Key process details of distribution transformer:
Core production: including cutting, stacking, fastening and testing. In the cutting process, the silicon steel sheets need to be cut according to the design requirements; in the stacking process, the cut silicon steel sheets are stacked in sequence; in the fastening process, the stacked silicon steel sheets are fastened with fasteners; finally, the electrical performance of the core is ensured to meet the design requirements through testing
Coil production: including winding, drying, impregnation and testing. When winding, the wire needs to be wound around the skeleton according to the design requirements; the drying and impregnation process requires heating and impregnation of the coil to enhance its insulation performance; finally, the electrical performance of the coil is ensured to meet the design requirements through testing.
Oil immersion treatment: Oil immersion can not only effectively cool the transformer, but also improve insulation performance and reduce losses. During the oil immersion process, attention should be paid to key steps such as temperature control and vacuum treatment to ensure that the oil immersion effect is optimal.
