The device for electric potential separation, the mannered null toroidal core in order to produce the toroidal core choke and the toroidal

摘要

The present invention relates to a device for potential separation suitable for assembly into the core hole of the toroidal core (44). In accordance with the present invention, the central portion having an axial torsion (1), extending outwardly, is provided a deformable web and (21, 22, 23) about an axis twisting in the torsional direction, the web the end on the side opposite to (1) a central portion (21, 22, 23) is an insulating region that is thicker than the radially extending, preferably, the web (21, 22, 23), respectively I have a (31, 32, 33).
