Transformer Compenents
The basic structure of a large power transformer is generally divided into the following seven components:
• Core assembly—consisting of the limbs and yokes (stacked from silicon steel sheets) and their clamping mechanisms
• Winding assembly—comprising the windings for each phase and the leads used for their connections
• Insulation system—including the oil and paper insulation between various components, as well as the insulation within the components themselves
• Tank assembly—encompassing the main tank, the oil conservator, support structures, etc.
• Cooling system—consisting of coolers or radiators, oil pumps, fans, connecting piping, etc.
• Measuring instruments—including thermometers (with signal contacts), current transformers, oil level gauges, etc.
• Protective devices—such as pressure relief devices, gas relays (Buchholz relays), breathers (moisture absorbers), etc.
Among these, the first two components—the core and the windings—are also referred to as the magnetic circuit and the electric circuit, respectively, and constitute the fundamental parts of the transformer.
