Description

Verfahren zur Herstellung von elektrischen Preßisoliermassen mit eingebetteten 1Vletallteilen. Isoliermassen hoher Oberflächenisolation besitzen meist nicht die genügende mechanische Festigkeit. Die Festigkeit des Isoliermittels wird häufig dadurch erreicht, daß zähe, weniger hochwertige Isolierstoffe die Hauptmasse bilden und die hochisolierenden Stoffe mehr an der Oberfläche sitzen. -Wenn in derartige oder sonstige Isolierstoffe Metallteile eingebettet würden, würden die Metallteile in dem geringwertigen Isolierstoff nicht genügend fest und nicht genügend isoliert sitzen. Um dies, zu erreichen, müßten die eingebetteten Metallteile auch möglichst mit hochwertigem Isolierstoff umgeben werden.Process for the production of electrical insulation compounds with embedded 1 Metal parts. Insulating compounds with high surface insulation usually do not have the sufficient mechanical strength. The strength of the insulating agent becomes common achieved in that tough, less high-quality insulating materials form the main mass and the highly insulating materials sit more on the surface. -If in such or other insulating materials were embedded in metal parts, the metal parts would Insufficiently strong and insufficiently insulated in the inferior insulating material sit. In order to achieve this, the embedded metal parts should also, if possible be surrounded with high quality insulating material.

Nun ist bekanntlich die Bindung zwischen den eingebetteten Metallteilen und den sie umgebenden Isolierstoffen in der Regel ungenügend. Isolierstoffe und Metall besitzen bei der Verarbeitung nicht immer gleiche Temperaturen; sie dehnen sich verschieden aus, kühlen sich verschieden ab usw. Um zu erreichen, daß die Verbindung eine möglichst innige wird, verfährt man deshalb am zweckmäßigsten so, daß man die eingebetteten Metallteile während der Verarbeitung direkt oder indirekt elektrisch beheizt; direkt, indem man sie mit äußeren Stromquellen in Verbindung bringt, indirekt, indem man sie mit Hochfrequenzströmen, die durch benachbarte Spulen erregt werden , beheizt. Wenn direkt beheizt wird, so muß die Zuleitungsstrecke nach der Beheizung entfernt und .die dadurch entstehenden Hohlräume durch Isoliermasse ausgefüllt werden.Well known is the bond between the embedded metal parts and the insulating materials surrounding them are generally inadequate. Insulating materials and Metals do not always have the same temperatures during processing; stretch them cool down differently, cool down differently, etc. To achieve that connection becomes as intimate as possible, it is therefore most expedient to proceed in such a way that the embedded metal parts during processing directly or indirectly electrically heated; directly, by bringing them into contact with external sources of electricity, indirectly, by exposing them to high frequency currents that are excited by adjacent coils , heated. If heating is used directly, the feed line must be after heating removed and .the resulting cavities are filled with insulating compound.

Die elektrische Beheizung der Metallteile bringt es. mit sich, daß eine innige. Verbindung gerade an den Metallteilen stattfindet, und zwar kann die Beheizung s :o erfolgen, daß man die Erwärmung allmählich abklingen läßt und so Abkühlung der Metallteile und Isolierstoffe in übereins,timmung bringt.The electrical heating of the metal parts brings it. with that an intimate one. Connection takes place straight to the metal parts, namely the Heating s: o take place so that the heating can gradually subside, and so on Cooling down of the metal parts and insulating materials brings them into harmony.

Wird die Masse während der Erwännungsperiode noch gleichzeitig unter Druck gehalten, so muß unter allen Umständen eine innige Verbindung zwischen Metall und Isolierstoff eintreten.Will the mass still fall at the same time during the naming period Pressure maintained, an intimate bond between metal must be maintained under all circumstances and insulating material enter.

Wird dass, Verfahren angewendet, um geschichtete Isolierstoffe mit Metalleinlagen zu versehen, so ist durch Erwärmung der Metalleinlagen und Anwendung entsprechenden Druckes eine größere Dichte und infolgedessen auch höhere Dielektrizitätskonstante dies, Isoliermittels. zu erreichen. Sollen z. B. I%ondensatordurchführungen, die aus abwechselnden Schichten von Metall und Isolierstoff bestehen, nach diesem Verfahren hergestellt werden, so würde man wesentlich günstigere Anordnungen erhalten, als. wenn durch Druck allein die dazwischenliegenden Luftschichten ausgetrieben werden müßten. Ähnliches könnte man auch bei Herstellung von Kondensatoren usw. erreichen.That, method is applied to using layered insulation materials To provide metal inserts, so is by heating the metal inserts and application corresponding pressure a higher density and consequently a higher dielectric constant this, isolating agent. to reach. Should z. B. I% ondensator bushings, the consist of alternating layers of metal and insulating material, according to this process are produced, one would get much cheaper arrangements than. when pressure alone expels the layers of air in between would have to. Something similar could be achieved in the manufacture of capacitors, etc.

Sollen Isolierstücke als. Versteifung im Innern Metalleinlagen erhalten, die nach außen nicht zutage treten, so könnte man durch Aufrauhen dieser Metallteile und @entspreclzende Erwärmung erreichen, daß sich der Isolierstoff mit Vorsprüngen, Rissen, feinsten Teilchen -des Metalls eng verbindet und so, tatsächlic'h ein zusammenhängendes Gefüge gibt.Should insulating pieces be used as. Reinforcement inside received metal inserts, which do not appear to the outside, so one could get through Roughening These metal parts and @ appropriate heating achieve that the insulating material with projections, cracks, the finest particles of metal closely connected and so, actually there is a coherent structure.

Ganz besonders wichtig wird aber auch die Erwärmung bei Metallteilen, die nicht nur im Innern des Isolierstoffs, sondern auch nach außen verlaufen, weil gerade bei dieser Anardnung die Abkühlung der Metallteile eine andere ist als die des Isolierstoffs. Wird das Metall genügend lange elektrisch erwärmt und der Strom bzw. die Erwärmung allmählich verringert, so wird auch hier die Verbindung eine viel innigere sein, als wenn sich das Metall allein abkühlen kann.The heating of metal parts is also particularly important, which run not only inside the insulating material, but also outside, because especially with this arrangement, the cooling of the metal parts is different from that of the insulating material. If the metal is heated electrically for a long enough time, and so is the current or the heating gradually decreases, the connection becomes one here too be much more intimate than when the metal can cool down on its own.
