A ring network type prefabricated substation according to claim 1, characterized in that, The lower surface of the movable seat (201) is provided with a support mechanism (400), which is used to lift the movable seat (201) upward during the process of the movable wheel (203) retracting into the rectangular cavity. The support mechanism (400) includes four vertical sealing cavities (401) arranged in a rectangular array inside the movable seat (201), and four piston plates (402) respectively slidably disposed on the inner wall of the four vertical sealing cavities (401). The lower surface of the piston plate (402) is fixed with a rectangular support leg (403), and the inner bottom wall of the vertical sealing cavity (401) is provided with a rectangular hole (404) extending to the lower surface of the movable seat (201) and slidably connected to the outer surface of the rectangular support leg (403).

9. A ring network type prefabricated substation according to claim 8, characterized in that, The support mechanism (400) further includes four telescopic inflatable airbags (405) fixed in a rectangular array on the top wall of the rectangular cavity. The four telescopic inflatable airbags (405) are used to inflate the interior of the four vertical sealed cavities (401) respectively. The extrusion ends of the four telescopic inflatable airbags (405) are fixedly connected to the upper surface of the rectangular plate (202).

10. A ring network type prefabricated substation according to claim 9, characterized in that, The inner top and bottom walls of the telescopic inflatable airbag (405) are fixed with a return spring (406), and the end of the telescopic inflatable airbag (405) is provided with a connecting tube (407) extending into the vertical sealing cavity (401).
