中だけファンを稼動するようにしたものもある。Conventional technology Conventional dry cooling systems for transformers use air to cool them. For small-capacity transformers, a self-cooling dry system that relies on air convection and natural heat dissipation from the transformer surface is used. For large-capacity transformers, a fan is attached to the bottom of the coil to forcefully blow air into the transformer to cool it. Usually, waste heat from transformers is not recovered. In the case of a transformer equipped with a fan, multiple fans are installed below the coil to improve cooling efficiency and to ensure that even if one fan fails, it will not have a significant impact on the overall system. . The lifespan of a fan is shorter than that of a transformer, so it must be replaced regularly, and some systems only operate the fan during the day if the load changes significantly between daytime and nighttime. .
