摘要
对重庆市110 kV、220 kV典型变电站站场外的工频电磁场进行实测并归纳总结了测量结果,根据测量得到的实际数据,得出变电站站场外工频电磁场的分布规律及变化趋势,表明变电站站场外工频电磁场均能满足相关规定要求,工频电磁场随主变容量的增大而呈增大趋势,随与主变距离的增加而减小,同时,户内变电站对工频电磁场的影响也比户外变电站要小。
Measuring the power frequency electric field of 110 kV,220 kV typical substations in Chongqing and summarizing its data resulting, this paper deduces the distribution law and changing trend of power frequency electric field of substations, h shows that power frequency electric field of substations can satisfy the requirements of relevant regulations, the power frequency electric field increases with the main capacity and decrease with the main distance. Meanwhile, indoor substances influence the power frequency electric field a bit less than outdoor substances.
