Abstract

Verfahren zur Justierung von zu jeder Phase gehörenden, als Thermobimetall- oder Formgedächtnislegierungsstreifen ausgebildeten thermischen Auslöser eines elektrischen Schaltgerätes, insbesondere eines Motorschutzschalters, deren Aulösebewegungen bei einem bestimmten Nennstrom über Übertragungsglieder auf einen Auslösemechanismus übertragen werden und mit einem Einstellelement zur Einstellung des Schaltgerätes auf einen bestimmten Nennstrom, folgenden Verfahrensschritten:

  • Messen der Abstände jedes Bimetalls (10,11,12) von einem zum in Auslösestellung befindlichen Auslösemechanismus gehörigen Bauteil (16), bei einem bestimmten Strom,
  • Fertigung der Übertragungsglieder (13,14) und deren Montage entsprechend den Meßergebnissen,
  • Verändern der Stellung des Einstellelementes (17,18) zur Auslösung des Auslösemechanismus,
  • Anpassen der dem Einstellelement zugeordneten Skalierung.

Method for adjusting the thermal triggers of an electrical switching device, in particular a motor protection switch, which are formed as thermobimetal or shape memory alloy strips and whose release movements at a certain nominal current are transmitted to a tripping mechanism via transmission elements and with an adjusting element for setting the switching device to a certain nominal current following process steps:
  • Measuring the distances of each bimetal (10, 11, 12) from a component (16) belonging to the release mechanism in the release position, at a specific current,
  • Production of the transmission elements (13, 14) and their assembly according to the measurement results,
  • Changing the position of the adjusting element (17, 18) to trigger the trigger mechanism,
  • Adjust the scaling assigned to the setting element.
