Einrichtung zum selbsttätigen Abschalten gestörter Strecken bei elektrischen Leitungsnetzen.Device for the automatic shutdown of disturbed lines in electrical line networks.
Zusatz zum Patent 403934. Additional patent 403,934th
Patentiert im Deutschen Reiche vom 29. März 1923 ab. Längste Dauer: 6. März 194t.Patented in the German Empire on March 29, 1923. Longest duration: March 6, 194t.
Zur selbsttätigen Abschaltung gestörter Strecken bei elektrischen Leitungsnetzen ist Jm Hauptpatent bereits angegeben, daß die Abschaltung durch das an ßich bekannte Zusammenwirken zweier Kontakte herbeigeführt wird, von denen der eine mittels eines Relais entsprechend der jeweiligen Entfernung von der Störungsstelle verschieden eingestellt, der andere dagegen durch ein Zeitwerk gesteuert wird und das Relais aus einem Wattrelais und einem diesem entgegenwirkenden Stromrelais zusammengesetzt ist. Wenn dann mindestens das eine dieser Relais so ausgebildet ist, daß seine Wirkung, sich mit der Verstellung in dem einen oder andern Sinne ändert, bildet die jeweilige Einstellung im Störungsfalle eiii Maß für die Entfernung von der Störungsstelle. Auf diese Weise läßt es sich erreichen, daß der vom Zeitwerk gesteuerte Kontakt bei den unmittelbar für die gestörte Strecke in Betracht kommenden Auslösevorrichtungen den kürzesten Weg zurückzulegen hat und in-For the automatic shutdown of disturbed lines in electrical line networks Already stated in the main patent that the disconnection by the interaction known to me two contacts is brought about, one of which by means of a relay according to the respective distance from The fault location is set differently, while the other is controlled by a timer and the relay is made up of a water relay and a current relay counteracting this is composed. If then at least one of these relays is designed so that its effect, which changes with the adjustment in one sense or the other, forms the respective setting in the event of a malfunction eiii Measure of the distance from the point of failure. In this way it can be achieved that the contact controlled by the timer with the direct for the disturbed route in The tripping device in question has to cover the shortest distance and
folgedessm die zu diesen gehörigen Schalter zuerst ausgelöst werden.consequently the switches belonging to these are triggered first.
Gemäß der Erfindung ist es nun nicht unbedingt notwendig, einerseits ein Wattrelais und anderseits ein Stromrelaiiis zu verwenden. Es läßt sich vielmehr die gleiche Wirkung auch dadurch erzielen, d'a!ß an die Stelle des Wattrelais ein Spannungsrelais tritt, wie dies beispielsweise die Zeichnung veranschaulicht. Damit von den verschiedenen Auslösevorrichtungen einer Abzweigistation ianmer nur die unmittelbar der gestörten Strecke zugeordnete in Tätigkeit tritt, müssen in diesem Falle jedoch besondere Maßnahmen getroffen werden, da die Strömungsrichtung der elektrischen Energie durch das Relais selbst nicht mehr ohne weiteres zum Ausdruck gelangt. Zu diesem Zwecke kann etwa ein besonderes WattneMs angebracht werden, welches das Zeitwer'k für die Auslösevorrichtungen derjenigen Schalter sperrt, über die der Energiefluß nach der Abzweigstation hin verläuft und nur die der übrigen Schalter freigibt. According to the invention, it is now not necessary necessary to use a Wattrelais on the one hand and a Stromrelaiiis on the other. Rather, the same effect can also be achieved by adding d'a! Ss to the place of the Wattrelais a voltage relay occurs, as illustrated for example in the drawing. So from the various release devices of a branching station In any case, only the one directly assigned to the disturbed route has to be activated In this case, however, special measures must be taken, since the direction of flow the electrical energy through the relay itself is no longer readily expressed got. For this purpose a special WattneM can be attached, which the Zeitwer'k locks for the tripping devices of those switches via which the flow of energy to the branching station runs and only enables the other switches.
as Zweckmäßig wird für dais Stromrelaiis die Ausführung so getroffen, daß seine Wirkung, also bei dem Ferrarisinstrument das Drehmoment, sich dem Quadrate des Ausschlagswdnkels entsprechend ändert. In diesem Falle wird der Ausschlagswdnkel des zusammengesetzten Relais jeweils der Entfernung von der Störungsstelle proportional.he is useful for the power relay Made in such a way that its effect, i.e. the torque of the Ferrari instrument, changes according to the square of the deflection angle. In this case becomes the angle of deflection of the composite relay in each case the distance from the Fault location proportional.
