(??? ??????????? +25°?), % 80 Overview The control unit BU-3 serves as the control system of thyristor converters TFC intended for induction heating of metals in electrotechnology: melting, forging, stamping, tempering, annealing, etc. Appointment The control unit BU-3 is applicable for newly manufactured TFC, and for the replacement of old control systems of the 3rd and 4th generations. The control unit BU-3 is used for control, regulation, protection and diagnostic converters TFC series: The output frequency from 150Hz to 10kHz; Power from 40 to 800 kW; The control unit ECU 3 performs the following functions: - The formation of dual thyristor control pulse rectifier - The formation of the third control pulse for thyristors rectifier Management at angles ?> 60 ° (imitation works ventel zero). - Formation of the algorithm starting TFC. - The formation of a discharge pulse for the block start TFC. - Formation algorithm stops with TFC using an inverter mode rectifier. - Formation algorithm automatic restart (AR) TFC. - The formation of the control pulses of the inverter thyristors. The control algorithm minimizes the time to turn off the circuit of the inverter thyristors, which in turn minimizes the reactive power input and output TFC. - Implementing a closed loop control to stabilize the voltage at the load. As the control voltage output from the largest to the smallest value TPCH It works consistently in modes: The first mode - regulated inverter control angle, ?> ?min, steering angle rectifier is equal to the minimum value ? = ?min = 0 °. The second mode - regulated rectifier control angle, ?> ? min, steering angle inverter is equal to the minimum value ? = ?min, wherein achieved the minimum off time circuit of the inverter thyristors. The third mode - regulated inverter control angle, ?> ?min and steering angle rectifier ?> ? min to ensure continuity of current input and inverter output voltage stabilization. - It provides overcurrent protection and protection against overvoltage across the load. - Implementing a limit on the maximum current and maximum voltage at the load. - Implementing the protection thyristor rectifier and the inverter from overheating. Components and specifications Case dimensions BU-3, 165 mm x 219 x 62 The weight of the BU-3, 1.0 kg Set BU-3 Housing: Remote plastic screws for mounting PCBs PCB clearance 165.5h219mm The power supply system.
