Definitions

  • the invention relates to a burnup circuit arrangement especially for circuit breakers, as used in power plants, Substations and other facilities of the Electric power supply for switching on and off of Operating and overcurrents are used.
  • the invention is based on the object, a Abbrandschaltanowski indicate which one not by limited the material properties of the contact fingers Burn-up reserve has.
  • the burnup circuit arrangement shown in FIG. 1 has as first contact piece with a first electrical Connection connected contact tulip, which consists of several um arranged a switching axis 1 and with the same one Angle of approx. 30 ° including contact fingers 2 which is entirely or at least in the area of Abbrandkmü of burn-resistant material such. W / Cu, Graphite, CFC, graphite / Cu, CFC / Cu.
  • a solid switching pin 3 which is also made of burn-resistant material existing tip 4 has. He is, for. B. over a Sliding tulip or a flexible pipe, with a second connected electrical connection and by means of a (not shown) switching drive along the switching axis. 1 between a switch-on, in which him the Touch contact finger 2 on its outside and one Off position, in which he is spaced from the same, displaceable.
  • each contact finger 2 connects the same a preferably welded to him supply line which makes it electrically conductive with a housing part. 5 and continues to connect to the first electrical connection. It is each formed by a band 6, which consists of several superposed strips of flexible electrically conductive material, for. B. of copper or a Consists of copper-containing alloy.
  • Connecting portions 7, which in the direction of Contact fingers 2 connect directly to the same are the bands 6 respectively by press-welding the strips stiffened. Otherwise, the stripes are not firm connected to each other, so that the band 6 each from the outer end of the connecting portion 7 is flexible.
  • a leaf spring 8 presses in each case from the outside elastically against the connecting portion 7, so that the contact finger 2 in the closed position is pressed against the switching pin 3.
  • a support body 9 made of electrically insulating material forms a frustoconical outwardly facing Support surface 10, at which in the off position below the action of the leaf springs 8 to a small extent the Contact fingers 2 and to a considerable extent over the Connecting portion 7 extending part of the bands 6 with rest against their insides. Furthermore he makes himself an in Turning in direction expanding central nozzle 11, in which in the closed position of the switching pin 3 protrudes.
  • the Angle of the support surface and thus also the upper limit of the Angle of the contact fingers with the switching axis chosen differently become.
  • it is between 15 ° and 45 °, the Switching axis taken in the switch-on direction.
  • the contact pieces can also be supplemented by other ingredients, eg. B. in each case a Abbrandring be provided, which of the Contact tulip or in the off position the switching pin is upstream or it can only be on one side be arranged such Abbrandring.
