Abstract

An electromagnetic switching apparatus having a switch position indicator is disclosed. The switch position indicator is in functional connection with the contact carrier and protrudes beyond the cover of the switching apparatus in at least one switch position. The switch position indicator is coupled to the contact carrier by apparatus such that the switch position indicator travels a greater distance than the movable contact carrier in going from at least one switch position to another. Thereby, an unequivocal switch position indication can be obtained, particularly in an open contact condition which satisfies switch disconnect function conditions, thereby making the switching apparatus useful as a disconnect switch.

Description

Die Erfindung bezieht sich auf ein elektromagnetisches Schaltgerät mit einem vom Kontaktbrückenträger unmittelbar betätigten, die Kontur des Schaltgerätes zumindest in einer Schaltstellung überragenden Schaltstellungsanzeiger, dessen Verstellweg gegenüber dem des Kontaktbrückenträgers mittels eines Schnappmechanismis vergrößert ist.The invention relates to an electromagnetic switching device with a switching position indicator which is actuated directly by the contact bridge support and which projects beyond the contour of the switching device at least in a switching position, the displacement of which is increased compared to that of the contact bridge support by means of a snap mechanism.

Bei einem bekannten Schaltgerät der obengenannten Art (DE-C-963170) wird durch den Kontaktbrückenträger beim Einschalten ein Schaltstellungsanzeiger mitgenommen, der nach Beendigung des Weges des Kontaktbrückenträgers über einen federbelasteten Schieber, der auf eine schiefe Ebene einwirkt, um einen gewissen Bereich weiterbewegt wird. Wird die Spule des elektromagnetischen Schaltgerätes spannungslos, so geht zwar der Kontaktbrückenträger in die Ausgangslage zurück und die Kontakte werden geöffnet, der Schaltstellungsanzeiger verbleibt jedoch in der Ein-Stellung und muß erst durch Handbetätigung des Schiebers aufgrund des Eigengewichtes des Schaltstellungsanzeigers in die Ausgangslage zurückgebracht werden. Mit dieser Anordnung kann somit mit Sicherheit nur die Ein-Funktion aber nicht die Aus-Funktion des Gerätes angezeigt werden.In a known switching device of the above-mentioned type (DE-C-963170), a switching position indicator is taken along by the contact bridge carrier when switched on, which is moved by a certain range after the path of the contact bridge carrier has ended via a spring-loaded slide which acts on an inclined plane. If the coil of the electromagnetic switching device is de-energized, the contact bridge carrier returns to the starting position and the contacts are opened, but the switch position indicator remains in the on position and must only be returned to the starting position by manual operation of the slide due to the weight of the switch position indicator. With this arrangement, only the on function but not the off function of the device can be displayed with certainty.

Es ist weiterhin ein Schaltstellungsgeber für elektrische Schalter bekannt (DE-B-1 590 211), bei dem an einer Meldeschalterwelle eine Feder angreift, die ihn in die Mittellage zieht und bei dem eine Kuppelstange über Anschläge mit einem an einem Schwenkhebel angebrachten Zapfen gleitend verbunden ist. Mit dieser Anordnung ist somit lediglich im Endbereich der Bewegung der Kuppelstange eine Betätigung der Schalter durch Auslenkung des Schwenkhebels möglich. Die Bewegung des Meldeschalters kann hier somit nicht größer sein als die Bewegung des Schalters selbst. Ein derartiger Schaltstellungsgeber ist somit lediglich für Schalter mit großem Hub verwendbar.A switch position transmitter for electrical switches is also known (DE-B-1 590 211), in which a spring acts on a signaling switch shaft, which pulls it into the central position, and in which a coupling rod is slidably connected via stops to a pin attached to a pivoting lever is. With this arrangement, actuation of the switches by deflecting the pivoting lever is thus only possible in the end region of the movement of the coupling rod. The movement of the signaling switch can therefore not be greater than the movement of the switch itself. Such a switch position transmitter can therefore only be used for switches with a large stroke.

Es ist weiterhin bei elektromagnetischen Schaltgeräten bekannt, entweder die Schaltstellungsanzeige einstückig mit dem Kontaktbrückenträger zu verbinden (DE-U-7327169) oder die entgegen der Anzeigerichtung durch Federkraft belastete Schaltstellungsanzeige nach Durchlaufen eines gewissen Weges des Kontaktbrückenträgers von diesem direkt mitnehmen zu lassen (DE-U-7 230 068, DE-U-7196 559). Bei der erstgenannten Ausführung ist zwar eine direkte Anzeige der Stellung des Kontaktbrückenträgers durch die Schaltstellungsanzeige gewährleistet, da jedoch die Schaltwege der Kontaktbrückenträger häufig relativ klein sind, ist aus der Lage der Schaltstellungsanzeige nicht in allen Fällen eine eindeutige Aussage über den Schaltzustand des Schaltgerätes herauszulesen. Dieser Zustand wird bei den zuletzt genannten Schaltgeräten noch verschlimmert, da hier ein Teil des Verschiebeweges des Kontaktbrückenträgers ohne Bewegung der Schaltstellungsanzeige erfolgt. Bei dieser Schaltgeräteausführung ist weiterhin keine direkte Kopplung zwischen Schaltstellungsanzeige und Kontaktbrückenträger vorhanden, so daß eine verklemmte Schaltstellungsanzeige den Ausschaltzustand des Gerätes signalisieren würde, obwohl dies bereits wieder eingeschaltet ist.It is also known in electromagnetic switching devices to either connect the switch position indicator in one piece to the contact bridge support (DE-U-7327169) or to have the switch position indicator, which is loaded by spring force against the display direction, take it directly with it after it has traveled a certain distance (DE-U -7 230 068, DE-U-7196 559). In the first-mentioned embodiment, a direct display of the position of the contact bridge carrier is guaranteed by the switching position indicator, but since the switching paths of the contact bridge carrier are often relatively small, the position of the switching position indicator does not always provide clear information about the switching state of the switching device. This condition is exacerbated in the last-mentioned switching devices, since part of the displacement of the contact bridge support takes place without movement of the switch position indicator. In this switchgear version, there is still no direct coupling between the switch position indicator and the contact bridge support, so that a jammed switch position indicator would signal the switch-off status of the device, although this is already switched on again.

Durch die Erfindung soll somit ein Schaltgerät der obengenannten Art geschaffen werden, das zusätzlich die Trennerfunktion/DIN 57660, Teil 107 §2.1.4), d. h. die Hauptschalterfunktion (DIN 57113 §6.2), übernehmen kann, ohne hierbei einen erheblichen Aufwand erbringen zu müssen.The invention is thus intended to provide a switching device of the type mentioned above, which additionally has the isolating function / DIN 57660, part 107 §2.1.4), d. H. can take over the main switch function (DIN 57113 §6.2) without having to make a considerable effort.

Dies wird erfindungsgemäß dadurch erreicht, daß der Schaltstellungsanzeiger mit dem Kontaktbrückenträger sowohl in Ein- als auch in Ausschaltrichtung mit einem Spiel derart gekuppelt ist, daß sowohl beim Öffnen als auch beim Schließen der Schließerkontakte die Mitnahme des Schaltstellungsanzeigers durch den Kontaktbrückenträger erst erfolgt, wenn der Kontaktbrückenträger schon eine bestimmte Wegstrecke zurückgelegt hat und daß diese Wegstrecke beim Öffnen der Schließerkontakte so bemessen ist, daß nach deren Zurücklegen die Kontaktöffnungsstrekke die Trennerfunktionsbedingungen erfüllt.This is achieved according to the invention in that the switch position indicator with the contact bridge carrier is coupled with play in both the on and off direction so that both the opening and closing of the normally open contacts entrain the switch position indicator through the contact bridge carrier only when the contact bridge carrier has already covered a certain distance and that this distance is dimensioned when the normally open contacts are opened so that after they have been covered the contact opening distance fulfills the isolating function conditions.

Ein konstruktiv einfacher Aufbau für die Verbindung mit Spiel ergibt sich, wenn der Schaltstellungsanzeiger mit einem T-förmigen Ansatz in einer das Spiel bestimmenden, rechteckförmigen Aussparung des Kontaktbrückenträgers verschiebbar geführt ist. Als vorteilhaft hat sich herausgestellt, wenn der Schnappmechanismus mittels einer Schnappfeder gebildet ist.A structurally simple structure for the connection with play results if the switch position indicator is displaceably guided with a T-shaped projection in a rectangular cutout of the contact bridge support which determines the play. It has proven to be advantageous if the snap mechanism is formed by means of a snap spring.

Um die Trennerfunktion des Schaltgerätes auf einfache Weise überwachen zu können ist es vorteilhaft, wenn dem Schaltstellungsanzeiger ein zusätzlicher Steuerkontakt zugeordnet ist. Hierdurch können zusätzlich im Falle von sicherheitsrelevanten Kreisen vorgeschaltete Leistungsschalter beim Versagen dieses Schaltgerätes die Trennerfunktion übernehmen. Um zusätzlich eine gewohnte Anzeige Aus/Ein oder 0/1 zur Verfügung zu haben, kann es vorteilhaft sein, wenn der Schaltstellungsanzeiger einen verschwenkbar gelagerten Segmentanzeiger umfaßt.In order to be able to monitor the disconnector function of the switching device in a simple manner, it is advantageous if an additional control contact is assigned to the switching position indicator. In this way, in the case of safety-relevant circuits, upstream circuit breakers can also take over the isolating function if this switching device fails. In order to additionally have a familiar display off / on or 0/1, it can be advantageous if the switch position indicator comprises a pivotably mounted segment indicator.

Zur Erläuterung der Erfindung werden anhand der Zeichnung Ausführungsbeispiele beschrieben und die Wirkungsweise näher erläutert.To explain the invention, exemplary embodiments are described with reference to the drawing and the mode of operation is explained in more detail.

Es zeigen :

  • Figur 1 den prinzipiellen Aufbau des Schaltgerätes mit einer durch einen Schnappmechanismus betätigten Schaltstellungsanzeige,
  • Figur 2 die Anzeige nach Fig. mit zusätzlichem Hilfsteuerkontakt,
  • Figur 3 die Anordnung nach Fig. 1 mit einer zusätzlichen Segmentschaltstellungsanzeige.
Show it :
  • 1 shows the basic structure of the switching device with a switching position indicator actuated by a snap mechanism,
  • FIG. 2 shows the display according to FIG. With an additional auxiliary control contact,
  • Figure 3 shows the arrangement of FIG. 1 with an additional segment switch position indicator.

Das in der Zeichnung dargestellte elektromagnetische Schaltgerät umfaßt einen Kontaktbrückenträger 1, der durch die Kontaktdruckfeder 2 bei Entregen des nicht näher dargestellten magnetischen Antriebes in die Aus-Stellung des Schaltgerätes gedrückt wird. Die Kontaktdruckfeder 3 preßt die im Fenster 4 des Kontaktbrückenträgers 1 verschiebbar geführte Kontaktbrücke 5 auf die Festkontaktteile 6. Im Kontaktbrückenträger 1 können weitere Kontaktbrücken gehaltert werden, wie gestrichelt angedeutet, die mit anderen Festkontaktteilen zusammenwirken können.The electromagnetic switching device shown in the drawing comprises a contact bridge support 1, which by the Kontaktdruckfe 2 is pressed into the off position of the switching device when the magnetic drive (not shown in more detail) is de-energized. The contact pressure spring 3 presses the contact bridge 5, which is displaceably guided in the window 4 of the contact bridge carrier 1, onto the fixed contact parts 6. Further contact bridges can be held in the contact bridge carrier 1, as indicated by dashed lines, which can interact with other fixed contact parts.

Der Schaltstellungsanzeiger 7 ist mit einem T-förmigen Ansatz 8 in einer rechteckförmigen Aussparung 9 verschiebbar geführt. Die rechteckförmige Aussparung 9 hat einen Durchtritt 10 für den Stiel 11 des Schaltstellungsanzeigers 7. Die Wände 12 und 13 bestimmen das Spiel, das der Schaltstellungsanzeiger 7 gegenüber dem Kontaktbrückenträger 1 aufweist. Eine gehäusefest abgestützte Feder 14 sorgt durch ihr Schnappverhalten für den vergrößerten Bewegungsweg des Schaltstellungsanzeigers 7 gegenüber dem Kontaktbrückenträger 1. Die Bewegungsbegrenzung wird bestimmt durch eine Anformung 15, die mit den Anschlägen 16 bzw. 17 der Abdeckung 18 zusammenwirken. Ein Durchbruch 19 dient zum Einhängen eines Vorhängeschlosses, um das Schaltgerät in der Aus-Stellung verriegeln zu können.The switch position indicator 7 is guided with a T-shaped projection 8 in a rectangular recess 9. The rectangular recess 9 has a passage 10 for the stem 11 of the switch position indicator 7. The walls 12 and 13 determine the play that the switch position indicator 7 has with respect to the contact bridge carrier 1. Due to its snap behavior, a spring 14 supported on the housing ensures the increased movement path of the switch position indicator 7 with respect to the contact bridge carrier 1. The movement limitation is determined by a molding 15 which cooperate with the stops 16 and 17 of the cover 18. An opening 19 is used to hang a padlock in order to be able to lock the switching device in the off position.

Der Schaltstellungsanzeiger 7 wird erst mitgenommen, wenn der Kontaktbrückenträger 1 den Weg 20 zurückgelegt hat. In diesem Fall sind die Kriech- und Luftstrecken zwischen den Festkontaktteilen 6 und der Kontaktbrücke 5 so groß, daß die Trennerfunktion erfüllt ist. Durch die Anlage des T-förmigen Ansatzes 8 an der Wand 13 wird bei Weiterbewegung des Kontaktbrückenträgers 1 die Feder 14 über die Totpunktlage gebracht und der Anzeiger springt über die Oberkante der Abdeckung 18 hinaus bis entweder die Anformung 15 am Anschlag 16 anliegt (das ist der Normalfall) oder aber für den Fall, daß die Trennung nicht komplett erfolgte, kann eine Aniage des T-förmigen Ansatzes 8 an der Wand 12 erfolgen, so daß keine definierte Anzeige des Aus-Zustandes nach außen hin erfolgt. Durch Anlage des T-förmigen Ansatzes 8 an der Wand 12 wird der Schaltstellungsanzeiger beim Einschalten des Schaltgerätes in die aus Fig. 1 ersichtliche Lage gezogen. In der Anzeigstellung des Schaltstellungsanzeigers kann durch Einhängen eines Schlosses in den Durchtritt 10 das Einschalten des Schützes blockiert werden, d. h. es ist sichergestellt, daß z. B. während der Durchführung von Wartungsarbeiten an der Maschine das Schaltgerät weder mechanisch noch elektrisch eingeschaltet werden kann.The switch position indicator 7 is only taken along when the contact bridge support 1 has covered the path 20. In this case, the creepage distances and clearances between the fixed contact parts 6 and the contact bridge 5 are so large that the isolating function is fulfilled. Due to the contact of the T-shaped extension 8 on the wall 13, the spring 14 is brought over the dead center position when the contact bridge support 1 moves further and the indicator jumps beyond the upper edge of the cover 18 until either the projection 15 abuts the stop 16 (this is the Normal case) or in the event that the separation did not take place completely, the T-shaped attachment 8 can be arranged on the wall 12, so that there is no defined display of the off state to the outside. By engaging the T-shaped extension 8 on the wall 12, the switch position indicator is pulled into the position shown in FIG. 1 when the switching device is switched on. In the display position of the switching position indicator, the switching on of the contactor can be blocked by hanging a lock in the passage 10, i. H. it is ensured that, for. B. while the maintenance work on the machine, the switching device can be switched on neither mechanically nor electrically.

Im Ausführungsbeispiel nach Fig. 2 sind zusätzlich Hilfssteuerkontakte 21 vorhanden, die von der Anformung 15 des Schaltstellungsanzeigers 7 betätigbar sind. Hierdurch kann die Trennerfunktion überwacht werden. Im Falle von Sicherheitsrelevanten Kreisen können z. B. vorgeschaltete Leistungsschalter oder ähnliches beim Versagen des Schützes die Trennerfunktion übernehmen. Die Ansteuerung geschieht dann über die Hilfssteuerkontakte 21 mit einer zusätzlichen Zeitverzögerung. Die bei Motorschützen üblichen Hilfsschalter sind für eine derartige Überwachungsfunktion nicht geeignet.In the exemplary embodiment according to FIG. 2, auxiliary control contacts 21 are additionally provided, which can be actuated by the molding 15 of the switch position indicator 7. This enables the disconnector function to be monitored. In the case of security-relevant circles, e.g. B. upstream circuit breakers or the like take over the disconnector function when the contactor fails. The control then takes place via the auxiliary control contacts 21 with an additional time delay. The auxiliary switches usual for motor contactors are not suitable for such a monitoring function.

Bei der Ausführungsform nach Fig. 3 wird die Kennzeichnung der Position mit 0 mit I durch den verschwenkbar gelagerten Segmentanzeiger 22 erreicht, die von dem Schaltstellungsanzeiger 7 verschwenkt wird.In the embodiment according to FIG. 3, the position is identified by 0 with I by the pivotably mounted segment indicator 22, which is pivoted by the switch position indicator 7.

Durch die beschriebene Schaltgeräteausführung ist die galvanische Trennung in Sicherheitskreisen mit geringem Aufwand sicherzustellen. Die beschriebene Schaltgeräteausführung gewinnt durch den steigenden Einsatz von Elektronikkreisen zunehmend an Bedeutung, da elektronische Schaltelemente die galvanische Trennung in der Regel nicht erfüllen können.The described switchgear design ensures galvanic isolation in safety circuits with little effort. The switching device design described is becoming increasingly important due to the increasing use of electronic circuits, since electronic switching elements generally cannot meet the electrical isolation.
