How to improve the service life of box-type transformers?

Box-type transformers, also known as box-type substations, are important equipment in the power system. The length of their service life is directly related to the stability and safety of the power system. To improve the service life of box-type transformers, we need to start from multiple aspects. Today we will discuss how to improve the service life of box-type transformers.

1. Reasonable selection of installation location

Box-type transformers should be installed in a well-ventilated and dry environment, which can avoid humid and high temperature environments, and prevent the presence of corrosive gases or chemicals around them. These can effectively reduce the aging speed of the equipment.

2. Choose high-quality materials

The frame structure of the box-type transformer is composed of iron core, coil and insulation material. The iron core and coil are the core components of the box-type transformer. In order to extend the service life of the box-type transformer, we can start with material selection. The selection of high-quality iron core materials can improve the energy efficiency of the transformer, and can effectively reduce magnetic loss and temperature rise, thereby extending the service life of the transformer.

3. Regular inspection and maintenance

Box-type transformers should not only be inspected and maintained after installation, but also need to be frequently inspected and maintained to ensure the long-term stable operation of the box-type transformer. During use, the box-type transformer needs to be inspected regularly, including confirming the normal working state of the core, coil and insulation material, checking whether the box-type transformer is operating normally under load, and observing whether the box-type transformer can operate normally during operation. If you encounter a part that needs to be replaced, you need to replace it in time.

4. Control the load

Overload operation is one of the main reasons for shortening the service life of box-type transformers. Overload will cause the internal temperature of the transformer to rise, accelerate the aging of the insulation material, and even cause failures. Therefore, we must operate the transformer according to the rated load and avoid overload. Specifically, we should regularly monitor the load of the transformer and promptly detect and adjust the load changes to ensure that it always operates within a safe range. During the production process, we must reasonably arrange the production plan according to the load capacity of the transformer to avoid long-term overload operation.

5. Pay attention to heat dissipation

Poor heat dissipation is one of the important reasons for the failure of box-type transformers. Therefore, the heat dissipation problem of the transformer should be taken seriously. We must take effective measures to improve its heat dissipation effect. For example:

Clean the radiator regularly: The radiator is one of the main components for heat dissipation of the transformer. Dust and debris on the radiator should be cleaned regularly to ensure that it is unobstructed.

Increase the heat dissipation area: If conditions permit, the heat dissipation effect of the transformer can be improved by increasing the heat dissipation area. For example, the number or area of the heat sink can be increased.

Use forced air cooling or water cooling: For high-power transformers, forced air cooling or water cooling can be used to improve the heat dissipation effect. This needs to be selected and designed according to the specific situation of the transformer.

6. Establish a perfect maintenance system

The life of the box-type transformer is not only related to the materials and insulation measures, but also to maintenance. In order to more scientifically extend the service life of the box-type transformer, a perfect maintenance system should be established. When formulating the maintenance system, it is necessary to consider the specific content and time limit of the maintenance of different parts of the box-type transformer. These can ensure that the box-type transformer can always maintain a good operating condition.
