Dry-type transformers are indispensable and important equipment in power systems. Their lifespan and scrap time are key factors in the safe operation and economic benefits of power systems. So, how long is the lifespan of dry-type transformers?
How long do dry type transformers last?
Dry-type transformers are commonly used in power systems. Their service life and replacement cycle will directly affect the stable operation of the power system. The general service life of dry-type transformers is about 15-20 years, but some dry-type transformers can be used for more than 30 years. The service life of dry-type transformers is related to factors such as their quality, design, and manufacturing. In actual use, the life of dry-type transformers is also related to factors such as their load conditions and the use of protective devices.
Factors affecting the service life of dry-type transformers
1.Service life:
Transformers that have been in operation for a long time, especially those that have been in use for 10 years or more, may experience aging of components such as windings and cores, and reduced insulation performance, which will affect their capacity output and life.
2.Operating environment:
The working environment of dry-type transformers has an important impact on their service life. Transformers should be installed in dry, well-ventilated places to avoid moisture and high temperatures. At the same time, the altitude of the transformer’s working area will also affect its heat dissipation capacity, thereby affecting its service life. In areas with higher altitudes, due to the relatively low atmospheric density, the heat dissipation capacity of the transformer will be weakened, thereby shortening its service life.
3.Load change:
The load condition of dry-type transformers is also a key factor affecting their service life. Long-term overload operation will cause the transformer to overheat, accelerate the aging of the insulation material, and thus reduce its service life. Therefore, when using dry-type transformers, ensure that their load is within the rated range to avoid overload operation.
4.Fault repair:
After a fault repair, the internal structure and performance of the transformer may change. A capacity test is required to ensure that it meets the requirements.
Measures to extend the service life of dry-type transformers
In order to extend the service life of dry-type transformers, we can take the following measures:
1. Ensure that the dry-type transformer is in a dry, well-ventilated environment to avoid moisture and high temperature. When used in high altitude areas, pay special attention to heat dissipation.
2. Avoid long-term overload operation of dry-type transformers and ensure that their load is within the rated range. During peak power consumption, the load should be arranged reasonably to avoid overload operation.
3. Regularly clean the dry-type transformer, check whether the fasteners and connectors are loose, and check the aging of the insulating material. Through regular maintenance, potential safety hazards can be discovered and dealt with in a timely manner.
4. When choosing a dry-type transformer, you should give priority to well-known brands and high-quality products. High-quality products have better design and manufacturing quality and longer service life.
