Gasilni pločevinski paket za obločno ugasnilno komoroFire extinguisher package for arc extinguishing chamber
Izum se nanaša na gasilni pločevinski paket za obločno ugasnilno komoro za stikalo, zlasti za zaščitno stikalo voda, sestoječ iz vzporedno ali pahljačasto razporejenih gasilnih pločevin, držalnega dela iz izolacijske snovi s kot črka U zasnovanim prečnim prerezom, v katerega so gasilne pločevine vstavljene položajno fiksirano, in ki v svojem mostiču, ležečem nasproti vstopu obloka, obsega izstopne odprtine za oblok, ki so vsakokrat razporejene med sosednjima gasilnima pločevinama.The invention relates to a fire extinguisher package for an arc extinguishing chamber for a switch, in particular for a water circuit breaker consisting of parallel or fluffy fire extinguishing plates, a holding member made of insulating material having the U-shaped cross-section into which the extinguishing sheets are inserted fixedly , and which, in its bridge opposite the inlet of the arc, comprises the outlet openings for the arc, which are in each case arranged between adjacent fire extinguishers.
Gasilne pločevinske pakete za obločne ugasnilne komore se je bilo predlagalo v najrazličnejših izvedbenih oblikah, njih namen pa je, da se pri preklapljanju, zlasti pri proženju zaščitnih stikal vodov pri odprtju kontaktov nastali oblok hitro spelje proč od kontaktnih delov, pri čemer se oblok, ki se vzpostavi med odpirajočimi kontakti, deloma odpihne z magnetnim poljem stikalnih členov, deloma pa s sesalnim učinkom gasilnega pločevinskega paketa, zatem se vroče pline ohladi med gasilnimi pločevinami in vodi k izstopnim odprtinam obločne ugasilne komore ter skoznje naprej k izpušni odprtini stikala.Fire extinguishing packages for arc extinguishing chambers have been proposed in a variety of embodiments, the purpose of which is to move rapidly away from the contact parts when switching, especially when triggering the circuit breakers when opening the contacts, it is established between the opening contacts, partly blown by the magnetic field of the switch members and partly by the suction effect of the fire extinguisher package, after which the hot gases are cooled between the extinguishing sheets and lead to the exit openings of the arc extinguishing chamber and subsequently to the exhaust opening of the switch.
Naloga gasilnih pločevinskih paketov za obločne ugasilne komore je tudi razdeliti oblok in s tem povečati obločno napetost.The task of fire extinguishing packages for arc extinguishing chambers is also to divide the arc, thereby increasing the arc voltage.
Problem pri znanih gasilnih pločevinskih paketih za obločne ugasilne komore leži tudi v tem, da po izstopu ioniziranih plinov iz izstopnih odprtin za oblok pride do t.im. zunanjih preskokov med sosednjima izstopnima odprtinama za oblok.Takšne zunanje preskoke se da po sebi preprečiti, tako da so izstopne odprtine za oblok majhne. Pomanjkljivost majhnih izstopnih odprtin za oblok pa leži v tem, da ovirajo izstop plina in so s tokovno tehničnega stališča neugodne.A problem with the known extinguishing sheet metal packages for arc extinguishing chambers also lies in the fact that after the exit of ionized gases from the exit openings for the arc, so-called such external jumps can be prevented by themselves so that the arc exit openings are small. The disadvantage of small arc outlets is that they obstruct the gas outlet and are unfavorable from a technical point of view.
Zato se je že predlagalo, da se izstopne odprtine za oblok predvidi v krakih kot črkaTherefore, it has already been suggested that arc outlets should be provided in the arms as a letter
U zasnovanega oblikovanca.U designed designer.
Primer gasilnega pločevinskega paketa za obločno ugasnilno komoro je opisan v AT-B-343 212. Pri tej znani ugasnilni komori obloka so izstopne odprtine za oblok predvidene izključno v krakih kot črka U zasnovanega držalnega dela iz izolacijske snovi, ki drži gasilne pločevine. Pri tej izvedbeni obliki pa sledijo, zlasti pri ozko zasnovanih stikalih, tokovno tehnične težave pri izpihavanju izpuhov iz obločne ugasnilne komore k izpihalnim odprtinam v ohišju stikala.An example of an extinguishing sheet metal package for an arc extinguishing chamber is described in AT-B-343 212. With this known extinguishing chamber, the arc exit openings are provided exclusively in the arms as the letter U of the designed holding member made of insulating material that holds the extinguishing sheets. In this embodiment, however, especially with narrowly designed switches, current-technical problems in blowing the exhaust from the arc-extinguishing chamber to the exhaust openings in the switch housing follow.
Naloga izuma je predlagati gasilni pločevinski paket za obločno ugasilno komoro, ki brez vpliva na učinek in funkcioniranje le-te izboljša izpihavanje izpuhov k izpihalnim odprtinam stikala in prepreči zunanje preskoke.It is an object of the invention to propose an extinguishing sheet metal package for an arc extinguishing chamber which, without affecting the effect and function of the extinguisher, enhances the exhaust flushing of the switch openings and prevents external leaks.
To se po izumu doseže tako, da z zunanje strani mostiča kot črka U zasnovanega držalnega dela štrli navzven vsaj eno rebro, ki medsebojno ločuje sosednji izstopni odprtini za oblok.This is achieved by the invention by projecting at least one rib from the outside of the bridge, such as the letter U of the designed holding member, which separates the adjacent arc exit openings from one another.
Z ukrepi po izumu sledijo v nasprotju z gasilnim pločevinskim paketom za obločno ugasnilno komoro iz AT-B-343 212 izboljšane tokovne razmere, tako da se da obločne pline lažje obvladati in bolje izpihati.The measures of the invention, in contrast to the extinguishing sheet metal package for the arc extinguishing chamber of AT-B-343 212, improve the flow conditions so that the arc gases can be more easily controlled and better expelled.
Z vsaj enim rebrom, ki je po izumu predvideno na zunanji strani mostiča in štrleče od slednjega, sta sosednji izstopni odprtini za oblok medsebojno ločeni na zunanji strani mostiča, tako da je podaljšana pot zraka med izstopnimi odprtinami za oblok sosednjih komor (predvidenih med vsakokratnima dvema sosednjima gasilnima pločevinama). Zunanje preskoke se tako prepreči tudi pri večje dimenzioniranih in zato tokovno ugodnejših izstopnih odprtinah za oblok, čeprav so izstopne odprtine za oblok predvidene v mostiču kot črka U zasnovanega oblikovanca.With at least one rib provided according to the invention on the outside of the bridge and projecting from the latter, the adjacent arc outlet openings are separated from each other on the outside of the bridge so that the air path between the outlet openings for the arc of the adjacent chambers (provided between each two) is extended. adjacent fire extinguishers). External leaks are thus also avoided with larger dimensioned and therefore more streamlined arc outlets, although the arc outlets are provided in the bridge as a U shaped letter.
Pri tem je prednostno, če vsaj eno rebro ne obdaja popolnoma izstopnih odprtin za oblok v mostiču kot črka U zasnovanega oblikovanca. Nasprotno pa se je kot prednostna pokazala izvedbena oblika, pri kateri je predvideno, da rebro obdaja izstopne odprtine za oblok v bistvu le po polovičnih obodih le-teh. Bistveno je le, da se pot zraka med sosednjima izstopnima odprtinama za oblok vzdržuje tako veliko, da se prepreči zunanje preskoke.It is advantageous, if at least one rib does not completely surround the outlet openings for the arc in the bridge as the letter U of the shaped molding. In contrast, an embodiment in which the rib is said to surround the outlet openings for the arc is substantially preferred only in half circumferences thereof. It is only essential that the air path between the adjacent outlet openings for the arch is maintained so large that external leaks are prevented.
Enostavno, vendar učinkovito konstrukcijo gasilnega pločevinskega paketa za obločno ugasnilno komoro po izumu se dobi, če je rebro zasnovano kačasto zavito in vsakokrat obdaja nasproti ležeča območja sosednjih izstopnih odprtin za oblok.A simple but effective construction of an extinguishing sheet metal package for an arc extinguishing chamber according to the invention is obtained if the rib is designed snake-wrapped and surrounds each other opposite the adjacent areas of adjacent arc exit openings.
Izum se razteza tudi na izvedbeno obliko gasilnega pločevinskega paketa za obločno ugasnilno komoro, pri katerem je predvideno, da sta v mostiču kot črka U zasnovanega držalnega dela predvidena dva niza izstopnih odprtin za oblok. Če sta pri tej izvedbeni obliki predvideni dve rebri, je po izumu lahko predvideno, da rebri potekata drugo proti drugemu zrcalno simetrično. S tem se dobi na zunanji strani izstopne odprtine za oblok obsegajočega mostiča držalnega dela vse skupaj troje kanalov (enega med rebri ter po enega med rebrom in sosednjo steno ohišja stikala, v katerega je vstavljen gasilni pločevinski paket za obločno ugasnilno komoro), skozi katere se da odvajati izpuhe brez nevarnosti zunanjih preskokov.The invention also extends to an embodiment of an extinguishing sheet metal package for an arc extinguishing chamber, wherein it is provided that two sets of exit openings for the arc are provided in the bridge as the letter U of the designed holding member. If two ribs are provided in this embodiment, it may be contemplated according to the invention that the ribs are mirror-symmetrical to each other. In this way, a total of three channels (one between the ribs and one between the ribs and one adjacent wall of the switch housing into which the extinguishing sheet metal package for the arc extinguishing chamber) is inserted on the outside of the outlet opening for the enclosing bridge of the holding part, through which to discharge exhaust without the risk of external leaks.
Razpoložljivi prehodni prečni prerez izstopnih odprtin za oblok oz. obločne pline pri izpihavanju iz gasilnega pločevinskega paketa za obločno ugsnilno komoro se da povečati brez nevarnosti za zunanje preskoke, če je po predlogu izuma predvideno, da so izstopne odprtine za oblok zasnovane kot podolgovate luknje, katerih daljša razsežnost poteka vzporedno z gasilnimi pločevinami.Available cross-sectional cross-section of outlet openings for the arc or the discharge gases from the fire extinguisher canopy package for the arc extinguishing chamber can be increased without the risk of external leaks if it is provided in the invention that the outlet openings for the arc are designed as elongate holes, the longer dimension of which extends parallel to the extinguishing sheets.
Pri vseh poprej omenjenih izvedbenih oblikah izuma je vsaj eno rebro prednostno enodelno zasnovano z mostičem kot črka U zasnovanega držalnega dela.In all the aforementioned embodiments of the invention, at least one rib is preferably one-piece designed with a bridge as the letter U of the designed holding member.
Enostavno konstrukcijo gasilnega pločevinskega paketa za obločno ugasnilno komoro po izumu se dobi, če je predvideno, da gasilne pločevine na svojih vzdolžnih robovih nosijo od le-teh proč štrleče in v ravnini gasilnih pločevin ležeče letvaste štrline, ki prijemljejo v ustrezno oblikovane odprtine v krakih kot črka U zasnovanega držalnega dela. Pri tem se ohrani izvedbena oblika, pri kateri je predvideno, da v vse odprtine, predvidene v krakih kot črka U zasnovanega držalnega dela, štrlijo štrline, ki jih nosijo gasilne pločevine.The simple construction of an extinguishing sheet package for an arc extinguishing chamber according to the invention is obtained if it is intended that the extinguishing plates on their longitudinal edges carry projecting moldings projecting on the longitudinal edges of the extinguisher, which engage in properly shaped openings in the arms as letter U of the designed holding part. In this case, an embodiment is maintained in which it is provided that projections carried by the fire extinguishing plates project into all openings provided in the arms as the letter U of the designed holding member.
Nadaljnje prednosti in detajli gasilnega pločevinskega paketa za obločno ugasnilno komoro po izumu sledijo iz nadaljnjega opisa, v katerem je predstavljen izvedbeni primer gasilnega pločevinskega paketa za obločno ugasnilno komoro po izumu, pri čemer kaže sl. 1 prvi izvedbeni primer v pogledu s strani, sl. 2 prerez po črti II-Π s sl. 1, sl. 3 prerez po črti III-ΠΙ s sl. 1 in sl. 4 obločno ugasnilno komoro s sl. 1 v delnem pogledu od zgoraj.Further advantages and details of the extinguishing sheet metal package for the arc extinguishing chamber according to the invention follow from the following description, which illustrates an embodiment of the extinguishing sheet metal package for the arc extinguishing chamber according to the invention, with FIG. 1 is a first embodiment in side view; FIG. 2 is a cross-sectional view taken along line II-Π of FIG. 1, FIG. 3 is a cross-sectional view taken along line III-ΠΙ of FIG. 1 and FIG. 4 is an arc extinguishing chamber of FIG. 1 in partial view from above.
Gasilni pločevinski paket 1 za obločno ugasilno komoro obsega več gasilnih pločevin 2, ki so razporejene medsebojno vzporedno. Vsaka gasilna pločevina 2 obsega na strani vstopa obloka v bistvu kot črka V zasnovan zasek 3.The fire extinguisher package 1 for the arc extinguishing chamber comprises several fire extinguishers 2 arranged in parallel. Each fire extinguisher 2 comprises essentially a letter V-shaped latch 3 on the side of the arc inlet.
Gasilne pločevine 2 so držane z držalnim delom 4 iz izolacijske snovi, kije v prečnem prerezu zasnovan v bistvu kot črka U. Poleg tega obsega vsaka gasilna pločevina 2 na obeh vzdolžnih robovih dve letvasti štrlini 5 in 6, ki sta vstavljeni v ustrezni odprtini 7 in 8 v krakih 9 in 10 držalnega dela 4. Razen odprtin 7 in 8, ki sta zapolnjeni s štrlinama 5 in 6 gasilne pločevine in s tem v bistvu zaprti, ne obsega držalni del 4 v krakih 9 in 10 nikakršnih odprtin.The fire extinguishing plates 2 are held in place by a holding member 4 of insulating material which is substantially cross-sectioned in U. In addition, each extinguishing sheet 2 comprises, on both longitudinal edges, two molded projections 5 and 6, which are inserted in the corresponding opening 7 and 8 in the arms 9 and 10 of the holding portion 4. With the exception of openings 7 and 8, which are filled with projections 5 and 6 of the fire extinguisher, and thus substantially closed, the holding portion 4 in the arms 9 and 10 does not include any openings.
V mostiču 11 držalnega dela 4 so pri prikazanem izvedbenem primeru v dveh nizih 12 in 13 predvidene izstopne odprtine 14 za oblok. Slednje so zasnovane, kot je zlasti prikazano na sl. 4, v obliki podolgovatih lukenj, katerih daljša razsežnost je usmerjen vzporedno z gasilnimi pločevinami 2.In the bridge 11 of the holding part 4, the outlet openings 14 for the arc are provided in the two illustrations 12 and 13 in the illustrated embodiment. The latter are designed as shown in FIG. 4, in the form of elongated holes, the longer dimension of which is oriented parallel to the fire extinguishing sheets 2.
Na zunanji strani mostiča 11 držalnega dela 4 sta predvideni dve rebri 15 in 16, ki, kot je prav tako prikazano na sl. 4, potekata kačasto zavito in vsako od izstopnih odprtin 14 za oblok v bistvu obdajata po njih polovičnem obodu. Na sl. 4 je prikazano tudi, da sta rebri 15 in 16 zrcalno simetrično razporejeni glede na vzdolžno središčno ravnino 17 gasilnega pločevinskega paketa za obločno ugasnilno komoro.Two ribs 15 and 16 are provided on the outside of the bridge 11 of the holding part 4, which, as also shown in FIG. 4, they are serpentine wrapped, and each of the outlet openings 14 for the arch is substantially flanked by a half circumference thereof. In FIG. 4 also shows that the ribs 15 and 16 are arranged symmetrically with respect to the longitudinal center plane 17 of the extinguishing sheet metal package for the arc extinguishing chamber.
Namesto kačasto zavito zasnovanih reber 15 in 16, ki štrlita proč od zunanje strani mostiča 11 držalnega dela 4 in deloma obdajata izstopne odprtine 14 za oblok, so lahko predvidena tudi drugače oblikovana rebra.Alternatively shaped ribs may be provided instead of snake-shaped ribs 15 and 16 projecting away from the outside of the bridge 11 of the retaining portion 4 and partially surrounding the outlet openings 14 for the arch.
Mišljena so npr. rebra, ki so zasnovana obročasto ali delno obročasto. Bistveno je le, da se z rebrom ali rebri poveča pot zraka med medsebojno sosednjima izstopnima odprtinama za oblok.They are meant, for example. ribs that are annular or partially annular. It is only essential that the rib or ribs increase the air flow between the adjacent arc exit openings.
Izum se da povzeti npr. kot sledi:The invention can be summarized e.g. as follows:
Gasilni pločevinski paket 1 za obločno ugasnilno komoro sestoji iz več gasilnih pločevin 2, ki so vstavljene v kot črka U zasnovan držalni del 4 iz izolacijske snovi. V mostiču 11 držalnega dela 4, ležečem nasproti vstopu obloka, so predvidene izstopne odprtine 14 za oblok. Mostič 11 nosi na svoji zunanji strani dve kačasto zaviti rebriThe fire extinguisher package 1 for the arc extinguishing chamber consists of several fire extinguishing plates 2 which are inserted into the U-shaped holding part 4 of insulating material. The outlet openings 14 for the arc are provided in the bridge 11 of the holding portion 4, opposite the arc inlet. Bridge 11 carries two snake-like ribs on its outer side
15, 16, ki povečata pot zraka med sosednjima izstopnima odprtinama 14 za oblok.15, 16, which increase the air path between adjacent outlet openings 14 for the arc.
Tako se prepreči zunanje preskoke, čeprav so lahko izstopne odprtine 14 za oblok tako velike, da ni ovirano iztekanje ioniziranih obločnih plinov iz gasilnega pločevinskega paketa 1 za obločno ugasnilno komoro. Z rebri 15, 16 so skupaj s stenami ohišja, v katerem je nameščen gasilni pločevinski paket 1, v celoti tvorjeni trije kanali za pretok plinov. S tem se nadalje izboljša iztekanje obločnih plinov.This avoids external leaks, although the outlet openings 14 for the arc can be so large that the leakage of ionized arc gases from the extinguishing sheet metal package 1 for the arc extinguishing chamber is not impeded. The fins 15, 16 together with the walls of the housing in which the extinguishing sheet metal package 1 is housed are three gas flow channels. This further improves the leakage of arc gases.
