Short circuit switch for short-circuiting e.g. gate turn-off thyristor of inverter of high voltage direct current equipment, has striker that is triggered to drive detachment of hook from fixation element and unblocking of operating member

摘要

The switch has a release member i.e. hook (7), mounted between an operating member (5) and a fixation element (8) e.g. bearing. An electric striker (12) e.g. bistable electromagnet integrated electric striker, includes a percussion head (12.1) translatable from a retracted state when the striker is reinforced, to an exited state when the striker is triggered. The striker is triggered to drive detachment of the hook from the fixation element, unblocking of the operating member, triggering of an elastic element (9) e.g. spring, translation of the operating member and closing of the switch. An independent claim is also included for an electric circuit comprising electronic components.
