Advantages of European-style Prefabricated Substations
European-style prefabricated substations, represented by models like ZBW and YB series, offer several
key advantages in power distribution systems:
1. **Modular Three-Compartment Design**
- They feature a **three-compartment integrated structure** (high-voltage compartment, transformer
compartment, and low-voltage compartment), ensuring clear functional separation and easy maintenance.
- The modular layout allows for flexible configuration and scalability, adapting to various power capacities
(e.g., 315kVA to 1000kVA).
2. **High Reliability and Safety**
- Equipped with **high-quality components** such as XGN15/HXGN17 switchgear and S11/S13 oil-immersed
or SCB10 dry-type transformers, they ensure stable performance and long service life.
- Ring main unit (RMU) configurations support both **ring and radial power supply**, enhancing grid redundancy
and reducing downtime risks.
3. **Efficient Maintenance**
- The separate compartments enable **targeted maintenance** without disrupting the entire system. For example,
the transformer can be replaced independently.
- Their design allows for easy access to components, minimizing repair time and labor costs.
4. **Environmental Adaptability**
- Robust enclosures with corrosion-resistant coatings and sealed structures protect against moisture, dust,
and extreme temperatures, making them suitable for harsh environments.
- Optimal ventilation systems (e.g., natural vents or fans) ensure stable operating temperatures, extending
equipment lifespan.
5. **Flexible Applications**
- Widely used in urban power grids, industrial parks, and residential areas, they efficiently handle medium-voltage
(10kV) to low-voltage (0.4kV) power conversion.
- Customizable features (e.g., smart monitoring,无功补偿) meet evolving grid requirements.
These advantages make European-style substations a preferred choice for reliable, cost-effective, and space-efficient
power distribution solutions.
