摘　　要：负载损耗是变压器工作效率的重要指标,也是变压器的关键性能指标之一,对评价变压器的质量具有重要的参考价值。本文作者针对配电变压器一次侧状态变量测量困难、成本较高的情况,通过对变压器本身参数进行分析,建立一种变压器负载损耗的标准计算模型,该方法仅需在配电变压器二次侧测得相关变量即可计算出变压器负载损耗。最后通过仿真进行验证分析,将仿真得到的二次侧测量值代入所建立的标准数学模型中并与实际值进行对比,结果表明该方法在计算负载损耗方面准确率较高。Load loss is an important indicator of transformer efficiency and one of the key performance indicators of transformers,which has important reference value for evaluating the quality of transformers.This article focuses on the difficulty and high cost of measuring the state variables on the primary side of low-voltage distribution transformers.By analyzing the parameters of the transformer itself,a standard calculation model for transformer load loss is established.This method only needs to measure the relevant variables on the secondary side of the distribution transformer to calculate the transformer load loss.Finally,validation analysis was conducted through simulation,and the simulated secondary side measurement values were substituted into the established standard mathematical model to compare with the actual values.The results showed that this method has high accuracy in calculating losses.
