누전차단기의 과열방지장치{Overheating check apparatus of leakage of electricity breaker}Overheating check device of earth leakage breaker {Overheating check apparatus of leakage of electricity breaker}

본 발명은 누전차단기의 과열방지장치, 보다 상세하게는 전기수용가의 인입구에 설치되어 부하측에서 발생되는 누전이나 과전류 등을 차단하는 누전차단기에 입력측 접점부에서 발생되는 과열을 자동으로 감지하여 상기 누전차단기를 차단되게 하는 기능을 부여하여 도선의 열화 및 화재 등을 방지할 수 있게한 누전차단기의 과열방지장치에 관한 것이다.The present invention is an overheat protection device of the earth leakage breaker, more specifically, it is installed at the inlet of the electric receiver, the earth leakage breaker that cuts the short circuit or overcurrent generated in the load side automatically detects the overheat generated in the input side contact portion the earth leakage breaker The present invention relates to an overheat prevention device of an earth leakage circuit breaker that prevents deterioration and fire of a wire by providing a function of blocking the wire.

일반적으로, 전기를 사용하고 있는 모든 장소에는 누전이나 과전류로 인한 각종 사고를 미연에 방지하기 위한 목적으로 전기의 사용량이 누적되는 적산전력계로부터 부하측의 사이에 누전차단기를 설치 및 사용하고 있다.In general, in all places where electricity is used, an earth leakage breaker is installed between the load side and the integrated power meter in which the amount of electricity is accumulated for the purpose of preventing various kinds of accidents due to short circuit or overcurrent.

도 1은 일반적인 누전차단기의 설치상태를 개략적으로 나타낸 계통도로서, 입력측으로부터 송전되는 전압이 누전차단기(1)를 경유하여 수용가의 부하측으로 공급되어 사용되는 과정에서 예기치 않은 누전이나 감전 등의 요인에 의해 순간적으로 높은 과전류가 흐를때 이 과전류의 흐름을 누전차단기가 감지하여 부하측으로 공급되는 전원을 차단시키는 작용을 하였다.1 is a schematic diagram showing the installation state of a general earth leakage breaker. In the process in which the voltage transmitted from the input side is supplied to the load side of the consumer via the earth leakage breaker 1 and is used, it may be caused by an unexpected earth leakage or electric shock. When the high current flows momentarily, the earth leakage breaker senses the flow of the over current and cuts off the power supply to the load side.

그러므로 상기 종래의 누전차단기는 수용가에서 전기를 사용할 때 발생되는 각종 유형의 사고에 대하여는 거의 완벽한 대처가 가능한 장점이 있으므로, 전기안전규칙에 의거하여 그 사용이 의무화되어 있다.Therefore, the conventional earth leakage breaker has the advantage that it can almost cope with various types of accidents generated when using electricity in the consumer, and its use is mandatory according to the electrical safety rules.

그러나, 상기 대부분의 누전차단기는 전압을 공급하기 위해 입력측 도선이 연결되는 접점부의 결함이나 접촉불량에 의해 발생되는 과열에 대해서는 무방비한 상태이므로, 상기 접점부에서 예기치 않게 과열이 발생된 경우에는 누전차단기에 열화를 미치게 되면서 그 동작의 정확도를 저하시키거나 심한 경우 화재의 원인을 제공하는 등의 심각한 문제점을 내포하고 있었다.However, most of the circuit breakers are defenseless against overheating caused by a defect or contact failure of a contact portion to which an input wire is connected to supply a voltage. As a result of the deterioration of the system, serious problems such as lowering the accuracy of the operation or providing a cause of fire in severe cases were included.

즉, 누전차단기의 입력측 접점부에서 발생된 과열에 의해 누전차단기의 각 부품 및 회로가 열화될 경우 누전차단기의 동작 저하는 물론 본래의 누전차단기능을 상실하면서 과전류의 발생으로 인하여 사고가 발생될 경우 그 원인을 제대로 파악하지 못하는 문제점이 있었다.That is, when each component and circuit of the ground fault circuit breaker is deteriorated by the overheating generated at the input side of the ground fault breaker, the operation of the ground fault breaker is reduced and the accident occurs due to the occurrence of overcurrent while losing the original ground fault breaker function. There was a problem that did not properly determine the cause.

본 발명은 위와 같은 종래의 누전차단기의 문제점을 감안하여 안출한 것으로, 그 목적은 누전차단기의 입력측 접점부에서 발생되는 결함으로 인한 과열을 감지할 수 있는 누전차단기의 과열방지장치를 제공하는 것이다.The present invention has been made in view of the problems of the conventional ground fault circuit breaker, and an object thereof is to provide an overheat protection device of a ground fault circuit breaker capable of detecting overheating caused by a defect occurring at an input side contact portion of the ground fault circuit breaker.

이러한 목적을 달성하기 위한 본 발명은, 입력측 도선이 연결되는 누전차단기의 접속부에 설정치 이상의 온도를 감지하는 온도센서를 근접되게 설치하고, 상기 누전차단기의 내부에는 온도센서에서 감지된 신호에 의해 누전차단기의 스위치를 차단되게 구동시키는 차단기 구동회로를 장착함으로써, 상기 누전차단기가 수용가의 부하측에서 발생되는 누전 및 과전류를 차단시키는 고유의 기능외에 반대측의 입력측 접점부 결함으로 인한 과열을 방지함을 특징으로 한다.In order to achieve the above object, the present invention includes a temperature sensor detecting a temperature higher than a set value close to a connection portion of an earth leakage breaker to which an input side lead is connected, and an earth leakage breaker by a signal detected by a temperature sensor inside the earth leakage breaker. By installing a circuit breaker driving circuit for driving the switch of the circuit breaker, the circuit breaker prevents overheating due to the fault of the input side contact portion on the opposite side in addition to the inherent function of blocking the short circuit and overcurrent generated on the load side of the consumer. .

이하, 본 발명의 누전차단기의 과열방지장치를 첨부도면을 참조하여 설명하면 다음과 같다.Hereinafter, the overheat prevention device of the earth leakage breaker of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명의 실시예에 의한 과열방지장치가 적용된 누전차단기의 설치상태를 나타낸 계통도로서, 수용가에 전기를 공급하기 위한 입력측(I)으로부터 도선을 통해 누전차단기(10)의 접속부(11)에 연결되고, 상기 접속부(11)의 타단에는 수용가의 부하측(P)이 연결되어 있다.FIG. 2 is a system diagram showing an installation state of an earth leakage breaker to which an overheat prevention device according to an embodiment of the present invention is applied, and the connection portion 11 of the earth leakage breaker 10 through a wire from an input side I for supplying electricity to a consumer. The other end of the connecting portion 11 is connected to the load side P of the consumer.

즉, 상기 입력측(I)과 부하측(P)의 사이에 누전차단기(10)가 설치됨으로 인하여 부하측에서 발생되는 누전 또는 과전류 등을 차단하는 일반적인 누전차단기의 기능을 수행한다.That is, the earth leakage breaker 10 is installed between the input side I and the load side P to perform a function of a general earth leakage breaker that cuts out a short circuit or an overcurrent generated in the load side.

입력측 도선이 연결되는 누전차단기(10)의 접속부(11)에 인접된 부위에는 통전과정에서 접속부의 접촉불량에 의해 과열이 발생될 때 설정치 이상의 온도를 감지하는 온도센서(20)가 설치되고, 상기 누전차단기(10)의 내부에는 온도센서(20)에서 감지된 신호가 입력되어 누전차단기의 스위치를 차단되게 구동시키는 차단기 구동회로(30)가 설치되어 있다.A temperature sensor 20 is installed at a portion adjacent to the connection portion 11 of the earth leakage breaker 10 to which the input side conductor is connected, to detect a temperature higher than or equal to a set value when overheating occurs due to a poor contact of the connection portion in the energization process. The circuit breaker driving circuit 30 is installed inside the ground fault circuit breaker 10 to drive a signal sensed by the temperature sensor 20 to shut off the switch of the ground fault circuit breaker.

따라서, 상기와 같은 본 발명은 외부의 전원이 공급되는 입력측(I)과 수용가의 부하측(P) 사이에 통상적인 방법으로 누전차단기(10)를 설치함으로써, 수용가의 부하측에서 발생될 수 있는 누전 및 감전 등의 요인에 의한 과전류를 차단시키는 고유의 기능을 수행하는 한편, 입력측 도선이 연결된 접속부(11)의 주변온도가 온도센서(20)에 의해 지속적으로 감지되고, 감지된 온도신호가 차단기 구동회로(30)에 입력되어 입력된 온도신호가 설정 온도보다 높을 경우 누전차단기(10)의 스위치를 차단시키게 된다.Accordingly, the present invention as described above by installing a circuit breaker 10 in a conventional manner between the input side (I) to which the external power is supplied and the load side (P) of the consumer, the electric leakage that can be generated on the load side of the consumer and While performing an inherent function of blocking an overcurrent caused by electric shock or other factors, the ambient temperature of the connecting portion 11 to which the input side wire is connected is continuously detected by the temperature sensor 20, and the sensed temperature signal is detected by the circuit breaker driving circuit. When the temperature signal inputted to the input signal 30 is higher than the set temperature, the switch of the earth leakage breaker 10 is cut off.

그러므로, 누전차단기(10)를 매개로 수용가에서 발생되는 과전류는 물론 입력측(I)으로부터 누전차단기에 가해질 수 있는 사고 요인을 미연에 차단하여 누전차단기를 보호하게 됨으로써, 누전차단기의 열화나 수명단축 등을 방지하고 사용의 안전성을 극대화할 수 있는 것이다.Therefore, the earth leakage breaker 10 protects the earth leakage breaker by preventing accidents that may be applied to the earth leakage breaker from the input side I as well as the overcurrent generated in the consumer through the earth leakage breaker 10, thereby deteriorating the life of the earth leakage breaker, etc. To prevent and maximize the safety of use.

이와 같은 본 발명의 누전차단기의 과열방지장치는 기존 누전차단기를 이용하여 입력측으로부터 누전차단기에 가해질 수 있는 변형요인에 자동으로 대응할 수 있는 안전장치를 부여함으로써, 누전차단기의 성능 및 기능저하로 인한 오동작을미연에 방지함은 물론 사용수명을 연장할 수 있는 효과가 있으며, 전기수용가에는 더욱 안전하게 전기를 공급할 수 있는 등의 장점도 있다.The overheat prevention device of the earth leakage breaker of the present invention by using the existing earth leakage breaker by providing a safety device that can automatically respond to the deformation factors that can be applied to the earth leakage breaker from the input side, the malfunction due to the performance and functional degradation of the earth leakage breaker In addition to preventing them, it has the effect of prolonging the service life, and also has the advantage of providing electricity to electric customers more safely.
