Chemical Composition of High-voltage Insulator Contamination and Detergency Mechanism of the Electrified Detergent for Degreasing Insulators
摘要
Abstract
We deeply analyzed the composition of the contamination of natural polluted high-voltage insulators by scanning electron microscopy（SEM）,Fourier transform infrared（FTIR）,x-ray diffraction（XRD）,x-ray fluorescence（XRF）,and ion chromatography.To study the detergency mechanism of the electrified detergent for degreasing high-voltage insulators,we investigated the forces of interaction between ceramics insulators and natural pollution and the surface tension of the electrified detergent and high-voltage insulator by contact angle and surface analysis methods.Moreover,we calculated the adhesion power,spreading factor,and wet power by Young＇s and surface energy equations.The result shows that the van der Waals plays an important role in the forces,but no hydrogen bond is formed.The electrified detergent has a lower γ.The result of WaWiSw/s≥0 shows that the electrified detergent has a self-wetting and self-spreading effect on the high-voltage insulator contamination.With the effect of the electrified detergent,the van der Waals of interaction between ceramics insulators and natural pollution decreases.So the contamination can fall off from the high-voltage insulator.This will provide a theoretical basis for development of new insulator cleaning agents.关键词
