Outdoor AC Boundary Vacuum Load Switch

outdoor AC boundary vacuum load switch  FZW28-12F ( FFK ) type user dividing vacuum load switch ( referred to as the demarcation switch ) used in outdoor column installed occasions,Website:http://www.qdyonghuaxu.com, has manual and electric operation function. The switch body is introduced by Toshiba Co of Japan VSP5-12 technology ,the switch is a maintenance-free load switch . Vacuum interrupter and SF6 gas on ground and inter phase insulating medium.  This product conforms to GB3804 AC high voltage load switch: " GBT11022 " and " high voltage switchgear and control gear standards common technical requirements " .  FZW28-12F type dividing vacuum load switch ( FZW28-12 switch and FDR-01 controller ) with fault detection function, protection and control functions and communication functions, installed in the 10kV overhead transmission line, can realize the automatic removal of single-phase grounding fault and automatic isolation of inter phase short circuit fault . Mounting points for 10kV distribution line user line responsibility demarcation point, also can be applied to meet the requirements of the branch line junction.No.NameDate1Method of operationManual or automatic (electromagnetic)2Rated valueRated voltage12kVRated current630ARated short-time withstand current(4S)12.5     16     20Rated  closing short-circuit current(peak)31.5     40     50Rated frequency50HzOperating voltageAC220V(80%~110~)3Power frequency withstand voltage(1min)On the ground42kVAlternate with42kVFracture48kVTwo of2kV4Impulse withstand voltage(peak)On the ground75kVAlternate with75kVFracture84kV5Net weight185kg6SF6 gas rated pressure0 psig concentration was above 93%7Operationg handle power determination100~400N8Main loop resistance≤ 500 μ Ω9(one)closing operation184~220V1 time off 120~180 ms(220V) 400 ms the following(184V) 2 bounce time is not over 10ms 3 absorb and current (peak) and A following 4 maintain current is not more than 0.45AThe minimum switching voltage120~160V(two) tripping operation184~220V1 time gate The following 1.5s 2 different period of time   under 30msMinimum maintain suck and voltage65~85V10Isolating fracture and the vacuum arc-extinguishing chamber and operation time difference10±2 ms11Tightness test (leak)0.2 Mpa gauge without gas leakAge12Vacuum interrupters contact distance7~9 mm13Vacuum interrupters contact distance3~3.5 mm14Isolating distance25~30 mm15Isolating distance6~13 mm
