摘要

近年由於市容美觀及供電安全等因素，電力公司之輸、配電系統逐漸朝地下化設計，尤其輸電系統地下化日漸增多，69kV~345kV之架空輸電線經由電纜連接站轉入地下電纜後進入市區或重要負載區，因此電纜接續技術成為供電可靠度重要研究課題。
本論文以161kV XLPE地下電纜為研究對象，首先整理高壓電纜基本結構及內部電應力分佈，其次探討電纜端末接續技術及其對電應力局部集中改善效果；最後利用有限元素方法軟體(COMSOL)建立電纜端末組件模型，模擬電纜端末接續之電場強度。

For safety and pleasant city out looking reasons, the underground-type transmission/distribution system was widely adopted by TPC in recent years. Especially more and more 69kV~345kV level electricity power by HV underground power cables are supplied to city center through connection stations. The connection technique becomes an important topic of power system reliability.
This thesis focuses on the 161 XLPE underground power cables. Firstly, the structure of power cable and electric stress are studied. Then the connection method for terminations of power cables is introduced. Finally, the COMSOL package is used to simulate the electric stress of termination of power cables.
