Definitions

  • the invention relates to a female electrical contact of the type comprising a plurality of metal fingers arranged parallel to each other according to the generators of a cylinder, in an assembly known as tulip contact.
  • Such contact is intended to cooperate with a male contact consisting of a tube, or a rod, cylindrical coaxial in female contact and moving coaxially.
  • Such tulip-type female contacts are known. in particular by document FR-A-9205689 and by document DE-A-2310129.
  • the latter describes a female contact comprising a first metal tulip provided with fingers metal contacts intended to cooperate with a male contact and separated from each other by insulating elements.
  • a first object of the invention is to provide a female contact in which the contact force is the same on all tulip fingers, even if the male contact penetrates axially offset.
  • Another object of the invention is to provide a female contact in which the deformation of fingers, due to the electrodynamic forces which are exercised on parallel fingers, either limited and does not exceed the limit of elastic deformation.
  • Another object of the invention is to provide a female contact in which, in the event of a short circuit, the risk of welding fingers to each other and of the pressure spring surrounding the contact fingers be removed.
  • This female contact in particular for high disconnector tension, comprises a first metal tulip provided with metallic contact fingers intended to cooperate with a male contact and separated from each other by insulating elements.
  • the contact female has a first tulip made by extrusion of a metal block followed by machining and insulating elements in the form of fingers carried by a second tulip, these fingers made of material insulation limiting movement of contact fingers in the radial direction and in the lateral direction to values predetermined values below the strain limit elastic of these contact fingers.
  • the female contact of the invention comprises two tulips, one conductive, the other insulating, interpenetrated.
  • Figure 1 shows the conductive tulip. It is produced by an extrusion of an aluminum block 1, completed by a machining operation. The extrusion makes it possible to produce substantially rectangular cross-sections with rounded edges, with a large face provided with a radial edge 2A with a flat top of height Y.
  • the choice of height Y is determined, in conjunction with the length X of the finger, to obtain rigidity contact finger.
  • the edge 2A extends from the bottom of the finger over all the length of the finger except the end of the finger.
  • a pad 3 of material resistant to wear and effects of the arch On the flat part of the end of the finger is reported a pad 3 of material resistant to wear and effects of the arch, and which has an inner protuberance 3A intended to cooperate electrically with the male contact.
  • the base of the block includes a threaded portion 5 allowing the fixing by screwing of a centering cone 7 for male contact 8 (see figure 3).
  • the cone 7 is provided icebreaker lugs 7A.
  • the extrusion made it possible to define, between each of the fingers, spaces 10 between which a tulip made of insulating material, produced by extrusion followed by machining or molding, and comprising a plurality of fingers 11 joined by bridges 12 to a portion cylindrical 13.
  • the insulating material can be chosen by example among the products known under the brands Teflon or GSM nylatron, the latter being a type 6 nylon with high resistance with a charge of molybdenum disulphide of which one of the characteristics is not to maintain the combustion.
  • the fingers 11 have a section which is substantially rectangular with rounded edges.
  • the insulating fingers 11 have the same length as the metal fingers 2.
  • the portion cylindrical 13 stops substantially at the thread 5. Between the end of the cylindrical portion 13 and the end fingers 11, bridges 12 define edges 11A to flat top.
  • the female contact which has just been described, solves the technical problems stated in the preamble to the present brief.
  • the presence of the insulating tulip ensures a substantially equal contact between the male contact and each pads 3, even if male contact occurs axially offset.
  • Insulating fingers not only limit bending metallic fingers but they keep them isolated the each other, which avoids welding problems between two parallel fingers deformed by the effect of a short circuit (effect of bringing together parallel currents, these effects being sensitive from around 80kA 1 sec. and 216 kA asymmetric peak 10 cycles).
  • the female contact can be fitted with a spring circular 15 to increase the contact pressure of the metallic tulip.
  • a spring circular 15 to increase the contact pressure of the metallic tulip.
  • the use of such a spring for the purpose above is a technique well known to those skilled in the art; however, the springs directly in contact with the metal fingers may experience a bypass current due to dynamic or thermal shocks during short-circuits, when one or more fingers are no longer in frank contact with male contact.
  • the spring 15 is arranged around the insulating tulip, which avoids any galvanic contact between the spring and the contact fingers metallic, the spring pressure force being transmitted through the insulating tulip. Maintaining the spring is provided by a groove machined in all insulating fingers 11.
  • the invention finds application in the equipment of high voltage disconnectors in which the movable hammer moves axially at the end of the closing operation.

Claims (7)

  1. Buchsenkontakt, insbesondere für Hochspannungstrennschalter, welcher ein erstes metallisches Gehäuse umfaßt, das mit metallischen Fingerkontakten (2) versehen ist, welche mit einem Stiftkontakt (8) zusammenwirken und voneinander durch isolierende Elemente getrennt sind, dadurch gekennzeichnet, daß er umfaßt:
    ein erstes Gehäuse, das durch Extrusion und anschließende Bearbeitung eines metallischen Blocks hergestellt wird und
    isolierende Elemente in Form von Fingern (11), die von einem zweiten Gehäuse getragen werden, wobei diese Finger aus isolierendem Material die Verschiebung der Fingerkontakte in radialer und in seitlicher Richtung gemäß vorbestimmten Werten, die unter der elastischen Verformungsgrenze dieser Fingerkontakte liegen, begrenzen.
  2. Buchsenkontakt gemäß Anspruch 1, dadurch gekennzeichnet, daß die Fingerkontakte des metallischen Gehäuses im Querschnitt die Form eines Rechtecks mit abgerundeten Rändern und eine Kante (2A) aufweisen, welche sich zumindest über einen Teil der Länge des Fingers erstreckt.
  3. Buchsenkontakt gemäß einem der Ansprüche 1 und 2, dadurch gekennzeichnet, daß die Finger aus isolierendem Material des zweiten Gehäuse dieselbe Länge wie die metallischen Fingerkontakte aufweisen.
  4. Buchsenkontakt gemäß einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß die Finger aus isolierendem Material des zweiten Gehäuses einen merklich rechteckigen Querschnitt mit abgerundeten Rändern aufweisen und eine Kante (11A) besitzen, die von einer der Längsseiten des Rechtecks ausgeht.
  5. Buchsenkontakt gemäß einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß die Länge der Fingerkontakte durch Einbringen einer Vertiefung (4) in den extrudierten Metallblock eingestellt wird.
