Product Overview
Altae tensio aeris rupturae commutatores et eorum combinata apparatus electrica sunt indoor alta tensio apparatu pro AC 12kV, 50Hz. Haec commutator rupturae praebet alta specifica technica parameter et fida actionem. Basis formae mechanismi operationis est manuale spring-energia-storaginis typus, et potest etiam adhiberi electromagneti spring operans mechanismus. Super pneumatico arc-extinguendo principio, potest plures vicibus interrumpere absque substitutione arc-extinguendi tubi.
Commutator altae tensionis potest claudere, portare et aperire oneris currentes sub normalibus circuiti conditionibus, et habet facultatem claudendi brevis circuitus currentes et aperiendi brevis circuitus currentes intra specie definitum breve tempus.
Commutatores rupturae posse adhiberi cum terre interruptores. Terre interruptor habet idem brevis circuitus faciens capacitas sicut commutator rupturae, tamquam et dynamica et calor stabilis capacitas, et habet strictam mechanicam interlock cum commutatore rupturae, assecurans quod misoperation sit impossibile in structura.
Key Features
Cum FKN12 - 12 commutator rupturae adhibetur cum alta tensio limitans fusus (cum percussore) ad formandum commutator rupturae-fusus combinationem, servit ut supercarga et brevis circuitus protectio pro oneribus (sicut potentia transformatoribus). Cum una vel plures phase fusus exardescunt, tres phases commutator rupturae automaticiter aperiunt.
Commutator altae tensionis aptus est ad installationem in ring-main unit switch cabinets et alii species switch cabinets pro recipiendo et distribuendo electricam energiam.
