Description
Borne de traversée du type condensateur La présente invention a pour objet une borne de traversée du type condensateur, com prenant un manchon en matière moulée.
Dans une telle borne de traversée, il est dangereux de prévoir dans le manchon en ma tière moulée un cylindre métallique lui confé rant la propriété d'électrode condensateur, car il en résulte des tensions internes, lors des échauffements par exemple, pouvant produire des fissures.
La borne de traversée suivant l'invention est caractérisée en ce que l'effet de capacité est obtenu au moyen d'une électrode constituée par une toile métallique en forme de cylindre insérée dans le manchon.
La figure du dessin annexé représente, à titre d'exemple, une forme d'exécution de la borne de traversée faisant l'objet de l'inven- tion.
L'enveloppe à traverser d'un appareil élec trique est désignée par E. La borne de traversée comprend un manchon M en matière moulée traversé par une tige conductrice T. L'effet de capacité est obtenu au moyen d'une électrode t constituée par une toile mé tallique, en forme de cylindre entourant la tige T, et insérée dans le manchon M.
L'électrode t est reliée par un conducteur c à une douille métallique a entourant un des boulons d'assem blage de la borne à l'enveloppe E de l'appareil électrique. L'électrode t est donc reliée de cette façon à la masse de l'appareil.
Lors d'échauffements éventuels, la toile métallique constituant l'électrode t peut se di later avec le manchon M, sans y créer de ten sions dangereuses.
A capacitor-type feed-through terminal The present invention relates to a capacitor-type feed-through terminal, comprising a molded material sleeve.
In such a feed-through terminal, it is dangerous to provide a metal cylinder in the molded material sleeve giving it the property of a capacitor electrode, since this results in internal stresses, during heating for example, which can produce cracks. .
The feed-through terminal according to the invention is characterized in that the capacitance effect is obtained by means of an electrode constituted by a metallic wire in the form of a cylinder inserted in the sleeve.
The figure of the appended drawing shows, by way of example, an embodiment of the feed-through terminal forming the subject of the invention.
The casing to be passed through an electrical device is designated by E. The feed-through terminal comprises a sleeve M of molded material traversed by a conductive rod T. The capacitance effect is obtained by means of an electrode t constituted by a wire mesh, cylinder-shaped surrounding the rod T, and inserted into the sleeve M.
Electrode t is connected by a conductor c to a metal sleeve a surrounding one of the bolts connecting the terminal to the casing E of the electrical apparatus. The electrode t is therefore connected in this way to the ground of the device.
In the event of possible heating, the metal mesh constituting the electrode t can expand with the sleeve M, without creating dangerous voltages therein.
