The invention discloses an intelligent oil-immersed power transformer. The intelligent oil-immersed power transformer comprises a casing, a fan controller, a heat dissipating fan, an annular oil pipeline, an oil tank, corner guards, shock pads, a dampproof board, an oil strainer tank, a filter screen, an oil outlet pipeline, an oil inlet pipeline, an oil pump, a transformer body and heat dissipating holes and is characterized in that the corner guards are arranged at corners of the bottom of the shell. According to the intelligent oil-immersed power transformer, the corner guards are used for preventing internal components of the transformer from being damaged by collision during transportation; the shock pads are used for reducing the damage to the transformer caused by vibration; the dampproof board is used for reducing the influence on the internal components caused by water and preventing the short circuiting or other faults of an internal circuit caused by ground water logging; meanwhile, the fan controller is added, and an intelligent circuit is adopted to carry out control and can be used for indicating the condition of too low voltage, so that the damage to a heat radiator and a computer caused by long-time low-voltage operation is prevented; the intelligent oil-immersed power transformer is simple and convenient, is simple in structure and convenient in use, has a very high market value and is beneficial to popularization.
