Description
Papier für elektrotechnische Zwecke, insbesondere für Kondensatoren Für bestimmte Anwendungsgebiete «-erden Kondensatoren benötigt, die nur an niedrigen Betriebsspannungen liegen, dabei aber relativ große Kapazität auf kleinem Raum besitzen sollen. Zur gleichzeitigen Erfüllung dieser Bedingungen hat man bereits einlagige Papierwickelkondensatoren hergestellt oder zum Imprägnieren Dielektriken mit hoher Dielektrizitätskonstante verwendet. Auch hat man daran gedacht, in das Imprägniermittel bzw. auf die Belege fein pulverisierte Stoffe hoher Dielektrizitä tskonstante zti bringen. Das letztere Verfahren hat insbesondere den Nachteil. claß das unbedingt notwendige Abstands material die Wirksamkeit der Maßnahmen stark beeinträchtigt.Paper for electrotechnical purposes, in particular for capacitors For certain areas of application, capacitors are required that are only at low Operating voltages lie, but have a relatively large capacity in a small space should. To meet these conditions at the same time, you already have single-ply Paper wound capacitors are made or for impregnating dielectrics with high Dielectric constant used. It has also been thought of in the impregnation agent or finely powdered materials with a high dielectric constant zti bring. The latter method has the particular disadvantage. absolutely must necessary spacing material greatly affects the effectiveness of the measures.
Es ist weiterhin bekanntgeworden, z. B. Titandioxyd als Imprägniermittel zu verwenden, d. h. das Titandioxyd wird mit Wachs oder Harz vermengt und das Papier mit diesem Gemisch imprägniert. Wenn auch hierbei das Titandioxyd feinste Korngröße aufweist, so läßt sich doch keine wesentliche Verbesserung des Kondensators erzielen, da das Titandioxyd nicht genügend in die Poren des Kondensatorpapiers eindringt.It has also become known, e.g. B. Titanium dioxide as an impregnating agent to use, d. H. the titanium dioxide is mixed with wax or resin and the paper impregnated with this mixture. Even if the titanium dioxide is the finest grain size no significant improvement in the capacitor can be achieved, because the titanium dioxide does not penetrate sufficiently into the pores of the capacitor paper.
Bisher wurden für elektrotechnischeZwecke grundsätzlich nur Papiere verwendet, die nicht beschwert waren. Die für andere, nicht elektrotechnischeZwecke verwendetenPapiere wurden teilweise beschwert. und zwar mit Aluminiumoxyd, Kaolin. Gips, Schwerspat, Magiiesiumsulfat usw.. wobei der Anteil des Beschwerungsmittels sehr verschieden war und sich mehr nach äußeren Eigenschaften richtete.So far, only papers have been used for electrotechnical purposes used that were not complained. For other, non-electrotechnical purposes papers used were partially weighted down. namely with aluminum oxide, kaolin. Gypsum, barite, magnesium sulfate, etc .. where the proportion of the weighting agent was very different and was more based on external properties.
Erfindungsgemäß wird für elektrotechnische Zwecke. insbesondere zur Herstellung von Kondensatoren, die zur Erzielung einer hohen Kapazität aus einer einzigen. gegebenenfalls mit Imprägniermitteln hoher Dielektrizitätskonstante (größer als 5) behandelten Papierlage aufgebaut sind, ein Papier verwendet, das durch eine ausschließlich mechanische Behandlung, wie Einwalzen, also ohne Zuhilfenahme von Imprägniermitteln oder von Bindemitteln, mit festen Stoffen hoher Dielektrizitätskonstante (größer als 2o) beschwert ist.According to the invention for electrotechnical purposes. especially for Manufacture of capacitors to achieve high capacitance from a single. if necessary with impregnating agents with a high dielectric constant (larger are constructed as 5) treated paper layer, a paper is used, which is through a exclusively mechanical treatment, such as rolling in, i.e. without the aid of Impregnating agents or binding agents with solid materials with a high dielectric constant (greater than 2o) is weighted.
Der Anteil der Beschwet'ungsmittel, auf das Papiergewicht bezogen. soll mindestens io°/o betragen. Als besonders wirksam hat es sich hierbei herausgestellt, Beschwerungsmittel extrem hoher Dielektrizitätskonstante zu verwenden. wie Bleisulfat. Bleikarbonat, Titandioxyd usw., also Stoffe, bei denen die Dielektrizitätskonstante größer als 2o ist.The proportion of complaints, based on the weight of the paper. should be at least 10%. It has proven to be particularly effective here Use extremely high dielectric constant weighting agents. like lead sulfate. Lead carbonate, titanium dioxide, etc., i.e. substances with which the dielectric constant is greater than 2o.
