Zw20 12kv Vacuum Interrupter for Vacuum Circuit Breaker

PRODUCT DETAILS   ZW20-12 outdoor AC HV vacuum circuit breakerDescription:          ZW20-12 outdoor AC HV vacuum boundary circuit breaker (hereinafter referred to as the boundary circuit breaker) is one of our new products. Boundary circuit breaker is a multifunctional intelligent device with the function of vacuum breaker, vacuum load switch, recloser, sectionalized four switches. The main configuration consists of vacuum breaker, CH-40 controller, external voltage transformer (Note: distribution automation line ring network available in bilateral PT) three parts. Products are widely used in 10kV, 13kV city, rural power grid space ring network for disconnecting switch, contact switch, automatic switch device which can implement the ring deployment line load. It can be used as a boundary switch (commonly known as a watchdog) in the branch line of power supply, used as reclosers and sectionalizes in feed overhead distribution network. Boundary circuit breaker with remote management pattern protection and control functions and communication functions. Reliable detection in judgment, mA level zero sequence current and short circuit current between phases, realize the automatic removal of single-phase grounding fault and phase to phase short circuit fault.        The main switch is vacuum arc and insulation adopts SF6, N2 mixed gas. The case introducing of Japan, Germany French gas sealing, explosion-proof, insulation system technology, the overall excellent sealing performance. Inside s filled with SF6, N2 mixed gas which does not leak, not affected by the external environment. The spring operating mechanism with miniaturization and performance optimization design, action reliability is much higher than the traditional spring mechanism.   TECHNICAL PARAMETERNo.nameunitsdata1The rated voltagekV122Rated frequencyHz503Rated currentA6304Rated short circuit breaking currentkA255Peak rated closing currentkA506Peak rated dynamic stable currentkA5074S heat stabilized currentkA258Rated sequence of operation minute-0.3sOr points-180sOr points9Rated energy storage motor voltageVAc22010Maximum/minimum energy storage motor voltageVAC242/18711Rated closing operating voltageVAc22012Maximum/minimum closing operating voltageVAC264/14313Rated switch operating voltageVAc22014Maximum/minimum switching operating voltageVAC264/14315Not at the same timems≤216The switch is divided at different timesms≤217SF6 gas pressure rating (gauge pressure)Mpa0.0118Rated short circuit current breaking timestime3019Mechanical lifetime10000THE USE OF CONDITIONS 1.Altitudes:2000 meters2.The environment temperature:-30ºC-+55ºC outdoor; the highest annual average temperature 20 ºC, the highes: daily average temperature 30ºC3.Relative humidity: 95% (25ºC4.Seismic capacity: horizontal ground acceleration 0.3g, vertical ground acceleration 0.15g, at the same time duration of three sine waves, a safety factor of 1.675.Earthquake intensity: 7 degrees6.The maximum daily temperature difference: 25 ºC7.The intensity of sunshine (wind speed 0.5m/s): 0.1W/cmi8.The maximum wind speed: 34m/s9.The maximum ice thickness10.Installation position: outdoor, the 10kV overhead line responsibility demarcation point11.Grounding: neutral non-grounding, arc suppression coil grounding, and low resistance groundingCOMPANY INFORMATIONZhejiang ZheGui Electric Co., Ltd established in 2013.
