Background technology
Further accurate complicated along with the modern railway transportation communication equipment often needs a plurality of equipment to work simultaneously, and its mutually between communication closely link to each other, therefore these device designs that closely link to each other can be become the form of cluster in the design.Rack also can comprise a plurality of equipment, such as power supply unit as a minimum unit module of cluster form.As everyone knows, the running of equipment be unable to do without the support of electric power, specified, stable electric current is provided therefore how for a plurality of equipment, just be unable to do without power supply unit.Owing to multiple demands such as the power supply that will satisfy electromagnetic compatibility, multiple different magnitudes of voltage, power source diverter, power supply signal controls, so that comprised a large amount of power supply apparatus facilities in the existing power supply unit, this just causes following defective yet at present:
(1) because power supply apparatus is installed on interior of equipment cabinet everywhere, cause the cable wiring complexity various, scattered without chapter, therefore be not easy to the installation and maintenance of equipment.
(2) because the complexity of cable wiring and unordered, so that dirty line, clean line mix, the multiple cable such as holding wire, power line intersects or is parallel, so the Electro Magnetic Compatibility of rack integral body is poor, the equipment cable life-span is short.
Be in the state without the housing protection when (3) putting owing to various power supply apparatus, and electric current is supply current, therefore unshielded equipment cause potential safety hazard, the poor stability to the personnel of the equipment in the rack and operation.
(4) since power supply apparatus be connected with cable connection, arrange comparatively complicated, this cable wiring mode has larger randomness simultaneously, therefore on the interior of equipment cabinet structural design, can not form stable design, and be unfavorable for cost accounting, more the equipment aesthetic property be had larger impact.
