Electric power t71 generated by the main generator 1 is stepped down by the in-station transformer 3a E1. .Connect to the high voltage bus 5a.
The variable frequency power supply unit 115 of the X-type motor is connected, and the variable frequency power output is supplied to the furnace recirculation pump motor 7 through the variable frequency output disconnection line 16, while the high voltage is supplied through the in-house transformer 3hl. Full power is supplied to the bus 51), and seven furnace recirculation Bonzo motors are driven through the thyristor-type Machikasa wave power supply t6%.
