Technical Field

The application relates to the technical field of electronics, in particular to an uninterruptible power supply cabinet.

Background

Fig. 1 shows the switch connection in an uninterruptible power supply (uninterruptible power supply, UPS) system. For UPS systems with power greater than 400KW and capable of supporting near-end power outages, a main switch, a bypass switch, an output switch, and a maintenance bypass switch are typically configured. The UPS system can be used as power supply equipment, the main switch is connected with a power supply, the power supply of the power supply can be transmitted to the power module, and the power module converts the power supply of the power supply into stable and reliable electric energy and then provides the electric energy for a load through the output switch. If the power supply connected with the main switch is abnormal, the battery in the UPS system can be used as a standby power supply, and the power module converts battery power into stable and reliable electric energy and then provides the electric energy for a load through the output switch.

The bypass switch may also be connected to a power source. If the power module fails, the bypass switch can transmit the power supply to the static bypass module, and the load is supplied with power through the static bypass module and the output switch. And if the power module and the static bypass are maintained, closing a maintenance bypass switch, and transmitting power supply to the output switch by the maintenance bypass switch.

The UPS system has a large number of switches and is an isolating switch, namely, the switch can meet the requirement of a specified isolating function in an off state, and can be connected and bear current under the normal circuit condition. And under non-specified normal circuit conditions (e.g., short circuit), the switch is capable of carrying current for a specified time. The space occupied by such a switch is large. In the switch arrangement mode in the existing UPS cabinet, the cabinet is required to have a larger transverse space, so that the whole space of the UPS cabinet is larger. The existing UPS cabinet has low integration level and increased cost.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings. The specific method of operation in the method embodiment may also be applied to the device embodiment or the system embodiment. In the description of the present application, "at least one" means one or more, wherein a plurality means two or more. In view of this, the term "plurality" may also be understood as "at least two" in the embodiments of the present application. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/", unless otherwise specified, generally indicates that the associated object is an "or" relationship. In addition, it should be understood that in the description of this application, the words "first," "second," and the like are used merely for distinguishing between the descriptions and not for indicating or implying any relative importance or order.

It should be noted that "coupled" in embodiments of the present application is understood to mean electrically connected, and that two electrical components may be coupled directly or indirectly between the two electrical components. For example, a may be directly coupled to B, or indirectly coupled to B through one or more other electrical components, such as a may be directly coupled to B, or directly coupled to C, which may be directly coupled to B, where coupling is achieved through C. In some cases, "coupled" may also be understood as connected. In summary, coupling between a and B may enable the transfer of electrical energy between a and B.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Referring to fig. 1, the switches in the ups system may include a main switch, a bypass switch, an output switch, and a maintenance bypass switch. The structure and function of the UPS system will be briefly described.

UPS systems generally include a main circuit portion and a bypass portion. The main circuit portion may include a main circuit input, a main circuit switch, and a power module. The main input may be connected to a first power source. Typically, the first power source is mains. One end of the main way switch is coupled with the main way input end, and the other end is coupled with the power module. When the main switch is in a conducting state, the first power supply electric energy can be provided to the power module. The power module performs power conversion processing on the electric energy, for example, processing the electric energy into stable and reliable electric energy. The power module may also be connected to a battery, and may not provide power if the first power source fails. The battery may be used as a backup power source to provide power to the power module. The power module can perform power conversion processing on electric energy provided by the battery.

The main circuit portion of the UPS system may also include an output switch and a system output. The output of the power module may be connected to an output switch. One end of the output switch is connected with the output end of the power module, and the other end of the output switch is connected with the output end of the system. When the output switch is in a conducting state, the electric energy output by the power module can be provided to the output end 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 may be connected to a second power source. In some scenarios, the first power source and the second power source may be the same power source or may be different power sources. One end of the bypass switch is connected with the bypass input end, and the other end of the bypass switch is connected with the static bypass module. When the bypass switch is in a conducting state, the bypass input end can be communicated with the static bypass module, so that electric energy provided by the second power supply is 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 with the bypass switch, and the other end of the static bypass module is connected with the output switch. The electric energy provided by the second power supply can be output to the system output end through the bypass switch, the static bypass module and the output switch.

In some scenarios, to facilitate maintenance of a module or component in the UPS system, the bypass portion of the UPS system may further include a maintenance bypass switch having one end connected to the bypass input and the other end connected to the output switch. When the maintenance bypass switch is in a conducting state, the electric energy provided by the second power supply is output to the system output end through the maintenance bypass switch and the output switch.

Fig. 2 (a) is a schematic diagram of a switch on a conventional UPS rack. The existing switch is provided with a switch fixing point, the switch fixing point is generally arranged on the back of the switch, and the front of the switch is provided with a switch rotating rod. It is understood that the back face is the opposite surface to the front face. The switch has a multi-phase terminal, such as a three-phase terminal. The upper surface of the switch is provided with a terminal A1, a terminal B1 and a terminal C1 which are arranged laterally. A terminal A2, a terminal B2, and a terminal C2 are arranged in a lateral direction on the lower surface of the switch, respectively. Terminal A1 and terminal A2 may serve as the a-phase input and output of the switch. Similarly, terminals B1 and B2 may serve as B-phase inputs and outputs of the switch. Terminals C1 and C2 may serve as the C-phase input and output of the switch.

And a switch rotating rod arranged on the front surface of the switch is used for controlling the on or off 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 close to the back plate of the cabinet. Thus, the switch occupies a larger transverse space of the cabinet, which is not beneficial to improving the integration level of the UPS cabinet.

In addition, fig. 2 (b) is a schematic diagram of a switch arrangement in a conventional UPS cabinet. The switches in the existing UPS cabinet are arranged in a 'field' -shaped. Fig. 2 (c) shows a schematic diagram of the routing of the switch in the UPS cabinet in a "field" configuration. Because each switch terminal is transversely arranged and combines the isolation requirement between the main path part and the bypass part wiring, when the switch is distributed in a Chinese character 'tian' shape, the power wiring of the UPS cabinet is complex, the cost can be increased, and the power density is lower.

In view of this, the embodiments of the present application provide a UPS cabinet with smaller occupied space, higher integration and lower cost. The UPS cabinet may include a front panel, including a front panel, a back panel, a first side panel, a second side panel, a top panel, and a bottom panel. Fig. 3 (a) is a front view of a UPS cabinet, where a front plate, a back plate, a first side plate 31, the second side plate 32, the top plate 33, and the bottom plate 34 of the UPS cabinet may form a first space. The cabinet further comprises a plurality of switch assemblies 41, at least one power module 51. The first space may accommodate the plurality of switching assemblies 41 and the at least one power module 51.

The structure of any one of the plurality of switch assemblies 41 may be as shown in fig. 3 (b). The first surface 41a of the switching assembly 41 may be provided with a plurality of first terminals Q arranged in a first direction, and the second surface 41b opposite to the first surface 41a may be provided with a plurality of second terminals P arranged in the first direction. The first direction is the direction from the front plate to the rear plate. The third surface 41c of the switch assembly 41 is provided with a switch operating portion for controlling the on-off state of the switch. Wherein the third surface 41c is a surface close to the cabinet front. I.e. the third surface 41c of the switch assembly 41 faces the front plate of the cabinet, so that the user can control the on-off state of the switch by controlling the switch operation part. In some cases, the switch operating portion provided on the third surface 41c of the switch assembly 41 may be a switch rotating lever.

Typically, the direction in which the first side plate 31 of the cabinet points to the second side plate 32 is transverse, and the direction in which the top plate 33 of the cabinet points to the bottom plate 34 is vertical. The direction of the front plate of the cabinet pointing to the back plate is the depth direction. In this embodiment of the present application, the first direction is a depth direction of the cabinet. In the embodiment of the present application, the terminals of the switch assembly 41 are arranged along the depth direction of the cabinet, so that the occupation of the transverse space of the cabinet can be reduced, and the transverse width of the cabinet can be reduced.

In one possible design, routing complexity is reduced for power routing of a UPS cabinet. The plurality of switch assemblies 41 in the UPS cabinet provided in the embodiment of the present application are arranged along the second direction. Wherein the second direction is the direction from the first side plate 31 to the second side plate 32, i.e. the plurality of switch assemblies 41 are arranged in the lateral direction. The mode that a plurality of switch components 41 in the UPS rack provided by the embodiment of the application are arranged along the second direction can support the shortest power routing path, reduce the cost of the UPS rack and also be beneficial to improving the integration level of the UPS rack. The following is a detailed description.

As shown IN fig. 4, a UPS cabinet provided IN an embodiment of the present application may include a first input interface IN1 and an output interface OUT. The first input interface IN1 may be implemented as the aforementioned main input. The output interface OUT may be implemented as the aforementioned system output.

A first switch assembly 41N1 of the plurality of switch assemblies 41 is coupled with the first input interface IN1 and with the at least one power module 51, the first switch assembly 41N1 being configured to connect or disconnect the first input interface IN1 to or from the at least one power module. Any one of the at least one power module 51 is coupled to the output interface OUT for power conversion of the first electrical energy. The output interface OUT may be used to couple with a load.

The plurality of switching components 41 may further include a second switching component 41N2. The any one of the power modules 51 is coupled to the output interface OUT through the second switching component 41N2. An output of any of the power modules 51 may be coupled to the output interface OUT through the second switching component 41N2. The second switching assembly 41N2 may be implemented as the aforementioned output switch. The second switch assembly 41N2 may connect or disconnect any of the power modules to or from the output interface OUT.

The UPS cabinet provided in the embodiment of the present application may further include the bypass portion. In some examples, as shown in fig. 3 (a), the UPS rack may also include a bypass module 61. The bypass module 61 may be implemented as the aforementioned static bypass module. The UPS rack may also include a second input interface. As shown IN fig. 4, the second input interface IN2 may be implemented as the aforementioned bypass input. The second input interface IN2 may be used to receive a second power or to receive the first power. The second input interface IN2 receives the first power, i.e. the second input interface IN2 is coupled to the same power supply as the first input interface IN 1. For another example, the second input interface IN2 receives the second power, that is, the second input interface IN2 and the first input interface IN1 are respectively coupled to different power sources.

The plurality of switching components 41 may further include a third switching component 41N3. The third switching assembly 41N3 may be implemented as the aforementioned bypass switch. A third switching assembly 41N3 is coupled with the second input interface IN2 and with the bypass module 61, the third switching assembly 41N3 being operable to connect or disconnect the second input interface IN2 with the bypass module 61. The bypass module 61 is coupled to the output interface OUT or coupled to the output interface OUT through the second switching assembly. The bypass module 61 may be configured to transfer electrical energy received by the second input interface IN 2.

The plurality of switch assemblies 41 in the UPS cabinet provided in the embodiments of the present application further includes a repair bypass switch assembly 41N4 for facilitating maintenance of the UPS cabinet. IN some examples, as shown IN fig. 4, the repair bypass switch assembly 41N4 is coupled with the second input interface IN2 and with the output interface OUT, and the repair bypass switch assembly 41N4 is configured to connect or disconnect the second input interface IN2 to or from the output interface OUT.

IN other examples, the repair bypass switch assembly 41N4 may be coupled with the second input interface IN2 and with the second switch assembly 41N2. The service bypass switch assembly 41N4 may be used to connect or disconnect the second input interface IN2 to or from the second switch assembly. In some possible scenarios, the switch operator that repairs the third surface 41c of the bypass switch assembly 41N4 may be an operator panel. A protective cover may be further provided on the third surface 41c of the maintenance bypass switch assembly 41N4 for placing the operation panel in error operation.

In a possible embodiment, referring again to fig. 4, the first switch assembly 41N1 may be the first switch assembly along the second direction. The second switching element 41N2 may be the last switching element in the second direction.

In some examples, a UPS rack may include a first switch assembly 41N1, a second switch assembly 41N2, and a third switch assembly 41N3. As shown in fig. 5 (a) and 5 (b), the arrangement of the plurality of switch assemblies 41 in the second direction may be the first switch assembly 41N1, the third switch assembly 41N3, and the second switch assembly 41N2. IN fig. 5 (a), the first input interface IN1, the second input interface IN2, and the output interface OUT are all disposed on a side of the first surface 41a of each switch assembly 41 near the top plate 33 of the UPS rack. The bypass module 61 and the power module 51 may be disposed on a side of the second surface 41b of each switch assembly 41 proximate to the backplane 34 of the UPS rack. As another example, IN fig. 5 (b), the first input interface IN1, the second input interface IN2, and the output interface OUT are all disposed on a side of the second surface 41b of each switch assembly 41 near the bottom plate 34 of the UPS rack. The bypass module 61 and the power module 51 may be disposed on a side of the first surface 41a of each switch assembly 41 proximate to the ceiling 33 of the UPS rack. In such a design, the power routing in the UPS cabinet is shortest, so that the UPS cabinet has lower cost. The positions of the power module 51 and the bypass module 61 in the UPS cabinet can be flexibly adjusted as required.

In other examples, a UPS rack may include a first switch assembly 41N1, a second switch assembly 41N2, and a repair bypass switch assembly 41N4.

IN fig. 5 (c), the first input interface IN1, the second input interface IN2, and the output interface OUT are all disposed on a side of the first surface 41a of each switch assembly 41 near the top plate 33 of the UPS rack. The bypass module 61 and the power module 51 may be disposed on a side of the second surface 41b of each switch assembly 41 proximate to the backplane 34 of the UPS rack. For another example, IN fig. 5 (d), the first input interface IN1, the second input interface IN2, and the output interface OUT are all disposed on a side of the second surface 41b of each switch assembly 41 near the bottom plate 34 of the UPS rack.

In still other examples, the UPS rack includes a first switch assembly 41N1, a second switch assembly 41N2, a third switch assembly 41N3, and a repair bypass switch assembly 41N4.

The terminals on the first surfaces 41a of the first switch component 41N1, the third switch component 41N3 and the second switch component 41N2 are connected with the same connecting terminal, so that the input power routing is shortest. The terminals of the second surface 41b of the first switching component 41N1 may be coupled with the first copper bar. The first copper bar can be in a bending form. The first copper bar may couple the power module 51 through a cable. The terminals of the second surface 41b of the third switch assembly 41N3 may be coupled with the second copper bar, and the second copper bar may be in a bent shape. The second copper bar may be coupled to the power module 51 by a cable.

In one possible design, the UPS cabinet further includes a mounting plate. The mounting plate may be mounted to a back plate of the UPS. And a plurality of the second mounting portions are provided on the fixing plate. The second mounting portions provided on the fixing plate may be matched with the first mounting portions M provided on the switch assemblies 41, so as to fix the switch assemblies 41.

In some examples, the second mounting portion provided on the fixing plate may be a guide rail, such as the hatched portion in fig. 4.
