Abstract

Abstract The paper presents issues associated with the impact of electromagnetic interference on static converters, which exploitation in a railway transport environment. The measurements of an electromagnetic field emitted by a static converter were shown. Designs of this kind are exploitation in railway facilities, therefore, they should not disturb the functioning of other equipment, the rail traffic control systems, in particular. As a result of the EMC tests, it was concluded that the permissible values of conducted interference emissions were exceeded. An analysis of the obtained results enabled developing a research model, and a further reliability and exploitation analysis, taking into account electromagnetic interference. This, in turn, enabled determining a relationship allowing to determine the probability of a static converter staying in a state of full ability. The presented discussions regarding a static converter, taking into account electromagnetic interference, allow for the numerical assessment of different types of solutions (technical and organizational), which can be implemented in order to mitigate the impact of electromagnetic interference on a system’s functioning.

考虑电磁干扰的静态变换器可靠性开发分析

摘要本文介绍了在铁路运输环境中开发的静态变流器的电磁干扰影响问题。给出了静态变换器电磁场的测量结果。这种设计是在铁路设施中进行的，因此，它们不应该干扰其他设备，特别是轨道交通控制系统的功能。根据电磁兼容测试，得出的结论是，传导干扰发射的允许值已超过。对获得的结果进行分析，可以开发研究模型，并进一步进行考虑电磁干扰的可靠性和开发分析。这反过来又使确定关系成为可能，从而确定静态转换器保持满能状态的概率。所提出的关于静态转换器的讨论，考虑到电磁干扰，允许对不同类型的解决方案(技术和组织)进行数值评估，这些解决方案可以实施，以减轻电磁干扰对系统功能的影响。
