Description
15 20 25 50 35 H0 448 583 2 förhöjning av tryckmotståndskraften hos släckkammaren. " En ytterligare fördel jämfört med den kända släckkammaren består vidare däri, att ljusbågsförloppet stabiliseras i ett plan genom anordnandet av bara en rörlig släckplatta. I förbindelse med släckkammaruppbyggnaden enligt uppfinningen uppnås relativt stor omkopplingsförmåga genom ett ytterligare föredraget kännetecken, att omkopplingskontakten är utförd såsom knivformig med liten tjocklek. 15 20 25 50 35 H0 448 583 2 increase the compressive strength of the extinguishing chamber. A further advantage over the known extinguishing chamber further consists in that the arc sequence is stabilized in a plane by arranging only a movable extinguishing plate. small thickness.
Knivformiga omkopplingskontakter är i och för sig kända. Anord- nandet av en dylik omkopplingskontakt medför emellertid i sam- band med den uppfinníngsmässiga släckkammaren att ljusbågen un- der urkopplingsförloppet redan tidigt erfar intensiv beröring med släckplattorna och i motsvarande grad åstadkommer för ljus- bågssläckningen erforderlig gas) eftersom avståndet mellan plattorna på grund av den tunnväggiga, knivformiga omkopplings- kontakten blir mycket mindre än vid det tidigare kända utföran- det med runt efterhandsbrytstift, som har relativt stor diameter.Knife-shaped switch contacts are known per se. The arrangement of such a switching contact, however, in connection with the extinguishing chamber according to the invention means that the arc during the disconnection process already early experiences intensive contact with the extinguishing plates and correspondingly produces the required gas for the arc extinguishing) because the distance between the plates The thin-walled, knife-shaped switching contact becomes much smaller than in the previously known embodiment with round post-break switch pin, which has a relatively large diameter.
Genom bortfallet av en fjäderbelastad platta uppkommer visser- ligen en minskning av släckplattornas stängningstid, vilket emel- lertid så tillvida ej spelar stor roll, eftersom man genom att anordna en knivformig kopplingskontakt får kraftig minskning av stängningsvägen.Due to the loss of a spring-loaded plate, there is admittedly a reduction in the closing time of the extinguishing plates, which, however, does not play a major role in this respect, since by arranging a knife-shaped coupling contact the closing path is greatly reduced.
De i krav 3 angivna kännetecknen medför kraftig minskning av tröghetsmotståndet och därmed högre urkopplingsacceleration för kopplingskontakten.The characteristics stated in claim 3 lead to a sharp reduction of the inertia resistance and thus higher disengagement acceleration for the coupling contact.
Detta är särskilt fördelaktigt då kopplingskontakten utövar funk- tionen av en efterhandsbrytkontakt, som är parallellkopplad med en frânskiljarkniv med erforderlig strömledningsförmâga och bara är avsedd för lastomkoppling.This is particularly advantageous when the coupling contact performs the function of an after-breaking switch, which is connected in parallel with a separator knife with the required current conductivity and is only intended for load switching.
Uppfinningen beskrives närmare genom ett utföringsexempel med ritning. Fig. 1 visar ljusbågsläckkammaren i tvärsnitt. Fig. 2 visar ljusbågsläckkammaren i fig. 1 i inkopplingstillstånd.The invention is described in more detail by means of an exemplary embodiment with a drawing. Fig. 1 shows the arc extinguishing chamber in cross section. Fig. 2 shows the arc extinguishing chamber of Fig. 1 in the engaged state.
Som framgår av fig; 1 och 2 har släckkammaren ett hölje 1 med en m JI 10 15 448 585 främre öppning 2, genom vilken den här knivformigt gjorda omkopp- lingskontakten 3 når fram till upptagningskontakten N.As shown in FIG. 1 and 2, the extinguishing chamber has a housing 1 with a front opening 2 with a m JI 10 15 448 585, through which this switch-shaped switching contact 3 made reaches the receiving contact N.
Väggpartiet 1' i släckkammarhöljet är förskjutet mot det inre av kammaren på så sätt, att dess ínneryta fungerar som mottrycksyta för släckplattan 7, som är förskjutningsbart lagrad i styrningar.The wall portion 1 'in the extinguishing chamber housing is displaced towards the interior of the chamber in such a way that its inner surface functions as a counter-pressure surface for the extinguishing plate 7, which is displaceably mounted in guides.
Mellan släckplattan 7 och släckkammarhöljet 1 finnes fjädrar 6, som söker förflytta släckplattan i riktning mot mottrycksytan.Between the extinguishing plate 7 and the extinguishing chamber housing 1 there are springs 6, which seek to move the extinguishing plate in the direction of the back pressure surface.
Expansionskammaren är betecknad med referenssiffran 9. Denna kammare är skild från tryckrummet 12 genom begränsningssteget 10 och höljeväggspartiet 1.The expansion chamber is denoted by the reference numeral 9. This chamber is separated from the pressure chamber 12 by the limiting step 10 and the housing wall portion 1.
I fig. 1 befinner sig kopplingskontakten 3 utanför släckkammaren under det att den i fig. 2 visas i inkopplingsläge (3').In Fig. 1, the switching contact 3 is located outside the extinguishing chamber while it is shown in Fig. 2 in switching position (3 ').
Släckkammarhöljet 1 (1') och släckplattan 7 tillverkas av en plast, som på i och för sig känt sätt under inverkan av en ljus- båge avspaltar en gas, verkande som ljusbâgssläckmedel.The extinguishing chamber housing 1 (1 ') and the extinguishing plate 7 are made of a plastic which, in a manner known per se under the influence of an arc, splits off a gas, acting as an arc extinguishing agent.
