Abstract
A disconnector device for a surge arrester is provided. The disconnector device includes: a housing encompassing a cavity; a disconnector provided inside the cavity, having a first terminal connectable to the surge arrester, a second terminal connectable to ground, a movable member provided at the second terminal and being fitted to the cross section of the cavity, and a disconnector cartridge. The member is movably arranged such in the housing that once the disconnector operates, the movable member is propelled inside the cavity towards an end of the cavity. The housing has ventilation openings connecting the cavity to an outside of the disconnector device for releasing gases from the operating disconnector cartridge. These ventilation openings are dimensioned such that no particles of harmful size that are potentially capable of igniting a fire can pass the ventilation openings.
