Structural Composition

The complete set of three-phase oil-immersed transformer mainly consists of the following core parts:

1. Iron CoreLaminated silicon steel sheets are stacked to form the magnetic circuit of the transformer, featuring low magnetic loss and stable magnetic conductivity.

2. WindingsComposed of high-voltage primary winding and low-voltage secondary winding, the whole winding assembly is fully immersed in insulating oil for insulation and heat dissipation.

3. Oil TankSealed welded steel structure, which stores insulating oil and holds the iron core and windings integrally.

4. Oil ConservatorMounted on the top of the tank to compensate the volume expansion and contraction of insulating oil caused by temperature fluctuation.

5. RadiatorHeat exchange component for fast heat dissipation of transformer oil to control internal operating temperature.

6. Insulating BushingsInsulate high and low voltage outgoing leads and realize reliable connection with external power circuits.

7. On-load / Off-circuit Tap ChangerInstalled inside the oil tank to adjust output voltage according to actual grid load conditions.

8. Auxiliary AccessoriesEquipped with breather, explosion-proof pipe, gas relay, temperature indicator and other protective monitoring components.

Operating Principle

The three-phase oil-immersed transformer works on the electromagnetic induction law.After alternating current is input to the primary winding, alternating magnetic flux will be generated and transmitted through the iron core. The alternating magnetic field induces electromotive force on the secondary winding, realizing voltage transformation and power transmission between different voltage levels.

Product Advantages

1. Excellent heat dissipation performanceInsulating oil serves as cooling medium with high heat transfer efficiency, effectively lowering the operating temperature of windings and iron core.

2. Low running noiseTransformer oil plays a sound buffer role to greatly reduce mechanical and electromagnetic noise during operation.

3. Cost-effective & long service lifeReasonable structural design cuts manufacturing cost, with stable components to extend service cycle.

4. Outstanding environmental adaptabilityAvailable for both indoor and outdoor installation, with strong resistance to temperature and humidity changes.

Application Fields

1. Power Grid Distribution SystemUsed as distribution transformers to step down high voltage into standard low voltage for terminal power consumers.

2. Industrial & Mining ProjectsStable power supply for factory workshops, mining areas, commercial complexes and residential buildings.

3. Scientific Research & Test InstitutionsSupport matching high-voltage test equipment for laboratory power conversion experiments.
