摘要
变压器损耗是现代物理学领域的概念,是指空载损耗P0和短路损耗Pk之和。空载损耗P0:当用额定电压施加于变压器的一个绕组上,而其余的绕组均为开路时,变压器所吸收的有功功率叫空载损耗。短路损耗Pk:对双绕组变压器来说,当以额定电流通过变压器的一个绕组,而另一个绕组短接时变压器所吸收的有功功率叫做变压器的短路损耗。而变压器的附加损耗直接影响变压器的运行效率和电网的经济效率。
Transformer loss is the concept of modern physics field no-load loss,refers to the sum of P0 and short-circuit loss Pk.No-load loss P0：when using the rated voltage applied on a winding transformer,and the rest of the winding transformer are absorbed by,when open the active power that no-load loss.Short circuit loss Pk：on the double winding transformer with rated speaking,when an electric current through the transformer windings,while another winding transformer is absorbed when short-circuited the active power consumption.And transformer additional loss directly affect the operation efficiency and power transformer the economic efficiency.
