Basic Info.
Product Description
General
ZVV vacuum on-load tap-changer is a composite on-load tap-changer developed by vacuum arc
extinguishing technology. The vacuum interrupter is used to replace the traditional copper-tungsten
contacts to break the current. Since the arc extinguishing is completed in the vacuum arc extinguishing
chamber, there is no direct contact between the arc and the transformer oil, and the transformer oil
does not produce carbonization and solid particles in the on-load tap changer, which reduces the
operating cost of the switch and prolongs the maintenance period of the switch.
The ZVV vacuum on-load tap changer is suitable for the highest working voltage 40.5kV, 72.5kV; the
maximum rated through current 350A, 500A; the rated frequency of 50Hz or 60Hz power transformers
can be achieved by changing the tap position of the transformer voltage regulating winding under load
Purpose of pressure regulation.
