摘要

强中频发射机的电磁场在充当非故意接收天线的大型导电结构中产生电流。这些结构包括建筑起重机、塔式起重机、门港起重机和重装桥，因此工人可以感受到接触电压和短路电流。本文将起重机作为线天线结构，在一定频率和传播方向的平面波电磁场中，用点匹配法求解电流分布近似为多项式的哈伦型电场积分-微分方程组。本文给出了这一问题的可能解决方法。

Induced currents in cranes in electromagnetic field of MF transmitters

Electromagnetic field of powerful MF transmitters induces currents in large-scale conductive structures which act as unintentional receiving antennas. Among such structures are construction cranes, tower cranes, portal-harbour cranes and reloading bridges, so that touch voltages and short-cut currents are experienced by their workers. Calculations are presented in this paper for cranes treated as wire antenna structures in plane-wave electromagnetic field of some frequency and propagation direction, using Point matching method for solving the system of electric field integro-differential equations (EFIE) of Hallen's type with current distributions approximated by polynomials. Possible solutions of this problem are given in the paper.
