Exploring Dry Type Transformer Winding: Definition, Features, Applications, and Maintenance

With the continuous development of power equipment technology, the application of Dry Type Transformer Winding (DPTW) in the power system is becoming increasingly widespread. Dry Type Transformer Winding is a type of transformer winding that operates in a completely dry environment.

Features of Dry Type Transformer Winding

  1. Safety and environmental protection: DPTW does not use oil or other flammable media, so it is highly safe and will not cause pollution to the environment.
  2. Easy maintenance: Due to the lack of oil, the maintenance cost of DPTW is relatively low, and regular maintenance is relatively simple.
  3. High reliability: Due to the absence of leakage and aging issues in the windings of oil-immersed transformers, the reliability of DPTW is higher.
  4. Energy saving and efficiency: DPTW has a higher energy efficiency level, which can help users save energy and reduce operating costs.

The application areas of Dry Type Transformer Winding

  1. Power system: DPTW is widely used in power systems for boosting, reducing, and transforming processes, providing reliable support for power transmission and distribution.
  2. Industrial automation: In industrial automation, DPTW is often used for the power supply of control systems, providing stable and reliable power for various equipment.
  3. Data center: With the popularization of cloud computing and big data technology, data centers have increasingly high requirements for power supply stability. As an important piece of equipment in data centers, DPTW can ensure the continuity and stability of the power supply.
  4. New energy field: DPTW is also widely used in new energy, such as solar inverters, power supply for wind power generation systems, etc.

How to improve the efficiency and reliability of Dry Type Transformer Winding

  1. Optimize design: Improving the winding structure and materials reduces resistance and magnetic losses and improves energy conversion efficiency. At the same time, a reasonable design of the heat dissipation system ensures that the temperature distribution of the transformer winding is uniform during operation, preventing performance degradation caused by overheating.
  2. Adopting advanced manufacturing technology: using advanced insulation materials and manufacturing processes to improve windings’ mechanical strength and electrical performance and reduce the failure rate during operation. At the same time, strengthen quality inspection and process control to ensure that every step meets quality standards.
  3. Strengthen maintenance and upkeep: Conduct regular inspections and preventive maintenance to promptly discern and address potential issues. Keep the winding clean and dry, avoiding factors such as moisture and dust that may affect its performance. Regularly conduct electrical and mechanical performance tests to ensure the windings are operating well.
  4. Reasonable load configuration: Reasonably configure the load according to actual needs to avoid long-term overload or light load operation. Overloading can cause the winding to overheat and accelerate insulation aging; A light load can lead to low efficiency. By properly configuring the load, the winding can operate at its optimal state, improving overall efficiency and reliability.

Issues to note when using and maintaining Dry Type Transformer Winding

  1. Safety issues: Safety regulations should be followed during use to ensure the safety of operators. Avoid using DPTW in flammable and explosive environments and ensure good grounding and safety.
  2. Environmental adaptability: DPTW should be installed in a dry, well-ventilated, and noncorrosive gas environment. Avoid placing it under high temperatures, humidity, or extreme weather conditions to avoid affecting its normal operation and service life.
  3. Regular inspection and maintenance: Regular inspections and maintenance work should be carried out to check whether the winding’s temperature, sound, odor and other parameters are normal. Clean the dust and dirt on the surface of the winding to maintain its neat appearance. Regularly check if fasteners are loose and promptly handle them. At the same time, regular maintenance work should be carried out according to the producer’s recommendations.
  4. Operating standards: Operators should receive professional training and be familiar with the operating criteria and safety regulations of DPTW. During the operation process, relevant regulations should be strictly followed to avoid equipment damage or accidents caused by misoperation.
