POWER DISTRIBUTION STRUCTURE FOR ELECTRICAL EQUIPMENT STORAGE RACK

摘要

PROBLEM TO BE SOLVED: To provide a power distribution structure for an electrical equipment storage rack for dissolving that an influence of an electric abnormality and short-circuit has on the other distribution system to minimize an electric trouble even when the electric abnormality and short-circuit are generated at a part of a power distribution system.

SOLUTION: A power distribution structure supplies a plurality of power sources with different voltages to a rack body 3 which stores electric equipment 2. The power distribution structure is made into independent structure by being divided by power cables 20, 21 with different voltage; a plurality of main distribution outlets 22; sub-distribution outlets 23; a plurality of high-voltage power supply systems 24; and a plurality of low-voltage power supply systems 25, etc. Furthermore, the high-voltage power supply systems 24 are constituted by electrically connecting a plurality of high-voltage outlet bars 45. The respective low-voltage power supply systems 25 are constituted of low-voltage outlet bars 55. The main distribution outlets 22 and the sub-distribution outlets 23 are integrally arranged on an attachment wall 15 on the top surface of the rack body 3 at a state that they are exposed to the outer surface the rack body 3.
