Description

Drosselspule für Hochspannungen mit Verspannungsbolzen aus Isoliermaterial und mehreren in axialer Richtung aneinande;gereihten Scheibenspulengruppen Es sind Drosselspulen für hohe Spannungen vorgeschlagen worden, die aus mehreren hintereinandergeschalteten Scheibenspulen bestehen, die durch isolierende Zwischenstücke voneinander getrennt und durch Verspannbolzen zusammengehalten sind. Um bei derartigen Spulen eine möglichst gleichmäßige Feldverteilung zu erreichen, wie dies zur Bewältigung von Höchstspannungen notwendig ist, ist weiter vorgeschlagen worden, als Verspannbolzen für die Drosselspulen auf Zug beanspruchte Isolatoren zu verwenden. Bei Anordnungen für sehr hohe Spannungen werden aber einerseits sehr große Abstände iwischen den einzelnen Scheibenspulen sowie andererseits auch eine sehr große Zahl von Scheibenspulen erforderlich, so daß Isolatorbolzen, etwa aus Porzellan, Steatit u. dgl., in einer der axialen Länge der Spulenanordnung entsprechenden Länge nicht mehr in der erforderlichen Materialbeschaffenheit und Zuverlässigkeit hergestellt werden können, wenigstens zu wirtschaftlichen Bedingungen. Nach der vorliegenden Erfindung werden daher derartige Drosselspulen in in axialer Richtung aneinandergereihte Scheibenspulengruppen unterteilt, die voneinander durch Zwischenstücke größerer axialer Ausdehnung getrennt sind und durch mehrere Bolzen etwa von der Länge der Einzelgruppen verspannt werden, die miteinander am besten gelenkig verbunden werden. In vielen Fällen wird es, um die Bolzen bei Aufrechterhaltung der erforderlichen Zugfestigkeit miteinander verbinden zu können, notwendig sein, Metall zu verwenden, etwa indem die Verspannbolzen an den Enden mit metallenen Kappen versehen werden, in welchen kurze, metallene Bolzen kugelgelenkartig gelagert sind, die den Zug von einem Bolzen auf den anderen übertragen.Choke coil for high voltages with bracing bolts made of insulating material and several disc coil groups lined up in the axial direction are Choke coils for high voltages have been proposed, consisting of several series-connected Disc coils exist, which are separated from one another by insulating spacers and are held together by bracing bolts. In order to achieve a possible with such coils to achieve uniform field distribution, such as this to cope with maximum voltages is necessary, has also been proposed as a bracing bolt for the choke coils to use insulators subject to tensile stress. For arrangements for very high voltages but on the one hand there are very large distances between the individual disc coils and on the other hand a very large number of disc coils are required, see above that insulator bolts, for example made of porcelain, steatite and the like, in one of the axial length the length corresponding to the coil arrangement is no longer in the required material properties and reliability can be established, at least on economic terms. According to the present invention, therefore, such choke coils in axial Direction of lined up disc coil groups divided by one another Intermediate pieces of larger axial extent are separated and by several bolts about the length of the individual groups that work best with each other be articulated. In many cases it will be to keep the bolts in place to be able to combine the required tensile strength with each other, Use metal, for example by attaching the bracing bolts to the ends with metal caps be provided, in which short, metal bolts are mounted like a ball joint, which transmit the pull from one bolt to the other.

Um hierbei die für Höchstspannungen erforderliche Homogenität des Feldes aufrechtzuerhalten, werden diese Metallteile zweckmäßig hinreichend weit von den nächst benach-. barten Windungslagen abstehend angeordnet. Hierzu werden zwischen den äußersten Scheibenspulen je zweier aneinandergereihter Spulengruppen Distanzstücke von entsprechend großer axialer Ausdehnung gelegt.In order to achieve the homogeneity of the To maintain the field, these metal parts are expediently sufficiently wide from the next neighboring. barten winding layers arranged protruding. To do this will be between the outermost disc coils there are two coil groups in a row Placed spacers of a correspondingly large axial extent.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Die Drosselspule besteht hierbei aus einer Reihe von spiralförmig gewickelten Scheibenspulen i, die durch Zwischenstücke 2 aus Isoliermaterial, etwa Steatit, voneinander getrennt sind. Das mittelste Zwischenstück 3, das die Drosselspule gewissermaßen in zwei Spulengruppen zerlegt, besitzt hierbei eine erheblich größere axiale Ausdehnung. Die Spule ist durch auf Zug beanspruchte Isolierbolzen 6 verspannt, die an ihrem Ende mit metallenen Kappen 7 versehen sind, in denen Gelenkbolzen 9 kugelgelenkartig gelagert sind. An den äußeren Enden sind die Bolzen 9 durch metallene Druckplatten q. geführt und durch Muttern i i verschraubt. An den inneren Enden, an denen zwei Bolzen aneinanderstoßen, stellen die metallenen Bolzen 9 die mechanische Verbindung der Bolzen 6 dar. Um mit einer möglichst geringen Zahl von Bolzen auszukommen, sind die Bolzen in der erforderlichen Anzahl gleichmäßig auf den Umfang der Drosselspule verteilt und durch eine in der Mitte der radialen Breite der einzelnen Scheibenspulen angeordnete Aussparung geführt. Auf diese Weise wird auch der Druck der Bolzen annähernd gleichmäßig auf die gesamten Windungen der einzelnen Scheibenspulen verteilt. Da die Scheibenspulengruppen in der Mitte durch die isolierenden Zwischenstücke 3 hinreichend weit auseinandergehalten sind, ergibt sich zwischen den Windungen dieser Spulengruppen und den metallenen Teilen 9, durch die die Bolzen miteinander verbunden sind, ein sehr großer Abstand. Demzufolge werden diese Metallteile, die ja gewissermaßen den Mittelbelag eines durch die hintereinandergeschalteten Bolzen gebildeten Kondensators darstellen und als solcher gegen die beiden äußeren Beläge, d. h. die Druckplatten, gleich große Potentialunterschiede aufweisen, also einen Spannungswert annehmen, der etwa in der Mitte zwischen den Potentialen der Eingangs- und der Ausgangswindung der Drosselspule liegt. - Aus diesem Grunde besteht zwischen den Metallteilen 9 und den benachbarten Windungen der Scheibenspulengruppen, die, als in der Mitte der Spulenanordnungen liegend, gleichfalls annähernd die halbe Betriebsspannung führen, kein wesentlicher Potentialunterschied, der bei dem großen Abstand zwischen den Metallteilen und den Windungen auf die gleichmäßige Feldverteilung in der ganzen Spule ohne störenden Einfluß ist.The choke coil here consists of a series of spirals wound disc coils i, which by spacers 2 made of insulating material, for example Steatite, are separated from each other. The middle intermediate piece 3, which is the choke coil as it were in two Disassembled coil groups, here has a considerably larger axial expansion. The coil is made up of isolating bolts that are subjected to tensile stress 6 braced, which are provided at their end with metal caps 7 in which hinge pins 9 are mounted like a ball joint. At the outer ends, the bolts 9 are made of metal Printing plates q. guided and screwed through nuts i i. At the inner ends at which two bolts meet, the metal bolts 9 represent the mechanical ones Connection of the bolts 6 represents. In order to get by with the smallest possible number of bolts, the required number of bolts are evenly spaced around the circumference of the choke coil distributed and by one in the middle of the radial width of each disk coil arranged recess out. In this way the pressure of the bolts is also approximate evenly distributed over the entire turns of the individual disc coils. There the disc coil groups in the middle through the insulating spacers 3 sufficiently are kept far apart, results between the turns of these coil groups and the metal parts 9 by which the bolts are connected to each other very large distance. As a result, these metal parts are, so to speak, the Middle layer of a capacitor formed by the bolts connected in series represent and as such against the two outer coverings, d. H. the printing plates, have equally large potential differences, i.e. assume a voltage value, which is roughly in the middle between the potentials of the input and output winding the choke coil is located. - For this reason there is 9 between the metal parts and the adjacent turns of the disc coil groups, which, as in the middle of the coil arrangements, also approximately half the operating voltage lead, there is no significant potential difference due to the large distance between the metal parts and the windings on the uniform field distribution throughout Coil is without disturbing influence.

Die Anwendung des Erfindungsgedankens ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. Insbesondere können die Spannbolzen aus einer beliebigen, größeren oder kleineren Zahl von Teilen zusammengesetzt sein, wie sich das nach den Bedürfnissen des jeweilig vorliegenden Falles ergibt. Auch können die Bolzen in zwei konzentrischen Ringen außer- und innerhalb des Scheibenspulenringes angeordnet werden, bei großer radialer Breite der Spule auch mit in der Mitte der Spulen angeordneten Bolzen kombiniert.The application of the inventive concept is not to that shown Embodiment limited. In particular, the clamping bolts can be made from any larger or smaller number of parts to be composed, as that according to the needs of the case at hand. Also can the bolts arranged in two concentric rings outside and inside the disc coil ring are arranged with a large radial width of the coil also in the center of the coils Bolts combined.
