Description
Die Erfindung betrifft eine Lichtbogenlöscheinrichtung für ein in Luft schaltendes Niederspannungs-Schaltgerät, mit einem Löschbleche aufweisenden Löschraum und mit einem den Löschraum abdeckenden, mit Auslassöffnungen für Schaltgase versehenen Deckel, sowie mit einer wahlweise verwendbaren gesonderten, Entionisierungsmittel aufweisenden Kühleinrichtung für die Schaltgase.The invention relates to an arc quenching device for a switching in air low-voltage switching device, with a quenching extinguishing space and with a quenching space, provided with outlet openings for switching gases lid, as well as with an optional separate, deionizing means having cooling device for the switching gases.
In Luft schaltende Niederspannungsschaltgeräte, wie Niederspannungs-Leistungsschalter, benötigen zum Betrieb eine Lichtbogenlöscheinrichtung, in Form von Löschkammern zur Abkühlung und Löschung von Schaltlichtbögen, die bei der Kontakttrennung auftreten. Um eine Beeinträchtigung des Leistungsschalters selbst und angrenzender Anlagenteile oder sonstiger Baugruppen zu verhindern, müssen die Schaltlichtbögen von anderen Komponenten des Leistungsschalter ferngehalten werden und die heißen und somit ionisierten Schaltgase müssen vor ihrem Austritt aus der Löschkammer soweit abgekühlt werden, dass in der Umgebung des Schaltgerätes keine elektrischen Überschläge oder andere Schäden auftreten. Jede Lichtbogenlöschkammer enthält im allgemeinen eine Vielzahl von zwischen zwei Seitenwänden angeordneten Löschblechen, die zur Abkühlung und Löschung des Lichtbogens beitragen. Oberhalb der Löschbleche befindet sich ein Deckel mit Auslassöffnungen für Schaltgase.Low-voltage, air-switching devices, such as low-voltage circuit breakers, require an arc-quenching device in operation, in the form of quenching chambers, for quenching and extinguishing switching arcs that occur during contact separation. To prevent deterioration of the circuit breaker itself and adjacent parts of the system or other assemblies, the switching arcs must be kept away from other components of the circuit breaker and the hot and thus ionized switching gases must be cooled before they leave the extinguishing chamber so far that in the environment of the switching device no electrical flashovers or other damage. Each arc quenching chamber generally includes a plurality of quenching plates disposed between two sidewalls, which contribute to the cooling and extinguishing of the arc. Above the quenching plates there is a cover with outlet openings for switching gases.
Die Einbauorte von Niederspannungs-Leistungsschaltern können sehr unterschiedlich sein. Hiervon hängt es ab, welche Temperatur und welchen Grad von Ionisierung die aus den Lichtbogenlöscheinrichtungen austretenden Schaltgase haben dürfen. Um diese unterschiedlichen Bedingungen zu berücksichtigen, werden Lichtbogenlöscheinrichtungen in einer normalen Ausführung für standardmäßige Anforderungen hergestellt, die bei Bedarf durch einer gesonderte Kühleinrichtung für die Schaltgase ergänzt werden können. Dabei kann es vorkommen, dass sich ein Bedarf an einer verbesserten Kühlung der Schaltgase erst nach Errichtung einer Schaltanlage herausstellt, z. B. aufgrund einer veränderten Betriebsweise oder aufgrund des Einsatzes anderer Verbraucher mit dem Ergebnis, dass es zu Schaltungen mit höherer Leistung und einer entsprechend größeren Menge von Schaltgasen kommt.The installation locations of low-voltage circuit breakers can be very different. It depends on this, what temperature and what degree of ionization that from the arc extinguishing equipment may have exiting switching gases. To account for these different conditions, arc quenching systems are manufactured in a standard design for standard requirements, which can be supplemented if necessary by a separate cooling device for the switching gases. It may happen that a need for improved cooling of the switching gases turns out after the establishment of a switchgear, z. B. due to a change in operation or due to the use of other consumers with the result that it comes to circuits with higher power and a correspondingly larger amount of switching gases.
