Heat pipe cooling dry-type transformer

Abstract

The invention discloses a heat pipe cooling dry-type transformer. The transformer comprises an iron core, a low-tension coil and a high-tension coil which are arranged on the iron core, the outer sides of the upper end and the lower end of the iron core are fixed with clamping pieces, and the iron core, the low-tension coil, the high-tension coil and the clamping pieces are arranged inside a transformer box body. The transformer is characterized in that the high-tension coil is connected with a high pressure control cabinet, a microcontroller and a transformer temperature controller are arranged on the transformer box body, and the transformer temperature controller is connected with the microcontroller; the iron core is fixed with a superconductivity heat pipe, a voltage transformation system circuit is arranged in the high pressure control cabinet, the voltage transformation system circuit comprises a high-voltage outgoing line circuit and a high-voltage incoming line circuit, and the high-voltage outgoing line circuit and the high-voltage incoming line circuit are connected with each other. The heat pipe cooling dry-type transformer has the advantages that the temperature of thehighest point of the transformer is reduced by the heat pipe, the iron core has a maximum temperature in the whole dry-type transformer, a heat dissipating air passage and the superconductivity heatpipe are installed on the original iron core structure, thereby the heat dissipating effect of the iron core is far better than that of the original iron core, the temperature of the iron core with the highest temperature of the transformer can be reduced in time, and therefore the temperature of the whole transformer can be reduced.

Description
