Scope

This standard specifies the model naming principles, composition and preparation methods of high-voltage switchgear and supporting equipment. This standard applies to high-voltage switchgear and supporting equipment with a rated voltage of 3.6kV and above. Also suitable for high voltage/low voltage prefabricated substations. Including: 　——AC high-voltage circuit breaker; 　——AC high-voltage isolating switch; 　——AC high-voltage load switch; 　——AC high-voltage grounding switch; 　——AC high-voltage contactor; 　——AC high-voltage automatic recloser; 　——AC high-voltage automatic Segmenter; 　——AC high-voltage load switch-fuse combination appliance; 　——AC high-voltage contactor-fuse combination appliance; 　——AC metal-enclosed switchgear; 　——High-voltage/low-voltage prefabricated substation; 　——Gas insulation Metal-enclosed switchgear (enclosed combined electrical appliances); 　——Compound combined electrical appliances; 　——Open combined electrical appliances; 　——Operating mechanism; 　——Vacuum arc extinguishing chamber; 　——Supporting equipment, etc. Note: Supporting equipment mainly refers to: electromagnetic locks, mechanical locks, live display devices, terminal blocks, sulfur hexafluoride inflators and recovery devices, auxiliary switches, etc. that constitute independent products and are used for various types of switch equipment. The model preparation of other auxiliary equipment related to high-voltage switchgear can be determined with reference to this standard.
