Der Erfindung geht aus von einem Verfahren zum Betrieb eines Ansteuerkreises eines elektromagnetischen Schalters.The invention is based on a method for operating a drive circuit of an electromagnetic switch.
Aus der
Aus der
In dem bekannten Stand der Technik wird die Funktionstüchtigkeit von Schaltschützen ermittelt, insbesondere wird ein Verschweißungszustand erkannt.In the known prior art, the functionality of contactors is determined, in particular a Verschweißungszustand is detected.
Nachteilig an dem bekannten Stand der Technik ist, dass bei einer Erkennung eines Verschweißungszustandes keine Maßnahmen ergriffen werden, um beispielsweise die Verschweißung zwischen einem Kontaktmittel und einem Kontakt zu trennen.A disadvantage of the known prior art is that no measures are taken in a detection of a welding state, for example, to separate the welding between a contact means and a contact.
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Vorgehensweise mit den kennzeichnenden Merkmalen der unabhängigen Ansprüche weist demgegenüber den Vorteil auf, dass ein Ansteuerkreis eine Erregerspule eines elektromagnetischen Schalters mit einem vorgebbaren Verlauf einer Ansteuerspannung in der Art ansteuert, dass ein mechanisches Rütteln an einem Kontaktmittel des elektromagnetischen Schalters bewirkt wird. Durch das mechanische Rütteln an dem Kontaktmittel wird das Kontaktmittel von mindestens einem Kontakt getrennt.The procedure according to the invention with the characterizing features of the independent claims has the advantage that a drive circuit drives an excitation coil of an electromagnetic switch with a predeterminable course of a drive voltage in the manner that a mechanical shaking is effected on a contact means of the electromagnetic switch. Due to the mechanical shaking on the contact means, the contact means is separated from at least one contact.
Weitere vorteilhafte Ausführungsformen der vorliegenden Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the present invention are the subject of the dependent claims.
Der Ansteuerkreis des elektromagnetischen Schalters umfasst mindestens einen Ansteuerkreisschalter, um den vorgebbaren Verlauf der Ansteuerspannung einzustellen. Der elektromagnetische Schalter umfasst die Erregerspule, welche mittels des Kontaktmittels eine elektrisch leitende Verbindung zwischen mindestens zwei Kontakten herstellt oder trennt. Vorteilhafterweise ist der mindestens eine Ansteuerkreisschalter in dem Ansteuerkreis ein MOSFET oder ein Leistungs-MOSFET, wodurch schnelle Schaltzeiten für den mindestens einen Ansteuerkreisschalter in dem Ansteuerkreis erreicht werden. Vorteilhafterweise ist der elektromagnetische Schalter ein Relais und/oder ein Schütz, der für Schaltvorgänge von hohen Strömen geeignet ist.The drive circuit of the electromagnetic switch comprises at least one Ansteuerkreisschalter to set the predetermined course of the drive voltage. The electromagnetic switch comprises the excitation coil, which establishes or separates an electrically conductive connection between at least two contacts by means of the contact means. Advantageously, the at least one Ansteuerkreisschalter in the drive circuit is a MOSFET or a power MOSFET, whereby fast switching times are achieved for the at least one Ansteuerkreisschalter in the drive circuit. Advantageously, the electromagnetic switch is a relay and / or contactor suitable for high current switching operations.
In einer weiteren vorteilhaften Ausführungsform ist ein Steuergerät vorgesehen, wobei das Steuergerät zum Einstellen der Ansteuerspannung mindestens einen Ansteuerkreisschalter in dem Ansteuerkreis einschaltet oder ausschaltet. Anhand des vorgebbaren Verlaufs der Ansteuerspannung erzeugt das Steuergerät durch Schalten des mindestens einen Ansteuerkreisschalters in dem Ansteuerkreis mindestens einen Schaltimpuls der Ansteuerspannung mit einer vorgebbaren Schaltimpulsdauer und/oder das Steuergerät variiert durch mindestens einen variablen Wiederstand in dem Ansteuerkreis eine Amplitude der Ansteuerspannung, wodurch vorteilhafterweise Auslenkungen des Kontaktmittels während des mechanischen Rüttelns an dem Kontaktmittel variiert werden.In a further advantageous embodiment, a control unit is provided, wherein the control unit for setting the drive voltage turns on or off at least one Ansteuerkreisschalter in the drive circuit. Based on the predeterminable course of the drive voltage, the control unit generates at least one switching pulse of the control voltage with a predeterminable switching pulse duration by switching the at least one Ansteuerkreisschalters and / or the controller varies by at least one variable resistance in the Ansteuerkreis an amplitude of the driving voltage, thereby advantageously deflections of Contact agent can be varied during the mechanical shaking on the contact means.
Vorteilhafterweise kann der vorgebbare Verlauf der Ansteuerspannung an einen Typ des verwendeten elektromagnetischen Schalters und/oder an verwendete Materialien für das Kontaktmittel und den mindestens einen Kontakt und/oder an eine Art einer vorhandenen Verschweißung angepasst werden, beispielsweise durch eine Variation der vorgebbaren Verläufe der Ansteuerspannung und/oder einer Erhöhung der Amplituden der Ansteuerspannung.Advantageously, the predefinable course of the drive voltage can be adapted to a type of electromagnetic switch used and / or to materials used for the contact means and the at least one contact and / or to a type of existing welding, for example by a variation of the predeterminable courses of the drive voltage and / or an increase in the amplitudes of the drive voltage.
In einer weiteren vorteilhaften Ausführungsform ist der Verlauf der Ansteuerspannung so gewählt, dass das Kontaktmittel zu einer Schwingung mit einer Eigenfrequenz des Kontaktmittels angeregt wird. Dadurch werden vorteilhafterweise größere Auslenkungen des Kontaktmittels während des mechanischen Rüttelns an dem Kontaktmittel gegenüber Schwingungen mit einem anderen Verlauf der Ansteuerspannung erreicht.In a further advantageous embodiment, the course of the drive voltage is selected so that the contact means is excited to a vibration with a natural frequency of the contact means. As a result, larger deflections of the contact means during mechanical shaking on the contact means are advantageously achieved with respect to vibrations with a different course of the control voltage.
Eine Erwärmung während eines Betriebes des elektromagnetischen Schalters führt beispielsweise zu einem steigenden Widerstand in der Erregerspule, wodurch ein geringerer Strom durch die Erregerspule fließt, wodurch eine geringere Auslenkung des Kontaktmittel während des mechanischen Rüttelns an dem Kontaktmittel resultiert. Daher wird in einer weiteren Ausführungsform mittels mindestens eines Sensors eine Temperatur des elektromagnetischen Schalters gemessen. Vorteilhafterweise wird die Ansteuerung der Erregerspule des elektromagnetischen Schalters durch den Ansteuerkreis so lange verzögert, bis ein Wert der gemessenen Temperatur unter einen vorgebbaren Schwellenwert liegt.Heating during operation of the electromagnetic switch leads For example, an increasing resistance in the excitation coil, whereby a lower current flows through the exciting coil, whereby a smaller deflection of the contact means during the mechanical shaking results in the contact means. Therefore, in a further embodiment, a temperature of the electromagnetic switch is measured by means of at least one sensor. Advantageously, the activation of the excitation coil of the electromagnetic switch is delayed by the drive circuit until a value of the measured temperature is below a predefinable threshold value.
