【摘要】 雷电灾害是自然界存在的灾害之一,其在瞬间释放的强大脉冲电流会产生巨大的能量,并会诱发脉冲过电压或过电流,从而导致严重后果。因此电力电子系统需要加强对雷电的防护措施。文中讨论了雷电电击对计算机控制系统产生危害的原因,分析了雷电波侵入控制系统的主要途径,并提出相关的计算机控制系统防雷措施。更多还原

【Abstract】 Lightning is a natural disaster that releases powerful pulse current with a huge mechanical energy and heat,and thus inducing over-voltage or over-current pulse and resulting in serious consequences.Power electronic systems therefore need to strengthen protective measures against lightning.This paper deals with how thunder and lightning wreck damage on the computer control system and the major means by which lightning surge intrudes the control system,and proposes corresponding lightning protection measures.更多还原
