IEE-Business Product Overview
Na fadi - voltage pneumatic load break switches da kuma abubuwa masu shiga muhimman kan biyu - voltage wani wurin da ya gudanar da AC 12kV, 50Hz. Wannan load break switch yana da muhimmiyar tushen fasaha da inganci. Tsarin basic form of the operating mechanism shine manual spring - energy - storage type, ko zai iya samun electromagnetic spring operating mechanism. Daga baya na gasar da ba a canza arc - extinguishing tube ba, ana iya koyar da multiple times.
High - voltage load break switch yana iya kula, cikin da ka fara, da kuma kula load currents a wurin da aka faɗa, kuma yana da kyakkyawan kula short - circuit currents da kula short - circuit currents a lokacin da aka bayyana.
Load break switches zai iya samun earthing switches. Earthing switch yana da short - circuit making capacity da ta fi load break switch, da kuma dynamic da thermal stability capability, kuma yana da mechanical interlock mai kyau da load break switch, don haka ya ƙara misoperation daga tsari.
Muhimman Tushen
Idan FKN12 - 12 load break switch yana da high - voltage current - limiting fuse (da striker) don ƙoƙarin load break switch - fuse combination, yana yi overloading da short - circuit protection ga loads (kamar power transformers). Idan one or more phases of the fuse blow, three phases of the load break switch zai kula automatically.
High - voltage load break switch yana da kyakkyawa don installation a ring - main unit switch cabinets da sauran types of switch cabinets don receiving and distributing electrical energy.
