Abstract

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
