Abstract

Switch drives are used for transmitting force from the front of a switching installation to a switching device located in the switching installation. The object here is to simplify the switching operations of a switch drive of the type already mentioned and to provide self-controlling mechanisms which close or open operating openings, indicate unambiguous switch positions and automatically lock the cable connecting spaces, depending on the switching operation. The solution provides that a switching-on spring (6) and a switching-off spring (20) are simultaneously clamped at the maximum force point during manual switching rotation of an operating shaft (1). In this case, mechanical coupling elements (3, 4, 22, 23, 17, 16, 27, 28, 29, 30, 32, 39), > [sic] are moved into the switched-on position, and the switching-off spring is held in the clamped position via a switching-off spring lever (19). A transverse slide (36), which can be operated by the switching shaft (38), makes it possible to lock the operating shafts (1, 80) alternately, is used as the switch position indication, and locks the cable connecting spaces by means of a driver shaft (35) which is connected to the transverse slide and has a locking lever (33). Such a switch drive is suitable for medium-voltage switch devices, especially for load interrupter switches. <IMAGE>

Description

Die Erfindung betrifft einen Schaltantrieb für elektrische Geräte der Mittelspannungstechnik gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a switching drive for electrical devices in medium voltage technology according to the preamble of claim 1.

Ein derartiger Schaltantrieb ist bereits bekannt (DE-A- 32 33 412). Es handelt sich hierbei um einen Federkraftantrieb für einen elektrischen Hochspannungsschalter. Neben einer Einschaltfeder, die eine Schalterwelle und damit die Schaltkontakte des Hochspannungsschalters beim Einschalten antreibt, besitzt der Federkraftantrieb eine Ausschaltfeder, die die Schalterwelle beim Ausschaltvorgang antreibt. Aufgrund dieses Federsystems ist es möglich, eine "AUS"-Schaltung zu speichern. Hierzu sind allerdings mehrere Handdrehbewegungen erforderlich. Sicherheitsrelevante Selbststeuerungen sind bei diesem Federkraftantrieb nicht vorgesehen.Such a switching drive is already known (DE-A-32 33 412). It is a spring-operated actuator for an electrical high-voltage switch. In addition to a closing spring that drives a switch shaft and thus the switch contacts of the high-voltage switch when it is switched on, the spring-loaded drive has a switch-off spring that drives the switch shaft when it is switched off. Due to this spring system it is possible to save an "OFF" circuit. However, this requires several hand movements. Safety-related self-controls are not provided for this spring-loaded drive.

Neue Schaltanlagen-Techniken, insbesondere klein- und kompakt-bauende Anlagen stellen hohe Anforderungen an die hierzu gehörenden Schaltantriebe. Es besteht daher die Forderung, die Antriebstechnik ebenfalls auf kleinstem Raum unterzubringen. Von dieser Technik wird erwartet, daß sie sicherheitsrelevante Bedingungen erfüllt.New switchgear technologies, particularly small and compact systems, place high demands on the associated switch drives. There is therefore a requirement to also accommodate the drive technology in the smallest space. This technique is expected to meet security related requirements.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Schaltantrieb der eingangs geschilderten Art in seinen Schalthandlungen zu vereinfachen, und selbststeuernde Mechanismen vorzusehen, die je nach der Schalthandlung Betätigungsöffnungen verschließen oder freigeben, eindeutige Schaltstellungen anzeigen und automatisch die Kabelanschlußräume verriegeln.The invention is therefore based on the object to simplify a switching drive of the type described in its switching operations, and to provide self-controlling mechanisms that close or release actuation openings depending on the switching operation, display clear switching positions and automatically lock the cable connection spaces.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebene Kombination von Merkmalen gelöst.This object is achieved according to the invention by the combination of features specified in the characterizing part of claim 1.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß die geforderten Funktionen mit einem Minimum an Bauelementen erreicht werden und die Handhabung des Schaltantriebs gegenüber dem Stand der Technik vereinfacht wird.The advantages achieved by the invention are that the required functions are achieved with a minimum of components and the handling of the switching drive is simplified compared to the prior art.

Vorteilhafte Aus- und Weiterbildungen des Gegenstandes nach Anspruch 1 sind den Unteransprüchen zu entnehmen.Advantageous training and further developments of the subject matter according to claim 1 can be found in the subclaims.

Die Schaltsicherheit im Innenraum einer Schaltanlage wird vorteilhafterweise durch eine Schaltschwingsperre erhöht, die verhindert, daß die unvermeidbare Schaltfederschwingung bei einem Schaltvorgang sich auf die in der Schaltanlage befindlichen Schaltmesser überträgt und sich diese durch ein mögliches Durchschwingen sowohl dem Sammelschienen- als auch dem Erdungskontakt soweit nähern, daß eine Wiederzündung oder ein Erdschluß entsteht (Ansprüche 6 und 16).The switching reliability in the interior of a switchgear is advantageously increased by a switch lock, which prevents the inevitable switch spring oscillation from being transmitted to the switch knives located in the switchgear during a switching process, and as close as possible to both the busbar contact and the ground contact due to possible swinging through, that a reignition or an earth fault occurs (claims 6 and 16).

Auch ist es von Vorteil, daß auf die Betätigungswelle eine Steuerhülse mit einem Hebelsystem aufsetzbar ist, um den Schaltantrieb mit einer Hand-Vorlauf-Steuerung betreiben zu können (Ansprüche 13 und 18). Mittels dieser Hand-Vorlauf-Steuerung wird ein Durchschwingen der Schaltmesser des Schaltgeräts verhindert und eine Sofort-"AUS"-Schaltung per Hand erreicht.It is also advantageous that a control sleeve with a lever system can be placed on the actuating shaft in order to be able to operate the switching drive with a manual advance control (claims 13 and 18). This manual advance control prevents the switching blades of the switching device from swinging through and an immediate "OFF" switching is achieved by hand.

Hierzu ist eine auf die Betätigungswelle 1 aufsetzbare Steuerhülse 62 vorgesehen, die wie die Betätigungswelle eine Einstecköffnung 62a und einen Schlitz 62b aufweist.2 shows details of a manual advance control. For this purpose, a control sleeve 62 can be placed on the actuating shaft 1 and , like the actuating shaft , has an insertion opening 62a and a slot 62b .

Diese Steuerhülse 62 besitzt einen Hülsenhebel 63, dessen freies Ende mit einem Mitnahmebolzen 69 versehen ist. Außerdem ist die Steuerhülse 62 mit einem Federhebel 64 für eine Rückholfeder 78 ausgestattet. Ferner ist an der Steuerhülse 62 ein Steuernocken 67 angeformt. Im Abstand unterhalb der Steuerhülse 62 befindet sich eine Steuerwelle 65, deren Achse parallel zu Achse der Steuerhülse 62 verläuft. Die Steuerwelle 65 weist einen Kurvenhebel 66 auf, der mit dem Steuernocken 67 korrespondiert. Ferner ist die Steuerwelle 65 mit einem Gewinderohr 61 versehen, in welches eine einstellbare Anschlagschraube 60 einschraubbar ist. Das Gewinderohr besitzt eine Rückholfeder 68, die für die Anschlagschraube 60 und den Kurvenhebel 66 vorgesehen ist. Die Anschlagschraube 60 stellt sich unter den Schwingsperranschlag 18.This control sleeve 62 has a sleeve lever 63 , the free end of which is provided with a driving pin 69 . In addition, the control sleeve 62 is equipped with a spring lever 64 for a return spring 78 . Furthermore, a control cam 67 is formed on the control sleeve 62 . At a distance below the control sleeve 62 is a control shaft 65 , the axis of which runs parallel to the axis of the control sleeve 62 . The control shaft 65 has a cam lever 66 which corresponds to the control cam 67 .

The threaded tube has a return spring 68 which is provided for the stop screw 60 and the cam lever 66 . The stop screw 60 stands under the rocker stop 18 .

Der Mitnahmebolzen 69 dient der Mitnahme eines Übertragungshebels 70, der mit einer Laufhülse 72 fest verbunden ist. Die Laufhülse 72 wiederum ist auf einer beweglichen Aufnahmeachse 71 aufgesetzt. Für die Winkellage des Übertragungshebels 70 besitzt die Laufhülse 72 Einstellschrauben 73. Fest mit der Aufnahmeachse 71 ist ein weiterer Übertragungshebel 74 verbunden, der über einen Mitnahmebolzen 75 (in Fig. 2 dargestellt) an eine Verbindungsstange 76 angelenkt ist. Diese Verbindungsstange 76 besitzt eine Rückholfeder 77. Eine Schaltwippe 81 ist als zweiarmiger Hebel ausgebildet und fest mit einer Laufbuchse 79 verbunden, die auf eine Betätigungswelle 80 für einen Erdungsschalter aufgeschoben ist.

A rocker switch 81 is designed as a two-armed lever and is fixedly connected to a bushing 79 , which is pushed onto an actuating shaft 80 for an earthing switch. The rocker switch 81 is designed as a two-armed lever, with one end carrying a release pin 82 which presses the switch-off control lever 21 (shown in FIG. 1) and the other end is connected to the connecting rod 76 via a drive pin 83 .

Fig. 3 und 4 verdeutlichen nochmals Einzelheiten der Hand-Vorlauf-Steuerung. Die Bezugszeichen sind die gleichen wie in Fig. 1 und 2.3 and 4 again illustrate details of the manual flow control. The reference numerals are the same as in Figs. 1 and 2.

Die Funktionsweise des Schaltantriebs ist folgende:The switching drive works as follows:

Ein Betätigungshebel (nicht dargestellt) wird in die vordere Mitnahmekontur der Betätigungsswelle 1 gesteckt. Durch eine Rechtsdrehung wird die Einschaltfeder 6 über den Schaltfederhebel 3 und den Federaufhängebolzen 4 in die Totpunktstellung bewegt. Dabei legt sich die Nadelrolle 23 vor das Mitnahmesegment 17 und bewegt die hiermit verbundenen Teile, wie die Laufbuchse 16, den Schwingsperranschlag 18 und den Ausschaltfederhebel 19, wie auch den Ausschaltsteuerhebel 21, den Nadelrollenhebel 22, die Nadelrolle 23, den Einstellbolzen 24 mit der Einstellschraube 25 und die Verbindungsbuchse 26, dem Mitnahmehebel 27 und die Mitnahmestange 29 gleichfalls in eine Rechtsdrehung. Dabei wird die Ausschaltfeder 20 über einen Bolzen im vorderen Teil des U-förmigen Traggestells 45 aufgehängt und in ihrer Schaltkraft gespannt. Diese Kraft stützt sich über das Mitnahmesegment 17 und die Nadelrolle 23, verbunden mit dem Federaufhängebolzen 4 und dem Schaltfederhebel 3, ab. Bei einer weiteren Handdrehung nach rechts schießt dann die Einschaltfeder 6 über den Totpunkt, wobei der Leerlauf im kastenförmigen Mitnahmeschieber 30 bis zur Kraftschlüssigkeit desselben mit der Mitnahmeachse 35 aufgehoben wird, welche ohne Spiel im Schaltwellenhebel 32 steckt. Der Schaltwellenhebel 32 ist wiederum über die Klemmbuchse 39 kraftschlüssig mit der Schaltwelle 38 verbunden und wird in eine schlagartige Linksdrehung für den inneren Schaltvorgang versetzt. Mit diesem Sprung der Einschaltfeder 6 wird die Ausschaltfeder 20 in ihrer vollen Kraft auf ihrer Position gehalten. Mit dieser Schalthandlung ist beispielsweise das innere Schaltgerät "EIN"- geschaltet, die Ausschaltfeder 20 über dem Ausschaltfederhebel 19 mit der Laufbuchse 16, dem Mitnahmesegment 17, dem Ausschaltsteuerhebel 21, dem Nadelrollenhebel 22, der Nadelrolle 23 verbunden. Die Ausschaltfeder 20 ist dabei voll gespannt und "AUS"-schaltbereit.An operating lever (not shown) is in the front driving contour the actuating shaft 1 inserted. By a clockwise rotation, the closing spring 6 is moved via the switching spring lever 3 and the Federaufhängebolzen 4 in the dead center position. The needle roller 23 lies in front of the driving segment 17 and moves the parts connected to it, such as the bushing 16 , the rocker stop 18 and the switch-off spring lever 19 , as well as the switch-off control lever 21 , the needle roller lever 22 , the needle roller 23 , the adjusting bolt 24 with the adjusting screw 25 and the connecting bush 26 , the driving lever 27 and the driving rod 29 also in a right turn. The opening spring 20 is suspended by a bolt in the front part of the U-shaped support frame 45 and tensioned in its switching force. This force is supported by the driving segment 17 and the needle roller 23 , connected to the spring suspension pin 4 and the switching spring lever 3 . With a further turn of the hand to the right, the closing spring 6 then shoots past the dead center, the idling in the box-shaped driving slide 30 being canceled to the point of non-positive engagement with the driving axis 35 , which is inserted in the switching shaft lever 32 without play. The selector shaft lever 32 is in turn non-positively connected to the selector shaft 38 via the clamping bush 39 and is set in an abrupt left turn for the internal switching operation. With this jump of the switch-on spring 6 , the switch-off spring 20 is held in its full force in its position. With this switching action, for example, the inner switching device is "ON" - the switch-off spring 20 is connected via the switch-off spring lever 19 to the bushing 16 , the driving segment 17 , the switch-off control lever 21 , the needle roller lever 22 , the needle roller 23 . The switch-off spring 20 is fully tensioned and "OFF" ready for switching.

Gleichzeitig wird durch die rechtsdrehende "EIN"-Schaltbewegung über die Aufzugsrolle 49 der Kurvenhebel 12 gemeinsam mit dem Rollenhebel 13 die Feder 51 für den Ausgelöstspeicher, verbunden mit dem vollständigen Rollenhebel 13 der Auslöserolle 14 gespannt, wobei die vordere Kontur des Rollenhebels 13 sich sperrend gegen die Halbwellenkontur der Auslösewelle 46 legt.At the same time, the clockwise rotating "ON" switching movement via the elevator roller 49 of the cam lever 12 together with the roller lever 13, the spring 51 for the tripped memory, connected to the complete roller lever 13 of the trigger roller 14 , the front contour of the roller lever 13 locking against one another the half-wave contour of the trigger shaft 46 sets.

Bei einem mechanischen Kurzimpuls (Sicherung) oder elektrischen Kurzimpuls (Arbeitsstromauslöser, Unterspannungsauslöser) wird die Auslösewelle 46 in eine Linksdrehung über den Auslösehebel 47 und die Auslöse-Impuls-Stange 48 versetzt. Die Halbwellenkontur der Auslösewelle 46 gibt die Kontur des Rollenhebels 13 im unteren Bereich frei, so daß die Auslöserolle 14 über die Spannkraft der Feder 51 gegen die Bogenkontur des Ausschaltsteuerhebels 21 geschlagen wird, und so die Nadelrolle 23 unter dem Mitnahmesegment 17 heraustreibt und damit die gespannt gehaltene Ausschaltfeder 20 mit dem verbundenen Mitnahmehebel 27, der Mitnahmestange 29 und den nachfolgenden Bauteilen freigibt. Damit erfolgt eine schlagartige Drehung der Schaltwelle 38 in entgegengesetzter Richtung zu einer "AUS"-Schaltung des inneren Schaltgeräts.With a mechanical short pulse (fuse) or electrical Short pulse (shunt release, undervoltage release), the trigger shaft 46 is turned to the left via the trigger lever 47 and the trigger pulse rod 48 . The half-wave contour of the trigger shaft 46 releases the contour of the roller lever 13 in the lower region, so that the trigger roller 14 is struck against the arc contour of the switch-off control lever 21 by the tension force of the spring 51 , and thus drives out the needle roller 23 under the driving segment 17 and thus the tensioned held switch-off spring 20 with the connected driving lever 27 , the driving rod 29 and the subsequent components releases. This results in a sudden rotation of the switching shaft 38 in the opposite direction to an "OFF" switching of the inner switching device.

Soll ein nochmaliges Einschalten erfolgen, muß durch eine Handlinksdrehung der Betätigungswelle 1 die Nadelrolle 23 wieder unter das Mitnahmesegment 17 gestellt werden, wobei dann die "EIN"-Schaltung wieder durch eine Rechtsdrehung der Betätigungswelle 1 erfolgt.Is to be followed by a second power-up, the needle roller 23 to be put back under the driving segment 17 by a manual clockwise rotation of the actuating shaft 1, and then the "ON" circuit takes place again by a clockwise rotation of the actuating shaft. 1

Steht nach wie vor ein "AUS"-Impuls durch eine Fernwarte oder Sicherung an der Auslösewelle 46 an, so kann der Rollenhebel 13 an der Halbwellenkontur an der Auslösewelle 46 nicht gehalten werden. Die Kraft der Feder 51 drückt statisch über die gesamte Kurve des Ausschaltsteuerhebels 21 die Nadelrolle 23 unter dem Mitnahmesegment 17 heraus, sodaß auch bei einer weiteren Übertotpunktdrehung der Einschaltfeder 6 eine kraftschlüssige Mitnahme des Mitnahmesegments 17 nicht erfolgen kann. Man spricht in diesem Fall von einer Fehlschaltung. Erst wenn der Fehler im Netzbetrieb beseitigt ist und der "AUS"-Impuls aufgehoben ist, kann eine "EIN"-Schaltung erfolgen. Für die Nadelrolle 23 wird ihre Selbsthaltekraft über den Einstellbolzen 24 und die Einstellschraube 25 eingestellt.If there is still an "OFF" pulse from remote maintenance or security on the trigger shaft 46 , the roller lever 13 cannot be held on the half-wave contour on the trigger shaft 46. The force of the spring 51 statically presses the needle roller 23 out from under the driving segment 17 over the entire curve of the switch-off control lever 21 , so that even if the closing spring 6 rotates beyond dead center, the driving segment 17 cannot be positively driven. In this case one speaks of an incorrect switching. An "ON" switch can only take place when the fault in mains operation has been eliminated and the "OFF" pulse has been removed. For the needle roller 23 , its self-holding force is set via the adjusting bolt 24 and the adjusting screw 25 .

Für die normalen "EIN" und "AUS"-Schaltungen wird, ohne das ein Ausschalt-Impuls anliegt, einfach durch Handdrehung der Betätigungswelle 1 nach rechts ("EIN") oder nach links ("AUS") die Einschaltfeder 6 jeweils über den Totpunkt bewegt, womit ein Drehsprung erfolgt, welcher über die gekoppelten Bauteile die Schaltwelle 38 in die gewünschte Schaltdrehung versetzt.For the normal "ON" and "OFF" circuits, without a switch-off pulse being applied, simply turn the actuating shaft 1 to the right ("ON") or to the left ("OFF") to turn the closing spring 6 over the dead center moves, which results in a rotary jump, which the switching shaft via the coupled components 38 set in the desired shift rotation.

Aus Sicherheitgründen müssen Verriegelungen und Anzeigen grundsätzlich von der Schaltwelle 38, die kraftschlüssig mit den inneren Schaltmessern des Schaltgeräts verbunden sind, gesteuert werden. Dies erfolgt über die Schaltwelle 38, die Klemmbuchse 39, die Klemmschraube 40, den Schaltwellenhebel 32 und die Mitnahmeachse 35 nach der Schalterstellungsanzeige 36, die gleichzeitig die Verriegelung für den Erderantrieb durch die Schlitze 85 in den Betätigungswellen 1 und 80 im vorderen Bereich, bei Betätigung des Schaltgeräts nach "EIN" die gleiche, in Fig. 1 nicht dargestellte Betätigungswelle 80 für den Erder-Antrieb mit dem Durchfahren in den Schlitz 85 der Betätigungswelle 80 für den Erder, diese verschließt, sodaß eine Handbetätigung nicht möglich ist. Derselbe Vorgang erfolgt umgekehrt bei "EIN"-Schaltung des Erders. In gleicher sicherer Weise erfolgt die Ausgelöst-Anzeige über den Ausgelöst- Anzeiger 15. Ebenso wird der Verriegelungshebel 33 kraftschlüssig von der Schaltwelle 38 betätigt, und ein innerer Verschluß im Kabelanschlußraum erreicht, der ein Abnehmen der Kabelraumverschlußklappe (nicht gargestellt) nur dann ermöglicht, wenn das Schaltgerät "AUS" und der Erdungsschalter "EIN" geschaltet sind.For safety reasons, interlocks and displays must always be controlled by the control shaft 38 , which are non-positively connected to the internal switching blades of the switching device. This takes place via the selector shaft 38 , the clamping bush 39 , the clamping screw 40 , the selector shaft lever 32 and the driving axis 35 according to the switch position indicator 36 , which simultaneously locks the earth drive through the slots 85 in the actuating shafts 1 and 80 in the front area when actuated of the switching device after "ON" the same, not shown in Fig. 1, the actuating shaft 80 for the earthing drive with the passage into the slot 85 of the actuating shaft 80 for the earthing, closes it, so that manual operation is not possible. The same process takes place in reverse when the earth switch is "ON". In the same safe manner, the triggered display is made via the triggered indicator 15 . Likewise, the locking lever 33 is non-positively actuated by the switching shaft 38 , and an inner closure is reached in the cable connection space, which allows the cable space closure flap to be removed (not shown) only when the switching device "OFF" and the earthing switch "ON" are switched on.

Bei Betriebssystemen über 10 kV ist es aus Schaltsicherheitsgründen erforderlich, ein Durchschwingen der Schaltmesser, bedingt durch die Eigenschwingungen der Einschaltfeder 6 und der Ausschaltfeder 20 zu verhindern. Weiterhin wird die Forderung gestellt, daß eine "AUS"-Schaltung ebenfalls durch einen kurzen Handbetätigungs-Impuls erfolgen kann, ohne die Betätigungswelle 1 in eine Drehung zu versetzen. Beide Forderungen werden erfindungsgemäß durch die "Hand-Vorlauf-Steuerung" erreicht.In operating systems above 10 kV, it is necessary for switching safety reasons to prevent the switching blades from swinging due to the natural oscillations of the closing spring 6 and the closing spring 20 . Furthermore, there is the requirement that an "OFF" switching can also be carried out by a short manual actuation pulse without causing the actuating shaft 1 to rotate. According to the invention, both requirements are met by the "manual advance control".

Die Teile dieses Systems werden entsprechend der Fig. 3 auf die Betätigungswellen 1 und 80 aufgesetzt, wobei die Anschlagschraube 60 unterhalb des Schwingsperranschlages mit 1,5 mm Spiel gestellt wird. Bei einer sofortigen Handauslösung durch den Handhebel nach links wird die Steuerhülse 62 mit dem Hülsenhebel 63, dem Federhebel 64 und dem Steuernocken 67 nach links ("AUS"-Schaltdrehung) bewegt (Leerlauf), ohne daß schon eine Mitnahme der Betätigungswelle 1 erfolgt. Der Kurvenhebel 66 verbunden mit der Steuerwelle 65, dem Gewinderohr 61 und der Anschlagschraube 60 bleibt in seiner unterstellten Sperrfunktion. Die Übertragungshebel 70 und 74 sowie die Verbindungsstange werden so bewegt, daß die Schaltwippe 81 drehend auf der Betätigungswelle 80 mit ihrem Auslösebolzen 82 statisch drückend auf die Kontur des Ausschaltsteuerhebels 21 derart wirkt, daß die Nadelrolle 23 unter dem Mitnahmesegment 17 herausgetrieben wird. Es erfolgt eine sofortige "AUS"-Schaltung des Schaltantriebs. In dieser "AUS"-geschaltet-Stellung fällt die Schwingsperre mit der Steuerwelle 65, dem Gewinderohr 61 und der Anschlagschraube 60 unter dem Schwingsperranschlag 18 und arretiert die Laufbuchse 16, das Mitnahmesegment 17, den Mitnahmehebel 27, die Mitnahmestange 29, den kastenförmigen Mitnahmeschieber 30 und die Mitnahmeachse 35 derart, daß bei einer "EIN"-Schaltung des Erderantriebs mit seiner Einschaltfeder 6 die entspannte Ausschaltfeder 20 nicht schwingen kann. Es handelt sich hierbei um eine mögliche Bewegung des Schaltwellenhebels 32, der Schaltwelle 38 und der Klemmbuchse 39 mit den im Innenraum der Schaltanlage befindlichen gekoppelten Schaltmesser des Schaltgeräts.The parts of this system are placed according to FIG. 3 on the actuating shafts 1 and 80 , the stop screw 60 being placed below the rocker stop with 1.5 mm play. In the event of an immediate manual triggering by the hand lever to the left, the control sleeve 62 with the sleeve lever 63 , the spring lever 64 and the control cam 67 to the left ("OFF" switching rotation) moves (idle) without the actuator shaft 1 already being taken along. The cam lever 66 connected to the control shaft 65 , the threaded tube 61 and the stop screw 60 remains in its assumed locking function. The transmission lever 70 and 74 and the connecting rod are moved so that the rocker switch 81 rotates on the actuating shaft 80 with its release bolt 82 statically pressing on the contour of the opening control lever 21 such that the needle roller 23 is driven out under the driving segment 17 . There is an immediate "OFF" switching of the switching drive. In this "OFF" switched position, the vibration lock with the control shaft 65 , the threaded tube 61 and the stop screw 60 falls under the vibration lock stop 18 and locks the bushing 16 , the driving segment 17 , the driving lever 27 , the driving rod 29 , the box-shaped driving slide 30 and the driving axis 35 such that when the earth drive is switched "ON" with its closing spring 6, the relaxed opening spring 20 cannot oscillate. This is a possible movement of the selector shaft lever 32 , the selector shaft 38 and the clamping bush 39 with the coupled switching blades of the switching device located in the interior of the switchgear.

Die Schwingsperre wirkt in gleicher Weise beim "AUS"-schalten des Erderantriebes. Nach dieser "AUS"-Schaltung kann das Schaltgerät wieder "EIN"-geschaltet werden. Bei diesem Schaltvorgang wird vorab die Steuerhülse 62 mit ihren Bauteilen nach rechts gedreht, wobei der Steuernocken 67 den Kurvenhebel 66 mit der Steuerwelle 65, dem Gewinderohr 61 und der Anschlagschraube 60 nach rechts bewegt und den Schwingsperranschlag 18 vorab der Drehung der Antriebswelle 1 freigibt. Die "EIN"-Schaltung des Schaltantriebes kann erfolgen.The vibration lock acts in the same way when the earth drive is switched "OFF". After this "OFF" switching, the switching device can be switched "ON" again. In this switching operation, the control sleeve 62 is rotated with its components to the right beforehand, the control cam 67 moving the cam lever 66 with the control shaft 65 , the threaded tube 61 and the stop screw 60 to the right and releasing the rocker stop 18 in advance of the rotation of the drive shaft 1 . The switching drive can be switched "ON".
