본 고안은 정전시 경보회로에 관한 것이다.The present invention relates to an alarm circuit in case of power failure.
일반적인 가전제품인 냉장고나 온장고등은 일정한 고내온도를 항상 유지시켜서 내용물의 상함을 방지하거나, 어린아이의 우유등은 차거워 지지 않도록 한다.Refrigerators or warmers, such as general household appliances, maintain a constant internal temperature at all times to prevent damage to the contents, or to prevent children's milk from becoming cold.
그런데, 이들은 모두 상용전원으로 동작하는 것이므로 평상시 예기치 않는 정전이라든가 또는 외부적 요인(즉 소케트의 접촉불량, 전원코오드의 빠짐, 퓨우즈의 단선등)에 의하여 이러한 물품의 동작이 중지되었을때는 이에따른 적절한 조치를 취하는 것이 바람직하다.However, they all operate on a commercial power source, so when the operation of such an article is stopped due to unexpected power failure or external factors (i.e. poor contact of the socket, missing power cord, disconnection of fuse, etc.). It is desirable to take appropriate measures.
왜냐하면, 냉장고등에 저장된 음식물이 상하거나 하므로서 손실을 가져오지 않도록 정전상태를 알아채서 적절한 조치(즉, 다른 물리적 수단을 이용한)를 취해 놓으면 그만큼 손실이 적어지기 때문이다.This is because if the food stored in the refrigerator or the like is not damaged or damaged, the loss is reduced by recognizing the power failure and taking appropriate measures (that is, using other physical means).
그리고, 주간의 경우에는 이들의 사용빈도가 많으므로 정전상태를 즉시 알아챌수 있으나, 이는 대부분 회로가 복잡함으로 실용적이 못되었고, 특히 평상시에도 릴레이가 여자되어 있다가 정전시 비상장치를 구동시키고 있으므로, 냉장고등은 물론 대형 건축물의 화자나 정전시 비상등 제어장치의 경우에는 대량의 릴레이가 사용되는것이어서 전력낭비가 많게 된다.And, in the case of daytime, because of their frequent use, the power failure state can be recognized immediately, but most of them are not practical due to the complexity of the circuit. Especially, since the relay is energized during normal operation, the emergency device is driven during power failure. In the case of a speaker such as a refrigerator, a large building, or an emergency light control device in case of a power failure, a large amount of relays are used, which causes a lot of power consumption.
본 고안은 이러한 단점을 제거하기위하여 안출된 것으로서, 평상시 릴레이에 직접적인 전원이 가해지지 않아 전력낭비가 없으면서, 비상시 경보를 취할 수 있는 회로를 제공하려는데 그 목적이 있는 것이다.The present invention was devised to eliminate these drawbacks, and the purpose of the present invention is to provide a circuit capable of generating an alarm in an emergency without power waste because no direct power is normally applied to the relay.
이하에서 이를 상세히 설명하면 다음과 같다.This will be described in detail below.
통상의 전원트랜스(T) 2차측에 다이오드(D1) 저항(R1), 컨덴서(C1)로 구성된 "+"전원의 제1정류부(1)를 일측에 연결하고, 그 타측은 다이오드(D2), 저항(R2), 컨덴서(C2)로 구성된 "-"전원의 제2정류부(2)를 연결하되, 상기 제2정류부(2)는 릴레이(Ry) 접점(al,bl)을 거쳐 릴레이(Ry)구동용 트랜지스터(Tr) 의 베이스측에 연결하고, 상기 제1정류부(1)는 밧데리(BT)에 접속됨과 동시에 다이오드(D3), 저항(R5) 및 동작정지용 스위치(S2)를 거쳐 트랜지스터(Tr)의 베이스에, 릴레이(Ry)를 거쳐 트랜지스터(Tr)의 콜렉터에, 상기 릴레이(Ry)의 접점단자(a2,b2)를 거쳐 부저(Bz)에 각각 접속하도록 구성되어있다.The first rectifier 1 of the " + " power source composed of the diode D 1 resistor R 1 and the capacitor C 1 is connected to one side of the secondary power supply T, and the other side thereof is a diode ( D 2 ), the second rectifier (2) of the "-" power source consisting of a resistor (R 2 ), capacitor (C 2 ) is connected, the second rectifier (2) is a relay (Ry) contact (al, bl) Is connected to the base side of the relay Ry driving transistor Tr, and the first rectifying part 1 is connected to the battery BT, and at the same time, a diode D 3 , a resistor R 5 , and a switch for stopping operation. Via (S 2 ) to the base of the transistor (Tr), through the relay (Ry), through the collector of the transistor (Tr), and via the contact terminals (a 2 , b 2 ) of the relay (Ry) to the buzzer (Bz). Each is configured to connect.
미설명부호 AC는 상용전원, R3는 트랜지스터(Tr) 바이서스저항, PL은 파이롯트램프 이다.Unmarked AC is a commercial power supply, R 3 is a transistor (Tr) bias resistor, and PL is a pilot lamp.
이와같이 구성된 본 고안의 작동상태를 설명하면, 동작정지용스위치(S2) 및 동작확인용스위치(S1)를 접속시키면, 제1정류부(1)에서 출력되는 정(+)의 직류전원이 밧데리(BAT)를 충진함과 동시에 다이오드(D3) 및 저항(R5)을 거쳐 트랜지스터(Tr)의 베이스인 C점에 공급되고 또한 릴레이(Ry)를 통하여 트랜지스터(Tr)의 콜렉터에 공급된다. 한편 제2정류부(2)에서 출렬되는 부(-)의 직류전원은 릴레이(Ry)의 접점(a1,b1)를 통하여 상기 C점에 공급된다. 따라서 트랜지스터(Tr)의 베이스(C)의 전압은 상기 제1정류부(1) 및 제2정류부(2)에 의한 전압이 중첩되나, 저항(R1,R2) 및 저항(R3,R5)을 적절히 선택하면 평상시에는 C점에 중첩되어 나타난 전압은 트랜지스터(Tr)를 도통되는데 소요되는 전압 (통상적으로 0.7V)이 되지 못하여 트랜지스터(Tr)는 오프(OFF)된다.Referring to the operation state of the present invention configured as described above, when the operation stop switch (S 2 ) and the operation check switch (S 1 ) is connected, the positive (+) DC power output from the first rectifier 1 is a battery ( At the same time as BAT) is charged, it is supplied to the point C which is the base of the transistor Tr via the diode D 3 and the resistor R 5 , and is supplied to the collector of the transistor Tr through the relay Ry. The negative DC power output from the second rectifying unit 2 is supplied to the point C through the contacts a 1 and b 1 of the relay Ry. Therefore, the voltage of the base C of the transistor Tr overlaps the voltages of the first rectifying unit 1 and the second rectifying unit 2, but the resistors R 1 , R 2 and the resistors R 3 , R 5 If appropriately selected, the voltage superimposed on the point C normally does not become a voltage (normally 0.7V) required to conduct the transistor Tr, and the transistor Tr is turned off.
따라서, 평상시에는 트랜지스터(Tr)이 오프되어 릴레이(Ry)에 전류가 흐르지 아니하므로 거의 전력소모가 없게 된다. 또한 밧데리(BAT)가 충전이 완료되면 파이롯트램프(PL)는 꺼지게 되고 릴레이(Ry)는 작동되지 아니하므로 그 접점(a2,b2)은 개방되어 부자(Bz)는 작동되지 않는다.Therefore, since the transistor Tr is usually turned off and no current flows through the relay Ry, almost no power consumption is achieved. In addition, when the battery BAT is fully charged, the pilot lamp PL is turned off and the relay Ry is not operated. Therefore, the contacts a 2 and b 2 are opened and the rich Bz is not operated.
이때, 동작확인용스위치(S1)를개방하면 제2정류부(2)의 부(-)의 전원이 차단되고 제1정류부(1)의 정(+)의 전원만이 저항(R5,R3)를 통하여 C점에 인가되므로 트랜지스터(Tr)를 도통시키는데 충분한 바이어스 전압(0.7V이상)이 트랜지스터(Tr)베이스에 인가하게 되며, 이로인하여 릴레이(Ry)가 작동되어 접점(a2,b2)가 접속됨과 동시에 접점(a1,b1)가 개방되어 자기유지회로를 형성하면서 부자(Bz)가 계속 작동되므로 본 고안에 의한 회로의 동작상태를 점검할 수 있게된다.At this time, when the operation check switch S 1 is opened, the negative power of the second rectifying unit 2 is cut off, and only the positive power of the first rectifying unit 1 is applied to the resistors R 5 and R. Since it is applied to point C through 3 ), a bias voltage (0.7 V or more) sufficient to conduct the transistor Tr is applied to the transistor Tr base. As a result, the relay Ry is activated to operate the contacts a 2 and b. 2 ) is connected and at the same time the contacts (a 1 , b 1 ) is opened to form a self-maintaining circuit, the rich (Bz) continues to operate, it is possible to check the operating state of the circuit according to the present invention.
한편, 정전이 되면 제1정류부(1) 및 제2정류부(2)로의 AC전원이 차단되어 제2정류부(2)에서 부(-)의 전압이 출력되게 충전된 콘덴서(C2)는 밧데리(BAT)의 정(+)의 전압에 의해 다이오드(D3), 저항(R5,R3)를 통하여 역충전된다. 따라서 이 역충전되는 과정에서 C점의 전압은 0.7V이상으로 되고 이로인하여 트랜지스터(Tr)가 도통되어 릴레이(Ry)가 작동되며, 릴레이(Ry)의 접점(a1,b1)은 개방되고, 접점(a2,b2)은 접속되어 회로 동작상태를 점검할때와 동일하게 되어 부자(Bz)가 계속 작동된다.On the other hand, when a power failure occurs, the AC power supplied to the first rectifying unit 1 and the second rectifying unit 2 is cut off, and the capacitor C 2 charged to output a negative voltage from the second rectifying unit 2 is charged with a battery ( The positive voltage of BAT is reversely charged through the diode D 3 and the resistors R 5 and R 3 . Therefore, in this reverse charging process, the voltage at point C becomes 0.7 V or more, which causes the transistor Tr to conduct, so that the relay Ry is operated, and the contacts a 1 and b 1 of the relay Ry are opened. , The contacts a 2 and b 2 are connected and become the same as when checking the circuit operation state, so that the rich Bz continues to operate.
그후, 부자(Bz)가 동작하여 정전이 되었음을 사용자가 안 경우에는 동작정지용 수동스위치(S2)를 개방하여 더이상 전력소모를 방지토록 한다.After that, when the user (Bz) is operated and the user knows that the power failure is performed, the operation stop manual switch (S 2 ) is opened to prevent further power consumption.
이상과 같이 본 고안은 정전 경보장치로서 회로가 극히 단순하여 냉장고등의 물품에 염가로 용이적용할 수 있고, 정전이 된 이후이어야 릴레이가 동작하게 되므로 전력소모가 없을 정도로 극히 적은등등의 매우 뛰어난 효과가 있다.As described above, the present invention has a very simple circuit as a power failure alarm device, which can be easily applied to articles such as a refrigerator at low cost, and since the relay operates only after a power failure, the effect is very low such that there is no power consumption. There is.
