Non-intrusive transformer on-line monitoring equipment

The utility model relates to non-intrusive transformer on-line monitoring equipment which comprises a box body, one end of the box body is provided with a first heat dissipation groove, the other end of the box body is provided with a second heat dissipation groove, the inner wall of the first heat dissipation groove is connected with a first heat dissipation fan in a sliding mode, and the inner wall of the second heat dissipation groove is connected with a second heat dissipation fan in a sliding mode. According to the utility model, external cold air is sucked in and blown to the inner wall of the heat dissipation chamber by controlling the operation of the first heat dissipation fan, meanwhile, the heat of the internal circuit board is conducted to the outer side by the heat dissipation fins, the cold air takes away the heat through the heat dissipation fins so as to carry out cooling, and meanwhile, the second heat dissipation fan operates so as to achieve the heat dissipation effect. And internal hot air
