본 발명은 손상 검출수단이 구비된 케이블 구조에 관한 것이다.The present invention relates to a cable structure provided with damage detection means.

일반적으로 통신 또는 전력 케이블은 제1도에 도시된 바와같이, 내부도체(1)를 절연시키는 절연코아(2)와, 그 외부에 씌워져 케이블 전체를 보호하는 합성수지제의 자켓(3)으로 구성되어 있다.In general, a communication or power cable is composed of an insulation core 2 for insulating the inner conductor 1 and a jacket 3 made of synthetic resin that is covered on the outside to protect the entire cable as shown in FIG. have.

그런데 케이블의 포설작업시나 기타 매설공사의 굴삭에 수반하는 공중과실 및 지반 침하등의 자연재해, 또는 설치류등으로 인하여 케이블이 외력을 받을 경우, 케이블 자켓이 찢어지는 등의 손상이 종종 발생하게 된다.However, when the cable is subjected to external forces due to aerial disasters, ground subsidence, or rodents, etc., which occur during the laying of the cable or other burial work, damage to the cable jacket is often caused.

이러한 케이블 자켓의 손상은 손상부분으로 물 또는 수분의 유입이 가능하게 되어 케이블 열화 또는 성능저하를 초래할 수 있고, 자켓 내부의 절연코아에까지 손상부위가 확대될 경우에 계기치 못한 심각한 대형사고마저 초래할 위험성이 내포되어 있다.The damage of the cable jacket can cause water or moisture to enter the damaged part, which can lead to cable deterioration or deterioration of performance, and the risk of even serious accidents that are not caused when the damaged part is extended to the insulation core inside the jacket. Is implied.

따라서, 통신 또는 전력 케이블에는 이러한 케이블의 손상을 검출할 수 있는 수단이 요구되는바, 지금까지는 육안에 의한 손상부위의 식별에만 의존하고 있는 형편이어서 수시로 작업자가 케이블을 일일이 점검해야 하는 불편이 있었고, 더우기 육안으로 확인할 수 없는 위치에 설치된 케이블의 경우에는 검출자체가 전혀 불가능한 실정이었다.Therefore, a communication or power cable requires a means for detecting such cable damage. Until now, it has been inconvenient to rely on the identification of damaged parts by the naked eye, and the operator has to check the cable from time to time. In addition, in the case of cables installed in a location that cannot be seen with the naked eye, the detection itself was impossible.

본 발명은 이와같은 종래의 제반 문제점을 해소하기 위하여 연구된 것으로서, 케이블 자체에 손상부위를 검출할 수 있는 수단을 내장시켜 제조함으로써 케이블이 손상됐을 때 그 사실이 즉시 외부에서 검출가능하게하여 케이블 손상으로 인한 피해를 최소화할 수 있도록 한 것이다.The present invention has been studied in order to solve such a conventional problem, by manufacturing a built-in means for detecting damage to the cable itself by the fact that when the cable is damaged that can be immediately detected from the outside damage the cable It is to minimize the damage caused by.

이하 본 발명을 첨부 도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명에 의한 케이블 단면도로서, 내부도체(1)와, 이를 외부와 절연시키는 절연코아(2) 및, 절연코아(2)를 감싸 케이블 전체를 보호하는 자켓(3)등으로 구성된 케이블에 있어서, 상기 자켓(3) 내부에 알루미늄이나 동, 은 등의 양도전성금속의 박판 또는 극세선으로 된 다수의 검출도체(4)를 등간격의 케이블 종축방향으로 메설하여 자켓(3)의 손상시 발생되는 검출도체(4)의 단선을 외부에서 측정 가능케 함으로써 케이블의 손상이 간편히 검출될 수 있도록 한 구조로서, 상기 검출도체(4)는 손상부위를 보다 광범위하게 검출할 수 있게 하기 위하여 그 매설간격이 좁을 수록 바람직하다.2 is a cross-sectional view of the cable according to the present invention, which includes an inner conductor 1, an insulation core 2 for insulating it from the outside, and a jacket 3 for covering the insulation core 2 to protect the entire cable. In the jacket 3, a plurality of detection conductors 4 made of a thin plate or an ultra fine wire of a conductive metal such as aluminum, copper, silver, etc. are embedded in the longitudinal direction of the cable at equal intervals to damage the jacket 3. The disconnection of the detection conductor (4) generated at the time can be measured from the outside so that damage to the cable can be easily detected, and the detection conductor (4) is buried so that the damage portion can be detected more extensively. The narrower the interval, the better.

이와같이 구성된 본 발명의 케이블 구조는 자켓(3) 내부에 검출도체(4)가 매설되어 있기 때문에 케이블에 외력이 가해져 자켓(3)에 손상이 올경우 발생되는 검출도체(4)의 단선이 검출도체(4)와 연결된 외부 검출장치에서 바로인식되어 케이블의 손상유무가 검출되게 함으로써, 케이블이 설치된 장소에 구애받지 않고 모든 케이블의 손상여부를 외부에서 즉시 검출할 수 있는 효과가 있다. 그리고 이와같은 본 발명은 상기 실시예에서는 기본적인 구조의 케이블에 본 발명을 적용한 경우가 예시되었으나, 본 발명의 기술적 목적이 요구되는 기타 어떤구조의 다른 케이블에도 그 적용이 물론 가능하다.In the cable structure of the present invention configured as described above, since the detection conductor 4 is embedded in the jacket 3, the disconnection of the detection conductor 4, which is generated when an external force is applied to the cable and damages the jacket 3, is detected. By immediately recognizing the damage of the cable detected by the external detection device connected to (4), there is an effect that can immediately detect the damage of all the cables from the outside regardless of the place where the cable is installed. In the above embodiment, the present invention has been exemplified in the case where the present invention is applied to a cable having a basic structure. However, the present invention can be applied to any other cable having any other structure requiring the technical object of the present invention.
