Abstract

A static inverter 20 is protected on occurrence of a fault by an electrodynamic repulsion operating mechanism 10 which opens mechanical contacts 12 inserted in the phase conductors so as to isolate the faulty inverter or to switch to a different inverter. The electrodynamic mechanism 10 is actuated by a static control device. <IMAGE>
