Description
Die Erfindung bezieht sich auf eine Schaltgeräteeinheit mit einem Schaltgerät mit einem ersten Betätigungselement und mit einem an das Schaltgerät angekoppelten voreilenden Hilfsschalter mit einem zweiten Betätigungselement.The invention relates to a switching device unit a switching device with a first actuator and with a leading auxiliary switch coupled to the switching device with a second actuator.
Eine gattungsgemäße Schaltgeräteeinheit ist von Schaltgeräteherstellern beziehbar. Dabei ist das Schaltgerät ein Leistungsschalter, an dessen Rand als Betätigungselement ein Wippknebel eingebaut ist. Der Wippknebel ermöglicht das Umgreifen am Drehknebel eines Unterspannungsauslösers mit voreilendem Hilfsschalter. Der Drehknebel ist mit einem voreilenden Spiel versehen, so daß zunächst der voreilende Hilfsschalter eingeschaltet wird, bevor der Einschaltvorgang des Leistungsschalters beginnt. Die Drehachsen vom Wippknebel des Leistungsschalters und vom Drehknebel des voreilenden Hilfsschalters liegen dabei auf einer Linie.A generic switchgear unit is from switchgear manufacturers obtainable. The switchgear is a circuit breaker, on its edge as an actuator Rocker gag is installed. The rocker toggle allows you to reach around on the rotary knob of an undervoltage release with leading Auxiliary switch. The rotary knob is with a leading Match provided so that first the leading auxiliary switch is switched on before the switching on of the Circuit breaker begins. The axes of rotation of the rocker switch of the Circuit breaker and the rotary switch of the leading auxiliary switch lie on a line.
Der Erfindung liegt die Aufgabe zugrunde, eine Schaltgeräteeinheit der obengenannten Art zu schaffen, die sich durch einen einfachen Einschaltvorgang mit möglichst nur einer Handbewegung auszeichnet.The invention has for its object a switching device unit of the type mentioned above, which is characterized by a simple switch-on process with only one hand movement if possible distinguished.
Die Aufgabe wird dadurch gelöst, daß das zweite Betätigungselement als Schieber mit einer Kulisse ausgeführt ist, die mit einem Umlenkhebel in Eingriff steht und die bei Betätigung des Schiebers die Position des Umlenkhebels solchermaßen bestimmt, daß der Umlenkhebel einen mit ihm in Wirkverbindung stehenden Kontaktträger in einer ersten Betätigungsphase des Schiebers in die EIN-Stellung von beweglichen Kontakten mit Festkontakten des voreilenden Hilfsschalters bringt und in einer folgenden zweiten Betätigungsphase des Schiebers die EIN-Stellung des Umlenkhebels beibehalten wird und zugleich der Schieber das erste Betätigungselement betätigt.The object is achieved in that the second actuating element is designed as a slide with a backdrop that with a lever is engaged and when actuated of the slide determines the position of the bell crank in such a way that the bell crank one in operative connection with it standing contact carrier in a first actuation phase of the Slider in the ON position of moving contacts with Fixed contacts of the leading auxiliary switch brings and in a subsequent second actuation phase of the slide ON position of the bell crank is maintained and at the same time the slide actuates the first actuating element.

In FIG 1 ist eine aus einem Schaltgerät 1 und einem Unterspannungsauslöser
mit voreilenden Hilfsschalter 2 zusammengesetzte
Schaltgeräteeinheit dargestellt. Das Betätigungselement
des Schaltgeräts 1 ist als Drehwippe 3 ausgeführt, deren
Drehachse hier quer zu den beiden Anschlußreihen 4 gelegen
ist, von denen hier nur die Vordere sichtbar ist. Das Betätigungselement
des Hilfsschalters 2 ist als Schieber 5 mit einer
Druckfläche 6 ausgeführt, die die Drehwippe 3 zumindest
teilweise überragt. Die Druckfläche 6 hat einen Abstand 7 zur
Drehwippe 3. Der Abstand 7 stellt den voreilenden Weg dar, um
den sich der Schieber 5 der Drehwippe 3 annähern muß, bevor
er die Drehwippe 3 betätigt. Zur Überwindung dieses Abstands
7 weist die Betätigungsrichtung des Schiebers 5 eine Komponente
auf, die parallel zur Anbauwand des Hilfsschalters 2
liegt. Eine weitere Komponente der Betätigungsrichtung des
Schiebers 5 liegt in einer Ebene parallel zur Frontwand 8 des
Schaltgeräts 1. Diese erleichtert den Einschaltvorgang bei
Betätigung der Drehwippe 3.In FIG 1 is one of a switching device 1 and an undervoltage release
assembled with leading
In FIG 2 ist eine Innenansicht des voreilenden Hilfsschalters
2 dargestellt, der ein Elektromagnetsystem, mehrere Anschlüsse
9, Festkontakte 10, einen Kontaktträger 11 mit beweglichen
Kontakten 12, einen Umlenkhebel 13 sowie den bereits genannten
Schieber 5 umfaßt. Der Umlenkhebel 13 steht einerseits
mit dem Kontaktträger 11 in Wirkverbindung und greift andererseits
in eine Kulisse 14 am Schieber 5 ein. Diese Kulisse
14 weist zwei längliche Konturabschnitte 15 und 16 auf, die
hier im rechten Winkel zueinander stehen, jedoch auch in einem
Winkel von 80 bis 100 °C liegen können. Durch Drücken des
Schiebers 5 gleitet der Umlenkhebel 13 zunächst in dem parallel
zur Frontwand des Hilfsschalters 2 liegenden Konturabschnitt
15 entlang und dreht sich zugleich unter Mitnahme des
Kontaktträgers 11. Bis zum Ende dieser ersten Betätigungsphase
läuft der am Umlenkhebel 13 rückseitige, hier nicht sichtbare
Zapfen 17 bis zum Richtungswechsel und drückt den Kontaktträger
11 in die EIN-Stellung, in der die beweglichen
Kontakte 12 mit den Festkontakten 10 kontaktieren. Durch eine
kleine Vertiefung am Ende der Längsführung wird gewährleistet,
daß der Schieber 5 seine EIN-Stellung auch durch Einwirkung
von Vibration und Stößen nicht ändert. In der zweiten
Betätigungsphase des Schiebers 5 gleitet der Zapfen 17 in dem
zweiten Konturabschnitt 16 entlang, wobei der Umlenkhebel 13
unverändert seine Schließstellung der Kontakte 10,12 beibehält.
Die zweite Betätigungsphase des Schiebers 5 beginnt also
im Richtungswechselpunkt 18, in dem zugleich die Druckfläche
6 nach Durchlaufen des Abstandes 7 die Drehwippe 3 erreicht
(siehe FIG 1). In der zweiten Betätigungsphase wird
die Drehwippe 3 durch die Druckfläche 6 betätigt.In Figure 2 is an interior view of the leading
Mit dem Schieber 5 wird also durch bloßes Drücken die Einschaltung
des voreilenden Hilfsschalters 2 und des Schaltgeräts
1 mit der Drehwippe 3 erreicht.With the
Beim Ausschalten hebt die Federkraft der Drehwippe 3 den Betätigungsschieber
5 bis zum Richtungswechselpunkt 18 der Zapfenführung
heraus. Danach gelangt dieser durch Einwirkung einer
Drehfeder 19 über den Umlenkhebel 13 in seine endgültige
Ruhelage.When switched off, the spring force of the
