10kV线路用多腔室间隙防雷装置工频续流遮断能力选择建议
|
摘要
我国10 kV架空配电线路近年来安装使用了一些多腔室间隙防雷装置,由于相关研究未及时跟进,多腔室间隙产品的额定遮断工频续流值这一关键参数的选择目前缺乏理论依据。通过建立线路短路故障计算模型,结合典型多腔室间隙产品的试验数据,计算获得不同故障情况下通过多腔室间隙的实际电流,再结合线路工程防雷需求,提出对用在有连续建筑物或绿化树木屏蔽的城区线路(段)上的多腔室间隙产品,额定遮断工频续流峰值短期可选择不小于1kA,远期应选择不小于1.5 kA,对用于空旷地区的线路(段)上的多腔室间隙产品,额定遮断工频续流峰值短期可选择不小于5 kA,远期应尽可能选择更高的遮断续流水平,并进一步给出了安装使用建议。
In recent years, number of multi-chamber gap lightning protection devices are installed in some 10 kV overhead distribution lines in China. Due to insufficiency of relevant research, selection of key parameters for rated interrupted power frequency follow current of the multichamber gap products currently lacks theoretical basis. This paper establishes a short-circuit fault calculation model and,combining experimental data of typical multi-chamber gap products, calculates actual currents through the multi-chamber gap under different fault conditions. Combined with the lightning protection requirements of 10 k V line project,following suggestions are proposed: for the multi-chamber gap products used on urban lines shielded with objects or green trees, the short-term rated interrupted power frequency follow current not less than 1 kA can be selected, and for long-term application, not less than 1.5 k A should be selected; for the multi-chamber gap products used on the lines in open areas, the short-term rated interrupted follow current not less than 5 k A can be selected, for long term application, higher interrupted follow current level should be selected as far as possible.Suggestion for installation and usage are also provided.
