石化企业综合防雷技术探讨

DISCUSSION ON SYNTHETICAL LIGHTNING PROTECTION TECHNIQUES FOR PETROCHEMICAL ENTERPRISES

雷电是自然界中强烈的放电现象,是一种严重的自然灾害,目前还无法控制和阻止它的产生。它具有高电压、大电流和瞬时性特点。当建筑物接闪落雷时,雷电放电过程往往出现三种物理现象:静电感应、强电磁场和辐射电磁波,严重干扰无线通迅和各种电子设备的正常工作,造成许多微电子设备损坏,且传统避雷针等防护系统无法有效保护。根据石化企业的特点,结合当今先进的防雷技术与产品,对当前防雷工程中存在的问题提出一些改进意见。

As a strong discharge phenomenon in na- ture,lightning is a serious natural disaster.At pres- ent,people are unable to control and prevent it from happening.Based on the characteristics of petrochem- ical enterprises and in light of today's advanced light- ning protection theories and techniques,this paper proposes some improvement measures for problems currently exist in lightning protection projects.
