瞬态脉冲干扰及其抑制方法浅析

Brief Analysis of Transient Pulse Interference and the Suppressing Method

在各种水电自动化系统中,各种控制继电器和继电保护器往往都工作在比较恶劣的电磁环境中,经常会受到各种电磁信号的干扰,严重影响系统的正常工作。在这些干扰信号中,影响较大的是瞬态脉冲干扰。文章从分析瞬态脉冲干扰产生的原因着手,简要总结了各种瞬态脉冲干扰的特征,提出了一些瞬态脉冲干扰抑制的方法。

In various automatic water-power-supply systems, the pilot relay and relay protector work without exception in a rugged electromagnetic environment and are frequently interfered by electromagnetic signals, especially the transient pulse interference, which will bring tremendous harm to the normal work of the system. From the occurring reasons of it, the paper summarizes the features of transient pulse interference and works out some suppressing methods.
