Description

Die Erfindung betrifft eine Sicherungseinrichtung für e-elektrische Vorrichtungen nach dem Oberbegriff des Anspruchs 1.The invention relates to a safety device for e-electric devices according to the preamble of claim 1.

Elektrische Vorrichtungen insbesondere Vorrichtungen, an denen Hochspannung oder hohe Stromstärken anliegen, sind üblicherweise mit einer Sicherheitseinrichtung versehen, die ein Abschalten des Stromes gewährleistet. Diese Sicherheitseinrichtungen können selbsttätig auslösend oder manuell auslösbar gestaltet sein.Electrical devices, in particular devices to which high voltage or high current levels are applied, are usually provided with a safety device which ensures a switching off of the current. These safety devices can be designed to trigger automatically or triggered manually.

Soll eine manuelle Auslösung zumindest optional vorgesehen sein, kann ein Hebel vorgesehen sein, der von Hand in eine Aus-Stellung bringbar ist. Bei Leistungsschutzschaltern und Sicherungseinrichtungen für Leistungsschutzschalter ist hierzu häufig ein verschwenkbarer Haupthebel vorgesehen.If a manual release is to be provided at least optionally, a lever can be provided which can be brought by hand into an off position. For circuit breakers and circuit breakers for circuit breakers this is often a pivoting main lever provided.

Um beim Arbeiten an der ausgeschalteten Vorrichtung zu gewährleisten, dass der Haupthebel nicht versehentlich in die Ein-Stellung gebracht wird, sind häufig farbliche Markierungen oder Warnhinweise angebracht. Es besteht jedoch immer die Gefahr, dass der Hauptschalter dennoch versehentlich in die Ein-Stellung gebracht wird.In order to ensure that the main lever is not inadvertently brought to the on position when working on the switched-off device, colored markings or warnings are often attached. However, there is always the danger that the main switch is still inadvertently brought into the on position.

Aus der DE 196 06 271 A ist eine Sicherungseinrichtung für eine elektrische Vorrichtung, nämlich ein Schutzschalter, mit einer Verriegelungsvorrichtung gegen ein unbeabsichtigtes Einschalten bekannt, die einen verschwenkbaren Haupthebel aufweist, der zwischen einer Ein-Stellung und einer Aus-Stellung verschwenkbar ist. Dieser Schalter weist einen Betätigungsgriff auf, der auf einer Schaltwelle frei drehbar ist, wobei der Betätigungsgriff mit einer Scheibe in Wirkverbindung steht und eine Drehung des Betätigungsgriffs auf diese Scheibe und von dieser auf die Schaltwelle übertragbar ist. Die Verriegelungsvorrichtung weist einen Schieber zum Blockieren der Einschaltbewegung der Schaltwelle auf und wirkt zur Verriegelung derselben auf die Scheibe ein.From DE 196 06 271 A a safety device for an electrical device, namely a circuit breaker, with a locking device against inadvertent switching is known, which has a pivotable main lever which is pivotable between an on position and an off position. This switch has an actuating handle which is freely rotatable on a switching shaft, wherein the actuating handle is in operative connection with a disc and a rotation of the actuating handle on this disc and from this to the switching shaft is transferable. The locking device has a slide for blocking the switch-on movement of the switching shaft and acts to lock the same on the disc.

Aus der EP 1 137 025 A2 ist eine Sicherungseinrichtung für elektrische Vorrichtungen bekannt, die einen verschwenkbaren Haupthebel hat, der zwischen einer Ein-Stellung und einer Aus-Stellung verschwenkbar ist. Dieser Haupthebel weist eine Kontur auf, die einen Arretierabschnitt hat, der in der Aus-Stellung des Haupthebels mit einem Sicherungsabschnitt eines Sicherungshebels so in Anlage bringbar ist, dass ein Verschwenken des Haupthebels in der Aus-Stellung durch die Anlage der Abschnitte unmöglich ist.From EP 1 137 025 A2 a safety device for electrical devices is known, which has a pivotable main lever which is pivotable between an on position and an off position. This main lever has a contour which has a locking portion which is engageable in the off position of the main lever with a securing portion of a safety lever so that pivoting of the main lever in the off position by the system of sections is impossible.

Mit der Erfindung soll eine Sicherungseinrichtung geschaffen werden, die bei Arbeiten an einer elektrischen Vorrichtung eine hohe Sicherheit gewährleistet.With the invention, a safety device is to be created, which ensures a high level of safety when working on an electrical device.

Durch die Merkmale des Anspruchs 1 wird eine derartige Sicherungseinrichtung geschaffen. Diese Sicherungseinrichtung für eine elektrisches Vorrichtung weist einen verschwenkbaren Haupthebel auf, der zwischen einer Ein-Stellung und einer Aus-Stellung verschwenkbar ist. Der Haupthebel weist eine Kontur auf, die einen Arretierabschnitt umfasst, der mit einem Sicherungsabschnitt eines Sicherungshebels in Anlage bringbar ist, wobei die zwei Abschnitte derart gestaltet sind, dass diese sich in Anlage befinden, wenn sich der Haupthebel in der Aus-Stellung befindet, und in dieser Stellung ein Verschwenken des Haupthebels unmöglich machen.By the features of claim 1 such a security device is provided. This safety device for an electrical device has a pivotable main lever which is between an on position and an off position is pivotable. The main lever has a contour that includes a locking portion that is engageable with a securing portion of a safety lever, wherein the two portions are designed such that they are in abutment when the main lever is in the off position, and In this position make pivoting of the main lever impossible.

Wenn sich die Sicherungseinrichtung in der Betriebsstellung und der Haupthebel in der Ein-Stellung befindet ist dagegen ein Verschwenken des Haupthebels aus der Ein-Stellung in die Aus-Stellung ohne weiteres möglich.When the safety device is in the operating position and the main lever in the on position, however, a pivoting of the main lever from the on position to the off position readily possible.

Die Kontur des Haupthebels ist weiterhin mit einem Betriebsabschnitt versehen, der im Betriebszustand, also in der Ein-Stellung des Haupthebels mit einem Freigabeabschnitt des Sicherungshebels so zusammenwirkt, so dass der Sicherungshebel in dieser Stellung nicht bewegt werden kann. Eine Bewegung des Sicherungshebels ist erst möglich, wenn der Haupthebel in die Aus-Stellung gebracht wurde und dadurch der Betriebsabschnitt von dem Freigabeabschnitt des Sicherungshebels gelöst wurde. In dieser Stellung kann der Sicherungshebel in die Sicherungsstellung gebracht werden in der, wie beschrieben, der Sicherungsabschnitt des Sicherungshebels mit dem Arretierabschnitt des Haupthebels zusammenwirkt und ein Zurückverschwenken des Haupthebels aus der Aus-Stellung in die Ein-Stellung unmöglich macht.The contour of the main lever is further provided with an operating portion which cooperates in the operating state, ie in the on position of the main lever with a release portion of the safety lever so that the safety lever can not be moved in this position. A movement of the safety lever is only possible when the main lever has been brought into the off position and thereby the operating portion has been released from the release portion of the safety lever. In this position, the safety lever can be brought into the securing position in which, as described, the securing portion of the safety lever cooperates with the locking portion of the main lever and makes a pivoting back of the main lever from the off position to the on position impossible.

Zweckmäßig ist der Betriebsabschnitt der Kontur des Haupthebels im wesentlichen rund ausgebildet, da auf diese Weise eine Verschwenkbarkeit des Haupthebels einfach ermöglicht wird. Der Abschnitt ist vorteilhaft konzentrisch zur Schwenkachse des Haupthebels ausgebildet ist, so dass bei Verschwenkung des Haupthebels eine Drehung des Abschnitts erfolgt, ohne dass sich die Anlageverhältnisse am Freigabeabschnitt des Sicherungshebels ändern.Suitably, the operating portion of the contour of the main lever is substantially round, as in this way a pivotability of the main lever is easily possible. The portion is advantageously formed concentrically to the pivot axis of the main lever, so that at Pivoting the main lever, a rotation of the section takes place, without changing the investment conditions on the release portion of the safety lever.

Der Arretierabschnitt des Haupthebels ist zweckmäßig unrund ausgebildet, um zu erreichen, dass bei Anlage dieses Abschnitts am Sicherungsabschnitt des Sicherungshebels ein Verschwenken des Haupthebels nicht möglich ist. Zweckmäßig ist sowohl der Arretierabschnitt als auch der Sicherungsabschnitt im wesentlichen gerade ausgebildet, so dass ein Verschwenken nicht möglich ist. Es sind aber auch andere Gestaltungen möglich, solange die beiden Abschnitte so zusammenwirken, dass ein Verschwenken des Arretierabschnitts des Haupthebels in dieser Stellung nicht möglich ist.The locking portion of the main lever is expediently formed out of round, in order to achieve that upon application of this section on the securing portion of the safety lever pivoting of the main lever is not possible. Suitably, both the locking portion and the securing portion is formed substantially straight, so that pivoting is not possible. However, other configurations are possible as long as the two sections cooperate so that pivoting of the locking portion of the main lever in this position is not possible.

Sowohl die Kontur des Haupthebels als auch der Sicherungshebel können noch weitere Abschnitte aufweisen. Die Anordnung der Abschnitte ist nachrangig, solange in der Aus-Stellung des Haupthebels ein Verschwenken desselben durch eine entsprechenden Eingriff des Arretierabschnitts mit dem Sicherungsabschnitts verhindert wird und in der Betriebsstellung ein Verschwenken ermöglicht wird. Soll der Sicherungshebel nur in der Aus-Stellung des Haupthebels in die Sicherungsstellung bewegbar sein, muss ein entsprechendes Zusammenwirken des Betriebsabschnitt und des Freigabeabschnitts des Sicherungshebels gewährleistet sein.Both the contour of the main lever and the safety lever may have more sections. The arrangement of the sections is subordinate as long as in the off position of the main lever pivoting thereof is prevented by a corresponding engagement of the locking portion with the securing portion and in the operating position pivoting is enabled. If the securing lever can only be moved into the securing position in the off position of the main lever, a corresponding interaction of the operating section and the release section of the securing lever must be ensured.

Der Sicherungshebel kann drehbar oder linear verschieblich gelagert sein. Zur verschieblichen Lagerung kann in einem mittleren Bereich des Sicherungshebels eine Ausnehmung vorgesehen sein, in die zumindest ein Lagerzapfen eingreift.The safety lever can be mounted rotatably or linearly displaceable. For displaceable mounting may be provided in a central region of the safety lever, a recess into which engages at least one bearing pin.

Der Sicherungshebel kann zumindest einen Anschlag aufweisen, der zumindest eine Endposition des Sicherungshebels und damit auch die Stellung der Abschnitte des Sicherungshebels relativ zum Haupthebel festlegt. Hierzu können auch Rastnasen und dergleichen vorgesehen sein. Der Sicherungshebel kann arretierbar sein. Hierzu können unterschiedliche Gestaltungen vorgesehen sein. Der Sicherungshebel kann über eine Öffnung verfügen, in die ein Schloss oder dergleichen zur Arretierung des Sicherungshebels eingesetzt werden kann.The safety lever may have at least one stop which defines at least one end position of the safety lever and thus also the position of the portions of the safety lever relative to the main lever. For this purpose, locking lugs and the like may be provided. The safety lever can be locked. For this purpose, different designs may be provided. The safety lever may have an opening into which a lock or the like can be used to lock the safety lever.

Der Haupthebel 1 ist um eine Achse 13 verschwenkbar gelagert und verfügt im oberen Bereich über ein Griffstück 14. Diesem Griffstück 14 gegenüberliegend im unteren Bereich befindet sich ein Betriebsabschnitt 12, der rund ausgebildet ist. Bei diesem Ausführungsbeispiel ist die äußere Fläche des Betriebsabschnitts 12 konzentrisch zur Achse 13 vorgesehen und erstreckt sich über einen Winkelbereich von etwa 140°.In Figure 1, the securing device is shown in the operating position. The main lever 1 is in this position in the on position shown. The main lever 1 is pivotally mounted about an axis 13 and has in the upper region via a handle 14. This handle 14 opposite in the lower area is an operating portion 12 which is round. In this embodiment, the outer surface of the operating portion 12 is provided concentric with the axis 13 and extends over an angular range of about 140 °.

Auf der in der Darstellung rechten Seite geht dieser Betriebsabschnitt 12 in das Griffstück 14 über. Auf der linken Seite schließt sich dem Betriebsabschnitt 12 ein gerader Arretierabschnitt 11 an, der wiederum ebenfalls in das Griffstück 14 übergeht.On the right side in the illustration of this operating section 12 is in the handle 14 via. On the left side, the operating section 12 is followed by a straighter Arresting section 11, which in turn also merges into the handle 14.

Der Betriebsabschnitt 12 ist in der in Figur 1 gezeigten Stellung in Anlage oder Eingriff mit einem Freigabeabschnitt 22 eines Sicherungshebels 20. Bei dem Sicherungshebel 20 handelt es sich um einen verschiebbaren Hebel, der mittels einer Linearführung verschieblich gelagert ist. Der genannten Freigabeabschnitt 22 weist die Form eines muldenartigen Rücksprungs auf, dessen Anlagefläche, die mit dem Betriebsabschnitt 12 in Anlage kommt, im wesentliche rund ausgebildet ist. Bei dem dargestellten Sicherungshebel 20 ist auf beiden Seiten des Freigabeabschnitts 22 ein gerader Abschnitt vorgesehen. Der in der Darstellung rechte Abschnitt stellt den Sicherungsabschnitt 21 dar. Im linken Teil des Sicherungshebels 20 ist eine Ausnehmung 24 in Form einer Bohrung vorgesehen und am linken Ende des Sicherungshebels 20 ein Griff 25.The operating portion 12 is in the position shown in Figure 1 in engagement or engagement with a release portion 22 of a safety lever 20. The safety lever 20 is a displaceable lever which is slidably mounted by means of a linear guide. The said release portion 22 has the shape of a trough-like recess, the contact surface, which comes into abutment with the operating portion 12, is formed substantially round. In the illustrated safety lever 20, a straight portion is provided on both sides of the release portion 22. The right in the representation section represents the securing portion 21. In the left part of the safety lever 20, a recess 24 is provided in the form of a bore and at the left end of the safety lever 20, a handle 25th

Folgend wird die Funktionsweise der Sicherungsvorrichtung anhand einer Überführung des Haupthebels 1 aus der in Figur 1 gezeigten Ein-Stellung in die in Figur 2 gezeigte Aus-Stellung erläutert.The mode of operation of the securing device is explained below on the basis of a transfer of the main lever 1 from the on position shown in FIG. 1 into the off position shown in FIG.

Aufgrund der Gestaltung des Betriebsabschnitts 11 und des Freigabeabschnitts 22 ist ein Verschwenken des Haupthebels 1 aus der in Figur 1 gezeigten Stellung nach links also in die in Figur 2 gezeigte Stellung ohne weiteres möglich. Befindet sich der Haupthebel 1 in der in Figur 2 gezeigten Aus-Stellung, ist der Betriebsabschnitt 12 nicht länger in Anlage mit dem Freigabeabschnitt 22. Der Sicherungshebel 2 wird in dieser Stellung zwar durch die in Figur 2 zu sehende Rastnase 3, die mit der Unterseite des Sicherungshebels 2 zusammenwirkt, leicht gehalten, der Sicherungshebel 2 kann aber ohne weiteres am Griff 25 nach links oben gezogen werden und somit in die in Figur 2 gezeigte Stellung gebracht werden. Zweckmäßig ist ein Anschlag oder dergleichen vorgesehen, der die Endposition festlegt. In dieser Stellung ist der gerade Sicherungsabschnitt 21 des Sicherungshebels 2 in Anlage mit dem geraden Arretierabschnitt 11 des Haupthebels 1. Durch die Anlage der beiden geraden Abschnitte aneinander wird ein Verschwenken des Haupthebels 1 in dieser Stellung unmöglich gemacht. Diese Stellung in der sich der Haupthebel 1 in der Aus-Stellung befindet kann durch ein in die Ausnehmung 24 einsteckbares und abschließbares Schlosselement gesichert werden, das ein Zurückschieben des Sicherungshebels 2 unmöglich macht.Due to the design of the operating section 11 and the release section 22, a pivoting of the main lever 1 from the position shown in Figure 1 to the left so in the position shown in Figure 2 is readily possible. The main lever 1 is in the off position shown in Figure 2, the operating portion 12 is no longer in contact with the release portion 22. The safety lever 2 is in this position, although by the in Figure 2 to see latch 3, with the bottom the safety lever 2 cooperates, held lightly, the safety lever 2 but can easily on the handle 25 to the left are pulled up and thus brought into the position shown in Figure 2. Suitably, a stop or the like is provided which determines the final position. In this position, the straight securing portion 21 of the safety lever 2 in abutment with the straight locking portion 11 of the main lever 1. By the abutment of the two straight sections together a pivoting of the main lever 1 is made impossible in this position. This position in which the main lever 1 is in the off position can be secured by an insertable into the recess 24 and lockable lock element, which makes it impossible to push back the safety lever 2.

Soll der Haupthebel 1 in die Ein-Stellung zurückgebracht werden, so muss ggf. das Schlosselement entfernt werden und der Sicherungshebel 2 zurückgeschoben werden, sobald sich der Sicherungshebel 2 in der in Figur 1 gezeigten Stellung befindet, in der sich der Sicherungsabschnitt 21 nicht mehr mit dem Arretierabschnitt 11 in Anlage befindet, kann der Haupthebel 1 in die in Figur 1 gezeigte Stellung zurückgeschwenkt werden. In dieser Stellung ist das Herausziehen des Sicherungshebels 2 nach links oben aufgrund des Eingriffs des Betriebsabschnitts 12 in den Freigabeabschnitt 22 unmöglich.If the main lever 1 is to be returned to the on position, the lock element may have to be removed and the safety lever 2 pushed back as soon as the safety lever 2 is in the position shown in FIG. 1, in which the securing section 21 is no longer with it the locking portion 11 is in abutment, the main lever 1 can be pivoted back into the position shown in Figure 1. In this position, the extraction of the safety lever 2 to the left above due to the engagement of the operating portion 12 in the release portion 22 is impossible.
