Description

Einrichtung, um -den Potentialunterschied zwischen den beiden Wicklungen eines Hochspannungstransformators zu vermindern. Bei der Einrichtung nach dem Hauptpatent 336779 wird zur Verminderung des zwischen den beiden Wicklungen eines Hochspannungstransformators bestehenden Potentialunterschiedes den an ihren Enden die geringere Spannung aufweisenden Wicklungen von außen ein Potential dauernd aufgedrückt, wobei diese Wicklungen von dem Netz durch Hilfstransformatoren isoliert sind und auf diese Weise auf jenem Potential erhalten werden.Device to reduce the potential difference between the two windings of a high-voltage transformer. In the device according to the main patent 336779 , in order to reduce the potential difference between the two windings of a high-voltage transformer, a potential is continuously applied to the windings with the lower voltage at their ends, these windings being isolated from the network by auxiliary transformers and in this way on that potential can be preserved.

Statt der Hilfstransformatoren kann man gemäß der Erfindung irgendwelche zur Energieübertragung geeignete Vorrichtungen verwenden, die zugleich die zu ihren beiden Seiten auf dem Wege der Energieübertragung liegenden Leiter ihrem Potentialniveau nach beeinflußbar lassen, beispielsweise Kondensatoren.Instead of the auxiliary transformers, you can according to the invention any Use suitable devices for energy transmission, which are at the same time their conductors lying on the path of energy transmission on both sides of their potential level can be influenced after, for example capacitors.

Die Zeichnung zeigt dies in einem Ausführungsbeispiel. An die Stromquelle d sind die Kondensatoren e und f je mit einer ihrer beiden Belegungen angeschlossen. Dadurch sind die mit den anderen Belegungen der Kondensatoren e bzw. f verbundenen Primärwicklungen l bzw. m der Hochspannungstransformatoren n bzw. o von dem Netz isoliert. Zweckmäßig ist die Verbindungsstelle der beiden Hochspannungswicklungen p und q mit der Erde verbunden. Es weisen dann; wenn - um ein Zahlenbeispiel zu nennen - die gesamte Sekundärspannung zwischen den Klemmen x und y der Hochspannungswicklungen f bzw. q xoo Kilovolt beträgt, die Klemmen x und y einander entgegengesetzt gleiche Spannungen gegenüber der Erde von je 50 Kilovolt auf. Die Mittelpunkte z und 2 der beiden Hochspannungswicklungen, deren Spannung gegenüber Erde demnach entsprechend je 25 Kilovolt beträgt, sind jede für sich mit der Primärwicklung l bzw. in ver- bunden. Daher beträgt der Potentialunterschied zwischen dem Ende x bzw. y der Hochspannungswicklung P bzw. q und der Primärwicklung l bzw. m 50 - 25 = 25 Kilovolt.The drawing shows this in an exemplary embodiment. The capacitors e and f are each connected with one of their two assignments to the current source d. As a result, the primary windings l and m of the high-voltage transformers n and o connected to the other assignments of the capacitors e and f are isolated from the network. The junction of the two high-voltage windings p and q is expediently connected to earth. It then show; if - to give a numerical example - the total secondary voltage between the terminals x and y of the high-voltage windings f or q is xoo kilovolts, the terminals x and y have oppositely equal voltages to earth of 50 kilovolts each. The center points z and 2 of the two high-voltage windings, whose voltage with respect to earth is accordingly 25 kilovolts each, are each connected to the primary winding 1 or in . Therefore, the potential difference between the end x or y of the high-voltage winding P or q and the primary winding l or m is 50-25 = 25 kilovolts.
