| Summary: | The opening and closing speeds of GIS switches are relatively fast, so it is difficult to judge the possible defects of the mechanism through manual observation. In order to quickly and accurately identify the switch state or defect type, this paper designs a GIS switch state detection platform based on image recognition technology and wireless power transfer (WPT) technology. The wireless charging capability creates the conditions for the platform’s versatility and portability to some extent. This paper mainly analyzes the stability and anti-offset of the WPT system. According to the theoretical analysis, the efficiency of the wireless charging system is more stable than that of the traditional LCC WPT system under the same output power. Within the offset distance of 0.11 m, the efficiency can be maintained at about 92%, with almost no change. The results show that the proposed method is effective. |
