PROBLEM TO BE SOLVED: To obtain a mounting device which is not damaged by a high-temperature and high-pressure gas released when a miniaturized cabinet is abnormal by a method wherein an insulating plate is arranged between one pair of frame bodies which support a gas-insulated switch provided with a pressure release part. SOLUTION: One side 9a at one pair of frame bodies 9 is fixed, by a U-shaped bolt 10, to a horizontan angle inside a cabinet, and a pressure release part at a gas- insulated switch is brought close to the inside of the cabinet so as to be supported by the other side 9b at the frame body 9. An insulating plate 11 which is arranged in a position corresponding to the pressure release part and which is connected to one side 9a at both frame bodies is installed between the pressure release part and the wall surface of the cabinet 12. As a result, when, e.g. an internal short-circuit accident is generated inside the airtight container of the gas-insulated switch which is housed in the cabinet, a pressure inside the container is raised quickly, the pressure release part is operated when the pressure exceeds a prescribed pressure, and a gas inside the container is spouted to the outside. The spouted high-temperature and high- pressure gas is received by the insulating plate 11. Thereby, it is possible to prevent the wall surface of the cabinet from being damaged. |
