Description
Das Patent 926732 betrifft eine Feldreglersteuerung für brennkraftelehtrischeTriebfahrz.euge, bei der die Erregung des Hauptgenerators mittels eines durch den Drehzahlregler der Antriebskraftmaschine :gesteuerten Schalters so beeinflußt wird, daß die Generatorbelastung mit steigender Drehzahl der Antriebskraftmasch.ine erhöht und mit sinkender Drehzahl verringert wird. Hierbei ist das Gestänge des Brennstoffventils (Reglergestänge) mit einem den elektrischen Verstellmotor des Feldwiderstandes des Hauptgenerators in der einen oder anderen Drehrichtung einschaltenden elektrischen Schalter gekuppelt und dieser Schalter spricht sowohl in Abhängigkeit von der eingestellten Drehzahl am Drehzahlsteller als auch von einem an diesem Schalter beliebig einstellbaren Drehmoment selbsttätig an. Gemäß dem Hauptpatent werden die Steuerbewegungen des Reglergestänges unmittelbar auf einen Stufenschalter übertragen, wobei die Stufeneinstellung selbst beliebig für ein gewähltes Drehmoment ahne Zuhilfenahme eines Schnellumschalters über die Kontaktsegmente auf den Umschaltmotor vorgenommen wird.The patent 926732 relates to a field regulator control for internal combustion engines, in which the excitation of the main generator by means of a through the speed controller the prime mover: controlled switch is influenced so that the generator load increases with increasing engine speed and with decreasing engine speed is decreased. The linkage of the fuel valve (regulator linkage) is with one of the electric adjusting motor of the field resistance of the main generator coupled electrical switch that turns on in one or the other direction of rotation and this switch speaks both as a function of the set speed on the speed controller as well as one that can be set as desired on this switch Torque on automatically. According to the main patent, the tax movements of the Transfer the control linkage directly to a step switch, with the step setting even arbitrarily for a selected torque without the aid of a quick switch is made via the contact segments on the changeover motor.
Die Erfindung verbessert diese Feldreglerstenerung dadurch, daß die Kontaktfinger bzw. Doppelkontaktfinger des Stufenschalters abhebbar ausgebildet sind.The invention improves this field regulator control in that the Contact fingers or double contact fingers of the tap changer are designed to be liftable are.
Die Erfindung sei nachfolgend an der einen Stufenschalter der FeldregJersteuerung gemäß dem Hauptpatent darstellenden Zeichnung beispielsweise näher erläutert.In the following, the invention is based on the one step switch of the field regulator control according to the drawing representing the main patent, for example, explained in more detail.
Si-Si , S2-,52, S3 S3', S4 S4 sind die Kontaktsegmente des Stufenschalters St. BI- Bi, B2-B2 , B3 B3' und B4 B4 sind die elektrisch miteinander verbundenenKontaktbürsten. DieKontaktsegmente S1 si , S2-S2/1 S3 S3 und S4-S4', die in der Umfangsrichtung verschiebbar angeordnet sind, bestehen aus den stromführenden Teilen a, die auf sämtlichen Stufendurch die Leiter l miteinander und über die Kontakteinrichtungen k mit je einem der beiden nicht dargestellten Schaltrelais für die Vor-oder Rückwärtsschaltung des Steuermotors verbunden sind. Die Kontaktsegmente Si s1 , S2 S2 usf. besitzen ferner einen isolierenden Teil b, der lediglich dazu dient, die Bürstengleitbahn nicht durch Lücken zu unterbrechen, was zur Beschädigung der stromzu- und -abführenden Gleitstücke führen würde.Si-Si, S2-, 52, S3 S3 ', S4 S4 are the contact segments of the St. BI-Bi, B2-B2, B3 B3' and B4 B4 are the electrically interconnected contact brushes. The contact segments S1 si, S2-S2 / 1 S3 S3 and S4-S4 ', which are arranged displaceably in the circumferential direction, consist of the current-carrying parts a, which are connected to each other on all stages through the conductors l and via the contact devices k with one of the two Switching relays, not shown, for the forward or reverse switching of the control motor are connected. The contact segments Si s1, S2, S2 etc. also have an insulating part b, which only serves to prevent the brush sliding path from being interrupted by gaps, which would damage the sliding pieces that supply and discharge current.
Gemäß der Erfindung sind nun die Kontaktbürsten Bi- Bi , B2-B2', B3-B 3 und B4 B4 als Kontaktfinger von den Kontaktsegmenten S.-S.", S2 S2 usf. ab'hebbar ausgebildet. Dann braucht nur jeweils der der am Fahrschalter eingestellten Drehzahlstufe entsprechende Kontaktfinger bzw. Doppelkontaktfinger auf seinem Kontaktsegment aufzuliegen, während die übrigen Kontaktfinger, beispielsweise durch Zugfedern, abgehoben sind. Dies hat gegenüber dauernd aufliegenden Kontaktfingern den Vorteil, daß die Reibungswiderstände am Stufenschalter St -,vesentlich geringer sind. Die :Auflegung des für die jeweilige Drehzahlstufe benötigten Kontaktfingers auf das zugehörige Kontaktsegment kann beispielsweise durch einen kleinen Elektromagneten bewirkt werden, der von der Leitung dieser Drehzahlstufe gespeist wird.According to the invention, the contact brushes Bi , B2-B2 ', B3-B 3 and B4-B4 are designed as contact fingers so that they can be lifted off the contact segments S.-S. ", S2, S2 etc. Then only the The corresponding contact fingers or double contact fingers set on the drive switch must rest on its contact segment, while the other contact fingers are lifted, for example by tension springs. This has the advantage over permanently resting contact fingers that the frictional resistances at the step switch St - are significantly lower the contact finger required for the respective speed level on the associated contact segment can be effected, for example, by a small electromagnet that is fed by the line of this speed level.
Die erfindungsgemäße Einrichtung hat den weiteren Vorteil, daß gewünschtenfalls die zur Vermeidung von Überströmen in den übrigen Drehzahlsteuerleitungen vorgesehenen Hilfsrelais H, R entfallen können, da durch das Abheben der nicht angesteuerten Kontaktfinger zwischen diesen Köntalctfingern und dem angesteuerten Kontaktfinger ,über die Kontaktsegmente keine leitende Verbbindung mehr besteht.The device according to the invention has the further advantage that, if desired those provided to avoid overcurrents in the other speed control lines Auxiliary relays H, R can be omitted, because by lifting the not activated Contact finger between these Köntalctfingern and the activated contact finger , there is no longer a conductive connection via the contact segments.
Durch die gemäß der Erfindung erzielbare weitgehende Verringerung der Reibungswiderstände am Stufenschalter wird die durch das Ankuppeln des Schalters an das Brennstoffregelgestänge eintretende zusätzliche Belastung des Drehzahlreglers entsprechend- verringert. Damit nehmen in gleichem Maße die Ansprechgenauigkeit des Drehzahlreglers und die Regelgenauigkeit des Servoreglers der Feldreglersteuerung zu.Due to the substantial reduction that can be achieved according to the invention the frictional resistance on the tap changer is caused by the coupling of the switch additional load on the speed controller occurring on the fuel control linkage correspondingly reduced. This increases the accuracy of the response to the same extent of the speed controller and the control accuracy of the servo controller of the field controller controller to.
