Thyristor switch for reactive power compensation

thyroswitch

Reactive power compensation components
VO2 3217VO2 3214

The thyroswitch thyristor switches enable reactive current compensation almost in real time.

Due to its unlimited switching frequency and minimal switching delay, the thyroswitch switches choked and unchoked capacitors on and off quickly and wear-free. When the capacitors are switched on in a controlled manner, no switch-on current peaks occur and the switching contacts do not wear out. This reduces the load on the capacitors, which in turn leads to a longer service life. In addition, the device operates silently and is characterized by its compact, ready-to-connect design. This results in significant advantages over conventional standard contactors.

The thyristor switch is available in both 2-phase and 3-phase versions. The thyroswitch is controlled via the multicomp reactive power controller or directly via the machine controller. If the switch-on process is activated via a reactive power controller or a control unit, a voltage comparison is made between the capacitor voltage and the mains voltage. If the difference is small, the stage is switched on.

The 2-phase thyristor switch thyroswitch 2P has two thyristors that switch phases L1 and L3. Phase L2 is connected but not switched.

The 3-phase thyristor switch thyroswitch 3P has three thyristors, each of which can switch individually or together.
