Transformatorning temir va mis yo'qolishi

When the primary winding of the transformer is energized, the magnetic flux generated by the coil flows in the core, because the core itself is also a conductor, in the plane perpendicular to the magnetic field lines will be induced potential, the potential in the cross-section of the core to form a closed loop and generate current, like a vortex so called "vortex". This "full current" increases the loss of the transformer and increases the temperature rise of the core heating transformer. The loss caused by the eddy current is called the iron loss.

In addition, a large number of copper wires are needed to wind the transformer. These copper wires have resistance, and when the current flows through, the resistance will consume a certain amount of power. This part of the loss is often consumed as heat, which is called "copper loss".

Shunday qilib, transformatorning harorati ko'tarilishi asosan temir yo'qotilishi va mis yo'qotilishidan kelib chiqadi. Transformatorda temir va mis yo'qotilganligi sababli, uning chiqish quvvati har doim kirish quvvatidan kamroq bo'ladi.

Ma'lumki, transformatorning temir yo'qotilishi transformatorning birlamchi kuchlanishiga bog'liq va ikkilamchi yuk bilan hech qanday aloqasi yo'q, ya'ni: transformatorda kuchlanish bor ekan, temir yo'qotish bo'lishi kerak. Muayyan kuchlanish ma'lum bir temir yo'qotilishini anglatadi. Misning yo'qolishi esa, asosan, yuk oqimiga bog'liq.
