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)
SF6新气 痕量杂质 色谱方法 标准
2010/8/17
介绍了一种SF6新气痕量杂质气相色谱分析的新方法。与DL/T 920—2005《六氟化硫中空气、四氟化碳的气相色谱分析方法》相比较,新方法可以从SF6新气中检出更多的痕量杂质,甚至多达17种,且方法高度智能化并便于普及。考虑到SF6新气中某些杂质会影响有关电力设备的使用寿命,提出了电力行业SF6新气推荐标准的方案。
