Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen in Verbindung mit dem nachstehend beschriebenen und in der Zeichnung in einem Schaltbild wiedergegebenen Ausführungsbeispiel einer erfindungsgemäßen überwachungseinrichtung.possible errors of the alternator can be achieved can. To solve this problem, the measures specified in the characterizing part of claim 1 are provided. Further refinements of the invention emerge from the subclaims in connection with what follows described and shown in the drawing in a circuit diagram embodiment of an inventive monitoring device.

In der Zeichnung sind die drei Drehstromwicklungen eines dreiphasigen, im einzelnen nicht näher bezeichneten Drehstromgenerators bei 11, 12 und 13 angedeutet. Die drei Drehstromwicklungen sind in einem Sternpunkt 1k zusammengefaßt, ihre freien Wicklungsenden sind mit u, τ und w bezeichnet. An jede Drehstromwicklung ist eine von drei Erregerstromdioden 16, 17 und 18 angeschlossen, die an einen gemeinsamen Anschlußpunkt D + für eine Erregerwicklung 20 angeschlossen sind, die ein gegenüber den feststehenden Drehstromwicklungen 11, 12 und 13 umlaufendes Gleich-Magnetfeld erzeugt, wenn sie von einem getakteten, über einen Leistungstransistor 21 eines im übrigen nicht näher dargestellten Spannungsreglers R geführten Erregerstrom durchflossen wird.In the drawing, the three three-phase windings of a three-phase three-phase generator, not specifically designated in detail, are indicated at 11, 12 and 13. The three three-phase windings are combined in a star point 1 k , their free winding ends are labeled u, τ and w. One of three excitation current diodes 16, 17 and 18 is connected to each three-phase winding, which are connected to a common connection point D + for an excitation winding 20, which generates a direct magnetic field rotating with respect to the stationary three-phase windings 11, 12 and 13 when it is triggered by a clocked excitation current carried through a power transistor 21 of a voltage regulator R (not shown in detail).

An die Drehstromwicklungen 11, 12 und 13 ist je eines von drei Laststrom-Gleichrichterpaaren 22, 23 bzw. 2k, 25 bzw. 26, 27 angeschlossen, die über eine gemeinsame Minusleitung 28 an den Minuspol einer Sammlerbatterie SB und über eine gemeinsame Plusleitung 29 an den Pluspol dieser Batterie geführt sind. Außerdem ist ein Zündschalter 31 vorgesehen, der über eine Klemme 15 ein Anzeigeelement 32, beispielsweise eine Kontrollampe zur Wirkung bringt, wenn der Zuschalter 31 geschlossen wird, jedoch der Generator im Stillstand oder bei zu niedrigen Drehzahlen noch keine ausreichend hohe, One of three load current rectifier pairs 22, 23 or 2k, 25 or 26, 27 is connected to each of the three-phase windings 11, 12 and 13 the positive pole of this battery are carried out. In addition, an ignition switch 31 is provided, which brings a display element 32, for example a control lamp, into effect via a terminal 15 when the switch 31 is closed, but the generator is not yet sufficiently high at standstill or at too low speeds.

The lamp 32 goes out when the generator "as intended provides sufficient charging voltage for the battery.

Zur Überwachung des ordnungsgemäßen Betriebsverhaltens des Generators ist eine Überwachungseinrichtung 35 vorgesehen, an welche das Anzeigeelement 32 angeschlossen ist und dann aufleuchtet, wenn ein Fehler aufgetreten ist. Um diese Überwachung möglichst umfassend in ihrer Aussage zu machen, sind sämtliche drei Phasenspannungen des Generators, nämlich die zwischen den Wicklungsenden u und ν liegende Phasenspannung ü , die zweite Phasenspannung U zwischen den Wicklungsenden ν und w und vwTo monitor the correct operating behavior of the generator, a monitoring device 35 is provided, to which the display element 32 is connected and then lights up when an error has occurred. In order to make this monitoring as comprehensively as possible in their statement, all three phase voltages of the generator, namely, the u between the coil ends and opposite phase voltage ν u, ν the second phase voltage U between the winding ends and w and vw

Dort werden diese drei Phasenwicklungen daraufhin überwacht, ob sie untereinander nach Betrag und Phase gleich groß sind, d.h. jeweils mit 120 gegeneinander versetzt gleiche Spitzenwerte aufweisen. Wenn einer dieser Spitzenwerte mit den anderen beiden nicht übereinstimmt, ist eine sichere Aussage dafür gegeben, daß ein Fehler in im dargestellten Bordnetz bzw.. im Generator vorliegt.w and u are fed to the evaluation circuit 35. There will be these three phase windings are monitored to determine whether they are equal to each other in terms of magnitude and phase, i.e. each with 120 offset from one another have the same peak values. If any of these peaks with the the other two do not match, a reliable statement is given that there is an error in im On-board network or in the generator is present.
