Main transformer oil flow guide microcirculation device with photovoltaic frequency conversion function and application method thereof

The invention relates to a main transformer oil flow guide microcirculation device with a photovoltaic frequency conversion function and an application method thereof. The device comprises a main transformer body and radiators arranged on the two sides of the main transformer body. An oil flow guide nozzle tube is arranged under a winding and an iron core, the winding and the iron core are arranged in the main transformer body, the side, facing the winding and the iron core, of the oil flow guide nozzle tube is evenly provided with oil outlet holes, a variable frequency microcirculation pump is electrically connected with a power supply controller, the power supply controller is connected with an energy storage, and the energy storage is connected with a solar energy receiver through a photoelectric converter. The device overcomes the defects of an existing main transformer oil flow circulating mode. A photoelectric conversion system receives solar energy and carries out photovoltaic conversion and power supp
