Abstract
Description
Die Erfindung betrifft einen Niederspannungs-Leistungsschalter mit einem eine Vorderwand und eine Rückwand aufweisenden Gehäuse mit bestimmten Funktionsaufteilungen, wobei die Vorderwand und die Rückwand durch eine in der Gebrauchslage vertikal verlaufende Trennfuge zwischen der Gehäusevorderwand und der Gehäuserückwand voneinander getrennt sind.The invention relates to a low-voltage circuit breaker with a front wall and a rear wall Housing with certain functional divisions, with the front wall and the rear wall by a vertical in the use position running joint between the front wall of the housing and the rear wall of the housing are separated.
Zwischen der Gehäusevorderwand und der Gehäuserückwand befinden sich die Schaltkammern des Leistungsschalters. Es ist folglich erforderlich, zum Zweck der Wartung oder der Reparatur der Schaltkontaktsysteme die Gehäuserückwand abzunehmen, um den Zugang zu den entsprechenden Baugruppen zu erhalten. Dies kann geschehen, nachdem alle Schrauben entfernt worden sind, welche die Gehäuserückwand unmittelbar mit der Gehäusevorderwand und mit den Fußblechen verbinden. Bei großen Niederspannungs-Leistungsschaltern handelt es sich bei der Gehäuserückwand und der Gehäusevorderwand um verhältnismäßig große und örtlich verschachtelt ineinandergreifende Kunststoffformteile, so daß nicht zu vermeiden ist, daß zur Trennung der Gehäuserückwand von der Gehäusevorderwand ein relativ großer Kraftaufwand erforderlich ist. Das kann bei einem Verkanten oder Verkleben der beiden Teile miteinander zu einer ruckartigen Bewegung der Gehäuserückwand in Relation zu der Gehäusevorderwand führen.Located between the front wall of the housing and the rear wall of the housing the circuit breakers of the circuit breaker. It is consequently required for the purpose of maintenance or repair to remove the switch contact systems from the back of the housing, to get access to the corresponding assemblies. This can be done after all screws have been removed are which the rear wall of the housing directly with the front wall of the housing and connect with the foot plates. For large low-voltage circuit breakers is the rear wall of the housing and the housing front wall in proportion large and interlocking interlocking molded plastic parts, so that there is no avoiding separation the back of the case from the case front is a relative great effort is required. With one Tilting or gluing the two parts together into one jerky movement of the back wall in relation to the front wall of the housing.
Dabei ist zu beachten, daß sich in der Gehäuserückwand die Stromwandler befinden, die mittels elektrischer Leitungen mit der elektronischen Auslöseeinheit verbunden sind, welche räumlich der Geäusevorderwand vorgelagert ist und die Schutzfunktionen des Leistungsschalters steuert. Bei einer derartigen ruckartigen Bewegung oder einem zu großen Kraftaufwand besteht die Gefahr, daß diese Verbindungsleitungen gleichfalls ruckartig oder zu stark beansprucht werden und möglicherweise Beschädigungen erleiden oder aus ihren Anschlußklemmen herausgerissen werden.It should be noted that the Current transformers are located using electrical cables the electronic release unit are connected, which is spatially in front of the front wall of the housing and the protective functions of the circuit breaker controls. With such a jerky movement or too much effort there is a risk that these connecting lines also jerky or overworked and possibly Suffer damage or from their terminals be torn out.
Ein Niederspannungs-Leistungsschalter der hier betrachteten herkömmlichen Bauart ist beispielsweise in der US-PS 4,764,650 gezeigt. Dieser Niederspannungs-Leistungsschalter ist mit einer vertikalen Fuge zwischen der Vorderwand und der Rückwand mit bestimmten Funktionsaufteilungen versehen und zeigt die zwischen den in beiden Gehäuseteilen angeordneten Schalterelemente.A low voltage circuit breaker of the ones considered here conventional design is for example in the U.S. Patent 4,764,650. This low voltage circuit breaker is with a vertical joint between the front wall and the rear wall with certain functional divisions provided and shows the between those in both housing parts arranged switch elements.
Das DE-GM 296 15 162 zeigt einen Niederspannungs-Leistungsschalter mit einem konzentrisch zur Anschlußschiene angeordneten Stromwandler und einer Verbindungsleitung zum Überstromauslöser, bei welchem die Schalterrückwand um eine tiefgelegene und im Bereich der Fußbleche angeordnete Schwenkachse nach hinten abklappbar angeordnet ist. Durch diese Anordnung soll die Gefahr einer Beschädigung (abreißen) der empfindlichen Stromleitungen zwischen den Stromwandlern und den vorn liegenden Überstromauslösern vermieden werden.DE-GM 296 15 162 shows a low-voltage circuit breaker with one arranged concentrically to the connecting rail Current transformer and a connection line to the overcurrent release, in which the switch rear wall by a low and pivot axis arranged in the area of the foot plates is hinged to the rear. By this arrangement the risk of damaging (tearing off) the sensitive Power lines between the current transformers and the overcurrent releases at the front can be avoided.
Es ist aber gleichwohl die Gefahr einer ruckartigen oder zu kräftigen Bewegung nicht ausgeschlossen, wenngleich sie nur als Schwenkbewegung der Schalterrückwand auftritt.However, there is nevertheless a risk of jerky or too vigorous movement is not excluded, although it only occurs as a pivoting movement of the switch rear wall.
Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine Gefährdung oder Beschädigung der elektrischen Verbindungsleitungen zwischen den Stromwandlern in der Gehäuserückwand und der räumlich der Geäusevorderwand vorgelagerten elektronischen Auslöseeinheit auszuschließen, wenn der Niederspannungs-Leistungsschalter zu Wartungs- oder Reparaturzwecken demontiert wird.The object of the present invention is now a Danger or damage to the electrical connection lines between the current transformers in the rear wall of the housing and the electronic in front of the housing front wall Exclude tripping unit when the low-voltage circuit breaker for maintenance or repair purposes is dismantled.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß insbesondere bei mehrpoligen Niederspannungs-Leistungsschaltern mit einer Gehäusevorderwand und einer Gehäuserückwand, die durch eine in der Gebrauchslage vertikal verlaufende Trennfuge voneinander getrennt sind, im Boden der Gehäuserückwand ein integrierter Kabelkanal vorgesehen ist, der sich unterhalb der Kontaktträgerlagerungen und der die unteren Anschlußschienen umgebenden Stromwandlerkammern, im wesentlichen über die gesamte Breite des Niederspannungs-Leistungsschalters erstreckt und in der Richtung zur Gehäusevorderwand eine oder mehrere Durchtrittsöffnungen zum Hindurchführen der Verbindungsleitungen zwischen den Stromwandlern und einer frontseitigen elektronischen Auslöseeinheit aufweist. Dieser Kabelkanal wird nicht von anderen Räumen des Niederspannungs-Leistungsschalters angeschnitten, sondern bildet einen völlig separaten Tunnel. Er nimmt alle Kabelbäume in einem vom Rest des Niederspannungs-Leistungsschalters getrennten Raum auf und vermeidet somit die Gefahr einer Beschädigung der Kabel bei Montage- Reparatur- und Wartungsarbeiten am Schalter.This object is achieved in that in particular for multi-pole low-voltage circuit breakers with a housing front wall and a housing rear wall, the due to a vertical joint in the position of use are separated from each other in the bottom of the rear wall of the housing an integrated cable duct is provided, which is below the contact carrier bearings and the lower connecting rails surrounding current transformer chambers, essentially across the entire width of the low-voltage circuit breaker extends and in the direction of the front wall of the housing one or more through openings for the passage of the Connection lines between the current transformers and one front electronic release unit. This Cable duct is not from other rooms of the low voltage circuit breaker cut, but forms a completely separate tunnel. It takes all the harnesses in one from the rest of the low-voltage circuit breaker in a separate room and thus avoids the risk of damage to the cables during assembly, repair and maintenance work on the switch.
