Description
Es gibt Gleichstromgeräte-, wie Lragbare Verstä,rker, iM-ieß#ins.tTu-mente, gepolte Elektrolytkondensatoren, die z. B. bei f alscher Polarität nicht arbeiten können oder die euch bei kurzzeitigern# fälschem Anschluß sogar zerstört werden können,. Es ist bekannt, der-artige Geräte über !:;leichrichter, insbesondere Trockengleichrichter, in Einweg- oder Graetzschaltung anzuschließen. Die Einwegschaltung verhindert bei falscher Polarität idas Arbeiten der Geräte, und es muß die Polarität von Hand vertauscht werden. Die Graetzschaltung gestattet zwar die Benutzung ohne Berücksichtigung,der Polarität. Beide Schaltungen haben aber den Nachteil, &ß die Gleichrichter für die volle. Betriebsleistung bemessen sein müssen. Außerdem ist die Spannung durch die- Vorstroraverluste gemindert und sehr stark belastungsabhängig. Es ist weiterhin bekannt, bei Universalgeräten fürGleich- und Wechselstrombetrieb Relais anzuordnen, die,die bei #diesen unterschiedlichen Stromarten notwendigen Schaltungsmaßnahmen vornehmen, indem z. B. ein Relais vorhanden ist"das nur auf Wechselstrom anspricht. Es ist atich bekannt, das Anlegen an diie richtige Polaritä:t durch ein Relais mit vorgeschaltetem Einweggleichrichter zu bewirken. jedoch kann bei diesem Vorschlag kurzzeitig die falsche Polarität wirksam werden.There are direct current devices, such as portable amplifiers, iM-iess # ins.tu-ments, polarized electrolytic capacitors, which z. B. at f Alscher polarity can not work or you can even be destroyed in kurzzeitigern # fälschem connection ,. It is known to connect such devices via!:; Light rectifiers, in particular dry rectifiers, in a one-way or Graetz circuit. The one-way circuit prevents the devices from working if the polarity is incorrect, and the polarity must be reversed by hand. The Graetz circuit allows use without considering the polarity. Both circuits have the disadvantage, however , that the rectifier for the full. Operating performance must be measured. In addition, the voltage is reduced by the pre-flow losses and is very much dependent on the load. It is also known to arrange relays in universal devices for direct and alternating current operation which carry out the switching measures necessary for these different types of current, e.g. B. a relay is available "which only responds to alternating current. It is atich known to effect the connection to the correct polarity by a relay with an upstream half-wave rectifier. However, with this proposal the wrong polarity can be effective for a short time.
Die Effinidung vermeidet die genannten Fehler durch Anordnung eines oder zweier polarisierter Relais., die nur bei Erregung mittels ihrer Kontakte den Verbraucher stets mit richtiger Polarität an die Stromquelle leg-en. Man kann nach der Erfindung auch zwei normale Relais, die je idurch Gleich-.richter, vorzugsweise durch. Einwegtrockengleichrichter entgegengesetzt polarisiert sind, #durch Zusammen-arbeiten ihrer Kontakte veranlassen, die Verbraucher stets nur m-it richtiger Polarität einzuschalten. An ihre Stelle können auch zwei entgegengesetzt permanent magnetisch oder elektro-.statisch polarisierte Relais treten, die #so justiert sind, daß ihre Anker im unerregten Zustande abf allen.The optimization avoids the errors mentioned by arranging one or two polarized relays, which only connect the consumer with the correct polarity to the power source when they are excited by means of their contacts. According to the invention, it is also possible to use two normal relays, each through rectifier, preferably through. Disposable dry rectifiers are polarized in opposite directions # by working together their contacts cause the loads to be switched on only with the correct polarity. They can also be replaced by two oppositely magnetically or electro-statically polarized relays, which are adjusted so that their armatures drop off when they are not excited.
In den Fig. i bis 3 ist der Gegenstand der Erfindung an mehreren Ausführungsbeispielen dargestellt. In. der Fig. i ist an die Klemmen i und 2, die Gleichstromquelle mit beliebiger Polarität angeschlossen. Das Gleichstromgerät 3, #dessen Polarität auch nicht kurzzeitig verwechselt werden soll, ist an die Klemmen 4 und 5 angeschlossen. Parallel zu den Klemmen i und :2 liegt die Erregerwicklung eines permanent, z. B. mit einem Dauermagneten polarisierten Relais 6 mit Mittelstellung der beweglichen Kontakte in unerregtem Zustande der Wechselkontakte 6 w i und 6 w 2. Beim Anlegen an die -Gleichstromquelle schließen dieWechselkontakte den Gleichstromverbraucher 3 mit richtiger Polarität an. In der Fig. 2 sind zwei Relais 6 p und 6 m ohne 11itteleinstellung v"orgeseh#ii#., --die - ebenfallg entweder permanent polarisiert und die dann auf Ab- fallen -bei Fehlen der Erregung justiert sind oder die, vorzugsweise aJs gewöhnliche neutrale Relnis ausgeführt, durch, die vorgeschalteten, gestrichelt -angedeuteten Einweggleichrichter 7el und 7e?-polarisiert werden. Die Relais besitzen je zwei Arbeits,kontakte6pa-i und 6pa2bzw.zweiWechselkontakte 6 mw i und 6 mw 2, die den Verbraucher 3 stets nur an #die richtige Polarität legen. - Nach der Fig. 3 kann mandie Relais, 6 p und 6 M mit je einer weiteren Wicklung 6 p ibzw. 6 m i versehen, die unter sich in Reihe geschaltetbei ihrer Erregung eine Fezneinschaltung des Verbrauchers mit richtiger Polarität gestatten.In Figs. I to 3 , the subject matter of the invention is shown in several embodiments. In. i is connected to terminals i and 2, the direct current source of any polarity. The DC device 3, # whose polarity should not be confused for a short time, is connected to terminals 4 and 5 . The field winding of a permanent, z. B. with a permanent magnet polarized relay 6 with central position of the movable contacts in the unexcited state of the changeover contacts 6 wi and 6 w 2. When applied to the DC source, the changeover contacts connect the DC load 3 with the correct polarity. In FIG. 2, two relays 6, p and m 6 without 11itteleinstellung v "orgeseh # # ii, --the -. Ebenfallg either permanently polarized and which then fall on waste -in the absence of the excitation are adjusted, or that, preferably AJS ordinary neutral Relnis executed by the upstream dashed -angedeuteten wave rectifier 7el and 7e? be -polarisiert. the relays have two working, kontakte6pa-i and i 6pa2bzw.zweiWechselkontakte 6 mw and 6 mw 2, the consumer always only 3 put the correct polarity at #. - According to Fig. 3 , the relays 6 p and 6 M can each be provided with a further winding 6 p and 6 mi, which are connected in series when they are excited to switch on the consumer with the correct polarity allow.
