Zahnsoktor t auskliiikon, Eine weitere Forderung ist, dass der Steuerapparat solange stromlos bleibe, als der Zahnaektor t durch don Sperrkörper s festgehalten wird. Zu diesem Zwecke ist es nicht erforderlich sämtliche Kontakthebel der Umschaltvorrichtung
EMI2.1
Schalter d, e, f für die andere Drehrichtung des Motors geschlossen. Der Seerrkörper t1, der mit dem Zahnsektor t gekuppelt ist, hindert den Hauptschalter c solange, als der Sektor t in seiner Anfangslage festgehalten wird.
Unter Umständen, z. H. bei einem Anlasser für Drehstrommotoren, sind mehrere solcher Klinken t1 zur Sperrung der Hauptschalthebel erforderlich, Erfolgt ferner das Schliessen der Kontakte der Umschaltvorrichtung nicht-wie in der Zeichnung-durch Federkraft, sondern mittels irgend einer zwang- läufigen Steuerung, so müssen federnde Zwischenglieder eingefügt werden, um einer Zerstörung der Antriebsteile vorzubeugen.
Die Wirkungsweise der Vorrichtung ist also eine derartige, dass die Anlasswiderstände erst dann unter Strom gesetzt und in irgendwelcher Weise geschaltet werden können, wenn nach vollendetem Seilzuge eine mechanische Sperrvorrichtung den Schaltmechanismus freigegeben hat.
EMI2.2
1. Aufzugsanlasser mit Seilsteuerung und selbsttätig verzögerter Abschaltung der Anlasswiderstände, gekennzeichnet durch eine erst in den beiden Endstellungen des Seilzuges ausser Tätigkeit zu setzende mechanische Sperrvorrichtung (2) für die Einschaltbewegung der Anlasskontakte (g bis m).

Zahnsoktor t auskliiikon, Another requirement is that the control apparatus remain currentless as long as the Zahnaektor t is held by the locking body s. For this purpose it is not necessary to use all the contact levers of the switching device
EMI2.1
Switches d, e, f closed for the other direction of rotation of the motor. The Seerrkörper t1, which is coupled to the toothed sector t, prevents the main switch c as long as the sector t is held in its initial position.
Under certain circumstances, e.g. In the case of a starter for three-phase motors, several such pawls t1 are required to lock the main shift lever. If the contacts of the switching device are not closed by spring force, as in the drawing, but by some kind of positive control, then resilient intermediate links must be used inserted in order to prevent destruction of the drive parts.
The mode of operation of the device is such that the starting resistors can only be energized and switched in any way when a mechanical locking device has released the switching mechanism after the cable has been pulled.
EMI2.2
1. Elevator starter with rope control and automatic delayed disconnection of the starting resistors, characterized by a mechanical locking device (2) for the switch-on movement of the starting contacts (g to m), which is only deactivated in the two end positions of the cable.
