Description
Es ist bereits vorgeschlagen worden, von einer verhältnismäßig kleinen Gleichstrom-Minenzündmaschine, die kurzzeitig von ,Hand oder Federung betätigt wird und die bei direkter Entladung eine vorgegebene Zünderkette nicht zünden kann; einen Kondensator aufzuladen, der, durch geeignete Mittel über die Zünderkette impulsartig entladen, diese zur Entzündung bringt. Dabei kann' auch eine Kondernsatorumschalteinrichtung verwendet werden, die die in Reihe oder parallel aufgeladenen Kondensatoren parallel oder in Reihe für die Entladung über die Zünderkette umzuschalten gestattet.It has already been suggested by a relatively small one DC mine detonator that is operated briefly by hand or by suspension and which cannot ignite a given fuse chain in the event of a direct discharge; a Charging the capacitor, which, by suitable means via the fuse chain in a pulsed manner discharged, causing it to ignite. A capacitor switching device can also be used used, the capacitors charged in series or in parallel in parallel or to switch in series for the discharge via the detonator chain.
Nach der Erfindung wird die Leistungsfähigkeit einer solchen Einrichtung dadurch gesteigert, daß nach Aufladung des Kondensators die Maschine unter Verwendung der Umschaltkontakte entweder in Reihe, was besonders vorteilhaft ist, oder auch mit nicht weiter dargestellten gledchen Polen parallel zum Kondensator geschaltet und dann über die Zünderkette mitentladen wird. Bei der Reihenschaltung kann, was für derart kleine Maschinen sehr günstig ist, diese für eine gegebene Gesamtentladungsspannung für eine nur halb so große Ladespannung dimensioniert werden, was wegen der weit besseren Wicklungsausnutzung infolge der niedrigeren Spannung eine -wesentlich bessere Ausnutzung eines vorgegebenen Modells bewirkt.According to the invention, the performance of such a device increased by using the machine after charging the capacitor the changeover contacts either in series, which is particularly advantageous, or else connected in parallel with the capacitor with small poles not shown and is then also discharged via the fuse chain. When connected in series, what can for such small machines this is very favorable for a given total discharge voltage be dimensioned for only half the charging voltage, which is because of the far Better winding utilization due to the lower voltage - a much better one Exploitation of a given model causes.
In den Fig. i und 2 ist ein Ausführungsbeispiel der Erfindung dargestellt. In Fig. i ist schematisch die Schaltung für den Gegenstand der Erfindung gezeigt. Über die entweder von einem Relais: oder von einem Maschinentrieb nach einem bestimmten Ablaufweg umgeschalteten Kontakte i und 2 wird zunächst der Kondensator 3 aufgeladen und' dann bei der Umschaltung mit der Maschine in Reihe geschaltet und über die Klemmen 5 und 6 auf die angeschlossene Zünderkette entladen.In Figs. I and 2, an embodiment of the invention is shown. In Fig. I the circuit for the subject matter of the invention is shown schematically. Via either a relay: or a machine drive according to a specific one Contacts i and 2 switched over to the drain path, the capacitor 3 is initially charged and 'then connected in series with the machine when switching over and via the Discharge terminals 5 and 6 to the connected fuse chain.
Fig. 2 zeigt den Zusammenbau von Zündmaschine, Kondensator und Umschalteinrichtung. Beispielsweise auf dem vom Handgriff 7 angetriebenen Zahnrad 8 sind zwei isolierte Schleifstücke 9 und io vorgesehen, von denen zuerst die Kontaktstücke i iQ, ii, und IIb, iid und dann ii" iie und iid, iif geschlossen werden. In der ersten Schaltung wird der Kondensator 3" aufgeladen, in der zweiten Schaltung zusammen mit der Maschine in Reihe entladen.Fig. 2 shows the assembly of the blasting machine, capacitor and switching device. For example, on the gear 8 driven by the handle 7, two insulated contact pieces 9 and io are provided, of which first the contact pieces i iQ, ii, and IIb, iid and then ii "iie and iid, iif are closed. In the first circuit, the Capacitor 3 "charged, discharged in series together with the machine in the second circuit.
