4.Training bench for commanded and non commanded stabilizers min power 0.5 kW The bench must allow the study of : - study of single phase non commanded stabilization 1 diode simple alternation stabilization Double alternation with transformer with middle point and 2 diodes Double alternation with 4 diodes bridge, PD2 - study of commanded single phase stabilizer 1 thyristor simple alternation stabilization Double alternation with transformer with middle point and 2 thyristors Double alternation with 4 thyristor - study of 3ph non commanded thyristor Simple alternation stabilization by 3 diodes common cathode Simple alternation stabilization by 3 diodes common anode Double alternation stabilization by 6 diodes - study of 3ph commanded stabilizer
Simple alternation stabilization by 3 thyristors common cathode Simple alternation stabilization by 3 thyristors common anode Double alternation stabilization by 6 thyristors - study of single phase mixed stabilizers Mixed double alternation and symmetrical with 2 diodes and 2 thyristors Mixed double alternation and asymmetrical with 2 diodes and 2 thyristors - study of 3 phase mixed stabilizers Mixed double alternation and symmetrical with 3 diodes and 3 thyristors Mixed double alternation and asymmetrical with 3 diodes and 3 thyristors The bench must be delivered totally equipped and functional with - universal module containing the power components (diodes and thyristors) and protection circuits against overloads and short circuits. This module serve to study different stabilizers cabling simply by choosing the corresponding mask - necessary power supplies (transformer with single phase outputs and 3 phase outputs with at least 2 voltage levels) - thyristors command unit ( for commanded stabilization).
5.The bench must be delivered totally equipped with: - shunts for current measuring - necessary loads: resistive, inductive, capacitive which are variable and with DC motor by shunt excitation. All loads must have the same power as the bench. - all necessary connection accessories
