A method for assembling a transformer body and the structure of the transformer body

Abstract

The invention discloses a method for assembling a transformer body. The method comprises the first step of preparing an iron core, the second step of arranging an installing track on the iron core according to a gap between the iron core and a coil, the third step of arranging the coil on the iron core in a sleeved or winding mode, the fourth step of installing a fastening device with a groove between the iron core and the coil along the installing track, the fifth step of injecting a curing agent from the groove of the fastening device until all gaps of the groove of the fastening device is filled with the curing agent, the sixth step of finishing assembling after the curing agent is completely dried and solidified. According to the method for assembling the transformer body, the coil and the iron core can be effectively prevented from relative loosening when transformer products are transported or operated, the safety and reliability of a transformer are ensured; the transformer body structure is especially suitable for a transformer with a three-dimensional roll iron core or an amorphous alloy structure, and the requirement for fastening between the iron core and the coil of the transformer with the three-dimensional roll iron core and the amorphous alloy structure is met.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a transformer body assembly method and a transformer body structure thereof. Background technique [0002] Iron core and coil are important core components of transformers, and their performance directly determines the performance of transformer products. However, during the transportation or operation of the transformer, the iron core and coil are prone to loosening. In order to ensure the safety and reliability of transformer products, the iron core and coil It must be completely fastened and reliable without relative looseness. In the traditional transformer body structure, most of them use insulating stays inserted in the gap between the iron core and the coil. The disadvantage of this is that the stays directly squeeze the iron core. And coils, which may eventually lead to damage to the core and coils and affect the performance of the transformer, especially high-voltage, large-c...

[0002] Iron core and coil are important core components of transformers, and their performance directly determines the performance of transformer products. However, during the transportation or operation of the transformer, the iron core and coil are prone to loosening. In order to ensure the safety and reliability of transformer products, the iron core and coil It must be completely fastened and reliable without relative looseness. In the traditional transformer body structure, most of them use insulating stays inserted in the gap between the iron core and the coil. The disadvantage of this is that the stays directly squeeze the iron core. And coils, which may eventually lead to damage to the core and coils and affect the performance of the transformer, especially high-voltage, large-capacity products, or products with special structures and materials, such as 110kv and above voltage level products, three-dimensional wound core structure or non- Crystal alloy products, etc., its special performance makes the requirements for the transformer body higher, and the particularity of the wound core structure makes the iron yoke and the core column connected together, so that the gap between the core column and the coil at the lower part of the iron yoke cannot be inserted into the stay. , the particularity of the material of the amorphous alloy itself cannot be subjected to the compression force of the stay, so the traditional transformer body structure cannot meet the requirements and needs to be further improved and optimized
