아퍼레이션 앰프리파이어(연상증포기)(operationamplifier)를 비교기로 사용하여 입력단에 저너 다이오우드를 설치하고 저항에 의해 분압된 전압을 비교하여 op 앰프의 출력전압이 최대 로우로 되어 트랜지스터를 온, 오프하여 고정저항과 콘덴서에 의해 충전회로를 구성하고 가변저항기에 의해 시간를 조정할수 있으며 스위칭 다이오우드(switching diode)의 접속에 의해 트립핑후 콘덴서가 초기 상태로 급속히 되돌아가도록 설치되고 각 모우트, 장한시 단한시, 순시 모우드에서 각각 정해진 제너 다이오우드 동작하고 아퍼레이션 앰프리 파이어가 비교하여 동작되도록 하고 콘덴서 C2와 C3에 의해 센서된 전압 VB가 피크(peak)치에서 충전되어 아퍼레이션 앰프리파이어가 정확히 동작되도록하며 가변저항기VR2에 의해 푸트Q5,Q6,Q7,Q8의 트리거 전압이 조정되도록 하여 전체적인 동작특성 곡선이 옮겨지는 것이 가능하도록 된 정지식 과전류 계전기.By using an operation amplifier refiner (operationamplifier) as a comparator, a negative diode is installed at the input stage and the voltage divided by the resistor is compared. The charging circuit can be configured by the fixed resistor and the capacitor, and the time can be adjusted by the variable resistor, and the capacitor is installed to return to the initial state rapidly after tripping by the connection of the switching diode. The zener diodes are set in instantaneous mode and the amplification amplifiers are operated in comparison. The voltage V B sensed by the capacitors C 2 and C 3 is charged at the peak value, so the amplification amplifier is operated correctly. so that the foot and by the variable resistor VR 2 Q 5, a trigger voltage of Q 6, Q 7, Q 8 the crude Such that by the positive knowledge over current relay to be able to be transferred to the overall operation characteristic curves. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
