The invention relates to a device for containing a gas leak in a region with a change in diameter in a circular cross-section pipe of a gas insulation switchgear or a gas insulation high voltage circuit-breaker. According to the invention, such a device comprises : a first diameter-transition ring; a second diameter-transition ring having an outer diameter substantially identical to that of the first ring; cowling means for at least partially surrounding said region with a change in outer diameter, configured to be sealingly mounted on the outer annular profile of the first transition ring and on the outer annular profile of the second transition ring; and means for sealing the mounting regions.

In a multi-busbar system gas insulated switchgear, a power transmission/reception line unit (I) is constituted by providing a plurality of branch lead-out ports at regular intervals (interval H) along a vertical direction on the lateral side of a tank of a vertical-type circuit breaker, connecting a line-side device to the uppermost branch lead-out port, connecting the busbar-side devices to the lower branch lead-out ports, and arranging the line-side device to face the circuit breaker while placing multiple busbars therebetween. In a busbar link line unit (III), the tank length of a vertical-type circuit breaker is shorter than the tank length of the circuit breaker by the interval H, and an interval between a plurality of branch lead-out ports for busbar-side-device connection that are provided on the later side of the tank of the circuit breaker along a vertical direction is also the interval H.
