Abstract
Verzögerungseinrichtung mit Energiespeicher Delay device with energy storage
Bekannte Verzögerungseinrichtungen beruhen auf ei nem periodischen Öffnen und Schließen von Kontakt stellen zur Strombegrenzung. Dies kann zu einem vorzeitigen Verschleiß der Kontakte führen. Known delay devices are based on egg Periodic opening and closing of contacts to limit the current. This can lead to a cause premature wear of the contacts.
Eine neuartige Verzögerungseinrichtung (10, 34, 50) ist mit einem Energiespeicher (12, 38, 52) kombi niert, wobei mechanische Hemmittel (16, 24) oder fluidische Hemmittel (41, 66) benutzt werden, um die Rückstellung durch den Energiespeicher (12, 38, 52) zeitlich zu verzögern. A new type of delay device (10, 34, 50) is combi with an energy storage (12, 38, 52) niert, whereby mechanical inhibiting means (16, 24) or fluidic inhibitors (41, 66) can be used to the provision by the energy store (12, 38, 52) to be delayed.
Mit der neuen Verzögerungseinrichtung ausgestattete Schaltgeräte finden Anwendung insbesondere als se lektive Sicherungsautomaten. Equipped with the new delay device Switchgear is used especially as se selective circuit breakers.
