Abstract:
1. A plug-in high-voltage bushing for connecting an external electrical conductor to a metal-encapsulated component, which is filled with a liquid or gaseous insulating agent, of a high-voltage installation, the bushing comprising: an electrical conductor that is routed along an axis and has a plug contact and a connection for the external conductor; an insulator that is attached to the electrical conductor; a mounting flange that is attached to the insulator; a shield that is cast onto an outer surface of the insulator and that extends in an axial direction from the mounting flange to the connection for the external electrical conductor; and a device that surrounds the electrical conductor and controls an electrical field which acts when high voltage is applied, wherein the insulator has a tapering section that dielectrically strengthens a joint after insertion of the bushing into a plug part that closes a component of the high-voltage installation forming a seal for the insulating agent; wherein the joint is arranged between an insulating sleeve of the plug part and the tapering section of the insulator, wherein the field control device is in the form of a capacitor winding, and the capacitor winding has capacitor plates which are electrically isolated from one another, are kept at a distance from one another in a radial direction by insulating film, and are integrated in the insulator by embedding the capacitor winding in a cured polymer compound; wherein the capacitor plates are passed through the mounting flange into the tapering section of the insulator, and wherein a surface, which bounds the joint, of the insulator includes an elastically deformable insulation which is held on the capacitor winding.
