| Abstract: | The discharge of gas insulated switchgear(GIS) equipment can cause flashover discharge fault.In order to accurately locate the discharge point of flashover fault,an ultrasonic detecting method is proposed based on piezoelectric composite sensors by analyzing the characteristics of flashover discharge in GIS.In addition,the conclusion of ultrasonic wave propagation characteristics and laws is drawn by taking experimental study and theoretical analysis.From the engineering applications,detecting system based on ultrasonic is designed.Measurement results demonstrate that the system based on ultrasonic can accurately locate flashover fault and alarm in time,which provides reliable protection for the safe operation of transmission lines. |
