SPACE SAVING TYPE CUBICLE POWER RECEIVING AND TRANSFORMING FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a space saving type cubicle power receiving and transforming facility that supplies a plurality of transformed voltages and, at the same time, the installation space of which can be reduced largely from that of the conventional facility.;SOLUTION: This cubicle type power receiving and transforming facility is composed of a transformer and a cubicle case housing the transformer. The three-phase three-leg core of the transformer has three legs. Two of the three legs are respectively wound with three-phase primary and secondary windings and the remaining one of the legs is wound with a single-phase tertiary winding. In addition, intermediate secondary terminals are respectively connected to the intermediate sections of the three-phase secondary windings. Of these windings, a single-phase transforming section and two three-phase transforming sections which are supplied with different voltages are formed around the three- phase three-leg core.;COPYRIGHT: (C)2003,JPO
