Description

Elektrisch isolierte luft- und wasserdichte sowie drucksichere Leitungsdurchführung für Pupinspulenkästen Der innere .Raum von Pupinspulenkästen besteht bekanntlich im allgemeinen aus . zwei Teilen, dem eigentlichen Spulenraum und dem. darüber befindlichen Schaltraum. Die Kabelenden werden unmittelbar in den oberen Schaltraum eingeführt, so daß die Verspleißungen der Adern mit den Spulenzuführungen in den oberen Schaltraum zu liegen kommen.Electrically insulated airtight, watertight and pressure-proof cable bushing for pupin coil boxes The inner space of pupin coil boxes is known to exist generally off. two parts, the actual coil room and the. located above Control room. The cable ends are inserted directly into the upper control room, so that the splices of the wires with the coil leads in the upper control room come to rest.

Wenn der Spulenraum nicht mit fester oder flüssiger Isoliermasse ausgegossenwerdensoll, müssen- Schalt- und Spulenraum durch eine Luft- und wasserdichte sowie drucksichere Zwischenwand voneinander getrennt werden. Diese Zwischenwand besteht im allgemeinen aus Metall. Die Leitungsdurchführungen durch diese Metallwand in dea Spulenkasten bereiten daher besondere Schwierigkeiten.If the coil space is not to be filled with solid or liquid insulating compound, Must-switch and coil room through an airtight, watertight and pressure-proof Partition wall to be separated from each other. This partition generally exists made of metal. The cable bushings through this metal wall in the coil box therefore cause particular difficulties.

Bei einer bekannten Ausführung besteht die Wandung zwischen Spulen und -Schaltraum aus einer Metällplatte, die an einigen Stellen Aussparungen aufweist, auf die besondere Isolierplatten mit eingegossenen oder eingepreßten Lötstiften als Stromeinführungen aufgelegt sind. Zur Herstellung einer luft-und wasserdichten sowie drucksicheren Stromeinführung in den Spulen'kasten sind die in Isolierstoffplatten eingegossenen oder eingepreßten Lötstifte jedoch 'wenig geeignet, da eine Lockerung der Lötstifte und auch der Isolierplatten in der Metallwand mit der Länge der Zeit umvermeidlich ist. Durch eine Lockerung der Lötstifte bleibt dann die absolute Luft- und Wasserdichtigkeit sowie Drucksicherheit der Stromdurchführungen nicht mehr aufrechterhal;en.In a known embodiment, the wall is between coils and switch room made of a metal plate, which has recesses in some places, on the special insulating plates with cast or pressed-in solder pins are placed as current inlets. To make airtight and watertight as well as pressure-proof power entry in the coil box are in insulating panels Cast in or pressed-in solder pins, however, are not very suitable because they are loosened the soldering pins and also the insulating plates in the metal wall with the length of time is inevitable. By loosening the soldering pins, the absolute air and watertightness and pressure safety of the electrical feedthroughs are no longer maintained.

Es ist bereits bekannt, metallische Leiter in Durchführungen aus anorganischen Isolierstoffen einzusetzen und mit Hilfe von Glasflüssen mit diesen zu verschmelzen. Ferner ist es auch bereits bekannt, lackisolierte cleIctrische Leiter in Bohrungen von Isolierdurchführungen aus Porzellan einzusetzen und den Zwischenraum zwischen beiden mit tiefschmelzenden Leg'erungenauszugießen. Doch kommt; die erste dieser beiden bekannten Ausführttü, gen für den Verwendungszweck gemäß der Erfindung aus Gründen der Montage; d_ezweite wegen der mangelnden Beständigkeit der Abd:ehtung nicht in Frage.It is already known to use metallic conductors in bushings made of inorganic To use insulating materials and to fuse them with the help of glass fluxes. Further it is also already known, enamel-insulated clever conductors to be used in bores of insulating bushings made of porcelain and the space in between to be poured out between the two with deep-melting layers. But come; the first these two known embodiments for the purpose according to the invention for reasons of assembly; d_second because of the lack of durability of the seal out of the question.

Gegenstand der Er Findung ist eine elektrisch isolierte, luft- und wasserdichte sowie drucksichere Leitungsdurchführung für Pupinspulenkästen, bei der gemäß der Erfindung die Leitungsdurchführungen aus keramischen Stoffen, beispielsweise aus Porzellan, mit zwei aufgebrannten Metallbelegungen versehen sind, von denen die eine mit der Metalldeckplatte des Spulenkastens und die andere mit den Leitern und/oder Spulenzuführungen verlötet sind. Verfahren zur Verschmelzung von keramischen Werkstoffen mit Metallen sind bekannt.The subject of the invention is an electrically isolated, air and watertight and pressure-proof cable bushing for pupin coil boxes, at according to the invention, the line bushings made of ceramic materials, for example made of porcelain, with two burned-on metal coverings, one of which one with the metal cover plate of the coil box and the other with the conductors and / or coil leads are soldered. Method of fusing ceramic Materials with metals are known.

Eine Durchführung ist in der Abbildung beispielsweise dargestellt. Sie besteht aus dem Zylinder r aus kerajnischem Werkstoff, welcher mit dem Metallring 4. und der Metallkappe 3 luft- und wasserdicht sowie drucksicher verschmolzen ist. Der Metallring 4 kann mit der Zuischenwand 6 des Pupinspulenkastens verlötet.werden. Der Isolator t und seine Metallkappe 3 besitzen eine durchgejicnc@e Bohrung, durch die der Spulenzulejtungsdraht a hindurchgesteckt ist. Der Spulenzuleitungsdraht 2 , muß dann mit der 'TetAlkappe 3 verlötet werden, so daß der unter-_h-lb der Metallplatte 6 be_indl:che Spulenaum durch das Lot 7 gle:chz°itig Luft- und was:;erd:cht sowie drucksicher abgeschlossen wird.One implementation is shown in the illustration, for example. It consists of the cylinder r made of Kerajnischem material, which with the metal ring 4. and the metal cap 3 is fused airtight, watertight and pressure-proof. The metal ring 4 can be soldered to the additional wall 6 of the pupin coil box. The insulator t and its metal cap 3 have a durchgejicnc @ e hole which the coil supply wire a is pushed through. The coil lead wire 2, must then be soldered to the 'TetAlkappe 3, so that the under-_h-lb of the metal plate 6 be_indl: che coil space through the perpendicular 7 same: chz ° itig air and what:; earth: cht as well is closed in a pressure-proof manner.

Der besondere Vorteil dieser Stromdurchführungen besteht darin, daß keine Lötstifte mehr verwendet zu werden brauchen, deren luft- und wasserdichte sowie drucksichere Isolierung gegenüber der Metallwand stets besondere Schwierigkeiten bereitete. Die Anwendung des keramischen Isolators verbürgt neben einer luft- und wasserdichten sowie drucksicheren vor allem auch eine mechanisch feste Stromdurchführung.The particular advantage of these current feedthroughs is that no more solder pins need to be used, their airtight and watertight as well as pressure-proof insulation against the metal wall always special difficulties prepared. The use of the ceramic insulator guarantees air and watertight and pressure-proof, and above all a mechanically solid electrical feedthrough.
