Description

누전차단기의 누전 테스트장치{the earth leakage test device in leakage circuit breaker}The earth leakage test device in leakage circuit breaker}

본 발명은 전선의 보호와 부하의 개폐 및 누전발생시 회로의 차단을 목적으로 사용되는 산업용 전기기기인 누전차단기에 관한 것으로, 보다 상세하게는 누전차단기의 기구부가 정상적으로 동작하고 있는지의 여부를 확인하기 위한 누전 테스트장치에 관한 것이다.The present invention relates to an earth leakage circuit breaker, which is an industrial electrical device used for the purpose of protecting wires, opening and closing loads, and interrupting circuits in the event of a short circuit. The present invention relates to a ground fault test apparatus.

누전차단기는 누설전류나 지락 또는 인체 감전사고 등의 발생시 이상전류를 검출하여 회로를 차단함으로서 부하측의 설비 및 인명을 보호하는 기기이며, 과전류차단과 누전차단 및 회로개폐 등의 주요기능을 가지고 있다.An earth leakage breaker is a device that protects the equipment and life of the load by detecting an abnormal current in case of leakage current, ground fault or human electric shock, and cuts off the circuit. It has the main functions such as over current interruption, earth leakage breaker and circuit breaker.

또한 누전차단기는 도 2 내지 도 4와 크게 나누어 케이스(1) 및 커버(2)와, 전원측 단자대(3)로 부터 들어오는 과전류나 이상전류를 검출하는 검출부(4)와, 상기 검출부에서 검출된 전류를 감지하여 회로 차단여부를 판단하고 사고전류 판명시 구동부로 신호를 전송하는 회로부(5)와, 상기 회로부로 부터 전송된 신호에 의해 동작하는 전자장치부(6)와, 상기 전자장치부의 동작에 따라 구동하여 트립(Trip)작동시 전원측 단자대로 들어오는 전류가 부하측 단자대(7)로 흐르는 것을 차단하여 주는 크로스바(9)를 가진 기구부(8)와, 트립된 상태의 차단기를 리셋하여 재투입시키는 핸들(10)등으로 구성되어 있다.In addition, the earth leakage breaker is largely divided from FIG. 2 to FIG. 4 to detect the overcurrent or abnormal current from the case 1 and the cover 2, the power supply terminal block 3, and the current detected by the detection unit. To detect whether the circuit is cut off and determine whether the circuit breaks, and transmits a signal to the driver when the fault current is determined, an electronic device 6 operated by a signal transmitted from the circuit, and according to the operation of the electronic device. The drive unit has a cross-section (9) having a crossbar (9) for driving to block the current flowing into the terminal block of the power supply terminal during the trip operation, and the circuit breaker in the tripped state to reset and re-enter the circuit ( 10) and so on.

따라서 이상전류의 검출에 의해 회로부(5)에서 신호가 전송되어 트립코일에 전류가 흐르면 이 전류에 의해 영구자석(도시는 생략함)의 자력이 상실되면서 트립레버(도시는 생략함)가 회전하여 기구부((8)의 크로스바(9)를 타격하게 되고 동시에 기구부(8)의 트립동작이 이루어져 전류는 차단된다.Therefore, when a signal is transmitted from the circuit part 5 by the detection of an abnormal current and a current flows in the trip coil, the magnetic force of the permanent magnet (not shown) is lost by this current, and the trip lever (not shown) rotates. The crossbar 9 of the mechanism 8 is hit and at the same time a tripping operation of the mechanism 8 is performed to cut off the current.

또한 상기와 같은 누전차단기에는 도 1과 같이 누전 테스트버튼(11)이 설치되어 사용자가 누전 테스트버튼을 누름에 따라 누전 차단기능이 제대로 작동하는지의 여부를 확인할 수 있게 하고 있다.In addition, the ground fault circuit breaker as described above is provided with a ground fault test button 11 as shown in FIG. 1 to allow the user to check whether the ground fault breaking function is properly operated as the user presses the ground fault test button.

그러나 배선용 차단기능과 누전 차단기능을 모두 가지고 있는 누전차단기에서 누전 차단기능의 확인을 위한 누전 테스트버튼(11)만 설치되어 있는 경우 기구부의 정확히 동작하는지의 여부는 확인할 수 없다.However, in the ground fault circuit breaker having both the circuit breaker and the ground fault breaker function, if only the ground fault test button 11 is installed for checking the ground fault breaker function, it is impossible to confirm whether the mechanism part operates correctly.

즉, 사용자가 누전 테스트버튼(11)을 눌렀을 때 정확히 작동하지 않는 경우(기구부가 트립되지 않는 경우) 그 원인이 회로부(5)와 전자장치부(6) 등 누전 기능부의 오류인지, 아니면 기구부(8)의 오류인지를 판별하기 어려운 결점이 있다.That is, if the user does not operate correctly when the user presses the ground fault test button 11 (the mechanism is not tripped), the cause is an error of the ground fault function such as the circuit unit 5 and the electronic device unit 6, or the mechanism unit 8 It is difficult to determine if the error is

본 발명의 목적은 누전차단기에 기구부의 동작을 확인할 수 있는 트립버튼을 추가로 설치하여 누전 테스트 기능이 제대로 동작하지 않는 경우 그 원인이 무엇인가를 사용자가 쉽게 판별할 수 있도록 한 것이다.An object of the present invention is to further install a trip button that can confirm the operation of the mechanism portion to the earth leakage breaker so that the user can easily determine the cause of the earth leakage test function does not work properly.
