中文拼音 [léidiànfǎnjī]
雷電反擊
英文
back flashover-
Glinka, who was recognised and greeted with shouts of the author, the author ! said that hell must be driven back by hell, that he had seen a child smiling at the lightning flash and the thunder clap, but we would not be like that child
人群中傳出喊聲,這位出版家說,地獄應當用地獄來反擊,他曾見過一個孩子在雷電交加的時候還在微笑,但是我們不要做那個孩子。Obtained by emtp program and the egm, this paper studies on lightning protection performance on 500kv double circuit transmission line the distributed parameter model of tower is built when analyzing the back stroking lightning protection performance for double circuit line, it can truly reflect the spreading course of lightning current on the tower, furthermore, considering the randomness of working voltage ' s phase when lightning strokes the top tower and supposing the probability of lightning appearing arbitrary phase in a cycle of ac is equal, this paper brings forward the statistical method to calculate the rate of back stroking on double circuit line
本文利用emtp程序、擊距法對500kv同桿雙回線路的耐雷性能進行了研究。在分析同桿雙回線路的反擊耐雷性能時,建立了桿塔的分佈參數計算模型,此模型可以真實地反映雷電流在桿塔上的傳播過程。並針對雷擊塔頂時,導線運行電壓相位角的隨機性,本文假定雷擊出現于交流一周期的任一角度區間內的概率相等,提出了利用統計法計算同桿雙回線路的反擊跳閘率。In this dissertation, first, the basic conceptions of ew, radar ew and combat effectiveness are made clear about internal characteristics, consist and tasks. then, the evaluation factors architecture of radar ew system combat effectiveness is set up, which is the base of quantificational evaluation. second, mathematics modeling of radar ew reconnaissance, radar jamming and anti radiation attack are constructed
本論文的研究首先從電子戰、雷達對抗、武器裝備作戰效能的基本概念出發,理清其內涵、特點、組成、任務,從而建立以能力為主線的雷達對抗系統作戰效能評估指標體系,為定量評估系統作戰效能奠定基礎;然後分雷達偵察、雷達干擾、反輻射攻擊分別對雷達對抗系統武器裝備的電子偵察能力、電子干擾能力、電子進攻能力進行數學建模,進而建立系統綜合對抗能力數學模型,為系統模擬建立設計基礎。
