Description
Einrichtung zum elektrischen Bremsen von Triebfahrzeugen mit Einphasen Reihenschlussmotoren mittels Widerstandsbremsung der letzteren. Die bisherigen Widerstandsbremseinrich- tungen zum elektrischen Bremsen von Trieb fahrzeugen mit Einphasen-Reihenschlussmo- toren eignen sich bekanntlich nicht zur Still standsbremsung, sofern nicht besondere Hilfs mittel angewendet werden. Um diesen Man gel zu beheben, ist erfindungsgemäss die Bremsanordnung derart umschaltbar, dass sie auch als eine fremdgespeiste Rückstrom- Stillstandsbremse verwendbar ist.
Der Auf wand an Mehrmaterial ist dabei im Verhält nis zur Sicherheitserhöhung gering.
Ein Ausführungsbeispiel des Erfindungs gegenstandes ist in der beiliegenden Zeich nung schematisch dargestellt. Fig. 1 zeigt die normale Schaltung für motorische Fahrt, Fig. 2 die entsprechende Schaltung bei Wi derstandsbremsung und Fig. ä die Zuschal- tungs für Rückstrom-Stillstandslbremsung. In allen drei Figuren ist 1 der Fahrzeugtrans formator. 2 eine Überschaltspule, <B>3</B> ein Wendeschalter, 4 ein Triebmotor-Rotor, 5 die Triebmotor-Erregerwicklung und 6 ein Bremswiderstand.
Wie ersichtlich, wird der für die Schal tung nach Fig. 2 benötigte Widerstand 6 auch in der Schaltung nach Fig. $ benützt, also durch einfache Umschaltung unter Ver wendung des gleichen Bremswiderstandes die normale Widerstandsbremsung in eine fremd gespeiste Rückstrom-Stillstandsbremsung um geschaltet.
Device for electrical braking of traction vehicles with single-phase series motors by means of resistance braking of the latter. It is known that the previous resistance braking devices for the electrical braking of traction vehicles with single-phase series motors are not suitable for braking to a standstill unless special aids are used. In order to remedy this deficiency, according to the invention the brake arrangement can be switched in such a way that it can also be used as an externally fed reverse current standstill brake.
The cost of additional material is low in relation to the increase in security.
An embodiment of the subject invention is shown schematically in the accompanying drawing. 1 shows the normal circuit for motorized travel, FIG. 2 shows the corresponding circuit for resistance braking, and FIG. 1 shows the connection for reverse current standstill braking. In all three figures, 1 is the vehicle transformer. 2 a switchover coil, <B> 3 </B> a reversing switch, 4 a drive motor rotor, 5 the drive motor excitation winding and 6 a braking resistor.
As can be seen, the resistor 6 required for the circuit according to FIG. 2 is also used in the circuit according to FIG. $, That is, the normal resistance braking is switched to an externally supplied reverse current standstill braking by simply switching using the same braking resistor.
