Definitions

  • the invention relates to a quenching coil according to the arc-rotation principle for use in gas-insulated, in particular SF 6 gas-insulated load disconnectors or circuit breakers for switching off currents in medium-voltage switchgear.
  • the bobbin of the quenching coil consists of a non-magnetic material and the Winding usually made of a copper tape with a film insulation (foil tape) between the band layers, wherein the beginning of the copper strip, preferably by soldering, riveting or screws is mechanically and electrically connected to the bobbin.
  • the Copper tape winding is characterized by a with the copper band end electrically contacted clamping element, usually a clamp, held together.
  • the quenching coil is expensive because its mounting, including the attachment of the two Ends of the winding, consuming and without pressing tool is not feasible. moreover the coil core is reduced by the introduced radial gap in its strength.
  • the invention is that in a quenching coil, a metallic, cylindrical Spool, a winding of an electrically conductive metal and an insulation between having the winding layers, wherein the beginning of the winding on the bobbin fixed and electrically contacted with this and the winding by a with the Winding end electrically contacted clamping element is mechanically held together, the beginning and an immediately following part of the first winding layer flat and blank rests on the bobbin and this part only by the outer clamping element and the pressure generated by this on the winding mechanically and electrically fixed with is connected to the bobbin.
  • This coil construction in which a complex connection technology for fixing the beginning of the winding on the bobbin by rivets, screws or by soldering, ensures the mechanical strength of the bobbin, so that this also withstands high mechanical stress caused by high currents. moreover also damage to the winding by screws or rivets is avoided, so that the arc rotation is unimpaired.
  • half the first winding layer can be bare rest on the bobbin. Also, the last half winding can be wound back.
  • a metallic band for example a clamp made of steel, which are wrapped around the winding and by screwing elements is tightened, whereby the winding with the insulation, preferably a Isolierfolienband compressed and a sufficient mechanical and electrical contact pressure are generated.
  • the beginning of an insulating foil tape is interposed and then wound up this and the other winding layers.
  • the other winding layers are repulsed part of the last winding layer and then the metallic band (steel clamp) placed around the winding, tightened and thereby compressed the winding.
  • the extinguishing coil shown in Fig. 1 has a bobbin 1, a arranged on this Wrapping 2 of copper tape with several tape layers, of which only two layers shown are, between a part of the first band layer 2a and the bobbin 1 and between the band layers arranged plastic film 3 for insulation and a clamp 4 steel with a screw 5 on, through which the winding 2 on the bobbin 1 is pressed.
  • the foil insert between the first band layer 2 a and the bobbin 1 begins after the first half band layer 2a, which rests bare on the bobbin 1, and ends after the last band position 2b. This is half repulsed, with the folded back half bare on the other half of the last band layer 2b rests.
  • Figs. 2 and 3 the beginning and the end phase of the tape winding are shown.
  • the first band layer 2a is, for example, with an adhesive tape strip (not shown) fixed on the bobbin 1.
  • the first band layer 2a is half (approx. 180 °) blank in winding direction A wound.
  • the last band layer 2b is halfway up (about 180 °) the winding back over the film 3 (winding direction B in Fig. 3).
  • E On the after outside bare winding, whose end is denoted by E, eventually becomes the clamp 4 arranged.
  • the 4 is a three-position power switch with a metallic contact blade 11, a fixed contact 12 and the extinguishing coil 1 according to the invention. That the switching contact forming contact blade 11 is about an axis S between the fixed contact 12 and a ground potential contact, not shown, pivotally mounted. On the contact blade is articulated a connecting rod 14, which via a (not shown) rocker arm of a (Also not shown) switching shaft is actuated. The contact blade 11 has at its free end of a corresponding to the fixed contact 12 contact surface 18.
  • the Contact surfaces are formed in a plane perpendicular to the pivot axis S.
  • the contact surface 18 is designed high-temperature resistant to the thermal stress of the arc to be able to withstand.
  • Fig. 1 is a view of the quenching coil in the direction of arrow An.
  • the clamping elements the winding 2 are indicated by the reference numeral 5.
