<p>The ventilator (3) has an annular fixed part (31) adapted to be attached around a pluggable connection arm (21) of an electrical disconnection apparatus. A movable part (32) creates airflow when the movable part is moved, and is coupled with the fixed part. An autonomous power supply system (33) has a transformer comprising a primary circuit supplied with current circulating in the arm and a secondary circuit generating, in response, a secondary induced current to be supplied to a driving motor of the movable part. The movable part is in the form of a wheel with ventilation blades. An independent claim is also included for a cut-set cabinet.</p> |
