Radiating capacity evaluation method and device of radiator and storage medium

Abstract

The invention relates to the technical field of electric power, and discloses a heat dissipation capacity evaluation method and device of a radiator and a storage medium. The heat dissipation capacityevaluation method comprises the steps: collecting the oil inlet temperature and the oil outlet temperature of the radiator in real time, calculating the difference value of the oil inlet temperatureand the oil outlet temperature, and acquiring the temperature difference change rate of the radiator; and evaluating the heat dissipation capability of the radiator according to the temperature difference change rate. According to the embodiment of the invention, the temperature difference change rate of the radiator is calculated through an actual measurement method, the heat dissipation capacityof the radiator is evaluated according to the temperature difference change rate, and compared with a method based on the experience of technicians and infrared temperature measurement, the method reduces the working intensity of the technicians, improves the automation degree, and can also reduce the waste of resources.

Problems solved by technology

[0002] When the ambient temperature is high or the load is heavy, the oil-immersed self-cooling transformer often cannot dissipate the heat quickly through the radiator, resulting in high oil temperature and insufficient output capacity of the transformer.

[0003] In order to effectively dissipate the heat generated by the windings and iron core inside the transformer, water cooling or air cooling is generally used to enhance the heat dissipation effect of the radiator, but currently th
