A transmitter 10 composed of (3); An ultrasonic sensor 21 for detecting the ultrasonic signal generated by the transmitting side, an ultrasonic-temperature signal converting apparatus 22 for converting the electrical signal received by the ultrasonic sensor into temperature data, and a display device for displaying the detected signal ( And a receiving unit 20 composed of a controller 23 for controlling display on the display unit 24.

이와 같이 구성된 초음파를 이용한 온도검출장치는 송신부(10)의 온도센서(1)에 의해 온도 감지로 상기 온도-초음파 신호 발생기(2)는 감지된 온도에 대칭되는 초음파 신호를 발생시키고, 수신부(20)의 초음파 센서(21)는 송신측에서 발생된 초음파 신호를 감지하여 출력하고, 상기 초음파-온도신호 변환장치(22)는 초음파 센서(21)에서 받아들인 전기신호를 온도 데이터로 변화하여 콘트롤러(23)에서 상기 디스플레이장치(24)에 온도 데이터를 표시하도록 제어하여 이 온도 데이터를 온도 기록계(25)에서 기록하도록 이루어진다.In the temperature detection apparatus using the ultrasonic wave configured as described above, the temperature-ultrasonic signal generator 2 generates an ultrasonic signal symmetric to the sensed temperature by sensing the temperature by the temperature sensor 1 of the transmitter 10, and the receiver 20 Ultrasonic sensor 21 of the sensing unit detects and outputs an ultrasonic signal generated from the transmitting side, and the ultrasonic-temperature signal converter 22 converts the electrical signal received from the ultrasonic sensor 21 into temperature data to control the controller ( 23, the display apparatus 24 is controlled to display temperature data so that the temperature data can be recorded by the temperature recorder 25.

상기 온도검출장치의 작동 및 효과를 설명하면 다음과 같다.Referring to the operation and effect of the temperature detection device as follows.

상기 송신부(10)와 수신부(20)로 이루어진 온도검출장치는 절연된 케이블을 연결시켜주는 접속함의 내부온도를 측정하기 위하여 초음파를 이용한 온도검출장치의 송신부(10)를 도체 슬리브 내부에 장착하고 도체와 차폐층 사이에 350KV의 전압을 인가하고 도체에 2000A의 전류를 흘리면서 온도측정을 실시한다.The temperature detector comprising the transmitter 10 and the receiver 20 mounts the transmitter 10 of the temperature detector using ultrasonic waves inside the conductor sleeve to measure the internal temperature of the junction box connecting the insulated cable.
