6.1 WATER COOLED BRIDGE RECTIFIER
The medium voltage cables for the input rectifier supply come from the input transformer secondary windings. The transformer configuration
and the number of cables depend on the rectifier number of pulses:
12 pulses 6 cables.
18 pulses 9 cables.
24 pulses 12 cables.
36 pulses 18 cables.
Considering the standard rectifier version (18 pulses) the secondary winding voltage depends on the motor nominal voltage, being 1.5 kV for
motors of 4160 V rated voltage and 1.2 kV for motors of 3300 V rated voltage. The 9 cables enter the rectifier cabinet at the top or at the
bottom and are connected directly to terminals mounted on the rectifier module copper bars.
