Rectifier for electrochemical treatment "VIRE-5000”
Pulse adjustable rectifier for electrochemical treatment “VIRE-5000” is made for power supply of plants of electrochemical treatment of heat-resistant and titanium materials by direct and pulse current in conditions of mild and cold climates.
Principle of operation
Power three-phase transformer is made with a water-cooled secondary windings. Power adjustable rectifier with thyristors in a three-phase bridge circuit performs rectification and voltage regulation on the secondary side of the power transformer. At the output of the bridge controlled rectifier is connected LC filter. Power transistor switch is made on the basis on IGBT transistors and is made to generate a pulsed output voltage.
Interruption of current in pulsed mode is performed with variable frequency and pulse duration, set from the control panel of the rectifier or external control system. Parameters of the pulse mode are displayed by a digital indicator.
Repetition frequency and pulse duration of the output voltage are set from the control panel of the rectifier or from the signals of external control panel and displayed by a digital indicator on the control panel.
