Description

Steuerungseinrichtung mit vom Leitungsstrom betätigtem Fahrschalter bei elektrischen Triebfahrzeugen. Bei elektrisch betriebenen Triebfahrzeugen pflegt man unmittelbar hinter dem Stromabnehmer einen Schalter mit Höchststrom-und Nullspannungsauslösu.ng einzubauen. Wird auch der Fahrschalter mit Leitungsstrom gesteuert, so steht im Falle der Aus= iösung ,des Hauptschalters für die Rückführung des Fahrschalters in die Nullstellung keine Kraftquelle zur Verfügung; der Fahrschalter bleibt also in der Stellung stehen, die er zufällig einnimmt, und kann erst nach Wiedereinschalten des Hauptschalters bewegt werden. Infolgedessen würde7beim Wiedereinschalten des Hauptschalters ein unzulässiger Stromstoß in den Triebmotoren auftreten, der unbedingt verhindert werden muß.Control device with drive switch operated by the line current in the case of electric traction vehicles. In the case of electrically operated locomotives Immediately behind the pantograph there is a switch with maximum current and zero voltage release to be built in. If the drive switch is also controlled with line current, the is displayed If the main switch is triggered for the return of the drive switch no power source available in the zero position; the drive switch remains stand in the position it happens to be in and can only be switched on again of the main switch. As a result, when the Main switch, an impermissible current surge in the traction motors, which is absolutely necessary must be prevented.

Um diesen Übelstand zu vermeiden, wird erfindungsgemäß ein weiterer Hauptschalter für die Triebmotoren vorgesehen, der mit Nullspannungsausschaltung versehen ist, also die Triebmotoren abschaltet, wenn der primäre Schalter ausgelöst worden ist. Wie bisher dient für die Rückführung des Fahrschalters bei Wiederauftreten der Spannung als Stromquelle das Leitungsnetz bzw. der Lokomotivtransformator, der aber gemäß der Erfindung die Bewegungsvorrichtung des Fahrschalters unmittelbar, also nicht über den Triebmotorenhauptschalter, speist. Dieser letztere muß mit dem Fahrschalter derart verriegelt sein, daß er nur in dessen Nullage wiedereingeschaltet werden kann.In order to avoid this inconvenience, according to the invention another Main switch provided for the traction motors, the one with zero voltage switch-off is provided, so turns off the traction motors when the primary switch is triggered has been. As before, it is used to return the drive switch when it occurs again the voltage as the power source, the line network or the locomotive transformer, the but according to the invention the movement device of the drive switch directly, so not via the main motor switch, feeds. This latter has to go with the The travel switch be locked in such a way that it is only switched on again in its zero position can be.

Die Wiedereinschaltung des Trieb@motorenhauptschalters kann auf rein mechanischem Wege oder elektromagnetisoh oder mit Hilfe von Druckluft vorgenommen werden. Dieser Schalter muß nicht immer als Ölschalter ausgebildet werden und kann bei Wechselstromfahrzeugen mit Leistungstransformator, in dessen Niederspannungskreis liegen. Die Wiedereinschaltung kann auch vom Fahrschalter aus bei dessen Rückkehr in die Nullstellung mittelbar oder unmittelbar selbsttätig bewirkt werden.The restart of the drive motor main switch can open mechanically or electromagnetically or with the help of compressed air will. This switch does not always have to and can be designed as an oil switch for AC vehicles with a power transformer, in its low-voltage circuit lie. It can also be switched on again from the drive switch when it returns can be automatically or indirectly brought into the zero position.

PATENT -ANSPRÜCHE: i. Steuerungseinrichtung mit vom Leitungsstrom betätigtem Fahrschalter bei elektrischen Triebfahrzeugen, dadurch gekennzeichnet, .daß. außer dem unmittelbar hinter -dem Stromabnehmer liegenden selbsttätigen Schalter noch ein besonderer Triebmotorenhauptschalter mit selbsttätiger Nullspannungsauslösung angebracht ist, welcher die Betätigungsvorrichtung des Fahrschalters nicht mit abschaltet und derart mit dem Fahrschalter verriegelt ist, daß er nur in dessen Nullstellung wiedereingeschaltet werden kann.. PATENT CLAIMS: i. Control device with a drive switch actuated by the line current in electric traction vehicles, characterized in that. In addition to the automatic switch located directly behind the pantograph, there is also a special main motor switch with automatic zero voltage release, which does not switch off the actuator of the travel switch and is locked to the travel switch in such a way that it can only be switched on again in its zero position. 2. Einrichtung nach Anspruch i, gekennzeichnet durch eine Vorrichtung, welche die Wiedereinschaltung .des Triebmotorenhauptschalters vom Fahrschalter aus bei dessen Rückkehr in die Nullstellung selbsttätig bewirkt.2. Device according to claim i, characterized by means of a device that switches on the traction motor main switch again caused automatically by the travel switch when it returns to the zero position.
