Abstract
본 발명은 과전압차단기, PTC레지스터 및 전압제한소자에 의해 과전압 및 과전류로부터 원결통신장치를 보호하기 위한 방법 및, 상기 방법을 수행하기 위한 보호회로에 관한 것이다. 본 발명의 목적은 과전압 및 과전류로부터 통신장치를 보호하기위한 방법 및 회로를 제공하는 것으로서, 과전압차단기(1)의 응답전압이 전원전압의 피크값보다 높고, 사이리스터 다이오드(4,5)의 응답전압이 보호되는 선의 최대동작전압값 보다 약간 높게 선택되며, PTC레지스터(2,3)가 분리소자로 사용되어 전원전압의 최대진폭을 차단함으로써, 서지-전류를 저지 및 역저지하여 선의 보호를 실현할 수 있다.
