摘要
对新标准GB20052—2020要求的能效限定值进行了介绍,针对新旧标准关于变压器的空载损耗和负载损耗的允许限值进行比较,通过计算给出了在经济运行的条件下合理确定变压器运行方式以及能耗对比分析,给出了在不同负荷情况经济运行和不同运行方式时变压器损耗的计算数据,为工程设计时合理确定变压器容量及运行方式提供参考。
This paper introduces the minimum allowable value of energy efficiency required by GB 20052-2020,and compares the allowable limits of no-load loss and load loss of transformer between the old and new standards.The reasonable determination of transformer operation mode and the energy consumption comparison analysis under the condition of economic operation through calculation are given.The calculation data of transformer loss under different load conditions and different operation modes are given, which provides a reference for reasonably determining the transformation capacity and operation mode in engineering design.
