什么是铁损？
答：变压器的铁损又叫空载损耗，它属于励磁损耗而与负载无关，它不随负载大小而变化，只要加上励磁电压后就存在，它的大小仅随电压波动而略有变化。包括铁心材料的磁滞损耗、涡流损耗以及附加损耗三部分。空载损耗即不变损失。与通过的电流无关，但与元件所承受的电压有关。
空载损耗：当变压器二次绕组开路，一次绕组施加额定频率正弦波形的额定电压时，所消耗的有功功率称空载损耗。
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.
