Description

Vorrichtung zum Anzeigen außergewöhnlicher Vorgänge oder zum Abschalten eines gestörten Leitungsteiles Zusatz zum Patent 421040 Gegenstand des Hauptpatentes ist eine auf Strom und Spannung ansprechende Relaisanordnung für Drehstrom, bei der für je zwei Phasen .ein Relais verwendet wird, dessen Stromspule von der Differenz der zwei Phasenströme durchflossen wird. Es sind also für jede Phase zwei Stromwandler vorgesehen. Um nun Stromwandler zu sparen, werden nach der Erfindung insgesamt nur &ei Stromwandler, nur einer in jeder Phase, verwendet, deren Sekundärwicklungen in Dreieck geschaltet werden. Die Stromspulen. der drei vorgesehenen Relais werden in Stern ges chaltet und die offenen Enden an die Verbindungspunkte der in Dreieck geschalteten Sekundärwicklungen der Stromwandler angeschlossen. - Die Spannungsspulen der drei, Relais sind wie bei der Vorrichtung nach dem Hauptpatent zwischen die entsprechende verkettete Spannung geschaltet.Device for displaying unusual processes or for switching off of a disturbed line part Addition to patent 421040 Subject of the main patent is a current and voltage responsive relay arrangement for three-phase current, bei a relay is used for every two phases, the current coil of which depends on the difference through which two phase currents flow. So there are two current transformers for each phase intended. In order to save current transformers, according to the invention only & ei current transformer, only one in each phase, used their secondary windings be connected in delta. The power coils. of the three relays provided switched in star and the open ends to the connection points in triangle connected secondary windings of the current transformer. - The tension coils of the three, relays are, as in the device according to the main patent, between the corresponding line-to-line voltage switched.

Die Zeichnung zeigt ein Ausführungsbei- . spiel der Erfindung. .I, 2 und 3 sind die Siekundärseibexi der ,in jeder Phase befindlichen Stromwandler,' ee 5n ;Dreieck geschaltet sind. Die drei Verbindungspunkte der Drei,-eckwcklung sind mit ja einem Ende der Stromspulen der Relais 4, 5 und 6 verbunden, ;deren .andere Erid#en kurzbeschlossen sü#;d. Die Spannungsspulen der Relais liegen an der entsprechenden . verketteten Spannung. Wie aus 'der Zeichnung zu ersehen ist, fließt durch jede Stromspule d;ie Differenz zweier Phasenströme, während die, Spannungsspule an der verketteten Spannung zwischen. diesen beiden Phasen liegt. Es wird also mit @dieser Anordnung derselbe Zweck erreicht wie mit seiner Vorrichtung nachdem Hauptpatent, bei Verwendung nur dreier Stromwandler anstatt der früheren :sechs Stromwandler.The drawing shows an exemplary embodiment. game of invention. .I, 2 and 3 are the secondary seibexi of the current transformers in each phase, 'ee 5n; are triangular connected. The three connection points of the triangular winding are connected to one end of the current coils of the relays 4, 5 and 6, their .other Erid # en short-circuited south. The voltage coils of the relays are connected to the corresponding one. chained tension. As can be seen from the drawing, the difference between two phase currents flows through each current coil, while the voltage coil at the line-to-line voltage between. these two phases. The same purpose is achieved with this arrangement as with his device according to the main patent, using only three current transformers instead of the previous ones: six current transformers.
