Description
Hochstromdrosselspule für Gleichstromanlagen Die Erfindung bezieht sich auf eine Hochstromdrosselspule für Gleichstromanlagen mit durch Isolierzwischenlagen voneinander getrennten Windungen eines hochkant gewickelten Leiters, der Bohrungen zur Aufnahme von durchgehenden Spannbolzen besitzt.High current choke coil for direct current systems The invention relates on a high-current choke coil for direct current systems with through insulating interlayers separate turns of an edgewise wound conductor, the holes for holding through clamping bolts.
Bei Spulen der vorgenannten Art wurden bisher die Windungen durch Bügel zusammengehalten. Dies ist jedoch eine recht unstabile Befestigung, da sich bereits nach kurzer Zeit eine Verschiebung der Leiter gegenüber dem Isolationsmaterial einstellt. Eine starre Spulenform ist demnach nicht gewährleistet. Es sind zwar auch schon Zugbolzen aus Isoliermaterial zur Befestigung vorgeschlagen worden, doch können hiermit keine beträchtlichen Kräfte aufgenommen werden. Der erforderliche, verhältnismäßig große Bolzendurchmesser schwächt den Leiterquerschnitt beträchtlich. Schließlich weisen alle bekannten Anordnungen den Nachteil auf, daß die Leiterabmessungen der Drossel nicht unter dem Gesichtspunkt einer möglichen Dämpfung des Kurzschlußstromes gewählt wurden.In the case of coils of the aforementioned type, the windings have hitherto been through Hangers held together. However, this is a rather unstable attachment because Already after a short time a shift of the conductor in relation to the insulation material adjusts. A rigid coil shape is therefore not guaranteed. It is true Draw bolts made of insulating material have also been proposed for fastening, but no considerable forces can be absorbed with this. The required relatively large stud diameter weakens the conductor cross-section considerably. Finally, all known arrangements have the disadvantage that the conductor dimensions the choke not from the point of view of possible damping of the short-circuit current were chosen.
Die beschriebenen Mängel lassen sich vermeiden, wenn erfindungsgemäß die Leiterwindungen, deren Leiterbreite ein Fünftel bis ein Zwanzigstel des Spuleninnendurchmessers beträgt, durch mit Isolierhülsen versehene metallische Spannbolzen, insbesondere Stahlbolzen, zusammengepreßt werden.The deficiencies described can be avoided if according to the invention the conductor turns, the conductor width of which is one fifth to one twentieth of the inside diameter of the coil is, by provided with insulating sleeves metallic clamping bolts, in particular Steel bolts, to be pressed together.
Der Vorteil des Erfindungsgegenstandes ist darin zu sehen, daß infolge der hohen mechanischen Festigkeit der Spulen die erheblichen Kurzschlußkräfte beherrscht werden können, welche in Gleichstromanlagen auftreten, und ferner die gewählten Leiterabmessungen bei raschen Stromänderungen eine wesentliche Vergrößerung des Gleichstromwiderstandes bedingen, so daß eine wirksame Dämpfung des Kurzschlußstromes erfolgt. Die hohen Beanspruchungen von Drosselspulen in Gleichstromanlagen rühren einerseits von den mitunter hohen Kurzschlußströmen und andrerseits von den dauernd pulsierenden magnetischen Kräften der Oberwellen her. Für die Herstellung einer Spule mit einem Innendurchmesser von 1 m kann beispielsweise Flachrnaterial von 10 cm Breite, also einem Zehntel des Innendurchmessers und 10 bis 20 mm Dicke verwendet werden.The advantage of the subject matter of the invention is that as a result the high mechanical strength of the coils controls the considerable short-circuit forces which occur in direct current systems, and also the selected ones Conductor dimensions with rapid current changes a significant increase in the Condition DC resistance, so that an effective damping of the short-circuit current he follows. The high stresses on choke coils in direct current systems stir on the one hand from the sometimes high short-circuit currents and on the other hand from the permanent pulsating magnetic forces of the harmonics. For making a Coil with an inner diameter of 1 m can, for example, be made of flat material from 10 cm wide, i.e. one tenth of the inner diameter and 10 to 20 mm thick will.
Es empfiehlt sich, die Leiterwindungen der erfindungsgemäßen Hochstromdrosselspule aus Aluminium oder einer Aluminiumlegierung herzustellen. Ferner ist es gemäß weiteren Merkmalen der Erfindung zweckmäßig, die Leiterbohrungen jeweils in der Mitte vorzusehen. Es können dann Spannbolzen aus gewöhnlichem Stahl Verwendung finden, da in der Leitermitte die Feldstärke im Vergleich zum Hauptfeld sehr gering ist.It is recommended that the conductor turns of the high-current choke coil according to the invention made of aluminum or an aluminum alloy. Furthermore, it is according to others Features of the invention expedient to provide the conductor bores in the middle. Clamping bolts made of ordinary steel can then be used because they are in the middle of the conductor the field strength is very low compared to the main field.
In der Zeichnung ist als Ausführungsbeispiel des Erfindungsgegenstandes ein Teil einer Hochstromdrosselspule vereinfacht dargestellt, und zwar in Fig. 1 in Ansicht und in Fig. 2 im Längsschnitt.In the drawing is an exemplary embodiment of the subject matter of the invention a part of a high-current choke coil is shown in simplified form, specifically in FIG. 1 in view and in Fig. 2 in longitudinal section.
Mit 1 ist ein die Spule bildender, hochkant gewikkelter flacher Aluminiumleiter bezeichnet, der an seinen beiden Enden 2,- 3 mit den nicht gezeigten Anschlüssen verbunden ist. Der Leiter 1 weist gleichmäßig am Umfang der Spule verteilte und in der Mitte des Leiters 1 angeordnete Bohrungen 4 auf, durch die mit einer Isolierhülse 5 versehene Spannbolzen 6 hindurchgehen. Die einzelnen Windungen des Leiters 1 sind voneinander durch Isolierringe 7 getrennt und mittels Isolierscheiben 8, Preßtellern 9, Druckfedern 10, Druckscheiben 11 und Muttern 12 zusammengepreßt.With 1 is an edgewise wound flat aluminum conductor forming the coil denotes, which at its two ends 2, - 3 with the connections, not shown connected is. The conductor 1 has evenly distributed around the circumference of the coil and in the middle of the conductor 1 arranged holes 4 through which with an insulating sleeve 5 provided clamping bolts 6 go through. The individual turns of the conductor 1 are separated from each other by insulating rings 7 and by means of insulating washers 8, press plates 9, compression springs 10, pressure washers 11 and nuts 12 pressed together.
