为了检测分析500 kV全敞开式变电站作业场所的工频电场强度,研究人员利用PMM 8053A/PMM EHP-50C电磁场强度测试仪检测作业场所的工频电场,通过构建变电站平面坐标体系详细显示变电站工频电场强度的空间分布,并将检测结果与相关标准进行比较。结果显示,共检测554个作业点,500 kV配电装置区检测的296个作业点中,检测结果>10 kV/m的作业点有17个,≥5 kV/m、<10 kV/m的作业点有137个,220 kV、35 kV配电装置区及主
In order to test and analyze the power frequency electric field intensity at 500 kV full open substation work place, the researchers used the PMM 8053A / PMM EHP-50C electromagnetic field strength tester to test the power frequency electric field in the work place. By means of constructing the substation coordinate system, The spatial distribution of electric field intensity, and the test results with the relevant standards for comparison. The results showed that 554 operation points were detected. Among 296 operation points detected by 500 kV distribution area, there were 17 operation points with> 10 kV / m, ≥5 kV / m and <10 kV / m 137 operating points, 220 kV, 35 kV distribution area and the main equipment
