220 kV变电站电磁环境实测分析

Analysis of Actual Measurement of Electromagnetic Environment of 220 kV Substations

对佛山市区21座220 kV变电站的电磁环境进行了普查,归纳分析了典型结构的220 kV变电站工频电磁场水平。测量结果表明,220 kV变电站工频电磁场强度完全符合相关环保标准要求,站界电磁场强度距标准限值还有相当大裕度,不会对周边居民及站内长期工作人员的健康造成影响。

Based on the general investigation of twentyone 220 kV substations located in the urban district of Foshan city, the power frequency electromagnetic field levels of the 220 kV substation with typical structure are analyzed. Measurement results show that the strengths of power frequency electromagnetic field within 220 kV substations perfectly confirm to relative environmental standards; there are sizable margins between the electromagnetic field strengths at the borders of the 220 kV substations and the standard limit values, so the electromagnetic field strength of 220 kV substations will not affect the health of both substation working personnel in substations and neighboring inhabitant.
