Description

Die Erfindung bezieht sich auf ein Kondensatorschütz, umfassend ein Standardschütz, das Hauptkontakte aufweist, einen Hilfsschalter mit gegenüber den Hauptkontakten voreilenden Hilfskontakten, zu denen jeweils mindestens ein Widerstandsdraht in Reihe geschaltet ist, wobei die Reihenschaltung aus je einem Hilfskontakt und mindestens einem Widerstandsdraht phasenweise zu jeweils einem Hauptkontakt parallel geschaltet ist, und Eingangs- und Ausgangsklemmen zur elektrischen Ankopplung der Reihenschaltungen an die Hauptkontakte.The invention relates to a capacitor contactor, comprising a standard contactor with main contacts, one Auxiliary switch with lead over the main contacts Auxiliary contacts, each of which has at least one resistance wire is connected in series, the series connection being off one auxiliary contact each and at least one resistance wire connected in phases to a main contact in parallel is, and input and output terminals for electrical coupling the series connections to the main contacts.

Ein gattungsgemäßes Kondensatorschütz gehört seit langem zum Lieferumfang der Anmelderin. FIG 6 zeigt die prinzipielle elektrische Schaltung eines Kondenatorschützes K. Dabei sind parallel zur Hauptkontakten HK eines Standardschützes voreilende Hilfskontakte VK eines Hilfsschalters geschaltet. Die Verbindungsleitungen von den Hilfskontakten VK zu den Hauptkontakten HK sind als Widerstandsdrähte mit dem Widerstand Rv ausgeführt. Dabei dienen Einzeleingangsklemmen 1,3,5 und Einzelausgangsklemmen 2,4,6 zum Anschluß der Hauptleiter an das Standardschütz sowie zur Ankopplung der Widerstandsdrähte. Bei Einschaltung einer Kondensatorlast 7 über das Kondensatorschütz gemäß FIG 6 werden zunächst die voreilenden Hilfskontakte VK des Hilfsschalters geschlossen und damit der kurzschlußartige Stromstoß durch die in diesem Strompfad liegenden Widerstände Rv begrenzt. Erst mit Zeitverzug werden dann die Hauptkontakte HK geschlossen.A generic capacitor contactor has long been part of the scope of delivery of the applicant. 6 shows the basic electrical circuit of a capacitor contactor K. Leading auxiliary contacts VK of an auxiliary switch are connected in parallel to the main contacts HK of a standard contactor. The connecting lines from the auxiliary contacts VK to the main contacts HK are designed as resistance wires with the resistor R v . Single input terminals 1,3,5 and single output terminals 2,4,6 are used to connect the main conductors to the standard contactor and to connect the resistance wires. When a capacitor load 7 is switched on via the capacitor contactor according to FIG. 6, the leading auxiliary contacts VK of the auxiliary switch are first closed and thus the short-circuit current surge is limited by the resistors R v located in this current path. The main contacts HK are only closed after a delay.

Üblicherweise werden die Widerstandsdrähte lose in mehreren Schlaufen entsprechend der für den Widerstandswert erforderlichen Länge geführt und die Enden an die Einzeleingangsklemmen und Einzelausgangsklemmen angeschlossen. The resistance wires are usually loosely divided into several Loops according to those required for the resistance value Length led and the ends to the individual input terminals and single output terminals connected.

Die DE 31 05 117 C2 offenbart ein elektromagnetisches Schaltgerät mit haupt- und voreilenden Kontakten, die mit Dämpfungsvorwiderständen bei kapazitiver Belastung zusammengeschaltet sind. Auf der Abgangsseite der haupt- bzw. voreilenden Kontakte 2 bzw. 3 sind Widerstände 14 mit ihren Enden in die Klemmen jeweils eines haupt- und eines voreilenden Kontaktes eingeklemmt. Die Widerstände sind als Drahtwickel ausgebildet und isoliert ausgeführt und liegen zwischen jeweils zwei Teilungsrippen des Gehäuses geschützt gegen äußere Einflüsse.DE 31 05 117 C2 discloses an electromagnetic switching device with main and leading contacts, with damping resistors interconnected at capacitive load are. On the outgoing side of the main or leading Contacts 2 and 3 are resistors 14 with their ends in the terminals of a main and a leading contact trapped. The resistors are designed as wire coils and run in isolation and lie between each two dividing ribs of the housing protect against external influences.

In der FR 27 35 279 A3 ist ein Schaltgerät mit einer Abdekkung beschrieben, an dessen Innenseite flaches Widerstandsmaterial mäanderförmig verlegt ist.In FR 27 35 279 A3 there is a switching device with a cover described, on the inside of flat resistance material is laid in a meandering shape.

Außerdem ist ein Anbaugehäuse mit Bauelementen zum Anbauen an ein elektrisches Gerät mit Anschlußklemmen, vorzugsweise ein Schütz, bekannt (siehe DE 91 00 244 U1). Die elektrischen Bauelemente dienen zur Beschaltung einer Betätigungsspule. Zum Verbinden der Bauelemente mit einem Spulenanschluß ist eine flexible Anschlußleitung vorgesehen.There is also an attachment housing with components for attachment an electrical device with terminals, preferably a Schütz, known (see DE 91 00 244 U1). The electrical Components are used to connect an actuating coil. To connect the components with a coil connection a flexible connection line is provided.

Der Erfindung liegt die Aufgabe zugrunde, ein Kondensatorschütz der obengenannten Art zu schaffen, das einfach aufgebaut und eine einfache und schnelle Montage ermöglicht. Die Aufgabe wird dadurch gelöst, daß die Eingangsklemmen und die Ausgangsklemmen zu einem Eingangsklemmenblock bzw. Ausgangsklemmenblock mit einem Gehäuse zusammengefaßt sind, das jeweils gegeneinander isolierte Kammern aufweist, in denen jeweils eine Anschlußklemme liegt, die mit einem Widerstandsdraht elektrisch verbunden ist, der zur Verbindung mit dem Hilfsschalter aus dem Gehäuse des Eingangsklemmenblocks bzw. Ausgangsklemmenblocks herausgeführt ist und dessen Restlänge im Gehäuse untergebracht ist. The invention has for its object a capacitor contactor of the above kind to create that simple structure and enables easy and quick installation. The Task is solved in that the input terminals and the Output terminals to an input terminal block or output terminal block are summarized with a housing, each has mutually insulated chambers, in each of which there is a connector with a resistance wire is electrically connected to connect to the Auxiliary switch from the housing of the input terminal block or Output terminal block is led out and its remaining length is housed in the housing.

Damit wird die Montage wesentlich erleichtert, denn anstelle mehrerer Einzeleingangsklemmen und Einzelausgangsklemmen sind nunmehr Klemmenblöcke an das Standardschütz anzukoppeln und anzuschließen. Statt mehrerer schlecht handhabbarer Einzelteile ist ein in sich stabiler Anschlußblock vorhanden, der neben den Anschlußklemmen zusätzlich die Widerstandsdrähte aufnimmt. Auf diese Weise kann die Verbindung der Widerstandsdrähte vom Gehäuse des Anschlußblocks zum Hilfsschalter ohne Schlaufenbildung erfolgen, d.h. die bei der Montage hinderlichen Schlaufen entfallen.This makes assembly much easier, because instead of several individual input terminals and single output terminals now connect terminal blocks to the standard contactor and to connect. Instead of several difficult to handle individual parts there is a stable connection block available in addition to the connection terminals, the resistance wires records. In this way, the connection of the resistance wires from the housing of the connection block to the auxiliary switch without loop formation, i.e. the obstacles to assembly Loops are eliminated.

Besonders vorteilhaft ist es, wenn der Widerstandsdraht im Gehäuse des Eingangsklemmenblocks bzw. Ausgangsklemmenblocks in derselben Kammer untergebracht ist, wie die mit ihm elektrisch verbundene Anschlußklemme. Bei dieser Ausführungsform ist der Potentialunterschied des Widerstandsdrahts gegenüber der mit ihm elektrisch verbundenen Anschlußklemme im Vergleich zu benachbarten Anschlußklemmen relativ gering. Zusätzlich wird durch die gegenseitige Isolierung der Kammern die elektrische Beanspruchung und damit die Wahrscheinlichkeit eines Kurzschlusses minimal gehalten.
Eine weitere vorteilhafte Ausführungsform besteht, wenn der Hilfsschalter zusammen mit dem über die Widerstandsdrähte mit ihm verbundenen Eingangs- und Ausgangsklemmenblock als Baueinheit ausgeführt ist, die elektrisch und mechanisch an das Standardschütz ankoppelbar ist. Eine derartige Baueinheit läßt sich mit wenigen Handgriffen mit dem Standardschütz mechanisch und elektrisch verbinden, d.h. der Montageaufwand ist äußerst gering. Falsche Anschlüsse und Verdrahtungen werden nahezu ausgeschlossen.It is particularly advantageous if the resistance wire is accommodated in the housing of the input terminal block or output terminal block in the same chamber as the connecting terminal electrically connected to it. In this embodiment, the potential difference of the resistance wire compared to the connecting terminal electrically connected to it is relatively small compared to neighboring connecting terminals. In addition, the mutual insulation of the chambers keeps the electrical stress and thus the probability of a short circuit to a minimum.
A further advantageous embodiment exists when the auxiliary switch, together with the input and output terminal block connected to it via the resistance wires, is designed as a structural unit which can be electrically and mechanically coupled to the standard contactor. Such a unit can be mechanically and electrically connected to the standard contactor in a few simple steps, ie the assembly effort is extremely low. Incorrect connections and wiring are almost impossible.

Weiterhin erweist es sich als besonders zweckmäßig, wenn die Anschlußklemmen mit einem Anschlußbereich für Leiterquerschnitte bis 70 mm2 und zusätzlich einer Klemme zum Anschluß für Leiterquerschnitte bis 2,5 mm2 ausgeführt sind, um neben einen Hauptleiter- auch einen Hilfsleiteranschluß zu ermöglichen.Furthermore, it proves to be particularly expedient if the connection terminals are designed with a connection area for conductor cross sections of up to 70 mm 2 and additionally a terminal for connection for conductor cross sections of up to 2.5 mm 2 in order to enable not only a main conductor but also an auxiliary conductor connection.

Die Restlänge des Widerstandsdraht 14 ist in Schlaufen in derselben Kammer 19 wie die mit ihm verbundene Anschlußklemme 20 geführt. Die Anschlußklemmen 20 sind gemäß FIG 3 jeweils im unteren Bereich als Bügel 22 geformt und im oberen Bereich als Kontaktklemme 23 mit einer Kombischraube 24 ausgeführt, die über ein Loch 25 an der Oberseite des Gehäuses 18 zugänglich ist. Die elektrische Verbindung des Widerstandsdrahts 14 mit der Anschlußklemme 20 erfolgt, in dem das mit einem Kabelschuh 26 versehene Ende des Widerstandsdrahts 14 an die Kontaktklemme 23 angeschlossen wird. Die Kontaktklemmen 23 dienen zum Anschluß von Hilfsleitern mit einem Leiterquerschnitt bis 2,5 mm2, wozu der Eingangsklemmenblock bzw. Augangsklemmenblock an seiner Frontseite schlitzförmige Einführöffnungen 27 aufweist (siehe FIG 1). Über den als Bügel 22 geformten Bereich sind Hauptleiter mit einem Querschnitt bis zu 70 m2 anschließbar. Der auf der Rückseite des Klemmenblocks 12,13 vorstehende längliche Fortsatz 28 des Bügels 22 dient in Verbindung mit den Hauptleitern zum Anschluß an das Standardschütz 16.The resistance wires 14 have a length corresponding to the desired resistance value and are led out of an opening 21 in the top of the housing 18 in the length required for connection to the auxiliary switches 11. The remaining length of the resistance wire 14 is guided in loops in the same chamber 19 as the connecting terminal 20 connected to it. According to FIG. 3, the connecting terminals 20 are each formed in the lower region as a bracket 22 and in the upper region as a contact terminal 23 with a combination screw 24 which is accessible via a hole 25 on the upper side of the housing 18. The electrical connection of the resistance wire 14 to the connecting terminal 20 takes place by connecting the end of the resistance wire 14 provided with a cable lug 26 to the contact terminal 23. The contact terminals 23 are used to connect auxiliary conductors with a conductor cross section of up to 2.5 mm 2 , for which purpose the input terminal block or output terminal block has slot-shaped insertion openings 27 on its front side (see FIG. 1). Main conductors with a cross section of up to 70 m 2 can be connected via the area shaped as a bracket 22. The elongated extension 28 of the bracket 22 protruding from the rear of the terminal block 12, 13 is used in connection with the main conductors for connection to the standard contactor 16.
