Distribution Transformer

11KV

33KV

1. Voltage Transformation: Achieves high-low voltage conversion through electromagnetic induction principle.

2. Power Distribution: Directly supplies power to end-users, covering industrial, commercial, and residential electricity needs.

3. Energy Efficiency Management: Modern distribution transformers focus on low-loss and low-noise design, complying with national energy efficiency standards.
   II. Structure and Working Principle

4. Main Structure

• Core: Consists of laminated silicon steel sheets forming the magnetic circuit.

• Windings: Made of copper wire, forming the electrical circuit. Together with the core, they complete electromagnetic energy conversion.

• Oil Conservator: Regulates oil volume changes, reduces oil-air contact, and extends service life.

• Insulation Bushings: Insulated support components for high and low voltage leads, mostly made of porcelain materials.

• Protection Devices: Includes gas relays (gas protection) and explosion-proof pipes for fault detection and safety protection.
