新型节能配电变压器的经济性分析及选型建议（Economic Analysis and Application Advice onthe New Types of Energy-Saving Distribution Transformer ）
配电变压器 节能 应用研究
2010/8/17
S13型、S14型和非晶SBH15型变压器都是非晶合金变压器，是具有节能效果的变压器新产品。文章分析了这些变压器的损耗特性，并采用TOC法比较其技术经济性。从与S11型变压器比较的结果可知，非晶SBH15型的空载损耗最低，S13型变压器的负载损耗最低，因此，在使用这些变压器替换已有的变压器时，要根据变压器的用途和费用加以选型。
SF6 新气痕量杂质气相色谱分析新方法与电力行业SF6 新气推荐标准（A New Trace Impurity Gas Chromatography Analysis Method for SF6 New Gasand Recommended Standard of SF6 New Gas for Electric Power Industry）
