Abstract: In a state in which an operation screen for operating a frame in a frame page has been displayed, whether a change occurring to a frame in the page different from the currently displayed frame is a change arising from an operation satisfying a condition that is regarded to represent a user's explicit intention to view the different frame or not is judged. If the change is judged by the judgment to be a change arising from an operation satisfying the condition, the display is shifted to a screen showing the page in whole display and notifying the user of the frame to which the change has occurred.

Abstract: In a gas-insulated switching device capable of reducing the physical installation space while suppressing the installation height of the device, busbar connecting lines are disposed perpendicularly to and between as pair of main busbars to connect the main busbars. Three sets (one set per phase) of three serially connected horizontal broker units are placed in parallel, and each of the main busbars has three busbar units along a portion extending vertically from the end of the busbar connecting line.

Abstract: In order to shorten the length of connection buses and reduce a cost, in the present invention, a plurality of T-branched circuit breaker units 12 are arranged in a direction perpendicular to the T-branch direction, and the plurality of circuit breaker units 12 are connected by first connection bus units 14 and second connection bus units 15 in series alternately in a rectangular wave shape on a horizontal plane of approximately the same height as the T-branch portions of the circuit breaker units 12. Thereby, first connection buses 5 and second connection buses 6 are stretched around on the horizontal plane of the same height as the T-branch portions of the circuit breaker units 12, but not stretched around in an up and down direction. Therefore, the length of the connection buses can be reduced, and the cost also can be reduced.
