摘要
An arrester for a gas insulated switchgear device includes a closed container filled with an insulating gas; a columnar piled body formed by piling up a plurality of zinc oxide resistance elements between a high voltage side terminal and a grounding side terminal disposed in the closed container; a plurality of potential equalizing rings electrically and mechanically connected to the high voltage side terminal of the columnar piled body, the potential equalizing rings being disposed in a discrete manner along the piling up direction of the zinc oxide resistance elements with a predetermined spacing distance while surrounding the outer circumference of the columnar piled body; and an intermediate electrode disposed around the columnar piled body at a position facing the potential equalizing ring located nearest to the grounding side terminal among the potential equalizing rings.
