Analysis of No-load and Load Operation Characteristics of Single-phase Dual-winding Transformer

为研究变压器空载和负载运行时的物理过程及参数特性,本文根据空载运行下的磁电平衡关系以及负载运行下的磁势平衡关系,分别建立变压器空载和负载运行下的平衡方程式,并研究由方程式所反映出来的变压器空负载运行下的不同特性,为分析变压器运行特性提供依据。

In order to study the physical process and parameter characteristics of the transformer under no-load and load operation,this paper established the balance equations of the transformer under no-load and load operation ac⁃cording to the magnetic-electric balance relationship under no-load operation and the magnetic potential balance re⁃lationship under load operation,and studied the different characteristics of the transformer under no-load operation reflected by the equation to provide a basis for analyzing the operating characteristics of the transformer.
