Summary of the invention
In view of this, be necessary to provide a kind of less rack supply unit of enclosure interior that takies.
A kind of rack supply unit, in order to the some station servers that are installed in the rack are powered, this rack supply unit comprises voltage distribution unit (Power Distribution Unit, PDU) and respectively several power-supply units (Power Supply Unit of arranging of a corresponding server, PSU), described PDU comprises distributing board, plugboard and base plate, described distributing board is connected to plugboard, in order to the three-phase alternating current that will insert from the external world through being distributed into some roads single-phase alternating current, described some PSU are parallel between plugboard and the base plate, and each PSU obtains one road single-phase alternating current from described plugboard, and being sent to base plate after converting this alternating current to server required voltage, this base plate redistributes the voltage that some PSU transmit to each station server.
Described rack supply unit not only is integrated into described PSU in the PDU, and can described PDU be set according to the quantity correspondence of described server, making can be with power distribution to each PSU by single PDU, and need not to arrange a plurality of PDU, and it is less to take described enclosure interior.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See also Fig. 1 and Fig. 2, the rack supply unit 100 of preferred embodiments of the present invention can be simultaneously to being installed in multiple servers 200 power supplies in the rack (not shown).This rack supply unit 100 comprises power distribution unit (Power Distribution Unit, PDU) 10 and some power-supply units (Power Supply Unit, PSU) 30, described some PSU30 are integrated in this PDU10, and electrically connect with this PDU10.Described PDU10 is connected to extraneous three-phase alternating current, and be supplied to each PSU30 after this three-phase alternating current is distributed into the multichannel single-phase alternating current, after converting the power supply that inserts the rated voltage of server 200 to by this PSU30, be supplied to each server 200 by this PDU10 again.
Described PDU10 comprises incoming end 11, distributing board 13, plugboard 15 and base plate 17.Described incoming end 11, distributing board 13, plugboard 15 electrically connect successively, and the opposite end of described some PSU30 is connected to described plugboard 15 and base plate 17 respectively, and are connected to each server 200 by base plate 17.
One end of described incoming end 11 is connected to extraneous three-phase alternating current, and the other end is connected to described distributing board 13, in order to control being connected of this rack supply unit 100 and extraneous power supply.In present embodiment, described incoming end 11 is an isolating switch.
Described distributing board 13 converts three groups of single-phase alternating currents in order to one group of three-phase alternating current that will insert, and then every group of single-phase alternating current is divided into as required the single-phase alternating current of multichannel.In the present embodiment, the way that every group of single-phase alternating current cut apart all equates, is three integral multiple thereby make the total way of single-phase alternating current of this distributing board output.Concrete, the way of the single-phase alternating current of these distributing board 13 outputs determines with the quantity of described PSU30, makes described each PSU30 correspondence that one road single-phase alternating current is set.
Corresponding described PSU30 is provided with some sockets 151 on the described plugboard 15.Described each socket 151 all obtains one road single-phase alternating current from distributing board 13, and is connected to a PSU30, to supply one road single-phase alternating current to described PSU30.
Described some PSU30 and be connected in plugboard 15 and base plate 17 between, convert the required voltage of server 200 in order to the electric energy that plugboard 15 places are inserted, be resent to described base plate 17.
Described base plate 17 reassigns to each server 200 after in order to the voltage parallel connection with each PSU30 output again.So, when described a certain PSU30 can't operate as normal, the PSU30 that this breaks down was replaced in the power supply that can be realized this server 200 to this base plate 17 by other PSU30 normal transmission electric energy simultaneously, and need not to close this rack supply unit 100, in order to avoid influence the operate as normal of this server 200.
Be appreciated that, this rack supply unit 100 also comprises a control panel 50, and it is connected to described base plate 17, and an interface 51 is set, in order to be connected to available data treating apparatus (not shown) such as a main frame, to realize the monitoring to the power supply state of this rack supply unit 100.
See also Fig. 2, below be that example describes with the rack power supply that has 6 station servers 200 by 100 pairs of this rack supply units: the alternating current of three-phase enters distributing board 13 from incoming end 11, being distributed into 6 road single-phase alternating currents by distributing board 13, and every road single-phase alternating current is sent to a socket 151 places in the described plugboard 15.After the PSU30 that is plugged into each socket 151 place converts this single-phase alternating current the rated voltage of server 200 to, be resent to described base plate 17.After the voltage that described base plate 17 transmits each PSU30 is in parallel, be supplied to each station server 200 by supply path again.
As seen, rack supply unit 100 of the present invention not only is integrated into described PSU30 in the PDU10, and can described PDU10 be set according to the quantity correspondence of described server 200, make and to realize power distribution to each PSU30 by single PDU10, and need not to arrange a plurality of PDU10, it is less to take described enclosure interior.
In addition, those skilled in the art can do other variation in spirit of the present invention, and still, all variations of doing according to the present invention's spirit essence all should be included within the present invention's scope required for protection.
