Patentiert im Deutschen Reiche vom 4. August 1934 abPatented in the German Empire on August 4, 1934

In. der Patentschrift 580 530 ist eine Schalteinrichtung angegeben,die in Stromeraeugungs» anlagen mit Samrnlerbetrieb benutzt werden und eine einfache Bedienung einer solchen Anlage ermöglichen soll.In. of patent 580 530 is a switching device which are used in power generation systems with collector operation and should enable simple operation of such a system.

Schalteinrichtuingen, die nach diesem Patent gebaut wurden, haben den Nachteil, daß- man den die Dynamomaschine mit der Batterie über die Schaltkontakte eines Rückstrom-Schützes verbindenden Steuerschalter und das Rückstromschütz räumlich nicht trennen kann, weil hier die am Rückstromschütz vorhandene Zugfeder mechanisch durch den Steuerschalter beeinflußt wird.Switching devices that were built according to this patent have the disadvantage that one the dynamo with the battery via the switching contacts of a reverse current contactor the connecting control switch and the reverse current contactor cannot be spatially separated, because here the tension spring on the reverse current contactor is mechanically controlled by the control switch being affected.

Dieses ist nachteilig, weil häufig besonders auf Schiffen kein Platz vorhanden ist, um Schalteinrichtungen dieser- Art unterzubringen. This is disadvantageous because there is often no space, especially on ships, to To accommodate switching devices of this type.

Der Nachteil wird durch vorliegende Erfindung beseitigt, indem nunmehr Steuerschalter und Rückstromschütz räumlich getrennt werden. Der Steuerschalter muß natürlich in erreichbarer Höhe, das Rückstromschütz kann aber an einer ganz anderen Stelle, wo mehr Platz ist, ,angebracht werden. Außerdem bietet die vorliegende Erfindung für die Herstellung Vorteile.The disadvantage is eliminated by the present invention by now control switch and reverse current contactor are spatially separated. The control switch must of course be at an accessible height, the reverse current contactor but can be attached in a completely different place where there is more space. In addition, the present invention offers manufacturing advantages.

Benutzt man die Rückstromschütze, so besteht die Gefahr, daß das Rückstromschutz zu tanzen ,anfängt, sobald es die Auslösestellung erreicht. Dieses Tanzen kann man verhindern, indem man in an sich, bekannter Weise die Spannungsspule des Rückstromschützes in der Betriebsstellung durch Vorschaltung eines Widerstandes schwächt.If the reverse current contactors are used, there is a risk that the reverse current protection begins to dance as soon as it reaches the trigger position. You can dance this prevent the voltage coil of the reverse current contactor in a known manner weakens in the operating position by connecting a resistor upstream.

Gewöhnlich, geschieht bei Rückstromschützen dieses Schwächen der Anzugspule durch einen kleinen Schalter, der kurz vor der Endstellung des Einschaltankers geöffnet wird. Diese Einrichtung kann man aber bei einem Rückstromschutz nicht immer gebrauchen, weil der kleine Schalter schon geöffnet wird, bevor der Anker mit der vollen Erregung seine Endstellung !erreicht hat.This weakening of the pick-up coil usually occurs with reverse current contactors by a small switch, which opened shortly before the end position of the switch-on armature will. However, this device cannot always be used with reverse current protection, because the small switch is opened before the armature has reached its end position with full excitation!

Will man eine sichere Wirkung des Rückstromschützes erreichen, so muß main dafür sorgen, daß der Anker mit voller Erregung seine Endstellung erreicht und dann erst ein Widerstand vor die Spannungsspule gelegt wird. Diese Zwangsläufigkeit wird erlfLndungsgemäß geschaffen, indem der den Hauptstrom führende, von Hand zu bedienende Steuerschalter beim Einschalten des Ladestromkreises einen Widerstand zur Schwächung der Spannungsspule einschaltet.If you want to achieve a safe operation of the reverse current contactor, then main must be used ensure that the armature reaches its end position with full excitation and only then a Resistance is placed in front of the voltage coil. This inevitability is in accordance with the invention created by the manual control switch that carries the main power when the Charging circuit switches on a resistor to weaken the voltage coil.

Hierdurch erreicht man, daß das Rückstromschütz bei eintretendem Rückstrom stets sogleich auslöst; ferner ist aber hierdurch auch das schädliche Tanzen beseitigt.This ensures that the reverse current contactor always occurs when reverse current occurs immediately triggers; furthermore, this also eliminates the harmful dancing.

Die Erfindung ist in der Zeichnung beispielsweise dargestellt.The invention is shown in the drawing, for example.

Die Batterie kann mit der Dynamomaschine zum Aufladen durch den von Hand zu bedienenden Steuerschalter U in der Stellung L The battery can be charged with the dynamo using the manually operated control switch U in the L position

über 'die Kontakte ι und 2 und die hiermit in Reihe liegenden Kontakte χ und 8 des Rückstromschützes verbunden werden und spieist hierbei das Netz über die Kontakte S und 6. In der Stellung E des Steuerschalters speist die Batterie das Netz über die Kontakte 2 und 3, und in der Stellung M speist die Dynamomaschine das Netz über die Kontakte 3 und 4.are connected via contacts ι and 2 and the contacts χ and 8 of the reverse current contactor, which are in series with them, and feeds the network via contacts S and 6. When the control switch is in position E, the battery feeds the network via contacts 2 and 3 , and in the M position the dynamo feeds the mains via contacts 3 and 4.

Soll die Batterie geladen werden, so wird die Dynamomaschine erregt." Gleichzeitig erhält die Spannungsspule SP des Schützes voDe Erregung, und der Anker N geht von Stellung^ in Stellung>B über. Wenn jetzt der Hebel U in Stellung L zwecks Ladung der Batterie bewegt wird, so drückt die Nase IQ des Hebelst/ den Hebel// in Pfeilrichtung/> zur Seite. Hierdurch wird der Kurzschluß der Kontakte C aufgehoben und der Widerstand W vor die Spannungsspule 'SP gelegt. Zum Festhalten des Ankers N in der Stellung B genügen wenige Amperewindungen. Tritt also Rückstrom ein, so braucht die Stromspule »Sr auch nur sehr wenige Amperewindungen zu entwickeln, damit der Anker iV in Stellung A zurückfällt. Da beim Auftreten von Rückstrom der Hebelt/ in der Stellung auf L verbleibt, bleibt auch der Widerstand W, der vor der Spiannungsspule \SP liegt, weiterhin .eingeschaltet. Gleichzeitig wird aber auch hierdurch der Strom in der Spule SP so geschwächt, daß nicht genügend Amperewindungen vorhanden sind, um den Anker// anzuziehen. Der AnkerN verbleibt also in Stellung^, wodurch das bekannte Tanzen vermieden wird. Bei richtiger Bemessung des Widerstandes W kann man also das bekannte Tanzen des Ankers .4, vermeiden und gleichzeitig den Rückstrom so beeinflussen, daß z. B. schon 2 0/0 Rückstrom geIf the battery is to be charged, the dynamo is excited. "At the same time, the voltage coil SP of the contactor is energized, and the armature N changes from position ^ to position > B. If now the lever U is moved to position L to charge the battery the lug IQ of the lever / pushes the lever // in the direction of the arrow /> to the side. This removes the short circuit of the contacts C and the resistor W is placed in front of the voltage coil 'SP . Sufficient to hold the armature N in position B is If reverse current occurs, the current coil »Sr only needs to develop very few ampere turns so that the armature iV falls back into position A. Since when reverse current occurs, the lever / remains in the L position, the resistance also remains W, which is in front of the voltage coil \ SP , continues to be switched on. At the same time, however, the current in the coil SP is weakened so that there are not enough ampere-turns to d // to tighten the anchor. The anchor N remains in position ^, which avoids the well-known dancing. With the correct dimensioning of the resistance W you can avoid the well-known dancing of the armature .4 and at the same time influence the return current so that, for. B. already 2 0/0 reverse current ge
