ABSTRACT

Outdoor distribution equipment in the hot and humid climate zone is exposed to insulation failure and corrosive damage caused by condensation for a long time. Traditional box designs have systemic deficiencies in sealing continuity, ventilation drive capacity, and protection of key components, and cannot adapt to the double superimposed conditions of high negative pressure difference and high absolute humidity throughout the year in this climate zone. Starting from the thermodynamic formation mechanism of dew point temperature difference, this paper analyzes the intrinsic connection among the sealing leakage path of the box, the dead zone of the ventilation duct, and the hydrophilic failure on the surface of the insulating parts, and proposes structural optimization schemes for systems such as labyrinth composite sealing, hot-pressure-driven vertical duct, nano-hydrophobic coating treatment, and active temperature and humidity early warning linkage. The optimization effect is verified and analyzed through engineering practice cases.
