XGN2-12 Indoor Metal-enclosed High Voltage Power Distribution Panel
Product name
XGN2-12 Indoor Metal-enclosed High Voltage Power Distribution Panel
Model
XGN2-12
General
XGN2-12 Indoor Metal-enclosed High Voltage Power Distribution Panel is mainly used as reception and distribution of power supply of 3.6, 7.2 and 12KV, 3Phase AC, 50Hz in indoor system.
It is specially applied to cases where frequent operations are needed. The main switch applies ZN28A-12 segmental type vacuum breaker with CD10 electromagnetic operational mechanics, CT8/CT19A (B) spring operational mechanics, ZN28-12 series integral vacuum breaker (with CD17 Electromagnetic Operational mechanics, CT17/CT19 spring operational mechanics) or applies ZN63-12(VS1) vacuum circuit breaker. Isolation switch applies GN30-10 rotating style and GN22-10 high current isolation switch.
Ambient conditions
1. Ambient temperature: Upper limit +40; Lower limit: -25
2. Altitude: No more than 1000m
3. Relative humidity: Daily average humidity no more than 95%, and monthly average no more than 90%
4. Steam pressure: Daily average pressure no greater than 2.2× 10³ MPa, monthly average no greater than 90%
5. Seismic intensity: No greater than 8 degree
6. No fire, explosive danger, grave filth, chemical corrosion and drastic vibration on the site.
Advantages
1. This switchgear is case metal-enclosed structure. In accordance with the national standard GB3906 and international standardIEC298, protection degreeIP2X. The metal-enclosed structure effectively prevents short-circuit failure by intruders.
2. When air insulation distance between polar to polar or polar to ground ≤ 125mm, porcelain support insulators (≥ 8000N) is applied. All these ensure higher insulation intensity and stability.
3. Breakers, both upper and lower insulation switches, grounding switches and interlock mechanisms between doors all takes force mechanical lock mode to meet the requirement of "five- prevention".
