摘要
Abstract
Due to the closed structure and complex components,the determination and location of the partial discharge (PD) defects on composite apparatus have always been difficult problems.Based on the testing method of ultrasonic and ultra high frequency (UHF),this paper introduces a new method of bridge connection by capacitive arm in the high frequency (HF) to detect the PD defects.By using the variety of testing methods and making experiments after dismantling,this paper carries out a detailed analysis of suspension discharge case in a 220 kV composite apparatus,the analysis results show that:the method of bridge cormection by capacitive arm in HF can effectively assist to determine and locate the PD defects;by verifying the variety of testing methods mutually,the accuracy of PD determination and location can be improved;by comprehensively using the ultrasonic-ultrasonic location method and combining ultrasonic and UHF location method,defect interference ehmination and precise location can be realized,and the efficiency of equipment maintenance can be effectively improved.关键词
