Abstract

Oppfinnelsen angår en høyspent strømbryter som omfatter i serie, minst et begrensende sikringselement og minst et utblåsningssikringselement (9) innbefattende en elektrisk ledende tråd (7) omhyllet av en elektrisk isolerende hylse (8). Rommet (E) som danner en spesifikk klaring mellom trådens (7) ytre overflate (7b) og hylsens (8) indre overflate (8b) blir fylt med et elektrisk isolerende fluid (7). Det elektrisk isolerende fluidet muliggjør å redusere, til og med kansellere, risikoen for utblåsning mellom ledningstråden (7) og den isolerende hylsen (8).The invention relates to a high voltage circuit breaker comprising in series, at least one limiting fuse element and at least one blowout fuse element (9) including an electrically conducting wire (7) enclosed by an electrically insulating sleeve (8). The space (E) which forms a specific clearance between the outer surface (7b) of the thread (7) and the inner surface (8b) of the sleeve (8) is filled with an electrically insulating fluid (7). The electrically insulating fluid makes it possible to reduce, even cancel, the risk of blowout between the conductor wire (7) and the insulating sleeve (8).
