▎ 摘　　要

NOVELTY - The device has a high-pressure jet engine utilized for absorbing air from a compression tank through a compressor. The high-pressure jet engine drives a generator for generating electricity. A railway train (5) is connected with a power network (6). An air-powered generator unit (1) is provided with a graphene battery (2). A common power supply is connected with a graphene storage battery group (2) by an intelligent control system (3). The graphene battery is connected with a backup power chamber (4) that is provided between a door and a pedestrian passageway. USE - Electrified railway power backup device. ADVANTAGE - The device is light in weight, and has large power and short charging time and discharging time, and avoids railway train accidental situation during a power network failure condition, continuously maintains low-speed power operation, realizes air conditioning and lighting function and quickly achieves safe station domain evacuation function. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an electrified railway power backup device. Air-powered generator unit (1) Graphene battery (2) Intelligent control system (3) Backup power chamber (4) Railway train (5) Power network (6)
