Description

Einrichtung zur Unterdrückung des Erdschlußstromes von Hochspannungsnetzen. Zusatz zum Patent 304823. In Netzen sehr hoher Spannung glimmen im Erdschlußfalle die beiden nicht vom Erdschluß betroffenen Phasen. Hierbei steigt deren Kapazität nicht unbeträchtlich -an. Es ist beispielsweise möglich, daß in einem ioo ooo-Volt-l#Tetz der Erdschlußstrom verhältnismäßige Unterschiede von über 2o Prozent infolge dieser Kapazitätszunahme zeigt, je nachdem nach den wechselnden Betriebsverhältnissen oder nach der Lage des Erdschlußpunktes der Erdschluß unter 115 000 oder ioo ooo Volt erfolgt. Derartige Verstimmungen von 2o Prozent sind im allgemeinen unzuträglich.Device for suppressing the earth fault current in high voltage networks. Addition to patent 304823. In networks with very high voltage, the two phases not affected by the earth fault glow in the event of an earth fault. Here, their capacity increases not insignificantly. It is possible, for example, that in a 100,000 volt network the earth fault current shows relative differences of over 20 percent as a result of this increase in capacity, depending on the changing operating conditions or the location of the earth fault, the earth fault below 115,000 or 100,000 volts he follows. Such upsets of 20 percent are generally unsuitable.

Die Kleinhaltung des Erdschlußreststromes ist eine der Aufgaben der Erdschlußspule. Sie wird im beschriebenen Fall nicht erfüllt, wenn die Induktivität praktisch unveränderlich ist.Keeping the residual current to earth faults small is one of the tasks of Earth fault coil. It is not met in the case described if the inductance is practically unchangeable.

Gemäß der Erfindung werden die magnetischen Eigenschaften der Erdschlußspule so gewählt, daß ihre Charakteristik der Charakteristik des Erdschlußstromes der glimmenden Leitungen angepaßt ist, derart, daß stets vollendete oder annähernd vollendete Kompensation vorhanden ist.According to the invention, the magnetic properties of the earth leakage coil chosen so that their characteristic of the characteristic of the earth fault current of the smoldering lines is adapted in such a way that always completed or nearly completed Compensation is available.

Es ist eben so gut möglich, im ganzen Arbeitsbereich der Spule eine Fehlabgleichung gewollter Größe innezuhalten.It is just as possible to have one in the entire working range of the coil Pausing misalignment of the desired size.
