摘    要:火花检测在静电除尘中占有十分重要的地位。针对现有基于二次侧信号时域特征分析的火花判据容易产生误判与漏判的问题,提出一种基于快速傅里叶变换的火花检测方法。通过分析二次侧电流及电压采样信号在频域下的特征完成火花的精确识别。经过电场实验验证,频域特征分析法能有效克服现有火花检测判据抗干扰能力不足的缺陷,对于火花检测方法的改进具有一定的指导意义。

关 键 词:静电除尘  火花检测  快速傅里叶变换

Abstract:Abstract: Spark detection is of great importance in electrostatic precipitation. In order to solve the problem of false detection and miss detection while using the existing time-domain spark criteria based on the analysis of the secondary signal, this paper proposes a method for detecting spark based on fast fourier transform. This method detects spark precisely by analysing the frequency-domain character of the secondary signal. It is proved to have a great anti-interference performance and can help with the improvement of the method for detecting spark.
Keywords:electrostatic precipitation  spark detection  fast fourier transform
