Abstract
Description
Claims (2)
- 전원용 삼상, 단상과 신호용 회로에 있어서 낙뢰의 전압을 감지하는 아래스타, 바리스타를 직렬, 또는 병렬로 연결하여 작동하는 낙뢰감지기(A10-A25)와낙뢰 방전 전류를 어스로 보내는 접지 단자(G)와 낙뢰 감지기 (A10-A25)가 작동시 접지 방전 전류를 측정하는 영상 변류기(ZCT)와 영상 변류기(ZCT)에서 접지 방전 전류를 측정후 작동하는 제어용IC(C.IC)와 접지 방전 전류를 제어용 IC( C.IC )에서 연산 후 기계적으로 작동 하는 트립 코일(MC1-MC3) 과상기 낙뢰 감지기(A10-A25)에서 접지 방전 전류 신호에 따라 트립코일이 작동하여 전원 L1, L2, L3의 회로를 끊는 주접접 (CB1-CB3)으로 구성된 낙뢰 인식 제어 장치
- 낙뢰입력시 제 8도 플로우 챠트와 같이,초기(0 - 10 ㎲이하)에는 방지기로 작동하며,중기(10㎲ - 3 ㎳이하)에는 방지기 + 감지기로 작동하여 감지기에서 방전하는 접지전류를 영상변류기(ZCT)로 변환 하여 이를 연산 후 이상시 회로의 주 접점을 차단하며, 말기(3ms - 30ms이하)에는 2차회로에 남아있는 고전압을 계속 방전하여 기기측 회로에 안전 전압을 유지 시키는 것을 특징으로 하는 낙뢰 인식 제어 방법.
