Description

Modular power access system of data center mainframe system cabinet

Technical Field

The invention relates to the technical field of power distribution of cabinets of a data center, in particular to a modular power access system of a cabinet of a main computer room system of the data center.

Background

With the rapid development of super computing and big data application, the density of system equipment in a data center machine room is rapidly increased, and the energy efficiency requirement of the system equipment on a power distribution system of the machine room is higher and higher. The power distribution system used as a machine room is a power foundation for the operation of the whole system equipment, and from the last 80 th century to the present, the power distribution system of a main machine room is continuously developed towards the directions of integration, refinement and standardization.

The utility model discloses a commercial power distribution module, a UPS power distribution module and a base in the patent application number of 201920965964.8 and the patent name of 'a distribution device for a modular data center machine room', wherein the commercial power distribution module and the UPS power distribution module are respectively and independently arranged and are prefabricated, a plurality of installation spaces are arranged on the base, the commercial power distribution module and the UPS power distribution module are convenient to install, and the utility model has the advantages of short construction period and high reliability; the patent application number is '201620332891.5', the patent name is 'container type power transformation and distribution unit for data center', the container is disclosed, metal closed switch equipment, a dry type transformer, a low-voltage power distribution cabinet and the like are arranged in the container, a plurality of low-voltage power distribution cabinets are arranged, an automatic change-over switch is arranged in one low-voltage power distribution cabinet, the reliability of power supply is guaranteed, the transportability is strong, and the modularization degree is high; all of the above patents are modular backup power supply technical solutions designed based on the stability of power supply.

At present, the power distribution mode adopted by a data center mainframe room comprises a special line mode and a bus mode, and the power access modes are different. The special line mode belongs to the traditional power distribution mode of a machine room, namely a special power line is configured for each system cabinet, in the special line mode, a cabinet power access system accesses a power cable into a system cabinet PDU through an industrial connector or directly, and the control and monitoring of each cabinet power line are centralized in a precise power distribution cabinet (a three-level power distribution cabinet). The power access in such modes has the following drawbacks:

1. the efficiency is low and there is no flexibility, and the power that inserts can only be set according to a fixed load value. In the initial construction stage, the load capacity of system equipment cannot be accurately estimated, so that the invalid investment proportion and the system operation risk are increased due to excessive investment in the early stage or repeated investment in the later stage; 2. in the special line mode, the control of each cabinet power loop is centralized in the precise power distribution cabinet, so that the three-phase balance is not easy to flexibly adjust in system application, and the management difficulty of a power distribution system is high; 3. in the special line mode, the power access cables are in a radial wiring mode, the cables at the front section of the bridge are densely arranged, and the tail end bridge is too sparse, so that the resource utilization of the bridge is uneven. Meanwhile, the requirements of the number and the weight of the cables on the specification of the bridge are high, so that the space of a wiring layer of a machine room is enlarged; 4. the intensive arrangement of cable of special line mode makes the cable heat dissipation obstructed and causes the cable to cross the flow and reduce. Once the binding of the cable is finished, the cable is difficult to adjust and replace during operation and maintenance, and the cable is extremely inconvenient to maintain; 5. the number of the three-level switch cabinets of the machine room is increased by the aid of the plurality of special line loops, precious system positions are occupied, and due PUE efficiency of the machine room is reduced.

The bus mode is to configure a power line for one cabinet group in the form of a trunk line. The capacity of a single cabinet in the cabinet group can be flexibly adjusted according to the system requirement. Although the bus capacity is also configured according to the planning of system application, the bus capacity improves the upper limit of the load of a single cabinet and increases the flexibility of system equipment expansion. The existing bus mode system adopts a rail type small bus bar system, namely a bus mode that copper bars are fixed in an aluminum alloy rail to be integrally distributed is implemented, and the tail end power access adopts a gooseneck type rotary connecting plug column on an electrical connection box to be connected with the bus bar in the rail. The power output is transferred to the cabinet PDU through an industrial connector arranged on the connecting box. The control and the electric quantity monitoring of each power circuit are completed in the electric connection box. Therefore, the capacity of the system cabinet in the later period can be expanded only by changing the switch capacity in the electrical connection box. In addition, a precise power distribution cabinet (three-level switch cabinet) is not required to be arranged in a bus mode, and the application efficiency of the machine room system is improved. The characteristics determine that a bus power supply mode is a development trend of a future data center room power distribution system. However, the bus bar system in the form of the small bus bar still has the following defects in the power access:

1. the electrical connection and plug-in box in the small busbar system adopts a non-standard gooseneck type rotary connection and plug-in mode, the power output of the electrical connection and plug-in box is transferred to the cabinet PDU through an industrial connector with a large volume, all power access equipment at the tail end is suspended on the rotary connector, and the requirements of the electrical equipment on the firmness and reliability of the installation process are not compounded; 2. the national standard's data center computer lab 2N's power distribution system requires, need dispose 2 sets of little female systems of arranging respectively above the rack, also need install 2 sets of electrical connection box respectively simultaneously, and its individualized outward appearance and mounting process have invaded a large amount of spaces above the rack, have increased the degree of difficulty for the cable management work that originally is complicated, are unfavorable for the standardized management of data center computer lab. 3. In the small busbar system, a precise power distribution cabinet is omitted, and meanwhile, a wire inlet box of a small busbar starting end and a main control box for collecting electric quantity data are added, so that the application of the whole machine room space is more fragmented and more complicated; 5. the power access in the rail type small busbar system mode can only adopt a single-way electrical connection box. 6. The rail type small busbar system material is made of nonstandard aluminum alloy profiles, the aluminum alloy profiles are embedded into the copper bars and are subjected to insulation treatment, the system assembly components are multiple, the process is complex, and the construction and operation and maintenance costs are high.
