<p>PROBLEM TO BE SOLVED: To reduce the disposition space of a gas-insulated switching device and improve its operation, maintenance and inspection qualities, by providing collectively on its front side the operational means for operating disconnectors, etc., stored in the respective tanks, etc., of its transmitting/receiving units. SOLUTION: In a gas-insulated switching device, on the front side of a receiving unit 1, operational means 19-21 stored in a container used both as a storage and as a cover are provided in a line, vertically to provide an operational means 22 on the lateral side of the means 21, and on the front side of a transformer primary unit 2, operational means 35, 36 are provided in a horizontal direction. Further, opening a front door 40 of the gas-insulated switching device, the operational means 20, 21, 22, 19 are operated in order to operate both a disconnector DS1 and a ground switch ES1 in a tank 5, a ground switch ES2 in a tank 6 and a disconnector DS2 in a duct line 7. Subsequently, the operational means 36, 35 on the front of the device are operate, in order to operate both a ground switch ES3 in a tank 10 and a disconnector DS3 in a duct line 11 of the transformer primary unit 2. As a result, the installation space of the device can be reduced and the operation, maintenance and inspection qualities of the disconnectors, etc., can also be improved.</p> |
