Abstract:
1. Electrical disconnecting device comprising: a first connecting part; a second connecting part; a disconnection point which in the closed state forms a current path between the first and the second connecting parts and is located spatially between the connecting parts, wherein in the isolated state the disconnection point isolates the current path between the connecting parts; an auxiliary drive which influences isolation of the disconnection point, wherein a flowable medium driven by the auxiliary drive is disposed in such a way that it is in direct contact with the disconnection point at least at the moment of mechanical disconnection of the first and the second connecting parts from one another; a guide housing having a space disposed between the auxiliary drive and the disconnection point and/or on a side of the disconnection point turned away from the auxiliary drive; and a bolt or pin disposed in the guide housing that can be displaced in the axial direction of extension of the guide housing, the bolt or pin driven by the auxiliary drive to accelerate the flowable medium in the direction of the disconnection point, wherein the flowable medium is accelerated by the auxiliary drive in the direction of the disconnection point to exert pressure on the disconnection point and wherein the flowable medium upon direct contact with the disconnection point causes the disconnection point to mechanically disconnect the first and the second connecting parts from one another.
