Abstract

The invention discloses a dry-type-transformer heat dissipation system. The dry-type-transformer heat dissipation system comprises a shell, an iron core is arranged in the shell, a low-voltage coil pouring body is arranged on the outer side of the iron core, a high-voltage coil pouring body is arranged on the outer side of the low-voltage coil pouring body, an insulating cylinder is arranged between the low-voltage coil pouring body and the high-voltage coil pouring body, a first servo motor is arranged at the upper end of the high-voltage coil pouring body, a second servo motor is arranged at the lower end of the high-voltage coil pouring body, a first fan blade and a second fan blade are arranged on the first servo motor and the second servo motor respectively, the diameter of the first fan blade is smaller than the outer diameter of the low-voltage coil pouring body and larger than the inner diameter of the low-voltage coil pouring body, and the diameter of the second fan blade is larger than the outer diameter of the high-voltage coil pouring body. The invention also discloses a heat dissipation control method of the dry-type-transformer heat dissipation system. By means of the dry-type-transformer heat dissipation system and the heat dissipation control method thereof, the defects of the prior art can be overcome, and the heat-dissipation uniformity of a transformer is improved.

Description

technical field [0001] The invention relates to the technical field of dry-type transformers, in particular to a heat dissipation system of a dry-type transformer and a heat dissipation control method thereof. Background technique [0002] As one of the major equipment for power transmission and transformation, the transformer will generate power loss during operation due to the current flow of each coil conductor and the existence of electromagnetic field, mainly load loss, no-load loss and additional loss. These losses will be converted into heat transfer to the surrounding medium, causing the transformer to heat up and increase in temperature. However, with the increase of transformer capacity, the leakage magnetic flux increases, and the corresponding stray loss increases; the increase in transformer size and capacity is not proportional to the increase in local stray loss; large-capacity transformers have large currents, especially the parallel wires of low-voltage wind...
