<p>Protection arrangement against a solicitation by suppression of the encapsulation (6), in switching devices encapsulated and insulated by pressure gas, distributed within individual sealed compartments. The arc is short-circuited for extinction thereof by means of a transmitter the signal of which is transmitted by an amplifier (4) to an extinction device. To detect the expansion of a capsule resulting from a pressure pulse, at least one expansion detector is arranged on the outer wall of the capsule for each sealed compartment. </p> |
