This paper proposes a next-generation solid-state switchgear system that leverages wide-bandgap semiconductors, artificial intelligence and wireless connectivity to redefine conventional grid protection and control mechanisms. The proceedings of the 10th Frontier Academic Forum of Electrical Engineering (FAFEE2022) (FAFEE 2022) Part of the book series: Lecture Notes in Electrical Engineering ( (LNEE,volume 1054)) In the background of modern distribution model, people put forward higher requirements for the power system. It is an intelligent, high-end, and compact high-voltage switchgear solution that integrates four functions: protection, measurement & control, intelligence, and switching. It supports both remote and local electric operation, reducing reliance on specialized expertise. The design eliminates mechanical contacts using high-speed Si C-based. Dawei Zhang, Xinkang Yang*, Aifeng Sun, Zhikai Niu, Yizhi Wang, Jiajian Wang, Jian Wang State Grid Anyang Power Supply Company, Anyang, Henan, China *Corresponding Author As the core power transmission and distribution equipment in the power system, the condensation problem of high-voltage. For this reason, based on taken present situation of traditional switchgear and the current technical requirements for switchgear into account, a new reliable and safe modular high voltage switchgear design method is presented in this paper, which can reduce the failure rate of switchgear and.
