Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, an intelligent power supply switching system includes an ac output terminal 1 and a diesel generator set 2 for providing power, the diesel generator set 2 is connected to the ac output terminal 1 through a generator set controller 3, the diesel generator set 2 or the ac output terminal 1 provides power to an ac electric device 4 and a dc regulated power supply 5, the dc regulated power supply 5 is connected to and charges a storage battery 6, the dc regulated power supply 5 and the storage battery 6 are electrically connected to a dc electric device 8 and supply power to the dc electric device 8, and the ac output terminal 1 and the diesel generator set 2 stop providing power in a state where the storage battery 6 supplies power to the dc electric device 8.
In addition, when the alternating current output end 1 provides power, the generator set controller 3 turns off the diesel generator set 2; after the alternating current output end 1 stops supplying power, the generator set controller 3 automatically controls the diesel generator set 2 to start supplying power.
In addition, the generator set controller 3 is provided with a UPS switch, and the UPS switch is automatically switched to the output of the diesel generator set 2 after the power supply of the alternating current output end 1 is stopped.
