摘要
Abstract
GIS disconnector plays a vital role in power system,but the problem of not opening and closing to the end will threaten safety of the system.The information inside the compartment which is reflected by the traditional status detection method is limited.In this paper,a new method based on electromagnetic transient processes is proposed.By utilizing the electromagnetic transient information generated during the opening and closing process of GIS disco-nenctor at live condition and through analyzing the relationship between the start and stop time of the electromagnetic transient signal and the position of the stationary and moving contacts of the disconnector,the status of the moving and the stationary contacts within the GIS disconnector compartment is inverted.At the same time,a method for ex-tracting high-frequency electromagnetic transient signal features at a low sampling frequency is proposed,and corre-sponding acquisition device is developed.This method not only significantly reduces data collection requirements,but also successfully verifies the opening and closing positions of GIS disconnector.Finally,the effectiveness of the method proposed in this paper is verified by experiment.关键词
