The invention relates to the technical field of power distribution network high voltage switchgear equipment, in particular to a dynamic repulsion disk and a repulsion mechanism using the same. When a dynamic repulsion disk is in use, the dynamic repulsion disk is fixedly connected with a transmission rod; and the dynamic repulsion disk comprises a disk-shaped skeleton, and a first dynamic repulsion coil and a second dynamic repulsion coil fixed on two sides of the skeleton axially. The dynamic repulsion disk adopts a single-disk and double-side dual-coil structure; when the dynamic repulsion disk is in use, the energized dynamic repulsion coil and the corresponding static repulsion coil generate electromagnetic repulsion to drive the transmission rod to move at a high speed; and by using the dynamic repulsion disk, the movement reliability of an operating mechanism can be improved, rapid close and cut-off of circuits can be realized, the impact on systems from an electromagnetic transient effect is reduced, and the power supply quality is improved.
