An automatic control method and system for a moisture-proof and heat-dissipation type electric energy metering box

Abstract

The application belongs to the technical field of power systems, and specifically relates to an automatic control method and system for a moisture-proof and heat-dissipating electric energy metering box. The method comprises the following steps: obtaining an equivalent dielectric constant sequence; identifying a potential starting position of microcosmic adsorption of water molecules on the surface of an insulating component. A capacitance mutation prediction value corresponding to the potential starting position is calculated through a capacitance model. The capacitance mutation prediction value is matched with data in a historical database, and a clustering algorithm is used to determine whether the potential starting position has a condensation risk. If the potential starting position has a condensation risk, a moisture-proof intervention unit is started, and the equivalent dielectric constant of the potential starting position is stabilized in a preset steady state interval through closed-loop regulation. The equivalent dielectric constant data stabilized in the preset steady state interval is supplemented to the historical database as an effective sample, and the clustering algorithm is iteratively optimized. The application can realize early identification and accurate control in the initial stage of macroscopic condensation, and significantly improve the precision of moisture-proof control of the electric energy metering box.
