| 摘 要： | 对110kV分级绝缘变压器中性点保护障隙配置进行了分析，认为低压侧无地方电源介入的100kV变电所内的主变压器中性点不应加装棒间隙。针对已运行的不同型式的中性点避雷器，保护零序电抗与正序电抗的实际比值，进行了配合校验。

| Abstract: | Based on the configuration analysis of neutral point for 110 kV graded insulation transformer, this paper suggested that protective gap should not be installed at neutral point of 110 kV transformer where no power plant is available at low voltage coils. According to different existing run time X 0/X 1 values,neutral point and surge arrester have been tested to be matched. |
