摘要
提出了在10kV变配电系统中,依据10kV电力系统三种不同接地方式,如何选择无间隙氧化锌(ZnO)避雷器的额定电压问题。对该型避雷器的特征以及10kV系统三种接地方式的特性及使用情况作了论述。
Based on three different grounding types for 10 kV power system, the problem on how to select the rated voltage of gapless zinc oxide （ZnO） lightning arrester in the 10 kV power supply and distribution system is proposed. In addition, the characteristics of this type of lightning arrester and the features of three grounding types for 10 kV system and the application have been discussed.
