A transformer is a device that changes an alternating voltage using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil, and an iron core (magnetic core). The main functions are as follows: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), and the like. According to the application, the method can be divided into: power transformers and special transformers (furnace transformers, rectification transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers, reactors, mutual inductors, etc.). The circuit symbol is usually T as the beginning of the number, for example: t01, T201, etc.

When the transformer winding is wound, an insulating and high-temperature-resistant sleeve penetrates through a copper wire at the pin positions of the wire starting and winding, so that the outgoing wires and the transformer shell are better insulated, the safety and reliability of products are improved, and the outgoing wires are fixed. The insulating sleeve has the forms of a pure porcelain sleeve, an oil-filled sleeve, a capacitor sleeve and the like due to different voltage grades. The pure porcelain bushing is mainly used for transformers of 10kV and below, a conductive copper rod is penetrated in the porcelain bushing, and air insulation is adopted in the porcelain bushing; the oil-filled bushing is mainly used for 35kV transformers, oil is filled in a porcelain bushing, a conductive copper rod penetrates through the porcelain bushing, and insulating paper is wrapped outside the copper rod; the capacitive bushing is used for a high-voltage transformer with the voltage of more than 100kV and comprises a main insulating capacitor core, an upper and a lower external insulating porcelain pieces, a connecting guide pin, an oil conservator, a spring assembly, a base, a voltage-sharing ball, a measuring terminal, a wiring terminal, a rubber gasket, insulating oil and the like.
