New Type Vcb Vsg 35kv 36kv 40.5kv Vacuum Circuit Breaker

VCB-12 series solid-sealed indoor vacuum circuit breaker is an indoor high-voltage switchgear for three-phase power system with rated voltage of 12 kV and frequency of 50 Hz. It is used as protection and control appliance due to vacuum circuit breaker. The special advantages are especially suitable for frequent operations requiring rated current or multiple short-circuit currents.  VCB-12 series solid-sealed indoor vacuum circuit breakers are fixedly mounted, mainly used for fixed switchgear. The circuit breaker can be used alone or in ring power supply, box transformer or various non- power supply system.NOItemUnitsTechnical parameters1Rated voltageKV122Rated short-duration power frequency withstand voltage 42/48(Interphase, ground/fracture)3Rated lightning impulse withstand voltage 42/48(Interphase, ground/fracture)4Rated frequencyHz505Rated currentA630   1250630 1250 16002000 2500 3150630 1250 16002000 2500 31506Rated short-circuit breaking currentKA20/2531.5407Rated short-time withstand voltage 20/2531.5408Rated short circuit durationS49Rated peak withstand currentKA50/638010010Rated short circuit closing current 50/638010011Secondary circuit power frequency withstand voltage (1min) 200012Rated single / back to back capacitor group breaking currentA630/400(40kA:800/400)13Rated capacitor bank closing current 12.5 (frequency is not greater than)14Mechanical lifeKA2000015Rated current breaking times (electrical life) 2000016Rated short circuit current breaking timestimes50(40KA≤30)17Dynamic and static contacts allow wear cumulative thicknessmm318Energy storage times≤1019Contact opening distancemm11±120Overtravel 3.5±0.521Contact closing bounce timems≤2(40KA≤3)22Three-phase split/closed period ≤223Average opening speed (contacts are separated by -8mm)m/s1.2±0.224Main conductive loop resistance 0.6±0.225Main conductive loop resistanceμΩ≤50(630A)≤45(1250A)≤40 (1600,2000A)≤35 (2500A or more)26Rated operation sequence 0-0.3s-Co-180s-CoFAQ1.
