines or diesel engine sets, and a controller. Hence, the dual-power supply system of the present application is applicable to two mutually independent power supply modes using overhead contact lines or diesel engine sets, and realizes the automatic switching of the two power supply modes by using the switching command of the power supply switching device and the controller. Therefore, the present application may select the mode of power supply from overhead contract lines in an area with electricity, and switch to the mode of power supply from diesel engine sets in an area without electricity so that an electric driven engine can still work normally; and the dual-power supply system of the present application realizes the alternative use of two power supply modes, thus ensuring longer and more environment-friendly use in comparison with the sole mode of power supply from diesel engine sets.
