PURPOSE:To reduce the entire facility disposition of an AC/DC converter and to conveniently maintain and inspect the AC/DC converter by installing both polarity conversion units next to an AC bus, mounting conversion transformers in both conversion units, and further installing accessories next to the both convertion units. CONSTITUTION:An AC bus AC1 is disposed in the site of an AC/DC converter, positive and negative polarity conversion units IN1, IN2 are aligned and installed at the insulating distance l1 next to the bus. At this time, conversion transformers TR1b, TR1a, TR2a, TR2b are mounted in the interval l2 between the circuits IN1 and IN2. DC reactors DCR1, DCR2 and DC breakers DCB1, DCB2 are respectively mounted next to the units IN1, IN2, and clean towers Cl1, Cl2 are installed in the vacant space. Neutral wire N is arranged from the breakers DCB1, DCB2 directly to the buses DC1, DC2. |
