什么是鐵損？
答：變壓器的鐵損又叫空載損耗，它屬于勵磁損耗而與負(fù)載無關(guān)，它不隨負(fù)載大小而變化，只要加上勵磁電壓后就存在，它的大小僅隨電壓波動而略有變化。包括鐵心材料的磁滯損耗、渦流損耗以及附加損耗三部分?？蛰d損耗即不變損失。與通過的電流無關(guān)，但與元件所承受的電壓有關(guān)。
空載損耗：當(dāng)變壓器二次繞組開路，一次繞組施加額定頻率正弦波形的額定電壓時(shí)，所消耗的有功功率稱空載損耗。
What is the iron loss?
Answer: Transformers iron loss and no-load loss, which belongs to the excitation lossand is independent of the load, it does not change as the load changes, as long asthere is with the excitation voltage, it is only the voltage fluctuation and slightlychanges. Includes the core material hysteresis loss, eddy current loss and additional loss of three parts. No load loss that is invariant loss. Has nothing to do with the current, but with the element of the withstand voltage of.
When the transformer no-load loss: two secondary winding, a winding rated voltageapplied rated frequency sine wave, the active power consumed is called no-load loss.
