摘要： A winding machine for electrical coils to be wound into layers has a device (2) which supplies a material (14) to the coil to be wound in order to separate adjacent layers of the coil from one another. The device (2) has a device (18) for producing a predetermined breaking point in the material (14), and a measuring unit (20). The measuring unit (20) determines when the device for producing a predetermined breaking point is to be activated in order to produce a predetermined breaking point in the material (14). The device also has a guide device (26) which fixes the material (14) on the coil to be wound in the vicinity of the predetermined breaking point at a predetermined time, in order to sever the material at the predetermined breaking point. The winding machine therefore anticipates when a layer change is required, in order to then produce a predetermined breaking point in the material at a distance from the coil. The predetermined breaking point is pulled through as far as the coil, and this enables the material to be guided in a controlled and reliable manner. The material is torn off at the predetermined breaking point only after the material is secured on the coil.

摘要： A method is described for winding a coil for a transformer, with the coil winding being introduced into a cylindrical, tubular insulating body. In order to shorten the coil length and to reduce the amount of insulating material, as well as to reduce the core weight, the individual winding wire layers are wound radially one on top of the other at the points at which the winding wire layers are connected to one another, so that the respective adjacent turn ends each lie on one radial plane. This is achieved by providing end wall sections which are used to guide and maintain the shape of the insulating windings or layers.

摘要： The invention relates to a method of impregnating components with momomer-free non radically polymerizing impregnating agents, which are liquid at room temperature or can be liquefied through heating and hardened by the combined use of heat and high-energy radiation. The components are impregnated at ambient temperature or in a heated state or are heated during impregnation before being treated with high energy radiation simultaneously with or after thermal hardening.

摘要： A method of manufacturing transformer windings embedded in casting resin is disclosed which utilizes an integrated winding mandrel for producing a non-standard oval shaped epoxy encapsulated low voltage coil for dry type distribution transformers. The method includes a process of winding a low voltage coil of alternate layers of copper conductor (24) and insulating tape (26), over a disposable mold formed by wrapping steel sheet material over inner mold support plates (14), the formed mold acting as both a winding mandrel and as an inner mold (20) for epoxy encapsulation. Both the inner and outer molds are made of low cost sheet metal utilizing a 'wrap and band' process. The complete winding and molding processes can all be conducted utilizing a conventional square mandrel shaft (12) on a standard coil winding machine (10).

摘要： Die Erfindung betrifft ein induktives Bauteil in Form eines Transformators oder einer Drossel, insbesondere aber einen Mittelfrequenz-Transformator, mit mindestens einer Wicklung, wobei zwischen einzelnen Lagen der Wicklung und/oder einer weiteren Wicklung eine oder mehrere Wärmebrücken-Zwischenisolationen angeordnet sind, wobei die Wärmebrücken-Zwischenisolationen flexible Isolierfolien umfassen, in die wärmeleitende Füllstoffe eingearbeitet sind, und gegenüber bisher üblichen Zwischen-, Windungs- oder Erdisolationen, z. B.: Glimmer, Polyester, Polyamide, unterschiedliche Isolierpapiere, Pressspan, Mischisolationen, auch verschiedene Harze, Guss- und Spritzgusstechniken, eine deutlich höhere Wärmeleitfähigkeit aufweisen. Die Wicklung kann hermetisch in einem Spulenumguß eingebettet sein und einen Kern aufweisen, der in einer entsprechenden Spulendurchdringung im Spulenumguß gehalten wird. Die Wärmebrücken-Isolation können auch als keramische Kacheln oder starre Überlappungselemente ausgeführt sein und optional mit Zusatzkühlern und Heatpipes ausgestattet sein, zwecks besserem Wärmeaustrag aus den Wicklungen bzw. Wärmeübertrag von Wicklungen und Kernen in andere Räume.
