Description
Isolateur comprenant un écran intérieur à potentiel commandé La présente invention concerne un isolateur com prenant un écran intérieur à potentiel commandé noyé dans la masse isolante moulée constituant le corps de l'isolateur.
L'invention a pour but de fournir un isolateur comprenant un dispositif de contact permettant de mettre à la terre ledit écran. Cet isolateur est caracté- risé en ce que ledit dispositif de contact est constitué par un pointeau coulissant dans une douille en métal sous l'action d'un ressort prenant appui sur le fond de la douille, la douille étant raccordée à l'écran dont le potentiel est à commander et noyée avec l'écran dans la masse isolante. Le pointeau coulissant peut ainsi établir le contact avec un conducteur passant à proximité immédiate de l'isolateur.
Une forme :d'exécution de l'isolateur, selon l'in vention, est représentée, à titre d'exemple, au dessin annexé.
L'unique figure de ce dessin représente une partie d'une coupe axiale d'un isolateur de traversée dans lequel est noyé un dispositif de contact relié à un écran .intérieur. Sur .cette figure, l'isolateur de tra versée comprend deux cônes d'isolateur 1 et 2 et un bourrelet annulaire de fixation 3. Dans l'axe de l'iso lateur passe un conducteur 4 et, en regard du bour relet annulaire de fixation 3, est disposé un écran intérieur 5 qui doit être mis à la terre. Cet écran 5 est relié par soudure à une douille 6 noyée dans le bour relet 3 et dans laquelle coulisse un pointeau 7 sous l'action d'un ressort 8 prenant appui sur le fond de la douille 6.
Le pointeau 7 est pressé par le ressort 8 contre un anneau de fixation 9 vissé sur la paroi 10, traversée par l'isolateur. Entre le bourrelet 3 et la paroi 10 est disposé un joint 11. L'avantage du con tact de mise à la terre est particulièrement sensible lorsque le contact doit être assuré à travers une pièce conductrice dont la position par rapport à l'isolateur peut varier légèrement, comme c'est le cas lors de la fixation par un anneau.
Insulator comprising an internal screen with controlled potential The present invention relates to an insulator comprising an internal screen with controlled potential embedded in the molded insulating mass constituting the body of the insulator.
The object of the invention is to provide an insulator comprising a contact device making it possible to ground said screen. This insulator is characterized in that said contact device is constituted by a needle sliding in a metal sleeve under the action of a spring bearing on the bottom of the sleeve, the sleeve being connected to the screen of which the potential must be controlled and embedded with the screen in the insulating mass. The sliding needle can thus establish contact with a conductor passing in the immediate vicinity of the insulator.
One embodiment of the insulator, according to the invention, is shown, by way of example, in the accompanying drawing.
The only figure in this drawing shows part of an axial section of a feed-through insulator in which is embedded a contact device connected to an interior screen. In this figure, the feed insulator comprises two insulator cones 1 and 2 and an annular fixing bead 3. In the axis of the insulator passes a conductor 4 and, opposite the annular bead of fixing 3, there is an internal screen 5 which must be earthed. This screen 5 is connected by welding to a sleeve 6 embedded in the relet ring 3 and in which a needle 7 slides under the action of a spring 8 bearing on the bottom of the sleeve 6.
The needle 7 is pressed by the spring 8 against a fixing ring 9 screwed on the wall 10, through which the insulator passes. Between the bead 3 and the wall 10 is disposed a seal 11. The advantage of the earthing contact is particularly noticeable when the contact must be made through a conductive part whose position relative to the insulator can vary. slightly, as is the case when fixing with a ring.
