Description
Technical field
The present invention relates to a kind of power-supply device, relate in particular to a kind of be applied to the three phase mains of accepting many types of formula of data center and the power distribution unit of single phase poaer supply (Power Distribution Unit, PDU).
Background technology
Along with the progress of computer science and technology and the fast development of the Internet, the service or the function that provide by the Internet are also more and more many, therefore, the data center (data center) that is made up of many computers or server (server) also increases fast, data center is in order to provide more service or function on the internet, must increase the computer of data center or the number of server, and problems such as the supply of electric power of data center and distribution are also following.
For problems such as the supply of electric power that solves data center and distribution, data center utilizes power distribution unit to distribute every computer or the required electric power of server.Yet, the position difference that each data center is provided with, correspondence makes the civil power kind that provides to data center also inequality, the conventional power source allocation units must be built the initial stage of putting in data center, the civil power kind that the position the provided correspondence that is provided with according to data center designs exclusive power distribution unit, therefore, the power distribution unit at different pieces of information center can't exchange use each other.
Under globalization tendency now, international enterprise-like corporation can be separately positioned on a plurality of data centers different country or regional, makes data center's rate ground operation more quickly and effectively.But, each country or regional city's electrical specification difference that provides, so city's electrical specification of 220 volts of 120/400 volt (V) of three-phase (Φ) four-wire type or single-phase TW two wires for example is the exclusive design of city's electrical specification that the power distribution unit of each data center is provided according to this country or zone.When the power distribution unit fault, the attendant need select corresponding power distribution unit for use according to city's electrical specification, more increases manufacturing cost except causing difficult in maintenance.
In order to improve the overall operation efficiency of data center, need in time change national or regional that data center is provided with, because the data center position after changing, city's electrical specification also changes relatively, even power distribution unit originally not fault also method do not have and continue to use, must choose the power distribution unit of redesign, except increasing the change cost, more cause the wasting of resources.
With manufacturer, for the power distribution unit of multiple city electrical specification is provided, the all component of each city's electrical specification power distribution unit correspondence needs redesign, the product of power distribution unit has the assembly of a plurality of specifications, except the complexity that causes assembling increased, the assembly of a plurality of specifications also can make manufacturing cost improve.
Therefore, how to develop a kind of power distribution unit that improves above-mentioned known technology defective, real problem for the correlative technology field technical staff solution that presses at present.
Summary of the invention
The object of the present invention is to provide a kind of three phase mains of many types of formula and power distribution unit of single phase poaer supply accepted, and can be suitable for multiple city electrical specification, when being applied to data center, the attendant can be by changing corresponding power supply input module (power cord) and/or input power distribution assembly (wiringblock), make the power distribution unit at different pieces of information center can exchange use each other, effectively simplify degree difficult in maintenance and reduce cost.In addition, the country that change data center is provided with or when regional, change even city's electrical specification is corresponding, after power distribution unit originally needs only the power supply input module that changes correspondence and/or imports the power distribution assembly, just can continue to use, do not need to select for use the power distribution unit of redesign, can reduce the change cost, can not cause the wasting of resources yet.
With manufacturer, the assembly of power distribution unit need not redesign, power distribution unit has the multiple pattern except power supply input module and input power distribution assembly, and other assembly is all identical, so the complexity of the whole manufacturing cost of power distribution unit and assembling can effectively reduce.And the power supply unit of power distribution unit can use the lower single-phase type of circuit complexity, 180～264 volts general-using type for example, and select the less power supply unit of input voltage range for use, but can make power distribution unit accept higher input voltage range, effectively to reduce cost and circuit complexity.
For reaching above-mentioned purpose, of the present invention one than the broad sense execution mode for a kind of three phase mains of many types of formula and power distribution unit of single phase poaer supply accepted is provided, in order to receive the electric energy of importing power supply and to be converted to out-put supply, can accept the three phase mains of many types of formula and the power distribution unit of single phase poaer supply comprises: the power supply input module, for detachable, extremely can accept the three phase mains of many types of formula and the power distribution unit of single phase poaer supply in order to the electric energy that transmits the input power supply; And input power distribution assembly, be connected in the power supply input module separably, in order to distribute annexation; Wherein, the side annexation each other of input power distribution assembly is △ type, Y type or type parallel with one another.
The three phase mains of many types of formula and the power distribution unit of single phase poaer supply accepted of the present invention, can be suitable for multiple city electrical specification widely, and change corresponding power supply input module or input power distribution assembly easily and apace according to corresponding city's electrical specification, can be so that the civil power (alternating current input power supplying) of the suitable multiple city of power distribution unit electrical specification.For the manufacturer of power distribution unit, the whole manufacturing cost of the power distribution unit of the three phase mains of accepting many types of formula of the present invention and single phase poaer supply and the complexity of assembling can effectively reduce.
