Application and analysis of super dual hydrophobic and super self-cleaning coatings in moisture and condensation prevention of power equipment
This article studies the application and effectiveness of ultra double hydrophobic and ultra self-cleaning coatings in moisture and condensation prevention of power equipment.Power equipment is susceptible to moisture and condensation in high humidity environments,leading to issues such as reduced insulation performance,corro-sion,and pollution flashover.Due to the limitations of traditional moisture-proof measures,this study designed an ultra double hydrophobic and ultra self-cleaning coating based on the"lotus leaf effect",which effectively prevents moisture accumulation by forming a superhydrophobic and superoleophobic surface.Through coating tests on trans-formers,switchgear,and insulators,the hydrophobicity,anti condensation,and anti pollution flashover perform-ance of the coating were verified.The experimental results show that after coating treatment,the surface contact an-gle of the equipment is greater than 150 ° and the rolling angle is less than 10 °,significantly improving the mois-ture-proof effect;In high humidity environments,the condensation time of equipment exceeds 24 hours,while un-coated equipment condenses within 2 hours.The coating increased the insulation resistance of the equipment by a-bout 200％and the pollution flashover voltage by about 35％.
