Factory of HYTSC High Voltage Dynamic Reactive Power Compensation Devices

working principle

The high-voltage TSC dynamic reactive power compensation device is composed of optical fiber trigger control system, valve control system, reactor, protection unit and other units. The control system is monitored by a microcomputer in real time and intelligently adjusted. The capacitor bank is switched by thyristors. When the reactive power 1 current detected by the controller exceeds the set value, it will automatically determine the number of capacitor banks to be switched on, and control the regulator to output a trigger signal to the specified thyristor to turn on the capacitor bank. put into service. When the load reactive current value is lower than the set value, the controller will give a control signal, and the trigger will stop sending the trigger signal and the capacitor bank will quit working. The above working conditions are fully automatic to ensure that there is no impact, no surge, and no transition process when switching capacitors.
