Description
In Stromkreisen, welche betriebsmäßig eine sehr hohe Stromstärke führen, ist man oft genötigt, zwei oder mehr Ölschalter parallel zu schalten, weil es unwirtschaftlich und auch konstruktiv schwierig wäre, einen einzigen Schalter für den Gesamtstrom zu bauen. Im allgemeinen wird man mehrere Ölschalter gleicher Größe nehmen und die Anschlußleitungen so verlegen, daß auf die einzelnen Schalter ungefähr gleiche Teilbeträge des Gesamtstromes entfallen. Jeder einzelne Ölschalter muß jedoch so gebaut sein, daß er für sich allein die gesamte Leistung abschalten kann, denn die Stromunterbrechung wird nie an ig allen Ölschaltern genau gleichzeitig erfolgen, und der zuletzt unterbrechende Ölschalter muß die gesamte Schaltleistung bewältigen.One is often in circuits, which carry a very high amperage during operation forced to connect two or more oil switches in parallel because it is uneconomical and also it would be structurally difficult to build a single switch for the entire current. in the In general, you will take several oil switches of the same size and the connecting cables Lay so that the individual switches have approximately the same partial amounts of the total current omitted. However, each individual oil switch must be built in such a way that it can switch off the entire power on its own, because the power interruption will never occur on all oil switches exactly at the same time, and the last interrupting oil switch must cope with the entire switching capacity.
Es ist nun bekannt, daß da, wo sehr hohe Kurzschlußenergien auftreten, die gewöhnao liehen, handelsüblichen Ölschalter nicht mehr ausreichen; .es sind dann sog. Hochleistungsschalter zu wählen, die durch besondere Mittel (Explosionskammern, druckfeste Gehäuse u. dgl.) verstärkt sind und sich demgemaß auch entsprechend teurer stellen.It is now known that where very high short-circuit energies occur, the habitao borrowed, commercially available oil switches are no longer sufficient; Then so-called high-performance switches are to be selected, which are characterized by special Means (explosion chambers, pressure-resistant housing, etc.) are reinforced and accordingly also make correspondingly more expensive.
Um zu vermeiden, daß in solchen Fällen bei Parallelschaltung mehrerer Ölschalter sämtliche Schalter als Hochleistungsschalter gebaut werden müssen, wird erfindungsgemäß folgende Anordnung getroffen: Von den parallel geschalteten Ölschaltern wird nur einer als Hochleistungsschalter ausgebildet und dabei durch geeignete Ausführung des Schaltmechanismus, besondere Ausbildung der Kontakte oder in sonst beliebiger Weise Vorsorge getroffen, daß beim Ausschalten des, gekuppelten Schaltersatzes die Stromtrennung am Hochleistungsschalter zuletzt erfolgt und dieser somit die Bewältigung der Abschaltleistung übernimmt. Eine solche Schaltung ist in der Abbildung angegeben, wo der Hochleistungsschalter α mit zwei normalen Ölschaltern b gekuppelt ist.In order to avoid that in such cases, when several oil switches are connected in parallel, all switches have to be built as high-performance switches, the following arrangement is made according to the invention: Of the oil switches connected in parallel, only one is designed as a high-performance switch and by a suitable design of the switching mechanism, special design of the contacts or Provision is made in any other way that when the coupled switch set is switched off, the power is disconnected last at the high-performance switch and this thus takes over the handling of the breaking capacity. Such a circuit is shown in the figure, where the high-performance switch α is coupled with two normal oil switches b.
Die Kupplung der Ölschalter kann in sonst beliebiger Weise mechanisch oder elektrisch erfolgen, wie hier überhaupt unter Kupplung jede mechanische oder elektrische Einrichtung verstanden werden kann, die eine Zwangläufigkeit der Schaltfolge im Sinne vorstehender Ausführungen bewirkt.The coupling of the oil switch can be mechanical or electrical in any other way take place, as here any mechanical or electrical device under clutch can be understood that an inevitability of the switching sequence in the sense of the above Executions causes.
