Cabinet body structure of high-voltage power distribution cabinet

The utility model relates to the field of power distribution cabinets, and discloses a cabinet body structure of a high-voltage power distribution cabinet, which comprises a supporting base, a power distribution cabinet body is arranged on the top surface of the supporting base, ventilation grid meshes are fixedly mounted on the left side and the right side of the supporting base respectively, and a rectangular through hole I is formed in the top surface of the supporting base; a second rectangular through hole corresponding to the first rectangular through hole is formed in the bottom face of the power distribution cabinet body, when rainwater enters the supporting base through the ventilation grid net and continuously rises, the water level sensor outputs a voltage signal to the PLC, the PLC feeds back a signal to the circular electromagnetic block so that the circular electromagnetic block can be powered off, and the rainwater can be discharged through the ventilation grid net. And when the circular electr
