6kv, 10kv, 12kv Kyn/Xgn Fix Type Medium Voltage Switchgear
General
KYN/XGN High Voltage Switchgear 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: -15
2. Altitude: no more than 4000m
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 2.2×10³MPa, 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".
Switchgear Structure
Structural features
1. Xgn15-12 type combined sulfur hexafluoride ac metal closed-loop switchgear is a new generation of metal closed switchgear with sulfur hexafluoride switch as the main switch, air insulation, compact structure, expandable.It is characterized by simple structure, flexible operation, reliable interlock and convenient installation.It has different applications.According to the requirements of different users to provide satisfactory technical solutions.
2. The adoption of sensor technology and protective relays, coupled with advanced technical performance and portable and flexible assembly solutions, can meet the changing needs of the market.
3. Xgn15-12 unit sulfur hexafluoride ring cabinet is suitable for 50hz, 12kv ac power system, widely used in industrial and civil cable ring network and power supply terminal engineering.Especially suitable for the following places: special places requiring automatic switching of double power supply, urban residential distribution network, small secondary substation, open and close houses, industrial and mining enterprises, shopping malls, airports, subway, wind power, hospitals, stadiums, railways, tunnels, etc.
4. Protection level up to IP2X.
