Transformer skeleton is one of the core components of transformer, which undertakes the functions of supporting core and insulating parts, conducting magnetic flux, etc. It plays a decisive role in the performance and life of transformer. This article will introduce the use of transformer bobbins and their maintenance methods, to help readers better understand and apply transformer bobbins

A, the use of transformer frame

         Transformer skeleton is one of the core components of the transformer, it is usually made of high performance cold-rolled silicon steel plate, to undertake the following main functions:

         Support the core: Transformer core is composed of multiple chips with precise shape and size, and the core needs to be supported by the skeleton around it. By fixing the chips, the transformer skeleton ensures that the core is in a regular shape, thus ensuring the performance and stability of the transformer.

         Conducting flux: The material of transformer skeleton should have good magnetic conductivity to facilitate efficient flux conduction when the current passes through the core and improve the efficiency of the transformer.

         Support insulating parts: Transformer insulating parts are used to ensure the safety and reliability of the transformer, and the skeleton supports the installation position of the insulating parts to make it firm and stable, effectively avoiding the wear and damage among the insulating parts.

         Reduce magnetic loss and noise: good transformer skeleton can reduce the magnetic loss and noise of the transformer, improve the efficiency and service life of the transformer.

         Second, the transformer skeleton maintenance methods

         Regular cleaning: transformer skeleton in use will be eroded by dust and dirt, these substances will affect the magnetic conductivity of the skeleton, insulation and heat dissipation, thus affecting the performance and life of the transformer. Therefore, it is necessary to clean the transformer skeleton regularly to keep it clean and tidy.

         Surface anticorrosion: transformer skeleton needs to be surface anticorrosion treatment to prevent rust and oxidation of the core, reduce parts aging and resistance to loss of capacity. In the surface anti-corrosion treatment, should choose the appropriate coating materials, in strict accordance with the requirements of the coating thickness and treatment process.

         Insulation treatment: In order to prevent corona phenomenon on the surface of transformer skeleton, insulation treatment is required on the core surface to prevent corona generation and improve insulation performance. Insulation material usually uses a special coating, such as aluminum oxide or zinc phosphate, etc.

         Check the fixation of the core: transformer skeleton should be regularly tested for the fixation of the core and the stability of the structure, once the skeleton is found to be deformed or the chip becomes loose, repairs should be carried out immediately to avoid causing accidents.

         Check the insulating parts: Insulating parts are another important part of the transformer, its condition has a great impact on the service life and safety of the transformer, so it is necessary to regularly check the wear and tear of the insulating parts, damage and other conditions, once the problem is found should be replaced and repaired in a timely manner.

         In short, the correct care and maintenance can effectively extend the service life of the transformer skeleton and improve its performance, so we should do a good job of transformer skeleton maintenance work, regular cleaning, painting, inspection and maintenance of it. At the same time, the installation and commissioning of the transformer also need to be for the characteristics of the skeleton, strict control of the tightness, so that the core is fixed firmly and does not produce vibration and other problems, in order to ensure the safety and reliability of the transformer.
