Description
Schalteinrichtung Das Hauptpatent betrifft einen Druckgasschalter mit Mehrfachunterbrechung und mit einer dazu in Reihe liegenden Trennschaltstelle für die Spannungsisolation, wobei .den einzelnen Leistungsunterbrechungsstellen Impedanzen parallel geschaltet sind, die so bemessen sind, daß die Spannung auf alle Leistungsunterbrechungsstellen gleichmäßig verteilt und der Reststrom durch einen Schalter abgeschaltet werden kann, der ohne Druckgas isoliert. Als Impedanzen werden sowohl Widerstände wie auch Kondensatoren in bestimmter Anordnung verwendet.Switching device The main patent relates to a gas pressure switch with multiple interruption and with an isolating switch point in series for voltage isolation, with .the individual power interruption points Impedances are connected in parallel, which are dimensioned so that the voltage on all power interruption points evenly distributed and the residual current through a switch can be turned off that isolates without compressed gas. As impedances Both resistors and capacitors are used in a certain arrangement.
Gegenstand der vorliegenden Erfindung ist nun eine weitere Verbesserung von Druckgasschaltern dieser _\rt, welche darin besteht, daß zum Zweck einer gleichmäßigeren Verteilung der Spannung auf den elektrisch und räumlich in Reihe geschalteten einzelnen Unterbrechungsstellen des Leistungsschalters die zu ihnen parallel geschalteten Impedanzen verschieden groß gewählt werden.The present invention now relates to a further improvement of compressed gas switches this _ \ rt, which consists in that for the purpose of a more uniform Distribution of the voltage to the individual electrically and spatially connected in series Breaker interruption points connected in parallel to them Impedances of different sizes can be chosen.
Da bekanntlich die äußeren Unterbrechungsstellen am höchsten beansprucht sind, d. h. die erste und letzte der in Reihe liegenden Unterbrechungsstellen, werden die Impedanzen, beispielsweise hochohmige Widerstände, so abgestuft, daß die stromvermindernde Wirkung derselben am stärksten bei den äußeren Schaltstellen ist und nach inneren Unterbrechungsstellen zu abnimmt. An Hand einer solchen Abstufung kann die Verteilung der Spannung über den einzelnen in Reihe geschalteten Unterbrechungsstellen beliebig bestimmt werden, was für die Abschaltung von ,hohen Spannungen mittels Druckgasschalter von sehr großem Vorteil ist.As is well known, the outer interruption points are the most stressed are, d. H. the first and last of the interruption points in series the impedances, for example high-value resistors, graded so that the current-reducing The effect of these is strongest in the outer switching points and inward Interruption points to decreases. Based on such a gradation, the distribution the voltage across the individual series-connected Interruption points can be determined as desired, what for the shutdown of, high voltages by means of Compressed gas switch is of great advantage.
