摘要

本文介绍了一种基于TMS320c25单片机的多功能声信号分析系统，用于检测发电机定子绕组接地壁绝缘缺陷。当用振动器轻敲定子绕组时，产生包含缺陷信息的声音，由声换能器拾取并在频域进行分析。检测结果显示在液晶显示器上，并由微型打印机打印。与传统的检测方法相比，该系统具有分辨率高、结果显示实时、操作方便等优点。

Detection of defects in groundwall insulation of HV generator stator windings with a microcontroller system

In this paper, a multi-function acoustic signal analysis system with a microcontrol chip (TMS320c25) is introduced for detecting defects within groundwall insulation in generator stator windings. When the stator winding is tapped with a vibrator, a sound containing defects information is produced, picked up by an acoustic transducer and analyzed in the frequency domain. The detected results are displayed on a liquid crystal display and printed by a microprinter. Compared with conventional detecting methods, the system has advantages such as higher resolution, real time display of results and convenient operation.<>
