Abstract (en)

[origin: CA2769125A1] The invention relates to an on-load tap changer having an energy storage device, by means of which an output shaft is rotatable in spurts. According to the invention, in addition to the actual energy storage spring or the actual energy storage springs, at least one further spring is provided, which absorbs/releases energy after the activation of the energy storage mechanism, whereby the torque curve can be optimised.
