The YB□-12 American-style prefabricated substation is designed for 10kV ring main, dual power supply, or terminal power supply systems. It integrates transformation, metering, compensation, control, and protection functions into a single unit.
Compliance Standards:
GB/T17467-1998 "High-voltage/Low-voltage Prefabricated Substations"
DL/T537-93 "Technical Requirements for Ordering 6-35kV Prefabricated Substations"
Operating Conditions
Altitude: ≤1000 meters
Ambient temperature: -35℃ to +40℃
Relative humidity: Daily average ≤95%, monthly average ≤90%
Installation site: Free from fire and explosion hazards, chemical corrosive gases, with good ventilation; ground slope ≤3°
Core Advantages and Features
1. Fully Insulated and Sealed Structure
Enables maintenance-free or low-maintenance operation, significantly enhancing personnel and equipment safety.
2. Compact Design
Occupies only 1/3 to 1/5 of the space of European-style substations with the same capacity, allowing flexible installation and reduced land usage.
3. Optional Split-Type Structure
Prevents transformer oil contamination for cleaner and easier maintenance.
4. High-Voltage Dual-Fuse Full-Range Protection
Provides reliable overload and short-circuit protection while reducing costs.
5. Highly Flexible Connection Modes
Suitable for both ring main and terminal power supply systems; cable connectors support emergency plugging/unplugging under 200A load current.
6. Efficient Thermal Insulation and Heat Dissipation Enclosure
Honeycomb double-layer composite panel structure balances heat retention and ventilation.
7. Low-Voltage Electronic Phase-Loss Protection
Continuously monitors voltage abnormalities and quickly trips the main switch to protect electrical equipment.
8. Ready for Smart Upgrades
High-voltage side offers oil-immersed or SF6 load switches with optional motorized operation, facilitating future distribution automation upgrades.
