Vs1 - 12 Series Indoor High-Voltage Vacuum Circuit Breaker

GENERALZN63S (VS1) - 12 series indoor high-voltage vacuum circuit breakers (hereinafter referred to as "circuit breakers") are indoor high-voltage switchgear with a rated voltage of 12kV and three-phase AC 50Hz. They are used as protection and control units for power grid equipment and power equipment of industrial and mining enterprises. It is applicable to places requiring frequent operation under rated working current or breaking short-circuit current many times.The circuit breaker complies with technical standards such as GB / T1984 - 2003 and DL / T402 - 2007.MODEL DESCRIPTIONZ:     Vacuum Circuit BreakerN:    Indoor63:   Design Serial NumberS:     Three Phase12:   Rated VoltageFUNCTIONAL FEATURES☆ High service life: the mechanical life is 30000 times, the number of full capacity short-circuit current interruptions are 50 times, and frequent operation or multiple circuit current interruptions can be carried out within the working current range.☆ Commercial reliability: it is suitable for reclosing operation with various characteristics and can be used instead of imported VD4.☆ Full working condition: vertical insulating cylinder is used to prevent various special environmental impacts.☆ Maintenance-free: adopt solid insulation structure to integrate solid sealing pole.☆ Complete functions and multiple uses: it can be installed in a fixed manner, can also be moved for use, and can also be installed on the frame.☆ Standardized design: good interchangeability and versatility, especially suitable for kyn28 (gzs1) indoor central high-voltage switchgear..MAIN TECHNICAL PARAMETERS  No.ItemUnitData1Rated frequencykV122Rated Insulation Level1 min Power Frequency Withstand Voltage (effective value) 45 (Fracture 48)Lightning Impulse Withstand Voltage 75 (Fracture 85)3Rated FrequencyHz504Rated CurrentA630, 12505Rated Short-Circuit Breaking CurrentkA20;25   31.5   406Rated Short-Circuit Closing Current (Peak Value)kA50;63    80   1007Times of Rated Short-Circuit Breaking Current Times50, 308Rated short-time withstand current and durations49Mechanical LifespanTimes3000010Rated Operating Order O-0.3S-C0-180S-CO11Rated Short-Circuit Breaking Current Breaking timesTimes5012Operating Mechanism Rated Closing VoltageVAC110/220 DC110/22013Operating Mechanism Rated Opening VoltageVAC110/220 DC110/22014Contact Distancemm11 +/- 115Overtravel (crimping length of contact spring)mm3(+1.0, -0.5)16Three Pole Closing and Opening Non-synchronismms≤217Contact Closing Bounce Timems≤218Average Opening Speedm/s0.9 ~ 1.319Average Closing Speedm/s0.4 ~ 0.820Opening Speedms20 ~ 5021Closing Speedms30 ~ 7022Main Circuit ResistanceμΩ≤50,  ≤3523Allowable Wear Cumulative Thickness of Moving and Stationary Contactmm3Note: If the altitude is over 1000m, the rated insulation level should be modified as appropriate.OUTLINE AND INSTALLATION DIMENSION/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
