Description

Selektives Schutzsystem für elektrische Energieübertragungsanlagen. Zusatz zum Patent q.02857. In dem Hauptpatent ist ein Spannungsverlustrelais beschrieben, bei dem der durch einen Überstrom in der Zuleitung verursachte Spannungsverlust dadurch bestimmt wird, daß in den Sekundärstromkreis des Stromwandlers ein diesem Zuleitungswiderstand entsprechender Widerstand eingeschaltet wird. Die an den Klemmen dieses Widerstandes herrschende Spannung wird zum Betrieb des Selektivrelais benutzt.Selective protection system for electrical power transmission systems. Addition to patent q.02857. In the main patent, a voltage loss relay is described, in which the voltage loss caused by an overcurrent in the supply line is determined by the fact that in the secondary circuit of the current transformer a this Lead resistance corresponding resistance is switched on. The ones on the clamps The voltage prevailing at this resistance is used to operate the selective relay.

Erfolgt die Stromlieferung in das Leitungsnetz jedoch von mehreren Seiten, so wechselt, je nach der Verteilung der Netzbelastung auf die stromliefernden Werke, auch das die Schaltstation speisende Kraftwerk und damit die Länge der Stromzuleitung von der tat->.ächlichen Stromquelle bis zum Ort des betreffenden Relais.However, if the electricity is supplied to the grid by several people Sides, so changes, depending on the distribution of the network load on the power-supplying Works, including the power station feeding the switching station and thus the length of the power supply line from the fact ->. spatial power source to the location of the relay in question.

In diesem Falle ändert sich aber auch für die durch die Schaltstation hindurchgehende Speiseleitung die Energierichtung.In this case, however, also changes for the through the switching station through feed line the direction of energy.

Die Erfindung besteht darin, mit Hilfe eines Energierichtungsrelais den in den Stromwandlerkreis einzubauenden Widerstand durch entsprechende Umschaltung auf einen von dem Widerstandswert der maßgebenden Stromzuleitung zur Schaltstation abhängigen Wert zu bringen.The invention consists in using an energy direction relay the resistor to be built into the current transformer circuit by switching accordingly on one of the resistance value of the relevant power supply line to the switching station to bring dependent value.

Durch die Verwendung eines Energierichtungsrelais wird somit erreicht, daß das einfache Spannungsverlustrelais auch für solche Netzverhältnisse seine selektive Wirkung behält, bei denen die Schaltstation mit dem betreffenden Relais von verschiedenen Seiten Strom zugeführt -erhält.By using an energy direction relay, it is achieved that the simple voltage loss relay is selective even for such network conditions Retains effect in which the switching station with the relevant relay of different Pages current fed -receives.
