Drawings
The contents of the expressions in the various figures of the present specification and the labels in the figures are briefly described as follows:
fig. 1 is a schematic diagram of the structure of the power supply system of the present invention.
Detailed Description
The following description of preferred embodiments of the invention will be made in further detail with reference to the accompanying drawings.
The two UPS circuits are provided with a main loop and a bypass power supply by incoming line power supplies from two sections of different voltage supply circuits, and are mutually crossed; the DCS of the redundant double-circuit power supply circuit is respectively supplied with power by two different UPS; redundant power supply switching devices are added to computer terminals such as a server and an operation station, and two incoming power supplies are respectively from two different UPSs.
As shown in fig. 1, a dual UPS power supply system includes two UPS power distribution cabinets: UPS1, UPS2, every UPS switch board include major loop and next door, and power supply system still includes two way inlet wire power: 1# power supply, 2# power supply, 1# power supply inlet power supply is taken from 1# transformer, and 2# power supply inlet power supply is taken from 2# transformer. Main loop of UPS: and the UPS is used for inverting and rectifying the power supply loop. UPS bypass: UPS internal utility power bypass or maintenance utility power bypass. The output end of the 1# power supply is respectively connected with the input end of a main loop of the UPS1 and the bypass input end of the UPS 2; the output end of the No. 2 power supply is respectively connected with the input end of a main loop of the UPS2 and the input end of a bypass of the UPS 1; the output end of the UPS1 and the output end of the UPS2 are respectively connected with electric equipment and used for supplying power to the electric equipment. The output end of the UPS1 and the output end of the UPS2 are connected with electric equipment through a two-way power supply switching device. The two-way power supply switching device adopts a switching switch device for switching the UPS1 or the UPS2 to be connected with power supply, and can adopt TS switching equipment if. The electric equipment comprises a computer terminal and/or industrial control equipment,
an output terminal row B of the output terminal row A, UPS2 of the UPS1 is connected to a power input of the industrial DCS cabinet through the terminal row a and the terminal row B, respectively. Two incoming power supplies are respectively taken from two transformers. Therefore, the power supply safety coefficient of an industrial field can be greatly improved. Any section of transformer power supply line can normally run and work when the UPS is out of power; when any UPS equipment is in failure shutdown, the production control system still has at least one other UPS providing effective power supply guarantee, thereby avoiding the loss of an industrial field caused by the possible power supply failure. And the UPS equipment is overhauled at any time and any place when the UPS equipment breaks down, and the power supply can be recovered after the overhauling is finished, so that a good and stable power supply guarantee is provided to the production control system to the maximum extent.
