Hygienic Assessment of ELF Electromagnetic Fields under Electronic Tractive High--voltage Line in Railway Long-tunnel

Pan Lundian;Ruan Zhigang;Yu Zengshun Research Institute of Industrial Hygiene of Railway Ministry 100038  
This is a survey on the disturbance and regulation of electiomagnetic fields under a 27.5kV, 50H~zelectronic tractive line in Railway long- tunnel in China. The average.levels of elactric field strcegth,of the magnetic flux density and of human induced current are 2.01±1.01kv/m. 0.21 ±0.23mT and17.18±9.51μA respectively. The highest strength of above-mentioned three indaxes is under contactsystem and between two steel rails. The lowest is in sidewalk and it is greatly lawer than outsidetunnel. Eyery point levels of three indexes are under the national standatd. These provide scientificbasis for formulating protective measures to keep working of long-tunncl.
