...Heater for snow melting. Amendment August 20, 1982 The scope of claims for utility model registration is amended as follows. O Utility Model Registration Claims (1) Two busbar sides each connecting multiple gas-insulated switchgear units consisting of circuit breakers, disconnectors, connecting circuits, etc. to an air-insulated double busbar. In a gas-insulated switchgear in which a bushing is shared by at least two switchgear units, a busbar-side disconnector of two switchgear units that connects each of the two shared busbar-side bushings; Components configured on one side are arranged on two straight lines that are parallel in plan, and the operation mechanism boxes, etc. of the two switchgear units that share the bus line side bushing are placed inside the two straight lines. A gas insulated switchgear characterized in that the two straight lines are arranged facing each other and at least the inside of the two straight lines is at least partially covered with a protective cover. (2) The gas insulated switchgear according to claim 1, wherein the protective cover has a cross-sectional shape that includes a roof portion and one side wall portion that are lower than the breaker. 1.・. (3) The gas insulated switchgear according to claim 1, wherein a snow melting heater is provided inside the top of the gable-shaped roof portion. (4) The gas insulated switchgear according to claim 1, wherein the ceiling height of the protective cover is 2 m or more. - (5) The gas insulated switchgear according to claim 1, wherein the side wall of the protective cover has the shape of a sliding shutter.
