Execution standards for oil immersed transformers

1、 Overview

Oil immersed transformers are one of the common power equipment in the power system, and their standards mainly include national standards and industry standards. When purchasing, installing, and using oil immersed transformers, it is necessary to follow the relevant standards to ensure the quality and safety of the equipment.

2、 National standards

The National Electrotechnical Standardization Technical Committee (SAC/TC213) has developed the following standards for oil immersed transformers:

1. GB 1094.1~2-2013 "Power Transformers"

2. GB 1094.3~5-2003 "Temperature Monitoring Devices for Power Transformers"

3. GB 1094.6-2002 "Test Methods for Insulation of Power Transformers"

These national standards specify the requirements for the design, manufacturing, testing, transportation, installation, and use of oil immersed transformers, ensuring their safe, reliable, and efficient operation.

3、 Industry standards

In the application field of oil immersed transformers, there are also some industry standards, such as the following:

1. DL/T 596-1996 "Operation and Maintenance Regulations for Oil immersed Transformers"

2. DL/T 846-2001 "Guidelines for Maintenance and Overhaul of Oil immersed Transformers"

3. DL/T 951-2005 "Test Method for Short Circuit and High Temperature Overheating of Oil Immersed Transformer Winding"

4. DL/T 1088-2016 "Operation Evaluation of Power Transformers"

These industry standards focus on the use and maintenance of oil immersed transformers, including operation, maintenance, fault handling, and evaluation analysis, which are of great significance for ensuring the normal operation of oil immersed transformers and extending equipment life.

4、 Conclusion

The standards for oil immersed transformers include two categories: national standards and industry standards. National standards are the basic standards that guide the design, manufacturing, and installation of oil immersed transformers, while industry standards focus more on the requirements for the operation, maintenance, and evaluation of oil immersed transformers. When selecting and using oil immersed transformers, it is necessary to carefully understand and comply with the relevant standards to ensure equipment quality and safe use.
