3Revisiting the thermal ageing on the metallised polypropylene film capacitor:from device to dielectric film显示文摘Metallised polypropylene film capacitors(MPPFCs)are widely used in power electronics and are generally degraded by elevated temperatures.This work aims to determine the relationships between the structural changes of MPPFC and the microstructural variations of the PP film during the thermal ageing of MPPFC at 100℃ for 38 days.The capacitance of MPPFC has a slight decrease during thermal ageing.However,the breakdown voltage of the MPPFC decreases by 39.4%by the ageing.The partial discharge(PD)number of MPPFC increases linearly with ageing time.The tear-down analysis of the MPPFC reveals that the molecular structure of the PP film has not been altered but has led to molecular chain scission and the generation of some polar fragments/groups.Meanwhile,the relative permittivity of the PP films rises as the ageing time increases.Moreover,thermal ageing causes the conversion of aluminum to alumina in the metallised electrode,which is hydrophilic for polar groups and leads to an adhesion effect between the metallised electrodes and the PP film.Contact angle measurements prove that the surface hydrophilicity of the PP sample increased after thermal ageing.Therefore,the PD/breakdown voltage in the MPPFC increases/decreases due to the uneven adhesion of the metallised PP film.Yushuang He Feipeng Wang Guoqiang Du Lei Pan Kaizheng Wang Reimund Gerhard Ronald Plath Pawel Rozga Pavel Trnka 2023High Voltage2023,8,2:2
