It is divided into three function compartments, high voltage compartments, transformer compartment and low voltage compartment. Both high voltage and low voltage compartments are provided with all functions, the primary power supply system on high voltage side can be configured in various power supply methods, such as ring net power supply, terminal power supply, power supply with double supply. High voltage metering instrument can also be installed on high voltage side to satisfy the requirements for high voltage measurement. For transformer compartment, S9, S11 series low loss oil immersed transformer, and SC(B)9' SCR9' SC(B)10' SCR10 series dry transformer are available, and the transformer compartment is equipped with self-start forced air-cooling system and lighting system. The low voltage compartment can be equipped with panel or cabinet type structure based on customer's requirements, and has various functions including distribution for drive power, power distribution for lighting, compensation of reactive power, metering of electricity energy, and measurement of electricity consumption to meet various demands of customers and provide customers with convenient management and high quality in terms of power supply.High voltage compartment is designed with compact structure and interlock function of "five preventions" to completely protect from mis-operation. Upon customers request, the transformer can be equipped with guide rail for convenient access through the gates on both sides.Main technical data1.Load switch technical dataNumberItemUnitFN12-12Load switchFZN21-12Vacuum load switch1Rated voltageKV102Maximum working voltageKV123Rated frequencyHZ504Rated currentA6305Rated breaking currentA6306Rated thermal current (Virtual value)KA/S20/220/47Rated dynamic currentKA50508Short-circuit current (Peak value)KA50509Full-load breaking timestimes201000010Mechanical lifetimes200010000111-min power frequency withstand voltage (phase to earthing)KV424212Lightning impulse withstand voltage(phase to earthing)KV75752.High voltage fuse technical dataNumberRated voltage(KV)Rated current(A)Breaking current(KA)Fuse rated current(A)British typeDomestic typeSDL*J124031.56.3,10,16,20,25,31.5,40SFL*JXRNT-121210031.550,63,71,80,100SKL*J1212531.525TypeRelease formRelease rated current (A)Making-breaking capacityKA (AC380V)DW15-630thermo electromagnetic315,400,63040DW15-1000electronic form630,800,100050DW15-1600160050DW15-25001600,2000,250060CW1-2000Intelligent form630,800,1000,1250,1600,200065(80)CW1-32002000,2500,3200100Note: According to whether install striker or not.
