Detachable connecting arrangement, has recess whose inner diameter is large such that electrical partition between coil and casing is provided in radial direction through annular space between inner diameter and outer diameter of coil

摘要

The arrangement has two coaxially arranged pipe sections (1, 2) separated from each other by an insulator (3), where each section has a rotating coil (4, 5). An annular space (7) or insulator body (8) is electrically insulated in radial direction. An inner contour of a casing (6) has a recess at an axial distance to a deforming region of wedge-shaped elements (12). An inner diameter of the recess is large such that an electrical partition between the coil and the casing is provided in radial direction through the annular space between the inner diameter and an outer diameter of the coil.
