Abstract:
1. A current transformer, comprising a current transformer casing and at least one current transformer core that is arranged on a core carrier tube and serves for measuring a current flowing through a conductor, wherein the core carrier tube contains a fill opening for slipping the current transformer core on the core carrier tube, and wherein the core carrier tube is configured to be connected to a switchgear housing by means of installation flanges wherein a) the fill opening is provided with a mounting contour that serves for absorbing axial forces and the outside diameter of which is smaller than an outside diameter of an installation flange for the core carrier tube, wherein b) a mounting means that serves for the installation of the core carrier tube in the region of the fill opening is configured to be mounted on the mounting contour and wherein the mounting contour contains a projection that projects radially outward on the fill opening, wherein said projection engages with a groove on the mounting means and transmits axial tensile forces acting upon the mounting means to the core carrier tube.
