Abstract
Elektrische Schalteinrichtung für hohe Schaltspan nungen. Electrical switching device for high switching voltage mentions.
Die Erfindung betrifft einen Stromunterbrecher für Hochspannungsnetze mit mindestens 2 in Reihe geschalteten Schaltern (S 1) und (S 2) mit voneinander abweichenden Un terbrechungsprinzipien. Der Schalter (S 1) unterbricht bei hohen zulässigen Schaltzahlen alle ohmschen und induktiven Lastströme mit kurzen Lichtbogenzeiten allein, während der Schalter (S 2) eine Zeitspanne (Δ t) von einigen Millisekunden nach Schalter (S 1) öffnet und in Serie zu Schalter (S 1) die Unterbrechung von kapazitiven Strömen und Störströmen mit hohen Schaltspannungen bewirkt. Schalter (S 1) ist vor zugsweise ein Vakuum-Lastschalter mit vergleichsweise ger inger Nennspannung, während Schalter (S 2) ein Gas- oder Flüssigkeits-Lastschalter geringer Schaltleistung sein kann, der gleichzeitig auch die Funktion eines Trennschalters erfüllt. The invention relates to a circuit breaker for High-voltage networks with at least 2 connected in series Switches (S 1) and (S 2) with mutually different Un principles of refraction. The switch (S 1) interrupts high permissible number of switching operations all ohmic and inductive Load currents with short arcing times alone during the Switch (S 2) a time span (Δ t) of a few milliseconds after switch (S 1) and in series with switch (S 1) Interruption of capacitive currents and interference currents with high switching voltages. Switch (S 1) is in front preferably a vacuum load switch with a comparatively low nger nominal voltage, while switch (S 2) a gas or Liquid load switch low switching capacity can be which also functions as a disconnector Fulfills.
