Is properly controlled, and the output from the terminal is controlled through the resistor R 19 (R 20 ) (R 21 ). The current is supplied from the silicon rectifying element which is applied to the gates of SCR 1 to SCR3 and is forward biased first of the silicon rectifying elements SCR 1 (SCR 2 ) and SCR 3 .

이때 다이오드(D4)(D5)(D6)의 정류전압은 릴레이(6)를 거쳐 저항(R12)에서 일단 전압강하되고, 전압강하된 정류전압은 저항(R5)을 통해 단일접합 트랜지스터(Q2)의 베이스(B2)와 저항(R10)을 통해 단일접합트랜지스터(Q4)의 베이스(B2m) 에 전압이 공급되며, 한편 가변저항(R11) 을 통한 전압은 제너다이오드(D8)에 의해 일정전압으로 유지된다.The diode (D4) (D 5), (D 6) of the rectified voltage is single-junction transistor through the relay 6, the through resistance (R 12) once the voltage drop is, voltage drop across the rectified voltage resistance (R 5) in the Voltage is supplied to the base B 2m of the single junction transistor Q 4 through the base B 2 of Q 2 and the resistor R 10 , while the voltage through the variable resistor R 11 is applied to the zener diode. It is maintained at a constant voltage by (D 8 ).

단일접합트랜지스터(Q2)의 에미터(emitter)에 가변저항(R7) 및 저항(R6)의 직렬저항값과 컨덴서(C3)의 충·방전 전압을 인가하여 단일접합트랜지스터(Q2)의 벨리볼테지(Valley Voltage)부저항특성으로 인하여 저항(R4)의 양단에 제어펄스가 발생하는데 이는 실리컨 정류소자의 게이트펄스(gatr pulse)로 사용하여 다이오드(D4)(D5)(D6)의 충정류전압에 보호저항(R3)을 통하여 실리컨정류소자(SCR4)를 통전시켜 실리컨정류소자(SCR4)의 캐소드(catrhode)에 병렬연결된 컨덴서(C1)와 저항(R1)의 양단에 증폭된 게이트펄스를 단자(⑩)을 통해 실리컨 정류소자(SCR4)의 게이트에 각각 인가하므로써 3개의 실리컨 정류소자(SCR1)(SCR2)(SCR3)중 어느 것 하나가 제일 먼저 통전하여 정류전압이 플러스단자(⑦)에 직렬연결 된 쵸크코일(2)를 통하여 밧데리에 보다 적은 리플전압(ripple voltage)을 공급함으로 밧데리에 거의 직류와 같은 전압을 인가하여 밧데리의 수명연장 및 충분한 충전을 할 수 있게 된다.Variable resistor to the emitter (emitter) of the single-junction transistor (Q 2) (R 7) and a resistor (R 6) one by applying a charge-discharge voltage of the series resistance value and a capacitor (C 3) junction of the transistor (Q 2 Control voltage is generated at both ends of resistor (R 4 ) due to the voltage resistance of the valley voltage of the diode, which is used as a gate pulse of the silicon rectifier element (D 4 ) (D 5 ) The capacitor C 1 connected in parallel to the cathode of the silicon rectifying element SCR 4 by energizing the silicon rectifying element SCR 4 through the protection resistor R 3 to the charge rectifying voltage of (D 6 ).

본 고안의 제2도의 예시도면에 의해 제어회로부를 보다 상세히 설명하면 다음과 같다.Referring to the control circuit portion in more detail by way of example 2 of the present invention as follows.

가변저항(R9)은 3상 입력전압(R, S, T상)의 변동을 보상하는 소자이고, 가변저항(R11)의 양단전압중 저항(R5)(R10)에 연결된 전압은 변동된 상태 그대로 유지되나 가변저항(R7)(R9)에 연결된 전압은 제너 다이오드(D8)에 의하여 일정전압을 유지함으로 입력전압의 변동분을 보상하여 주고 있으며 가변저항(R7)은 제너다이오드(D8) 일정전압을 유지하고 있으므로 가변저항(R7)값의 변화에 따라 컨덴서(C3)와 가변저항(R7)의 충·방전시간을 조절하여 실리컨 정류소자의 통전각(0-180)에 따라 단자(⑩)에서 정류기 제어회로(1)의 출력전압을 얻을 수 있다. 이때 가변저항(R9)을 조정함에 따라 입력전압(R, S, T 상)의 상불평형을 감지하여 가변저항(R7)과 저항(R6)을 통하여 단일접합 트랜지스터(Q2)의 에미터에 가해지는 제어펄스 전압이 가변저항(R9) 및 저항(R8)과 컨덴서(C4)의 충·방전 전압으로 단일접합 트랜지스터(Q4)의 에미터에 가해저 저항(R5)을 통하여 단일접합트랜지스터(Q2)의 베이스(B2)에 가해지던 전압이 저항(R10)을 통해 단일접합트랜지스터(Q4)의 베이스(B2m)에서 베이스(B1)쪽으로 기울어지면 단일접합트랜지스터(Q2)의 발진이 정지되어 실리컨 정류소자의 케이트 신호를 차단하게 되므로 정류상태를 정지시킨다. 또한 트랜지스터(Q3)의 에미터에는 저항(R13)과 가변저항(R14) 및 저항(R15)의 분압비에 따라 제너 다이오드(D9)를 통해 일정전압이 인가되는데 제너다이오드(D9)의 정전압을 초과할때 트랜지스터(Q3)가 통전되어 단일접합 트랜지스터(Q2)의 발진이 정지되므로 정류상태가 정지된다.The variable resistor (R 9 ) is a device for compensating for the variation of the three-phase input voltage (R, S, T phase), the voltage connected to the resistor (R 5 ) (R 10 ) of the voltage across the variable resistor (R 11 ) The voltage is maintained in the changed state, but the voltage connected to the variable resistor R 7 (R 9 ) maintains a constant voltage by the zener diode D 8 to compensate for the change in the input voltage, and the variable resistor R 7 is zener. a diode (D 8), so maintain a certain voltage-dependent resistor (R 7) a capacitor in accordance with the change of the value (C 3) and a variable resistor (R 7) barrel's silico-conditioner stop by controlling the charge and discharge time of the full-width (0 The output voltage of the rectifier control circuit 1 can be obtained at the terminal according to -180. The variable resistor (R 9), a variable resistor by detecting the unbalance of the input voltage (R, S, T phase) as the adjusting (R 7) and a resistance (R 6), the emitter of the single-junction transistor (Q 2) through the the control pulse voltage applied to the emitter is applied to the emitter of the variable resistor (R 9) and a resistor (R 8) and a capacitor (C 4) single-junction transistor (Q 4) as a charge-discharge voltage of the low-resistance (R 5) When the voltage applied to the base B 2 of the single junction transistor Q 2 through is inclined from the base B 2m of the single junction transistor Q 4 to the base B 1 through the resistor R 10 , Since the oscillation of the junction transistor Q 2 is stopped to cut off the gate signal of the silicon rectifier element, the rectified state is stopped. In addition, a constant voltage is applied to the emitter of the transistor Q 3 through the zener diode D 9 according to the voltage divider ratio of the resistor R 13 , the variable resistor R 14 , and the resistor R 15 . When the constant voltage of 9 ) is exceeded, the transistor Q 3 is energized to stop oscillation of the single junction transistor Q 2 , and thus the rectified state is stopped.

본 고안의 저항(R13), 가변저항(R14), 저항(R15) 및 제너다이오드(D9)로 구성되어진 정전압회로(12)는 충전전압을 일정하게 유지시키기 위한 회로이며, 밧데리에 충전하기 전에 미리 가변저항(R14)을 일정한 값이 되도록 정해야 한다.The constant voltage circuit 12 composed of the resistor R 13 , the variable resistor R 14 , the resistor R 15 , and the zener diode D 9 of the present invention is a circuit for maintaining a constant charging voltage. Before charging, the variable resistor R 14 should be set to a constant value in advance.

변류기(eurrent transformer)(4)는 입력전압(R, S, T상)의 R상 또는 T상의 선로상에 관통형으로 부착해서 선로에 흐르는 전류를 감지하여 정류기 제어회로(1)의 단자(⑪)(⑫)를 통해 브릿지 정류회로(5)로 인가되고 브릿지 정류회로(5)에서 정류된 전압은 저항(R16)(R17)(R18)과 가변저항(R22), 그리고 콘덴서(C5)로 구성된 회로에서 리플이 제거되어 다이오드(D10)를 거쳐 실리컨 정류소자(SCR5)의 게이트에 인가되어 실리컨 정류소자(SCR5)를 동작시키면 실리컨 정류소자(SCR5)의 출력전압으로 진공 릴레이(6)는 개방상태(b)에서 폐쇄상태(a)로 되어 정류기 제어회로(1)는 동작을 하지 않게 되고 표시등(8)이 점등되어 과전류된 상태를 알려주게 된다.A current transformer 4 is attached to the R phase or the T phase line of the input voltages R, S, and T phases in a penetrating manner so as to sense current flowing through the line, and thus the terminal of the rectifier control circuit 1 Is applied to the bridge rectifier circuit 5 and rectified in the bridge rectifier circuit 5 by the resistors R 16 , R 17 , R 18 , the variable resistor R 22 , and the capacitor ( C 5) is ripple is removed from the configured circuit of a diode (D 10) a via is applied to the gate of the silica container rectifier (SCR 5) when operating a silica container rectifier (SCR 5) silica container rectifier (SCR 5) With the output voltage of, the vacuum relay 6 becomes the closed state (a) from the open state (b) so that the rectifier control circuit 1 does not operate and the indicator 8 lights up to inform the overcurrent state. .

스위치(7)는 이를 오프(off)시키면 과전류된 상태에서 폐쇄 상태(a)에 있던 진공 릴레이(6)를 다시 개방상태(b)로 전환되게 하여 정류기 제어회로(1)를 정상 동작하게 하는 리셋 스위치(reset switch)(7)이다.The switch 7 resets the vacuum relay 6 in the closed state (a) to the open state (b) by turning it off so that the rectifier control circuit 1 operates normally. Reset switch (7).

상기한 바와 같이 본 고안은 갱내에서도 불꽂발생의 위험이 없는 상태에서 안전하게 축전지를 충전시킬 수 있는 효과가 있다.As described above, the present invention has the effect of safely charging the battery in a state in which there is no danger of fire occurrence in the gang.
