Definitions

  • the invention relates to an electrical installation device with arc Vorschraum, arc guide rails and current-limiting arc quenching device according to the preamble of claim 1.
  • the invention can be used for example in circuit breakers and motor protection switch.
  • Miniature circuit breakers and motor protection switches are used in the event of a fault to disconnect electrical lines that are loaded with high current overcurrents from the supply network.
  • a fixed and a movable contact piece are provided in an arc Vorschraum, which are connected to the respective terminals.
  • a switching arc which is deleted in a quenching device provided for this purpose.
  • the drawn arc commutes from the opened contact pieces on arc guide rails, and then subdivided into an arc splitter stack (Deion quenching chamber). There, a high arc voltage is generated to limit the current, so that the arc goes out.
  • an arc extinguishing arrangement for an electrical switching device which has a quenching chamber (in the case of a switching operation between a fixed and a movable contact piece, an arc is generated) and a plurality of arc quenching exhibiting arc splitter stack comprises, in which the arc is guided over guide rails.
  • a quenching chamber in the case of a switching operation between a fixed and a movable contact piece, an arc is generated
  • a plurality of arc quenching exhibiting arc splitter stack comprises, in which the arc is guided over guide rails.
  • Inside or outside of the arc extinguishing package at least one plate of insulating material - an insulating plate - is arranged, whose outer periphery does not project beyond the outer periphery of the arc extinguishing plates and which has an inner recess.
  • the invention has for its object to provide an electrical installation device with arc pre-chamber space, arc guide rails and current-limiting arc quenching device of the type mentioned above, which allows optimal mounting option of the insulation.
  • the achievable with the present invention consist in particular that different types of arc quenching can be used together with the same insulating, d. H. it is not necessary to integrate the insulating plate in a special and thus costly arc quenching device itself. Also, it is not necessary to form the insulating plate as part of the housing itself, d. H. it is Z. As well as the use of a thermoset for the housing possible (the insulating itself is preferably formed from a gassing thermoplastic). With regard to the selection of the thickness of the insulating plate or the material, there are no restrictions, the selection is made exclusively from the point of optimum arc extinction. In this way, the switching capacity can be improved and the turn-off behavior stabilized. The insulating plate can be mounted in a very simple manner. Overall, there are cost advantages compared to known embodiments.
  • an insulating plate 20 is provided with a recess 21 and an end side (integrally formed) mounting bracket 22, said mounting bracket 22 engages U-shaped around the end portion of the arc guide rail 14, whereby a latching attachment of the insulating plate 20 at the Component of electromagnetic release 9 / fixed switching contact piece 4 / arc guide rail 14 is effected.
  • the directed to the arc Vorschraum 7 "input side" portion of the insulating plate 20 engages under the arc horn 15, whereby an additional support of the insulating plate 20 is effected.
  • the electromagnetic release 9 with the armature 10 and the bimetallic strip 11 can be seen.
  • the insulating plate 20 (including integrally molded mounting bracket 22) together with an antechamber plate 23 as one piece Component made of a gassing plastic, which advantageously at the same time in the attachment of the insulating plate 20 by means of the arc guide rail 14 gripping mounting bracket 22, a fastening of the pre-chamber plate 23 results.
  • this embodiment is very easy to install and has a reduced number of parts. Ultimately, this results in cost advantages.
  • the insulating plate 20 or the insulating plate halves 25 + 26 brings about an improvement in the stable burning of the arc 13 within the arc quenching device 12 (stabilization of the arc base point after the inlet into the arc quenching device) . cause.
  • the recess 21 of the insulating plate advantageously does not have to be adapted to the recess of the individual quenching plates of the arc splitter stack. Rather, the recess 21 is chosen so that an optimization with respect to the quenching behavior of the arc 13 sets.
