基于电场理论的主动防雷系统的初步设想

针对目前使用的传统雷电防护技术存在的问题，通过分析雷电原理和雷电触发机制，利用电场理论来设计一套主动防雷系统，即实现保护对象所在空间大气处于被激放电状态，并利用闪电将大气激活为自激放电状态。介绍了主动防雷系统的原理，并对其核心的“引而不发”理论进行阐述，在此基础上设计出主动防雷系统的模型。具体说明了构成主动防雷系统的阻塞系统、疏导系统和电源系统的构造和特征以及它们之间的关系。计算得到主动防雷系统所需的电场强度E=0．69kV／m。最后指出了存在问题与发展方向，在结论中总结了主动防雷系统的特点及其关键。

An Inititive Lightning Protection System Based on Electric Field Theory

Aiming at the problems of the traditional lightning protection technology,through analyzing lightning theory and triggering mechanism,and by utilizing electric field theory,this paper designs a set of initiative lightning protection system(ILPS),which makes the atmosphere around protected objects being in a passive-excitation discharge state and employs lightning current to induce the atmosphere into a self-excitation discharge state.The paper introduces the theory of ILPS,also elaborates the kernel theory of leading and retaining,then with this understanding puts forward the model of ILPS.And the paper illuminates in detail the structures,features and the relationship of pushing system,leading system and power system in ILPS.The calculated electric field intensity required for ILPS is E=0.69kV/m.Finally its problems and developing directions are also given,and the characteristics and key of ILPS are summarized in the conclusion.
