Description

Die Erfindung betrifft einen Schütz mit einer energieeffizienten Spulenansteuerung.The invention relates to a contactor with an energy-efficient coil drive.

Ein Schütz arbeitet üblicherweise nach dem Prinzip eines Elektromagneten. Ein Strom in der Erregerspule erzeugt einen magnetischen Fluss durch einen ferromagnetischen Kern und einen beweglich gelagerten ferromagnetischen Anker. An einem Luftspalt kommt es zur Krafteinwirkung auf den Anker, wodurch dieser einen oder mehrere Kontakte des Schaltelements schaltet. Üblicherweise wird der Anker durch Federkraft in die Ausgangslage zurückgestellt, sobald die Spule nicht mehr erregt ist. Das Öffnen oder das Schließen des Schaltelements wird über die Erregung der Spule gesteuert. Durch das Erregen der Spule wird ein mit dem Anker verbundener beweglich gelagerter Kontakt mit einem Festkontakt des Schaltelements elektrisch leitend verbunden oder vom Festkontakt elektrisch getrennt. Im geschlossenen Zustand des Schaltelements wird die über das Schaltelement geführte Energieversorgung des Stromkreises aufrecht erhalten. Im geöffneten Zustand wird die über das Schaltelement geführte Energieversorgung des Stromkreises unterbrochen.A contactor usually works on the principle of an electromagnet. A current in the excitation coil generates a magnetic flux through a ferromagnetic core and a movably mounted ferromagnetic armature. At an air gap, there is a force acting on the armature, whereby this one or more contacts of the switching element switches. Usually, the armature is returned by spring force to the starting position as soon as the coil is no longer energized. The opening or closing of the switching element is controlled by the excitation of the coil. By energizing the coil connected to the armature movably mounted contact with a fixed contact of the switching element is electrically conductively connected or electrically isolated from the fixed contact. In the closed state of the switching element, the guided over the switching element power supply of the circuit is maintained. In the open state, the guided over the switching element power supply of the circuit is interrupted.

Schütze werden immer mehr mittels einer speicherprogrammierbaren Steuerung (SPS) angesteuert. Die Ausgänge dieser SPS bestehen zunehmend aus Halbleitern mit einer maximalen Strombelastung von 0,5 oder 2A bei 24V und einem DC-Strom. Auf Grund von Energie- und Ressourceneinsparungen werden Schütze immer mehr mit integrierten elektronischen Spulenansteuerungen ausgestattet. Diese haben eine sehr hohe kurzzeitige Anzugsleistung, die allerdings im Vergleich zu konventionellen Schützen konstant ist. Die Energieeinsparung findet in der Halteperiode statt.Contactors are increasingly controlled by means of a programmable logic controller (PLC). The outputs of this PLC are increasingly made of semiconductors with a maximum current load of 0.5 or 2A at 24V and a DC current. Due to energy and resource savings, contactors are increasingly equipped with integrated electronic coil controls. These have a very high short-term tightening performance, which, however, is constant in comparison to conventional shooters. The energy saving takes place in the holding period.

Im Stand der Technik gab es bisher klassische DC-Antriebe ohne elektronische Spulenansteuerung. Diese werden kontinuierlich vom Strom durchflossen, so dass Fehlermeldungen ausgeschlossen waren.In the prior art, there were previously classic DC drives without electronic coil control. These are continuously flowed through, so that error messages were excluded.

Um das Problem bei elektronisch gesteuerten Antrieben zu lösen, wird häufig ein Widerstand parallel zum Schütz angeschlossen. Der Nachteil hierbei ist, dass der Strom ständig durch diese Widerstände fließt, so dass es also zum Einen zu einer Erwärmung kommt und zum Anderen zu einer unnützen Verlustleistung.To solve the problem with electronically controlled drives, a resistor is often connected in parallel to the contactor. The disadvantage here is that the current is constantly flowing through these resistors, so that it comes on the one hand to a warming and on the other to a useless power loss.

Demgemäß besteht die Aufgabe der vorliegenden Erfindung darin, einen Schütz mit einer energieeffizienten elektronischen Spulenansteuerung zu schaffen.Accordingly, the object of the present invention is to provide a contactor with an energy efficient electronic coil drive.

Diese Aufgabe wird erfindungsgemäß durch einen Schütz mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind der Gegenstand der abhängigen Ansprüche.This object is achieved by a contactor with the features of claim 1. Advantageous embodiments and developments, which can be used individually or in combination with each other, are the subject of the dependent claims.

Erfindungsgemäß wird diese Aufgabe durch einen Schütz mit einer energieeffizienten Spulenansteuerung gelöst, wobei die Spulenansteuerung Anschlüsse A1/A2 aufweist, welche nach Anlegen einer Steuerspannung eine Spule mittels Einschaltimpuls ansteuern, welcher von einem Komparator 1 ausgebildet ist und wobei ein Komparator 2 als Multivibrator ausgebildet ist und wobei die Komparatoren 1 und 2 ausgangsseitig abwechselnd Feldeffekttransistoren FET1 und FET2 ansteuern.According to the invention this object is achieved by a contactor with an energy-efficient coil drive, wherein the coil drive terminals A1 / A2, which drive by applying a control voltage, a coil by turn-on, which is formed by a comparator 1 and wherein a comparator 2 is designed as a multivibrator and wherein the comparators 1 and 2 on the output side alternately drive field effect transistors FET1 and FET2.

Nach dem Anlegen der Steuerspannung an die Schützanschlüsse A1/A2 wird die Magnetspule mittels Einschaltimpuls in voller Höhe (maximaler Strom) angesteuert. Dieser Einschaltimpuls wird mittels Komparator 1 erzeugt, die Impulslänge ist dabei variabel. Dazu wird vom Komparator 1 zuerst ein High- Signal Ausgegeben und im Anschluss dauerhaft LOW. Der Komparator 2 arbeitet als Multivibrator. Durch geeignete Beschaltung des Komparators kann die Schaltfrequenz und auch die Stromflussdauer durch die Schützspule eingestellt werden. Die beiden Komparatorausgänge steuern Feldeffekttransistoren FET1 und FET2 (MOSFETs) an, die im Spulenstromkreis parallel geschaltet sind. Ist der FET 1 leitend, wird der FET 2 (der die PWM erzeugt) überbrückt, der Einschaltimpuls wirkt in voller Höhe. Nach Ablauf des Einschaltimpulses sperrt FET 1, es wirkt nun ausschließlich die PWM auf die Spule. Mit dieser Schaltungsanordnung lässt sich die Halteleistung auf frei wählbare Werte reduzieren.After applying the control voltage to the contactor terminals A1 / A2, the solenoid is controlled by means of switch-on pulse in full (maximum current). This switch-on pulse is generated by means of comparator 1, the pulse length is variable. For this purpose, the comparator 1 first outputs a high signal and then LOW permanently. The comparator 2 works as a multivibrator. By suitable wiring of the Comparator, the switching frequency and the current flow through the contactor coil can be adjusted. The two comparator outputs drive field effect transistors FET1 and FET2 (MOSFETs), which are connected in parallel in the coil circuit. If the FET 1 is conducting, the FET 2 (which generates the PWM) is bypassed, the switch-on pulse acts in full. After the switch-on pulse has expired, FET 1 blocks, and now only the PWM acts on the coil. With this circuit arrangement, the holding power can be reduced to freely selectable values.

Mit dieser Schaltung kann eine grundlegende Anforderung an DC- Schütze umgesetzt werden. Die Anforderung besteht in der Reduzierung der Halteleistung der Schützspule ohne zusätzliche Verlustwärme. Diese Schaltung lässt sich auf kleinstem Raum platzieren. Sie ist sehr kostengünstig, da nur ein Zweifach-Komparator, 2 FETs und wenige Widerstände bzw. Kondensatoren notwendig sind. Ein weiterer großer Vorteil besteht darin, dass auf einen Controller mit entsprechender Firmware verzichtet werden kann. Diese Schaltung kann bei Bedarf auch als externes Vorschaltelement an Standard- DC- Schütze angebaut werden.This circuit can be used to implement a basic requirement for DC contactors. The requirement is to reduce the holding power of the contactor coil without additional heat loss. This circuit can be placed in the smallest space. It is very cost effective, since only a dual comparator, 2 FETs and a few resistors or capacitors are necessary. Another big advantage is that you can do without a controller with the appropriate firmware. If required, this circuit can also be mounted as an external ballast on standard DC contactors.

In einer weiteren speziellen Fortführung des erfindungsgemäßen Konzepts kann es vorgesehen sein, dass der mittels Komparator 1 erzeugte Einschaltimpuls variabel ist.In a further specific continuation of the inventive concept, it can be provided that the switch-on pulse generated by means of comparator 1 is variable.

Eine erfindungsgemäße Weiterführung dieses Konzepts kann darin bestehen, dass vom Komparator 1 zur Erzeugung eines Schaltimpulses zuerst ein High-Signal und anschließend dauerhaft ein Low-Signal erzeugt wird.An inventive continuation of this concept may consist in that the comparator 1 for generating a switching pulse first a high signal and then permanently a low signal is generated.

In einer besonders vorteilhaften Ausgestaltung der Erfindung kann es vorgesehen sein, dass die Beschaltung am Komparator 2 derart ausgebildet ist, dass Schaltfrequenz und Stromflussdauer durch die Magnetspule einstellbar ist.In a particularly advantageous embodiment of the invention, it may be provided that the circuit is formed on the comparator 2 such that the switching frequency and current flow time is adjustable by the magnetic coil.

Es ist außerdem vorteilhaft, wenn mindestens ein Feldeffekttransistor FET1 oder FET2 als MOSFET ausgebildet ist.It is also advantageous if at least one field effect transistor FET1 or FET2 is designed as a MOSFET.

In einer weiteren speziellen Fortführung des erfindungsgemäßen Konzepts kann es vorgesehen sein, dass die Feldeffekttransistoren FET1 und FET2 im Spulenstromkreis parallel geschaltet sind.In a further specific continuation of the inventive concept, it may be provided that the field-effect transistors FET1 and FET2 are connected in parallel in the coil circuit.

Eine erfindungsgemäße Weiterführung dieses Konzepts kann darin bestehen, dass bei Ansteuerung des Feldeffekttransistors 1 der Feldeffekttransistor 2 überbrückt geschaltet ist.An inventive continuation of this concept may consist in that when driving the field effect transistor 1, the field effect transistor 2 is connected bridged.

In einer besonders vorteilhaften Ausgestaltung der Erfindung kann es vorgesehen sein, dass nach Ablauf des Einschaltimpulses der Feldtransistoreffekt FET1 gesperrt ist.In a particularly advantageous embodiment of the invention, it may be provided that the field transistor effect FET1 is blocked after the switch-on pulse has expired.

Es ist außerdem vorteilhaft, wenn nach Ablauf des Einschaltimpulses ausschließlich eine Pulsweitenmodulation auf die Spule wirkt.It is also advantageous if after expiration of the switch-on pulse only a pulse width modulation acts on the coil.

In einer weiteren speziellen Fortführung des erfindungsgemäßen Konzepts kann es vorgesehen sein, dass die Spulenansteuerung mit einer frei wählbaren Halteleistung ausgebildet ist.In a further specific continuation of the inventive concept, it can be provided that the coil drive is designed with a freely selectable holding power.

In einer weiteren speziellen Fortführung des erfindungsgemäßen Konzepts kann es vorgesehen sein, dass diese Spulenansteuerung in einem externen Vorschaltelement an einen Standard- DC- Schütz ausgebildet ist.In a further specific continuation of the inventive concept it can be provided that this coil drive is formed in an external ballast to a standard DC contactor.

Dieser Einschaltimpuls wird mittels eines Komparators 1 erzeugt, die Impulslänge ist dabei variabel. Dazu wird vom Komparator 1 zuerst ein High-Signal ausgegeben und anschließend dauerhaft LOW. Ein weiterer Komparator 2 arbeitet als Multivibrator. Durch geeignete Beschaltung des Komparators 2 kann die Schaltfrequenz und ebenso die Stromflussdauer durch die Spule eingestellt werden. Ausgangsseitig steuern die beiden Komparatoren 1 und 2 Feldeffekttransistoren FET1 und FET2, insbesondere MOSFETs an, welche vorzugsweise im Spulenstromkreis parallel geschaltet sind. Ist der Feldeffekttransistor FET 1 leitend, wird der Feldeffekttransistor FET 2, welcher die Pulsweitenmodulation (PWM) erzeugt, überbrückt, so dass der Einschaltimpuls in voller Höhe wirkt. Nach Ablauf des Einschaltimpulses sperrt der Feldeffekttransistor FET 1, es wirkt nun ausschließlich die PWM des Feldeffekttransistors FET 2 auf die Spule. Mit dieser Schaltungsanordnung lässt sich die Halteleistung auf frei wählbare Werte reduzieren.The contactor according to the invention with energy-efficient coil drive has connections A1 / A2 which, after the application of the control voltage, drive the coil by means of the switch-on pulse in full (maximum current). This switch-on pulse is generated by means of a comparator 1, the pulse length is variable. For this purpose, the comparator 1 first outputs a high signal and then permanently low. Another comparator 2 works as a multivibrator. By suitable wiring of the comparator 2, the switching frequency and also the current flow time through the coil can be adjusted. On the output side, the two comparators 1 and 2 control field-effect transistors FET1 and FET2, in particular MOSFETs, which are preferably connected in parallel in the coil circuit. If the field effect transistor FET 1 is conductive, the field effect transistor FET 2, which generates the pulse width modulation (PWM), is bridged, so that the switch-on pulse acts in its entirety. After expiration of the switch-on pulse, the field-effect transistor FET 1 blocks, and now only the PWM of the field-effect transistor FET 2 acts on the coil. With this circuit arrangement, the holding power can be reduced to freely selectable values.
