Thyristor capacitor banks, upgraded

ust-kond-niz-napr-006Compared to banks with contactors - capacitor banks with thyristor control UKMT have a very high speed of switching because since there is no need in a delay of actuation for capacitor discharge time.
UKMT application is most popular in networks with a quick-changing load: stamping equipment, welding equipment, lifting and carrying mechanisms, pumps and compressors with varying productivity, etc.

Key point of capacitor banks with thyristor switches operation is based on the fact that commutation operations happen in the moment of voltage passing through zero, i.e. when voltages of capacitor and network are equal. Thanks to this, peak current surges are absent at the capacitors in the switching moment and capacitors life period become longer.

Due to the absence of moving mechanical contacts the thyristor switches have a big resource and are almost noiseless during operation.

Thyristor capacitor banks have quick-operating fuses which protect thyristors from current overloads.
Also there is thyristors protection from overvoltage in a network.
