PRODUCT DESCRIPTION The three phase controlled rectifier SZ6 unit is a power device for convert the three phase ac input voltage in a continuous rectifier output voltage with a three phase bridge thyristor rectifier and its internal control unit. The topology of the converter is a B6C type in the code designation according to IEC, the maximum dc link output voltage is 1.35 x Vac line (rms line-line), but is possible to modify the dc link output value controlling the 6 thyristor pulses. The internal control system can modify the thyristor pulse in order to have an output voltage time ramp depending on the selected value in the control side. All the feedback signal are internal connected to the interface boards and to the power section, the input command can be given from the external operator panel PU600 or from profibus connector. The input ac bars U, V, W of the AC/DC converter are available in the left part of the converter, DC link bars output are available in the bottom part of the device. The thyristor pulses are given by an internal electronic board with 6 isolated transformer pulse. Each thyristor is thermal protected by a thermal contact, in this way all the thermal contacts are series connected and a thermal contact status is used by the internal control for protect the semiconductors from overheating. Using the thermal contact the internal control system protect the semiconductors from an over temperature condition, when this output contact will be open, the control will disable the thyristor pulses and then open the main circuit breaker. In the power section, the power thyristors are series connected with a fast aR fuses for protect them from the shortcircuit at the dc link side. Each fast fuse is mounted with a contact status, all the fuse status are series connected and a fuse status is used by the control. When a fuse is broken the fuse output contact will be open and the control will disable the thyristor pulses and then open the main circuit breaker. The power thyristor modules are water cooled with a common heatsink. The cooling of the power semiconductors is performed with an internal water circuit with a 2 external quick water link of ½” diameter, inside the converter, an input and an output water collector perform all the water distribution to the heatsink.
