Functional test process for a mechanical switching element

摘要

In the functional test process for a mechanical switching element, particularly 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 valve. This makes it possible to stop the movement of the core (2) and the plunger (4) without triggering the power switch.
