Unteransprüchen.Subclaims.
Die Erfindung wird anhand der folgenden Figuren näher beschrieben: F i g. 1 zeigt eine bekannte Schaltung, F i g. 2 deren Ersatzschaltbild, F i g. 3 eine erfindungsgemäße Schaltung, F i g. 4 deren Ersatzschaltbild, F i g. 5 eine vorteilhafte Ausführung der erfindungsgemäßen Schaltung. The invention is described in more detail with reference to the following figures: F i g. 1 shows a known circuit, FIG. 2 their equivalent circuit diagram, FIG. 3 shows a circuit according to the invention, FIG. 4 their equivalent circuit diagram, FIG. 5 a advantageous embodiment of the circuit according to the invention.
F i g. 1 zeigt den Speicherkondensator 10, der durch von außen gesteuertes Zünden der Schaltfunkenstrecke 20 über die Unterwasserfunkenstrecke 40 entladen wird. F i g. 1 shows the storage capacitor 10, which is controlled by externally Ignition of the switching spark gap 20 is discharged via the underwater spark gap 40 will.
F i g. 2 zeigt das Ersatzschaltbild der in F i g. 1 gezeigten Schaltung. Dabei wird der Generator durch den Speicherkondensator 10, den Generatorwiderstand il und die Generatorinduktivität 12 dargestellt, die Zuleitung durch den Zuleitungswiderstand 31 und die Zuleitungsinduktivität 32, die Unterwasserfunkenstrekke 40 durch den Funkenstreckenwiderstand 41 und die Funkenstreckeninduktivität 42. F i g. 2 shows the equivalent circuit diagram in FIG. 1 circuit shown. In this case, the generator is powered by the storage capacitor 10, the generator resistor il and the generator inductance 12 shown, the lead through the lead resistance 31 and the lead inductance 32, the underwater spark gap 40 through the Spark gap resistance 41 and the spark gap inductance 42.
Die den Stromanstieg begrenzende Induktivität ist die Summe aus der Generatorinduktivität 12, der Zuleitungsinduktivität 32 und der Funkenstreckeninduktivität 42. The inductance limiting the current rise is the sum of the Generator inductance 12, the lead inductance 32 and the spark gap inductance 42.
Fig.3 zeigt eine erfindungsgemäße Schaltung, die sich durch den zur Unterwasserfunkenstrecke 40 parallelgeschalteten Kondensator 50 von der in F i g. 1 gezeigten Schaltung unterscheidet. Aus Fig.3 ist allerdings der erfindungsgemäße integrierte Aufbau des Kondensators 50 in der Zuleitung nicht erkennbar. 3 shows a circuit according to the invention, which is characterized by the for Underwater spark gap 40 parallel-connected capacitor 50 from the in F i g. 1 differs from the circuit shown. From Figure 3, however, is the inventive integrated structure of the capacitor 50 in the supply line cannot be seen.
Dieser wird erst im Ersatzschaltbild, das in Fig.4 gezeigt ist, deutlich. Die Induktivität der Zuleitung 32 wird durch die kleinere Induktivität 52 des Kondensators ersetzt. Der Kondensator 50 wird bei der Zündung der Schaltfunkenstrecke 20 vom Speicherkondensator 10 aufgeladen und bildet mit der Unterwasserfunkenstrecke 40 einen separaten Schwingkreis, in dem die den Stromanstieg begrenzende Induktivität die Summe aus der Kondensatorinduktivität 52 (die kleiner als die Zuleitungsinduktivität 32 ist) und der Funkenstreckeninduktivität 42 ist Selbst wenn die Kondensatorinduktivität 52 nicht kleiner als die Zuleitungsinduktivität 32 ist, wird durch den neuen Schwingkreis erreicht, daß die den ersten Stromanstieg begrenzende Induktivität um die Generatorinduktivität 12 verringert ist.This only becomes clear in the equivalent circuit diagram shown in FIG. The inductance of the lead 32 is determined by the smaller inductance 52 of the capacitor replaced. The capacitor 50 is when the switching spark gap 20 is ignited Storage capacitor 10 is charged and forms with the underwater spark gap 40 a separate resonant circuit in which the inductance limiting the current rise the sum of the capacitor inductance 52 (which is smaller than the lead inductance 32 is) and the spark gap inductance is 42 even if the capacitor inductance 52 is not less than the lead inductance 32, is due to the new resonant circuit achieves that the inductance limiting the first current rise around the generator inductance 12 is reduced.
Gegenüber der bekannten Schaltung (F i g. 1) bedeutet die Anwendung der erfindungsgemäßen Schaltung (Fig.3) eine wesentliche Erhöhung des Stoßwellendrucks und eine steilere Stoßwellenfront, wodurch eine effektive Steinzertrümmerung ermöglicht wird. Compared to the known circuit (FIG. 1) means the application the circuit according to the invention (Figure 3) a substantial increase in shock wave pressure and a steeper shock wave front, which enables effective stone fragmentation will.
F i g. 5 zeigt eine konkrete Ausführung der Erfindung, bei der der Kondensator 50 als Zuleitung zwischen dem Generator 14, der den Speicherkondensator 10 und die Schaltfunkenstrecke 20 enthält, und der Unterwasserfunkenstrecke 40 ausgebildet ist. F i g. 5 shows a specific embodiment of the invention in which the Capacitor 50 as a supply line between the generator 14, the storage capacitor 10 and the switching spark gap 20 contains, and the underwater spark gap 40 is formed is.
Die Induktivität des Leitungssegments, das als The inductance of the line segment known as
Kondensator 50 benutzt wird, beträgt näherungsweise -In (r21r1), seine Kapazität beträgt näherungsweise 2 8 1[ln (r/ri)j-1 wobei gilt: rl = Radius des Innenleiters, r2 = Innenradius des Außenleiters, l = Länge des Kondensators.Capacitor 50 is used, is approximately -In (r21r1), its Capacity is approximately 2 8 1 [ln (r / ri) j-1 where: rl = radius of the inner conductor, r2 = inner radius of the outer conductor, l = length of the capacitor.
Bei der Verwendung von speziellen Dielektrika auf Bariumtitanat-Basis können relative Dielektrizitätskonstanten zwischen 102 und 103 eingestellt werden, was zu Kapazitäten von < 30 nF führt Damit werden Spitzenströme erreicht, die mit den mit der bekannten Anordnung Erreichbaren vergleichbar sind, während die Schnelligkeit des Stromanstiegs verdoppelt wird. When using special dielectrics based on barium titanate Relative dielectric constants can be set between 102 and 103, which leads to capacities of <30 nF are comparable to those achievable with the known arrangement, while the The speed of the increase in electricity is doubled.
