ABSTRACT:
A gas-insulated power breaker (1) has encapsulation (2) which is filled with an inert gas. Live parts (10, 11, 12, 13) are arranged in the encapsulation (2). In order to prevent damage to the live parts (10, 11, 12, 13) during transportation, a transport support (17) is provided. In a secured position, the transport support (17) supports the live parts (10, 11, 12, 13) with respect to the encapsulation (2). It can be partially withdrawn and moved to an operating position, through a gastight aperture (22), without the inert gas having to be evacuated or the encapsulation (2) opened in this event. This allows the switch to be transported safely, prevents contamination of the interior (3) of the encapsulation (2), and avoids the need for costly emptying and refilling with inert gas.
