Claims (11)

  1. Verfahren zur Herstellung einer Spannungsspule eines Hochspannungsinstrumententransformators und Vorrichtung zur Herstellung der Isolierung einer Spannungsspule, wobei das Isolationsmaterial aus Blättern von Wicklungspapier mit längs geschnittenen Bändern besteht, die als erstes zur Isolation der einzelnen Lagen der Wicklung der Spannungsspule dienen und so eine Zwischenisolierung der Spule bilden, und dann dazu dienen, die Spule sowie die Verbindungsstelle zwischen Spule und Durchführung des Hochspannungsinstrumententransformators zu isolieren, dadurch gekennzeichnet, dass eine obere Abschirmung (17), die mit einem leitenden Stab (18) der Durchführung verbunden ist, auf den isolierten Wicklungen der Spannungsspule (10) angeordnet ist und anschließend die Spule und die Stelle der Verbindung der Spannungsspule (10) und der Durchführung mit Bändern von Wicklungspapier (16) in senkrechter Position der Spule (10) durch Wicklungen abwechselnd von der Ober- und Unterseite der Spulenfläche festgebunden ist.
  2. Ein Verfahren gemäß Anspruch 1, dadurch gekennzeichnet, dass die Dicke der Schichten der Isolation (13) der Spannungsspule (10) mit zunehmendem Abstand von der Achse der Spule abnimmt.
  3. Ein Verfahren gemäß Anspruch 1 oder 2, dadurch gekennzeichnet, dass nach der Fertigstellung des Prozesses, die Spannungsspule (10) mit der oberen Abschirmung (17) zusammenzubinden, auf die Außenfläche der Hauptisolierung des Instrumententransformators (21) der zusammengebundenen Spannungsspule (10) eine Wicklungsschicht aus halbleitendem Papier, die eine äußere Abschirmung der Spannungsspule bildet, angebracht wird.
  4. Ein Verfahren gemäß Anspruch 3, dadurch gekennzeichnet, dass, nach der Anbringung der äußeren Abschirmung auf der Hauptisolation des Instrumententransformators (21) der zusammengebundenen Spule (10), die äußere Abschirmung mit Kupferband umwickelt wird.
  5. Ein Verfahren gemäß Anspruch 1, dadurch gekennzeichnet, dass der leitende Stab (18) mit der Isolierung (19) eine vertikale Position während der Zusammenbindung der Umwicklung der Spannungsspule (10) einnimmt.
  6. Ein Verfahren gemäß Anspruch 1, dadurch gekennzeichnet, dass das Zusammenbinden der Spule (10) und der Abschirmung (17) und die Verbindung der Spannungsspule (10) mit dem isolierten leitenden Stab (18) mit Hilfe einer Schwerkraft-Wickeleinrichtung erfolgt.
  7. Vorrichtung zur Herstellung der Hauptisolierung der Spannungsspule eines Hochspannungsinstrumententransformators gemäß Verfahren nach Anspruch 1, wobei das Isolationsmaterial aus Blättern von Wicklungspapier mit längs geschnittenen Bändern besteht, die als erstes zur Isolation der einzelnen Lagen der Wicklung der Spannungsspule dienen und so eine Zwischenisolierung der Spule bilden, und dann dazu dienen, die Spule sowie die Verbindungsstelle zwischen Spule und Durchführung des Hochspannungsinstrumententransformators zu isolieren, die eine Traverse sowie Mittel zur Fixierung der Position auf der Traverse der Spannungsspule zusammen mit einer oberen Abschirmung (17) enthält, wobei die Traverse (6) an einem Rahmen (1) befestigt ist, der mit einem drehbaren Körper (2) verbunden ist, der in vertikaler Richtung beweglich auf einem Sockel angeschlossen ist.
  8. Eine Vorrichtung gemäß Anspruch 7, dadurch gekennzeichnet, dass sie einen Blockierungsmechanismus (5) enthält, um die Traverse (6) mit dem Rahmen (1) in horizontaler oder vertikaler Position zu blockieren, indem die Traverse (6) und der Rahmen (1) um einen Winkel von 90° gedreht werden.
  9. Eine Vorrichtung gemäß Anspruch 7, dadurch gekennzeichnet, dass Distanzscheiben (8) und Presshülsen (7) an den Enden der Traverse (6) angeordnet sind.
  10. Eine Vorrichtung gemäß Anspruch 7 - 9, dadurch gekennzeichnet, dass eine Halterung (9) mit einem Klemmring, an dem Körper (2) befestigt ist, um die Durchführung des Transformators in vertikaler Position zu halten.
  11. Eine Vorrichtung gemäß Anspruch 7 - 10, dadurch gekennzeichnet, dass sie eine Schraubenmutter (4) enthält, um die Höhe der Position des Rahmens (1) zu regulieren.
