Description
제1도는 본 고안의 사시도.1 is a perspective view of the present invention.
제2도는 본 고안의 내부 회로로의 일례도.2 is an example of the internal circuit of the present invention.
본 고안은 전원코오드를 구비한 플럭식 누전 차단기에 관한 것으로 에어콘, 클러, 자동판매기, 냉장고 등과 같은 전기 기기의 전원코오드로 사용하여 누전을 검출할 수 있도록 한 것이다.The present invention relates to a flash type circuit breaker with a power cord, and is used as a power cord of an electric device such as an air conditioner, a clutter, a vending machine, a refrigerator, and the like to detect a short circuit.
종래의 누전차단기에 있어서는 배전선로상에 설치하게 되어 있었기 때문에 배전선로상에 병열로 접속연결된 여러가지의 부하(예로서, 세탁기, 냉장고, 에어콘등) 중 1개의 부하에 누전 현상이 발생하게 되면 전체 배전 선로가 차단되게 되는 사용상의 불편이 있었으며, 또한 전체 여러가지 부하중 누전 발생부하를 검지하는 과정에 있어서도 많은 시간과 노력이 요하게 되는 불편이 있었다.In the conventional earth leakage breaker, since it is installed on the power distribution line, when a short circuit occurs in one of various loads (for example, a washing machine, a refrigerator, and an air conditioner) connected in parallel on the power distribution line, the entire power distribution is performed. There was an inconvenience in using the line to be cut off, and also a lot of time and effort was required in the process of detecting an earth leakage generating load among various loads.
본 고안은 상기와 같은 불편을 해소시키기 위하여 누전차단회로와 경보 및 표시부를 내장한 볼트수지 케이스에 플럭과 전원코오드를 설치하여 각종 전기기기의 전원코오드로 사용하므로서 누전 현상이 나타나는 해당 전기기기를 용이하게 식별, 감지할 수 있도록한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the above inconveniences, the present invention easily installs a plug and a power cord in a bolt resin case in which an earth leakage circuit and an alarm and a display unit are installed, and thus is used as a power cord of various electric devices. In order to be able to identify and detect the same, it will be described in detail with reference to the accompanying drawings as follows.
공지한 누전 검출회로부(A)를 개폐기(Ts)의 크로스접점(b)에 접속하고 경보부(B) 및 표시부(C)를 개폐기(Ts)의 오픈접점(a)에 접속시켜 내장한 몰드수지케이스(1)의 외면에 플럭(2)과 전원코오드(3)를 인출하여서 된 것으로 미설명부호 L은 부하이다.Molded resin case in which a known earth leakage detection circuit portion A is connected to the cross contact b of the switch Ts and the alarm portion B and the display portion C are connected to the open contact a of the switch Ts. The plug 2 and power supply cord 3 are drawn out on the outer surface of (1), and reference numeral L denotes a load.
이와 같이 구성된 본 고안은 에어콘, 쿨러, 세탁기, 냉장고, 등과 같은 전기 기기의 전원 코오드로 사용하는 것으로, 부하(L)에 누전이 발생하지 않을 때에는 공지한 누전검출회로부(A)의 영상변류기(Z.C.T)에는 평형 전류가 흐르게 되어 누전신호가 검출되지 않아 증폭부(Q) 또한 동작하지 않게되고 증폭부(Q)의 출력단(S)에 접속된 SCR의 게이트가 차단되어 트립코일(Co)에는 전류가 흐르지 않게 되므로서 개폐기(Ts)는 항시 크로스 접점(b)에 접속되어 부하(L)에 전원을 가하게 되며 오픈접점(a)는 개방되어 있는 상태가 되어 경보부(B) 및 표시램프부(C)는 동작하지 않는 상태가 지속되게 되는 것이다.The present invention configured as described above is used as a power source code of an electric device such as an air conditioner, a cooler, a washing machine, a refrigerator, and the like. ), The balanced current flows so that a short circuit signal is not detected, and thus the amplifier Q is not operated, and the gate of the SCR connected to the output terminal S of the amplifier Q is blocked, so that the current is applied to the trip coil Co. Since it does not flow, the switch Ts is always connected to the cross contact b to apply power to the load L, and the open contact a is in an open state so that the alarm part B and the display lamp part C are open. Is a state of inactivity.
이와 같이 동작하다가 부하(L)에 누전 현상이 발생하게 되면 영상변류기(Z.C.T)에는 불평형 전류가 흐르게되어 누전신호가 검출되고 증폭부(Q)에서 증폭되어 SCR을 트리거시켜 주게되므로서 이와 직렬로 접속된 트립코일(Co)도 여자되어 개폐기(Ts)를 크로스접점(b)에서 오픈접점(a)로 이동시켜 부하(L)의 전원을 차단시켜 주게되는 한편 부저, 벨등으로 구성된 경보부(B)를 동작시켜 경보를 발하게 함과 동시에 표시램프부(C)를 접동시켜 부하(L)에 누전현상이 발생하였다는 신호를 발하게되는 것이다.In this way, when a short circuit occurs in the load L, an unbalanced current flows through the image transformer ZCT, and a short circuit signal is detected and amplified by the amplifier Q to trigger the SCR. The trip coil Co is also excited to move the switch Ts from the cross contact b to the open contact a to cut off the power of the load L, while the alarm part B composed of a buzzer, a bell, etc. By operating the alarm and at the same time, the display lamp (C) is slid to give a signal that a short circuit phenomenon occurs in the load (L).
이와 같이 본 고안에서 항시 오픈 접점(a)에 경보부(B)와 표시램프부(C)는 필요에 따라 선택하여 설치할 수도 있으며, 또한 전원코오드(3)대신에 콘센트를 설치하여도 본 고안과 같은 동일한 작용과 효과를 얻을 수 있음은 물론이다.As such, in the present invention, the alarm unit (B) and the display lamp unit (C) may always be selected and installed in the open contact point (a) as necessary, and an outlet may be installed instead of the power cord (3). Of course, the same action and effect can be obtained.
이와 같이 본 고안은 누전 검출회로부, 경보부, 표시램프부 등을 내장하여 합성수지로 몰딩시킨 몰드수지케이스에 플럭과 전원 코오드를 설치하는 간단한 구조로 형성되어 소형화 할수 있으므로서 염가로 대량 생산하여 각종 전기 기기에 전원코오드로 겸용하여 다수 설치된 각각의 전기 기기에서의 누전 여부를 쉽게 감지할수 있는 특징을 지닌 유용한 고안인 것이다.As such, the present invention has a simple structure in which a plug and a power cord are installed in a molded resin case molded with a synthetic resin by embedding a leakage detection circuit unit, an alarm unit, a display lamp unit, etc., and can be miniaturized. It is a useful design with a feature that can easily detect whether a short circuit occurs in each electric device installed as a power cord.
