摘要
Abstract
Such partial discharge detection means as ultra-high frequency and ultraviolet have some problem in de-fect localization.In this paper,a more effective ultrasonic localization detection means is selected and combined with microphone array technology and beam formation algorithm.Considering the acoustic signal characteristics of partial discharge of power equipment and also based on the characteristics of single-arm and multi-arm spiral array,the array design is optimized to form Archimedes single-arm curve and combine with the matched delay beam form-ing algorithm so to meet the needs of the present partial discharge localization scene.Further more,the acoustic imag-ing device is designed on the basis of above technology to display the distribution of sound sources in space in real time in the form of thermal efforts.Through the application in typical power equipment scenes such as transmission lines and substations,the acoustic imaging devices can clearly localize the partial discharge point,and the device,compared to such traditional detection instruments as UV imagers,has relatively higher localization accuracy,can evaluate the type of partial discharge and can provide the test basics for the subsequent equipment in operation and maintenance.关键词
