Description

Beschreibungdescription
Niederspannungs-Leistungsschalter mit einem eine Vorderwand und eine Rückwand aufweisenden Gehäuse.Low-voltage circuit breaker with a housing having a front wall and a rear wall.
Die Erfindung betrifft einen Niederspannungs-Leistungsschalter mit einem eine Vorderwand und eine Rückwand aufweisenden Gehäuse mit bestimmten Funktionsaufteilungen, wobei die Vor- derwand 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 housing having a front wall and a rear wall with certain functional divisions, the front wall and the rear wall being separated from one another by a separating joint running vertically in the position of use between the housing front wall and the housing rear wall.
Zwischen der Gehäusevorderwand und der Gehäuserückwand befin- den 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 Kunst- stoffformteile, 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.The circuit breakers of the circuit breaker are located between the front wall of the housing and the rear wall of the housing. It is therefore necessary to remove the rear wall of the housing for the purpose of maintenance or repair of the switch contact systems in order to gain access to the corresponding assemblies. This can be done after all screws have been removed that connect the rear wall of the housing directly to the front wall of the housing and to the foot plates. In the case of large low-voltage circuit breakers, the rear wall of the housing and the front wall of the housing are relatively large and locally interleaved plastic molded parts, so that it cannot be avoided that a relatively large amount of force is required to separate the rear wall of the housing from the front wall of the housing. This can lead to a jerky movement of the rear wall of the housing in relation to the front wall of the housing when the two parts tilt or stick together.
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 in the rear wall of the housing are connected to the electronic tripping unit, which is located in front of the housing front wall and controls the protective functions of the circuit breaker. With such a jerky movement or too much effort there is a risk that these connecting lines are also jerky or too heavily stressed and possibly suffer damage or be torn out of their terminals.
Ein Niederspannungs-Leistungsschalter der hier betrachteten herkömmlichen Bauart ist beispielsweise in der US-PS 4,764,650 gezeigt. Dieser Niederspannungs-Leistungs- schalter 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 conventional type considered here is shown, for example, in US Pat. No. 4,764,650. This low-voltage circuit breaker is provided with a vertical joint between the front wall and the rear wall with certain functional divisions and shows the switch elements arranged in the two housing parts.
Das DE-GM 296 15 162 zeigt einen Niederspannungs-Leistungs- schalter mit einem konzentrisch zur Anschlußschiene angeord- neten Stromwandler und einer Verbindungsleitung zum Über- stromauslöser, bei welchem die Schalterrückwand um eine tief- gelegene und im Bereich der Fußbleche angeordnete Schwenkachse nach hinten abklappbar angeordnet ist. Durch diese Anordnung soll die Gefahr einer Beschädigung (abreißen) der emp- findlichen Stromleitungen zwischen den Stromwandlern und den vorn liegenden Überstromauslösern vermieden werden.DE-GM 296 15 162 shows a low-voltage circuit breaker with a current transformer arranged concentrically to the connecting rail and a connecting line to the overcurrent release, in which the switch rear wall can be swung backwards about a low-lying pivot axis arranged in the area of the foot plates is arranged. This arrangement is intended to avoid the risk of damage (tearing off) of the sensitive power lines between the current transformers and the overcurrent releases at the front.
Es ist aber gleichwohl die Gefahr einer ruckartigen oder zu kräftigen Bewegung nicht ausgeschlossen, wenngleich sie nur als Schwenkbewegung der Schalterrückwand auftritt.However, the 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 Verbindungs- leitungen zwischen den Stromwandlern in der Gehäuserückwand und der räumlich der Geäusevorderwand vorgelagerten elektronischen Auslöseeinheit auszuschließen, wenn der Niederspan- nungs-Leistungsschalter zu Wartungs- oder Reparaturzwecken demontiert wird.The object of the present invention is now to endanger or damage the electrical connection exclude cables between the current transformers in the rear wall of the housing and the electronic tripping unit in front of the front wall of the housing when the low-voltage circuit breaker is dismantled for maintenance or repair purposes.
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 wesentli- chen über die gesamte Breite des Niederspannungs-Leistungs- schalters 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 in the case of multi-pole low-voltage circuit breakers with a housing front wall and a housing rear wall, which are separated from one another by a vertical joint in the position of use, an integrated cable duct is provided in the bottom of the housing rear wall, which is located below the contact carrier bearings and of the current transformer chambers surrounding the lower connecting rails, extends essentially over the entire width of the low-voltage circuit breaker and has one or more through openings in the direction of the front wall of the housing for passing the connecting lines between the current transformers and a front-side electronic tripping unit. This cable duct is not cut by other rooms of the low-voltage circuit breaker, but forms a completely separate tunnel. It accommodates all cable harnesses in a room that is separate from the rest of the low-voltage circuit breaker and thus avoids the risk of damage to the cables during assembly, repair and maintenance work on the switch.
Der Kabelkanal ist mit einer Abdeckplatte verschlossen, die aus einem dünnen und elastischen Material mit einer ausreichenden Festigkeit gegen ein Durchdrücken in den Kabelkanal besteht. Ein geeignetes Material kann zweckmäßig ein Hartgewebe sein. Zur Aufnahme der Abdeckplatte für den Kabelkanal ist im Boden der Gehäuserückwand eine gehäuseseitige Nut mit einer in der Nut vorstehenden über die gesamte Länge des Kabelkanals verlaufenden Nase vorgesehen, in welche die Abdeckplatte zum Verschließen des Kabelkanals eingerastet werden kann.The cable duct is closed with a cover plate, which consists of a thin and elastic material with sufficient strength against being pressed into the cable duct. A suitable material can suitably be a hard tissue. To accommodate the cover plate for the cable duct, a housing-side groove is provided in the bottom of the rear wall of the housing with a nose extending in the groove over the entire length of the cable duct and into which the cover plate can be snapped in order to close the cable duct.
Vorzugsweise ist die Abdeckplatte zur Montage und Demontage mit einer oder mehreren Demontageöffnungen versehen. Die Abdeckplatte kann mit Hilfe dieser Demontageöffnungen ohne Zu- hilfenahme von Werkzeugen in die Nut eingesetzt und herausgenommen werden, wobei die Nase ein Durchdrücken der Abdeckplatte in den Kabelkanal verhindert .The cover plate is preferably provided with one or more disassembly openings for assembly and disassembly. With the help of these disassembly openings, the cover plate can be inserted into and removed from the groove without the use of tools, the nose preventing the cover plate from being pushed into the cable duct.

Dieser Kabelkanal 11 erstreckt sich, wie in der Fig. 2 zu erkennen ist, im Boden 12 der Gehäuserückwand 3 des Niederspan- nungs-Leistungsschalters 1 unterhalb der nicht sichtbaren Kontaktträgerlagerungen und der die unteren Anschlußschienen 5 umgebenden, in der Darstellung abgedeckten Stromwandlerkammern 6, im wesentlichen über die gesamte Breite des Niederspannungs-Leistungsschalters 1. In der Richtung zur Gehäusevorderwand 2 weist der Kabelkanal 11 eine Durchtrittsöffnung 13 zum Hindurchführen der Verbindungsleitungen zwischen den Stromwandlern und einer strichpunktiert angedeuteten elektronischen Auslöseeinheit 18 auf .This cable duct 11 extends, as can be seen in FIG. 2, in the floor 12 of the rear wall 3 of the low-voltage circuit breaker 1 below the invisible contact carrier bearings and the current transformer chambers 6 surrounding the lower connecting rails 5, shown in the illustration, in essentially over the entire width of the low-voltage circuit breaker 1. In the direction of the front wall 2 of the housing, the cable duct 11 has a passage opening 13 for the passage of the connecting lines between the current transformers and an electronic tripping unit 18 indicated by dash-dotted lines.
In einer gehäuseseitigen Nut 14 im Boden 12 der Gehäuserück- wand 3, die in der Fig.3 schematisch als Detail dargestellt ist und welche eine in der Nut 14 vorstehende über die gesamte Länge des Kabelkanals 11 verlaufende 15 aufweist, kann eine in der Fig.4 als mögliche Ausführungsform dargestellte Abdeckplatte 16 zum Verschließen des Kabelkanals 11 eingerastet werden. Diese Abdeckplatte 16, welche beispielsweise ausIn a groove 14 on the housing side in the base 12 of the rear wall 3 of the housing, which is shown schematically as a detail in FIG. 3 and which has a protruding 15 in the groove 14 over the entire length of the cable duct 11, one in FIG. 4 cover plate 16 shown as a possible embodiment can be snapped into place to close the cable duct 11. This cover plate 16, which for example from
Hartgewebe hergestellt ist, ist zur Montage und Demontage mit zwei Demontageöffnungen 17 versehen. Die Abdeckplatte 16 kann mit Hilfe dieser Demontageöffnungen 17 ohne Zuhilfenahme von Werkzeugen in die Nut 14 eingesetzt und herausgenommen werden, wobei die Nase 15 ein Durchdrücken der Abdeckplatte 16 in den Kabelkanal 11 verhindert .Hard tissue is made, is provided for assembly and disassembly with two disassembly openings 17. The cover plate 16 can with the help of these disassembly openings 17 without the aid of Tools are inserted and removed in the groove 14, the nose 15 preventing the cover plate 16 from being pushed into the cable duct 11.

Es ist eine problemlose Zerlegung des Leistungs- Schalters zu Reparatur- und Wartungsarbeiten ohne Gefährdung der Kabel möglich. The advantage of this arrangement is that channels can be provided for the cables from the sensors to the overcurrent release and display instruments during the manufacture of the housing parts, in which the cables cannot be damaged. The circuit breaker can be easily dismantled for repair and maintenance work without endangering the cables.
