Abstract

L'interruttore per bobine di reattanza è previsto per l'inserimento e il disinserimento di una bobina di reattanza inserita in una rete elettrica polifase ad alta tensione. Esso presenta poli di commutazione (3) disposti a seconda delle fasi fra la bobina di reattanza (2) e una parte della rete contenente per esempio una linea (1) ad alta tensione. Questi poli di commutazione (3) contengono ciascuno quanto meno due camere di commutazione (11, 12; 13, 14) collegate in serie, in parallelo alle quali sono collegati almeno due varistori (15, 16; 18, 19) collegati in serie.Questo interruttore per bobine di reattanza deve poter disinserire senza problemi corti circuiti che si manifestano fra l'interruttore e la bobina di reattanza (2).Ciò si ottiene grazie al fatto che i varistori (15, 16, 17,
