Description
Verfahren zum Anlassen von doppelt gespeisten Drehstrommotoren mit Hilfe einer besonderen Anlaßmaschine Es ist bekannt, doppelt gespeiste Drehstrommotoren mit Hilfe einer besonderen Anlaßmaschine anzulassen, die während des Anlaßvorganges Ströme steigender Frequenz liefert und nach dem Anfahren des .anzulassenden Motors abgeschaltet wird, während der angelassene Motor an das Netz angeschaltet wird.Procedure for starting double-fed three-phase motors with Using a special starting machine It is known to use double-fed three-phase motors to start with the help of a special starting machine, which occurs during the starting process Supplies currents of increasing frequency and after starting up the motor to be approved is switched off while the started engine is connected to the mains.
Als Anlaßmaschine kann entweder ein aus Antriebsmotor und Generator bestehendes Aggregat verwendet werden oder ein Schleifringmotor, der zunächst auf die synchrone Drehzahl gebracht . und hierauf abgebremst wird, so daß, in diesem Falle ebenfalls Ströme steigender Frequenz für den Anlaßvorgang des Doppelfeldmotors zur Verfügung stehen.Either a drive motor and a generator can be used as the starting machine existing unit can be used or a slip ring motor, which is initially based on brought the synchronous speed. and is then braked so that, in this Also trap currents of increasing frequency for the starting process of the double field motor be available.
Man hat bisher bei solchen Anlaßanordnungen den anzulassenden Motor ständerseitig an das Netz angeschlossen und benötigte dann für die zweite Wicklung einen Anlaßwiderstand, der vor dem Umschalten auf das Anlaßaggregat abgeschaltet werden mußte. Der Schaltvorgang wird durch diese Anordnung in mehrere Teilschritte zerlegt, deren Reihenfolge genau eingehalten werden muß, um Störungen zu vermeiden.So far, one has the engine to be started with such starting arrangements Connected to the mains on the stator side and then required for the second winding a starting resistor, which is switched off before switching to the starting unit had to become. With this arrangement, the switching process is divided into several sub-steps disassembled, the order of which must be strictly adhered to in order to avoid malfunctions.
Aufgabe der Erfindung ist es, den Anlaß; vorgang für doppelt gespeiste DrehstroM-motoren zu vereinfachen. Dies geschieht gemäß -der Erfindung dadurch, daß Ständer und Läufer des anzulassenden Motors während des Anlaßvorganges in Parallel- oder Hintereinanderschaltung an die Anlaß,-maschine angeschaltet werden. Einige Schaltbilder für Anordnungen gemäß der Erfindung sind in den Abb. i bis' q. dargestellt. Bei den Schaltungen nach den Abb. i. und 3 dient zum Anlassen des Doppelfeldmotors.'M ein besonderes Anlaßaggnegat, bestehend aus einer Hilfsantriebsmaschine H und einem mit dieser gekuppelten Generator A. Bei den Schaltungen nach den Abb. 2 und q. wird ein Doppelfeldmotor M mit Hilfe eines Schleifringmotors; A angelassen, der zunächst hochgefahren und dann abgebremst wird und dessen Läufer beim Abbremsen Ströme steigender Frequenz liefert.The object of the invention is to provide the occasion; operation for double fed To simplify three-phase motors. According to the invention, this is done by that the stator and rotor of the engine to be started in parallel during the starting process or series connection to the starter machine. Some Circuit diagrams for arrangements according to the invention are shown in Figs. I to 'q. shown. With the circuits according to Fig. I. and 3 is used to start the double field motor.'M a special starting unit, consisting of an auxiliary drive machine H and a with this coupled generator A. In the circuits according to Fig. 2 and q. will a double field motor M with the aid of a slip ring motor; A tempered that initially is ramped up and then braked and its rotor currents rise when braking Frequency supplies.
Die Schaltungen nach den Abb. i und 2 zeigen die Parallelschaltung von Ständer- und Läuferwicklung des Doppelfeldmotors M während des Anlaßvorganges, während bei den Schaltungen nach den Abb. 3 und ¢ Ständer und Läufer des Motors !Y1 h5ntereinandergeschaltet sind.The circuits according to Figs. I and 2 show the parallel connection of the stator and rotor windings of the double field motor M during the starting process, while with the circuits according to Fig. 3 and ¢ stator and rotor of the motor ! Y1 are connected in series.
In allen Fällen werden nach Durchführung des Anlaßvorganges Ständer und Läufer des Motorsl ;M. an das Netz N angeschaltet.In all cases, the stator and rotor of the motor ; M. connected to the network N.
