Claims (2)
- 철도의 전원선로(30)에 설치되는 낙뢰보호장치에 있어서,
상기 낙뢰보호장치(100)는 전원선로(30)와 연결되어 낙뢰로 인한 이상전압이 발생되면 순간적으로 부도체로 변하여 전원선로(30)를 차단하고 반대로 정상전압이 공급되면 도체로 변하여 정상전압을 제어실(20)로 공급시키기 위한 SSR소자(110)와; 상기 전원선로(30)와 연결되어 평소에는 상기 SSR소자(110)를 통과하는 정상전압을 제어실(20)로 공급하고 반대로 SSR소자(110)가 소손되어 이상전압이 전달되면 지면으로 접지시키기 위한 바리스터(120)로 구성되되, 상기 SSR소자(110)는 전원선로(30)를 통해서 전달되는 AC전압을 DC전압으로 정류시키기 위한 다이오드(111)와; 상기 다이오드(111)를 통과하는 AC전압의 싸인파를 평활시키기 위한 콘덴서(112)와; SSR소자(110)를 도체 또는 부도체로 변환시키기 위한 기준전압을 설정하는 저항(113)이 포함되는 것을 특징으로 하는 철도용 낙뢰보호장치. - 삭제
