1 Scope This standard specifies the naming principle, composition and organization method of the types of high-voltage switchgear and controlgear and their complete equipment, fuse as well as enclosed busbar and its auxiliary equipment. This standard is applicable to high-voltage switchgear and controlgear and their auxiliary equipment with a rated voltage of 3.6kV or above as well as equipment under the unified management of high-voltage switch industry, such as high-voltage/low-voltage prefabricated substation. Including: - high-voltage A.C. circuit breaker (hereinafter referred to as "circuit breaker"); - high-voltage A.C. isolating switch (hereinafter referred to as "isolating switch"); - high-voltage A.C. load switch (hereinafter referred to as "load switch"); - high-voltage A.C. earthing switch (hereinafter referred to as "earthing switch"); - high-voltage A.C. contactor (hereinafter referred to as "contactor"); - high-voltage A.C. automatic recloser (hereinafter referred to as "recloser"); - high-voltage A.C. automatic sectionalizer (hereinafter referred to as "sectionalizer"); - high-voltage A.C. fuse (hereinafter referred to as "fuse"); - high-voltage A.C. load switch - fuse switchgear (hereinafter referred to as "load switch - fuse switchgear"); - high-voltage A.C. contactor - fuse switchgear (hereinafter referred to as "contactor - fuse switchgear"); - A.C. metal-enclosed switchgear and controlgear; - high-voltage/low-voltage prefabricated substation (hereinafter referred to as "prefabricated substation"); - gas-insulated metal-enclosed switchgear (herein after referred to as "GIS"); - hybrid gas insulated switchgear (hybrid gas insulated switchgear "H-GIS"); - conventional air insulated switchgear (C-AIS); - rigid gas-insulated metal-enclosed transmission line (GIL); - metal-enclosed busbar; - cable distribution box; - operating device; - vacuum arc extinguishing chamber; - auxiliary equipment. Note 1: The switchgear based on tank-type circuit breaker is referred to as H-GIS while the switchgear based on knob-type circuit breaker C-AIS. Note 2: The auxiliary equipment mainly refers to electromagnetic lock, mechanical lock, charged display device, electronic device, connector base, sulphur-hexafluoride aeration and recovery device and auxiliary switch which are provided for switchgear to form independent products. The organization of the types of other auxiliary equipment under high-voltage switch industry may refer to this standard.
