Intdoor Load Break Switch Earth Load Switch

PRODUCT DETAILShigh voltage load switch -- fuse combination Description:        FKN12A-12D/T630-20 indoor high voltage pneumatic load switch-fuse combination (hereinafter referred to as FKN12A-12D load switch) is three-phase high voltage switchgear with rated voltage of 12kV and rated frequency of 50Hz, which is used for the separation and combination of load current, closed-loop current, no-load transformer and cable charging current. Turn off the short circuit current. Load switch equipped with ground switch can withstand short circuit current. FKRN12A-12D/T125-31.5 AC high voltage load switch-fuse combination is indoor high voltage switchgear combined with FN12A-12D load switch and Sport LAJ-2 (XRNT-10) high voltage current-limiting fuse. It can reliably turn on any current up to the short-circuit current, the load switch turns on the working current, the fuse turns on the short-circuit current, and the fuse turns on any overcurrent between the working current and the full short-circuit current. At the same time, the fuse switches off the load switch through its impinger. TECHNICAL PARAMETER  The technical parameters of the form are for reference only. Customized products can consult online customer service!No.projectunitsFKN12A-12DFKRN12A-12D1The rated voltageKV12122Rated frequencyHz50503Rated currentA6301254Rated insulation level1min power frequencywithstand voltageAgainst the ground, phaseKV4242 The isolation of fractureKV4848 Lightning shock withstandvoltage (peak)Against the ground, phaseKV7575 The isolation of fractureKV85855Load switchKA20- Grounding switchKA20206Load switchS4- Grounding switchS227Rated short circuit closing current (peak)KA50-8Rated breaking currentActive load breaking currentA630- Closed-loop breaking currentA630- 5% active load breaking currentA31.5- Cable charging currentA10- Turn off the no-load transformer capacityKVA125012509Rated short circuit breaking current (current limiting fuse)KA-31.510Rated transfer currentA-120011Mechanical lifenext2000200012Impactor outputs energyJ-1+0.5   serial numberThe name of theunitsdata1Fracture frommm≥1752Interphase center distancemm210±23Interphase air gapmm≥1254tripmm210±45Overtravelmm≥406The three-phase switch is not at the same timems≤107The three-phase switch is not at the same timems≤58Inherent tripping time of shunt tripms40~659Main circuit resistanceμΩ≤130THE USE OF CONDITIONSAir temperature: -25ºC~+40ºC;Altitude: not more than 1000m;Relative humidity: daily mean no more than 95%, monthly mean no more than 90%.Earthquake intensity: no more than 8 magnitudes;Installation place: no fire, explosion danger, chemical corrosion and violent vibration place;Filth level: 2.RELATED PRODUCTS        COMPANY INFORMATION    Zhejiang ZheGui Electric Co., Ltd established in 2013.
