Description
455 557 2 Tätning mot luft blir dessutom mindre problematisk, då inga delar av mekanismen behöver frigöras, när det föreligger behov för att byta säkringar. överföringen från utlösararmen till utlösnings- mekanismen kan i en enkel form utgöras av en dragkabel, men i prin- p. cip kan man använda hydraulisk överföring med isolerande vätska eller pneumatisk överföring från säkringshuset till utlösningsmeka- nismen. 455 557 2 Sealing against air also becomes less problematic, as none parts of the mechanism need to be released, when needed to replace fuses. the transfer from the trigger arm to the trigger the mechanism may in a simple form consist of a traction cable, but in principle p. cip you can use hydraulic transmission with insulating fluid or pneumatic transmission from the fuse housing to the release mechanism nismen.
Uppfinningen kännetecknas av de särdrag, som anges i patent- kraven, och kommer nedan att beskrivas under hänvisning till bifo- gade ritning, på vilken fig. 1 visar en konçaktbrytaranläggning sedd från sidan och delvis i sektion, och fig. 2 visar ett snitt genom en del av ett säkringshus med säkring, som är riktad bort från brytaranläggningens framsida.The invention is characterized by the features set forth in requirements, and will be described below with reference to the diagram, in which Fig. 1 shows a contact switch system seen from the side and partly in section, and Fig. 2 shows a section through a part of a fuse housing with fuse, which is directed away from the front of the switchgear.
Huvudkomponenterna, som utgör kompaktbrytaranläggningen i fig. 1, är en lastbrytkammare 1, en utlösningsmekanism 2 och tre säkringshus 3, som innehåller säkringar. Från den bakre delen av varje säkringshus leder ett rör 4 för överföring av rörelsen hos en utlösararm i den bakre delen 5 av varje säkringshus 3. Över- föringen kan exempelvis ske via en dragkabel, som påverkar en manö- verdel 6 för utlösningsmekanismen 2, vilken sörjer för att strömmen brytes, när en säkring går. Den bakre delen 5 är utförd av ledan- de material och har en kontakt 7 för den ena ändkontakten 8 på en säkring 9. Säkringen har en indikeringsanordning 10, och en ut- lösararm 11 anligger mot indikeringsanordningen 10. Utlösararmen 11 står såsom förklaras ovan med hjälp av en dragkabel genom det isolerande röret 4 i förbindelse med utlösningsmekanismen 2 (fig. 1). Om säkringen går, kommer indikeringsanordningen att förskjutas till höger sett såsom i fig. 2, t.ex. av en spänd fjäder, och ut- lösararmen 11 kommer att föras till det läge, som visas med strecka- de linjer. Denna rörelse leder till att vajern 12 i överföringen 4, 12 kommer att draga i utlösningsdelen till utlösningsmekanismen 2, och brytaren utlöses. Man ser av fig. 1, att säkringshusen 3 är lätt åtkomliga från framsidan av kompaktbrytaranläggningen, vil- ken befinfier sig till vänster i fig. 1, när locket 13 avlägsnas w och en säkring kan då lätt bytas ut. Rören 4 av isolerande mate- rial står i bägge de öppna ändarna i förbindelse med den omgivande luften och sträcker sig genom ett rum, som är fyllt med isolerande g gas, t.ex. svavelhexafluorid (SF6), och problemen med tätning avThe main components, which make up the compact circuit breaker system in Fig. 1, is a load breaking chamber 1, a release mechanism 2 and three fuse housing 3, which contains fuses. From the back of each fuse housing leads a tube 4 for transmitting the motion of a release arm in the rear part 5 of each fuse housing 3. the routing can take place, for example, via a traction cable, which affects a part 6 of the tripping mechanism 2, which provides for the current is broken when a fuse blows. The rear part 5 is made of conductive the material and has a contact 7 for one end contact 8 on one fuse 9. The fuse has an indicating device 10, and an output release arm 11 abuts against the indicating device 10. The release arm 11 stands as explained above by means of a pull cable through it insulating tube 4 in connection with the release mechanism 2 (fig. 1). If the fuse blows, the display device will shift to the right as in Fig. 2, e.g. of a tensioned spring, and the release arm 11 will be moved to the position shown by the dashed line. the lines. This movement causes the wire 12 in the transmission 4, 12 will pull the release member to the release mechanism 2, and the switch is triggered. It can be seen from Fig. 1 that the fuse housings 3 are easily accessible from the front of the compact switch system, which is located to the left in Fig. 1, when the cover 13 is removed w and a fuse can then be easily replaced. The insulating material tubes 4 rial is in both the open ends in communication with the surrounding the air and extends through a room, which is filled with insulating g gas, e.g. sulfur hexafluoride (SF6), and the problems of sealing of
