いる。In recent years, variable speed operation using an AC motor using a rotational voltage variable frequency power supply device tC (hereinafter referred to as a variable power supply device) has become popular. For the purpose of reducing harmonics, a two-winding, six-phase AC motor in which the phases of the main circuit windings of the three-phase or current motor are shifted by 30 degrees from each other is used. A variable speed drive system using a 12-pulse variable power supply is used. There is. On the other hand, when an important load is driven by an AC electric ML2 using a Machhi power supply system rIIL, if the variable power supply fails, the 11L motor is disconnected from the variable power supply and the commercial power supply is switched off. It is generally done to perform the entire backup protection operation by turning on the power.

である。Since the main circuit windings of a two-winding, six-phase motor are out of phase, it is impossible to operate them using the same commercial power source. ＃The phase of the secondary circuit is shifted by 30 degrees for the purpose of reducing harmonics 2
Next, install a 2-winding hydraulic pressure generator, and in the event of a failure of the 12-pulse variable power supply, disconnect the 2-winding 6-phase electric power a from the variable power supply, then connect the secondary 2-winding transformer. Use a commercial power supply with a 30° phase difference between the two windings of a 2-winding, 6-phase motor! This is a drive device that enables back-up protection operation by supplying.
