The invention discloses a dynamic seal transmission structure and a combined electric appliance gas insulated switchgear, and relates to the technical field of high-voltage power transmission equipment. The device comprises a cabinet body isolation plate and a torsion transmission disc, wherein the middle part of the torsion transmission disc is provided with a spiral isolation pad made of a soft elastic material; the outer circumference of the spiral isolation pad is hermetically connected with a hard frame; the spiral isolation pad is folded in the radial direction to form a spiral gap; the spiral-shaped gap is used for accommodating tensile deformation generated by the side wall when the spiral-shaped isolation pad axially rotates; a transmission part is axially arranged in the middle of the torsion transmission disc in a penetrating mode, and one side of the transmission part is connected with an operation knob; and the transmission part is connected with a transmission coupling part at the other side of
