SF6 switch main advantage is three or four loops, in SF6 gas CCP box, small, free from outside influence climate, but SF6 gas ozone-depleting resources, do not meet environmental trends. Its current breaking capacity between 2000 ~ 3500A. SF6 load switch currently requires users to engineering design in general have zero gauge pressure, breaking the normal load capacity of Shijiazhuang high voltage load switch, even to when SF6 gas leak occurs, but also has a certain load breaking capacity. Gas and compressed air load switch difficult than breaking transfer current 2000A, it is recommended to use high-voltage load switch Shenyang in the following engineering capacity 500kVA transformer, the transformer capacity above 500kVA, we recommend using a vacuum load switch. Vacuum load switch is a vacuum interrupter, and moving contacts are in the arc chamber, the vacuum interrupter breaking ability, stable performance, no lights the fire and explosion hazards, and can be frequent operation, maintenance-free, not only can open off transfer current can also transfer current reaches 2880A breaking above. Within N12-12D / 630-20 type indoor AC high voltage load switch is rated voltage 12KV, rated frequency 50HZ three-phase high-voltage switchgear high voltage switches for the division and load current, loop current Baotou high voltage load switch, load transformer and cable charging current, closing short-circuit current. Equipped with grounding switch load switch that can withstand short-circuit current Chifeng high voltage load switch |.
