Description

Wendepolschaltung hei der Mutzbremsung von Einphasen-Reihenschlußmotoren, insbesondere Bahnmotoren Einphasen-Reihenschlußmotoren werden im Bahnbetrieb oft zur Nutzbremsung herangezogen. Zur richtigen Einstellung es Wendefeldes wird dabei in bekannter Weise der Ohmsche Nebenschluß, der im Fahrbetrieb zur Wendepolwicklung parallel geschaltet ist, abgeschaltet und durch einen induktiven Nebenschluß ersetzt. Außerdem wird in Reihe mit der Wendepolwicklung ein sogenannter Ohmscher Reihenwiderstand geschaltet. Für Nutzbremsschaltungen mit Bremsdrosselspulen im Ankerstromkreis ist eine Wendepolschaltung bekanntgeworden, bei welcher der induktive Nebenschluß auf die Bremsdrosselspule gewickelt ist, wodurch der Ohmsche Reihenwiderstand kleiner bemessen werden kann.Reversing pole connection in the Mutzbremsung of single-phase series motors, Railway motors in particular Single-phase series motors are often used in railway operations used for regenerative braking. The correct setting of the turning field is thereby achieved in a known way, the ohmic shunt that leads to the reversing pole winding during driving is connected in parallel, switched off and replaced by an inductive shunt. In addition, a so-called ohmic series resistance is created in series with the reversing pole winding switched. For regenerative braking circuits with braking reactors in the armature circuit is a reversing pole circuit has become known, in which the inductive shunt on the brake choke coil is wound, which reduces the ohmic series resistance can be measured.

Das für die Nutzbremsung erforderliche Wendefeld kann auch dadurch erreicht werden, daß der zum Fahrbetrieb benötigte Ohmsche Wendepolnebenschlul3 zur Bildung des phasenverschobenen Wendefeldes herangezogen wird. Erfindungsgemäße ist der auf den Kern der Bremsdrosselspule gewickelte Teil des induktiven Nebenschlusses mit dem Ohni,schen Nebenschluß in Reihe und ein unabhängiger induktiver Nebenschluß parallel zur Wendepolwicklung geschaltet.The turning field required for regenerative braking can also be achieved thereby can be achieved that the Ohmic Wendepolnebenschlul3 is used to form the phase-shifted turning field. According to the invention is the part of the inductive shunt wound on the core of the brake choke coil with the Ohni shunt in series and an independent inductive shunt connected in parallel to the reversing pole winding.

Ein Ausführungsbeispiel dieser Schaltung ist in Fig. i schematisch dargestellt. Es bedeuten: A den Anker, W die Wendepolwicklung, D, die Bremsdrosselspule. S einen Teil des induktiven Nebenschlusses, der auf die BremsdrosselspuleD- gewickelt ist, J den anderen Teil des induktiven Nebenschlusses, der auf einen unabhängigen Kern .aufgewickelt ist, -und O den für den Fahrbetrieb benötigten Ohmschen Wendepolnebengchluß. ß ist ein Schalter.An embodiment of this circuit is shown schematically in FIG shown. It denotes: A the armature, W the reversing pole winding, D, the brake choke coil. S part of the inductive shunt wound on the brake choke coil D- is, J is the other part of the inductive shunt that is on an independent The core is wound up, and O is the ohmic reversing pole shunt required for driving. ß is a switch.

Die Wirkungsweise der Schaltung ist aus dem Vektordiagramm Fig. z ersichtlich. Die Stromvektären sind mit dicken, weißen Pfeilen dargestellt und t[nit I bezeichnet, während die EMKe mit dünnen, schwarzen Pfeilen dargestellt und mit E bezeichnet sind. Die Indizes zeigen an, auf welches Element der Vektor zu beziehen ist.The mode of operation of the circuit is shown in the vector diagram Fig evident. The stream vectors are with thick, white arrows shown and t [nit I denotes, while the EMFs are shown with thin black arrows and are denoted by E. The indices indicate which element the vector is available.

Der Strom 1w in der Wendepolwicklun g eilt dem Ankerstrom I,1 um den Winkel vor. Die EMK EW ist ungefähr senkrecht zum Strom lw. Da der fast rein induktive NebenschlußJ parallel zur Wendepolwicklung geschaltet ist, liegt sein Strom 1i ungefähr in Phase mit dem - Wendepolstrom Ity. Die EMK ES der Wicklung S ist in Phase mit der EMK Ep der Bremsdrosselspule D@, ditzum Ankerstromla senkrecht steht. Die Differenz zwischen ES und Ettr bildet die EMKEo des Ohmschen Widerstandes0. In Gegenphase zu Eo. liegt der Strom lo im Widerstand O und in der W icklung S.The current 1w in the reversing pole winding leads to the armature current I, 1 by the Angle in front. The EMF EW is approximately perpendicular to the current lw. Since the almost purely inductive Shunt J is connected in parallel to the reversing pole winding, its current is approximately 1i in phase with the - reversing pole current Ity. The EMF ES of the winding S is in phase with the EMF Ep of the brake choke coil D @, so that the armature current la is perpendicular. The difference between ES and Ettr the EMKEo of the ohmic resistance forms 0. In opposite phase to Eo. the current lo lies in the resistance O and in the winding S.

Gegenüber den bekannten Schaltungen weist die vorliegende verschiedene Vorteile auf. Der sonst beim Bremsen in Reihe mit der Wendepolwicklung geschaltete Ohmsche Reihenwiderstand fällt weg; als Ersatz wirkt der für den Fahrbetrieb ohnehin benötigte Ohmsche Wendepolnebenschluß. Die Umschaltvorrichtung für den Reihenwiderstand fällt weg, Schaltoperationen sind nur noch in den Nebenschlußkreisen notwendig.Compared to the known circuits, the present one has different Benefits on. The otherwise connected in series with the reversing pole winding when braking Ohmic series resistance is eliminated; it acts as a substitute for driving anyway required ohmic reversing pole shunt. The switching device for the series resistance is no longer necessary, switching operations are only necessary in the shunt circuits.

Ein weiterer Vorteil der Schaltung liegt darin, daß die Wicklung S im Fahrbetrieb nicht kurzgeschlossen zu werden braucht, weil dann die Drosselspule D stromlos ist und daher in der Wicklung S nur noch eine sehr kleine, vernachlässigbare EMK erzeugt wird. Beim Übergang vom Fahrbetrieb in den Bremsbetrieb ist demnach für die Herstellung des richtigen Wendefeldes nur der Schalter B zu schließen. Bei den bekannten Schaltungen müssen fünf Kontakte verwendet werden, wovon zwei ungefähr den o,9fachen und drei ungefähr den o,3fachen Motorstrom führen. insgesamt Kontakte für den z,7fachen Motorstrom. Bei der erfindungsgemäßen Schaltung sind nur zwei Kontakte für den o,3-fachet: Motorstrom erforderlich, was ungefähr 1/; bis 1/5 des bisherigen Schaltgerätes erfordert.Another advantage of the circuit is that the winding S does not need to be short-circuited when driving, because then the choke coil D is de-energized and therefore only a very small, negligible one in the winding S EMF is generated. The transition from driving to braking is accordingly only close switch B to produce the correct turning field. at the known circuits have to use five contacts, two of which are approximately 0.9 times and three approximately 0.3 times the motor current. total contacts for z.7 times the motor current. In the circuit according to the invention there are only two Contacts for the o, 3-fold: Motor current required, which is about 1 /; up to 1/5 of the previous switching device requires.

Der Leistungsverbrauch der neuen Scli--tltung ist geringer als bei den bekannten, wodurch der Wirkungsgrad der Nutzbremsung verbessert wird.The power consumption of the new line is lower than that of the known ones, whereby the efficiency of regenerative braking is improved.
