The present application provides a governor assembly (1), an elevator safety device, and an elevator system. The governor assembly comprises: a bracket (10); a rotatable rope sheave (34) mounted on the bracket; and a centrifugal mechanism (19) associated with the rope sheave, a plurality of centrifugal members (191) being capable of unfolding under an inertial force associated with the speed of the rope sheave; wherein, the centrifugal mechanism comprises: a plurality of centrifugal members pivotally connected to the rope sheave; and a retaining mechanism by which the plurality of centrifugal members are retained in a contraction position; wherein, the retaining mechanism is configured to retain the plurality of centrifugal members in the contraction position when the speed of the rope sheave increases to a first threshold with an acceleration smaller than a first acceleration.
