KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Betrieb elektrischer Vollbahnen erfordert Motorwagen mit mehreren Motoren, um in kurzer Zeit eine bestimmte , Geschwindigkeit erreichen zu können. Die Motoren haben daher beim Anziehen eine grofse Arbeitsleistung abzugeben, während bei voller Fahrt oder bei fallendem Gelände die erforderliche Leistung und daher auch der Stromverbrauch der Motoren wieder sinkt. Um nun einen möglichst hohen Nutzeffect zu erhalten und um die Leerlau farbeit einzelner Motoren zu sparen, ist es vortheilhaft, diese geringe Leistung auch von einer kleineren Anzahl von Motoren zu bekommen. Es müssen demnach .Motoren ausgeschaltet werden, wenn der Strömverbrauch entsprechend gesunken ist. Andererseits" ist es bei ansFeige'ndefn' Gelände" erforderlich, Motoren wieder zuzuschalten^ da sonsrdIe"wern§en_D5in arbeTtenden Motoren überlastet würden. Schliefs-IicH~""müssen alle: Motoren.. gegen...Ueberlastung geschützt sein durch einen Maximalausschalter, der gegebenfalls alle Motoren ausschaltet und der nur von Hand einzurücken wäre.The operation of full electric railways requires motor vehicles with several motors in order to be able to reach a certain speed in a short time. The motors therefore have to deliver a great deal of work when they are tightened, while at full speed or on sloping terrain the required power and therefore also the power consumption of the motors decreases again. In order to obtain the highest possible efficiency and to save the idling work of individual engines, it is advantageous to get this low power from a smaller number of engines. Accordingly, motors must be switched off when the current consumption has decreased accordingly. On the other hand, "it is necessary when there is a new terrain" to switch on motors again ^ since other "wern§ en _D5i n working motors would be overloaded. Closing-IicH ~""must all: motors .. protected against ... overload be through a maximum off switch, which switches off all motors if necessary and which would only have to be engaged by hand.
Vorliegende Erfindung bezweckt nun, unabhängig vom Wagenführer durch eine selbstthätige Schaltvorrichtung einen möglichst geringen Stromverbrauch ~zu',erzielen, und., zwar, durch rechtzeitiges Ausschalten von Motoren. The present invention aims to achieve the lowest possible power consumption , independently of the driver, by means of an automatic switching device, namely by switching off motors in good time.
"Wie aus dem in Fig. 2 dargestellten Schaltnngsschema ersichtlich ist, sind zwei Gruppen a und b von Motoren angenommen, und jede Gruppe besteht beispielsweise aus zwei Motoren, welche im gemeinsamen Stromkreis parallel geschaltet sind. Der Maximalausschalter (Magnetspule c) liegt zwischen dem Generator und den Motoren und Motorgruppen."As can be seen from the circuit diagram shown in FIG. 2, two groups a and b of motors are assumed, and each group consists, for example, of two motors which are connected in parallel in the common circuit. The maximum cut-out switch (magnetic coil c) is located between the generator and the engines and engine groups.
Die Wirkungsweise ist folgende:
Spule d ist so eingerichtet, dafs der Eisenkern e bei normalem Stromverbrauch der Motoren
b der Feder f das Gleichgewicht hält. Der Doppelhebel g, der im Punkte h drehbar
ist, trägt an dem einen Hebelarm den Eisenkern e, an dem anderen die Federy. Beide
sind einstellbar für bestimmte Stromstärken. Fest mit dem Doppelhebel g ist der Ansatz i
verbunden, der eine gerade Fläche trägt. Diese Fläche legt sich gegen die Feder k und dämpft
die Schwankungen, die durch das Anziehen des Eisenkernes e bei Stromstöfsen hervorgerufen
werden, auch bieten diese Fläche und die Feder f die Möglichkeit, die Stromdifferenz
zwischen dem Ausschalten und Zuschalten der zweiten Motorgruppe b einstellen zu können.
Erst wenn der Stromverbrauch ein Minimum erreicht hat, übersteigt die Spannkraft der
Feder _/ die Anziehungskraft der Spule d und die Reibung der Fläche i gegen die Feder k,
der Ansatz / drückt auf den Hebel m und löst den Winkelhebel η aus. Die gespannte Feder 0
kommt jetzt zur Wirkung und löst den Contact bei p, schaltet somit die zweite Gruppe b
aus und Gruppe α hat somit die ganze Leistung abzugeben. Die Spule c liegt ferner im Stromkreis
der Motorgruppe α und ist so eingerichtet, dafs der Eisenkern q angezogen wird,
sobald die Belastung der Motorgruppe α ein Maximum erreicht hat. Durch diese Bewegung
des Eisenkernes q wird ein Hebel r mitgenommen, durch welchen unter Vermittelung
von Druckluft oder Druckwasser und Kolben s, der Zahnstange t und des Zahnrades u der Contact
bei ρ wieder geschlossen wird. Die Motor-The mode of action is as follows:
Coil d is arranged in such a way that the iron core e maintains the equilibrium of the spring f with normal current consumption of the motors b. The double lever g, which can be rotated at point h , carries the iron core e on one lever arm and the springy on the other. Both are adjustable for certain currents. The approach i , which carries a straight surface, is firmly connected to the double lever g. This surface lies against the spring k and dampens the fluctuations that are caused by the attraction of the iron core e in the event of current surges; this surface and the spring f also offer the possibility of being able to adjust the current difference between switching off and switching on the second motor group b . Only when the power consumption has reached a minimum does the tension of the spring _ / exceed the attractive force of the coil d and the friction of the surface i against the spring k, the attachment / presses on the lever m and triggers the angle lever η . The tensioned spring 0 now comes into effect and releases the contact at p, thus switching off the second group b and group α therefore has to deliver all the power. The coil c is also in the circuit of the motor group α and is set up in such a way that the iron core q is attracted as soon as the load on the motor group α has reached a maximum. Through this movement of the iron core q , a lever r is carried along, through which the contact at ρ is closed again by means of compressed air or pressurized water and piston s, the rack t and the gear u. The motor
gruppe b bekommt jetzt wieder Strom, und die Arbeit wird wieder durch alle Motoren gemeinsam geleistet.group b is now getting electricity again, and all the motors do the work together again.
Der gleiche Zweck lä'fst sich mittelst Prefsluft, Druckwasser, eines Hülfsmotors oder dergl. erreichen. Sobald bei ρ der Contact geschlossen wurde, hat die Motorgruppe b wieder Strom und Spule d zieht den Hebel g wieder in die waagrechte Lage bezw. Anfangslage zurück.The same purpose can be achieved by means of pressurized air, pressurized water, an auxiliary motor or the like. As soon as the contact has been closed at ρ , the motor group b has current again and coil d pulls the lever g back into the horizontal position or. Starting position back.
