Abstract

본 발명은 화재발생인식 수단이 구비된 케이블 구조에 관한 것으로서, 케이블의 화재발생을 지금까지는 케이블 주위에 설치된 화재경보기에만 의존하여 왔으나, 본 발명은 케이블의 절연코아(3) 외측의 자켈(5) 내부에 복수1조의 금속도체로 된 경보선(6)을 케이블 종축방향으로 내장하여 화재발생시 상승하는 경보선(6)의 저항 중가에 이은 단선 저항의 인식에 의하여 화재발생을 외부에서 신속 정확히 감지할 수 있도록 한 것이다.The present invention relates to a cable structure provided with a fire generating means, the fire generation of the cable until now has been dependent only on the fire alarms installed around the cable, the present invention is a jackel (5) outside the insulation core (3) of the cable The alarm line 6 made of a plurality of sets of metal conductors is installed in the longitudinal direction of the cable to detect the fire quickly and accurately from the outside by recognizing the disconnection resistance following the resistance increase of the alarm line 6 which rises in case of fire. I would have to.

Claims

In a cable composed of an inner conductor 1, an insulation core 3 that insulates it from the outside, and a jackel 5, etc., a plurality of sets of alarm lines inside the jackel 5 outside the insulation core 3 6) is built in the longitudinal direction of the cable fire detection means characterized in that it is possible to detect the fire of the cable from the outside by recognizing the disconnection resistance following the resistance of the alarm line (6) which rises in the event of a fire. This provided cable structure.

2. The cable structure according to claim 1, wherein the alarm line (6) is covered with an insulator (7) and embedded therein.

The cable structure according to claim 1 or 2, wherein the alarm line (6) is formed of a thin plate or an ultra fine wire of a conductive metal.

※ Note: The disclosure is based on the initial application.
