Abstract
Abnormal vibration sounds often occur in the operation of high-voltage power equipment. The main reason is that the busbar joints, insulator fixtures and other parts are caused by electromagnetic force due to loosening of the screw. In order to find the fault point quickly, it is necessary to locate the fault location of high-voltage equipment in operation. Acoustic wave fault location technology for portable high-voltage equipment can accurately measure the location information of abnormal sound fault point by using pickup electret and ultrasonic distance sensor. After practical use, it meets the requirements of patrol inspection and detection of power supply companies. It is of great significance to improve rapid maintenance and ensure power supply.
