1. mechanical strength and protection level : KYN28A-12 switchgear cabinet is made of aluminum-zinc coated steel plate after multi-bending and forming by CNC machine tool and assembled by bolts, which has high mechanical strength to ensure neat and beautiful products. The cabinet door is sprayed with plastic coating, which has strong impact resistance and corrosion resistance.
2. circuit breaker configuration : the main switch of the equipment can be configured with VS1 vacuum circuit breaker, but also can be configured with a variety of domestic series of vacuum circuit breakers (such as VD4, VH1, VK, VJD) to replace similar foreign products. No matter what type of circuit breaker is selected, the bare conductor air insulation distance can be ensured to be greater than 125mm, and the composite insulation is greater than 60mm. These circuit breakers have the unique advantages of long life, high parameters, less maintenance and small size .
3. intelligent function : KYN28A-12 switchgear can be configured with intelligent measurement and control protection device, support 6 or 9 points online temperature measurement technology, can realize remote control electric operation ground switch, electric shaking in and out circuit breaker hand car and cabinet internal fault arc protection functions, further improve the intelligent level of equipment .
4. Scope of application and installation conditions : the equipment is suitable for three-phase AC 50Hz, 12kV power system, mainly used in power plants, substations and industrial and mining enterprises, railway transportation, high-rise building transformer and distribution system. The operating conditions include ambient air temperature with a maximum of +40ºC and a minimum of -15ºC, humidity with a daily average relative humidity ≤95% and a monthly average relative humidity ≤90%, altitude of 3000 meters or less, seismic intensity not exceeding 8 degrees, ambient air should not be exposed to corrosive or combustible gas, water vapor and other obvious pollution, and there is no frequent violent vibration .
5. standard and certification : KYN28A-12 armored detachable AC metal enclosed switchgear conforms to IEC298, IEC694, GB3906 and DL404 and other standards and requirements, with perfect and reliable anti-error operation function .
