Abstract

Вакуумний вимикач (700) містить: електродний вузол (724), що містить електричний контакт; ізолятор (515), що містить електроізоляційний матеріал, розташований в основному навколо електродного вузла; і екран (716), розташований між ізолятором (515) і електродним вузлом (724), який має конфігурацію, що запобігає осадженню плазми дуги від електричного контакту електродного вузла принаймні на частині поверхні ізолятора (515). Екран (716), який містить перший сегмент, виконаний таким чином, що він забезпечує розміщення екрана співвісно з ізолятором (515). Другий сегмент, який виходить з ізолятора (515), і кінцевий сегмент, який проходить у напрямку до ізолятора (515) і містить край екрана (716). Кінцевий сегмент не проходить у напрямку до другого сегмента, в якому осьова відстань між першим сегментом і кінцевим сегментом є більшою, ніж осьова відстань між першим сегментом і другим сегментом, та в якому лінія, що є перпендикулярною поздовжній осі електродного вузла (724) та проходить крізь неї, проходить крізь край і перетинає екран (716) лише у двох місцях його поперечного перерізу.
