摘要
为了了解500 kV变电站电磁污染分布特性,利用EFA-300电磁场强分析仪对变电站内500 kV配电区、220 kV配电区、变电站主要设备及变电站周边不同类型环境的工频电场强度与磁感应强度进行检测,从中找出其工频电磁场污染分布特性。共检测92个测点,结果显示电场强度、磁感应强度均在允许范围内。但是,变电站的个别设备附近电场强度接近职业标准限值,做防护措施时需重点关注。
In order to understand 500 kV substation electromagnetic pollution distribution characteristics,EFA-300 electromagnetic field strength analyzer was used to measure the power frequency electric field intensity and magnetic field strength in different regions,including 500 kV area,220 kV area,main equipments area and surrounding area.The results of 92 measurement points showed that all data from the measurement were allowed by the standard.However,the electric field intensity around certain equipments almost reached occupational standard limits,which should pay more attention in precaution.
