Abstract
L'invenzione si riferisce ad un interruttore ad alta tensione isolato a gas comprendente un primo compartimento stagno riempito di gas isolante sotto pressione ed a rigidità dielettrica elevata, nel caso di specie dell'esafluoruro di zolfo SF6, e racchiudente almeno un polo di interruzione avente una coppia di contatti separabili, un dispositivo di estinzione dell'arco reso attivo all'atto della separazione dei contatti ed un albero di azionamento accoppiato ad un meccanismo di apertura e di chiusura. L'interruttore secondo l'invenzione è caratterizzato dal fatto che il meccanismo di comando è alloggiato in un carter stagno delimitante un secondo compartimento giustapposto al primo compartimento, e comprende un martinetto pneumatico il pistone mobile del quale è azionalo dal gas SF6 sotto pressione contenuto nel primo compartimento durante ciascuna manovra di chiusura o di apertura, il secondo compartimento a bassa pressione svolgendo il compito di volume di espansione del gas spinto fuori dal martinetto alla fine della corsa di chiusura o di apertura del pistone.
