Definitions

  • the invention relates to an arc extinguishing device according to the preamble of claim 1.
  • switching contacts When switching contacts are actuated in electrical switching devices, when the contact point is opened, d. H. when the contact pieces are pulled apart, a switching arc, the size and intensity of which increases with higher current intensity. Switching arcs of this type are intended to quickly commutate from the contact pieces and be extinguished in a quenching device provided for this purpose.
  • An arc quenching device has become known from EP-A 0 164 632, in which a quenching plate stack formed from stacked quenching plates is arranged laterally and rearwards, ie. H. on the end face of the quenching sheet stack opposite the contact point, is enveloped by walls.
  • the side walls are fixed by means of molded lugs on the extinguishing plates, which engage in recesses provided for this purpose in the side walls, while the rear wall adjoins the length of the side walls, which protrude from the stack of extinguishing plates.
  • cutouts are provided at the top and bottom, which serve as ventilation for the exhaust air.
  • the arrangement of the quenching plates in the quenching plate stack is determined in accordance with the recesses in the side walls, in which the retaining lugs of the quenching plates engage.
  • the extent of the extinguishing device in the longitudinal direction is determined by the length of the side walls, so that the use of this extinguishing device is only possible in switchgear specially prepared for this.
  • an arc extinguishing device of the type mentioned at the outset has become known, in which several arc extinguishing plates are arranged one above the other, which are kept at a distance by means of lateral wall parts and by means of which the arc extinguishing plate packet is held together to form a unit.
  • the side wall parts are located on the side of the arc quenching plate package opposite the contact point, which is why the side wall parts serve solely and exclusively for spacing the arc quenching plates and must be designed for this purpose.
  • the rear wall part, which is provided with holes, is smooth on the side surface facing the arc-quenching plates.
  • the object of the invention is to provide an extinguishing device of the type mentioned at the outset which is simple and space-saving and which can be produced inexpensively with regard to a wide range of possible uses.
  • the quenching plates are inserted into the grooves and the webs serve as spacers between the individual quenching plates, so that the arc quenching plate package is held on the one hand by the side wall parts and on the other hand by the rear wall part.
  • the arc quenching plates together with the side wall parts and the rear wall part thus form a unit which can be used together in the arc quenching chamber. Due to the matching of the width of the grooves to the thickness of the quenching plates, the rear wall part is held on the arc quenching plate package after the quenching plates have been pushed into the grooves.
  • the rear wall part should consist of a material which, under the action of an arc, develops gas which cools the arc.
  • An arc chamber in which gas-emitting material is provided in the areas in which the arc burns, has become known, for example, from DE-A 2 217 031.
  • FIG. 1 shows an extinguishing device 10 with a fire-extinguishing sheet stack 12, a rear wall part 14 and a side wall part 16.
  • the fire-extinguishing sheet stack 12 is formed from individual fire-extinguishing sheets 20 which are arranged one above the other in parallel.
  • the side edges 22 of the extinguishing plates 20 visible in FIG. 1 have retaining lugs 24, 26 which engage in retaining openings 25, 27 in the side wall part 16 in a positive and non-positive manner.
  • the holding openings 25, 27 in the side wall part 16 are arranged offset to one another, so that two holding openings 27 are located next to one another in one plane and only a single holding opening 25 in the plane above it.
  • the rear wall part 14 On one end face of the quenching plate stack 10, the rear wall part 14 is arranged, which has grooves 28 which are separated from one another by webs 30.
  • the individual quenching plates 20 of the quenching plate stack 12 are inserted into the grooves 28 of the rear wall part 14 and kept apart by the webs 30.
  • With 21 a bevel of the side edges is shown, which facilitates the handling of the extinguishing plates 20 when inserted into the grooves 28 of the rear wall part 14.
  • FIG. 2 shows the view of a rear wall part 14 in which grooves 28 and webs 30 alternate with one another.
  • Rectangular recesses 32 which are located in the region of the webs and are offset from web 30 to web 30 and arranged one above the other in two parallel rows 31, can be seen clearly at a short distance from the two lateral longitudinal edges of the rear wall part.
  • the recesses which serve as ventilation openings 32 for the discharge of the exhaust air generated during the burning of an arc, are alternately 30 times on the web 30 to the next web one and then arranged on the other side of the rear wall part 14.
  • each web 30 is provided with a vent opening 32, which is arranged laterally offset from that of the adjacent web 30.
  • This design and arrangement of the rear wall part 14 ensures that the arc inlet is only minimally adversely affected compared to the rearwardly open arrangement. Furthermore, to reinforce the arc cooling, it is provided according to the invention to manufacture the rear wall part from gassing material, that is to say from a material which, under the action of the arc, causes pressure build-up in the arc quenching chamber and intensive cooling of the arc, which supports the quenching effect.
  • FIG. 3 shows a longitudinal section through a rear wall part 14 in accordance with the section line I-I shown in FIG.
  • the grooves 28 and the webs 30 can be clearly seen, which are pierced by ventilation openings 32. It is clear from this illustration that the ventilation openings 32 are arranged alternately on the rear wall part 14.
  • FIG. 4 shows a cross section through a rear wall part 14 according to FIG. 2 in accordance with the section line II-II given there. Accordingly, the section runs through a web 30, so that the majority of the illustration in FIG. 5 has hatching.
  • the vent opening 32 interrupts the course of the web 30 and, at the same time, provides a view of the adjacent web 30 in this illustration.
  • FIG. 5 shows a single fire-extinguishing plate 20 which has on its longitudinal edges 22 the bevels 21 already mentioned and parallel-shaped indentations 34, in which retaining lugs 24, 26 are formed and which serve to accommodate the lateral band parts 16.
  • an edge-parallel indentation 34 is provided with a retaining lug 24, which is arranged approximately halfway along the length 36 of the indentation 34.
  • the opposite edge-parallel indentation 34 is provided with two retaining lugs 26, which are each arranged approximately at a quarter and at three-quarters of the length of the edge-parallel indentation 34.
  • the front end edge 35 of the quenching plate 20 facing the contact point is provided with a parabolically shaped recess 38, the recess of which Depth is approximately half the length of an extinguishing plate 20 and at the apex there is a further, but also smaller, parabolic recess 39.
  • the depth of the second recess 39 is approximately 1/6 of the depth of the first recess 38.
  • FIG. 6 shows the top view of an extinguishing device according to the invention, in which both the side wall parts 16 inserted into the parallel-parallel recesses 34 can be seen with the retaining lugs 24, 26 penetrating through them, and also the rear wall part arranged on the back of the quenching plate package 12 14.
  • the front-side recesses 38 and 39 can also be seen, which are facing the arc which arises in the contact point.
  • the inventive design of the extinguishing device 10 allows the arrangement of the extinguishing plates 20 to each other in a simple and inexpensive manner, i. H. adapt both their distance and their thickness to the respective application-related requirements in a manner appropriate to the application, since only the quenching plate package 12 formed from the quenching plates 20, the side retaining strips 16 and the rear wall part 14 is subject to possible changes.
  • the distance between the quenching plates and thus the respective voltage of the individual arcs can be changed by omitting every second quenching plate.
