The invention provides a heat dissipation system for a switch cabinet of a transformer substation, and belongs to the technical field of transformer substations. The heat dissipation system comprises a cabinet top cooling fan assembly, a rear cabinet door air inlet assembly, an in-cabinet switch interlayer front sealing plate and an in-cabinet flow guide fan assembly. According to the invention, air in the cabinet is exhausted from bottom to top through the cabinet top cooling fan assembly under the action of the cabinet top cooling fan assembly and the cabinet interior flow guide fan assembly, air outside the cabinet enters the cabinet through the rear cabinet door air inlet assembly, and due to the influence of a switch interlayer front sealing plate in the cabinet on interlayer air flowability, the switch cabinet can be filled with air outside the cabinet quickly. According to the invention, air flows along a fixed direction in a relatively long and narrow area in the switch cabinet by utilizing the flow g
