Definitions

  • the present invention relates to a disconnector usable in particular in high voltage, of the type comprising a socket outlet of the female type placed at one end of a first vertical insulating column, a hinged blade at one end of a second vertical insulating column and carrying at a first end a male contact intended to cooperate with said female contact, the movement of said blade being provided by a mechanism connected to an oscillating insulating column.
  • a disconnector of this type is described in English patent n ° 306,198.
  • the mechanism comprises a first lever articulated on the one hand to said blade and on the other hand to said oscillating column, a second lever articulated on the one hand to said blade and on the other hand to said second vertical insulating column, and a cam secured to said second vertical insulating column and cooperating with a roller disposed at the second end of said blade.
  • a first object of the invention is to produce a disconnector of the aforementioned type but of simpler construction.
  • Another object of the invention is to provide a disconnector whose operation is not disturbed by the presence of ice which would form either on the blade movement mechanism, or on the contacts.
  • Another object of the invention is to provide a disconnector using tulip contacts which have better short-circuit resistance than the jaw contacts.
  • a high voltage disconnector of the type comprising a socket of the female type placed at one end of a first vertical insulating column, an operating blade articulated at one end of a second vertical insulating column and carrying at a first end a male contact intended to cooperate with said female contact, the movement of the blade being ensured by a mechanism connected to an oscillating insulating column, characterized in that the articulation of said blade said second column is provided by means of two levers of unequal length each connected by a first end to a part integral with said second insulating column and by a second end at points distinct from said blade, said mechanism connecting the oscillating column and said blade comprising an arm articulated at one end to said oscillating column and at another end to said blade, said female contact being constituted by a tube with a substantially horizontal axis and split longitudinally over a part of its length to form contact fingers, said female contact being protected by a bell provided with ice-breaking lugs, said contact male having a
  • the reference 1 designates a metal beam constituting the upper part of the frame of a disconnector. This frame, produced in a conventional manner and not forming part of the invention, is not described in more detail.
  • a first vertical insulating column 2 carrying a protective cover 3 containing a female electrical contact 4, visible in detail in Figure 2, and consisting of a tube split longitudinally over part of its length so as to constitute contact fingers 4A arranged in the manner known as a tulip.
  • This female contact is intended to cooperate with a male contact which will be described later.
  • a spring 4B ensures the contact pressure.
  • the hood is open in the shape of a cone and has 4C icebreaker lugs and a 4D drip tray. Contact 4 is connected to a first socket 5.
  • the beam 1 also carries a second vertical insulating column 7 provided with a second outlet 8.
  • a vertical plate 9 provided with two points of articulation 10 and 11.
  • At the articulation 10 is connected to a first end of a first lever 12, the second end of which is articulated to one end 13A of a metal blade 13, the other end of which carries a male contact 13B cooperating with the female contact 4.
  • At the joint 11 is connected a first end of a second lever 14, the other end of which is articulated at a point 15 to the blade 13.
  • the male contact 13B is constituted by a tube having a bulged portion making it possible to ensure good contact pressure with the contact tulip.
  • a metal braid 16 electrically connects the socket 8 and the blade 13.
  • an oscillating insulating column produced in the form of an insulating part 20 of the same kind as columns 2 and 7, and articulated at its lower part around a fixed horizontal axis 21.
  • This column is provided with means not shown to allow it to perform oscillatory movements in a vertical plane, of amplitude not exceeding about twenty degrees around the vertical.
  • These means may for example comprise a rod fixed to the base of the column 20 associated with a mechanism for operating by traction on the rod.
  • the top of the column 20 carries a hinge 22 to which a first end of an arm 23 is hinged, the second end 24 of which is hinged to the blade 13.
  • the disconnector closing operation is obtained by carrying out the movements in the opposite direction.
  • the downward movement of the male contact below the horizontal, then its ascent, when the male contact approaches the female contact, makes it possible to break the ice that may have formed on the male contact, the latter coming up against the lugs 4C arranged at the input of the female contact.
  • the disconnector of the invention is of simple construction and consequently less expensive than the disconnects of the prior art.
  • the glass has less disadvantage than in the disconnectors of the prior art, since the entry of contacts are made horizontally and a protective cover can be used.
  • the invention applies to the production of high voltage disconnectors, from 25kV.

  1. Hochspannungs-Trennschalter der Art, der einen buchsenförmigen Stromanschluß (4) an einem Ende einer ersten senkrechten Isolatorsäule (2) und eine Betätigungslamelle (13) aufweist, die an einem Ende einer zweiten senkrechten Isolatorsäule (7) angelenkt ist und an einem ersten Ende einen Steckkontakt (13B) aufweist, der mit dem Buchsenkontakt zusammenwirken soll, wobei die Bewegung der Lamelle von einem Mechanismus gewährleistet wird, der mit einer schwenkbaren Isolatorsäule (20) verbunden ist, dadurch gekennzeichnet, daß die Gelenkverbindung der Lamelle (13) mit der zweiten Säule (7) mittels zweier Hebel (12, 14) ungleicher Länge gewährleistet wird, die je mit einem ersten Ende an einem mit der zweiten Isolatorsäule (7) verbundenen Teil (9) und mit einem zweiten Ende an unterschiedlichen Punkten (24, 15) der Lamelle angelenkt sind, wobei der die schwenkbare Säule (20) und die Lamelle (13) verbindende Mechanismus einen Arm (23) aufweist, der mit einem Ende an die schwingende Säule (20) und mit einem anderen Ende an die Lamelle (13) gekoppelt ist, wobei der Buchsenkontakt aus einem Rohr (4) besteht, dessen Achse im wesentlichen waagrecht liegt und das in Längsrichtung über einen Teil seiner Länge geschlitzt ist, um Kontaktfinger (4A) zu bilden, wobei der Buchsenkontakt (4) von einer mit Eisbrecherzapfen (4C) versehenen Glocke (3) geschützt wird, wobei der Steckkontakt einen verdickten Bereich (13B) aufweist, der sich zwischen die Finger (4A) schieben kann, wobei die Länge und die relative Anordnung der Hebel (12, 14) so gewählt werden, daß bei einer Öffnung des Trennschalters zunächst eine Bewegung der Lamelle gewährleistet wird, die eine waagrechte Komponente aufweist, die die Tendenz hat, den Steck- und den Buchsenkontakt zu trennen, sowie eine Komponente, die die Tendenz hat, das Ende der Lamelle unter das Niveau absinken zu lassen, das es aufweist, wenn der Trennschalter in der geschlossenen Stellung ist, wobei diese Bewegung von einer Schwenkbewegung der Lamelle um auf das Ende der zweiten Isolatorsäule (7) gefolgt wird.
