Abstract
A gas insulated switch-gear apparatus having first and second base planes is disclosed. Arranged on the first and second base planes are feeder switching apparatus comprising gas filled circuit breakers and first and second gas insulated disconnecting switches at opposite sides of each of the gas filled circuit breakers. Gas insulated busbar devices are arranged to be horizontally spaced from the feeder switching apparatus. On the first and second base planes, the first gas insulated disconnecting switches are connected to the gas insulated busbar devices while the second gas insulated disconnecting switches are connected to bushings. Axial lines of the feeder switching apparatus along which the first and second gas insulated disconnecting switches are arranged traverse axial lines of the gas insulated busbar devices. The axial lines of the gas insulated busbar devices arranged on the first and second base planes lie in a common vertical plane containing the axial lines and lie in the base planes. A gas insulated connecting busbar device for interconnecting the gas insulated busbar devices arranged on the first and second base planes is arranged in the common vertical plane such that an axial line thereof traverses the axial lines of the gas insulated busbar devices.
