摘要
为使室外景观照明的接地做法更加合理,阐述了接地形式的设置不应以距建筑物外墙20m为界,而应根据《建筑物电气装置第7-714部分:特殊装置或场所的要求户外照明装置》(GB 16895.28-2008)714.11条的规定及中压配电系统(10kV侧)的接地系统形式,确定室外景观照明的接地形式,应采用TT系统,提出当景观照明采用TT系统时其配电系统做法的建议。
In order to make the grounding practices for the outdoor landscape illumination more reasonable, the view that ground form set should not be bounded by 20m from building facades is elaborated. The grounding type of outdoor landscape illumination should be depended on the grounding type of the medium voltage system （10kV side） and according to the provision 714. 11 in GB 16895.28, and TT system is more reliable for the landscape illumination. The detailed practices of power distribution of TT system when it is used in landscape illumination are described.
