Description
Verfahren zur Herstellung von Elektroisolierkörpern und -überzügen Die Erfindung betrifft ein Verfahren zur Herstellung von Elektroisoliarkörpern und-ilberziigen, Bekannte Isolierstoffe auf der Grundlage von Kunstharzen haben den Nachteil, da# die bewerkstelligte Elektroisolierung gegenüber Wärmestö#en unstabil ist und das Fehlen eines faserigen Füllstoffes die mechanische Festigkeit bei astung herabsetstv Isolierstoffe auf der Grundlage von Epoxyharzkompositionen, die als 'iillstoffe Glasfasern und zwar in Mengen von bis zu 60 % enthalten, haben den Nachteil, da# der hohe Glasfasergehalt der Isolierschicht die elektrische Festigkeit herabsetzt; auch wird die Beständigkeit der Isolierschicht gegen scharfen Temperaturwechsel herabgesetzt) Die der Erfindung zugrundeliegende Aufgabe/+eines Verfahrens zur Herstellung von Elektroisolierstoffen und -überzügen, die eine hohe elektrische und mechanische Festigkeit, Geschlossenheit und Wärmeleitfähigkeit aufweisen und deren l@@eerer Au@-/+ bezweckt die Beseitigung der genannten Mängel durch Entwicklung dehnungskoeffizient im Temperaturbereich von-50 bis +150° C dem des Kupfers nahekommt. Process for the production of electrical insulating bodies and coatings The invention relates to a method for the production of electro-insulating bodies and covers, Known insulating materials based on synthetic resins have the disadvantage that # the electrical insulation that has been achieved is unstable with regard to thermal impacts, and that The lack of a fibrous filler reduces the mechanical strength when exposed to knots Insulating materials based on epoxy resin compositions, which are used as' iillstoffe Glass fibers in amounts of up to 60% have the disadvantage that # the high glass fiber content of the insulating layer reduces the electrical strength; also the resistance of the insulating layer to sharp temperature changes reduced) The object on which the invention is based / + a method for production of electrical insulation materials and coatings, which have a high electrical and mechanical Have strength, cohesion and thermal conductivity and their l @@ eerer Au @ - / + aims to eliminate the mentioned deficiencies through development expansion coefficient in the temperature range from -50 to + 150 ° C comes close to that of copper.
Gemäß der Erfindung wird die gestellte Aufgabe in der Weise gelost, daB man Gemische von 19 bis 24 % Glasfasser 33 bis 43 % Glimmerpulver und 38 bis 48 % einer Epoxrherzkomposition, die aus einer Mischung von Epozyharz mit cis-3,6-Endomethylen-1,2,3,6-tetrahydrophthalsäuretnhydrid und d Methylphenylphenylpolysiloxan im Verhältnis vom 3 bis 5 : 2,8 bis 3,2 : 0,8 bis 2, 0 besteht, nach der Verformung unter Erhitzen härtet.According to the invention, the task set is achieved in such a way that that mixtures of 19 to 24% glass fiber 33 to 43% mica powder and 38 to 48% of an epoxy heart composition consisting of a mixture of epoxy resin with cis-3,6-endomethylene-1,2,3,6-tetrahydrophthalic anhydride and d methylphenylphenylpolysiloxane in the ratio of 3 to 5: 2.8 to 3.2: 0.8 to 2.0 exists, hardens after deformation with heating.
Zweckmä#igerweise wird die Hämung der Gemische zuerst bei einer Temperatur von etwa 130° C in Laufe von etwa zwei Stunden und dann bei einer Temperatur von etwa 180° C währen etwa 20 Stunden durchgeführt.Appropriately, the mixture is first hemmed at one temperature of about 130 ° C in the course of about two hours and then at a temperature of about 180 ° C for about 20 hours.
Ein Elektromotor einer Serienelektrolokomotive mit einer Leistungsfähigkeit von 790 kW, deren Polspulen unter Anwendung eines erfindungsgemä# hergestellten Elektroisolierstoffes verfertigt sind, t an den Polspulen im Vergleich zu den bekannten Spulen eine Herabsetzung der Kupferüberhitzung von ungefahr 40 % auf, wodurch die Leistungsfähigkeit des Elektromotors derselben Abmessungen xm etwa 100 kW erhöht werden kan. n.An electric motor of a series electric locomotive with a capacity of 790 kW, the pole coils of which using a # manufactured according to the invention Elektroisolierstoffes are made, t on the pole coils compared to the known Coils reduce copper overheating of about 40 %, increasing the efficiency of the electric motor of the same dimensions xm about 100 kW can be increased.
Die herabgesetzte Kupferüberhitzung der erfindungsgemä# isolierten Spulen bleibt auch bei langerem Betrieb konstant oder wird noch weiter erniedrigt, wodurch die Lebensdauer der Elektromaschine verlangert wird.The reduced copper overheating of the insulated according to the invention Coil remains constant even with longer operation or is further reduced, whereby the service life of the electric machine is extended.
