Description
Die Erfindung betrifft eine Streckenblockeinrichtung für Wechselstrombetrieb.The invention relates to a section block device for alternating current operation.
Die bisherige Wechselstromblockeinrichtung hat den schwerwiegenden Nachteil, daß ein fremder Wechselstrom oder auch pulsierender Gleichstrom, der auf irgendeinem Wege in das Blocksystem gelangt, die unbeabsichtigte Auslösung einer Blockierung bewirken kann.The previous AC block device has the serious disadvantage that an alien alternating current or pulsating direct current flowing on some Ways get into the block system which inadvertently cause a blockage can.
ίο Die Erfindung hat den Zweck, diesen Nachteil des Wechselstromblockes zu beseitigen, solches wird dadurch erreicht, daß der durch den Betriebswechselstrom (Induktor) zu betätigende Auslöse- oder Blockmagnet des geblockten Feldes A mittels eines von einem über die Leitung zum entblockten Feld B verlaufenden Ruhestrom durchflossenen Relais Ra normalerweise abgeschaltet gehalten wird, dagegen nur während des Vorganges der Entblockung (seitens des FeI- ao des J5) infolge Unterbrechung des Strornweges das Relais Ra an die Leitung angeschaltet und der Einwirkung der Wechselstromentsendung (Drehen der Induktorkurbel) zugänglich gemacht wird, zum Zwecke, die unbeabsichtigte Auslösung einer Blokkung durch fremden Wechselstrom (bzw. pulsierenden Gleichstrom) während der Wirkpausen des Betriebswechselstromes zu verhindern. ίο The invention has the purpose of eliminating this disadvantage of the alternating current block, this is achieved by the release or block magnet of the blocked field A to be actuated by the operating alternating current (inductor) by means of a quiescent current running from a line to the unblocked field B. relay R a through which it flows is normally kept switched off, but only during the deblocking process (on the part of the FeI ao of J5) as a result of the interruption of the current path the relay R a is switched on to the line and made accessible to the effect of the alternating current transmission (turning the inductor crank) for the purpose of preventing the unintentional triggering of a blockage by an external alternating current (or pulsating direct current) during the pauses in the operating alternating current.
Die Wirkungsweise geht aus der Schaltung und der Abbildung hervor, in welcher das Blockfeld A ungeblockt, das Feld B in entblocktem Zustand dargestellt sind. Ist A ein verriegeltes Feld, so ist durch die niedergedrückte Verschlußstange in A ein Stromkreis über Relais Ra geschlossen, der über das entblockte FeIdB* wie folgt verläuft:The mode of operation is evident from the circuit and the figure in which the block field A is shown unblocked and the field B is shown unblocked. A is a locked box, a relay circuit via R a is closed by the depressed shutter bar in A, * as extending over the unblocked FeIdB follows:

Von Erde£a über Batterie B, Relais Ra, Kontakt 5, unteren Kontakt 4, oberen Kontakt i, Leitung L, oberen Kontakt 1, oberen Kontakt 4 nach Erde. Drückt B die Druckstange nieder, um in A die Blockierung zu lösen, so fällt zunächst, da der Stromkreis bei Kontakt 4 getrennt wird, das Relais Ra ab und öffnet seinen Kontakt 5, wodurch der Stromkreis für Relais Rb weiter unterbrochen bleibt. Über den geschlossenen Kontakt 6 wird der Blockmagnet BMa an die Leitung gelegt. Gleichzeitig zieht das Relais Rb im Blockfeld B über den Kontakt 3 an. Wird bei niedergedrückter Druckstange in B der Induktor /6 betätigt, so fließt ein Wechselstrom über Kontakt 2 in B über die Leitung nach A und daselbst über den Blockmagneten BM0, wodurch derselbe seinen Anker anzieht und die Riegelstange freigibt. Beim Loslassen der Druckstange in B bleibt das Relais Rb erregt. (Zu diesem Zwecke ist es erforderlich, daß der Kontakt 1 schon fließt, bevor 3 trennt.) Sobald die Druckstange in B losgelassen wird, werden die Kontakte 2, 3 geöffnet, und der Induktor wird von der Leitung abgetrennt.From earth £ a via battery B, relay R a , contact 5, lower contact 4, upper contact i, line L, upper contact 1, upper contact 4 to earth. If B presses the push rod down in order to release the blockage in A , the relay R a falls, as the circuit is separated at contact 4, and opens its contact 5, whereby the circuit for relay R b remains interrupted. The block magnet BM a is placed on the line via the closed contact 6. At the same time, relay R b in block field B picks up via contact 3. If the inductor / 6 is actuated while the push rod in B is depressed, an alternating current flows via contact 2 in B via the line to A and there via the block magnet BM 0 , which attracts its armature and releases the locking bar. When the push rod in B is released, relay R b remains energized. (For this purpose it is necessary that contact 1 already flows before 3 disconnects.) As soon as the push rod in B is released, contacts 2, 3 are opened and the inductor is disconnected from the line.
Die Induktoren und Blockmagnete eines jeden Blockfeldes liegen also nur an der Leitung, wenn die Druckstange niedergedrückt ist. In blockiertem Zustande bleibt ein fremder Wechselstrom, der auf irgendeine Weise in das Blocksystem gelangen kann, ohne Wirkung, da das Relais R in jedem Falle in erregtem Zustande erhalten bleibt. Fließt während des Vorganges der Blockierung kein Ruhestrom, sondern der Wechselstrom des Blockinduktors, so kann ebenfalls jeder Störstrom die beabsichtigte Wirkung der Entblockung nicht verhindern.The inductors and block magnets of each block field are only on the line when the push rod is depressed. In the blocked state, an external alternating current, which can get into the block system in any way, has no effect, since the relay R remains in an excited state in any case. If no quiescent current flows during the blocking process, but the alternating current of the blocking inductor, any interference current cannot prevent the intended effect of the unblocking.
