Abstract (en)
[origin: WO2014079877A1] The control device according to the invention can be used to very quickly activate the opening of the circuit breakers used in medium- and high-voltage networks. The spring used in the control device is a composite spring, in a curved C or Ω shape. The spring (1) has a first fixed end (2) and a second mobile end (3) that is pivotably connected with the end of a lever device (7), which is itself constrained to rotate with the drive shaft (6) of the control device. Application to medium- and high-voltage circuit breakers.
