Prioritet begard frau den 6 oktober 1962 (Porbundsrepublilcen Tgskland) Foreliggande uppfinning avser en elektrisk effektstrombrytare med flera bredvid varandra anordnade, kopplingsstallena upptagande polpelare for placering i djupled i kopplingsceller av smal konstruktion. Priority claimed from 6 October 1962 (Porbundsrepublilcen Tgskland). The present invention relates to an electric circuit breaker with several connecting pillars arranged next to each other, receiving pole posts for placement in depth in connection cells of narrow construction.

Sam bekant fordras, att kapslade stallverk utforas i smal konstruktion. For att kopplingscellerna for upptagande av kopplingsapparaterna skola kunna hallas sma, ar det nadvandigt att minska de strambrytare, som skola inbyggas eller inkoras i kopplingscellerna, med avseende p& deras lareddimensioner. Flera forslag i denna riktning am a redan kanda. As is well known, nested stables are required to be constructed in a narrow construction. In order to be able to keep the switching cells for receiving the switching devices small, it is necessary to reduce the circuit breakers which are to be built into or plugged into the switching cells, with respect to their wire dimensions. Several proposals in this direction are already known.

Salunda bestar exempelvis en utforingsform i att i holjen placera effektstrombrytare och spanningsfranskilj are med det tot ala tillbeWiret, sasom mattransformatorer, matinstrument och dylikt. For att man skall reda sig med litet utrymme, aro apparaterna sammanforda till grupper, vilka aro inbyggda i ett gemensamt hilje av isolermaterial. De enskilda isolerblocken aro da insatta i cellerna. Harigenom har visserligen en viss. minskning av kopplingscellernas bredd uppnatts, men .denna upphyggnadsprincip som sadan är i tekniskt avseende mycket komplicerad. Salunda consists, for example, of an embodiment in placing circuit breakers and voltage disconnectors in the housing with the total accessory, such as food transformers, food instruments and the like. In order to make room for a small space, the devices must be brought together into groups, which are built into a common housing of insulating material. The individual isolation blocks are then inserted into the cells. Harigenom certainly has a certain. reduction of the width of the coupling cells has been achieved, but this principle of scrapping as such is technically very complicated.

Vidare är det kant att i kopplingscellen forflytta en effektbrytare I polpelarnas plan. Harigenom kan en smal konstruktion uppnas, dock kraver det omfangsrika tillbehoret sa mycket utrymme, att den vunna fordelen till star del ater upphaves. Furthermore, it is an edge to move a circuit breaker in the connection cell in the plane of the pole columns. In this way a narrow construction can be achieved, however, the bulky accessory requires so much space that the advantage gained is largely regained.

Slutligen har man redan foreslagit att forena strombrytarens polpelare till ett gemen samt block av isolermaterial. Harigenorn kan en avsevard minskning av aystanden mellan polpelarna uppnas. Men aven strombrytarens elektriska anslutning kraver ett visst utrymme p6. bredden. Detta mai liar man narmat sig genora forlaggning av isolerade stromledare utefter polpelarnas hada sidor och genom placering av anslutningsstyckena i rat vinkel mot det av polpelarnas axel bestamda planet. Finally, it has already been proposed to unite the circuit breaker's pole pillars into a common and block of insulating material. A significant reduction in the gap between the pole pillars can be achieved. But even the electrical connection of the circuit breaker requires a certain amount of space p6. the width. This may be approached by placing insulated current conductors along the hollow sides of the poles and by placing the connecting pieces at right angles to the plane determined by the axis of the poles.

Genom uppfinningen farbattras en strambrytare av den sistnamnda typen. Enligt uppfinningen aro strOmledarna Iran de strombrytarpoler, som befinna sig bakom den narmast kopplingscellens anslutningsorgan befintliga strombrytarpolen, fram till dessa anslutningsorgan anordnade i gemensamma isolerkroppar, vilka limo anbragta 1 ett sidoplan, som ar parallellt med det genom polrorens axlar lagda planet. Far att kopplingsapparaten bekvamt skall kunna forhindas med anlaggningens elektriska installation, aro de med kopplingscellens anslutningsorgan samverkande anslutningarna for de i isolerkropparna forlagda stromledarna utformade som stickkontakter. De tre stromledarnas stickkontakter are vid en trepolig strombrytare anordnade i triangel. Harigenom har det minsta utrymmesbehovet uppnatts. Isolerkropparna far stramledarna fasthallas i silt lage med hjalp av lister av isolermaterial. Darigenom är en latt uthytbarhet for stromledarna tillforsakrad. Strtimledarna kunna p6. polsidan forbindas med anslutningsbultarna med hj alp av klammor eller medelst stickkontakt- 2 anordningar. I och for toleransutjamning kan forbindningen mellan stromledarna och polpelarnas anslutningsbultar vara utformad Salunda liar den speciella fordelen vunnits, att strOmbrytarens minimala bredddimension erhallits genom den speciella anordningen av strOmledarna. Darutover ar det fardelaktigt, att den stromledarna innehallande isolerkroppen är fast vid polpelarna me-deist en list och ledarna vid hada andarna kunna uppvisa stickkontaktanordningar. Salunda Sr det mojligt att latt anbringa och utbyta strOm.ledarna. The invention provides a circuit breaker of the latter type. According to the invention, the current conductors Iran are the switch poles, which are located behind the switch pole of the nearest switching cell, up to these connecting means arranged in common insulating bodies, which limos are arranged in a side plane parallel to the plane laid by the poles' axes. In order for the coupling device to be conveniently prevented by the electrical installation of the system, the connections cooperating with the connecting means of the coupling cell for the current conductors located in the insulating bodies are designed as sockets. The plugs of the three current conductors are at a three-pole switch arranged in a triangle. As a result, the minimum space requirement has been achieved. The insulating bodies are allowed to hold the tension conductors in a silt layer with the help of strips of insulating material. As a result, an easy extendability for the current conductors is ensured. Strtimledarna can p6. the pole side is connected to the connection bolts by means of clamps or by means of plug connectors 2. For tolerance equalization, the connection between the current conductors and the connection bolts of the pole pillars can be designed. In addition, it is advantageous for the insulating body containing the current conductor to be attached to the pole pillars by means of a strip and the conductors to be able to have plug devices in the case of the spirits. Salunda It is possible to easily apply and replace the current conductors.

Pa bifogade ritning visas ett utfOringsexempel pa uppfinningen. Fig. 1 visar en sidovy ay kopplingscellen med inki5rd effektbrytare. Fig. 2 visar en planvy ay strombrytarens anslutningssida. Fig. 3 visar kopplingscellen sedd uppifran. An accompanying embodiment of the invention is shown in the accompanying drawing. Fig. 1 shows a side view of the switching cell with an integrated circuit breaker. Fig. 2 shows a plan view of the connection side of the circuit breaker. Fig. 3 shows the coupling cell seen from above.

Med 1 betecknas kopplingscellen, som be-star ay strombrytarrummet 2, samlingsskenerummet 3 och anslutningsrummet 4. Strombrytarens polpelare 5 aro uppbyggda pa korsockeln G. Sockeln upptar samtidigt drivmekanismen 7. Stronabrytarens polpelare aro i korriktningen anordnade efter varandra. For att en minimal bredd pa strombrytaren skall uppnas, aro stromledarna 10, vilka fora frau de fasta anslutningsstyckena 8 till strombrytarens p5. avstand liggande polpelare, inbaddada i en gemensam. isolerkropp 9 och p5. en sida forlagda utefter polpelarna. Stromledarna 10 upph5ra p5 anslutningssidan kontaktelement 11, vilka gripa in i anslutningsstyckena 8, exempelvis stickkontakter. Stromledarnas andra ande kan vara fast vid polernas anslutningsbultar medelst en klamanordning 12. Dessa aro tillgangliga fran motsatta sidor 13 och 14 ay isolerkroppen. Dessa utforanden cralla saval for de byre som for de undre str6manslutningarna hos str6mbrytaren. Denoted by 1 is the coupling cell, which consists of the circuit breaker space 2, the busbar space 3 and the connection space 4. The switch poles 5 of the circuit breaker 5 are built on the cross base G. The base simultaneously occupies the drive mechanism 7. The pole columns of the circuit breaker are arranged one after the other. In order to achieve a minimum width of the switch, the current conductors 10, which lead from the fixed connection pieces 8 to the switch p5. spaced pillars, embedded in a common. insulating body 9 and p5. one side placed along the pole pillars. The current conductors 10 terminate on the connection side contact elements 11, which engage in the connection pieces 8, for example plug connectors. The second end of the current conductors can be fixed to the connection bolts of the poles by means of a clamping device 12. These are accessible from opposite sides 13 and 14 of the insulating body. These designs cralla saval for the bearers as for the lower power connections of the switch.

For fasthallning ay isolerkroppen 9 är en list 15 ay isolermaterial anbragt p5. polriirens motsatta sida. Pa isolerkropparna aro fastsattningsutsprang 16 anbragta, vilka gá genom polluckorna och aro mekaniskt forbundna medelst skruvar 17, som ga genona listerna 15. For den upptill belagna stromanslutningen kan listen 18 samtidigt vara forbunden med en kapa 19, som tillsluter polrorens ovre Oppningar. Fig. 2 visar, att stromledarnas anslutningsstycken 11 arc anordnade i triangel och salunda utgora den gynnsammaste anordningen med avseende pa inbesparing av utrymme. For holding the insulating body 9, a strip 15 of insulating material is arranged p5. the opposite side of the polar. Attachment projections 16 are provided on the insulating bodies, which pass through the pole doors and are mechanically connected by means of screws 17, which pass through the strips 15. For the upper current connection, the strip 18 can at the same time be connected to a cap 19, which closes the upper openings of the pole tube. Fig. 2 shows that the connecting pieces 11 arc of the current conductors are arranged in a triangle and thus constitute the most favorable device with regard to saving space.

Av fig. 3 framgar, att str5mbrytarens bredd och salunda kopplingscellens bredd blir mycket liten genom att stromledarna Aro forlagda .endast pa en sida ay polroren. Dessutom framgar, att den elektriska forbindelsen mel lan polroret p5. anslutningssidan och den fasta stickkontaktanordningen 8 kan astadkomInas direkt. Fig. 3 shows that the width of the switch and thus the width of the switching cell becomes very small because the current conductors are located only on one side of the polar tubes. In addition, it appears that the electrical connection between the polar tube p5. the connection side and the fixed plug device 8 can be provided directly.

Det är Oven mojligt att sa naodifiera utforandet, att polrorens ovre anslutning kan bildas av sjalva isolerkropparna. Vidare kan i stallet fOr klamforbindningen mellan polrorens anslutningsbultar och stromledarna aven anvandas en stickkontaktanordning. For att en toleransutjamning mellan strOmledama och bultarna pa polroren skall mojliggOras, kan forbindningen Tara utford bojlig. It is also possible to say that the design of the polar tube can be formed by the insulating bodies themselves. Furthermore, a socket device can also be used in the stable for the clamp connection between the connecting bolts of the polar pipe and the current conductors. In order for a tolerance equalization between the current conductors and the bolts on the polar tubes to be possible, the connection Tara can be challenged.

Slutligen framgar av ritningen, att alla spanningsforande delar aro skyddade mot oavsiktlig beroring och en ljushagsfotpunktsfri konstruktion uppnatts. Finally, the drawing shows that all live parts are protected against unintentional contact and a light-point-free construction has been achieved.
