The present invention relates to an IoT system for monitoring a strain insulator in a distribution line. As transmission line and distribution line often pass through a mountainous area in which trees are dense, when arc discharge occurs in a power line installed in the mountainous area, there is a risk of a large-scale fire such as a forest fire. The present invention relates to the IoT system for monitoring a fire in a distribution line which can detect occurrence or occurrence possibility of arc discharge in advance at a connection part of a strain insulator device in the distribution line and inform a management server or the like through an IoT communication network. In addition, an IoT sensor module included in the present invention is mounted on a pole or a pylon in which the strain insulator is installed, and when series arc discharge occurs due to poor contact or disconnection at the connection part or the like, can automatically detect the arc discharge and transmit a signal through the IoT communication network. Moreover, a monitoring server receiving the signal analyzes a signal transmitted from the other sensor module to quickly find an area in which a fire is expected to occur, thereby preventing a large-scale fire such as a forest fire from developing. 본 발명은 배전선로 내장애자 감시 IoT시스템에 관한 것이다. 송전선로나 배전선로는 수목이 울창한 산악지역을 통과하는 경우가 많은데, 산악지역에 설치된 전선로에서 아크방전이 발생하면 산불 등의 대형화재로 번질 위험이 있다. 본 발명은 배전선로 중 내장애자 장치의 연결 부위 등에서 아크방전이 발생하거나 발생 가능성을 사전에 감지하여 사물인터넷 통신망을 통하여 관리서버 등에 알려줄 수 있는, 배전선로의 화재감시용 IoT시스템에 관한 것이다. 본 발명에 포함되는 IoT 센서모듈은, 내장애자가 설치된 전주나 철탑 상에 장착되어, 연결 부위 등에서 접촉 불량이나 단선 등의 사유로 직렬 아크방전이 발생하는 경우, 이를 자동으로 감지하여 IoT 통신망을 통하여 신호를 송출할 수 있고, 이를 수신한 감시서버가 다른 센서모듈로에서 송출하는 신호까지 분석하여 화재발생이 예상되는 지역을 신속하게 찾아내므로 산불 등의 대형화재로 발전되는 것을 예방할 수 있게 된다.
