Abstract
The invention discloses a device capable of preventing power outage of a complete set cabinet caused by the failure of the components of secondary power source plates and belongs to the server secondary power source plate power supply filed. The device includes a copper bar, a plurality of fuse, a plurality of secondary power source plates and a plurality of server motherboards; the copper bar is suitable for providing power for the complete set cabinet; and one end of each fuse is connected with the input end of a secondary power source plate corresponding to the fuse, and the other end of each fuse is connected with the copper bar, and the output end of the secondary power source plate is connected with power supply and provides power for a corresponding server motherboard. When the components of the secondary power source plates fail, short-circuit fusing control is carried out through the fuses, and the connection between the copper bar of the complete set cabinet and the secondary power source plates is cut off, and therefore, the risk of the power outage of the complete set cabinet caused by local short circuiting of the secondary power source plates can be avoided, and the complete set cabinet can work more reliably and stably.
Description
Technical field
The present invention relates to server secondary power supply plate for electrical domain, specifically a kind of device preventing secondary power supply plate part failure from causing whole machine cabinet power down.
Background technology
Along with the fast development of the Networks such as the Internet, server starts extensive use in a lot of fields, in server system, secondary power supply plate is indispensable pith, it, in storage class application, needs for rack provides power supply, to ensure that it works normally.And increasing along with number of nodes, larger to the power demand current of 12V of secondary power supply plate; Meanwhile, the requirement of user to the on-line maintenance of secondary power supply plate also improves constantly.Therefore, monomer is bad guarantees whole machine cabinet not power down, ensures system stable operation, above each board being also widely used in server is powered.
At present, in rack rack server system, secondary power supply plate, after power taking whole machine cabinet copper bar, then guarantees voltage stabilization through voltage conversion chip, then powers to respectively corresponding server master board.When system is charged, sometimes need secondary power supply plate is carried out to on-line maintenance, more changes jobs.Secondary power supply plate is inserted on whole machine cabinet copper bar, larger transient current can be produced and pass through connector.Simultaneously, equivalent inductance above secondary power supply plate Copper Foil is larger, transient current can produce forward sense voltage and superpose with input voltage, and the voltage instantaneous of secondary power supply plate input is raised, and this high voltage can cause input capacitance, MOS or hot plug chip pin exceed the withstand voltage scope of safety and damage.
Therefore, at whole machine cabinet copper bar in the power-supply service of secondary power supply, need take safeguard measure, when making secondary power supply plate part failure, whole machine cabinet copper bar is protected, unlikely power down.
Summary of the invention
The present invention is directed to the weak point of current needs and prior art development, a kind of device preventing secondary power supply plate part failure from causing whole machine cabinet power down is provided.
A kind of device preventing secondary power supply plate part failure from causing whole machine cabinet power down of the present invention, the technical scheme solving the problems of the technologies described above employing is as follows: described in prevent secondary power supply plate part failure from causing the device of whole machine cabinet power down, its structure comprises a copper bar, some fuses, some secondary power supply plates and some server master boards, wherein said copper bar is applicable to power to whole machine cabinet, the input of the secondary power supply plate that described fuse one end is corresponding with it connects, the other end is connected with described copper bar, the output of described secondary power supply plate connects power supply to a server master board simultaneously.
Preferably, described secondary power supply plate is arranged on a pcb board, and described pcb board arranges described fuse.
Preferably, described copper bar adopts 12V to power, and the pcb board that secondary power supply plate is connected with copper bar arranges the fuse of appropriate size, and described fuse is met the guard time when being greater than 200A by electric current and is shorter than 60ms.
A kind of beneficial effect preventing secondary power supply plate part failure from causing the device of whole machine cabinet power down compared with prior art to have of the present invention is: the present invention passes through in whole machine cabinet copper bar and secondary power supply plate junction, a fuse is added at secondary power supply plate input, can realize under the application scenarios of secondary power supply plate centrally connected power supply, when secondary power supply plate part failure, circuit fusing control is carried out by fuse, the connection of cutting rack copper bar and secondary power supply plate, can evade because secondary power supply plate partial short-circuit causes whole machine cabinet power down risk, and then ensure whole machine cabinet not power down, ensure the work that RACK whole machine cabinet can be more reliable and stable, meanwhile, can ensure when hot plug operations, even if there is the partial short-circuit problem that secondary power supply plate part failure causes, also can ensure system worked well.
Accompanying drawing explanation
The structured flowchart of accompanying drawing 1 for preventing secondary power supply plate part failure from causing the device of whole machine cabinet power down.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, a kind of device preventing secondary power supply plate part failure from causing whole machine cabinet power down of the present invention is further described.
The invention provides a kind of device preventing secondary power supply plate part failure from causing whole machine cabinet power down, at whole machine cabinet copper bar on secondary power supply plate circuit footpath, at secondary power supply plate input, increase a fuse, connect copper bar with this fuse and secondary power supply plate inputs.When secondary power supply plate part failure causes input short, fuse can quick-break, and cut off the connection of copper bar and secondary power supply plate, the not power down of guarantee copper bar, can ensure system worked well.
Embodiment:
