碩士 === 國立臺北科技大學 === 電機工程系研究所 === 97 === 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.
