Detailed Product Description: | Details: interrupter way: vacuum breaker Model: VS1-12/630-20 Rated insulation voltage: 12k (V) Number of poles: 3P Brand: Yunkai Mechanical life: 1 (000 times) Rated frequency: 50 (Hz) Product Certification: ISO9001 custom processing: the Product Overview VS1 (ZN63A) -12 indoor AC high voltage vacuum circuit breaker applies to the three-phase AC 50Hz, 10kV power system for switching the load of various nature and frequent operation of occasions, available for the protection of industrial and mining enterprises, power plants and substations electrical equipment and control purposes. Handcart Center can be equipped with KYN28A-12 (GZS1) switchgear can be equipped in XGN-fixed switch cabinet. This product meets the national standard GB1984 "AC high voltage circuit breaker, JB3855 3.6-40.5kV Indoor AC high voltage vacuum circuit breaker" and IEC60056 "high-voltage AC circuit breaker" standard. Meet the high voltage circuit breaker DL/T403 12-40.5kV households-order technical conditions ". Environmental conditions, environmental temperature: up to +40 ° C, the lower limit of -10 ° C; 3, relative humidity: daily average relative humidity: ≤ 95%; monthly mean relative humidity: ≤ 90%; daily average saturation vapor pressure: ≤ 2.2 × 10-3MPa, monthly average saturated vapor pressure: ≤ 1.8 × 10-3MPa Altitude: 2000m and below; 4, seismic intensity: no more than 8 degrees; the 5 spaces non-flammable, explosion hazards, chemical corrosion and severe vibration. The structural characteristics of a circuit breaker interrupter actuator part before and after configuration, connected through a transmission mechanism as a whole to ensure overall with the performance of the circuit breaker. 2 in sealed ceramic vacuum interrupter, CuCr contact materials and contact structure of the longitudinal magnetic field of the world today recognized as the most advanced way of arc extinction. 3, the vacuum interrupter chamber is installed in the APG new art molded insulating cylinder, not only reduces the overall size of the circuit breaker, but also to prevent a foreign object damage and surface contamination of the arc quenching. Insulation cylinder draw on the advantages of similar foreign products on the basis of, additional skirts and ribs to improve the insulation level and the ability of anti-dynamic stability current. 5 operating mechanism with spring energy, has both electric and manual energy, energy storage spring breaker work through the output cam is passed to the linkage mechanism, and then passed through a link mechanism to the moveable contact and no section. Advanced reasonable buffer device sub-gate with no rebound weaken opening shock and vibration. 7, without adjustment, minimal maintenance or maintenance-free. 8, the institutional life of up to 20,000 times.
