城市地铁乘客区磁场环境人员适应性分析
Analysis on Adaptability of Magnetic Fields in Passenger Area of
City Subways to Personnel
摘要 列车乘客区电磁环境可能引起乘客的不适反应,或对随身佩戴的助听器、心脏起搏器等电子产品造成干扰。通过对牵引系统中的电流特性分析,得出列车乘客区的电磁场主要为静磁场及极低频磁场。利用CST 软件对DC110 V 线缆等分别进行静磁场或工频磁场仿真,并进行车上磁场水平实测。通过对比ICNIRP 导则和IEEE 标准限值,得出列车乘客区磁场环境具有良好的人员适应性。

Abstract The electromagnetic environment in subway passenger area may make
passengers feel uncomfortable, or cause interference on the hearing aids, heart
pacemakers and other electronic products. It is found that static and extremely low
-frequency magnetic field were the main composition of the electromagnetic fields in
subway's passenger area by analyzing the current characteristics of the traction system
The static magnetic fields or alternating magnetic fields of the DC100 V and other
several cables were simulated by CST software, and the magnetic field level in actual
carriage of the subway were measured. According to ICNIRP guidelines and limit
values in IEEE standard, the magnetic field environment in passengers area is
acceptable for personnel.
