The invention discloses a drying method of a high-voltage transformer for electric dust removal. The method includes four stages of preheating, transition, main drying and final drying. It adopts the vacuum drying method of variable pressure. After the temperature of the transformer coil rises to the first preset temperature, vacuumize the drying tank and continue the deep pumping stage for 1.5-2.5h”, and formulate the most suitable drying stages for high-voltage transformers for electrostatic precipitator according to research and actual operation time interval; after adopting the drying method provided by the present invention, it only takes 18 to 25 hours to dry a furnace of high-voltage transformer, the drying time is short, energy is saved, the production cycle of the transformer is shortened, the production efficiency is improved, and the drying effect is good. It can meet the insulation requirements of high-voltage transformers for dust removal. In addition, the moisture in the drying tank will not condense on the iron core, which can prevent the iron core from rusting.
Description
technical field [0001] The invention relates to the field of drying of transformers, in particular to a drying method of high-voltage transformers for electric dust removal. Background technique [0002] Transformer is a commonly used voltage transformation device, which is mainly composed of iron core, coil and insulating material assembly. After the transformer is assembled and before the transformer oil is added, it is usually dried to remove the moisture in the insulating material and control the moisture content within the limit required by the product quality to ensure that the transformer has sufficient insulation strength and operating life. [0003] The transformer used for electrostatic precipitator is usually a high-voltage transformer, which has the characteristics of using relatively few insulating parts and requiring a high level of insulation. At present, the drying process of high-voltage transformers for electrostatic precipitator mostly follows the releva...
