Product Description
outdoor high voltage vacuum circuit breaker  outdoor high voltage vacuum circuit breaker is three hase AC 50Hz, rated voltage is 40.5kV outdoor high-voltage electrical equipment , attached the spring operator or electromagnetic actuator can be well controlled electric opening and closing can also be Manual storage, manually open and close. Design performance meet GB1984-89; national standards, and meet the IEC-56 ; International Electro-technical Commission standards. ZW7-40.5 series vacuum circuit breaker is mainly used for outdoor 35kV power transmission system control and protection also applies to urban and rural power distribution networks and industrial and mining enterprises in the normal operation and short circuit protection purposes. The overall structure of the insulator pillar product type; built vacuum interrupter type on the vase, porcelain vase for the next pillar vase. For frequent operation place. And has good sealing, anti-aging, high pressure, no burning, no explosion, long life, convenient installation and maintenance features.ItemUnitsValueRated voltageKV40.5Rated insulation level1min power frequency withstand voltageDry95Wet80Lighting impulse withstand voltage(peak)185Rated currentA1250,1600,2000Rated short-circuit breaking currentKA20,25,31.5Rated operating sequenceO-0.3s-CO-180s-CORated short-circuit breaking current breaking timestimes20Rated short- circuit closed current (peak)KA50,63,80Rated peak withstand currentRated short-time withstand current20,25,31.5Rated short-circuit durations4Average opening speedms1.5±0.3Average closing speed0.6±0.3Contact closing bounce durationms≤ 5Three phase closing and opening synchronism≤ 2Closing time≤ 90Opening time≤ 60Mechanism lifetimes10000Rated operating voltage and auxiliary loop rated voltageVDC110/220AC110/220Phase loop DC resistance (without current transformer)µ Ω≤ 100Permitted accumulate wear-thickness of dynamic and static contactmm3Weightkg800
