Lõi thép dùng để dẫn từ thông . Để

Lõi thép dùng để dẫn từ thông . Để giảm tổn hao do dòng điện xoáy , lõi thép gồm nhiều lá thép mỏng 0,35-> 0,5 mm có sơn cách điện ghép lại gồm 2 phần :Trụ để đặt dây quấn và gông để khép kín mạch từ giữa các trụ
+ Dây quấn :thường bằng đồng hoặc bằng nhôm ,tiết diện tròn hay chữ nhật ,bên trong dây dẫn có bọc cách điện . Dây quấn gồm nhiều vòng dây và lồng vào trụ lõi thép . Giữa các vòng dây , giữa các dây quấn , và giữa dây quấn với lõi thép đều có cách điện .
Dây quấn có thể bố trí theo kiểu đồng tâm hay xen kẻ
Máy biến áp công suất nhỏ thường làm mát bằng không khí .Máy lớn được đặt trong thùng dầu , vỏ thùng có cánh tản nhiệt

The steel core is used to lead from pine. To reduce the loss caused by Eddy, the steel core is composed of many thin steel leaves 0.35-0.5 mm insulating paints > pair consists of two parts: Head to put the wire wrap and closed circuit to break these from between the head + Wire wrap: usually made of copper or aluminum, circular or rectangular cross-section, inside wire isolated. Wire wrap wire loops and multiple nested cylindrical steel core. Between the wire ring, between the windings, and between the windings with steel cores are insulated. Windings can be arranged radially, or alternated Small capacity transformers are often cooled by air. Large machines placed in oil barrels, the barrel shell radiator wings

Information on the use of steel core belt. In order to reduce the loss of current causes include many leaf shaped steel core steel 0,35 - > 1 mm thin coating composite power method includes two parts: column and handcuffs to the closed circuit between the rope to the postCopper or aluminum, round or rectangular cross section wire wrapped with rope, which has an electrical method. There are several circles of rope, and the rope is tied to the steel core of the pole. Between the circles of the rope, the rope tied to the rope tied, and with the steel core are electrically.A rope tied to a layout can be concentric or disturbed.Small power transformer cooling air.M y, usually set in large oil tank, the peel box wing radiator
