Definitions
- the invention relates to a lockable locking handle system for an electrical switching device.
- Various regulations such as IEC 60947-1 and DIN EN 60204-1, require that, in certain installation situations, electrical switchgear can be secured against being switched back on with one or more U-locks in the OFF position of the switching device, in order, for example, to switch it on again. to prevent the electrical system from being switched on while maintenance work is being carried out on the system.
- a pluggable on a switching shaft of a rotary switch and fastened to the rotary switch or a front panel device from the front forth base plate includes a rotatably on the switching shaft plug-lock disk with at least one recess, a laterally displaceable for engaging in the recess of the locking disc, strip-shaped latch and one to the latch vertically formed, extending parallel to the lower edge of the base plate slide.
- the slide protrudes laterally with one end over the base plate and is acted upon at the other end by a compression spring.
- a lid which can be placed on the base plate covers the base plate together with the slider.
- the slide and the part surrounding the slide of the lid are provided with holes corresponding to the slide pushed, in which at least a curtain or padlock for locking the rotary switch can be plugged.
- the lid In this locked state, the lid can not be removed, so that a release of the lock is not possible.
- a disadvantage is the unsatisfactory by the twist grip closure device unsatisfactory size and the number of components.
- a lockable locking handle system which forms a positive connection with a switching shaft of a switching device in the direction of rotation and form-fit or non-positively snapped onto the shift shaft in the axial direction, and has a locking device as a pivot lever which in the pivoted position, both the rotational movement of the Turning handle as well as the removal of the shift shaft locks.
- a locking device as a pivot lever which in the pivoted position, both the rotational movement of the Turning handle as well as the removal of the shift shaft locks.
- Holes of the pivot lever closing or sealing devices can be used as protection against unauthorized operation.
- the disadvantage of this solution is that the switching shaft end must be tuned very precisely to the nose of the pivot lever, which is not to realize at different distances of the switch from the front panel or at different front panel thicknesses.
- a lockable actuator with a rotary handle known which is fixed by means of a locking pin on the switching shaft of a rotary switch.
- a locking lever is pivotally mounted in a bearing block, which is held in a recess of the rotary handle and in which a frictionally coupled to the locking lever coupled and engaging in a corresponding recess of the rotary switch housing locking pin is mounted axially movable.
- the locking lever is movable in an away from the rotary switch open groove of the rotary handle and provided with a slot for receiving U-locks. In the rest position, the locking lever has a low over the side surface of the rotary handle attack surface.
- a transverse pin connects the locking pin via a slot with the locking lever.
- DE 43 21 981 C2 is a lockable actuator for a rotary switch known with a cover which is locked on the front of the rotary switch and extends through the switching shaft, with a rotatably mounted on the selector shaft and sitting in front of the cover rotary handle with a locking opening for a hook-lock and with a vertical slidably mounted to the switching shaft axis in the rotary handle, operable from the outside locking slide to block or release the closing opening.
- the cover is held together with the rotary handle and the locking slide by a locking ring to an attachable to the rotary switch assembly.
- the locking slide provided with an actuating extension is substantially rectangular and has on its side facing the rotary switch on a groove which comes in the locked position of the rotary handle out of coverage with a guide collar of the cover, but what is located next to the groove paragraph blocking against a gap of the guide collar sets.
- the disadvantage of this solution is that it is fixed unchanged with respect to the positions of its lockable switching position and does not allow additional Absch spapositionen.
- a lockable actuating device for a turntable in which a blocking pin is actuated by a locking device serving as a locking device, which in turn occurs with a non-rotatable locking disc in blocking action.
- the non-positively clamped on the shift shaft rotary handle combines in itself the locking pin.
- the company Eaton Industries offers in its catalog HPL 2010 a rotary handle with locking ring SVB, whereby the rotary handle can be secured over the locking ring with up to three padlocks against unauthorized switching.
- a fourth hole in the twist grip and wreath is conceivable, but then also a lockability would be given in positions that are normatively inadmissible. For example, in the case of contacts welded in the ON position, the handle could be turned so far in the direction of OFF that a lock could be suspended and the impression of a safe OFF position would be created.
- the lockable locking handle system is characterized in that it has a blocking handle pushed onto the switching shaft of the electrical switching device and divided into the two components of the rotary handle and locking collar.
- the locking collar relative to the rotary handle in the direction of the shift shaft longitudinal axis is vertically displaceable in a COMPLETED and an OPEN position, wherein the locking collar is so engaged with the ratchet that he is not rotated in the closed position relative to the ratchet.
- Electrical switching devices are characterized in that they have an inventive lockable locking handle system with the feature combinations according to claims 1 to 8.
- the locking ring has an at least guide groove on its inner peripheral surface.
- the locking collar has at least one corresponding guide rail on its outer peripheral surface.
- the guide groove is configured so that the ratchet can only be moved vertically in the direction of the longitudinal axis of the shift shaft in a COMPLETED position when the shift shaft is in the OFF position. In this COMPLETED position, the ratchet and thus the locking handle is rotatably connected to the ratchet so that it does not turn in this position, the switching shaft and thus can not turn on the switch.
- the locking collar has at least one opening in its peripheral side, through which the bow of a padlock can be guided when the locking collar is in the closed position.
- the locking collar can not be transferred to the open position without removing the bracket of the castle.
- the bracket can be performed by at least 4 U-locks by the at least one breakthrough in the peripheral side of the locking collar.
- the lockable locking handle system has at least two guide grooves and guide rails over the circumference of the locking collar and the locking collar. As a result, the locking ring can be guided symmetrically.
- the advantage of the invention lies in the fact that the prevention of the rotational movement of the locking handle and thus the prevention of the switching of the electrical switching device is functionally separated in the locking handle according to the invention of the lockability.
- the prevention of the rotational movement takes place via the engagement of the guide rail of the locking collar in the guide groove of the locking ring.
- the lockability takes place by preventing vertical movement of the locking ring out of the COMPLETED position. In this case, it can be prevented by a suitable dimensioning of the fit between the guide rail and guide groove, that the locking handle can be rotated in the COMPLETED position so far that the switch is no longer in a safe OFF state or that at e.g.
- the locking handle can be rotated to a position that without the contacts would be welded would correspond to a safe OFF state of the electrical switching device.
- the COMPLETED position of the lockable locking handle in the axial direction pulled out of the locking collar locking collar partially covers the tangible side surface of the rotary handle, so that an operator in this COMPLETED position of the rotary handle less attack surface for the hand or find a tool as in the OPEN position.
- less torque can be applied to the rotary handle in this position than in the OPEN position.
- an unauthorized switching on the electrical switching device is difficult when the handle is closed by violence.
- Lockable locking handle system (100) is made in one piece.
- the lockability is provided by breakthrough pairs in the peripheral sides of the locking ring (130) and the locking handle.
- the locking handle (100) is in a position corresponding to the OFF position of the electrical switching device, so are the openings (115) of the breaker pairs in the peripheral sides of the locking ring (130) and locking handle (100) in coverage, so that the Strap of a U-lock through both openings (115, 125) of a breakthrough pair can be passed through.
- a breakthrough pairing must be available for each earlock provided, wherein the dimensions of the openings (115, 125) must be matched to the diameter of the lock bracket.
- the rotary handle (110) can possibly be rotated so far that a secure separation distance between the switching contacts of the electrical switching device is no longer present. Also, the case is conceivable that the switching contacts of the electrical switching device are welded together. In this case, the rotary handle (100) with locking collar (120) must not turn so far that the openings (115, 125) of the breakthrough pairings so far come to cover that a padlock can be mounted. Since the scope of the locking handle (100) or locking ring (130) is limited depending on the size of the switch, the number of openings (115, 125) is also limited, should the above conditions are met.
- Fig. 2 shows the components locking collar (120) and rotary handle (110) of a lockable locking handle system according to the invention.
- breakthroughs (115, 125) for the Ironing of padlocks It can be seen that these openings (115, 125) in the circumferential direction need not be matched to the diameter of the lock bracket so that only a very limited clearance between the lock bracket and breakthrough (115, 125) should be allowed.
- Fig. 2 Long holes as breakthrough (115, 125) to recognize.
- the brackets of the U-locks need only prevent the vertical movement of the locking collar (120) relative to the locking ring (130) (see also the following figures).
- guide rail (126) on the locking collar (120) which cooperates with the guide groove (136) of the locking ring (see also the following figures).
- Fig. 3 shows a locking ring (130) according to the invention with the guide groove (136).
- This guide groove (136) consists of a first part (137) with a main extent in the circumferential direction and a second part (138) with a main extension direction substantially perpendicular to the circumferential direction.
- the first part (137) of the guide groove (136) extends in the circumferential direction at least over a part of the inner peripheral surface of the locking ring (130).
- the second part (138) of the guide groove (136) is located at one end of the first part (137) of the guide groove (136) at the location of the circumference corresponding to the position of the guide rail (126) on the locking collar (120) the electrical switching device is in the OFF state.
- Fig. 4 shows the inventive components rotary handle (110), locking collar (120) and locking ring (130) mounted in the OPEN position in side view and section.

Die Firma Eaton Industries bietet in Ihrem Katalog HPL 2010 einen Drehgriff mit Sperrkranz SVB an, wobei der Drehgriff über den Sperrkranz mit bis zu drei Vorhängeschlössern gegen unbefugtes Einschalten gesichert werden kann. Um die Forderung nach einem vierten Schloss zu erfüllen, ist ein viertes Loch in Drehgriff und Kranz denkbar, jedoch wäre dann auch eine Abschließbarkeit in Positionen gegeben, die normativ unzulässig sind. Beispielsweise könnte bei in EIN-Stellung verschweißten Kontakten im Grundgerät der Griff so weit in Richtung AUS gedreht werden, dass ein Schloss eingehängt werden könnte und der Eindruck einer sicheren AUS-Stellung erweckt würde.The company Eaton Industries offers in its catalog HPL 2010 a rotary handle with locking ring SVB, whereby the rotary handle can be secured over the locking ring with up to three padlocks against unauthorized switching. In order to meet the requirement for a fourth lock, a fourth hole in the twist grip and wreath is conceivable, but then also a lockability would be given in positions that are normatively inadmissible. For example, in the case of contacts welded in the ON position, the handle could be turned so far in the direction of OFF that a lock could be suspended and the impression of a safe OFF position would be created.
Es ist daher Aufgabe der vorliegenden Erfindung, ein verriegelungsfähiges Sperrgriffsystem für ein elektrisches Schaltgerät bereitzustellen, das in einer sicheren AUS-Stellung des Schaltgeräts mit mindestens vier Vorhänge- oder Bügelschlössern gegen unbefugtes Einschalten gesichert werden kann.It is therefore an object of the present invention to provide a lockable locking handle system for an electrical switching device that can be secured in a safe OFF position of the switching device with at least four curtain or U-locks against unauthorized switching.
Ausgehend von einem verriegelungsfähigen Sperrgriffsystem der eingangs genannten Art wird die Aufgabe erfindungsgemäß durch die Gesamtheit der Merkmale des Hauptanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen 2 bis 8 zu entnehmen.Starting from a lockable locking handle system of the type mentioned, the object is achieved by the totality of the features of the main claim 1. Further advantageous embodiments of the invention are described in the dependent claims 2 to 8.
Das erfindungsgemäße verriegelungsfähiges Sperrgriffsystem zeichnet sich dadurch aus, dass er einen auf die Schaltwelle des elektrischen Schaltgerätes geschobenen und in die zwei Komponenten Drehgriff und Sperrkragen aufteilten Sperrgriff aufweist. Dabei ist der Sperrkragen gegenüber dem Drehgriff in Richtung der Schaltwellenlängsachse vertikal in eine ABGESCHLOSSEN- und eine OFFEN-Position verschiebbar, wobei der Sperrkragen sich so mit dem Sperrkranz im Eingriff befindet, dass er in der Abgeschlossen-Position nicht gegenüber dem Sperrkranz verdrehbar ist.The lockable locking handle system according to the invention is characterized in that it has a blocking handle pushed onto the switching shaft of the electrical switching device and divided into the two components of the rotary handle and locking collar. In this case, the locking collar relative to the rotary handle in the direction of the shift shaft longitudinal axis is vertically displaceable in a COMPLETED and an OPEN position, wherein the locking collar is so engaged with the ratchet that he is not rotated in the closed position relative to the ratchet.
Es ist eine weitere Aufgabe der vorliegenden Erfindung, ein elektrisches Schaltgerät anzugeben, das sich in einer sicheren AUS-Stellung mit mindestens vier Vorhänge- oder Bügelschlössern gegen unbefugtes Einschalten gesichert werden kann.It is a further object of the present invention to provide an electrical switching device that can be secured against unauthorized start-up in a safe OFF position with at least four curtain or padlocks.
Diese weitere, der Erfindung zugrunde liegende Aufgabe wir durch die Merkmalskombination des Anspruchs 9 gelöst.This further object of the invention is achieved by the feature combination of claim 9.
Erfindungsgemäße elektrische Schaltgeräte zeichnen sich dadurch aus, dass sie ein erfindungsgemäßes verriegelungsfähiges Sperrgriffsystem mit den Merkmalskombinationen gemäß den Ansprüchen 1 bis 8 aufweisen.Electrical switching devices according to the invention are characterized in that they have an inventive lockable locking handle system with the feature combinations according to claims 1 to 8.
Erfindungsgemäß weist der Sperrkranz eine mindestens Führungsnut auf seiner inneren Umfangsfläch auf. Der Sperrkragen hingegen weist auf seiner äußeren Umfangsfläche mindestens eine korrespondierende Führungsschiene auf. Die Führungsnut ist so ausgestaltet, dass der Sperrkranz nur dann vertikal in Richtung der Längsachse der Schaltwelle in eine ABGESCHLOSSEN-Position verschoben werden kann, wenn sich die Schaltwelle in der AUS-Position befindet. In dieser ABGESCHLOSSEN- Position ist der Sperrkranz und damit der Sperrgriff drehfest mit dem Sperrkranz verbunden, so dass er in dieser Position die Schaltwelle nicht verdrehen und damit den Schalter nicht einschalten kann.According to the invention the locking ring has an at least guide groove on its inner peripheral surface. The locking collar, however, has at least one corresponding guide rail on its outer peripheral surface. The guide groove is configured so that the ratchet can only be moved vertically in the direction of the longitudinal axis of the shift shaft in a COMPLETED position when the shift shaft is in the OFF position. In this COMPLETED position, the ratchet and thus the locking handle is rotatably connected to the ratchet so that it does not turn in this position, the switching shaft and thus can not turn on the switch.
Erfindungsgemäß weist der Sperrkragen mindestens einen Durchbruch in seiner Umfangsseite auf, durch den der Bügel eines Bügelschlosses geführt werden kann, wenn sich der Sperrkragen in der ABGESCHLOSSEN-Position befindet. Somit kann der Sperrkragen nicht in die Offen-Position überführt werden kann, ohne den Bügel des Schlosses zu entfernen.According to the invention, the locking collar has at least one opening in its peripheral side, through which the bow of a padlock can be guided when the locking collar is in the closed position. Thus, the locking collar can not be transferred to the open position without removing the bracket of the castle.
In einer bevorzugten Ausführungsform können durch den mindestens einen Durchbruch in der Umfangsseite des Sperrkragens die Bügel von mindestens 4 Bügelschlössern geführt werden.In a preferred embodiment, the bracket can be performed by at least 4 U-locks by the at least one breakthrough in the peripheral side of the locking collar.
In einer vorteilhaften Ausführungsform weist das verriegelungsfähige Sperrgriffsystem mindestens zwei Führungsnuten und Führungsschienen über den Umfang des Sperrkranzes und des Sperrkragens auf. Dadurch kann der Sperrkranz symmetrisch geführt werden.In an advantageous embodiment, the lockable locking handle system has at least two guide grooves and guide rails over the circumference of the locking collar and the locking collar. As a result, the locking ring can be guided symmetrically.
Der Vorteil der Erfindung liegt darin begründet, dass die Verhinderung der Drehbewegung des Sperrgriffs und damit die Verhinderung der Einschaltung des elektrischen Schaltgerätes bei dem erfindungsgemäßen Sperrgriff von der Abschließbarkeit funktionell getrennt ist. Die Verhinderung der Drehbewegung erfolgt über den Eingriff der Führungsschiene des Sperrkragens in die Führungsnut des Sperrkranzes. Die Abschließbarkeit hingegen erfolgt durch eine Verhinderung einer Vertikalbewegung des Sperrkranzes aus der ABGESCHLOSSEN-Position heraus. Dabei kann durch eine geeignete Dimensionierung der Passung zwischen Führungsschiene und Führungsnut verhindert werden, dass der Sperrgriff in der ABGESCHLOSSEN-Position soweit gedreht werden kann, dass sich der Schalter nicht mehr in einem sicheren AUS-Zustand befindet bzw. dass sich bei z.B. verschweißten Schaltkontakten des elektrischen Schaltgerätes der Sperrgriff in eine Position gedreht werden kann, die ohne dass die Kontakte verschweißt wären einem sicheren AUS-Zustand des elektrischen Schaltgerätes entsprechen würde. Als weiterer Vorteil ist zu sehen, dass der in der ABGESCHLOSSEN-Position des verriegelungsfähigen Sperrgriffs in axialer Richtung aus dem Sperrkranz herausgezogenen Sperrkragen die greifbaren Seitenfläche des Drehgriffs teilweise verdeckt, so dass ein Bediener in dieser ABGESCHLOSSEN-Position des Drehgriffs weniger Angriffsfläche für die Hand oder ein Werkzeug vorfindet als in der OFFEN-Position. Dadurch kann in dieser Position weniger Drehmoment auf den Drehgriff aufgebracht werden als in der OFFEN-Position. Dadurch wird ein unbefugtes Einschalten des elektrischen Schaltgerätes bei abgeschlossenem Drehgriff durch Gewaltanwendung erschwert.The advantage of the invention lies in the fact that the prevention of the rotational movement of the locking handle and thus the prevention of the switching of the electrical switching device is functionally separated in the locking handle according to the invention of the lockability. The prevention of the rotational movement takes place via the engagement of the guide rail of the locking collar in the guide groove of the locking ring. The lockability, however, takes place by preventing vertical movement of the locking ring out of the COMPLETED position. In this case, it can be prevented by a suitable dimensioning of the fit between the guide rail and guide groove, that the locking handle can be rotated in the COMPLETED position so far that the switch is no longer in a safe OFF state or that at e.g. welded switch contacts of the electrical switching device, the locking handle can be rotated to a position that without the contacts would be welded would correspond to a safe OFF state of the electrical switching device. As a further advantage, it can be seen that in the COMPLETED position of the lockable locking handle in the axial direction pulled out of the locking collar locking collar partially covers the tangible side surface of the rotary handle, so that an operator in this COMPLETED position of the rotary handle less attack surface for the hand or find a tool as in the OPEN position. As a result, less torque can be applied to the rotary handle in this position than in the OPEN position. As a result, an unauthorized switching on the electrical switching device is difficult when the handle is closed by violence.
