Description
Einrichtung zum vorübergehenden Schlüpfenlassen eines einzelnen Synchrongenerators Gegenstand der Hauptpatentanmeldung ist eine Einrichtung zum vorübergehenden Schlüpfenlassen eines einzelnen, insbesondere über eine Erregermaschine erregten Synchronmotors durch vorübergehende Schwächung des Motorerregerfeldes durch Einschalten eines Widerstandes. Der Gegenstand der Hauptpatentanmeldung unterscheidet sich von dem Bekannten dadurch, daß ein von dem im Erregerfeldkreis des Motors induzierten Wechselstrom abhängiges Schrittschaltwerk - dessen einzelnen Schaltschritten jeweils ein Schlupf über eine doppelte Polteilung entspricht - in Verbindung mit einem Einstellorgan zur selbsttätigen Beendigung der Schwächung des Motorerregerfeldes nach Erreichen eines durch die Einstellung am Einstellorgan bestimmten Schlupfes vorgesehen ist und daß mit Abschaltmitteln des Motors ein die Frequenz des Schlupfwechselstromes erfassender Meßfühler derart in Auslöseverbindung steht, daß er die Abschaltung des Motors bei Überschreiten eines bestimmten Wertes der Frequenz des Schlupfwechselstromes selbsttätig auslöst.Device for temporarily allowing a single synchronous generator to slip The subject of the main patent application is a device for temporary hatching a single synchronous motor, in particular excited by an exciter by temporarily weakening the motor excitation field by switching on a resistor. The subject of the main patent application differs from the known in that that a dependent on the alternating current induced in the excitation field circuit of the motor Stepping mechanism - whose individual switching steps each slip over a double pole pitch corresponds - in connection with an adjusting element for automatic End of the weakening of the motor excitation field after reaching one by the Adjustment is provided on the adjusting element and that with shutdown means of the motor, a measuring sensor which detects the frequency of the alternating slip current in this way is in trigger connection that he switches off the engine when exceeded a certain value of the frequency of the alternating slip current is triggered automatically.
Es wird damit die Aufgabe gelöst, jeden einzelnen Synchronmotor unabhängig von anderen Synchronmotoren für sich allein selbsttätig vorübergehend um einen bestimmten einstellbaren Wert schlüpfen zu lassen. Dies ist insbesondere beim Antrieb von Arbeitsmaschinen mit schwingenden Massen wichtig, um Schäden am Fundament, umgebenden Gebäuden od. dgl. verursachende mechanische Resonanzlagen mit einer oder mehreren benachbarten Arbeitsmaschinen zu vermeiden.This solves the problem of making each individual synchronous motor independent from other synchronous motors by itself temporarily by a certain one adjustable value to slip. This is especially true when driving machines with vibrating masses important to avoid damage to the foundation, surrounding buildings or the like. Like. Causing mechanical resonance positions with one or more neighboring ones Avoid working machines.
Nach der Erfindung läßt sich die Einrichtung nach der Hauptpatentanmeldung auch zum vorübergehenden Schlüpfenlassen eines einzelnen Synchrongenerators verwenden, wobei an Stelle des Motorerregerfeldes das Generatorerregerfeld entsprechend beeinflußt wird.According to the invention, the device can be according to the main patent application can also be used to temporarily let a single synchronous generator slip, whereby instead of the motor excitation field, the generator excitation field influences accordingly will.
Die selbsttätige Einsteuerung eines Synchrongenerators in eine vorgegebene relative Polradlage unter Vermeidung von Nachteilen und Schäden ist insbesondere bei durch Kolbenmaschinen angetriebenen Synchrongeneratoren vorteilhaft, beispielsweise bei durch Gasmotoren angetriebenen Generatoren in Hochofenanlagen. Solche die im Hochofenprozeß abfallenden Gichtgase als Brennstoff verwendenden Motoren haben nämlich erhebliche schwingende Massen.The automatic control of a synchronous generator in a given relative pole wheel position while avoiding disadvantages and damage is particular advantageous for synchronous generators driven by piston engines, for example in the case of generators driven by gas engines in blast furnace systems. Those in the Blast furnace process waste furnace gases as fuel using engines namely considerable vibrating masses.
Durch die erfindungsgemäße Verwendung der Einrichtung nach der Hauptpatentanmeldung werden gegenüber den bekanntgewordenen Einsteuerverfahren und -einrichtungen für Synchronmaschinen die gleichen Vorteile wie beim Gegenstand der Hauptpatentanmeldung erzielt, nämlich das selbsttätige vorübergehende Schlüpfenlassen eine Synchrongenerators uin einen bestimmten einstellbaren Wert und das selbsttätige Abschalten des Generators bei Überschreiten eines bestimmten Schlupfes unabhängig von etwaigen weiteren Synchrongeneratoren.By using the device according to the invention according to the main patent application are compared to the known control procedures and facilities for Synchronous machines have the same advantages as with the subject of the main patent application achieved, namely the automatic temporary hatching of a synchronous generator uin a certain adjustable value and the automatic shutdown of the generator if a certain slip is exceeded, independent of any other synchronous generators.
Mit den bekanntgewordenen Einsteuerverfahren und -einrichtungen können nur zwei oder mehrere Synchronmaschinen in Abhängigkeit voneinander verstellt werden.With the control procedures and devices that have become known, you can only two or more synchronous machines can be adjusted depending on each other.
