Abstract：It will decline electrical equipment insulation property after condensation formed inside centralized meter box, which could initiate insulation breakdown of equipment and may result in short circuit and other faults, affecting power supply reliability and so on. In view of the condensation phenomena on centralized meter box that widely occured in coastal areas, the cause of condensation is analyzed, heating dehumidification technology, condensing dehumidification technology used in centralized meter box is compared, and anti-condensation measures are proposed. Finally, the dehumidification effect of the anti-condensation measures are verified. According to the practical application, this paper can provide some actual effect and guide significance for the prevention and control of damp and condensation phenomena in the centralized meter box in distribution networks.
