What Is The Production Process Of Oil-immersed Transformers?

‌The production process of oil-immersed transformers mainly includes the following steps‌:

‌Preparation phase‌: Before starting manufacturing, sufficient preparation is required. Select suitable materials such as silicon steel sheets, insulating paper and transformer oil, and prepare the required manufacturing equipment and tools. In addition, technical preparation is required to determine the specifications, parameters and design of the transformer‌

‌Coil production‌: The coil is the core part of the transformer, and its quality directly affects the performance of the transformer. Coil production includes 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 stages heat and impregnate the coil to enhance its insulation performance; finally, the electrical performance of the coil is ensured to meet the design requirements through testing‌

‌Core production‌: The core is another key component of the transformer, which is used for magnetic and electrical conduction. Core production includes cutting, stacking, tightening and testing. In the shearing stage, the silicon steel sheets need to be sheared according to the design requirements; in the stacking stage, the sheared silicon steel sheets are stacked in order; in the fastening stage, 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. ‌

 
‌Body assembly‌: Body assembly includes the assembly of coils, cores and other parts. During the assembly process, the process parameters and operating procedures must be strictly controlled to ensure the assembly quality. In addition, various tests and inspections, such as electrical performance tests and mechanical strength tests, are required to ensure that the product meets the design requirements. ‌
‌Oil tank and accessories production‌: Oil-immersed power transformers require the use of oil tanks and other accessories, such as radiators, valves, etc. The production of these accessories also requires strict control of process and quality to ensure that they can meet the operating requirements of the transformer. At the same time, these accessories must also be tested and inspected to ensure that their performance is stable and reliable. ‌
‌General assembly and testing‌: The last step is general assembly and testing. General assembly is to assemble all parts together to form a complete oil-immersed power transformer. In this process, the assembly process and quality must be strictly controlled to ensure the performance and reliability of the product. ‌
