Base data establishment of suitability for Toughened Glass Stem Insulator applied in the high speed catenary system

고속전차선로 유리애자 현장 적합성 기반 구축 연구

The Operation of high speed train in year 2004 bring about a great change in railroad industry. Especially in railroad construction field we have acquired great Know-how. And up to now we are building up operation skills. But the high speed train system are totally imported, so it is necessary to investigate some of the equipment based on our own environment. In case of Toughened Glass Stem Insulator, we don't have any application case in domestic and limited in abroad. So there must be some characteristic estimation. This paper introduces estimation methode in three different field. First electrical field, Second physical field and finally environment circumstance. In Electrical field, amplitude and number of time for abnormal peak voltage data are collected. And in physical field case, amplitude and trend of vibration in to the insulator are examined. And I circumstance case, possibility of flying gravel and ice clod are investigated. Through this basic data, suitability for Toughened Glass Stem Insulator using in domestic will be accumulated and estimated.
