Definitions

  • the invention relates to an arc quenching device for an air switching low voltage switchgear, with a Extinguishing plates having extinguishing space and with a the Extinguishing chamber covering, with outlet openings for switching gases provided with a lid, as well as with an optionally usable separate, Deionizer having cooling device for the switching gases.
  • each Arc quenching chamber generally contains a variety arranged between two side walls quenching plates, the contribute to the cooling and extinguishing of the arc. Above There is a lid with discharge openings on the quenching plates for switching gases.
  • the installation locations of low-voltage circuit breakers can be very different. It depends on which temperature and what degree of ionization from the arc quenching devices may have exiting switching gases. To take these different conditions into account, become arc quenchers in a normal design manufactured for standard requirements at Needed by a separate cooling device for the switching gases can be supplemented. It may happen that There is a need for improved cooling of the switching gases only after the establishment of a switchgear turns out, z. B. due to a changed mode of operation or due to the Use of other consumers with the result that it is too Circuits with higher power and a correspondingly larger Quantity of switching gases comes.
  • the additional cooling device from an essay for each of the extinguishing chambers of a Circuit breaker has a frame-like Housing body and disposed therein deionization in the shape of wire mesh, perforated plates or the like.
  • the Advantage of the simple subsequent attachment of such separate cooling device faces the height of the circuit breaker by the separate cooling device is enlarged. Therefore, the case may occur that separate Do not attach cooling equipment later, because the space required in a switch cell not to Available.
  • the object of the invention is based on an arc quenching device according to DE 35 41 514 C2 therein, a Arc quenching device with a mountable on demand additional cooling device to create the volume of construction of the circuit breaker is not increased.
  • the separate cooling device for receiving the Deionizing agent like a frame and for installation in the interior the arc quenching device between the quenching plates and the cover is suitably formed, wherein the quenching plates and the lid by common parallel insulating walls are supported.
  • the cooling device by a Cover plate and a bottom plate added to a cartridge insert be that a cavity for introducing the deionization forms, wherein in the cover plate and the bottom plate Passage openings are provided for the switching gases.
  • the cooling device receives a for if desired, retrofitting cheap design.
  • this design offers the possibility of cooling effect regardless of, for example, in the form of metal fabrics or metal screens provided deionization to influence. This can be done by that the passage openings a circular or polygonal Have cross section or in that they slit are formed.
  • this form-fitting are suitable Fastening means, for. B. in such a way that the fastening means as receiving openings in the lid of the arc quenching device and as on the cover plate of the insert cassette arranged and for insertion into said receiving openings certain fastening pins are formed.
  • the dimensions of the receiving openings are and the mounting pin so matched, in that when inserting the fastening pins into the receiving openings a frictional connection for securing against slipping out consists. This can be effected by the fixing pins slotted to produce the frictional connection and are resilient.
  • the fastening means for the cooling device can also as moldings and outgoing therefrom guide rails for inserting the cooling device designed as a cartridge insert be educated.
  • Fig. 1 shows a perspective view, partially in Section, an embodiment of an arc quenching device according to the invention.
  • Fig. 2 shows a perspective view of a first embodiment a lid for an inventive arc quenching device.
  • Fig. 3 shows a perspective view of a first embodiment an insert cassette for an inventive Arc quenching device.
  • FIG. 4 shows a perspective view of another Embodiment of a lid for an inventive Arc quenching device.

  • Fig. 2 shows a perspective view of a first advantageous Embodiment of a lid 8 for an inventive Arc quenching device 1. It has outlet openings 9, a passage opening 14 for a not shown Fixing screw, formations 11 with laterally arranged thereon projecting webs 12, for engaging in Slots 13 of the insulating walls 2, 3 of the splitter stack 7 and Receiving openings 15, 16, 17, 18, in which mounting pins 19, 20, 21, 22 (Fig. 3) are insertable.
  • the in itself for receiving the protruding webs 12 serving formations 11 have a triangular cross-section such that they when introducing the insert cassette 10 form a guide.
  • Fig. 3 shows a perspective view of a first embodiment an insert cassette 10 for an inventive Arc quenching device 1. It consists essentially from a cover plate 23, a bottom plate 24 and side walls 25, 26, which has a cavity for inserting metal screens 27 form as a deionizing agent. In the cover plate 23 and the bottom plate 24 are in the flow direction of the Switching gases passage openings 28; 29 provided, the one have circular cross-section. Furthermore, at the Cover plate 23 mounting pins 19, 20, 21, 22 arranged, in the assembly of the insert cartridge 10 in the receiving openings 15, 16, 17, 18 of the cover 8 of the arc quenching device be introduced as the dash-dotted Arrows is indicated.
  • FIG. 4 shows a perspective view of another Embodiment of a lid 30 for an inventive Arc quenching device 1. It has outlet openings 31, a passage opening 32 for a fastening screw, not shown and moldings 33 arranged laterally therewith projecting webs 34 for engaging in slots 13 of the insulating walls 2, 3 of the arc splitter stack 7.
  • the projections 33 for receiving the projecting webs 34 formed in the form of guide rails 35, 36, in which the insert cassette 37 (Fig. 5) is inserted.
  • Fig. 5 shows a perspective view of another Embodiment of an insert cassette 37 for an inventive Arc quenching device 1. It consists essentially from a cover plate 38, a bottom plate 39 and side walls 40, 41, which has a cavity for inserting metal screens Form 42 as a deionizing agent.
  • cover plate 38 and the bottom plate 39 are in the flow direction of the Switching gas passage openings 43, 44 provided in this Embodiment are slit-shaped.
  • the insert cartridge according to the invention is very simple if necessary to mount and does not cause enlargement of the Construction volume of the circuit breaker.
