Abstract
A metal-clad electric switch having gas insulation and a metal case comprises a case whose inside volume is subdivided into at least two compartments separated by a leakproof partition. A first disconnector is disposed in one of the compartments and comprises a first blade co-operating with a first connection terminal. A second disconnector is placed adjacent to the first disconnector in the other compartment and comprises a second blade co-operating with a second connection terminal. The blades are secured to a common rotary shaft passing in leakproof manner through the partition and providing electrical conduction between the blades.
Claims6
A metal-clad electric switch having gas insulation and a metal case (1), the switch comprising at least first and second load disconnectors (4, 5) placed adjacent to each other inside the case, the first disconnector comprising a rotary blade (4A) co-operating with a first connection terminal (4B), the second disconnector comprising a rotary blade (5A) co-operating with a second connection terminal (5B), said first and second blades being secured to a common rotary shaft (7) providing electrical conduction between said blades, the switch being characterized in that the case has an inside volume which is subdivided into at least two compartments (1A, 1B, 1C) separated in pairs by respective leakproof partitions (2, 3), in that the first disconnector is placed in a first of said compartments and the second disconnector is placed in a second of said compartments, and in that the rotary shaft (7) common to said blades passes in leakproof manner through the partition (3) separating the first and second compartments.
