本文旨在揭示在集电弓与接触导线滑动接触时对电磁发射所进行的测量结果。为此我们安排了不同的试验配置,还特别在屏蔽的室内安装一小段接触网和实际应用尺寸的集电弓,以求获得决定辐射发射特性的主要参数,以便更好地了解因电弧引起的辐射场的机理。试验所取得的结果证明电弧对于整个线路的电磁发射而言实际上是微不足道的。
The purpose of this article is to reveal the results of measurements of electromagnetic emissions when the pantograph is in sliding contact with the contact wire. To this end, we have arranged different experimental configurations. In particular, we have installed a small section of catenary and actual size pantographs in a shielded room in order to obtain the main parameters that determine the radiative emission characteristics in order to better understand the arc-induced Radiation field mechanism. The results obtained from the tests demonstrate that the arc is practically negligible for the electromagnetic transmission of the entire line.
