鐵路電車線系統整備測試方法研討

鐵路電車線系統整備測試為鐵路電車線系統於新建完成或改建完工後，加入營運前，所施行之各項測試，大致分為電車線加壓送電、短路測試及干擾測試。本論文之研究重點，即為檢視以往鐵路電車線系統所採用之干擾測試執行程序及方法，是否符合台灣鐵路現階段需求。電車線系統加壓送電及短路測試分別為，簡易及制式化測試程序。有別於干擾測試係利用發電機以低電壓、低電流，來模擬鐵路電車線運轉時的電流與磁場分佈狀態，透過相關儀器測量各式數據，檢視各設備是否符合鐵路相關規範。有鑑於測試用的儀器設備日益輕巧精良，如何應用新式設備來提高測試效率及精確度，亦為值得思考的議題。電車線系統整備測試，經由儀器的測試數據提供判讀，可檢測出整個系統的缺失並立即改善，以達到保障鐵路沿線設備與人員的安全。測量方式猶如身體檢查，可以分為許多等級及種類，有簡單的、複雜的、快速的、精密的、昂貴的或經濟的。故重新檢視目前所沿用之國外電車線系統測試方法，並研究探討其它可行性，配合測試條件及需求，選擇最佳之測量方法即為本論文之研究重點。

Railway overhead contact system commission test includes pressured-electricity delivery test, interference test and short circuit interference test is implemented before the operation of the newly-built construction or reconstruction. The key of this paper is to survey if the commission test procedures and methods of interference test that have been used on railway overhead contact system in the past can meet with the requirements of Taiwan railway at modern age. Railway overhead contact system commission test included Interference test and short circuit of Interference test. Under these two tests, it also can be separate to two different methods simple and uniform. In the past, the generator had been used in the interference test to supply low voltage and electric current to simulate the condition about electric current and magnetic-field distribution in the operation of railway overhead contact system; exam if the figures will conform to railway specification by the readings of test instrument. How to improve the efficiency and accuracy of the tests by up-to-day modern test instruments would be also a considerable topic for discussion. Through the construction commission test, the test instruments can direct us to find and correct the potential defects and problems timely to ensure the safety of railway assets and working staffs. Since test methods are various, how to find the best test method to match up real conditions and demand of Taiwan railway is the main subject of this research.
