The role of vacuum contactor in reactive power compensation system
The composition of the reactive power compensation system is from top to bottom:
Traditional reactive power compensation is:
Blade fuse switch - arrester - current transformer - fuse - contactor - thermal relay - capacitor.
The new reactive power compensation system is:
Blade fuse switch-surge arrester-current transformer-intelligent capacitor
The function of the contactor is to conduct the capacitor, which acts as a switch.
In the traditional reactive power compensation system, the capacitor cutting process will produce between 20-100 times the inrush current, the contactor in the input will produce a shock, in the removal of the time will produce an arc, burned contactor. Vacuum contactor is generally strong breaking capacity, contact does not oxidize, arc is not exposed, safe and reliable.
