Definitions

  • the invention relates to an arc extinguishing plate assembly for a service switching device, in particular for a circuit breaker, a motor protection switch or a contactor, with parallel arranged arc quills made of ferromagnetic material having a V-shaped cutout on a narrow side edge, which forms an inlet region for the arc, and At least on one side at least partially coated with insulating material, according to the preamble of claim 1.
  • the invention relates to a service switching device with such an arc splitter stack.
  • a generic arc extinguisher arrangement also arc splitter stack or Deionblechun finds particular use in a circuit breaker or a motor protection switch or in a contactor by which not only rated currents, but also overcurrents and in particular short-circuit currents are to be turned off.
  • the mode of operation is such that an arc arising at a contact point at its opening is guided into the arc splitter stack due to the current forces in which the arc bases formed on the fixed or movable contact pieces are led via arc guide rails into the arc splitter stack, in which the arc is divided into several partial arcs is divided, whereby the arc voltage is increased and the short-circuit current thereby limited.
  • Such an arrangement is for example from the DE 103 12 820 known.
  • a problem with the movement of the arc or the individual partial arcs within the arc splitter stack is that without further action, the arc at the end of the arc splitter stack or at the side edges can overturn or re-ignite, so that a current limit and a correct short-circuit shutdown are prevented.
  • an arc quenching chamber having an arc quenching assembly whose arc quenching plates are coated with a gas or vapor emitting material. This material evaporates under the influence of the arc, which promotes arc quenching. But since the material is consumed, the number of feasible switching operations is limited.
  • an arc-quenching arrangement has been disclosed in which individual arc-quenching plates are coated with insulating material at least in the rear section viewed in the direction of the arc running, whereas other quenching plates located between the coated arc-quenching plates are uncoated.
  • the coated arc quenching plates are partially coated on both sides.
  • the object of the invention is to provide an arc extinguishing plate assembly, which leads to the known arrangements to improve the extinguishing and switching properties, with flashbacks or flashovers outside of the splitter stack prevented by the stabilization of the arc in the focal spot become. A flashover between the sheets is avoided and a local melting of individual sheets is prevented.
  • each arc quenching plate there is a region behind the inlet region, seen in the direction of arc travel, which is free of the insulating material, the insulating material completely surrounding the free region (19, 20, 35, 35a).
  • an island-like area or an island-like zone is left uncoated on each plate, into which uncoated zone the arc is intended to be guided in a targeted manner and should preferably burn in the area of the uncoated zone. He can oscillate in the uncoated area, and by oscillating a local melting can be prevented.
  • a further preferred embodiment of the invention may be that the area not covered by the insulating material is thus coated with a conductive material, which may be silver, for example.
  • the insulating coating may have gas or vapor-releasing properties upon arc action; This promotes the current limitation.
  • An electrical circuit breaker which is not to be shown here in detail, but whose structure is known as such, has a contact point with a fixed and attached to a contact lever movable contact piece, each associated with arc runners, which run parallel and an arc splitter stack according to the FIGS. 1 to 7 between them. That such a circuit breaker has a switch lock, a toggle, a thermal and electromagnetic release and terminals, a toggle and a mounting option on a hat profile support rail, will not be described here.
  • the arc splitter stack is constructed of a plurality of arc quenching plates, which may be formed as in the FIGS. 1 to 3 shown.
  • each arc quenching plate 10 of an arc splitter stack has an elongated rectangular shape, wherein in the region of in the Fig. 1 Lower drawn first narrow side edge 11 a symmetrical, V-shaped cutout 12 is introduced, which tapers to the opposite lying second narrow side edge 13, so that the V-shape to the first narrow side edge 11 is open.
  • a slot-shaped portion 14 whose side edges 15 and 16 are perpendicular to the narrow side edges 11 and 13; this slot-shaped cutout 14 or slot 14 ends approximately in the third, which is adjacent to the second narrow side edge 13 and connects thereto.
  • the arc splitter stack is on both sides with a layer 17 and 18 of insulating material, except for a remaining free portion 19 and 20, in the embodiment according to Fig. 1 circular and arranged in extension of the central axis of the V-shaped cutout 12 and the slot 14, coated.
  • Fig. 4 illustrates this with reference to a sectional view along the section line IV-IV of Fig. 1 ,
  • the Fig. 5 shows a sectional view along the section line VV of Fig. 1 with three arc quenching plates 10a, 10b and 10c, with insulating material 17a, 18a; 17b, 18b and 17c and 18c are coated.
  • the uncoated areas 19a, 20a; 19b, 20b and 19c and 20c are aligned with each other and lie on an axis which is perpendicular to the arc extinguishing plates 10a, 10b, 10c.
  • each arc flash plate 30 has at its first narrow side edge 31 a cutout 12 corresponding cutout 32, to which a slot-shaped cutout 33 connects, based on the central axis of the elongated rectangular arc extinguishing plate 30, which central axis perpendicular to the first narrow side edge 31 and a second narrow side edge 34th runs approximately centrally, is angled at an acute angle ⁇ .
  • the angle is angled to the right
  • the arc splitter plate 30a by 180 ° about the central longitudinal axis MM (see Fig. 2 ) is twisted, so that there is the slot-shaped portion 33a angled to the left.
  • This type of arc splitter package construction is mainly used in switching devices for DC voltage.
  • the arc splitter differs according to Fig. 2 from the according to Fig. 3 in principle not, it is used in an arc splitter stack, however, each rotated by 180 °.
  • the arc extinguishing plates 30 according to Fig. 2 or the arc quenching plates 30a according to Fig. 3 are each installed in one embodiment of an arc splitter stack in this so that the individual slots are parallel to each other.
  • the arc extinguishing plates 30 according to Fig. 2 and the arc quenching plate 30a of FIG Fig. 3 are covered by an insulating material, which corresponds to the insulating material or the layers 17, 18.
  • an insulating material which corresponds to the insulating material or the layers 17, 18.
  • an area 35 or 35a which is uncoated, as the section 19, 20.
  • the arc is about the V-shaped cutout 32 in the slot 33rd run in and from there to the area 35, 35a skip and burn stable in this uncoated area.
  • FIG. 6 shows the embodiment of the arc splitter stack from above
  • Fig. 7 shows a sectional view of this arc splitter stack according to the section line VII-VII of Fig. 6
