摘要
局部放电超声阵列定位方法是一种将超声阵列传感器与阵列信号处理技术相结合的局放定位新方法。文章开发了一套基于圆环形超声阵列传感器的局放定位系统,首先设计研制了超声阵列传感器阵元与阵列传感器装配体,组合后可得到九元和十六元的圆环形超声阵列传感器,并据此搭建了一套局放定位实验系统;然后结合现有局放超声阵列定位方法,开展了大量的局放定位实验研究。结果表明,局放定位系统可以有效实现对局放源的空间定位,满足工程需要。
The PD ultrasonic array positioning is a new method combined by ultrasonic array sensor and array signal processing technology. This paper developed a set of PD positioning system based on a circular ring ultrasonic array sensor. Firstly, we can get nine arrays and sixteen arrays circular ring ultrasonic array sensor by assembling ultrasonic array sensor element and array sensor assembly that we designed and developed, and accordingly built up a set of PD experimental positioning system. Then we carried out a large number of PD positioning experiments using the existing PD ultrasonic array positioning methods. At last, the results from some experiments show that the positioning system is effective to locate PD source and can meet project needs.
