State Grid Hebei Economic Research Institute, Shijiazhuang, Hebei, 050000, China
This article introduces environmentally-friendly metal-enclosed switchgear, and comprehensively summarizes the development status, technical characteristics, technical difficulties and development trends of solid-insulated ring network cabinets and environmentally-friendly gas-insulated switch cabinets. The development status of solid insulated ring network cabinets and environmentallyfriendly gas insulated switch cabinets are reviewed, and their technical characteristics are summarized in terms of volume, structure, maintainability, safety and environmental adaptability. Focus on the analysis and study of the technical difficulties of solid insulated ring network cabinets and environmentally friendly gas insulated switch cabinets, and pointed out the partial discharge control of the surface of the insulating parts, the strengthening of the sealing, the cost control, the recycling and utilization of epoxy resin, the optimization of insulation, and the breaking capacity. The guarantee of the quality, the selection and recovery of mixed gas are their future development trends. It provides a useful reference for the development and improvement of environmentally-friendly metal-enclosed switchgear.
