高压组合电器水平母线振动特性研究
Research on the vibration characteristics of the horizontal bus of gas insulated switchgear
摘要
Abstract
In gas insulated switchgear(GIS),abnormal mechanical vibration defects may occur during operation,posing significant risks to the equipment.Understanding the vibration characteristics of GIS in regular operation is crucial for operational status evaluation and fault diagnosis.Based on a vibration detection system centered around a three-axis accelerometer,this study measured vibration signals on the GIS of a 330 kV substation.Analyses of these vibrations are conducted from both time and frequency domain perspectives.The results show that the GIS surface signals can be described by radial,axial,and tangential vibrations,with the vibration characteristics depending on the measuring point's location due to different force modes.Within the same measurement plane,radial vibration amplitude decreases first and then increases from top to bottom,while tangential vibrations show the opposite trend.At the same measurement point but on different surfaces,both radial and tangential vibrations intensify closer to the busbar center,while axial vibrations exhibit a complex pattern.The vibration frequency is mainly around 100 Hz,with two distinct exceptional cases observed.关键词
