摘要：
Under the background of the global development of clean energy and the construction of a smart energy Internet, high-voltage switchgear, as one of the key devices, has developed rapidly in terms of intelligence, environmental protection, increasement in voltage levels and capacity. Firstly, this paper comprehensively introduces the overall development of China's switchgear and the latest research progress of high-voltage switchgear in common key technologies, such as arc extinguishing technology, simulation technology, intelligent technology, environmental protection technology, and process technology. In response to the new challenges faced by the design and manufacturing of high-voltage switchgear, companies at home and abroad have researched and developed the double-acting transmission system and the self-energizing arc extinguishing chamber structure, breaking through the multi-physics coupling simulation technology of switchgear breaking, temperature rise, etc. In addition, they have researched and manufactured intelligent high-voltage switchgear, environmental-friendly switchgear using SF6 mixed gas which has been applied in engineering, new insu-lating materials, near-net shape processing and other process technologies. The development trend of high-voltage switchgear technology mainly lies in the aspects of environmental protection, large-capacity breaking, high-speed breaking, metal-enclosed direct current switch, and new generation of smart switch. The development of high-voltage switchgear will also make the power grid safer, smarter, and greener. © 2021, High Voltage Engineering Editorial Department of CEPRI. All right reserved.
