摘要: 针对GIS隔离开关存在的安全隐患,通过分析GIS隔离开关的机械结构,搭建试验平台,建立电机功率与GIS触头位置的物理关系,提出一种基于多窗口斜率的啮合点识别方法,实现功率曲线分段,进而根据经验比对实现GIS隔离开关机械状态的诊断。在线监测案例证明,在工程中可以通过电机功率实现GIS隔离开关机械状态与分合位置的准确判断。

Abstract: To address the safety hazards of GIS disconnector, the physical relationship between motor power and GIS contact position is established by analyzing the mechanical structure of GIS disconnector, and test platform is built. When there is a jamming defect, the power amplitude of the entire process increases. A meshing point identification method based on multi-window slope is proposed to realize the segmentation of power curves, and then the diagnosis of the mechanical state of GIS disconnector is realized according to empirical comparison. The online monitoring case proves that the accurate judgment of the mechanical state and the opening and closing position of GIS disconnector can be realized by motor power in engineering.

Key words: gas insulated switchgear(GIS) disconnector, mechanical defects, motor power, engineering application
