摘要
为了促进我国电磁场控制限值国家标准的出台,针对输变电工程的工频电场和磁场,介绍了世界卫生组织推荐的国际非电离辐射防护委员会(ICNIRP)导则和电气与电子工程师学会(IEEE)标准在电磁场基本限值、参考水平以及最大允许曝露等方面的规定和变化,比较分析曝露限值的应用原则、制定依据及防护措施,由此提出对我国电磁场控制限值的具体建议,得到结论:IEEE标准较ICNIRP导则更多地考虑了具体工程环境下的限值处理问题;用参考水平或最大允许曝露来确定是否符合或者超过基本限值;建议国家标准同时采用4kV/m和10kV/m两个电场控制限值,保留100μT作为磁场控制限值。
For the issuance of national standard on control limits of electric and magnetic fields, the regulations and their variations on such aspects as basic restrictions, refer- ence levels and maximum permissible exposure of electric and magnetic fields in the International Commission on Non- Ionizing Radiation Protection (ICNIRP) guidelines and The Institute of Electrical and Electronics Engineers (IEEE) standard recommended by World Health Organization are introduced as regard to power frequency electric and mag- netic fields produced by power transmission and transforma- tion engineering in the paper. Then, application principles, development basis and the corresponding protective meas- ures of these exposure limits are compared, and the detailed suggestions for developing national standard on control limits of electric and magnetic fields are put forward. The conclu- sions are drawn that the limits under the specific project en-vironment are more considered in IEEE standard than that in ICNIRP guidelines, the reference levels or maximum per- missible exposure could be applied to determine whether the basis restrictions are satisfied or not, and the control limits are suggested with both of 4 kV/m and 10 kV/m for electric field, and 100 μT for magnetic field in national standard.
