Description
Schalteinrichtung für p-phasigen Wechselstrom Die Erfindung betrifft eine Schalteinrichtung für p-phasigen Wechselstrom, deren p mechanische Schaltstrecken zeitlich versetzt gegeneinanderschalten. Erfindungsgemäß ist eine Diode vorhanden, welche auf die einzelnen Phasen innerhalb der Zeiträume umgeschaltet wird, da die mechanischen Schaltstrecken gegeneinander versetzt schalten, so daß jeweils vor dem Ein- bzw. Ausschalten der Schaltstrecke einer Phase die Diode parallel liegt.Switching device for p-phase alternating current The invention relates to a switching device for p-phase alternating current, its p mechanical switching paths Switch against each other at different times. According to the invention there is a diode which is switched to the individual phases within the time periods since the switch mechanical switching paths offset from one another, so that in each case before the switching on or off of the switching path of a phase the diode is parallel.
Es sind bereits Vorrichtungen zum Schalten von Mehrphasenstrom bekannt, in denen nicht alle Phasen gleichzeitig schalten. Durch sie wird jedoch keine Lehre erteilt, den Stromkreis auch dann lichtbogenfrei zu unterbrechen, wenn sich der Strom nicht gerade im Nulldurchgang befindet.Devices for switching multi-phase current are already known, in which not all phases switch at the same time. However, there is no teaching through them issued to interrupt the circuit without arcing even if the Current is not exactly in the zero crossing.
Der Gegenstand der Erfindung bietet gegenüber den bekannten Anordnungen den Vorteil, die mechanischen Schaltstrecken während des Zeitraumes einer vollen Halbwelle lichtbogenfrei öffnen zu können. Im Gegensatz dazu steht für eine lichtbogenfreie Unterbrechung der Kontakte nur ein Zeitpunkt, nämlich der Nulldurchgang des Stromes, zur Verfügung. Dadurch, daß es weiterhin möglich ist, mit nur einer Diode mehrere Schaltstrecken lichtbogenfrei zu unterbrechen, ergibt sich eine hohe Wirtschaftlichkeit der Schalteinrichtung.The object of the invention offers over the known arrangements the advantage of the mechanical switching distances during the period of a full Half-wave to be able to open without arcing. In contrast, stands for an arc-free Interruption of the contacts only for one point in time, namely the zero crossing of the current, to disposal. Because it is still possible to use several diodes with just one Interrupting switching paths without arcing results in a high level of cost-effectiveness the switching device.
Die Verwendung von Dioden parallel zu Unterbrechungsstrecken von elektrischen Schaltern ist an sich bekannt.The use of diodes in parallel with interruption lines of electrical Switches is known per se.
An Hand einer Zeichnung sei ein schematisches Ausführungsbeispiel der Erfindung dargestellt. Ein Drehstromsystem u, v, w wird über die mechanischen Trennstrecken 1, 2, 3, die auch Mehrfachunterbrechung aufweisen können, auf ein Verbrauchersystem u', v', w' geschaltet. Die Darstellung geht von der bekannten Tatsache aus, daß bei einem p-phasigen System die zuletzt geschaltete Phase auch ohne Parallelschelten einer Diode lichtbogenfrei unterbrochen werden kann.A schematic exemplary embodiment of the invention is illustrated with the aid of a drawing. A three-phase system u, v, w is switched to a consumer system u ', v', w 'via the mechanical isolating paths 1, 2, 3, which can also have multiple interruptions. The illustration is based on the known fact that, in a p-phase system, the last switched phase can be interrupted without an arc without parallel switching a diode.
Für die beiden Trennstrecken 1 und 2 steht lediglich ein einziger Diodensatz 8 zur Verfügung, welcher durch Umschalter 9 und 10 nacheinander parallel zur Trennstrecke 1 oder zur Trennstrecke 2 geschaltet wird. Durch gestrichelte Linien ist angedeutet, daß notfalls dieser Satz auch auf die Phase 3 umgeschaltet werden könnte. Außerdem sind Leerkontakte 11 und 12 vorgesehen, welche die Zellen im ausgeschalteten Zustand der Schaltstrecken 1 bis 3 spannungslos machen. Diese Ausführung der Erfindung läßt sich nur bei mechanischen Schaltern verwenden, deren Schaltstrecken 1 bis 3 zeitlich so weit gegeneinander versetzt geschaltet werden, daß in diesen Zeiträumen die Umschaltung des Diodensatzes 8 mit den Schaltern 9 und 10 erfolgen kann. Besonders einfach wird auch diese Ausführung der Erfindung, wenn synchrone Schrittschaltwerke zur Betätigung der Schaltstrecken 1, 2 und 3 und der Umschalter 9 und 10 verwendet werden.Only a single set of diodes 8 is available for the two isolating distances 1 and 2, which are switched one after the other in parallel to isolating distance 1 or to isolating distance 2 by changeover switches 9 and 10. Dashed lines indicate that this sentence could also be switched to phase 3 if necessary. In addition, empty contacts 11 and 12 are provided, which de-energize the cells when the switching paths 1 to 3 are switched off. This embodiment of the invention can only be used with mechanical switches, the switching paths 1 to 3 of which are switched so far offset in time that the switching of the diode set 8 with the switches 9 and 10 can take place in these time periods. This embodiment of the invention is also particularly simple if synchronous stepping mechanisms are used to actuate the switching paths 1, 2 and 3 and the changeover switches 9 and 10.
