| 中文摘要: |
| 我们已详细描述了一种新颖的超声自触发式局放被动定位系统的硬、软件实现[1].对声触发、在线检测的原理、实用化的时延估计方法和被动定位算法进行了初步理论探讨。本文通过实验和工业现场测试运行,证明了本系统对电力变压器(包括500kV电抗器)设备检测有许多独特的优点,具有重要的实用价值 |
| 英文摘要: |
| In our previous paper as partⅠ,a new self-trigger ultrasonic passive localization system for partial discharges and its hardware and software realization had been described. Either the principle of ultrasonic trigger and on-line test, or the useful algorithm of time delay estimation and passive localization is discussed theoretically. At last, by means of experimental and industrial operation, the system has been proved to have many special advantages, especially the important practical value in examination of electrical equipment. The system characteristics and practicable experiment results are introduced in this paper as partⅡ |
