变电站自动化装置处于低电平的弱电系统,抗电磁干扰能力较差。本文在阐述电磁干扰的来源及传输途径的基础上,以防雷抗电磁干扰为例,对变电站自动化装置受干扰及抗干扰措施进行了分析。
Substation automation devices in low-level weak system, anti-electromagnetic interference ability. Based on the explanation of the source and transmission path of electromagnetic interference, this paper takes lightning protection and electromagnetic interference as an example to analyze the interference and anti-interference measures of substation automation equipment.
