Indoor Vacuum Circuit Breaker (12kV,24kV)

VD4 series high-voltage vacuum circuit breaker is a kind of indoor high-voltage switch equipment with 50/60Hz three-phase alternating current and 1217.5//24kV rated voltage, which combined the technique of the ABB Corporation in Switzerland and domestic development state and manufacturing capability. The general framework of this product is taken the form combined the front body and operation system into one.Because it adopted the composite insulated material, there is no pollution and explosion danger, the insulation level is high.Technical parameterSerial numberItemUnitData31.5kA40kA50kA1Rated voltagekV12/17.5/242Maximum working voltagekV12/17.5/243Rated currentA1250,16002000,25001250,16002500,31501250,250031504Rated short-circuit break currentkA31.540505Rated short-circuit close current (peak value)kA801001256Rated peak value withstand currentkA8010012574S Rated little withstand currentkA31.540508Rated in sudation levelIndustrial frequency withstand voltagekV45(fracture 84)/55/60Thunder impulse withstand voltage75(fracture 84)/95/1259Rated operation orderOff-0.3S on and off-180S-on and off10Mechanical life-spanTimes1000011Rated short-circuit current break and close timeTimes5012Speak and move organization amount equal to the voltage of the floodgate (DC)V110,22013Speak and move organization amount assign the current of the floodgate (DC)V110,220
