The research shows that the protection of the industrial control system are not only need the external lightning protection system such as air terminals , down conductors and grounding system , but also need the internal lightning protection system such as equipotential bonding , shielding and surge protection of information system and electrical system 經研究,對工業控制系統的防雷保護不僅要做好接閃器,引下線,接地體等基本的外部防護,還要做好等電位聯結,屏蔽,信號系統和電源系統的電涌保護等相關內部防雷措施。

Verification of extraneous conductive parts in response to trade enquiries , we take this opportunity to explain one of the determination methods for extraneous conductive parts and their bonding requirements as specified in the code of practice for the electricity ( wiring ) regulations ( cop ) . the provision of equipotential bonding can effectively reduce the risk of electric shock arising from faulty electrical installations 本署收到多宗業界關于確定非電氣裝置金屬部分及其等電位接駁的查詢,我們希望藉著今次通訊,向大家講解測定非電氣裝置金屬部分的一種方法及其在《電力(線路)規例工作守則》 (下稱工作守則)中的等電位接駁要求。

The main work can be summed up as follows : firstly , we studied the thermal - field properties of vcsels , and analyzed the influences of current spreading , material parameters and operating conditions on the temperature distributions . secondly , we began with the electrode voltage and calculated the equipotential s distributions , compared the distributions of voltages and current densities in different depths of vcsels , and then studied the influences of the oxide - confining region with different position or thickness , and the different sizes of the gain - guided aperture and emitting window on the distributions of the injected current density , carrier concentration and temperature in the active region . thirdly , we realized the coupling of electricity , optical and thermal - fields , worked out the threshold voltage , calculated the distributions of the injected current density , carrier concentration and temperature under different offset voltages , and analyzed the impacts of temperature profile and carrier density on the refractive index , fermi levels and optical - field 具體工作可以概括如下:首先,研究了vcsel的熱場特性,分析了電流擴展,材料參數和工作條件對于溫度分布的影響;其次,從電極電壓入手,計算出激光器中的等勢線分布,并對不同深度處的電壓和電流分布進行比較,研究了高阻區的不同位置和不同厚度、限制層和出射窗口半徑的大小對電流密度、載流子濃度和溫度分布的影響;再次,實現了電、光、熱耦合,求出了閾值電壓,計算了不同偏置電壓下的電流密度分布、載流子濃度分布和熱場分布,分析了溫度和載流子濃度變化對折射率、費米能級和光場的影響;最后,給出了考慮n - dbr和雙氧化限制層時激光器中的等勢線分布,分析了n - dbr和雙氧化限制層對vcsel電流密度、載流子濃度、溫度和光場分布的影響。

With numerical calculations , the influences of device structure , material parameters and operating conditions on the distributions of the equipotential line , current density , carrier concentration , optical field and temperature profiles have been investigated , and the interactions between the correlative characteristics have been studied at the same time 通過對這些相互關聯的特性進行數值計算,分析了器件結構、材料參數和工作條件等對等勢線分布、注入有源區的電流密度、有源區中的載流子濃度、光場強度以及溫度分布的影響,并研究了這些特性之間的相互影響。

Typical examples are water mains and gas pipes . equipotential bonding consists of main and supplementary equipotential bondings . it means the electrical connection linking various exposed conductive parts and extraneous conductive parts so as to achieve a substantially equal potential 至于等電位導體的作用,其實就是將各個外露非帶電金屬部分和非電氣裝置金屬部分作電氣性連接,使各部分的電位在頗大程度上相等。
