Description
Die Erfindung betrifft eine Schaltung elektrischer, mit Drehstrom betriebener ■Weichenantriebe, bei der der Motor bei Erreichung der Endlagen der Weiche nur im Stellwerk vom Netz abgeschaltet wird.The invention relates to a circuit of electrical, three-phase operated ■ point drives, in which the motor is only in the signal box when the end positions of the switch are reached is disconnected from the grid.
Eine derartige Schaltung wird nach der Erfindung dadurch verbessert, daß zur Ersparnis einer Kabelader für die Zuleitung des Überwachungsstromes zum Antrieb zwei Stellleitungen im Stellwerk, die dritte Stelleitung aber im Antrieb abgeschaltet werden und der Überwachungsstrom dieser Leitung im Antrieb vor dem Schalter entnommen wird, der durch ein Relais in der einen Stelleitung gesteuert wird.Such a circuit is improved according to the invention in that to save a cable core for the supply of the monitoring current to the drive two control lines in the signal box, but the third control line in the drive can be switched off and the Monitoring current is taken from this line in the drive before the switch, the is controlled by a relay in one control line.
Erfindungsgemäß werden die im Stellwerk abschaltbaren Stelleitungen in an sich bekannter Weise im abgeschalteten Zustand kurzgeschlossen und geerdet. Auch die jeweils nicht benutzte Überwachungsleitung wird, wie bei Gleichstromantrieben bekannt, im Antrieb geerdet.According to the invention, the control lines that can be switched off in the signal box are known per se Way, when switched off, short-circuited and grounded. Also each Monitoring cables that are not used are earthed in the drive, as is known with direct current drives.
Auf der Zeichnung ist ein Ausführungsbeispiel einer Schaltung nach der Erfindung dargestellt.In the drawing is an embodiment of a circuit according to the invention shown.
i, 2 und 3 sind die vom Drehstromnetz kommenden Zuleitungen. Zwei dieser Zuleitungen sind im Antrieb mit dem Motor dauernd verbunden. In die dritte Leitung 1 ist im Antrieb ein Schalter m eingebaut, der durch ein Relais R in einer der beiden anderen Leitungen, auf der Zeichnung der Leitung 2, gesteuert wird. Die gekuppelten Umschalter g und h schalten in üblicher Weise die Drehrichtung um, und der wiederum gekuppelte Umschalter i legt je eine der Überwachungsleitungen 4 oder 5 an den Überwachungsmagneten Ü. Die Schalter g, h und i werden gleichzeitig von Hand betätigt. Dabei werden die gekuppelten Ausschalter k und Z (Springschalter) jedesmal geschlossen.i, 2 and 3 are the supply lines coming from the three-phase network. Two of these supply lines are permanently connected to the motor in the drive. In the third line 1, a switch m is installed in the drive, which is controlled by a relay R in one of the other two lines, on the line 2 drawing. The coupled changeover switches g and h switch the direction of rotation in the usual way, and the coupled changeover switch i each places one of the monitoring lines 4 or 5 on the monitoring magnet Ü. The switches g, h and i are operated manually at the same time. The coupled off switches k and Z (spring switch) are closed each time.
Die Überwachungsleitung 6 ist im Antrieb von der Stelleitung 1 vor dem Schalter m abgezweigt. The monitoring line 6 is branched off from the control line 1 in front of the switch m in the drive.
Hat der Weichenantrieb die neue Endlage erreicht, so haben alle Schalter α bis d ihre Lage gewechselt. Es fließt dann ein Überwachungsstrom durch Leitung 6, c, d, 5, i, Ü, Erde oder in der anderen Weichenlage 6 ,a,b, 4, i, Ü, Erde. Der Überwachungsmagnet wirft den Springschalter k, I heraus, wodurch der Motor abgeschaltet wird.When the point machine has reached the new end position, all switches α to d have changed their position. A monitoring current then flows through line 6, c, d, 5, i, Ü, earth or in the other switch layer 6, a, b, 4, i, Ü, earth. The monitoring magnet throws the switch k, I out, which switches off the motor.
Die jeweilig nicht benutzte Überwachungsleitung 4 oder 5 wird durch die Erdungsschalter / bzw. e an Erde gelegt. Während der Weichenbewegung sind beide Leitungen 4 und s geerdet. Schalter e wechselt gleichzeitig mit α und c und Schalter / gleichzeitig mit b und d seine Lage.The respective unused monitoring line 4 or 5 is connected to earth by the earthing switch / or e. Both lines 4 and s are earthed during the switch movement. Switch e changes its position simultaneously with α and c and switch / simultaneously with b and d.
Beim jedesmaligen Arbeiten des Springschalters /, k, I werden nicht nur die Leitungen 2, 3 vom Netz getrennt, sondern gleichzeitig noch unter sich kurzgeschlossen und an Erde gelegt, wie aus der ZeichnungEach time the switch /, k, I is operated, not only are the lines 2, 3 disconnected from the mains, but also short-circuited among themselves and connected to earth at the same time, as shown in the drawing
ersichtlich ist. Hierdurch werden Fremdströme abgeleitet und die Sicherungen der Leitungen aus denen sie stammen, zum Schmelzen gebracht.can be seen. In this way, external currents are diverted and the fuses of the Lines from which they originate melted.
Wird im Stellwerk der Weichenschalter umgelegt, so fließt zunächst Strom nur durch die Leitungen 2 und 3. Das Relais R zieht aber seinen Anker an und schließt den Kontakt/n und damit die Leitung 1. Nunmehr läuft der Motor m an. Nach Abschaltung des Motors durch den Schalter k, I wird das Relais R stromlos, und der Schalter m öffnet sich wieder. Da dies im stromlosen Zustand erfolgt, ist eine Wartung des Kontaktes m kaum erforderlich.If the switch is thrown in the signal box, current initially only flows through lines 2 and 3. The relay R pulls in its armature and closes the contact (s) and thus line 1. The motor m starts up. After the motor has been switched off by the switch k, I , the relay R is de-energized and the switch m opens again. Since this takes place in the currentless state, maintenance of the contact m is hardly necessary.
