Definitions

  • the present invention relates to a contact arrangement for NH fuse switch disconnector, NH fuse load switch strips or the like with a contact tulip for receiving a knife NH fuse and contact protection for the contact tulip, which with an opening for performing the safety knife and adjacent to this opening with molded extinguishing plates is provided as an arc extinguishing agent.
  • Such contact arrangements are known and also in practical use. They can be single or multi-pole.
  • the NH fuse is attached to the underside of a switch cover which is pivotally mounted on the circuit breaker or the load switch bar or by parallel guides.
  • a switch cover which is pivotally mounted on the circuit breaker or the load switch bar or by parallel guides.
  • extinguishing chambers are known as extinguishing agent on such contact arrangements, which are provided with a plurality of approximately U-shaped and stacked at a mutual distance stacking plates. From their extinguishing effect, the extinguishing chambers are superior to the extinguishing plates. From their construction, however, they are much more expensive and expensive than extinguishing plates, which can be obtained simply as molded ribs in the production of contact protection as a plastic injection molded part without any additional effort.
  • NH fuse switch disconnectors NH fuse switch disconnectors or the like
  • Devices in which contact arrangements of the type considered are used are usually designed for a specific switching capacity according to IEC 60947-3.
  • a standardized switching capacity is, for example, AC22 at 690V.
  • Another normalized switching capacity is AC 23 at 690 V. Due to the limited extinguishing effect of extinguishing plates, contact arrangements of the type mentioned in the introduction are only used in practice up to the aforementioned switching capacity of AC22. For larger switching capacities, such as those mentioned by AC23, contact arrangements with extinguishing chambers are used.
  • a contact arrangement is provided, which can be easily adapted to the above-mentioned different circumstances by merely on-demand mounting a quenching chamber on the standard existing extinguishing plates.
  • the invention reduces the variety of types of NH fuse switch disconnectors, NH fuse switch-disconnectors or the like, which also has a favorable effect on the storage.
  • Another advantage of the invention is the fact that the combination of extinguishing plates and quenching chamber even better extinguishing properties than the parts mentioned each alone.
  • the quenching chamber comprises, in a manner known per se, an insulating material housing into which the quenching plates, in particular those of a U-shaped design, are inserted and held therein by guides.
  • the extinguishing plates advantageously engage between the legs of the U-shaped extinguishing plates in the extinguishing chamber.
  • the extinguishing chamber in the plugged state can be determined in particular by a snap connection.
  • a knock-out opening can be provided between the extinguishing plates and / or a knock-out opening can be provided in the contact protection area in the attachment area of the extinguishing chamber.
  • extinguishing plates and extinguishing chamber should be dimensionally and dimensionally adapted to each other.
  • the properties of the contact device according to the invention can be further improved by providing two, preferably slightly resilient, guide ribs as insertion aids for the safety knife into the contact tulip on the underside of the contact protection facing the Kontkattulpe.
  • these guide ribs can be obtained without additional effort in the formation of contact protection as a plastic injection molded part by simply spraying.
  • By mediated by the guide ribs centering of the safety knife this hits when switching virtually simultaneously on both legs of the contact tulip, whereby the contact bounce and the associated burnup are greatly reduced.
  • means are formed on the contact arrangement, which ensure a targeted discharge of the resulting when opening or closing the NH fuse gases.
  • the means selectively deliver the gases from the conductor regions of the contact arrangement. This is achieved by the gases are at least partially removed via an arranged directly on the side facing away from the NH fuse side of the contact tulip upper discharge opening and a related discharge channel from a housing formed by the contact protection upwards.
  • Such a preferred embodiment can be realized by at least one discharge channel to the inside (ie in the direction of the housing interior) is integrally formed at an opening in the contact protection substantially directly on the side facing away from the NH fuse side of the extinguishing plates, which with the housing interior in the direction of Contact tulip is connected via an upper discharge opening.
  • This discharge channel preferably has two side walls (in particular substantially perpendicular to the front cover of the housing) and a horizontal bottom, and further preferably has on the side facing away from the NH fuse on a curved bottom upwards. This curvature serves to deliberately not only remove the gases which normally explode explosively during the opening upwards, but also to control the gases and remove them from the entire contact arrangement as efficiently as possible by additionally guiding them forwards.
  • At least one longitudinal web is particularly preferably arranged between the extinguishing plates, which extends at least to the horizontal bottom of the discharge channel, ie which first extends in the gap between the two extinguishing plates and then in the upper discharge opening (the gap between the two extinguishing plates and the discharge opening are not separated from each other, but form a large opening).
  • a vertical inner partition is arranged substantially perpendicular to the plane of the contact tulip, and by this vertical inner partition a Recess has, whose upper part forms the upper discharge opening, and whose lower part forms a lower discharge opening, wherein preferably the at least one longitudinal web also extends over the lower discharge opening, and particularly preferably additional lateral longitudinal webs substantially parallel to at least one longitudinal web in the The additional webs serve in particular for protection against contact.
  • the NH fuse switch disconnector comprises a contact tulip 2, which two spring against each other Contact arms 2.1 and 2.2 has.
  • 3 is one of the best in the FIGS. 3 and 4 identifiable NH fuse denotes, which has on both sides of a fuse body a safety knife, of which in the figures only 4 is shown in each case. In the Figures 1 - 4 this safety knife 4 is received by the contact tuple 2 between the arms 2.1 and 2.2.
  • a contact protection which covers the area of the contact tulip 2 against the user (in each case upward). It is made in one piece and injection molded from a plastic insulating material such as polyamide. Directly above the contact tulip 2, a lead-through opening 6 is released in the contact protection 5, through which the safety blade 4 for turning on and off of the NH fuse switch-disconnector is feasible.
  • the NH fuse 4 is usually attached to a switch cover, not shown here, which is often also applied pivotally. In this case, the NH fuse can be pivoted together with the switch cover around its pivot axis, as indicated by the arrows in the FIGS. 3 and 4 is indicated.
  • the extinguishing plates 7 are integrally formed on both sides and along the pivotal opening 6 on the contact protection as an upstanding narrow ribs. At her in the FIGS. 5 and 6 rear upper corner they are connected to each other via a crosspiece 7.1. Between this crossbar 7.1 and the contact protection 5 also extends a longitudinal web 7.2.
  • the extinguishing plates 7 are generally sufficient as extinguishing means for the arc.
  • switching capacity such as AC 23 at 690
  • the quenching chamber 8 in addition to the above-mentioned quenching chamber 8 to mount on the extinguishing plates 7. The assembly takes place by simply plugging.
  • the quenching chamber 8 comprises a Isolierstoffgeophuse 9 in which a plurality (eg five to ten) about U-shaped quenching plates 10 are inserted and held stacked therein.
  • a plurality eg five to ten
  • guides 11 are provided for the quenching plates.
  • the quenching chamber housing 9 is provided with snap hook 12, which engage in snap openings 13 in the contact protection 5.
  • the two quenching plates 7 engage between the u-shaped quenching plates 10 in the quenching chamber 8 and cover their u-legs aside.
  • the connecting web 7.2 is provided to advantage with correspondingly suitable predetermined breaking points.
  • a region of the contact protection 5, which comes to lie below the rear connection region of the quenching plates when the quenching chamber 8 is plugged forms a breakout opening 14 and breaks out before the extinguishing chamber 8 is plugged on.
  • FIG. 1 and 2 Yet another advantageous embodiment of the inventive NH fuse switch-disconnector is shown, which consists of two guide ribs 15 which are integrally formed on both sides of the lead-through opening 6 for the safety knife 4 and the extinguishing plates 7 approximately opposite to the underside of the contact protection.
  • the guide ribs 15 are further formed so that they engage a distance between the two legs 2.1 and 2.2 of the contact tulip 2 and thereby form a centering and insertion aid for the insertion of the safety blade 4 in the contact tulip 2 when switching.
  • the safety knife 4 comes on contact virtually simultaneously with both Mixulpenschenkeln 2.1 and 2.2 in contact, whereby the unwanted contact bounce and contact erosion are substantially reduced.
  • the two guide ribs 15 are, like the Löchplatten 7, spritzed directly to the contact protection 5 and form insofar as the extinguishing plates an integral part of this.
  • FIGS. 7 to 10 Another embodiment of the present invention is in the FIGS. 7 to 10 shown.
  • the FIGS. 7a ) and 8a) show perspective views of the embodiment without patch extinguishing chamber 8
  • the FIGS. 7b ) and 8b) show corresponding perspective views of the embodiment with attached extinguishing chamber 8.
  • the opening on which the extinguishing chamber 8 is placed if necessary not provided with a Ausbrechplatte, but always open, ie even when used without extinguishing chamber. 8
  • Fig. 7a It can be seen how in the surface of the housing, ie in the contact protection 5 a hole immediately adjacent to the area of the extinguishing plates 7 is present, in which hole a discharge channel 16 is arranged.
  • the longitudinal web 7.2 between the two extinguishing plates is extended downward in this case, so that the upper discharge opening 26 is divided centrally by this longitudinal web 7.2.
  • the discharge channel 16 has a horizontal bottom 17, which is arranged parallel to the upper housing surface and slightly offset in the depth.
  • the recess has a depth of in the range of 8 to 15 mm, which depth of course also depends on the specification of the contact arrangement and the associated size of the NH fuse.
  • the depth is 9mm, for size 2 (400A) and size 3 (630A) 12mm.
  • the discharge channel 16 is bounded by two side walls 18. Also recognizable in Fig. 7a ) are the additional ventilation slots 21 on the front of the housing, as well as additional ventilation slots 22 in the upper side wall of the housing. With upper side wall in this case, the viewer facing side wall of the housing is called. The function of these additional ventilation slots will be seen below.
  • Fig. 8a shows in addition the special configuration of the discharge channel 16. This has in fact in its fuse-remote area on a curved bottom 20.
  • the upward curvature of this lower bottom causes the usually resulting from the contact, explosive wave of hot gases is initially transported parallel to the main direction of the safety knife 4, and then targeted by the curvature in the insertion direction of the fuses, ie Front side of the housing is led out. This is necessary to ensure optimal and efficient discharge of the gases.
  • Fig. 7b The housing 9 of the quenching chamber 8 has on its side facing away from the fuse between the quenching plates 10 via ventilation slots 24, which also ensures efficient removal of the resulting gases from the region of the contacts, and optionally can dissipate occurring heat development.
  • the opening of the discharge channel 16 is not completely covered, but leaves an opening in the region remote from the fuse, so that even with mounted extinguishing chamber 8, the resulting gases are not hindered by the patch chamber. Accordingly, it is also apparent why the curved portion 20 of the bottom of the discharge channel 16 is slightly offset from the trailing edge of the extinguishing plates 7.
  • the quenching chamber 8 is located substantially above the flat bottom 17 of the AbGermankanals 16, ie in this area, the exiting gas is initially performed only parallel to the front of the housing, and only behind the the quenching chamber 9, the gases through the curved bottom 20 deflected out of the recess of the discharge channel 16 out.
  • Fig. 8b shows the contact arrangement with attached extinguishing chamber 8 gem.
  • Fig. 7b in a view from the side of the NH fuses.
  • Fig. 9a 1) shows in particular how the guidance of the gases produced at the contact closure within the housing is further optimized by providing a vertical inner dividing wall 25, which defines the area in which the safety knife 4 is arranged, separated from the other housing interior 28 substantially.
  • the partition wall 25 now has in its uppermost, ie the front side of the housing facing area over the already above-mentioned upper discharge opening 26, which opens into the discharge channel 16.
  • a lower discharge opening 27 is arranged in the partition wall 25, through which emerging gases can escape into the housing interior 28. Accordingly, a first portion of the resulting gases passes through the upper discharge opening 26, and a second portion exits into the area 28. From there, the gases are now prevented from flowing back into the region of the contacts by the partition wall 25.
  • the gases are discharged from the housing interior 28 via the ventilation slots 21 and 22 already mentioned above.
  • the combination of a direct discharge via the discharge channel 16 with an indirect discharge via the lower discharge opening 27 first into the housing interior 28 and then through the slots 21 and 22 to the outside, wherein the vertical inner partition 25 prevents the gases from the housing interior 28 back into the field of contacts proves to be particularly efficient.
  • Fig. 9b again shows the arrangement acc. Fig. 9a
  • the quenching chamber 8 is located substantially above the flat portion 17 of the bottom of 16, whereby an optimal chimney effect can be achieved even when mounted extinguishing chamber 8.
  • FIGS. 10a ) and b) also shows perspective views into the interior of a contact arrangement from below.
  • Fig. 10a it can be seen that the longitudinal web 7.2 and the two lateral longitudinal webs 19 extend not only on the upper discharge opening 26, but also on the lower discharge opening 27. Again, so an increased stability of the construction can be ensured. In particular, but dadruch a further protection against contact is guaranteed.
