Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings. Terms such as "upper," "lower," "first end," "second end," "one end," "the other end," and the like as used herein to refer to a spatially relative position are used for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The term spatially relative position may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Furthermore, the terms "mounted," "disposed," "provided," "connected," "slidingly connected," "secured," and "sleeved" are to be construed broadly. For example, "connected" may be in a fixed connection, a removable connection, or a unitary construction; may be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements, or components. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

The traditional power modules are basically assembled and integrated, namely, a UPS, a transformer and a low-voltage power distribution cabinet are arranged on the same base side by side. For example, referring to fig. 1, fig. 1 is a schematic diagram of a conventional power module. Referring to fig. 1, a is a UPS, B is a low-voltage power distribution cabinet, C is a base, and 3 UPS and 3 low-voltage power distribution cabinets are mounted on the base, which is not shown in the figure. The length of the power module is at least the sum of the lengths of 3 UPS and 3 low-voltage power distribution cabinets, and the occupied area of the power module is often large.

In practice, because the external dimension difference of the UPS and the low-voltage power distribution cabinet is larger, the appearance of the whole power module is not uniform, and the attractive degree is lower. Alternatively, in order to make the overall power module appearance uniform, it is necessary to add a peripheral frame on the upper or rear of the UPS to complement the dimensional differences. However, hidden danger is brought to the air inlet and outlet heat dissipation of the UPS, the possibility of UPS faults is increased, and the usability of the whole power distribution system is further affected.

The assembled integrated power module has certain economic value although the field construction and the installation period are greatly shortened, but the occupied area of a power distribution room is not reduced. Especially in high density central projects, the total area of the supporting areas such as the distribution room sometimes even exceeds the total area of the IT room. IT is increasingly important and necessary to reduce the area of the distribution room, increase the area occupation ratio of the IT room in the whole room building, deploy more IT cabinets, become a urgent problem to be solved,

in the assembled integrated power module, each UPS and the low-voltage power distribution cabinet are installed in parallel, so that the UPS can not be overhauled or replaced under the condition that the power module is not powered off, and great challenges are brought to the power supply reliability of the whole power module.

Based on this, this application embodiment provides a power module and distribution device, through reducing the distribution space that UPS occupy for power module's length shortens, and then makes power module's area ratio less, has effectively reduced the area of data center supporting zone.

Thereafter, the UPS is maintained within the UPS-installed bay. After the UPS is maintained, after the UPS input switch in the control function unit compartment is closed, the UPS output switch in the control function unit compartment is closed, so that the UPS installation compartment is in an electrified condition. By adopting the scheme, in the maintenance process, the input horizontal copper bars and the output horizontal copper bars in the bus compartment are normally electrified and normally supply power, so that the normal power supply of the whole power module is ensured, and the purpose of improving the power supply reliability of the power module is realized.

Optionally, in the above embodiment, the UPS may be connected to the UPS through an auxiliary contact point in a switching state of the UPS output switch and the UPS input switch, so that after the UPS output switch is switched off, the UPS stops outputting power and sends an alarm signal; when the UPS input switch is disconnected, the UPS interrupts the mains supply and sends out an alarm signal.

Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the utility model disclosed herein. This application is intended to cover any variations, uses, or adaptations of the application following, in general, the principles of the application and including such departures from the present disclosure as come within known or customary practice within the art to which the application pertains.
