Abstract

L'INVENTION S'APPLIQUE A LA PROTECTION DE LIGNES AERIENNES COMPRENANT AU MOINS DEUX CHAINES D'ISOLATEURS 1 POURVUES D'ELEMENTS DE PROTECTION 5 CONTRE LES ARCS ELECTRIQUES, LES CHAINES ETANT SUSPENDUES PAR LEUR EXTREMITE SUPERIEURE A UN SUPPORT. LEUR EXTREMITE INFERIEURE EST ARTICULEE A UNE ENTRETOISE METALLIQUE 2. LES PINCES 9 DESTINEES AUX LIGNES AERIENNES SONT DISPOSEES SUR LE COTE DE L'ENTRETOISE SITUE A L'OPPOSE DES CHAINES D'ISOLATEURS. LE DISPOSITIF DE PROTECTION DOIT PERMETTRE DE REALISER UNE ZONE D'INTENSITE DE CHAMP PLUS FAIBLE DANS L'ENVIRONNEMENT DES PINCES A CABLE ET DES AUTRES ELEMENTS PORTEURS. DANS CE BUT, LE DISPOSITIF DE PROTECTION COMPREND UN ANNEAU DE GARDE 10 FIXE AUX DISPOSITIFS PORTEURS 7 QUI RELIENT LES PINCES 9 A L'ENTRE-TOISE 2. APPLICATION AUX LIGNES AERIENNES A HAUTE ET TRES HAUTE TENSION.
