摘 要
雷電流參數(shù)的測量是進(jìn)行雷電研究的基礎(chǔ)工作，對于研究雷電特性、分析雷害事故、鑒定雷擊跳閘事故責(zé)任、探討防雷對策及為絕緣配合設(shè)計提供精確的大氣過電壓原始數(shù)據(jù)均具有十分重要的意義。相對于現(xiàn)有的測量方法而言用電子電路測量雷電流參數(shù)具有材料便宜、測試精度高、測量信息豐富，適于大范圍雷電普查使用的特點。本論文對雷電參數(shù)測量的機(jī)理進(jìn)行了較為深入的探討，著重于開拓電子電路測量雷電參數(shù)應(yīng)用領(lǐng)域方面的研究，使電子電路既能測量雷電流峰值，又能測量雷電流波頭時間，波尾時間等數(shù)據(jù)。
論文主要分為三個部分。第一部分論述雷電流的產(chǎn)生，參數(shù)，特征及一些測量方面的知識。第二部分簡要介紹高壓實驗，第三部分利用Electronics Workbench作為仿真工具進(jìn)行設(shè)計的電路的模擬。根據(jù)Electronics Workbench得出的數(shù)據(jù)分析用電子電路測量雷電流參數(shù)的可行性。本文研究預(yù)示電子電路在經(jīng)濟(jì)性、實用性、精確性上遠(yuǎn)遠(yuǎn)優(yōu)于現(xiàn)有的其它雷電測量方法。

Abstract
Measuring of lightning parameters is the base work of lightning research. It is very important for researching the lightning characteristics, analyzing the accident of lightning, identifying the responsibility of lightning strike outage accident and discussing of lightning protection .It also can provide precise original data of atmosphere over –voltage for designing insulation co-ordination. Compared with the traditional methods, the proposed ideal has the following advantages such as material cheapness, highly precise and it can support the lighting census in large regions. This paper deeply discussed the mechanism of electronic circuit, mainly focused on the electronic circuit appliance in measuring lighting current parameters, making it not only measure the peak of the lightning current but also its front, trail et al.
My paper is mainly made up of the following parts. The first part introduces the lightning current about its generation, parameters, character and some measuring methods. The second part mainly describes high voltage experiment. And the end part explain applying simulating the lighting current use the soft of Electronic Workbench, and analyze the conclusion to judge the feasibility of this measuring method.
This study in this paper show that the propose method is superior to the present method for the lightning current measuring in the economical, practicability and precision of measurement.
