The three-phase distribution transformer is the core equipment in the power system, which realizes the conversion of three-phase AC voltage and power distribution through the principle of electromagnetic induction. Its core functions include
01
Voltage Conversion:
Steps down high-voltage grid power (e.g., 10kV) to a lower voltage suitable for the user (e.g., 400V/230V).
02
Energy Transmission:
Boosts voltage at power plants to reduce transmission losses over long distances, then steps it down through multiple substations to the distribution network.
03
System Compatibility:
Supports three-phase, four-wire power supply, catering to both power equipment (380V) and lighting loads (220V).
Standard Groups:
| Group Symbol | Application Scenario |
|---|---|
| Yyn0 | Power and lighting mixed load power supply |
| Yd11 | Low-voltage industrial line |
| YNd11 | Grounded high-voltage system above 110kV |
Key technical parameters
Rated Capacity: 10kV distribution transformers typically range from 315kVA to 2500kVA. Pole-mounted transformers are limited to 315kVA and below.
Operating Environment: Suitable for temperatures between -25°C and 40°C, altitudes ≤ 1000m, and humidity ≤ 90% at 25°C.
Energy Efficiency: S11 series oil-fired transformers and SCB10 series dry-type transformers are common energy-saving models.

Application Scenario
Power Transmission Chain: Power generation at power plants → High-voltage transmission → Multi-stage step-down at substations → Distribution to end users
End-user power supply: Core equipment for industrial and mining enterprises, construction sites, data centers, and urban distribution networks
Specific application scenarios: Dry-type transformers are used in locations with high fire safety requirements (such as airports and hospitals)
