THREE-PHASE THREE-WIRE TO SINGLE-PHASE THREE-WIRE SWITCHING TYPE POWER GENERATING FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a three-phase three-wire to single-phase three-wire switching-type power generating facility capable of switching three-phase three-wire and single-phase three-wire by one switching operation using only a switching unit.;SOLUTION: With the configuration of the switching unit SWU and a wiring circuit DC, a parallel star connection which is constituted by connecting U-phase magneto coil U and u-phase magneto coil u in parallel, connecting V-phase magneto coil V and v-phase magneto coil v in parallel, and connecting W-phase magneto coil W and w-phase magneto coil w in parallel, is connected to the first to third output lines OL1 to OL3 when a switching operation part SH is in a first switching position P1. When the switching operation part SH is in a second switching position P2, a double delta connection provided with a first delta connection consisting of U-phase magneto coil U, v-phase magneto coil v, and w-phase magneto coil w and a second delta connection consisting of u-phase magneto coil u, V-phase magneto coil V, and W-phase magneto coil W, is connected to the first to third output lines OL1 to OL3.;COPYRIGHT: (C)2010,JPO&INPIT
