Magnetic indicator for lightning currents 閃電電僚性指示器
Magnetic detector for lightning currents 閃電電流磁檢示器
Since lightning current is conducted away through the ground , you should not lie down especially when the ground is wet 閃電擊中物體后,電流會經地面傳開,因此不要躺在地上,潮濕地面尤其危險。
The first is to fix and debug the impulse current generator and fix kinds of channel models of lightning current by which to generate artificial lightning current 論文主要分為三個部分。第一部分論述安裝、維修、調試沖擊電流發生器,制作各種雷電流通道模型。
The model considers peak value of lightning current , tower grounding resistance , tower style , line surge impedance , power frequency voltage and distance between towers 模型中考慮了雷電流幅值、桿塔沖擊接地電阻、桿塔具體形狀、尺寸、桿塔波阻抗、工頻電壓及檔距等因素的影響。
For the drawback of egm theory , in correction with the simulating calculation result of the latest lsm theory , the improved calculating method and way of detour lightning current was discussed 摘要針對egm理論存在的缺陷,結合最新lsm理論仿真計算結果,探討了改進繞擊電流計算方法的途徑。
Keep away from trees or masts which are likely to be struck by lightning . since lightning current is conducted away through the ground , you should not lie down especially when the ground is wet 樹木或桅桿容易被閃電擊中,應盡量遠離。閃電擊中物體后,電流會經地面傳開,因此不要躺在地上,潮濕地面尤其危險。

We calculate the regression curve about length of erased magnetic record and lightning current peak . we analyze the error of recording data and find a new means about direct measurement of the max lightning steepness with magnetic tapes 作出磁帶消磁長度與霄電流峰值的擬合曲線,對測量數據進行誤差分析,找到利用磁帶直接測量靂電流最大陡度的新方潔。
This paper deeply discussed the mechanism of magnetic tape detector , mainly focused on the tape detector appliance in engineering fields , making it not only measure the lightning current peak but also its supreme deepness . my paper is mainly made up of the following parts 本論文對雷電參數測量磁帶法的機理進行了較為深入的探討,著重于開拓磁帶測量雷電參數應用領域方面的研究,使磁帶既能測量雷電流峰值又能測量雷電流最大陡度。
