What is the Structure and Functions of transformer?

The fundamental structure of a transformer comprises a core, winding, and insulation components. In order to ensure the safe and reliable operation of the transformer, it is also equipped with components such as an oil tank, voltage-regulating device, cooling system, and protective devices. The following is a detailed explanation of the structure and functions of each part of the transformer:

1. Body

(1) Core: Functions as the magnetic circuit.

(2) Winding: Serves the purpose of an electrical circuit.

(3) Insulation components

(4) Lead wire

2. Voltage-Regulating Device

Used to change the number of winding turns and adjust the voltage.

3. Oil Tank and Cooling System

(1) Oil Tank: Used for storing oil and supporting the body.

(2) Cooling System: Achieves the cooling of the transformer by circulating oil, serving the purpose of temperature reduction.

4. Protective Devices

(1) Oil Conservator: Reduces the contact surface between oil and air, regulates oil quantity, and facilitates oil filling.

(2) Safety airway: Prevents excessive internal pressure in the event of internal faults.

(3) Moisture Absorber: Absorbs impurities and moisture from the air, filtering the air.

(4) Gas Relay: Acts as a protective device in case of gas generation due to winding short circuit, insulation breakdown, core faults, oil leakage reducing oil levels, etc.

(5) Temperature Gauge: Monitors the operating temperature of the transformer.

5. Outlet Bushing

Used to lead the ends of the winding out of the oil tank, requiring a sufficient insulation distance from the ground.

6. Transformer Oil

Functions as both insulation and cooling medium.
