摘　　要：高压电气设备的绝缘性能对电力电网可靠安全稳定的运行起着至关重要的作用,而高压电气设备的局部放电指标客观反映了高压电气设备内部的绝缘状态。目前,对局部放电信号类型的智能识别越来越受到相关人员的重视,其相关技术已成为电气设备绝缘故障诊断的有效方法。该文从局部放电机制出发,对几种典型的放电类型做了相关的试验,并基于φ-q-n特征参数选择方法对相应的放电类型进行了模式识别的研究。The insulation performance of high voltage electrical equipment plays a vital role in the operation of the power grid safe and stable,partial discharge index of high voltage electrical equipment reflect the internal insulation status of the equipment.At present,the intelligent recognition of partial discharge signal types are more relevant personnel＆#39;s attention,its technology has become an effective method for insulation fault diagnosis of electrical equipment.This paper makes a series of experiment about several types of typical discharge from the partial discharge mechanism,and make a research about the pattern recognition of corresponding discharge type based on the φ-q-n feature selection method.
