Description
Durch eine Gießharzplatte isoliermitteldicht durchgeführte stromführende Bolzen, insbesondere für Transformatoren, Meßwandler oder dergl. Die Neuerung betrifft durch eine Gießharzplatte isoliermitteldicht durchgeführte stromführende Bolzen, insbesondere für Transformatoren, Meßwandler oder dergl.Live current carrying through a cast resin plate Bolts, especially for transformers, transducers or the like. The innovation relates current-carrying bolts passed through a cast resin plate so that they are insulated, especially for transformers, transducers or the like.
Bei unter Einschrumpfung in die Gießharzplatte durchgeführten stromführenden Bolzen tritt oft der Fall ein, daß die bei Temperaturschwankungen, Kurzschluß oder Dauerströmen entstehenden großen Unterschiede in der Wärmeausdehnung der stromführenden Bolzen und dem einbettendem Gießharz zu einem Reißen der Gießharzplatte und damit zu Undichtigkeiten führen.In the case of current-carrying The bolt often occurs that the temperature fluctuations, short circuit or Continuous currents result in large differences in the thermal expansion of the current-carrying ones bolt and the embedding cast resin to cracking of the cast resin plate and thus to leaks to lead.
Um diesbezüglich Verbesserungen zu erzielen, sind gemäß der Neuerung die Bolzen im Zuge ihrer Durchführung durch die Gießharzplatte teilweise in Gießharz dicht eingebettet und auf der dem Gehäuseinneren zugewandten Seite oder beiderseits der dichten Gießharzeinbettung mit membranartigen, mit ihren Rändern ebenfalls in das Gießharz eingebetteten Scheiben durch Löten, Schweißen oder dergl. dicht verbunden.In order to achieve improvements in this regard, are according to the innovation the bolts in the course of their implementation through the cast resin plate partly in cast resin tightly embedded and on the side facing the inside of the housing or on both sides the dense cast resin embedding with membrane-like, with their edges also in the cast resin-embedded disks are tightly connected by soldering, welding or the like.
In den Figuren 1 bis 3 sind verschiedene Ausführungsbeispiele der neuerungsgemäßen Durchführung für die stromführenden Bolzen 1 durch die Gießharzplatte 2 gezeigt ; die Figur 1a stellt eine andere Ansicht der Figur 1 dar.In Figures 1 to 3 are different embodiments of the innovation according to implementation for the current-carrying bolts 1 through the cast resin plate 2 shown; FIG. 1a shows another view of FIG.
In der Figur 1 ist die dichte Einbettung dadurch erreicht, daß die Bolzen Ausnehmungen 3 aufweisen, in die das Gießharz beim Einbetten eindringt. Dies ergibt von a... b eine feste Verankerung. Im Zuge b... c und d... e befindet sich zwischen den Bolzen 1 und dem Gießharz ein Trennmittel, z. B. Silikonfett, das eine feste Verbindung zwischen. dem Gießharz und den Bolzen verhindert und den Bolzen Längs-und Querausdehnungen gestattet.In the figure 1, the tight embedding is achieved in that the Bolts have recesses 3 into which the casting resin penetrates during embedding. this results in a solid anchorage from a ... b. In the course of b ... c and d ... e is located between the bolt 1 and the casting resin, a release agent, for. B. silicone grease, the one fixed connection between. the cast resin and the bolt prevented and the bolt Longitudinal and transverse expansion permitted.
Durch die Einbettung membranartiger Scheiben 4 in Gießharz und durch ihre Verlötung mit den Bolzen 1 wird die Dichtung gegenüber dem von unten wirkenden Isoliermittel im Gehäuse erreicht.By embedding membrane-like disks 4 in cast resin and by their soldering with the bolt 1 is the seal against the one acting from below Reached insulation in the housing.
Außerdem wird ein elastischer Ausgleich von Längs-und Querdehnungen
erzielt. Im Zuge c... d sind Ringnuten 5 gebildet, deren drei Durchbrüche 6 (Figur
1a) bis an die untere Plattenflache reichen. Dadurch ergeben sich Kanäle, durch
die das Iso-
Beim Ausführungsbeispiel der Figur 2 sind die membranartigen Scheiben 4 beiderseits der dichten Einbettung (a...b) vorgesehen, während das T'sennmittel nunmehr oberhalb bzw. unterhalb der Verlötungen derselben (... d, e... f) zwischen Bolzen und Gießharz vorhanden sind.In the embodiment of Figure 2, the membrane-like disks 4 provided on both sides of the tight embedding (a ... b), while the separating medium now above or below the soldering of the same (... d, e ... f) between Bolts and resin are present.
Beim Ausführungsbeispiel der Figur 3 sind die Innenränder der Scheiben 4 wellrohrförmig umgebördelt. Die feste Bolzenverankerung im Gießharz erfolgt über die in die Bolzen eingedrehten Querrillen 7 ; auch hier sind Ringnuten 5 und Durchbrüche 6 vorhanden.In the embodiment of Figure 3, the inner edges of the discs 4 flanged in a corrugated tube shape. The fixed bolt anchoring in the cast resin takes place via the transverse grooves 7 screwed into the bolts; here, too, there are annular grooves 5 and openings 6 available.
