Description
Einrichtung zur Anzeige des Schleuderns von in Reihe geschalteten, nicht miteinander gekuppelten elektrischen Triebmotoren Bei in Reibe geschalteten, nicht miteinander gekuppelten elektrischen Triebmotoren ist stets die Gefahr vorhanden, daß einer oder mehrere Motoren zum Schleudern kommen. Es genügt meistens, daß der Führer auf diese Gefahr aufmerksam gemacht wird. Es ist ein Verfahren bekannt geworden, bei dem zur Einleitung von Vorgängen, die das Schleudern derartiger Motoren verhüten sollen, die Bürstenspannungen der einzelnen Triebmotoren miteinander verglichen «-erden. Hierfür waren bis jetzt so viele Anzeigevorrichtungen nötig, als Triebmotoren zu beobachten waren, wodurch die Übersicht sehr erschwert war.Device for displaying the spinning of series-connected, Electric traction motors that are not coupled to one another. Electric traction motors that are not coupled to one another always run the risk of that one or more motors spin. It is usually enough that the Leaders are made aware of this danger. A procedure has become known in the case of initiating processes that prevent such motors from spinning should compare the brush voltages of the individual traction motors "-earth. Up until now, this required as many display devices as the drive motors could be observed, which made the overview very difficult.
Nach .der Erfindung erfolgt ein Vergleich der Bürstenspannungen mittels einer Einrichtung, welche zu einem Instrument vereinigte Spannungsmesser mit je einem Zeiger für den Motor aufweist. Bei gleichmäßiger Verteilung der Betriebsspannung stehen alle Zeiger hintereinander, d.'h. sie decken sich, so daß sämtliche Zeiger bei jeder beliebigen, aber für alle Motoren unter sich gleichen Spannung nur als ein einziger Zeiger in Erscheinung treten. Kommt dagegen ein Motor zum Schleudern, wodurch seine Spannung von derjenigen der übrigen Motoren wesentlich verschieden wird, so tritt der diesem Motor entsprechende Zeiger aus der überdeckung der übrigen Zeiger heraus.According to the invention, the brush voltages are compared by means of a device which unified to one instrument voltmeter with each has a pointer for the engine. With an even distribution of the operating voltage all pointers are one behind the other, i.e. they coincide so that all pointers at any voltage, but for all motors under the same voltage, only as a single pointer appear. If, on the other hand, a motor starts to spin, which makes its voltage significantly different from that of the other motors then the pointer corresponding to this motor emerges from the overlap of the others Pointer out.
Ein Ausführungsbeispiel für eine Einrichtung gemäß der-Erfindung ist in Fig. r der Zeichnung schematisch dargestellt unter eglassung aller für die vorliegende Erfindung unwesentlichen Teile. In der Figur bedeuten r, 2, 3, q. Zeiger von nicht gezeichneten Spannungsmessern. Die Drehachsen 5 der Zeiger t ... 4. sind ineinandergeschaltet; sie könnten auch hintereinander in einer Linie liegen.An embodiment of a device according to the invention is in Fig. R of the drawing shown schematically, including all for the present Invention insignificant parts. In the figure, r, 2, 3, q mean. Pointer of not drawn tension meters. The axes of rotation 5 of the pointer t ... 4. are interconnected; they could also be in a line one behind the other.
Wie Fig. 2 beispielsweise andeutet, kann mit einem Zeiger (in der Figur Zeiger r) ein Kontaktbügel 6 verbunden sein, der bei einer Abweichung von der gleichmäßigen Verteilung der Betriebsspannung mit den aus der Reihe austretenden Zeigern in Kontaktberührung kommt, wodurch z. B. die Abschaltung eines Schalters oder eine Signalgebung bewirkt werden kann. Durch diesen Bügel 6 wird erreicht, daß eine Kontaktberührung innerhalb «-eiter Grenzen der Motorspannung nicht erfolgt, wenn die einzelnen Motoren praktisch unter gleicher Spannung stehen, während eine solche Berührung bereits bei verhältnismäßig kleiner Differenz zwischen den Spannungen der einzelnen Motoren eintritt und z. B. die Abschaltung des Schalters bewirkt.- ------- -Die Zugehörigkeit der Zeiger zu den Motoren kann durch verschiedenartige Färbung oder verschiedenartige Formgebung der Zeiger kenntlich gemacht sein. Es kann auch der oberste Zeiger z. B. schwarz und alle übrigen rot bemalt sein, wobei dann jeweils die Erscheinung der roten Zeiger das Eintretendes Schleuderns anzeigt.As FIG. 2 indicates, for example, a contact bracket 6 can be connected to a pointer (pointer r in the figure) which, if there is a deviation from the uniform distribution of the operating voltage, comes into contact with the pointers emerging from the series, whereby z. B. the disconnection of a switch or a signaling can be effected. With this bracket 6 it is achieved that a contact within «-eiter limits of the motor voltage does not occur if the individual motors are practically under the same voltage, while such contact occurs with a relatively small difference between the voltages of the individual motors and z. B. causes the switch to switch off. ------- -The affiliation of the pointers to the motors can be identified by different colors or different shapes of the pointers. It can also be the top pointer z. B. painted black and all the rest of the red, the appearance of the red pointer then indicates the occurrence of skidding.
