Description
For beskyttelse av elektriske ledninger eller appa-rater mot å bli ødelagt av for høy strøm eller kortslutningsstrøm-mer som er oppstått på grunn av defekter, blir det i den elektriske installasjonsteknikk anvendt smeltesikringer med tilhørende ele-menter, såsom sikringssokkel, bunnskrue og skrutapper. Smeltesikringen er tilpasset etter ledningstverrsnittet eller etter det be-regnede forbruk fra apparatene. I husholdninger og i industrielt bruk som kan sammenlignes med dette felt, blir det vesentlig brukt smeltesikringer fra 2 A til 63 A. Elektriske anlegg i dette strøm-område blir i det vesentlige overvåket av ikke-fagfolk. Således skiftes defekte smeltesikringer av ikke-fagfolk. Likeledes blir ofte elektriske strømkretser brutt ved utskruing av intakte smeltesikringer, f.eks. for å foreta mindre reparasjoner. Utskruing av smeltesikringer er under bestemte betingelser ikke ufarlig, særlig hvis dette blir gjentatt ofte. Mellom det strømførende kontaktsted, f.eks. endekontakten for en smeltesikring og dens opplagring mot fotkontakten eller bunnskruen, kan der oppstå lysbuer som forår-saker materialdeformasjoner og forandringer, som i sin tur kan be-virke et spenningsfall som fører til overoppvarming av beskyttelses-organene og dermed virker skadelig inn på hele sikringen av de til-sluttede ledninger. Men denne fare kan elimineres ved at hver sik-ring har en bryter som muliggjør utskifting av en smeltesikring, uten at spenningen står på. Slike kombinasjoner har imidlertid ikke vært almindelig, da de enten er for dyre eller tar for. stor plass. To protect electrical cables or devices from being destroyed by excessive current or short-circuit currents that have arisen due to defects, fuses are used in electrical installation technology with associated elements, such as fuse bases, bottom screws and screw studs. The fuse is adapted to the cable cross-section or to the calculated consumption from the devices. In households and in industrial use that can be compared to this field, fuses from 2 A to 63 A are mainly used. Electrical installations in this current range are mainly supervised by non-professionals. Thus, defective fuses are replaced by non-professionals. Likewise, electrical circuits are often broken when intact fuses are unscrewed, e.g. to make minor repairs. Unscrewing fuses is not harmless under certain conditions, especially if this is repeated often. Between the live contact point, e.g. the end contact of a fuse and its bearing against the foot contact or the bottom screw, arcs can occur which cause material deformations and changes, which in turn can cause a voltage drop which leads to overheating of the protective devices and thus has a harmful effect on the entire fuse of the connected wires. But this danger can be eliminated by each fuse ring having a switch that enables replacement of a fuse, without the voltage being on. However, such combinations have not been common, as they are either too expensive or take too long. big space.
I tillegg til dette er det ingenting iveien for at en smeltesikring kan skrus ut og inn, uten å betjene bryteren. In addition to this, there is nothing to prevent a fuse being screwed in and out without operating the switch.
Denne ulempe har også de kjente én- og trepolede sikringssokler, som for plassbesparelsens skyld sammen med en bryter er bygget sammen til en enhet. This disadvantage also has the known single- and three-pole fuse bases, which, for the sake of saving space, are built together into a unit together with a switch.
Foreliggende oppfinnelse går ut på å forbedre de tidligere kjente bryter/sikringskombinasjoner, slik at de ovenfor nevnte ulemper i tidligere utførelser elimineres under bibehold-else av begrenset dimensjonering for plassens skyld. The present invention aims to improve the previously known switch/fuse combinations, so that the above-mentioned disadvantages in previous designs are eliminated while maintaining limited dimensions for the sake of space.
Dette oppnås ifølge oppfinnelsen ved at betjeningshåndtaket for bryteren i sin innkoblingsstilling, blokerer muligheten for fjerning av lokket eller kappen for smeltesikringen. Denne blokering kan på en hensiktsmessig og enkel måte oppnås ved at betjeningshåndtaket for bryteren i innkoblingsstilling dekker eller i det minste delvis dekker dekslet for smeltesikringen. Ifølge et ytterligere trekk for oppfinnelsen ble det foreslått at betjeningshåndtaket for bryteren er forsynt med en gjennomsynsåpning for å kunne se smeltesikringens varselsinnretning. This is achieved according to the invention by the fact that the operating handle for the switch in its switch-on position blocks the possibility of removing the lid or cover for the fuse. This blocking can be achieved in an appropriate and simple way by the operating handle for the switch in the switch-on position covering or at least partially covering the cover for the fuse. According to a further feature of the invention, it was proposed that the operating handle for the switch is provided with a viewing opening in order to be able to see the fuse's warning device.
Oppfinnelsen skal i det følgende forklares nærmere under henvisning til tegningen, der fig. 1 viser et utførelseseks-empel for oppfinnelsen, sett fra siden, The invention will be explained in more detail below with reference to the drawing, where fig. 1 shows an exemplary embodiment of the invention, seen from the side,
fig. 2 viser samme innretning som fig. 1, sett oven-fra. fig. 2 shows the same device as fig. 1, top view.
Sikringssokkelen som består av hushalvdeler 1 og 2 opptar en smeltesikring 4' som har endekontaktkapper 3, 3', som ved hjelp av et deksel 5, f.eks. en skruekappe, over en metallisk gjenge 6 står i elektrisk forbindelse med den som en skrueklemme utformede utgangsklemme 7. Mellom tilledningsklemmen 8 og fotkontakten 9 The fuse base consisting of housing halves 1 and 2 accommodates a fusible link 4' which has end contact caps 3, 3', which by means of a cover 5, e.g. a screw cap, over a metallic thread 6 is in electrical connection with the output terminal 7 designed as a screw terminal. Between the supply terminal 8 and the foot contact 9
er der anordnet en bryter 10 so*r> er vist sterkt forenklet på tegningen. Bryteren 10 kan betjenss for hånd eller kan være betjent av en eller annen mekanisme, f.eks. en bimetallutløser. is there arranged a switch 10 so*r> is shown greatly simplified in the drawing. The switch 10 can be operated by hand or can be operated by some mechanism, e.g. a bimetallic trigger.
