Features: This book introduces high-voltage switchgear and its technological innovations both domestically and internationally. In the field of high, ultra-high, and extra-high voltage, it covers SF6 circuit breakers and SF6 gas-insulated switchgear (GIS). Regarding high-voltage circuit breakers, in addition to discussing advancements in air-blast circuit breakers, it emphasizes the thermal expansion circuit breakers. For ultra-high and extra-high voltage, it focuses on 550kV single-pole and 1100kV double-pole SF6 circuit breakers. In terms of GIS, apart from introducing 1100kV GIS, it highlights the three-phase common cylinder, composite, and miniaturization of GIS. In the medium-voltage product field, it emphasizes vacuum circuit breakers with magnetic force operating mechanisms, various arc-quenching principles of SF6, and self-energy SF6 circuit breakers. It also provides a dedicated introduction to load switch combinations—current-limiting fuse combinations for urban power networks. The book also covers prefabricated substations and discusses the characteristics of rural power networks and the special requirements for high-voltage switchgear. This book is a valuable reference for engineering technicians in power design departments, high-voltage electrical research and manufacturing sectors, as well as faculty and students in relevant disciplines of higher education. It is particularly useful for planning, product selection, technical exchanges, staying updated on the latest advancements and dynamics in product technology and innovation.
