FUNCTIONAL TEST PROCESS FOR A MECHANICAL SWITCHING ELEMENT

摘要

With the proposed functional test process for a mechanical switching element, specifically a trigger in a high-voltage power switch, a coil core (2) is set in motion by the magnetic action of a current flowing through a coil (1). The electrical pulse is cut off as soon as the derivative of the measured current characteristic reaches a particular value. This ensures that the movement of the core (2) and plunger (4) can always be stopped without triggering the power switch.
