Transformers consist of several essential parts that work together to facilitate the conversion of electrical energy from one voltage level to another. The main parts of a transformer include the core, windings, insulation and tank. The core, usually made of laminated steel or iron, provides a path for the magnetic flux generated by the windings. The windings, consisting of primary and secondary coils, are wound around the core and carry the electrical currents which induce the voltage in the secondary winding. Insulating materials such as paper, varnish and oil are used to insulate the windings and prevent electrical degradation. The reservoir surrounds the core and windings and is filled with insulating oil to dissipate heat and provide mechanical support.
A 12 volt transformer refers to a transformer with a voltage rating of 12 volts (V). Transformers are typically rated based on their voltage and power handling capacity, with voltage indicating the maximum voltage the transformer can safely handle. A 12 transformer is designed to step up or exceed voltage levels to produce a 12 volt output, suitable for various applications such as powering electronic devices, charging batteries or powering lighting systems.
The names of transformer parts vary depending on their function and location in the transformer. Some of the key parts of a transformer include the core, windings, insulation, tank, bushings, tap changer, cooling system and accessories. The core provides a magnetic path for the flux generated by the windings, while the windings carry the electrical currents that induce the voltage in the secondary winding. Insulation materials prevent electrical degradation between the windings and the core. The tank houses the core and windings and contains insulating oil to dissipate heat. Bushings provide connections for incoming and outgoing electrical conductors, while tap changers allow adjustments to the transformer output voltage. Cooling systems, such as fans or radiators, remove excess heat generated during operation. Accessories may include monitoring devices, protective relays and control panels to ensure safe and reliable operation of the transformer.
