A repair device for burnout of a stator iron core in a giant hydraulic turbine generator, and a repair method thereof are provided. The repair device includes toothed plates, ventilation slots, binding holes, ventilation holes, and binding cables. Each of the toothed plates is matched with a burnout area in the middle of the iron core, such that two ends of the toothed plate are in contact with plate assemblies. The binding cables rotatably pass through the binding holes and are pulled tightly to bind the toothed plates and coil bars into an integral structure. The present disclosure solves the problem of influence on the power generation benefit during the flood season due to long re-lamination cycle after burnout of the middle of the stator iron core of the hydraulic turbine generator.
