The utility model discloses a thermal-insulation and rainproof lighting linkage air inlet shutter suitable for a transformer substation. The thermal-insulation and rainproof lighting linkage air inlet shutter comprises a window frame; the window frame is divided into a left part and a right part by a window lining vertically arranged in the middle of the window frame; three glass shutters are arranged in sequence from top to bottom in each part of the window frame; a center shaft penetrates through the middle of each glass shutter; one end of each center shaft is connected with the side edge of the window frame, and the other end of each center shaft is connected with the window lining; one end, located on the window lining, of each center shaft is provided with a gear; at least two motors are arranged in the window lining; the at least two motors are respectively chained with the center shafts of the glass shutters at both sides through a chain; the glass shutters respectively consist of three layers of glass, and the three layers of glass are arranged in a step manner. The thermal-insulation and rainproof lighting linkage air inlet shutter disclosed by the utility model can be controlled to be opened and closed, and therefore the thermal-insulation effect and the rainproof effect can be exerted, and sufficient lighting can also be ensured; if the motors are connected with the control system of the transformer substation, intelligent control on ventilation can be realized.
