中文摘要 | 導體的交流電阻值要比直流電阻高,這種因為集膚效應產生的影響很難做精確的分析,而且需電磁場模擬來定量估算。要準確對一任意形狀的導體做預測幾乎是不可能;然而利用有限元素分析法可以把一複雜困難的二維甚至三維微分或偏微分系統轉換成簡單之代數問題來解。本文應用有限分析法對不同直徑及形狀之銅導線集膚效應做模擬,並分別計算其交直流的電阻比。 一步貼近高科技產業因停電而導致之斷電成本損失。本次調查之高科技產業包括有半導體、電腦周邊、通訊、光電、精密機械及生物科技等六類別。本調查除了顯示出高科技產業之斷電成本外,同時亦嘗試去獲得高科技產業對電力品質要求的初步資訊,在本次調查中的重要發現與結果,本論文亦將其有條理的整理出來。 z產學合作之參考。 為了達到上述之目的,本研究採用系統化的方法來建構整個研究。以系統化所訂定之整體性架構包含三階段:產學合作運作系統之建構、問內調查、結果分析與改進建議。在產學合作運作系統之建構階段:使用文獻探討配合專家會談方法彙整出產學合作的內涵、調查目前技專院院產學合作運作策略及建立目前產學合作有關整體效益評估指標。在問卷調查階段:根據調查所得的運作策略及所建立效益評估指標,來進行調查分析。在結果分析與改進建議階段:分析各個策略對各方面效益影響,藉以評估檢討運作策略並研議變進辦理產學合作的策略。 |
英文摘要 | The AC resistance of a conductor is known to increase noticeably above its DC value. This phenomenon, which dominates resistance increase due to skin effect, is difficult to analyze precisely and has generally required electromagnetic simulation for quantitative assessment. The accurate prediction of the physical behavior of an arbitrary shape model is almost impossible. The finite element analysis is one whereby the difficulty of mathematically solving large complex geometric problems is transformed form a differential equation approach to an algebraic problem, in which the finite elements have all the complex equations solved for their simple shapes. The application of finite element analysis to a circular copper wire shows the skin effect on different diameters, and the AC/DC resistance rations also are calculated in this paper. r the power company to select the dustribution transformers at the early planning stage. k-pulse (IBP) functions in literature. |
