    摘要: Mold-free resin-insulated coil windings are obtained by applying continuous fibers embedded in a quasi-solid-state epoxy-resin matrix, e.g. in the form of a tape, to the coil windings. The tape is locally heated up to the melting point of its polymer matrix, and is subsequently pressed against the winding body. The heated and fused resin of the tape, which is pressed onto the coil, flows under pressure into the voids and gaps between the coil windings and fills them up, thereby hermetically insulating the coil windings. After leaving the heating and pressing apparatus the fused epoxy resin becomes solid again. The resulting curing process is thus considerably simplified and shortened, compared to the state of the art.

    摘要: A high-voltage bushing has a conductor and a core surrounding the conductor, wherein the core comprises a sheet-like spacer, which spacer is impregnated with an electrically insulating matrix material. The spacer is wound in spiral form around an axis, the axis being defined through the shape of the conductor. Thus, a multitude of neighbouring layers is formed. The core further comprises equalization elements in appropriate radial distances to the axis. The equalization elements comprise electrically conductive layers, which layers have openings, through which openings the matrix material can penetrate, and in that the equalization elements are applied to the core separately from the spacer. The electrically conductive layers can be net-shaped, grid-shaped, meshed or perforated. The openings are fillable with the matrix material, e.g., a particle-filled resin can be used.

    摘要: An exemplary plug-in high-voltage bushing connects an electrical conductor to a metal-encapsulated component, which is filled with insulating agent, of a high-voltage installation. The bushing is rotationally symmetrical with respect to an axis and has a centrally routed electrical conductor, a field control device and an insulator surrounds the electrical conductor. The bushing also includes a tapering section that dielectrically strengthens a joint after insertion of the bushing into a plug part, which forms a seal for the insulating agent. The joint is arranged between an insulating sleeve of the plug part and the tapering section of the insulator. The bushing has capacitor plates, which are electrically isolated from one another by an insulating film, are integrated into the insulator, and pass through the mounting flange into the tapering section of the insulator.
