| 摘 要： | 测量了东北某变电站中 2 2 0、5 0 0kV设备区工频电磁场分布规律和变化趋势 ,结果表明站内电场和大部分磁场强度均低于ICNIRP限值 ,有些地方 (主要是电抗器 )周围磁场较大 ,虽短距离内迅速衰减 ,亦应引起注意

| Abstract: | Power frequency electric & magnetic field (PEMF) measurement in a 500 kV air insulated substation has been conducted. The distribution of power frequency electric & magnetic field along certain routes and the magnitudes beside equipment are reported. The measurement results are compared with the guidelines in standards. The results show that the values of PEMF accord with the guidelines of ICNIRP, but the values of electric field in 500 kV equipment area and magnetic field around reactor exceed the guidelines of national standard, which should be paid attention in electric power industry. |
