電纜線銅導體套管的魯棒設計

Robust Design of Sleeves for Copper Conductor of Cable

指導教授 : 洪穎怡

摘要


近年來隨著台灣環境的影響,地下電纜的比例越來越高,在未來的研究以及討論上應該都會朝減少成本來進行,當然在安全性及穩定性上也須要兼顧。本文主要探討電纜銅導體的接續套管的溫度及成本。 本文是使用田口法的實驗組合來進行模擬,首先是先找出哪些是控制因子,再找出每個因子的水準,建立出一個田口的實驗組合,再設置合理的輸出以及干擾進行模擬,模擬結果就是銅套管的溫度,再計算S/N比因子反應以及品質特性的因子反應,來分析最佳解,再來計算田口法實驗組合的體積以及重量,根據國際的基本金屬價格來判斷價格,進行計算各後,把原始製成以及最佳解的製程進行比較,來驗證最佳解是否有比原始解來的便宜。

In recent years, the share of underground cables has increased due to the influence of Taiwan’s environment. Future research and discussion should focus on the reduction of cost and enhancement of safety and security for these underground cables. This thesis mainly focuses on temperature and cost of the copper sleeves for copper conductors that are mainly used in cabling. This thesis uses the Taguchi's method to simulate a factorial design of experiments. First is to identify the control factors. Then the level of each factor is determined. Selection of the orthogonal array is then established. Finally, output-to-noise ratio analysis is performed. The result is determined by analyzing the factor response of copper case temperature, S / N ratio, and quality characteristics to get the optimal solution. The volume and the weight of the experimental combination of the Taguchi's method are calculated, and the price is judged according to the international basic metal price. After performing the calculations, the original fabrication and the optimal solution are compared to verify that the optimal solution is cheaper.
