Description

누수감지케이블{CABLE FOR DETECTING A WATER LEAKAGE}Leak Detection Cable {CABLE FOR DETECTING A WATER LEAKAGE}

본 고안은 누수감지케이블에 관한 것으로서, 특히 누수감지능을 증대시키도록 케이블의 단위 길이당 감지선의 표면적을 넓힐 수 있는 누수감지케이블에 관한 것이다.The present invention relates to a leak detection cable, and more particularly to a leak detection cable that can increase the surface area of the sensing line per unit length of the cable to increase the leak detection capability.

항온항습실이나 전산실, 크린룸 등 각종의 시설물은 전도성 액체에 의해 내부설비에 악영향이 가해질 수 있으므로 습기나 누수, 누유 등을 정확히 계측하여후속조치를 취할 수 있도록 하는 감지수단이 필수적으로 요구된다.Various facilities such as a constant temperature and humidity room, a computer room, and a clean room may adversely affect the internal equipment by a conductive liquid, and thus, a sensing means for accurately measuring moisture, leakage, and leakage may be required to take further action.

그러나, 일반적으로 시설물은 그 점유면적을 고려했을 때 센싱이 이루어져야 할 지점이 무수하므로 통상의 습도감지소자로는 소기의 목적을 달성하는 것이 곤란하다.However, in general, the facility has a number of points to be sensed in consideration of its occupied area, so it is difficult to achieve the desired purpose with a normal humidity sensing element.

이러한 문제의 대안으로는 '레이켐 케이블'로 알려진 케이블 형태의 누수감지수단(이하 누수감지케이블로 지칭)을 들 수 있다. 이것은 도 1에 도시된 바와 같이 외부시스(10) 내에 두 개의 신호선(15)과 두 개의 감지선(혹은 저항선)(20)이 각각 종입되고, 케이블의 종단은 보통 신호선(15)과 감지선(20)이 쌍을 이루며 서로 연결된 구성을 갖는다.An alternative to this problem is a leak detection means (hereinafter referred to as a leak detection cable) in the form of a cable known as 'laychem cable'. As shown in FIG. 1, two signal lines 15 and two sensing lines (or resistance lines) 20 are respectively inserted in the outer sheath 10, and the ends of the cable are usually the signal lines 15 and the sensing lines ( 20) paired and connected to each other.

상기와 같은 구성을 갖는 누수감지케이블은 케이블의 특정지점에 수분과 같은 전도성 액체가 접촉되어 누설전류가 생길 경우 이를 감지하도록 회로모듈과 연결이 된다.The leak detection cable having the above configuration is connected to a circuit module to detect when a leakage current occurs due to contact with a conductive liquid such as moisture at a specific point of the cable.

누수감지케이블은 누수감지 대상이 되는 지점에 케이블을 늘어뜨리는 것만으로 포설이 이루어지므로 사용이 편리하고, 포설면적에 거의 제한을 받지 않는 장점이 있다. 그러나, 현재 사용되고 있는 누수감지케이블은 도 1에 도시된 바와 같이 케이블의 길이방향과 나란하게 각각의 신호선(15)과 감지선(20)이 종입되므로 케이블의 단위길이당 누수감지효율은 그다지 높지 않은 취약점이 있다.Leakage detection cable is easy to use because it is laid just by laying the cable to the point to be leak detection, there is an advantage that the installation area is hardly limited. However, the leak detection cable currently being used has a signal leakage efficiency per unit length of the cable is not so high because each signal line 15 and the sensing line 20 is inserted in parallel with the longitudinal direction of the cable as shown in FIG. There is a vulnerability.

본 고안은 상기와 같은 점을 고려하여 창안된 것으로서, 케이블의 단위길이당 누수감지효율을 향상시킬 수 있는 누수감지케이블을 제공하는데 그 목적이 있다.The present invention was conceived in view of the above, and an object thereof is to provide a leak detection cable that can improve the leak detection efficiency per unit length of a cable.

이하, 첨부된 도면을 참조하여 본 고안의 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 고안의 바람직한 실시예에 따른 누수감지케이블의 구성을 도시하는 절개사시도이다.Figure 2 is a cutaway perspective view showing the configuration of the leak detection cable according to an embodiment of the present invention.

도 2를 참조하면, 본 고안은 신호선(105) 및 감지선(110)을 포함하되, 상기 신호선(105)과 감지선(110)이 케이블의 길이방향을 따라 꼬인(twisted)구조를 갖는다. 여기서, 상기 신호선(105)과 감지선(110)의 작용은 통상의 누수감지케이블과 동일하다.Referring to FIG. 2, the present invention includes a signal line 105 and a sensing line 110, wherein the signal line 105 and the sensing line 110 have a twisted structure along the cable length direction. Here, the action of the signal line 105 and the sensing line 110 is the same as the conventional leak detection cable.

상기 신호선(105)과 감지선(110)은, 도 3에 도시된 바와 같이 상호 대향하도록 집합됨과 더불어, 케이블의 길이방향을 따라 나선형으로 꼬인구조를 갖는다. 여기서, 케이블 종단에서의 상기 신호선(105)과 감지선(110)의 결속구조(미도시)는통상의 기술이 동일하게 채용될 수 있다.The signal line 105 and the sensing line 110 are assembled to face each other as shown in FIG. 3 and have a spirally twisted structure along the longitudinal direction of the cable. Here, as for the binding structure (not shown) of the signal line 105 and the sensing line 110 at the cable end, the same general technology may be employed.

상기 신호선(105)은 방수를 위해 PVC(폴리염화비닐)와 같은 방수재(106)로 피복되는 것이 바람직하다. 이때, 상기 신호선(105)의 심선 소재로는 수분에 대한 내성이 강한 스테인레스 계열의 도체가 사용되는 것이 바람직하다.The signal line 105 is preferably coated with a waterproofing material 106 such as PVC (polyvinyl chloride) for waterproofing. In this case, as the core material of the signal line 105, a stainless series conductor having strong resistance to moisture is preferably used.

또한, 상기 감지선(110)은 흡습성이 우수한 절연재(111)로 피복되는 것이 바람직하다. 이러한 소재로는 면사나 레이온이 바람직하게 채용될 수 있다.In addition, the sensing line 110 is preferably coated with an insulating material 111 excellent in hygroscopicity. As such a material, cotton yarn or rayon can be preferably used.

도 4에는 본 고안에 따른 누수감지케이블(S)의 사용예가 도시되어 있다. 도면을 참조하면, 본 고안은 시설물 내의 각 설비(1) 등 도전성 액체에 취약한 부분이나 누수가 우려되는 지점에 상응하여 늘어뜨려짐으로써 포설이 이루어진다. 비록, 도면에는 도시되지 않았으나, 본 고안에 따른 누수감지케이블(S)은 그 종단에 소정의 커넥터를 결합하여 필요에 따라 길이를 연장하여 사용할 수도 있다.Figure 4 shows an example of the use of the leak detection cable (S) according to the present invention. Referring to the drawings, the present invention is laid by corresponding to the parts vulnerable to the conductive liquid, such as each facility (1) in the facility or the point where the leak is concerned. Although not shown in the drawings, the leak detection cable (S) according to the present invention may be used by extending the length as necessary by coupling a predetermined connector to its end.

본 고안에 따른 누수감지케이블(S)은 실질적으로 케이블 내에서 발생된 누설전류를 감지하는 회로가 구비된 감지모듈(3)의 해당 단자에 연결이 되며, 상기 감지모듈(3)로부터 감지데이터를 전송받아 소정의 표시부(미도시)에 누수상태를 표시하거나 다중의 감지모듈(3)을 통합적으로 제어하는 콘트롤러(2)에 직접적으로 연결될 수도 있다. 이러한 콘트롤러(2)는 입력받은 데이터를 분석하여 누설전류가 흐르는 지점의 위치도 산출해 낼 수 있다.The leak detection cable (S) according to the present invention is connected to a corresponding terminal of the detection module (3) having a circuit for detecting a leakage current generated in the cable substantially, the detection data from the detection module (3) It may be directly connected to the controller 2 which receives the received water and displays a leak state on a predetermined display unit (not shown) or controls the multiple sensing modules 3 integrally. The controller 2 may also calculate the position of the leakage current flow point by analyzing the received data.

이상과 같은 본 고안은 케이블의 길이방향을 따라 신호선(105)과 감지선(110)이 나선형으로 꼬인구조로 집합되므로 전도성 유체와 접촉되는 감지선(110)의 유효면적이 종래에 비해 증대된 상태로 포설이 이루어진다.According to the present invention as described above, since the signal line 105 and the sensing line 110 are assembled in a spiral twisted structure along the longitudinal direction of the cable, the effective area of the sensing line 110 in contact with the conductive fluid is increased compared with the conventional state. Installation is done.

따라서, 상기 신호선(105)에 신호를 인가한 상태에서 감지선(110)에 수분 등이 접촉되면 종래에 비해 향상된 감지효율 및 감지용량으로 누설전류의 감지동작이 이루어지게 된다.Therefore, when moisture or the like comes into contact with the sensing line 110 in a state where a signal is applied to the signal line 105, the leakage current is sensed with improved sensing efficiency and sensing capacity than in the related art.

이상, 본 고안의 바람직한 실시예를 첨부된 도면들을 참조로 설명하였다. 여기서, 본 명세서 및 청구범위에 사용된 용어나 단어는 통상적이거나 사전적인 의미로 한정해서 해석되어서는 아니되며, 본 고안의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다. 따라서, 본 명세서에 기재된 실시예와 도면에 도시된 구성은 본 고안의 가장 바람직한 일 실시예에 불과할 뿐이고 본 고안의 기술적 사상을 모두 대변하는 것은 아니므로, 본 출원시점에 있어서 이들을 대체할 수 있는 다양한 균등물과 변형예들이 있을 수 있음을 이해하여야 한다.In the above, preferred embodiments of the present invention have been described with reference to the accompanying drawings. Here, the terms or words used in the present specification and claims should not be construed as being limited to ordinary or dictionary meanings, but should be construed as meanings and concepts corresponding to the technical spirit of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical ideas of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

상술한 바와 같이 본 고안에 따른 누수감지케이블은 신호선과 감지선이 상호 나선형으로 꼬인 구조로 집합되므로 케이블의 단위길이당 누수감지능이 종래에 비해 향상되는 효과가 있다As described above, since the leak detection cable according to the present invention is assembled in a structure in which signal lines and detection lines are twisted in a spiral structure, the leak detection performance per unit length of the cable is improved compared with the conventional art.

또한, 본 고안은 별도의 외부시스가 피복되지 않더라도 꼬인 구조를 통해 자체적으로 집합상태를 유지할 수 있으므로 흡습성이 향상되는 잇점이 있다.In addition, the present invention has the advantage that the hygroscopicity is improved because it can maintain itself in the aggregate state through the twisted structure even if a separate outer sheath is not covered.

이러한 본 고안을 각종 시설물의 누수나 누유 등을 감지하는 선형센서로 사용할 경우 케이블의 직경을 크게 하거나, 길이를 무모하게 증대시키지 않더라도 누수감지효율을 높일 수 있어 동일효율 대비 케이블의 전체 부피가 감소하므로 취급이 용이한 장점이 있다.When the present invention is used as a linear sensor for detecting leakage or leakage of various facilities, the leakage detection efficiency can be increased without increasing the diameter of the cable or recklessly increasing the length, thereby reducing the overall volume of the cable compared to the same efficiency. It has the advantage of easy handling.
