Description
차단기는 전기설비의 안정적인 운영을 위하여 발전기와 전기설비와의 접속 또는 전시설비와 다른 전기설비와의 접속등을 수행하는 중요한 전기장치중의 하나이다. 이차단기는 전기설비에 중대한 고장이 발생하였을 경우 조작자의 조작 또는 보호계 전기신호에 의하여 고장구간을 분리하도록 하는 동작코일이 구비되어있다. 하지만 이러한 동작스위치를 통한 차단기의 정상동작 여부검사는 그동작 스위치를 조작하는 경우에만 확인할수있으므로 언제 어떻게 발생될지 모르는 차단기의 고장을 확인하기에는 문제점이 있었고 더욱이 이차단기가 정상적으로 동작되지 않은 경우에는 발생될수 있는 전기적사고에 따른 파급 효과를 생각한다면 차단기의 신뢰도는 반드시 확보되어야 함에도 불구하고 종래의 차단기는 이를 효과적으로 확인 할수 있는 방법이 없음.The breaker is one of the important electrical devices that performs the connection between the generator and the electrical equipment or the exhibition equipment and other electrical equipment for the stable operation of the electrical equipment. The secondary circuit breaker is provided with an operating coil that separates the fault section by the operator's operation or by a protective system electrical signal when a major fault occurs in the electrical equipment. However, the normal operation of the breaker through the operation switch can be checked only when the operation switch is operated. Therefore, there was a problem in confirming the breaker failure, which may or may not occur, and moreover, it may occur when the breaker does not operate normally. Though the reliability of the circuit breaker must be secured when considering the ripple effect due to an electrical accident, a conventional circuit breaker has no way of verifying this effectively.

When a small current mA flows on the light emitting diode, the light is always on.As a result of measuring the distribution terminal voltage at each end of the load, 108V at resistance R2 and about 2V LED (light emitting diode) driving coil X1 is mV. It is also possible to diagnose the disconnection of the breaker operation coil to provide a circuit for detecting the disconnection of the breaker operation nose. Even when the switch is turned on, the current flows through the switch point to drive the circuit breaker operation coil, and the resistor and LED connected in parallel with the operation switch prevent the current from flowing because the current voltage is blocked in the reverse direction. It is possible to check the breaker coil for disconnection using this property.
