Abstract (en)
A medium voltage gas insulated switch (100) comprising a first electric contact (102); and a second electric contact (104) that is moveable with respect to the first electric contact and a plurality (200) of splitter plates (200-1, 200-2, ...) configured to interrupt an electric arc (110) between the first electric contact (102) and the second electric contact (104) during the switching operation of the switch; a splitter plate holder (510) that holds the plurality of splitter plates; some of which are ferromagnetic; exterior side walls (500) of the splitter plate holder (510); wherein the splitter plate holder electrically insulates different splitter plates in the plurality of splitter plates; and wherein the exterior side walls (500) of the splitter plate holder (510) are configured to block a flow of gas perpendicular to the side walls and to prevent a bridging of the electric arc (110) around splitter plates (200-1, 200-2, ...) in the plurality (200) of splitter plates;and wherein the exterior side walls (500) are further configured to facilitate an evacuation of a hot gas by directing a flow of the hot gas in a direction parallel to the exterior side walls.
