<p>A device making it possible to automatically restore the line current in the event of the burning-out of one or more elements (5) forming part of a series arrangement, characterised in that it comprises a semiconductor arrangement (3) shunted onto each element (5) of the series arrangement, a first terminal (7) being connected on the input side of the said element (5) and a second terminal (9) being connected on the output side of the said element (5), the said semiconductor arrangement (3) being triggered and held in the conducting state once the voltage across its terminals (7, 9) becomes greater than a voltage threshold previously fixed between its gate (11) and the said second terminal (9). <IMAGE></p> |
