Description

Uppfinnare: B Ingvaldsen Prioritet begard !ran den 25 september 1959 (Forbandsrepabliken Tyskland) Vid brytare, i vilka ljusbagen slackes med hjalp av en av ljusbagen sjalv framkallad slaekningsmediestrom, brinner ljusbagen i en slackningskammaranordning, med vars hjalp den av ljusbagen alstrade tryckokningen omsattes i en slackningsmediestriim, 80111 leder till slackning av ljusbagen. Inventor: B Ingvaldsen Priority requested on 25 September 1959 (Federal Republic of Germany) slackening media strip, 80111 leads to slackening of the candle bag.

Eftersom slackningsforloppet sker under loppet av en mycket kort tid, maste ljusbagens styrning med hjalp av slackningskammaranordningen och kopplingsstiftets rorelse samverka pa riktigt satt for att astadkomma sillier slackning. Since the slackening process takes place in the course of a very short time, the control of the candle bag with the aid of the slackening chamber device and the movement of the coupling pin must cooperate in the right way in order to achieve sillier slackening.

Foreliggande uppfinning ger anvisning pa en slackningskammaranordning, i vilken gynnsamma farhallanden i slackningskammaren astadkommas genom kopplingsstiftets rkelse. The present invention provides a slack chamber device in which favorable conditions in the slack chamber are provided by the movement of the coupling pin.

Enligt uppfinningen uppnas detta darigenom, att isolationsdelarna under kopplingsstiftets riirelse till slutlaget kompletterar utstriimningsoppningar, i vilka ljusbagarna utsattas for effektiva stromningar av slackningsmedium. For detta andamal bestar slackningskammaren av en fast, halvcirkuldr del och en rorlig del, som har samma eller liknande form och bildar kopplingsstiftet. Med hjalp av de halvcirkulara isolationsdelarna och rarformiga kontakter bildas en genomgaende, oppen kanal genom slaekningskammaren. I den stationdra delen bildas med hjalp av kontakterna Oppna brytningsstallen, vid vilka ljushagarna, som utdragas av den rorliga delen, brinna vidare. According to the invention, this is achieved in that the insulating parts during the movement of the coupling pin to the final layer complement outflow openings, in which the light beetles are exposed to efficient flows of slack medium. For this purpose, the slackening chamber consists of a fixed, semicircular part and a movable part, which have the same or similar shape and form the coupling pin. With the help of the semicircular insulation parts and rare-shaped contacts, a continuous, open channel is formed through the slacking chamber. In the stationary part is formed with the help of the contacts Open the refractory stall, at which the candlesticks, which are pulled out by the movable part, burn on.

Uppfinningen forklaras nu narmare med hjalp av exempel under hanvisning till bifogade ritningar, som visa tva utforingsformer av en brytare enligt uppfinningen dels i slutet och dels i oppet tillstand. The invention is now explained in more detail with the aid of examples with reference to the accompanying drawings, which show two embodiments of a switch according to the invention, partly at the end and partly in the open state.

I anordningen enligt fig. 1 och 2 aro ut stromningsoppningarna anordnade i den fasta delen av slackningskammaren och oppna mot kammarens rorliga sida genom slitsar eller andra Oppningar, som tillslutas med hjalp av den rorliga delen. In the device according to Figs. 1 and 2, the flow openings are arranged in the fixed part of the slackening chamber and open towards the movable side of the chamber through slots or other openings, which are closed with the aid of the movable part.

Man kan 5.ven dela upp utstromningsoppningarna pa den fasta och den rorliga delen med halften pa vardera, sa att delarna i kopplingsstiftets slutlage sta mitt emot varandra och slackningskammaranordningen darmed är kompletterad pa det satt, som visas pa fig. 3 och 4. You can also divide the outflow openings on the fixed and the movable part by half on each, so that the parts in the end layer of the coupling pin are opposite each other and the slackening chamber device is thus supplemented in the manner shown in Figs. 3 and 4.

Enligt fig. 1 och 2 ar slackningskammaranordningen uppdelad i tva delar, namligen en stationar del och en riirlig del. According to Figs. 1 and 2, the slackening chamber device is divided into two parts, namely a stationary part and a horizontal part.

Pa fig. 1 ar brytaren sluten, medan den pa fig. 2 befinner sig i oppet tillstand. In Fig. 1 the switch is closed, while in Fig. 2 it is in the open state.

I den halveirkulara, stationd.ra delen av slackningskammaren innanfOr holjet 1 aro kontakter 2, 3, 4, 5, 6 och 7, som aro forsedda med avbranningskontakter, anordnade liksom utstromningsoppningar 8, 9 och 10. Donna fasta del av slackningskammaranordningen har en oppen, genomgdende kanal, som innefattar rum, sasom 11 och 12, i de halvcirkulara, rorformiga kontakterna liksom de namnda utstromningsappningarna samt andoppningar 13 och 14. In the semicircular, stationary part of the slackening chamber inside the housing 1 there are contacts 2, 3, 4, 5, 6 and 7, which are provided with burn-out contacts, arranged as well as outflow openings 8, 9 and 10. This fixed part of the slackening chamber device has an open , through channel, which comprises spaces, such as 11 and 12, in the semicircular, tubular contacts as well as the said outflow openings and inlet openings 13 and 14.

Utstromningsoppningarna 8, 9 och 10 aro oppna mot den sida, dar slackningskammarens rorliga del befinner sig, genom var sin slits eller flagon annan slags oppning. The outflow openings 8, 9 and 10 are open towards the side, where the movable part of the slackening chamber is located, through each slot or flake another kind of opening.

I slackningskammarens rorliga del 15, som tjanar som kopplingsstift, aro kontakter 16, 17 och 18 av samma tvarsnittsform som kontakterna i den stationara delen anordnade. Kontakterna 16, 17 och 18 hallas pa avstand Iran varandra genom isolationsstycken 19 och 20 och kopplingsstiftet Or avslutat med ett isolationsstycke 21. 2- - I de isolationsstycken, som bilda utstromningsoppningar, anvander man lampligen ett gasavgivande material, vilket underlattar ljusbagens slackning. In the movable part 15 of the slackening chamber, which serves as coupling pins, contacts 16, 17 and 18 are of the same cross-sectional shape as the contacts in the stationary part are arranged. The contacts 16, 17 and 18 are held at a distance from each other by insulating pieces 19 and 20 and the coupling pin Or terminated with an insulating piece 21. 2- - In the insulating pieces which form outflow openings, a gas-emitting material is suitably used, which facilitates the slackening of the light bag.

Isolationsstyckena 19, 20 och 21 aro utformade pa sadant salt, att halrummen i kopplingsstiftet i slutlaget mynnar ut vid utstromningsappningarna i den fasta delen, sA att aven slackningskammarrummet i den rOrliga delen Ar oppet. The insulating pieces 19, 20 and 21 are formed on such a salt that the cavities in the coupling pin in the final layer open out at the outflow openings in the fixed part, so that also the slackening chamber space in the movable part is open.

Vid sluten brytare gar strommen genom kontakterna 2, 16, 3-4, 17, 5 och 6, 18, 7. Slackningskammarens rorliga del Tried sina isolerande formstycken 19, 20 och 21 har i detta lage sina sidooppningar forskjutna i langdriktningen i forhallande till slitsarna vid sidan av utstromningsoppningarna 8, 9 och 10, sa att de ljusbagar, som utdragas, da. brytaren oppnas, tack vare dessa slitsar kom- ma att brinna i den fasta delen av slack- ningskammaren. Kanalen i derma del 5.r op-pen, sa att slackningsmediet, av vilket den innehaller ett forriid, kan cirkulera. Delta 5.r betydelsefullt vid den normala stromgenomgangen genom brytaren, eftersom kontakterna darigenom kylas. Anordningen arbetar pa foljande satt: DA brytaren oppnas, utdragas ljushagar mellan kontakterna 16, 3-17, 5 och 18, 7. When the circuit breaker is closed, the current passes through the contacts 2, 16, 3-4, 17, 5 and 6, 18, 7. The movable part of the slackening chamber Tried its insulating moldings 19, 20 and 21 have in this layer their side openings offset in the longitudinal direction in relation to the slots next to the outflow openings 8, 9 and 10, said that the light beetles, which are extracted, da. the switch is opened, thanks to which these slots come to burn in the fixed part of the slackening chamber. The channel in this part 5. is open, so that the slackening medium, of which it contains a preform, can circulate. Delta 5. is important in the normal current passage through the switch, as the contacts are thereby cooled. The device works in the following way: When the switch is opened, light fences are pulled out between the contacts 16, 3-17, 5 and 18, 7.

Till foljd av kopplingsstiftets 15 riirelse an- bringas samtidigt isolationsdelarna 19, 20 och 21 mitt for sidooppningarna i den fasta delen och instromningsoppningarna till rummen 22, 23 och 24 kontakterna 16, 17 och 18 oppnas, sa att slackningskammaren i kopplingsstif- tets slutlage, som visas pa fig. 2, far sin slutgiltiga utformning med den fasta och den rorliga delen belagna i huvudsak symmetriskt mitt emot varandra. Following the movement of the coupling pin 15, the insulation parts 19, 20 and 21 are simultaneously placed opposite the side openings in the fixed part and the inflow openings to the rooms 22, 23 and 24 open the contacts 16, 17 and 18, so that the slackening chamber in the coupling pin end layer shown in Fig. 2, has its final design with the fixed and the movable part coated substantially symmetrically opposite each other.

De ljusbagar, som utdragas genom kopplingsstiftets rorelse, brinna mellan de stationara kontakterna 2, 3-4, 5 och 6, 7, innan kopplingsstiftet nar sitt slutlage. The light beetles, which are pulled out by the movement of the coupling pin, burn between the stationary contacts 2, 3-4, 5 and 6, 7, before the coupling pin reaches its final position.

Den mittre ljusbagen, dvs. ljusbagen meIIan korrtakterna 4 och 5, tjanar bade for tryckutveckling och slackning, eftersom dess hada fotpunkter ligga i en effektiv slackningsmedie stromning. The middle candle bag, ie. The light bag between the corrugations 4 and 5, serves both for pressure development and slackening, since its hot focal points lie in an efficient slackening medium flow.

Till foljd av den tryckstegring, som den mittre ljusbagen alstrar i slackningskammaren, drives det slackningsmedium, t. ex. luft, av vilket ett forrad finns i rummen 11, 12 och 23, 24, till utstromningsoppningama 8 och 10. De ljusbagar, som brinna mellan. kontakterna 2, 3 och 6, 7 pa dessa stallen, befinna sig i slackningsmediestromningen, som forstarkes genom avgivning av gasformigt slackningsmedium fran isolationsstyckena runt Oppningarna 8 och 10 och som strommar ut genom slackningskammarens andoppningar 13 och 14. As a result of the increase in pressure which the middle light bag generates in the slackening chamber, the slackening medium is driven, e.g. air, of which there is a supply in rooms 11, 12 and 23, 24, to the outflow openings 8 and 10. The light beetles which burn between. the contacts 2, 3 and 6, 7 in these stalls are in the leaching medium flow, which is amplified by the release of gaseous leaching medium from the insulating pieces around the openings 8 and 10 and which flows out through the inlets 13 and 14 of the leaching chamber.

Vidare dr den tryckutvecklande ljusbagen aven utsatt fiir en effektiv stromning av det slackningsmedium, som avges av isolations materialet i slackningskammarens mittre del 9 och strommar ut fran densamma, eftersom denna ljusbages hada fotpunkter befinna sig i stromningen. Furthermore, the pressure-developing light bag is also subjected to an efficient flow of the slack medium which is emitted by the insulating material in the middle part 9 of the slack chamber and flows out from it, since the base points of this light bag are located in the flow.

Dessa slackningsmediestromningar, som aro riktade mot ljusbagarna, leda till en latt och saker slackning av ljusbagen. These leaching media flows, which are directed towards the candle bags, lead to a latte and things leaching of the candle bag.

Genom slackningskammarens uppdelning i tva delar uppnas, att ljusbagar fOr tryckutveckling och slackning utdragas vid kopplingsstiftets rorelse och att slackningskammaren samtidigt bildas i sin kompletta form, att slackningsmediet forsattes i effektiva stromningar, som aro riktade mot ljusbagarna. Som slackningsmedium kan gas i godtycklig form eller vitska anvandas. For styrning av det utstrommande slackningsmediet kunna slackningskammarens utstromningsOppningar vara forsedda med ventiler. By dividing the slacking chamber into two parts, it is achieved that light beetles for pressure development and slackening are pulled out during the movement of the coupling pin and that the slackening chamber is simultaneously formed in its complete form, that the slackening medium is continued in efficient currents directed towards the light beetles. Gas in any form or whitening can be used as the quenching medium. To control the outflowing slackening medium, the outflow openings of the slacking chamber can be provided with valves.

I slackningskammaren enligt fig. 3 och 1 aro de isolerande begransningsvaggarna for utstromningsoppningarna pa samma sat som i utformningen enligt fig. 1 och 2 var och en uppdelade med ena halften pa den fasta och den andra halften pit' den rorliga delen. In the slackening chamber according to Figs. 3 and 1, the insulating boundary walls for the outflow openings are in the same way as in the design according to Figs. 1 and 2, each divided by one half on the fixed and the other half on the movable part.

I den stationara delen aro kontakter 27, 28, 29, 30, 31 och 32 samt utstromningsoppningar 33, 31 och 35 av halvcirkular form anordnade, varvid kontakterna aro rorformiga for att bilda halrum 36 och 37. Kopplingsstiftet 38, som bildar den andra halften av slackaings- kammaranordningen, bestar av kontakter 39, 40 och 41, saint isolationsstycken 12, 43 och 44, som bilda den ena halften av var sin Opp- ning. Kontakterna och isolationsdelarna ha liknande eller samma form som motsvarande delar av slackningskammarens stationara del. In the stationary part contacts 27, 28, 29, 30, 31 and 32 as well as outflow openings 33, 31 and 35 of semicircular shape are arranged, the contacts being tubular to form cavities 36 and 37. The coupling pin 38, which forms the other half of the slacking chamber device, consists of contacts 39, 40 and 41, saint insulating pieces 12, 43 and 44, which form one half of each Opening. The contacts and the insulating parts have a similar or the same shape as the corresponding parts of the stationary part of the slackening chamber.

Sasom framgar av fig. 3 ligga isolationsdelarna 33, 42-34, 43 och 35, 44 vid oppen brytare symmetriskt mitt emot varandra for att bilda kompletta utstromningsoppningar. Vidare ligga kontakterna centralt i utstrom- ningsoppningarna, sit att ljusbagarna brinna i mellanrummen mellan den fasta och den rorliga delen av slackningskammaren. Slackningskammaranordningen kompletteras genom kopplingsstiftets rorelse. As can be seen from Fig. 3, the insulating parts 33, 42-34, 43 and 35, 44 at open switches lie symmetrically opposite each other to form complete outflow openings. Furthermore, the contacts are centrally located in the outflow openings, where the light beetles burn in the spaces between the fixed and the movable part of the slackening chamber. The slackening chamber device is supplemented by the movement of the coupling pin.

Anordningen arbetar pa foljande satt: brytaren appnas, utdragas ljusbagar mellan den fasta delens kontakter 27, 28-29, 30 och 31, 32 och den rorliga delens kontakter 39, 40-41. Genom kopplingsstiftets rorelse kompletteras samtidigt de halva oppningarna 33, 34 och 35 med hjalp av motsvarande isolationsdelar 42, 43 och 41 i den rorliga delen, sa att de utdragna ljusbagama brinna i kompletta, cirkulara oppningar. Med hjalp av den ljushage, som brinner mellan kontakterna 29 och 30, alstras en tryckstegring, med vars hjalp de ljusbagar, som brinna i Oppningarna 33, 42-34, 43 och 35, 44, utsattas for effektiva slackningsmediestrommar, sa att en latt och saker slackning astadkommes. — —3 The device operates in the following way: the switch is opened, light cups are drawn between the contacts 27, 28-29, 30 and 31, 32 of the fixed part and the contacts 39, 40-41 of the movable part. Due to the movement of the coupling pin, the half openings 33, 34 and 35 are simultaneously supplemented by means of corresponding insulating parts 42, 43 and 41 in the movable part, so that the extended light bags burn in complete, circular openings. With the aid of the light field, which burns between the contacts 29 and 30, a pressure increase is generated, with the aid of which the light beams, which burn in the openings 33, 42-34, 43 and 35, 44, are exposed to effective slackening media drums, so that a lattice and things slackening is accomplished. - —3
