Thyristor switch - with three thyristors
The thyristor switch thyroswitch 3P combines functional features already distinguished in the thyroswitch 2P: fast and wear and tear-free connecting and disconnecting of capacitors, unlimited switch frequency with low switch delay and compensation almost in real-time. The device generates no operating noise whatsoever and has a compact construction ready for connection.
thyroswitch 3P has three thyristors, each of which can switch alone or together. If the switch-on procedure is activated via a reactive power controller or a control, there is a voltage comparison between the capacitor voltage and the mains voltage. If there is a slight difference, the stage is switched on.
Highlights
- Unlimited switching frequency without load on capacitors
- No peak inrush current when switching on capacitors
- Low switching delay
- Compensation almost in real-time
- No operating noise
