SF6 Hochspannungs-Lastschalter

SF6 Load Switch Genaral FL(R)N38-12 SF6 load switch is a 10KV high voltage switch equipment,which is researched and designed by ourselves,its performance meets or exceeds the country standerd.It widely used in 10KV transformer system, usually worked as the inlet and outlet main cable switch of RMU,outdoor cable distribution boxes,transformer chamber and etc. 1)Switch case is made of reinforced epoxy resin which casting under vacuum, there is 1.4 bar SF6 gas inside as insulating and arc-extinguishing material. 2)It has two fracture,three position rotating moving contact,switching-on ,opening,earthing 3)An explosion relief channel in the back,to protect operators from high temperature and high pressure 4)It is small in size,column order,easy install 5)With an able-see window,could observe working state 6)Can install barometer and pressure node 7)Secrity and stability during operation,maintenance during the life time Specification ItemsUnitParaterFLN38FLRN38rated voltageKV12rated currentA630125main circuit rated short time current/lasting timeKA/S25/2ground loop rated short time current/lasting timeKA/S20/2rated peak withstand and short circuit making currentKA/S31.5125rated loading breaking currentA630Rated closed switch-off currentA6305%rated loading breaking currentA31.5Rated cable charging currentA10rated breaking no-load transformer capacityKVA1250rated transfer breaking currentA—1700rated short circuit breaking current insulation levelKA—31.5fust link rated maximum currentA—1251min power frequency withstand voltage phase-groundKV42breaker gapKV48lightning impulse withstand voltageKV75breaker gapKV85main circuit,ground loop mechnical lifeTIMES3000/2000SF6 rated pressureMpa0.04
