Abstract

In this paper we study the performance test items and improvement plans of surge protective devices for low-voltage power circuits used in railway system. Above of all, the sources of electromagnetic interference in railway system are researched. And then we compared domestic railway standard with IEC and IEEE standards far the test items and methodologies of surge protective devices. Through the investigations, we found that the domestic standard is behind in the number of test items and methods on surge protective devices. As the countermeasures, we suggest removing component tests of surge protective devices, separating standards for power and signal standards, and using international surge waveform. In applying to domestic railway surge protective devices, surge limiting voltage measuring and surge endurance tests by international standard methods are good result.

본 논문에서는 철도 시스템에서 사용하는 저압 전원용 서지보호장치(surge protective devices) 규칙의 성능평가 항목 및 성능개선 방안에 대하여 고찰하였다. 먼저 철도시스템 환경과 관련된 전자기장해(electromagnetic interference) 현상을 검토하였다. 그리고 국제규격인 IEC 및 IEEE와 평가항목 및 펑가방법 등을 비교 검토하였다. 검토 결과 국내 철도관련 규격은 국제규격과 비교하여 비교하여 발견하였다. 개선방안으로 서지 보호소자 단위의 시험은 삭제하고, 규격 종류는 전원용과 신호용으로 분리하며, 서지 파형은 국제적으로 인정된 것을 사용하도록 제안하였다. 철도용 저압 서지보호장치에 대해 서지제한전압 측정 및 서지 수명시험을 국제규격에 따라 시험한 결과 만족스러운 결과를 얻었다.
