I. Definition
Transformer oil tank is a container for holding the transformer body and transformer oil.
II. توابع اصلی
1. Oil filling, heat dissipation, base, transportation;
2. Protective insulation: Isolates the insulation from the atmosphere to prevent moisture and gas absorption, thereby avoiding oil aging;
3. Drying insulation: It functions as a vacuum chamber during vacuum extraction at ambient temperature.

There are two basic types of oil tank for oil-filled transformer: barrel type and bell type.
1. The drum-type oil tank consists of two parts: the tank cover and the drum body. Its advantages include a simple appearance, requiring only a small amount of oil for lifting; the disadvantage is that for large-capacity transformers, on-site maintenance requires a crane with sufficient lifting capacity.
2. The bell-type oil tank consists of an upper section and a lower section. Its advantages and disadvantages are opposite to those of the drum-type oil tank.
I. Definition
The core and coils of different voltage levels are assembled together, equipped with a clamping device, and lead wires are welded to form a complete unit, known as the transformer body.
2. سفت شدن بدنه ترانسفورماتور
1. The radial tightening of coils is a method to maintain the concentric position between coils and the core, as well as between coils themselves. Additionally, the internal coils are subjected to compressive forces when experiencing radial short-circuit electromagnetic mechanical forces, necessitating a robust support point. بنابراین، سفت شدن شعاعی سیمپیچهای داخلی در ترانسفورماتورهای{4} با ظرفیت بالا از اهمیت بالایی برخوردار است.
توجه: «سفت کردن سیم پیچ شعاعی» به فرآیندی در ساخت ترانسفورماتور اشاره دارد که در آن سیم پیچ ها به طور ایمن به صورت شعاعی (از مرکز به سمت بیرون) لنگر می زنند تا از شل شدن، تغییر شکل یا ناهماهنگی جلوگیری شود.
2. The reliability of transformer manufacturing quality depends largely on the axial fastening of the coil, which can resist the action of axial electromagnetic mechanical force during short circuit and eliminate the looseness of the coil.
