Description

467 896 10 15 20 25 30 35 av genomslagshållfastheten kan även slutsatser dras av tät- heten i sådana isolergasfyllda ställverk. 467 896 10 15 20 25 30 35 of the impact strength, conclusions can also be drawn from the tightness of such insulating gas-filled switchgear.

För att kunna prova isolergaskvaliteten i sådana ställverk, kan, i ställverkets isolergasutrymme, ett gnist- gap vara anordnat, till vilket högspänningsgeneratorns utgångar ska kopplas.In order to be able to test the insulation gas quality in such switchgear, a spark gap can be arranged in the switchgear's insulation gas space, to which the outputs of the high-voltage generator are to be connected.

Genomslagsspänningsindikatorn består företrädesvis' av en glimlampa, vilken kan 'vara serie- eller parallell- kopplad med gnistgapet. Är den seriekopplad med gnistgapet, lyser glimlampan, när ett överslag äger rum, medan den vid parallellkoppling lyser, så länge inget överslag äger rum och slocknar, när ett överslag sker.The breakdown voltage indicator preferably consists of a glow lamp, which can be connected in series or in parallel with the spark gap. If it is connected in series with the spark gap, the glow lamp lights up when an override takes place, while in parallel connection it lights up, as long as no override takes place and goes out, when an override occurs.

Företräde 'vis är en kondensator parallellkopplad med glimlampan och eventuellt är ytterligare en till kondensator parallellkopplad med piezo-elementet, så att den av piezo- elementet åstadkomna högspänningsimpulsen så uppdelas, att ett överslag i tändgnistgapet endast sker, när en förut- bestämd genomslagshållfasthet hos isolergasen underskrids, så att glimlampan lyser en kort tid.Preferably, a capacitor is connected in parallel with the glow lamp and optionally a further capacitor is connected in parallel with the piezo element, so that the high voltage pulse produced by the piezo element is divided so that an overshoot in the spark gap occurs only when a predetermined break-through strength of the insulating gas undershot, so that the glow lamp lights up for a short time.

Uppfinningen ska nu beskrivas med hjälp av två i rit- ningen visade kopplingsexempel.The invention will now be described with the aid of two connection examples shown in the drawing.

Fig. 1 visar en kopplingsanordning med en med gnist- gapet seriekopplad glimlampa Fig. 2 visar en kopplingsanordning med en med gnist- gapet parallellkopplad glimlampa.Fig. 1 shows a coupling device with a glow lamp connected in series with the spark gap. Fig. 2 shows a coupling device with a glow lamp connected in parallel with the spark gap.

Ett piezo-element 1 har en knapp 2, genom dess manöv- rering åstadkomms en högspänningsimpuls på piezo-elementets 1 utgångar. Piezo-elementets 1 utgångar är via kablar för- bundna med en glimlampa 4 och ett med denna seriekopplat gnistgap 3. Så länge inget överslag sker i gnistgapet 3, flyter ingen ström genom glimlampan 4, -så att den inte lyser. Endast vid ett överslag flyter ström, vilket ger sig till känna genom att glimlampan 4 lyser (en kort tid).A piezo element 1 has a button 2, through its operation a high voltage pulse is produced at the outputs of the piezo element 1. The outputs of the piezo element 1 are connected via cables to a glow lamp 4 and a spark gap 3 connected to it in series. As long as no flashover occurs in the spark gap 3, no current flows through the glow lamp 4, so that it does not light up. Only at a flash does current flow, which is indicated by the glow lamp 4 illuminating (for a short time).

Med glimlampan 4 är en kondensator 5 parallellkopplad och med piezo-elementet 1 är ytterligare en kondensator 6 parallellkopplad. Kondensatorernas 5 och 6 kapacitanser är så valda, att en spänningsdelning sker i ett förhållande som æu MWith the glow lamp 4 a capacitor 5 is connected in parallel and with the piezo element 1 another capacitor 6 is connected in parallel. The capacitors of the capacitors 5 and 6 are so selected that a voltage division takes place in a ratio such as æu M

Claims (7)
