Factors that may affect the accuracy of transformer fault diagnosis
Accuracy of testing equipment: If the testing instruments used, such as thermometers, voltmeters, ammeters, insulation resistance testers, etc., have insufficient accuracy or inaccurate calibration, it can lead to measurement data errors, thereby affecting the judgment of faults.

Internal structure construction of transformer
Core: The magnetic circuit part of a transformer, usually composed of hot-rolled or cold-rolled silicon steel sheets with high silicon content, thickness of 0.35-0.5mm, and surface coated with insulating paint stacked together. The iron core is divided into two parts: the iron core column and the transverse plate. The iron core column is equipped with windings, and the transverse plate is used to close the magnetic circuit. There are two basic forms of iron core structure: core type and shell type. The core column of the transformer with core type structure is surrounded by the winding, which has a simple structure, easy assembly and insulation, and is therefore widely used; The shell structure transformer core surrounds the winding and has high mechanical strength, but the manufacturing process is complex and requires a lot of materials. It is usually only used for low-voltage high current transformers or small capacity power transformers.

Maintenance steps for box type transformer
Preparation before maintenance Personnel preparation: Maintenance personnel should have professional electrical knowledge and rich experience in transformer maintenance, familiar with the structure and working principle of box type transformers. Tool preparation: Prepare testing instruments (such as multimeters, insulation resistance testers, etc.), maintenance tools (such as wrenches, screwdrivers, etc.), and safety protective equipment (such as insulated gloves, insulated shoes, safety helmets, etc.). Material preparation: Prepare relevant technical materials for the box type transformer, including product manuals, electrical schematics, wiring diagrams, etc.

Detailed introduction of dry-type transformer
Working Principle: Dry type transformers use the principle of electromagnetic induction to transmit electrical energy or signals from one circuit to another. When AC current passes through the primary coil (i.e. the primary winding), alternating magnetic flux is generated in the iron core. Since the primary and secondary windings are on the same iron core, when the magnetic flux passes through the secondary winding (i.e. the secondary winding), induced electromotive force is generated on the secondary side of the transformer, thereby achieving voltage conversion. The output voltage is determined by the ratio of the turns of the primary coil and the secondary coil.

Detailed introduction of oil immersed transformer
Working Principle: Oil immersed transformers, like other transformers, operate using the principle of electromagnetic induction. When an alternating voltage passes through the primary winding, an alternating electromotive force is generated inside the winding, which excites eddy current motion inside the iron core, and then induces electromotive force in the secondary winding to achieve voltage transformation.

Internal structure of distribution cabinet
Cabinet: Framework: It is the supporting structure of the distribution cabinet, usually made of metal materials such as steel, with sufficient strength and rigidity to withstand the weight of internal electrical components and possible external forces, ensuring the stability of the cabinet. Shell: It plays a role in protecting internal electrical components, preventing dust, moisture, foreign objects, etc. from entering the cabinet, and avoiding damage to electrical components. The material of the shell is generally metal and requires good protective performance. Some distribution cabinets used in special environments may also need to have explosion-proof, anti-corrosion and other characteristics.
