Description
Die Erfindung· hat eine VorricHtung zur Umwandlung von Wechselstrom, in. Gleichstrom unter Verwendung eines durch einen Dauermagneten polarisierten Relais zum Gegenstand und bezweckt, durch die besondere Anordnung des schwingenden Ankers auf der Kontaktbrücke eine größere Belastung" der Vorrichtung und eine sichere und gleichmäßige Abnahme des Stromes bei hohem Wiräcung-sgrad zu ermöglichen.The invention has a device for Conversion of alternating current, into. Direct current using one through one Permanent magnets polarized relays to the object and the purpose of the particular Arrangement of the oscillating armature on the contact bridge a greater load "the Device and a safe and uniform removal of the current with a high degree of efficiency to enable.
Erfindungsgemäß wird der Anker von einer zwischen zwei Vorsprüngen der an dem· einen Schenkel des Dauermagneten befestigten Kontaktbrücke gespannten Blattfeder getragen, so dtaß er unter Beanspruchung der Elastizität der Feder um seine Mittelachse ausschwingt, während je zwei oder mehrere beiderseits an den Ankerenden angeordnete Kontakte beim Ausschwingen des Ankers gegen- einstellbare Kontaktschrauben der Kontaktbrücke anschlagen. According to the invention, the anchor of one between two projections on the one Leg of the permanent magnet attached contact bridge carried tensioned leaf spring, so dt that it swings out around its central axis when the elasticity of the spring is stressed, while two or more contacts arranged on both sides at the armature ends in When the armature swings out, strike counter-adjustable contact screws on the contact bridge.
Der Erfindungsgegenstand ist auf der Zeichnung in einer Ausführungsform 'dargestellt. Abb. ι zeigt den Gleichrichter in. Stirnansicht, Abb. 2 im Querschnitt und Abb. 3 in Draufsicht ; Abb. 4 ist eine Sonderdarstellung von Ankerbrücke und Anker, während Abb. 5 das Schältungsschema der ganzen Anordnung erkennen läßt.The subject of the invention is shown in the drawing in one embodiment. Fig. Ι shows the rectifier in. Front view, Fig. 2 in cross section and Fig. 3 in plan view ; Fig. 4 is a special representation of the anchor bridge and anchor, while Fig. 5 shows the Circuit diagram of the whole arrangement can be seen.
Der Träger des mechanischen Gleichrichters ist der hufeisenförmige Magnet 1, der mittels der in der Verlängerung der Schenkel vorgesehenen Schraubenbolzen ia, ih unter Zwischenschaltung von Isolierkörpern 2 auf dem in der Zeichnung nicht dargestellten! Deckel des den Transformator und· die Kapazitäten aufnehmenden Kastens befestigt ist. Die Schenkel des Dauermagneten tragen auf ihrer Innenseite j e eine Querlasche 3, 4, die unter sich durch die seitlichen Bolzen 5, 6 zu einem festen Rahmen zusammengefügt sind. Senkrecht zur Lasche 3 stehen zwei Weicheisen- : kerne 7, auf welchen je eine Erregerspule8 aufgeschoben ist. Die andere Lasche 4, welche | die Kontaktbrücke bildet, hat in ihrem mitt- ! leren Teile zwei senkrecht zur Laschenebene stehende, nach innen gerichtete Vorsprünge 4°, 4δ, an deren Stirnenden eine Blatt- : feder 9 befestigt ist, die ihrerseits dien Anker ίο mit den an den Enden paarweise angeordneten Kontakten 11 trägt. Auf der Außenseite der Lasche 4 und gegenüber den Kontakten 11 sind zwei Stege 12 aufgeschraubt, welche an den Enden der stabartigen' Verlängerungen 12a die Leitungsdirähte in Löchern 13 aufnehmen undi zwei zylindrische, mit Muttergewinde versehene Ansätze 14 tragen, die von je einer Stellschraube 15 durchsetzt werden, gegen deren Spitzen sich die Kontäktpaareii beim Ausschwingen des Ankers 10 berührend anlegen.The carrier of the mechanical rectifier is the horseshoe-shaped magnet 1, which by means of the screw bolts i a , i h provided in the extension of the legs with the interposition of insulating bodies 2 on the not shown in the drawing! Lid of the transformer and · the capacitors receiving box is attached. The legs of the permanent magnet each have a transverse tab 3, 4 on their inside, which are joined together by the lateral bolts 5, 6 to form a solid frame. There are two soft iron cores 7 perpendicular to the tab 3, on each of which an excitation coil 8 is pushed. The other tab 4, which | forms the contact bridge, has in its mitt-! Leren parts have two inwardly directed projections 4 °, 4 δ perpendicular to the plate plane, at the ends of which a leaf spring 9 is attached, which in turn carries the armature ίο with the contacts 11 arranged in pairs at the ends. On the outside of the tab 4 and opposite the contacts 11, two webs 12 are screwed, which at the ends of the rod-like 'extensions 1 2 a receive the wire wires in holes 13 and two cylindrical, threaded lugs 14, each supported by a set screw 15 are penetrated, against the tips of which the Kontäktpaareii apply in contact when the armature 10 swings out.
\*om Transformator T geht mittels der beiden Außenleiter a, b der Strom zui den Stegenden 12° der Kontaktbrücke 4, während der Mittelileiter c unmittelbar zum Verbraucher geführt ist. Die Erregerspulen 8 sind1, zum Hauptstromnetz durch die Leitung d~e parallel geschaltet. Der Kondensator K ist vor den Spulen angeordnet, während der Reihenkondensator R parallel zu der vom Gleichrichter kommenden Leitung / und dem Mittelleiter c geschaltet ist. Wie aus dem Schaltungsschema ersichtlich ist, dient der Gleichrichter zur Ausnutzung beider Wechsel.\ * om the transformer T by means of the two outer conductors a, b the current goes to the web ends 12 ° of the contact bridge 4, while the central conductor c is led directly to the consumer. The excitation coils 8 are 1 , connected in parallel to the main power network through the line d ~ e. The capacitor K is arranged in front of the coils, while the series capacitor R is connected in parallel to the line / and the center conductor c coming from the rectifier. As can be seen from the circuit diagram, the rectifier is used to utilize both changes.
Praktische Versuche haben ergeben, daß dieser Gleichrichter selbst bei größeren Frequenzschwankuingen der Wechselstromquelle stets gleichmäßig und ohne Unterbrechung schwingt und stets funkenfrei arbeitet und infolge seiner Unempfindlichkeit, die auf das elastische Schwingen des mit der Blattfeder zusammenwirkenden Ankers zurückzuführen ist, keiner besonderen Wartung bedarf.Practical tests have shown that this rectifier even with larger Frequency fluctuations of the alternating current source always evenly and without interruption vibrates and always works without sparks and due to its insensitivity, which can be traced back to the elastic swinging of the armature interacting with the leaf spring does not require any special maintenance.
