Description

Sperreanordning for skillebrytere. Locking device for disconnectors.

Det cr kjent i koblingsa.nlegg å benytte skillebrytere so.-:, mandvreres f oi' hånd ved hjelp av en suikknokkel via en dreibar criv-aksel. For å gjore dette stikker uran ndkkelen Inn i en åpning ved enden av urivakseien og dreier denne til den respektive jnctsatte endestilling. For låsning av drivakselen mot utilsiktet dreining ved uttrukket nokkel er det kjent å utfore innstikningsåpningen gjennom-gående og la en bevegelig lagret stift so;., er anordnet loddrett på drivakselens akse og står under fjcorkraft, smekke inn i innstikningsåpningen når ndkkelen trekkes av. Til grunn for den forliggende opp-finnelse ligger nå den oppgave å utvikle en slik sperreanordning for skillebrytere videre slik at den uten vesentlige r.eromkostninger også forhindrer omkobling når koblingsndkkelen ikke er stukket helt inn, og at det ved hjelp av en ekstra sperreanordning uten rnerou.kost-ninger forhindres at koblingsnokkelen blir stukket inn eller trukket av nar drivakselen befinner seg i en mellomstilling mellom, sine to fastlagte endestillinger.. ,. It is known in switchgear to use disconnectors so.-:, operated by hand with the help of a sui knuckle via a rotatable criv shaft. To do this, the uranium key is inserted into an opening at the end of the watch axis and turns this to the respective jncted end position. To lock the drive shaft against accidental rotation when the key is pulled out, it is known to make the insertion opening through and let a movable bearing pin so;., which is arranged vertically on the axis of the drive shaft and is under force, snap into the insertion opening when the key is pulled off. The present invention is now based on the task of further developing such a blocking device for disconnectors so that it also prevents switching without significant operating costs when the switching key is not fully inserted, and that by means of an additional blocking device without rnerou .costs are prevented from the coupling key being inserted or pulled off when the drive shaft is in an intermediate position between its two fixed end positions.. ,.

Således angår oppfinnelsen en sperreanordning for skillebrytere som mandvreres for hånd via en dreibart lagret drivaks^l forsynt med innstikningsåpning for en koblingsndkkel, og hvor 'der ;r anordnet en forrigling som bare i endestillingene tillater'innstikning og uttagning av koblingsnokkelen, saint 'hvor der ved uttrukkét koblingsndkkel rager en fjærbelastet stift inn i innstikningsåpningen på Thus, the invention relates to a locking device for disconnectors which is operated by hand via a rotatably mounted drive shaft provided with an insertion opening for a coupling key, and where a locking device is provided which only allows insertion and removal of the coupling key in the end positions, where when the coupling key is pulled out, a spring-loaded pin protrudes into the insertion opening on

tvers av drivakselens akse. Det nye består i at der i en tverrboring i drivakselen mellom omkretsen og innstikningsåpningen er bevegelig ]ågret..en kule, som ved .delvis innstukket.koblingsndkkel rager utenfor omkretsen av drivakselen og ligger an mot kanten av et anslagsstykke som delvis omgir drivakselen, og at der på et sted av koblingsnokkelen finnes en forsenkning som ..kulen ved .fullt innstukket .koblingsndkkel kan vike ut i . across the axis of the drive shaft. The new feature consists in the fact that in a transverse bore in the drive shaft between the circumference and the insertion opening there is a movable ball, which, when the coupling is partially inserted, protrudes outside the circumference of the drive shaft and rests against the edge of a stop piece that partially surrounds the drive shaft, and that somewhere on the coupling key there is a depression into which the ball can deflect when the coupling key is fully inserted.

lit utfdrelseseksempel på skillebryteren er vist i snitt A small example of the circuit breaker is shown in section

på fig. 1 og 2 for to forskjellige vinkelstillinger av drivakselen. Fig. 3 og h viser det samme som fig. henholdsvis 1 og 2, sett ovenfra og delvis i snitt. Fig. 5 er et sideriss av anordningen, likeledes delvis i snitt. on fig. 1 and 2 for two different angular positions of the drive shaft. Fig. 3 and h show the same as fig. 1 and 2 respectively, seen from above and partially in section. Fig. 5 is a side view of the device, also partly in section.

Drivakselen 1 har en innstikningsåpning 2 hvori der er stukket inn en koblingsndkkel 3 r"ed motsvarende tverrsnitt. Midtpartiet 4 av et U-formet aksellager 5 tjener som anslagsstykke. I en tverrboring 6, som forbinder innstikningsåpningen 2 med omkretsen av drivakselen 1, sitter en bevegelig lagret kule 7. I en ytterligere tverrboring er der anbragt en anslagsskrue 8 til å begrense dreie-vinkelen for'drivakselen 1. Koblingsnokkelen har på et sted av sin aksiale lengde forsenkninger 9 som ved fullt innstukket koblings-ndkkel ligger i hdyde med anslagsskruen 8 og kulen J. Dessuten er en stift 10, som står under virkningen av en fjær 11, på i og for seg kjent måte lagret slik at den ved uttrukkét stikkndkkel rager inn på tvers i bryter akselens innstikningsåpning 2 (fig. 5)- Derved er det sikret at drivakselen er sperret mot dreining ved uttrukkét koblingsndkkel. Da det i det foreliggende utfdrelseseksempel dreier seg om en drivaksel som må dreies l8o° for at den tilhdrende skillebryter skal nå sin annen endestilling, strekker innstikningsåpningen seg på to l80° forskjdvne steder ut til drivakselens omkrets. Av samme grunn omgir anslagstykket ll halve omkretsen av drivakselen. The drive shaft 1 has an insertion opening 2 into which a coupling key 3 with corresponding cross-section is inserted. The middle part 4 of a U-shaped axle bearing 5 serves as a stop piece. In a transverse bore 6, which connects the insertion opening 2 with the circumference of the drive shaft 1, a movably mounted ball 7. In a further transverse bore, a stop screw 8 is arranged to limit the angle of rotation of the drive shaft 1. The coupling key has depressions 9 at one point along its axial length which, when the coupling key is fully inserted, are level with the stop screw 8 and the ball J. In addition, a pin 10, which is under the action of a spring 11, is stored in a manner known per se so that when the plug is pulled out, it protrudes transversely into the insertion opening 2 of the breaker shaft (fig. 5) - Thereby it ensured that the drive shaft is blocked against rotation when the coupling key is pulled out. As the present example of a drive shaft is concerned with a drive shaft that must be turned l8o° in order for the associated disconnect switch to cal reach its second end position, the insertion opening extends in two 180° staggered locations out to the circumference of the drive shaft. For the same reason, the stop piece ll surrounds half the circumference of the drive shaft.

Virkemåten av den beskrevne anordning er sot;; folger1: The operation of the described device is sot;; follower1:

Når koblingsnokkelen ikke er stukket inn (fig. b)> rager sperre- When the coupling key is not inserted (fig. b)> the locking

stiften 10 inn i innstikningsåpningen 2 i drivakselen 1, så denne ikke lar seg dreie. Fig. 1 og 3 anskueliggjdr forholdene når koblingsnokkelen ikke er stu""ket helt inn. Stiften 11 ei' allerede ved hjelp av den avskråneoe påldpskant av koblingsnokkelen j blitt trykket ut til sin utldsningsstilling. Det sentrale parti av koblingsnokkelen i innstiknirr^ - åpningen 2 trykker kul on 7 utover. Kulen r;-jger utenfor omkretsen av drivakselen 1 og ligger an mot anslaget <l>\, så der heller ikke i denne stilling kan skje noen dreining av drivakselen. Til å sikre drivakselen mot å divies i den motsatte retning tjener anslagsskruen b. Koblingsnokkelen kan altså i denne stilling trekkes ut eller stikkes lenger inn. Fig. 2 og 4 viser situasjonen ved fullt innstukk e; koblingsndkkel etter ubetydelig dreining av drivakselen 1. Da koblingsndkkelen er stukket helt inn, befinner forsenkningene 9 i koblings-nokkelen seg i hdyde med kulen 7. Derved har' denne mulighet for å the pin 10 into the insertion opening 2 in the drive shaft 1, so that it cannot be turned. Fig. 1 and 3 illustrate the conditions when the coupling key is not fully inserted. The pin 11 has already been pressed out to its release position by means of the bevelled bearing edge of the coupling key. The central part of the coupling key in the plug-in opening 2 presses cool on 7 outwards. The ball r;-jgers outside the circumference of the drive shaft 1 and rests against the stop <l>\, so that no turning of the drive shaft can take place in this position either. The stop screw b serves to secure the drive shaft against splitting in the opposite direction. The clutch key can therefore be pulled out or pushed in further in this position. Fig. 2 and 4 show the situation with full insertion e; coupling key after a slight rotation of the drive shaft 1. When the coupling key is fully inserted, the recesses 9 in the coupling key are at the height of the ball 7. This has the opportunity to

vike ut innover så den ikke lenger rager utenfor omkretsen av drivakselen 1. I denne stilling er altså en dreining av drivakselen 1 bend inwards so that it no longer protrudes outside the circumference of the drive shaft 1. In this position, therefore, a rotation of the drive shaft 1

uten videre mulig. Kan ser at anslaget 4 ligge- direkte an på drivakselen 1. Dette .gjelder for hele den vei kulen tilbakelegger under dreining av drivakselen 1 fra den ene endestilling til den annen. without further ado. You can see that the stop 4 rests directly on the drive shaft 1. This applies to the entire path the ball travels during rotation of the drive shaft 1 from one end position to the other.

Lerved blir det i enhver koblingsstilling med unntagelse av de to endestillinger forhindret at kulen 7 kan bevege seg utover igjen. By means of this, in any coupling position with the exception of the two end positions, the ball 7 is prevented from moving outwards again.

Den kan altså ikke forlate forsenkningen 9 i koblingsnokkelen, så It cannot therefore leave the recess 9 in the coupling key, so

denne ikke kan trekkes ut i noen mellomstilling. this cannot be withdrawn in any intermediate position.

Dermed utmerker den nye anordning seg ved en særlig enkel oppbygning av forrigelingsanordningen, da den bevegelige kule har en dobbelt funksjon: For det fdrste tjener den til å sperre drivakselen når koblingsnokkelen ikke er stukket helt inn, og for det annet tjener den til å sikre koblingsnokkelen når drivakselen ikke står i noen endestilling. I tillegg til dette blir det oppnådd at drivakselen til enhver tid er synlig forfra, så en mekanisk stillingsviser kan forbindes direkte med drivakselen. Dessuten er det på enkel måte mulig å trekke koblingsndkkelakselen ut forlover fra koblingseellen, Thus, the new device is distinguished by a particularly simple construction of the pre-distribution device, as the movable ball has a double function: firstly, it serves to block the drive shaft when the coupling key is not fully inserted, and secondly, it serves to secure the coupling key when the drive shaft is not in any end position. In addition to this, it is achieved that the drive shaft is always visible from the front, so a mechanical position indicator can be connected directly to the drive shaft. In addition, it is possible to easily pull the coupling end shaft out of the clutch from the coupling shaft,

da der ikke finnes noen tildekkende kappe foran koblingsndkkelakselen. Derved får man på enkleste måte mulighet for å inn- og avmontere koblingsakselen. as there is no covering cover in front of the coupling key shaft. This gives you the opportunity to install and remove the coupling shaft in the simplest way.
