Description
Bei selbsttätig arbeitenden Gleichrichteranlagen ist es erwünscht, daß die Schaltvorgänge ohne Zuhilfenahme einer äußeren Hilfskraft, wie z. B. einer Gleichstromquelle und den zugehörigen Apparaten, erfolgen. Bei der den Gegenstand der Erfindung bildenden Einrichtung zur selbsttätigen Einschaltung des gleichstromseitigen, mit einem Einschalt- und zugleich Haltemagneten versehenen Höchst-Stromschalters eines Quecksilberdampfgleichrichters ist die Spule dieses Magneten in den Erregerstromkreis unmittelbar oder unter Zuhilfenahme von Parallelwiderständen eingeschaltet. In the case of automatically operating rectifier systems, it is desirable that the switching operations without the help of an external helper, such as B. a DC power source and the associated apparatus. When forming the subject of the invention Device for automatic switching on of the DC side, with a switch-on and At the same time holding magnets provided high current switch of a mercury vapor rectifier is the coil of this magnet in the excitation circuit directly or with the aid switched on by parallel resistors.
Das Schaltbild zeigt ein Ausführungsbeispiel für die Erfindung. Es bedeutet: ι Gleichrichter, 2 Erregeranoden, 3 Erregertransformator, 4 Erregerwiderstand, 5 Höchst stromschalter, 6 die zu letzterem gehörige, in den Erregerstromkreis des Gleichrichters eingeschaltete Spule des Einschalt- und Haltemagneten, 7 die Höchststromauslösespule, welche der Einschaltspule 6 entgegenwirkt, 9 Hilfskontakte, die vom Schalter 5 betätigtThe circuit diagram shows an embodiment for the invention. It means: ι rectifier, 2 excitation anodes, 3 excitation transformer, 4 excitation resistance, 5 maximum current switch, 6 the one belonging to the latter, in the excitation circuit of the rectifier activated coil of the closing and holding magnet, 7 the maximum current release coil, which counteracts the closing coil 6, 9 auxiliary contacts which are actuated by the switch 5
*5 werden und bei geschlossenem Schalter 5 ebenfalls geschlossen sind.* 5 and when the switch is closed 5 are also closed.
Die dargestellte Einrichtung arbeitet folgendermaßen: The device shown works as follows:
In dem Augenblick, in dem die Erregung einsetzt, fließt ein Strom durch die Spule 6 des Einschalt- und Haltemagneten, indem die Kontakte 9 durch eine nicht gezeigte Vorrichtung im Einschaltmoment überbrückt worden sind. Dadurch wird der Schalter 5 geschlossen und, solange der Erregerstrom fließt, geschlossen gehalten. Mit dem Schließen des Hauptschalters 5 schließen sich auch die Hilfskontakte 9, so daß die vorerwähnte Überbrückung wieder aufgehoben werden kann. Tritt nun ein Kurzschluß auf, so reißt die Höchststromspule 7 den Schalter 5 heraus und öffnet auch die Hilfskontakte 9.At the moment when the excitation begins, a current flows through the coil 6 of the closing and holding magnet by the contacts 9 by a device not shown have been bridged at the moment of switch-on. This closes switch 5 and, as long as the excitation current flows, kept closed. With the closing of the Main switch 5 also close the auxiliary contacts 9, so that the aforementioned bridging can be canceled again. If a short circuit now occurs, the high-current coil 7 pulls out the switch 5 and also opens the auxiliary contacts 9.
