All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 2, a schematic structural diagram of a power supply system for an operation station provided in an embodiment of the present application includes:
control switch 100, rectifying device 200, battery 300, and operator station 400.
The first input end of the control switch 100 is connected to the utility power a, the second input end is connected to the utility power B, and the output end is connected to one end of the rectifying device 200, so as to control any one of the utility power a and the utility power B to supply power to the operation station 400.
In the embodiment of the present application, the control switch 100 includes, but is not limited to, a dual power switch.
The other end of the rectifying device 200 is connected to the operation station 400, and is configured to convert the ac power provided by the utility power a and the utility power B into dc power and output the dc power to the operation station 400.
In the embodiment of the present application, the rectifying device 200 includes, but is not limited to, a rectifier. It should be noted that the number of the rectifiers may be one or more.
The battery 300 is connected in parallel with the rectifier device 200, and the output end of the battery 300 is connected with the operation station 400, and is used for outputting direct current to the operation station 400 under the condition that the rectifier device 200 cannot supply power to the operation station 400.
In the embodiment of the present application, the battery 300 includes, but is not limited to, a secondary battery. Further, the number of the operation stations 400 may be one or more. When the number of the operation stations 400 is plural, each of the operation stations 400 is connected to the battery 300 and the rectifying device 200, respectively.
It should be noted that, the inverter and the static switch are eliminated in the solution provided by this embodiment, so that the structure of the power supply system is simplified, and the reliability of the power supply circuit of the operation station is higher. The rectifying device 200 is connected with the storage battery 300 in parallel and is respectively connected with the operation station 400, the rectifying device 200 and the storage battery 300 form a redundancy relation, any one of the rectifying device 200 and the storage battery 300 is interrupted or fails, and the other one can also work independently, so that an 'uninterruptible' power supply is realized in a true sense, the reliability of power supply of the operation station is further improved, and the economic loss caused by power loss of a power supply system to the operation station is reduced.
Compared with the prior art, the scheme of the embodiment has a simple structure, namely, compared with the power supply mode of the existing operation station, the scheme of the embodiment reduces an inverter and a static switch.
Secondly, the scheme of this embodiment is highly reliable, that is, in the existing power supply mode of the operation station, a series connection relationship exists among a rectifier, a storage battery and an inverter inside the UPS, and any fault can cause power supply interruption, the storage battery of the UPS cannot directly output direct current to the operation station, and the storage battery functions sufficiently and cannot directly protect power supply of the operation station.
In addition, the existing power supply mode of the operation station is complex in system and difficult to modularize, design and construction are still in a manual stage, the system is difficult to change and expand according to one-time investment of planned capacity, in addition, because each component of the alternating current UPS has the characteristics of multiple suppliers and non-standardization, equipment fault repair is difficult, and maintenance time is long, but the power supply system of the operation station shown in the embodiment can flexibly configure the operation number of the rectifier modules by a monitoring system or an operator according to output load capacity, so that the load rate and the conversion efficiency of the system are improved, in the aspect of operation and maintenance, the rectifier modules adopt an 'N + 1' configuration mode, so that field replacement and expansion are convenient, and online maintenance is supported.

The ATS has a first input end connected with the mains supply A, a second input end connected with the mains supply B, and an output end connected with one end of the AC/DC for controlling any one of the mains supply A and the mains supply B to supply power to the operation station.
The other end of the AC/DC is connected with the operation station and is used for converting alternating current provided by the commercial power A and the commercial power B into direct current and outputting the direct current to the operation station.
The storage battery is connected with the AC/DC in parallel, and the output end of the storage battery is connected with the operation station and used for outputting direct current for the operation station under the condition that the AC/DC cannot supply power for the operation station.
