Dry-type transformer with low noise and good heat dissipation

The invention discloses a dry-type transformer with low noise and good heat dissipation, which comprises a transformer body, a shell, a cooling device, a sliding device and a controller, the transformer body is connected with the shell through a sliding device; the cooling device is mounted on one side of the shell; the controller is located outside the cooling device; the cooling device comprises a cooling water tank, a cooling machine shell, a circulating pipeline, a mute water pump and a temperature sensor. The cooling water tank is installed outside the shell, and the cooling machine shell is installed on the outer side of the transformer body. One end of the circulating pipeline is connected with the cooling water tank through the mute water pump, and the other end is connected with the cooling shell; the temperature sensor is located in the cooling water tank and the cooling machine shell and connected with the controller. The controller is connected with the outer side of the cooling water tank; coolin
