THYRICON 1(3)P3.40/80R microcontroller based reactor switching thyristor modules are designed to switch inductive loads where inductive reactive power is needed, without affecting the power quality.
Oppose to capacitor switching, switching of the reactors without creating inrush current, is done at the instant of 90o phase of the voltage across the reactor. The reactors being saturated and drawing a high amount of initial DC current is prevented by this method. At the instant of the switching, absence of DC inrush currents, prevents voltage transient. Similarly, in turn off, the natural commutation of the thyristors prevents the voltage spikes on the switching element.In this way, the problems that may arise due to reactive power compensation switching is eliminated in the plants where CNC / PLC and sensitive equipment such as computers exists.
ThyriCon offers an effective solution for the reactive power compensation of the loads with wide range and rapidly changing reactive power requirements such as punto welding machines, cranes and arc furnaces. Thanks to the capability of switching in a short time less than 20 msec, ThyriCon provides good results in systems where the performance of traditional reactive power compensation systems are not sufficient.
