Abstract
The invention relates to an inductive ventilation cooling system of an indoor split type transformer, comprising a transformer chamber and a radiator chamber which are adjacent, wherein an oil collecting chamber is arranged below the transformer chamber and a cable chamber is arranged below the radiator chamber. The inductive ventilation cooling system is characterized in that an air guide sleeve is arranged above a radiator in the radiator chamber and an inductive ventilation device is arranged in the cable chamber below the radiator chamber. In the invention, the air guide sleeve is arranged above the radiator in the radiator chamber to ensure that an air-inlet flow wraps the lower part and the periphery of the radiator and orderly flows from bottom to top and the contact between air and the surface of the radiator is increased; in the mean time, the hot-pressing difference and the flow velocity and the air-inlet volume of the air are increased so as to increase the radiating coefficient of the surface of the radiator and improve the radiating capability; and therefore, safe operation of the transformer is guaranteed and safe power supply reliability of a power grid is increased. At extreme high-temperature time period in summer, temperature difference is applied to control of starting and stopping of a draught fan, and the ventilation cooling of the radiator is increased through two air flows of natural ventilation and mechanical ventilation so as to improve heat-radiating capability.
