본 발명은 차단기의 각 상(R, S, T)의 단자에 대한 측정온도(T)를 제1, 제2, 제3 표출부들을 통해 전시함과 동시에 선택버튼 및 증감버튼의 조작을 각 상의 기준온도인 제1 설정값(TH1, Threshold1)을 조절할 수 있도록 구성됨으로써 조작이 간단하면서 사용의 편의성을 획기적으로 높일 수 있고, 온도감지기를 K-타입 열전대(K type thermocouple)로 구성함과 동시에 차단기의 각 상의 단자에 연결되는 K-타입 열전대들 각각의 '＋', '－' 금속들을 접속시키기 위한 단자부를 포함함으로써 차단기의 3상(R, S, T) 단자들 각각의 온도를 동시 측정할 수 있을 뿐만 아니라 온도감지기의 접속 및 해제가 간편하게 이루어질 수 있으며, 단자덮개부가 투명판을 포함하되 단자덮개부가 하우징에 결합될 때 투명판이 단자들의 단부에 소정 거리 이격되게 설치되도록 구성함으로써 단자 및 온도감지기의 접속여부를 육안으로 확인 가능할 뿐만 아니라 외부로부터의 이물질 유입을 효율적으로 차단하여 검출의 정확성을 높일 수 있고, 차단기의 3상(R, S, T) 단자들 각각의 현재 온도(T) 또는 온도변화율(△T)에 따라 차단기의 전원공급을 제어함으로써 차단기 단자의 발열로 인한 사고를 사전에 정확하게 예측 및 방지할 수 있는 스마트 온도측정기에 관한 것이다. The present invention relates to a smart temperature measuring device wherein temperatures (T) measured with regard to terminals of respective phases (R, S, T) of a circuit breaker are displayed through first, second, and third display units, and the same comprises a selection button and an increase/decrease button configured such that, through manipulations thereof, the first setting value threshold1 (TH1), which is the reference temperature of each phase, can be adjusted, thereby simplifying manipulations and substantially improving convenience in use; the same comprises a temperature sensing device, which is configured by a K-type thermocouple, and terminal portions for connecting "+" and "-" metals of respective K-type thermocouples that are connected to terminals of respective phases of the circuit breaker, thereby making it possible to simultaneously measure the temperature of the terminal of each of the three phases (R, S, T) of the circuit breaker, and facilitating the connection and disconnection of the temperature sensing device; the terminal cover portion comprises a transparent plate configured such that, when the terminal cover portion is coupled to the housing, the transparent plate is installed to be spaced from the ends of the terminals by a predetermined distance, thereby making it possible to confirm by the naked eye whether the terminals and the temperature sensing device are connected or not, and improving the accuracy of detection through efficient blocking of inflow of alien substances from the outside; and power supply to the circuit breaker is controlled according to the current temperature (T) of the terminal of each of the three phases (R, S, T) of the circuit breaker or according to the rate of temperature change (ΔT) thereof, thereby accurately predicting and preventing any accident, which would otherwise occur due to heating of the terminals of the circuit breaker, in advance.
