Abstract
The invention relates to an electrical isolating device (2) comprising a first connecting part (4a), a second connecting part (4b), an isolation point (6) which in the closed state forms a current path between the first and the second connecting parts (4a, 4b) and is located spatially between the connecting parts, wherein in the isolated state the isolation point (6) isolates the current path between the connecting parts (4a, 4b), and further comprising an auxiliary drive (8) which influences isolation of the isolation point (6). Particularly reliable isolation is ensured in that a flowable medium (10) driven by the auxiliary drive is disposed in such a way that it surrounds the isolation point (6) at least partially at least at the moment of isolation.
