PURPOSE:To make the high-power and high-frequency transmission possible, by storing a switch in an airtight tank in which an insulating gas is sealed and providing a connecting port to pierce the wall of the tank with airtightness. CONSTITUTION:Three connecting ports 12 are projected from the circumferential face part of a contactless switch 11 having a round housing, and flanges 16 are provided at tips of connecting ports 12, and coaxial feeders 13 (13a-13c) are connected to them. A revolving shaft is provided freely rotatably in the center of the housing, and a disc consisting of an insulating material provided with a movable coupling conductor is attached. An internal conductor is provided in each of connecting ports 12, and its end part is projected into the housing, and a fixed coupling conductor is attached. The switch 11 is provided in a closed tank 10, and connecting ports 12 are fixed to the closed tank 10 by welding, and the rotation shaft is subjected to gas sealing. An insulating gas such as an SF6 is pressurized and sealed in the closed tank 10. |
