Bei der durch D. R. P. 147680 geschützten Zugsteuerungseinrichtung werden die Motorstromkreise durch Ruhestrommagnete überwacht, und beim Ziehen der Notbremse wird durch einen mit dem Notbremshahn mechanisch gekuppelten Schalter der Ruhestrom unterbrochen. Die Zuführung des letzteren zu der Leitung b, an welche die Wicklungen der Ruhestrommagnete angeschlossen sind, geschieht dabei durch eine den Zug entlang geführte Leitung über einen Kurzschlußbügel am Ende des Zuges.In the train control device protected by DRP 147680, the motor circuits are monitored by closed-circuit magnets, and when the emergency brake is pulled, the closed-circuit current is interrupted by a switch mechanically coupled to the emergency brake valve. The latter is fed to the line b, to which the windings of the closed-circuit magnets are connected, by means of a line guided along the train via a short-circuit clip at the end of the train.
Diese Leitung und das lästige Einlegen des Kurzschlußbügels kann nun gemäß vorliegender Erfindung gespart werden, indem die Wicklung der Ruhestrommagnete nicht durch Stromunterbrechung, sondern durch Kurzschließen stromlos gemacht wird. Es empfiehlt sich dabei in die Stromzuführung zu der Leitung b einen Widerstand, eine Schmelzsicherung oder dergl. einzuschalten, um das Anwachsen der Energiemengen beim Kurzschließen der Ruhestromwicklung auf ein gewisses Maß zu beschränken.According to the present invention, this line and the annoying insertion of the short-circuit clip can now be saved in that the winding of the closed-circuit magnets is not de-energized by interrupting the current, but rather by short-circuiting. It is advisable to switch on a resistor, a fuse or the like in the power supply to the line b , in order to limit the increase in the amount of energy when the closed-circuit winding is short-circuited.
In der Zeichnung ist eine Ausführungsform der Erfindung für einen Dreiwagenzug dargestellt. The drawing shows an embodiment of the invention for a three-car train.
b ist die den Zug entlang geführte elektrische Leitung, die über die Vorschaltwiderstände η aus der Oberleitung mit Strom gespeist wird. Zwischen Leitung b und Erde liegen die Wicklungen h der Ruhestrommagnete 2, welche im erregten Zustande entgegen der Wirkung der Federn I ihre Anker k anziehen. Letztere tragen die Kontaktbrücken m für den Motorenstrom. e sind die Notschalter, deren bewegliche Stromschlußstücke/ mit den Notbremshähnen g mechanisch verbunden sind. Die festen Stromschlußstücke ο und ρ sind an Leitung b bezw. an Erde angeschlossen. b is the electrical line running along the train, which is fed with electricity from the overhead contact line via the series resistors η. The windings h of the closed-circuit magnets 2 are located between line b and earth, which, when excited, attract their armature k against the action of the springs I. The latter carry the contact bridges m for the motor current. e are the emergency switches, the movable current connection pieces of which / are mechanically connected to the emergency brake cocks g. The fixed current connectors ο and ρ are respectively on line b. connected to earth.
Die Wirkungsweise ist folgende:
Steht die Leitung b unter Spannung, so fließt durch jede Wicklung h ein Ruhestrom
zur Erde. Sämtliche Magnete i haben ihre Anker k angezogen und die Motorenstromkreise
sind durch die Kontaktbrücken m geschlossen. The mode of action is as follows:
If line b is live , a quiescent current flows through each winding h to earth. All magnets i have attracted their armature k and the motor circuits are closed by the contact bridges m .
Stellt während der Fahrt ein Reisender durch Drehen eines Notbremshahnes g die Bremse an, so werden zugleich durch das bewegliche Stromschlußstück f die festen Stromschlußstücke'0 _p miteinander und damit Leitung b unmittelbar mit Erde verbunden. Die Wicklungen h werden stromlos, die Fedem / ziehen die Anker k von den Magneten i ab und unterbrechen durch Abheben der Kontaktbrücken m die Motorenstromkreise.If, while driving, a traveler turns on the brake by turning an emergency brake valve g , the movable current connection piece f simultaneously connects the fixed current connection pieces'0_p to one another and thus line b directly to earth. The windings h are de-energized, the springs / pull the armature k from the magnets i and interrupt the motor circuits by lifting the contact bridges m.
