Description
10kv 11kv Air Insulated Switchgear
KYN28-12 switchgear is a complete set of power distribution device for 3~12kV three-phase AC 50HZ single busbar and single busbar sectional system.
Mainly used in power plants, small and medium-sized generators, power distribution in industrial and mining enterprises, and secondary substations in electrical systems for power reception, power transmission, and starting of large high-voltage motors.
Service Conditions
◎ Ambient airtemperature: -15°C~+40°C;
◎ Relative humidity: Daily average 95%，and daily average of water vapor pressure < 2.2kPa;
◎ Monthly average «90%, and monthly verage of water vapor pressure < 1.8kPa;
© Altitude: ^1000m;
◎ Seismic intensity: not beyond Ms8.
◎ Ambient air should be free of pollution of corrosive or flammable gas or vapor;
◎ No obvious vibration;
Structural features:
It adopts all-metal module assembly type, anti-corrosion imported aluminum-zinc coated cabinet, processed by CNC high-precision equipment, and adopts advanced multi-folding technology. High strength nut, light weight and good strength.
The switchgear can be equipped with VD4 series, ZN65 series and other vacuum circuit breakers produced by our company, with wide adaptability and strong interchangeability.
The product has good general characteristics and can be equipped with various and multi-brand handcart-type vacuum circuit breakers. It is more widely used and has a very high product performance-price ratio.
1: STRICT protection step to ensure personal safety
2: The cable room can be installed as many as 9 single-core cables
3: Operation and testing positions will be established for the handcart, and both positions are equipped with safe and reliable positioning device and display device
4: The enclosure is completely assembled from aluminized and galvanized steel plate, which are machined and bent by machine tool and then bolted.
5: It has high mechanical strength and its neatness and beauty is ensured.
6: The switchboard door is sprayed with plastic, also has strong capacity of impact resistance and corrosion protection.
7: The primary switch may be provided with VD4 vacuum circuit breaker and C3 series of fixed type load switch from ABB, various domestic vacuum circuit breakers (such as VS1, VH1, VK, ZN28) may also be provided in lieu of the same foreign products.
8: Front door is installed with a observation window to check the operating state of the components inside the room
