摘　　要：工频电磁场超过一定限值时可能会对人体产生潜在的危害。变电站作为电力系统中一次设备和二次设备最集中的场所,随着电压等级的提高变电站的电磁环境更为恶劣。对500kV高压变电站的工作走廊进行工频电磁场测试,得出了高压变电站中工频电磁场的分布情况。对高压变电站现有屏蔽服的屏蔽效能进行了实验,对现有屏蔽措施进行了分析和建议。There is a public debate that is the power frequency electromagnetic field exceeds a certain limit may be a potential hazard to the human health. As the substation is the most concentrated place of the substation primary equipment and secondary equipment in a power system, and the electromagnetic environment become worse with the voltage level improving. In this paper, the industrial -frequency electromagnetic field of two 500kV high voltage substation corridors have been tested, and their distribution have been made, too. An experiment has been done on the effect of the high-voltage substation shielding; some advice about the shielding measures was given as well.
