Abstract
The invention relates to a universal vacuum interrupter (UVI) () for an air disconnect switch () comprising a rotatable actuating arm () arranged for engagement by a corresponding contact (), such as a roller, attached to the main blade () of an air disconnect switch (). In particular, the actuating arm () comprises two rods () extending next to each other and adapted for receiving the corresponding contact () of the main blade () between them. The two rods () are movable to alter the distance between them but are biased together by biasing means (), e.g. helical springs. As the corresponding contact () of a main blade () will be in engagement with both rods () during disconnection and reconnection of the air disconnect switch (), arcing is thereby prevented. Preferably, the two rods () of the UVI () are made of aluminium.
