Description

Die Erfindung betrifft ein Modul für einen Drehantrieb eines elektrischen Schalters, einen elektrischen Schalter mit solch einem Modul, sowie ein Verfahren zum Schalten eines elektrischen Schalters.The invention relates to a module for a rotary drive of an electrical switch, an electrical switch with such a module, and a method for switching an electrical switch.

Bei ausgeschalteten Kompaktleistungsschaltern soll typischerweise der Stromkreis eines Unterspannungsauslösers allpolig mit Hilfsschaltern von der Spannungsquelle getrennt sein. Dabei muss gewährleistet sein, dass beim Verlassen der "OFF"-Stellung des Kompaktleistungsschalter-Handles der Stromkreis des Unterspannungsauslösers wieder mit der Spannungsquelle verbunden ist.When the molded case circuit breakers are switched off, typically the circuit of an undervoltage release should be disconnected from the voltage source with all-pole auxiliary switches. It must be ensured that when leaving the "OFF" position of the molded case circuit breaker handle, the circuit of the undervoltage release is reconnected to the voltage source.

Zur Lösung dieser Problematik können beispielsweise die Hilfsschalter neben dem Unterspannungsauslöser in Kompaktleistungsschalter-Taschen eingebaut sein. Dieses Konzept benötigt aber ein zusätzliches Volumen in den Kompaktleistungsschalter-Taschen auf Kosten von Platz für zusätzliches internes Zubehör. Auch muss ein bestimmter Wegabstand zwischen dem Verlassen der "OFF"-Stellung des Kompaktleistungsschalters und der Unterspannungsauslöser-"Verklinkt"-Stellung vorhanden sein.To solve this problem, for example, the auxiliary switch can be installed next to the undervoltage release in compact circuit breaker pockets. However, this concept requires an extra volume in the molded case circuit breaker pockets at the expense of space for additional internal accessories. There must also be a certain distance between leaving the "OFF" position of the molded case circuit breaker and the undervoltage release "latched" position.

Des Weiteren können vom Kunden Drehantriebe nachgerüstet werden. Dieses Konzept erfordert jedoch ein zusätzliches Volumen im Drehantrieb und das Vorhandensein eines bestimmten Wegabstandes zwischen dem Verlassen der "OFF"-Stellung des Kompaktleistungsschalters und der Unterspannungsauslöser-"Verklinkt"-Stellung.Furthermore, the customer can retrofit rotary actuators. However, this concept requires an additional volume in the rotary drive and the presence of a certain distance between leaving the "OFF" position of the molded case circuit breaker and the undervoltage release "latched" position.

Es ist daher die Aufgabe der Erfindung, eine alternative Lösung zum Gewährleisten des Einschaltens der Spannungsversorgung eines Unterspannungsauslösers zur Verfügung zu stellen.It is therefore the object of the invention to provide an alternative solution for ensuring the switching on of the power supply of an undervoltage release.

Diese Aufgabe wird erfindungsgemäß durch das Modul für einen Drehantrieb eines elektrischen Schalters gemäß Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Moduls sind in den Unteransprüchen 2 bis 8 angegeben. Die Aufgabe wird ebenfalls erfindungsgemäß durch den elektrischen Schalter mit einem Modul gemäß Anspruch 9 gelöst. Ebenso wird die Aufgabe erfindungsgemäß durch das Verfahren zum Schalten eines elektrischen Schalters gemäß Anspruch 10 gelöst.This object is achieved by the module for a rotary drive of an electrical switch according to claim 1. Advantageous embodiments of the module according to the invention are specified in the subclaims 2 to 8. The object is also achieved according to the invention by the electrical switch with a module according to claim 9. Likewise, the object is achieved by the method for switching an electrical switch according to claim 10.

Das Modul gemäß Anspruch 1 für einen Drehantrieb eines elektrischen Schalters, wobei der Drehantrieb mittels eines Dreh-Handles betätigt wird, indem das Dreh-Handle eine Drehwelle des Drehantriebs zwischen zumindest zwei Schalterstellungen bewegt, umfasst mindestens einen Hilfsschalter, wobei das Modul zwischen dem Drehantrieb und dem Dreh-Handle montierbar ist, wobei der mindestens eine Hilfsschalter bei einer Drehbewegung des Dreh-Handles vorauseilend vor Erreichung einer der Schalterstellungen geschaltet wird, wenn das Modul zwischen dem Drehantrieb und dem Dreh-Handle montiert ist.The module according to claim 1 for a rotary drive of an electrical switch, wherein the rotary drive is actuated by a rotary handle by the rotary handle moves a rotary shaft of the rotary drive between at least two switch positions comprises at least one auxiliary switch, wherein the module between the rotary drive and the rotary handle is mountable, wherein the at least one auxiliary switch is preceded by a rotational movement of the rotary handle before reaching one of the switch positions, when the module is mounted between the rotary drive and the rotary handle.

Das erfindungsgemäße Modul belegt keinen Bauraum im Unterspannungsauslöser, Kompaktleistungsschalter oder Drehantrieb. Durch das Entkoppeln der Voreilung durch das Modul ist erst eine kompakte Konstruktion des Kompaktleistungsschalters bzw. des Zubehörs durch das nahe Heranlegen der Unterspannungsauslöser-"Verklinkt"-Stellung an die "OFF"-Stellung des Kompaktleistungsschalters möglich.The module according to the invention occupies no space in the undervoltage release, molded case circuit breaker or rotary drive. By decoupling the lead through the module, a compact design of the molded case circuit breaker or accessory is possible only by bringing the undervoltage release "latched" position close to the "OFF" position of the molded case circuit breaker.

In einer Ausgestaltung des erfindungsgemäßen Moduls wird der mindestens eine Hilfsschalter geschaltet entweder von "betätigt" zu "nicht betätigt" oder von "nicht betätigt" zu "betätigt".In one embodiment of the module according to the invention, the at least one auxiliary switch is switched either from "actuated" to "not actuated" or from "not actuated" to "actuated".

In einer weiteren Ausgestaltung umfasst das Modul eine Kurvenscheibe und eine mit der Kurvenscheibe gekoppelte Betätigerscheibe.In a further embodiment, the module comprises a cam disc and an actuator disc coupled to the cam disc.

In einer weiteren Ausgestaltung sind eine Kulisse in der Kurvenscheibe und ein in der Kulisse laufender Pin an der Betätigerscheibe angebracht. Alternativ sind eine Kulisse in der Betätigerscheibe und ein in der Kulisse laufender Pin an der Kurvenscheibe angebracht.In a further embodiment, a link in the cam and a pin running in the gate are attached to the actuator disc. Alternatively, a backdrop in the actuator disc and a running pin in the backdrop are attached to the cam.

In einer Ausgestaltung bringt eine Rückstellfeder die Kurvenscheibe und die Betätigerscheibe in eine vordefinierte Positionierung zueinander.In one embodiment, a return spring brings the cam and the actuator disc in a predefined position to each other.

In einer weiteren Ausgestaltung wird der mindestens eine Hilfsschalter durch eine radiale Verdickung an der Kurvenscheibe geschaltet.In a further embodiment, the at least one auxiliary switch is switched by a radial thickening on the cam.

In einer weiteren Ausgestaltung umfasst das Modul zwei Hilfsschalter, die bei einer Drehbewegung des Dreh-Handles vorauseilend vor Erreichung einer der Schalterstellungen nacheinander geschaltet werden, wenn das Modul zwischen dem Drehantrieb und dem Dreh-Handle montiert ist. Vorteilhaft hierbei ist, dass durch die Integration von mehreren Hilfsschaltern im Modul eine größere Varianz von voreilenden Hilfsschaltern im System möglich ist.In a further embodiment, the module comprises two auxiliary switches, which are switched in succession before reaching one of the switch positions in a rotational movement of the rotary handle, when the module is mounted between the rotary drive and the rotary handle. The advantage here is that a greater variance of leading auxiliary switches in the system is possible by the integration of multiple auxiliary switches in the module.

Der elektrische Schalter gemäß Anspruch 9 umfasst ein erfindungsgemäßes Modul und einen Drehantrieb, der mittels eines Dreh-Handles betätigt wird, indem das Dreh-Handle eine Drehwelle des Drehantriebs zwischen zumindest zwei Schalterstellungen bewegt, und wobei das Modul zwischen dem Drehantrieb und dem Dreh-Handle montiert ist.The electric switch according to claim 9 comprises a module according to the invention and a rotary drive, which is actuated by means of a rotary handle by the rotary handle moves a rotary shaft of the rotary drive between at least two switch positions, and wherein the module between the rotary drive and the rotary handle is mounted.

Das Verfahren zum Schalten des elektrischen Schalters gemäß Anspruch 10 umfasst einen erfindungsgemäßen elektrischen Schalter mit montiertem Drehantrieb, an dem ein erfindungsgemäßes Modul montiert ist und wobei am Modul das Dreh-Handle montiert ist, mit den Schritten:

  • Drehen des Dreh-Handle in Richtung einer Schalterstellung, so dass der mindestens eine Hilfsschalter betätigt wird, und danach
  • weiteres Drehen des Dreh-Handle in die Schalterstellung.
The method for switching the electrical switch according to claim 10 comprises an electric switch with mounted rotary drive according to the invention, to which an inventive Module is mounted and where the rotary handle is mounted on the module, with the steps:
  • Turning the rotary handle in the direction of a switch position, so that the at least one auxiliary switch is actuated, and thereafter

Figur 1 ist eine Prinzipskizze des erfindungsgemäßen Moduls 100. Weiter ist in Figur 1 der Drehantrieb 200 und der Unterspannungsauslöser 300 dargestellt. Die Handhabe 310 eines elektrischen Schalters wird in einer linearen Bewegung von der "ON"-Stellung in die "OFF"-Stellung bzw. umgekehrt bewegt zum Einschalten oder Ausschalten des elektrischen Stromes. Der Drehantrieb 200 übersetzt die Drehbewegung eines Dreh-Handles 10 in die lineare Bewegung des Handles 310 des elektrischen Schalters. Dazu kann beispielsweise ein Getriebe 220 vorgesehen sein, und ein Schlitten 230, der die Handhabe 310 des elektrischen Schalters bewegt. FIG. 1 is a schematic diagram of the inventive module 100. Next is in FIG. 1 the rotary actuator 200 and the undervoltage release 300 shown. The handle 310 of an electrical switch is moved in a linear movement from the "ON" position to the "OFF" position or vice versa to turn on or off the electric current.
