Abstract
Description
Claims (1)
- 선로의 임의의 지점에서 선로 이상 발생할시 방향성 릴레이가 동작하여 선로 상태신호를 발생하는 계전기 세트(20)와, 선로 이상시 선로를 차단하는 선로차단기(30)와, 광통신 단국장치(50)를 구비하는 고압 송전 자동 절체 장치에 있어서, 자국측 계전기 세트(20)의 동작상태에 따라 정상상태일시 제1제어데이타를 발생하고, 선로 고장상태일시 오버헤드비트 클럭에 동기된 블로킹 데이타인 제2제어데이타를 발생하여 대국 광통신 단국장치(50)로 전송하는 송신부(41)와, 대국 광통신 단국장치(50)에서 발생하는 제1 또는 제2제어데이타를 완충하는 버퍼부(42)와 , 상기 버퍼부(42)에서 제2제어신호 발생시 동작되어 선로의 에러를 보상하며 소정제어 신호를 발생하는 선로 에러 보상부(43)와, 내부 릴레이를 구동시켜 자국 변전소의 선로 차단기의 트립을 방지하도록 선로 차단기 제어회로(30)를 동작시키는 릴레이구동부(44)로 구성됨을 특징으로 하는 고압송전 자동절체장치.
