High-temperature sensing type circulating water-cooled transformer

Abstract

The invention discloses a high-temperature sensing type circulating water-cooled transformer, and belongs to the technical field of transformers, preliminary contact type cooling treatment is realized by arranging water cooling boxes loaded with water cooling liquid on the left side and the right side of a transformer body, a plurality of water cooling bodies are distributed on the joint surfaces of the water cooling boxes and the transformer body, and cooling liquid is stored in the water cooling bodies; the water cooling bodies are communicated with the interior of the transformer body through the vent holes, the heat transfer effect is further improved, after the temperature in the transformer body rises, a temperature sensing deformation trigger located in a heat conduction ball senses the high temperature to enable a sealing bag to block the vent holes, and a micro circulating pump and a semiconductor chilling plate are triggered and started so cooling liquid in the water cooling bodies flows circularly and meanwhile, the semiconductor chilling plate is used for cooling the water cooling liquid, the cooling liquid transmits heat in the transformer body to the water cooling box for cooling, and the circulation is carried out, so that automatic circulating flow after high-temperature sensing is effectively realized, and high-efficiency cooling is carried out.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a high-temperature-sensing circulating water-cooled transformer. Background technique [0002] A transformer is a static electrical device used to transform AC voltage and current to transmit AC power. It realizes power transfer based on the principle of electromagnetic induction. A device that uses the principle of electromagnetic induction to change AC voltage is an important part of the power supply system. component. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers according to their uses. [0003] The transformer is generally installed in the transformer box. Since the electronic components inside the transformer will emit a lot of heat during the working process, once the heat cannot be removed in the transformer box in time, the high temperature of the transformer will definitely affect t...

[0003] The transformer is generally installed in the transformer box. Since the internal electronic components of the transformer will emit a lot of heat during the working process, once the heat cannot be removed in time in the transformer box, the high temperature of the transformer will definitely affect the normal operation of the transformer.
