The invention discloses a
transformer cooling device. The device comprises a shell, a fan and a filter box are fixedly connected to the two sides of the top of an inner cavity of the shell correspondingly, a first filter screen is fixedly connected into the filter box, the right side of the bottom of the filter box communicates with a dry cooler through a pipeline, an air inlet cover and an air outlet cover are fixedly connected to the two sides of the dry cooler correspondingly, and a first motor is fixedly connected to the left side of the air inlet cover. According to the invention, by arranging the fan, the filter box, the first filter screen, the dry cooler, the air outlet cover and an air outlet hole, hot air can be refrigerated, and then the interior of the
transformer is cooled; and by arranging the air inlet cover, an air inlet hole, a fixing block, a water tank, a second filter screen, a first connecting
pipe, a water pump, a second connecting
pipe, a water outlet hole and awet film, air can be humidified, the
transformer cooling device is convenient to use, the interior of the transformer can be rapidly cooled through the transformer cooling device, the service life ofthe transformer is prolonged, and use of people is facilitated.
