AC switchgear XGN2-12

three-phasefixed

Product introduction XGN2-12 box-type fixed metal-enclosed switchgear (hereinafter referred to as the switchgear) is used for power acceptance and distribution of 50Hz three-phase AC system of 12KV or below. It is especially suitable for occasions of frequent operation. Single busbar system is adopted. (Single busbar with bypass and double-busbar structure might be derived). XGN2-12(G) box-type fixed AC metal-enclosed switchgear is a plateau type product derived from common switch and is suitable for using in high altitude areas. The switchgear meets requirements of state standard GB3906 A.C. Metal-Enclosed Switchgear for Rated Voltages of 3-35kV and International Standard IEC298, and is equipped with sound "Five-prevention” lock function. Main switch of the switchgear is equipped with ZN28A-10 vacuum circuit breaker and SN10-10 oil-minimum breaker, CD10 and CD17 electromagnetism as well as CT8 and CT17/CT19 spring operating mechanism. According to user demands, ZN28-10, ZN73 and other integrated circuit breaker might be used. CN30-10 rotary disconnecting switch, GN22-10 heavy current disconnecting switch and GN30-10 rotary heavy current disconnecting switch are adopted. Normal using environment: 1. - Ambient temperature: upper limit +40°C; lower limit-25°C. 2. - Altitude: no more than 1,000m, altitude for plateau type switchgear should not exceed 3,000m. 3. - Relative humidity: daily mean <95%, monthly mean<90%; 4. - Water vapor pressure: annual mean: < 2.2x10Mpa, monthly mean < 1.8x10Mpa. 5. - Seismic intensity: no more than magnitude 8°. 6. - Places without fire disaster, explosion risk, heavy pollution, chemical corrosion and violent vibration.
