PROCEDE D'OBTENTION D HUILES ISOLANTES DE VISCOSITE VARIEE POUR
CABLES.
Dans la fabrication de câbles à hautes et basses tensions, il est connu d'utiliser des huiles isolantes pour l'imprégnation de lisolement sé- ché en papiero Pour des câbles de masses ou des câbles de pression,, on a be- soin d'huiles isolantes visqueuses et pour des câbles a l'huile d'huiles iso- lantes fluides.
On impose aux propriétés électriques de ces huiles Isolantes, telles que le facteur de perte diélectrique la conductibilité,,, la résistance aux décharges 'électriques, etc., des exigences déterminéesqui dépendent du genre de câble et des sollicitations auxquelles est soumis le diélectrique du câble terminé.Lors des examens de réception du câble fini., on attache une im- portance particulière par exemple à de faibles valeurs du facteur de perte de l'isolement huile-papier du câbleo Les spécifications du Verband Deutscher Elektrotechniker (Association des Ingénieurs Electriciens allemands) (VDE), ainsi que les spécifications d'autres pays;
) par exemple en Hollande, en Suisse, en Grande-Bretagne, etc. donnent-des valeurs minima précises devant être ob- - servées dans tous les cas.
Quand on utilise les huiles de câbles isolantes usuelles disponi- bles,sur le marché provenant d'huiles de base naturelles auxquelles on ajou- te des résines, on ne peut que difficilement maintenir les valeurs minima men- tionnées du facteur de perte, surtout dans le cas des spécifications valables à 1-'étranger.
L'invention a pour but de mettre au point des huiles isolantes pour câbles qui possèdent des propriétés électriques notablement meilleures que jusqu'à présenta spécialement en ce qui concerne le facteur de perte dié- lectrique
Suivant l'idée de l'invention on utilise comme produit de départ tel que connu en sois des huiles de base naturelles;
on peut également utili-
<Desc/Clms Page number 2>
ser de la même manière des huiles de- base synthétiques-
Conformément à l'invention on purifie tout d'abord ces huiles de base naturelles et/ou synthétiques par des agents d'adsorption,\1 et on dissout ensuite dans les huiles de base,, éventuellement en ajoutant des agents solubilisants, des résidus de distillation d'huiles minérales'du bien des produits résineux naturels ou respectivement synthétiques, puri- fiés par distillation ou respectivement par des agents d'adsorption. De même,\1 il est également possible de mélanger les huiles de base avec les produits résineux et de purifier ensuite ce mélange par des agents d'adsorp- tion.
Les produits finals sont des huiles isolantes de câbles de grande va- leur, ayant en particulier des propriétés électriques qu'on n'a pas encore pu obtenir jusqu9à présent.
On peut utiliser comme agents d'adsorption des terres de blan- chiment, des gels de silice des oxydes d'aluminium, dont la teneur en eau ne peut dépasser une valeur maximum., et on peut incorporer comme rési- nes naturellespar exemple de la colophane, et comme résines artificielles, par exemple des polystyrols ou des huiles d'esters à grosses molécules Comme huiles de base conviennent des fractions d'huiles minérales de vis- cosité faible convenablement raffinées ou des hydrocarbures synthétiques de poids moléculaires analogues.
Exemple.- On traite une fraction d'huile minérale ayant une viscosité de 15 est à 50 par environ 5% de terre de blanchiment, et on mélange le pro- duit ainsi purifié avec environ 20% d'une résine naturelle distillée en-des- sous de 10 mmo L'huile isolante de câble obtenue ayant une viscosité de plus de 1000 est à 50 , possède dans le domaine des températures normales un facteur de per- te diélectrique inférieur à 5.10-4. - -
