成果简介	NOVELTY - The device has feeder input and protection units (1) whose inputs are connected to an automatic power-off unit (7), a uninterruptible power supply (5) and a battery pack. Outputs of the feeder input and protection units are connected to an automatic feeder switching circuit (3). A first output of the automatic feeder switching circuit provides a guaranteed power supply output. A second output of the automatic feeder switching circuit is connected to an isolated transformer (8). An output of a distribution unit (9) is connected in parallel through the manual and automatic bypass circuit and the supply providing an uninterruptible power supply output. A transformer distribution block (11) provides two redundant power supply outputs. The supply is connected to a battery cabinet (6). A set of batteries (10) is connected to an input block (2). USE - Unified three-phase power supply device for use in railway automation and telemetry systems. ADVANTAGE - The device provides uninterrupted and guaranteed power supply to loads from external power sources and various devices of railway automation and telemechanics and eliminates possibility of simultaneously connecting two external power sources to the load. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of the unified three-phase power supply device for railway automation and telemetry systems (Drawing includes non-English language text). 1Feeder input and protection units 2Input block 3Automatic feeder switching circuit 5Uninterruptible power supply 6Battery cabinet 7Automatic power-off unit 8Isolated transformer 9Distribution unit 10Set of batteries 11Transformer distribution block
