Claims (3)
- 활선 경보 장치에 있어서,스위치(SW1)를 단락시켜 밧데리의 전원을 회로에 공급하고,검지전극(INPUT)이 활선에 흐르는 전압에 대전되어 전극(INPUT)과 어스(GND) 사이에 상이한 전압이 유도되고,유도된 전압은 상기 트랜지스터(Q1) 및 이 트랜지스터(Q1)과 결합된 트랜지스터(Q2)에 의하여 전압 증폭되고,전압 증폭된 신호가 트랜지스터(Q3)가 스위칭되어 트랜지스터(Q4)를 바이어싱하고, 바이어싱된 트랜지스터(Q4)에 의하여 트랜지스터(Q4)의 에미터에 걸려있던 밧데리 전압의 직류 신호가 전류 증폭되고,전류 증폭된 신호에 의하여 발진용 집적회로(IC1)(IC2)가 발진되어 상기 발진용 집적회로(IC1)의 출력단과 연결된 발광 다이오드(D2)가 발광하고,상기 발진용 집적회로(IC1)의 출력단의 신호를 공통 입력으로 하는 발진용 집적회로(IC3)의 출력단과 연결된 발광 다이오드(D3)가 발광하고,상기 발진용 집적회로(IC3)의 출력단의 신호를 공통 입력으로 하는 발진용 집적회로(IC4)의 출력이 트랜지스터(Q5)의 베이스를 트리거하여 입력 신호를 전류 증폭하여 부저(BZ)를 울리는 구성을 특징으로 하는 활선 경보 장치.
- 제 1 항에 있어서,상기 트랜지스터(Q3)의 콜렉터와 어스(GND) 단자 사이에 테스트단자(TEST)를 연결하고 상기 테스트 단자(TEST)에 푸쉬 스위치 등의 스위치를 연결하여, 스위치을 단락시켜 트랜지스터(Q4)를 강제로 바이어싱하여 경보 장치의 정상작동 여부를 시험하는 것을 특징으로 하는 활선 경보 장치.
- 제 1 항에 있어서,상기 부저(BZ)와 밧데리 사이에 스위치(SW2)를 연결하여, 스위치(SW2)를 개방하면 부저(BZ)가 울리지 않게 하는 구성을 특징으로 하는 활선 경보 장치.
