GAS INSULATED SWITCH GEAR

PROBLEM TO BE SOLVED: To provide a gas insulated switch gear having a linear seal structure capable of preventing deterioration of air-tight performance due to operation of an opening/closing part without giving influence to assembling work. SOLUTION: A fixed guide 2 is provided to be inserted from the inside of a sealed container 11 to the outside of the sealed container 11 in a cylindrical part 2b thereof and air-tightly connected to the sealed container 11 in an end plate 2a thereof. A air-tight packing 4 forming an air-tight part of the linear seal structure between an operation rod 1 is arranged in the end plate 2a of the fixed guide 2. A movable guide 3 to be guided by the cylindrical part 2b is provided in the operation rod 1 in a part positioned outside the sealed container 11 more than the air-tight packing 4.
