Description

Beschreibungdescription
Niederspannungs-Leistungsschalter mit einem elektronischen Uberstromausloser und AuslösemagnetenLow-voltage circuit breaker with an electronic overcurrent release and release magnet
Die Erfindung betrifft einen Niederspannungs-Leistungsschalter mit einem elektronischen Uberstromausloser und mit Auslösemagneten, die aufgrund einer Steuerung durch den Uberstromausloser oder durch ein gesondertes Signal zur Freigabe ge- schlossener Schaltkontakte eine Verklinkung lösen, wobei der Uberstromausloser und die Auslösemagnete zu einem Schutzmodul zusammengefügt sind.The invention relates to a low-voltage circuit breaker with an electronic overcurrent release and with release magnets, which release a latch due to control by the overcurrent release or by a separate signal for releasing closed switching contacts, the overcurrent release and the release magnets being combined to form a protection module.
Ein Leistungsschalter mit den genannten Merkmalen ist durch die US 4,700,161 bekannt geworden. Dieser gehört einer bekannten kompakten Bauart mit Formstoffgehäuse und Kipphebel- antrieb an (MCCB) . Um einen Austausch bzw. eine Nachrüstung von Bausteinen der Auslösemagnete zu ermöglichen, sind diese an der Bedienfront des Leistungsschalters nach Entfernen ei- ner Abdeckung zugänglich. Der elektronische Uberstromausloser besitzt mit Rücksicht auf die kompakte Bauform des Leistungsschalters kein eigenes Bedienpult. Es entspricht gleichfalls der Bauform kompakter Leistungsschalter, dass eine Auslösung nicht durch ein gesondertes Anzeigeorgan, sondern durch eine spezielle Position des äußeren Handgriffes des Kipphebelantriebes für den Benutzer erkennbar ist. Die zum erneuten Einschalten des Leistungsschalters erforderliche Rückstellung (RESET) wird gleichfalls mittels des Handgriffes des Kipphebelantriebes vorgenommen.A circuit breaker with the features mentioned has become known from US 4,700,161. This is part of a well-known compact design with molded plastic housing and rocker arm drive (MCCB). To make it possible to replace or retrofit components of the tripping magnets, they are accessible on the operating front of the circuit breaker after a cover has been removed. The electronic overcurrent release does not have its own control panel due to the compact design of the circuit breaker. It also corresponds to the design of compact circuit breakers that a trip is not recognizable to the user by a separate display element but by a special position of the outer handle of the rocker arm drive. The reset (RESET) required to switch the circuit breaker on again is also carried out using the handle of the rocker arm drive.
Elektronische Uberstromausloser und Auslösemagnete werden sinngemäß in gleicher Weise bei Niederspannungs-Leistungs- schaltern der offenen Bauart (PCB) eingesetzt, die sich ge- genüber der Bauart mit Kipphebelantrieb durch ihre Eignung für höhere Nennströme und höheres Schaltvermögen sowie durch einen Speicherantrieb auszeichnen. Die Uberstromausloser dieser Leistungsschalter bieten ferner die Möglichkeit, alle we- sentlichen Parameter einzustellen, um die Schutzwirkung des Leistungsschalters beispielsweise an die Eigenschaften eines Verbrauchers anpassen zu können. Hierzu sind die Uberstromausloser mit einer eigenen Bedienfront versehen, die in das Bedienpult des Leistungsschalter einbezogen ist und an der die Einstellorgane zugänglich sind. Die Rückstellung nach einer Auslösung erfolgt hier durch ein gesondertes Organ, das in der Nähe der Bedienfront des Überstromauslösers angeordnet ist (Katalog 3WN6, 1995, Seite 2, Siemens-Druckschrift E20002-K1801-B401-A1) .Electronic overcurrent releases and trip magnets are used in the same way for low-voltage circuit breakers of the open type (PCB) that are used Compared to the type with rocker arm drive, they are suitable for higher nominal currents and higher switching capacity, as well as a storage drive. The overcurrent releases of these circuit breakers also offer the possibility of setting all the essential parameters in order, for example, to be able to adapt the protective action of the circuit breaker to the properties of a consumer. For this purpose, the overcurrent release is provided with its own control panel, which is integrated in the control panel of the circuit breaker and on which the setting elements are accessible. The reset after tripping is carried out here by a separate organ, which is located near the operating front of the overcurrent release (catalog 3WN6, 1995, page 2, Siemens publication E20002-K1801-B401-A1).
Der Erfindung liegt die Aufgabe zugrunde, bei einem Leistungsschalter der zuletzt genannten Bauform Auslösemagnete platzsparend unterzubringen und ihre Anzeige- und Rückstell- organe an der Bedienfront des Leistungsschalters Übersicht- lieh anzuordnen.The invention is based on the object of accommodating trip magnets in a circuit breaker of the last-mentioned type in a space-saving manner and of arranging their display and reset elements on the operating front of the circuit breaker in an overview.
Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, dass der elektronische Uberstromausloser in an sich bekannter Weise eine Bedienfront besitzt, die an einem Bedienpult des Leistungsschalters zugänglich ist und dass die Auslösemagnete an der der Bedienfront abgewandten Seite eines Gehäuses des Überstromauslösers an diesem angebracht sind.According to the invention, this object is achieved in that the electronic overcurrent release has a control front in a manner known per se, which is accessible on a control panel of the circuit breaker, and in that the tripping magnets are attached to the side of a housing of the overcurrent release facing away from the control front.
Durch die gegenüber der eingangs genannten US 4,700,161 umge- kehrte Anordnung - Auslösemagnete unter bzw. hinter dem elektronischen Uberstromausloser - wird unter Beibehaltung des Vorteils des konstruktiven Zusammenfassung beider Baugruppen für den Benutzer eine unveränderte Bedienung des elektroni- sehen Überstromauslösers ermöglicht. Andererseits gehören nunmehr die Anzeige- und Bedienorgane der Auslösemagnete zur Bedienfront des Überstromauslösers, wodurch die Übersichtlichkeit und damit die Bediensicherheit erhöht wird. Wesent- lieh ist hierbei, dass durch die Zusammenfassung der insgesamt vorgesehenen Auslösemagnete zu einer am Uberstromausloser angebrachten Baugruppe dementsprechend auch zwei oder auch mehrere Anzeige- und Rückstellorgane für den Benutzer an der Bedienfront des Überstromauslösers sichtbar und zugäng- lieh sind.Due to the reverse arrangement compared to US 4,700,161 mentioned at the outset - release magnets under or behind the electronic overcurrent release - the user is provided with unchanged operation of the electronic circuit while maintaining the advantage of the constructive combination of both modules. see overcurrent release allows. On the other hand, the display and control elements of the release magnets now belong to the control panel of the overcurrent release, which increases the clarity and thus the operational safety. It is essential here that the combination of the overall provided release magnets to form a module attached to the overcurrent release also means that two or more display and reset elements are visible and accessible to the user on the operating front of the overcurrent release.
Die Erfindung wird im Folgenden anhand des in den Figuren dargestellten Ausführungsbeispieles näher erläutert.The invention is explained in more detail below with reference to the embodiment shown in the figures.
Die Figur 1 zeigt eine Seitenansicht eines Schutzmoduls, bestehend aus einem elektronischen Uberstromausloser und einer Baugruppe von Auslösemagneten.FIG. 1 shows a side view of a protection module, consisting of an electronic overcurrent release and an assembly of release magnets.
Die Figur 2 zeigt den oberen Teil einer Bedienfront des Schutzmoduls gemäß der Figur 1.FIG. 2 shows the upper part of an operating front of the protection module according to FIG. 1.
Der Schutzmodul 1 gemäß der Figur 1 besteht aus einem elektronischen Uberstromausloser 2, dessen Gehäuse 3 derart abgestuft ausgebildet ist, dass Auslösemagnete 4 ganz oder teil- weise in der Abstufung Platz finden. Die Auslösemagnete sind in bekannter Weise zu einer Magnetbaugruppe zusammengefasst . Es können insbesondere ein durch den Uberstromausloser 2 zu aktivierender Auslösemagnet sowie ein Unterspannungsauslöser und ein Arbeitsstromauslöser vorhanden sein. Diese zusätzli- chen Auslösemagnete können über eigene Stromkreise aktiviert werden. Jedoch ist es beispielsweise möglich, das Ansprechen solcher zusätzlicher Auslösemagnete in einem Speicherbaustein des elektronischen Überstromauslösers 2 zu registrieren. An einer Bedienfront 5 des Schutzmoduls 1, die in der Figur 2 abgebrochen von vorn gesondert gezeigt ist, befindet sich o- ben ein gesondertes Feld 6 für den Betrieb der Auslösemagne- te. Im gezeigten Baispiel sind ein Anzeigeorgan 7 und einThe protection module 1 according to FIG. 1 consists of an electronic overcurrent release 2, the housing 3 of which is designed in such a way that trip magnets 4 can be accommodated in whole or in part in the gradation. The trigger magnets are combined in a known manner to form a magnet assembly. In particular, a trigger magnet to be activated by the overcurrent release 2 as well as an undervoltage release and a shunt release can be present. These additional tripping magnets can be activated via their own circuits. However, it is possible, for example, to register the response of such additional trigger magnets in a memory module of the electronic overcurrent release 2. On a control front 5 of the protection module 1, which is shown separately broken away from the front in FIG. 2, there is a separate field 6 above for the operation of the triggering magnet. In the example shown, a display element 7 and a are
Rückstellorgan 8 für den vom Uberstromausloser beeinflussten Auslösemagnet 8 vorgesehen sowie gleiche Anzeige- und Bedienorgane 9 bzw. 10 für einen Arbeitsstromauslöser, der beispielsweise beim Ansprechen einer in Reihe mit dem Leistungs- Schalter geschalteten Hochleistungssehmelzsicherung erregt werden kann.Reset element 8 is provided for the release magnet 8 influenced by the overcurrent release, and the same display and control elements 9 and 10 for a shunt release, which can be excited, for example, when a high-performance safety fuse connected in series with the circuit breaker responds.
Die in der Figur 1 gezeigte Magnetbaugruppe mit den Auslöse- magneten 4 kann nach Bedarf bestückt sein, wie dies an sich bekannt ist, und kann zusätzlich Meldeschalter 11 aufweisen, um ein Ansprechen der Auslösemagnete 4 nicht nur mechanisch anzuzeigen, sondern auch elektrisch melden zu können. Ein problemloses Zusammenwirken der an der Rückseite des Gehäuses 3 angeordneten Auslösemagnete 4 mit den an der Bedienfront 5 befindlichen Anzeige- und Rückstellorganen wird dadurch ermöglicht, dass das Bedienfeld 5 das Gehäuse 3 etwas überragt und hierdurch aus der gleichfalls über das Gehäuse 3 etwas überragenden Magnetbaugruppe zur Anzeige und Rückstellung dienende Stifte oder Stößel angeordnet werden können.The magnet assembly shown in FIG. 1 with the release magnets 4 can be equipped as required, as is known per se, and can additionally have signaling switches 11 in order not only to indicate a response of the release magnets 4 mechanically, but also to be able to report them electrically , A problem-free interaction of the release magnets 4 arranged on the rear side of the housing 3 with the display and reset elements located on the operating front 5 is made possible in that the control panel 5 protrudes somewhat beyond the housing 3 and thereby from the magnet assembly, which also somewhat protrudes beyond the housing 3 Display and reset serving pins or plunger can be arranged.
Bei Bedarf können in dem Anzeigefeld 6 auch die Anzeige- und Rückstellorgane von mehr als zwei Auslösemagneten 4 angeordnet sein. Werden, wie in der Figur 2 angedeutet, Auslösemagnete 4 nebeneinander angeordnet, so erleichtert dies die Un- terbringung der Anzeige- und Rückstellorgane 7, 9 bzw. 8 und 10. Der Niederspannungs-Leistungsschalter, der mit dem Schutzmodul ausgerüstet ist, wurde in den Figuren nicht gesondert gezeigt, da er einer an sich bekannten Bauart ange- hört, z. B. entsprechend der erwähnten Siemens-Duckschrift .If required, the display and reset elements of more than two trigger magnets 4 can also be arranged in the display field 6. If, as indicated in FIG. 2, tripping magnets 4 are arranged next to one another, this simplifies the accommodating of the display and reset elements 7, 9 or 8 and 10. The low-voltage circuit breaker, which is equipped with the protection module, has been added to the Figures are not shown separately, since it is of a design known per se. listen, e.g. B. corresponding to the mentioned Siemens print.
Das Zusammenwirken der Auslösemagnete 4 mit den Verklinkungs- elementen im Schaltschloss des Leistungsschalters erfolgt in der gleichen Weise wie bei den bekannten Leistungsschaltern. The interaction of the tripping magnets 4 with the latching elements in the circuit breaker of the circuit breaker takes place in the same way as in the known circuit breakers.
