Main Components of a Transformer
Part One
The basic structure of a power transformer is generally divided into the following seven parts:
Core: Includes columns, yokes, clamping devices, etc., all made of silicon steel sheets.
Winding Section: Consists of the supply windings of each phase and their connections.
Insulation Section: Includes oil insulation, paper insulation, and other insulation between components and between different parts.
Tank Section: In addition to the main tank body, it also includes oil conservators, brackets, and related fittings.
Cooling System: Includes coolers or radiators, oil pumps, fans, connecting pipes, etc.
Measuring Instruments: Includes signal thermometers, current transformers, oil level indicators, etc.
Protective Devices: Such as safety valves, gas relays, moisture absorbers, etc.
Among these, the first two parts are also referred to as the magnetic circuit and the electric circuit, which form the core structure of the transformer.
