Abstract

The invention relates to a dry-type transformer overheating early warning method and device, computer equipment and a storage medium. The method comprises the steps: acquiring multiple items of firsthistorical load data and second historical load data with the generation time after the first historical load data; performing correlation analysis on the first historical load data, and screening outthird historical load data having correlation with the second historical load data from the first historical load data; inputting the third historical load data into a target load prediction model toobtain target predicted load data in a future preset time period; obtaining environment prediction temperature data in a future preset time period, and inputting the target prediction load data and the environment prediction temperature into the hot spot temperature calculation model to obtain hot spot temperature distribution of the dry-type transformer in the future preset time period. According to the invention, overheating early warning can be carried out on the dry-type transformer in operation, and corresponding protection measures can be taken for the transformer in time according to an overheating prediction result.

Description

technical field

[0001] The present application relates to the technical field of electrical detection, in particular to a dry-type transformer overheating warning method, device, computer equipment and storage medium. Background technique

[0002] Dry-type transformers have good fire performance, so they are widely used in local lighting, residential quarters, high-rise buildings or public places and other places with high fire protection requirements. However, for the vast majority of dry-type transformers, due to the uneven temperature distribution during operation, the temperature will reach the highest point during a certain period of time during operation, that is, the highest temperature in the equipment, which is the hottest point (The hottest point is used to measure the thermal limit value of the maximum load capacity of dry-type distribution transformers). When the hot spot temperature of the dry-type transformer reaches the hottest point, it is easy to cause over...
