摘　　要：气体绝缘金属封闭开关设备(GIS)是电网中的重要设备之一,其机械缺陷是导致电网运行事故的主要因素。为完善GIS机械运行状态检测技术,提出了一种基于振动信号的GIS设备机械状态分析方法,在试验平台上模拟了典型机械缺陷,并采集了振动信号。通过提取分析振动信号特征值,得到了不同状态下的特征参量,为GIS机械状态辨识提供了参考依据。Gas insulated switchgear(GIS) is one of the important equipment in the power grid,and its mechanical defects are the main factor leading to power grid operation accidents.To improve the GIS mechanical operation status detection technology,a GIS equipment mechanical status analysis method based on vibration signals was proposed.Typical mechanical defects were simulated on an experimental platform and vibration signals were collected.By extracting and analyzing the characteristic values of vibration signals,characteristic parameters under different states were obtained,providing a reference basis for GIS mechanical status identification.
