In addition, it should be understood that in the description of this application, words such as "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or imply order.

It should be noted that "coupling" in the embodiments of the present application may be understood as electrical connection, and the coupling of two electrical components may be direct or indirect coupling between two electrical components. For example, the connection between A and B can be direct coupling between A and B, or indirect coupling between A and B through one or more other electrical components, such as A and B coupling, or A and C direct coupling, C and B are directly coupled, and A and B are coupled through C. In some scenarios, "coupling" can also be understood as connection. In short, the coupling between A and B can enable the transmission of electric energy between A and B.

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Referring to Fig. 1, the switches in the UPS system may include a main circuit switch, a bypass switch, an output switch, and a maintenance bypass switch. The following briefly introduces the structure and functions of the UPS system.

The UPS system generally includes a main road part and a bypass part. The main circuit part may include a main circuit input terminal, a main circuit switch and a power module. The main circuit input terminal can be connected to the first power supply. Usually, the first power source is mains power. One end of the main circuit switch is coupled to the main circuit input end, and the other end is coupled to the power module. When the main circuit switch is in a conducting state, it can provide the first power supply electric energy to the power module. The power module performs power conversion processing on the electric energy, such as processing it into stable and reliable electric energy. The power module can also be connected with the battery, if the first power supply fails, it cannot provide electric energy. The battery can be used as a backup power source to provide power to the power module. The power module can perform power conversion processing on the electric energy provided by the battery.

The main circuit part of the UPS system may also include an output switch and a system output terminal. An output terminal of the power module can be connected to an output switch. One end of the output switch is connected to the output end of the power module, and the other end is connected to the system output end. When the output switch is in the on state, the electric energy output by the power module can be provided to the output terminal of the system.

The bypass portion of the UPS system may include a bypass input, a bypass switch, and a static bypass module. The bypass input can be connected to a second power supply. In some scenarios, the first power supply and the second power supply may be the same power supply or different power supplies. One end of the bypass switch is connected to the bypass input end, and the other end is connected to the static bypass module. When the bypass switch is in the on state, the bypass input terminal can be connected with the static bypass module, so that the electric energy provided by the second power supply can be transmitted to the static bypass module. The static bypass module may include one or more bypass static switches. One end of the static bypass module is connected to the bypass switch, and the other end is connected to the output switch. The electric energy provided by the second power supply can be output to the output end of the system through the bypass switch, the static bypass module and the output switch.

In some scenarios, to facilitate maintenance of modules or components in the UPS system, the bypass part of the UPS system may further include a maintenance bypass switch, one end of the maintenance bypass switch is connected to the bypass input end, and the other end is connected to the output switch. When the maintenance bypass switch is in the on state, the electric energy provided by the second power supply is output to the system output terminal through the maintenance bypass switch and the output switch.

Fig. 2(a) is a schematic structural diagram of a switch on an existing UPS cabinet. The existing switch is provided with a switch fixed point, and the switch fixed point is generally arranged on the back side of the switch, and a switch rotating rod is arranged on the front side of the switch. It should be understood that the back and front are two opposing surfaces. The switch has multi-phase terminals, for example three-phase terminals. Terminals A1 , B1 and C1 are arranged laterally on the upper surface of the switch, respectively. Terminals A2, B2 and C2 arranged laterally are arranged on the lower surface of the switch respectively. Terminal A1 and terminal A2 can be used as the A-phase input terminal and output terminal of the switch. Similarly, terminals B1 and B2 can be used as the B-phase input terminal and output terminal of the switch. Terminal C1 and terminal C2 can be used as C-phase input terminal and output terminal of the switch.

The switch rotating rod provided on the front of the switch is used to control the conduction or disconnection state of the switch. The front of the switch is thus close to the front panel of the cabinet. The back of the switch is next to the backplane of the cabinet. In this way, the switch occupies a relatively large horizontal space of the cabinet, which is not conducive to improving the integration degree of the UPS cabinet.

In addition, FIG. 2(b) is a schematic diagram of the arrangement of switches in the existing UPS cabinet. The switches in the existing UPS cabinet are arranged in a "field" shape. Fig. 2(c) shows a schematic diagram of wiring under the "Tian"-shaped arrangement of switches in the UPS cabinet. Due to the horizontal arrangement of the switch terminals, combined with the isolation requirements between the main circuit part and the bypass part, when the switches are arranged in a "Tian" shape, the power wiring of the UPS cabinet is complicated, the cost will increase, and the power density is low.

Wherein, the third surface 41c is a surface close to the front panel of the cabinet. That is, the third surface 41c of the switch assembly 41 is facing the front panel of the cabinet, so that the user can control the on-off state of the switch by controlling the switch operation part. In some scenarios, the switch operation portion provided on the third surface 41c of the switch assembly 41 may be a switch rotation rod.

Usually, the direction in which the first side plate 31 of the cabinet points to the second side plate 32 is horizontal, and the direction in which the top plate 33 of the cabinet points to the bottom plate 34 is vertical. The direction in which the front panel of the cabinet points to the back panel is the depth direction. In the embodiment of the present application, the first direction is the depth direction of the cabinet. Different from the terminals arranged horizontally along the cabinet on the existing switch, in the embodiment of the present application, the terminals of the switch assembly 41 are arranged along the depth direction of the cabinet, which can reduce the horizontal space occupied by the cabinet and help reduce the lateral width of the cabinet.

The second direction is the direction from the first side plate 31 to the second side plate 32 , that is, the plurality of switch assemblies 41 are arranged along the transverse direction. Different from the "Tian"-shaped arrangement of multiple switches in the existing UPS cabinet, the arrangement of multiple switch assemblies 41 in the UPS cabinet provided by the embodiment of the present application along the second direction can support the shortest power routing and reduce the The cost of the UPS cabinet is also conducive to improving the integration of the UPS cabinet.
