Single-phase transformer

Product Definition

A single-phase transformer is a stationary electrical device based on the principle of electromagnetic induction, used exclusively in single-phase alternating current circuits. Its main function is to step up, step down, or isolate voltage. As a key equipment for power conversion in single-phase power systems, it is widely applied in low-voltage distribution, household power supplies, small industrial equipment, and other scenarios.

Core Structure

1. Iron core: Made of high-quality cold-rolled silicon steel sheets using laminated processing technology, which reduces hysteresis and eddy current losses and improves electromagnetic conversion efficiency.

2. Windings: Consist of high-voltage and low-voltage windings wound with high-strength insulated wires. Features high insulation grade and excellent conductivity.

3. Tank/enclosure: Depending on insulation and cooling mode, it is divided into oil-immersed tanks (for oil-covered transformers) and dry-type protective enclosures (for dry-type transformers), providing dust-proof, moisture-proof, and mechanical impact protection functions.

4. Insulation system: Uses heat-resistant and aging-resistant insulation materials to ensure equipment efficiency and service life under designed operating conditions.

5. Accessories: Including wiring terminals, temperature measurement instruments, protective devices, and other components to ensure safe and stable operation of the equipment.

7. Key advantages

8. Simple and compact design, small size, light weight, easy installation and transportation, with low overall cost;

9. Suitable for single-phase power networks, with good compatibility in residential, small commercial, and other single-phase electricity consumption scenarios;
