Abstract
An earthquake protection device is provided for a gas-insulated switching installation. The gas insulated switching installation has at least one busbar, at least two switch panels, each mounted on a supporting frame, and an arrangement for connecting the supporting frames to a foundation such that at least one of the supporting frames is displaceable at least in a direction of the busbar axis, and extends in a direction of a busbar axis. The at least one displaceable supporting frame is provided with at least one shock absorber, the shock absorber having an active axis in a plane of the supporting frames, the active axis running proximate a center of gravity of at least one of the switch panels.

An earthquake protection device for a gas-insulated switching installation, comprising:
- a gas-insulated switching installation having at least one busbar the busbar having a busbar axis, the switching installation having at least two switch panels and at least two supporting frames, each of the switch panels being mounted on a respective one of the supporting frames;
- means for connecting the supporting frames to a foundation such that one or more supporting frames are displaceable supporting frames, the displaceable supporting frames being displaceable relative to at least part of the connecting means at least in a direction of the busbar axis;
- at least one shock absorber associated with the displaceable supporting frames, the shock absorber having an active axis lying in a plane of the supporting frames;
- and
- the active axis extending proximate a center of gravity of at least one of the switch panels.
