This study aims to mitigate the partial discharge at the pole-to-plate connection points in composite material towers under contaminated conditions.Through finite element simulations
current distortions at the metal plate and composite plate connection points are analyzed.Measures to enhance the current density distribution at these connection points are proposed.An integrated observation platform is developed for synchronized multi-parameter artificial contamination testing
which includes infrared observations
visible light
leakage current
and voltage measurements
to validate the efficacy of the optimization measures.The experimental results show that using parallel circular composite plates connected to metal sleeves effectively reduces the current density distortions at both the composite and metal plate connection points.Consequently
this suppresses local temperature rise and the formation of dry bands.
