<p>PROBLEM TO BE SOLVED: To provide a gas-insulated switch which reduces the size of a gas- insulated switchgear as a whole, by utilizing dead spaces among phases effectively. SOLUTION: Racks 108a-108c are formed on sides opposite to bus-bar conductors 103a-103c in the peripheral parts of movable contacts 107a-107c. Pinions 112a-112c which engage with the racks 108 are provided, between the movable contacts 107a-107c and the conductors 115a-115c of movable contact portions. Containers 102a-102c are united and supported through the use of supporting containers 119a, 119b. The shafts of the pinions 112a-112c are linked on the same axis, through main shafts 114a-114c which pierce the supporting containers 119a-119b, joining rods 110a-110c-2 in addition, insulated rods 109a-109c, and joining rods 111a-111c-2. The main shaft 114c penetrates a rotation seal portion 116 and is led to the outside, and is linked to an operating apparatus 117.</p> |
