본 고안은 고압선로에 사용되는 케이블의 접속재에 관한 것으로써, 특히 다층의 피복을 갖는 케이블을 상호 접속하는 접속슬리브의 사용 융통성이 크고, 접속부위의 전기적인 안정성이 보장될수 있도록 이루어진 접속재에 관한 것이다.The present invention relates to a connection member of a cable used in a high-voltage line, and more particularly to a connection member made of a flexible use of the connection sleeve for interconnecting a cable having a multi-layer sheath, and to ensure the electrical stability of the connection portion .
통상 수십킬로볼트(KV)의 고압선로용 급전선으로 사용되는 케이블은 전기적인 절연및 전압의 균등분포와 차폐를 목적으로 절연재및 반도전재의 수지로 피복제조되는 것으로 알려져 있다.Cables commonly used as feed lines for high-voltage lines of several tens of kilovolts (KV) are known to be coated with resins of insulating and semiconducting materials for the purpose of electrical insulation and equal distribution of voltage and shielding.
상기 케이블은 경우에 따라서 분기 또는 직선접속되어 전로를 이루게 되는바, 대부분의 케이블 사고는 주로 접속부위에서 발생되는 것이어서 접속재를 보다 완벽하게 구현하는 것이 요구된다.In some cases, the cable is branched or connected in a straight line to form a converter, and most cable accidents are mainly generated at the connection part, and thus, it is required to implement the connection material more completely.
상기 접속재에 있어서, 종래의 직선접속재를 살펴보면 다음과 같다.In the connecting member, the conventional straight connecting member is as follows.
제4도에 도시된 바와같은 종래기술에 의하면 중앙부가 양단부에 비하여 굵은 원통체로 이루어져 외부반도전층(1), 절연재(2)및 내부반도전층(3)의 다층구조를 이루되 중심관통공(4)과 이 관통공(4)의 중앙부에 접속슬리브가 위치되는 확개공(5)이 천공되고, 상기 확개공(5)내의 슬리브(7)와 압지하기위한 요입부(6)를 포함하여 단면형상이 클로버 형상을 갖도록 이루어지는 것이다.According to the prior art as shown in FIG. 4, the central portion has a thicker cylindrical body than both ends thereof, and forms a multilayer structure of the outer semiconducting layer 1, the insulating material 2, and the inner semiconducting layer 3, but has a central through-hole. ) And an expansion hole 5 in which the connecting sleeve is located at the center of the through hole 4, and includes a sleeve 7 in the expansion hole 5 and a concave inlet portion 6 for pressing. It is made to have a clover shape.
상기와 같은 종래접속재는 케이블과 케이블이 상호 접속슬리브(7)로써 압착되어져 상기 접속재내로 인입설치됨에 있어서 케이블의 나선부분이 내부반도전층(3)과 긴밀하게 접속되는 상태가 유지되어야 하나 내부반도전층(3)의 요입부(6)는 길이방향으로 선접촉을 이루는 구조를 갖게되어 고른 접촉유지가 곤란하여 접속슬리브(7)부근의 전압의 불균일한 분포를 초래하는 문제가 있으며, 또한 접속슬리브(7)의 압착작업시의 압착정도에 따라서 슬리브외경이 변화하므로, 슬리브 외경이 크게된 때에는 내부 반도전층(3)과의 접촉력은 향상될 수 있으나 접속부인 슬리브(7)를 확개공(5)내로 인입하는데 곤란한 문제가 유발되고, 반대로 슬리브(7)압착강도가 높아 슬리브 외경이 작아진 경우에는 슬리브 유입은 용이하나 내부반도전층(3)과의 접촉이 고르지 못한 단점을 갖으며 슬리브(7)의 외경수치가 조금 상이한 경우에는 사용이 불가한 제한성을 갖는 것이다.In the conventional connection material as described above, the cable and the cable are crimped with the interconnect sleeve 7 so that the spiral portion of the cable is kept in close contact with the internal semiconductor layer 3 while being inserted into the connection material. The concave portion 6 of (3) has a structure in which line contact is made in the longitudinal direction, which makes it difficult to maintain even contact, resulting in a non-uniform distribution of the voltage near the connection sleeve (7). Since the outer diameter of the sleeve changes according to the degree of crimping during the crimping operation of 7), the contact force with the inner semiconducting layer 3 can be improved when the outer diameter of the sleeve is increased, but the sleeve 7, which is a connecting portion, is introduced into the opening 5. The problem of difficulty in pulling is caused, and on the contrary, when the sleeve 7 has a high compressive strength and the sleeve outer diameter is reduced, the sleeve is easily introduced, but the contact with the inner semiconducting layer 3 is uneven. If it has had the disadvantage that the outer diameter value of the sleeve (7) has a bit different to have a limitation, and use is allowed.
따라서 본 고안은 상술된 바와같은 종래기술이 갖는 제문제점을 해소하고자 안출된 것으로써 고압선로용 케이블 접속재의 내부도전층과 슬리브 접촉구조를 면접촉되도록 이루어 개복된 케이블 접속부위의 접촉력을 향상시켜 전압분포를 균일하게 하며 슬리브의 외경이 상당히 변화하더라도 수용가능하도록된 직선접속재를 제공하는 것을 목적으로 한다.Therefore, the present invention is designed to solve the problems of the prior art as described above, so that the inner conductive layer and the sleeve contact structure of the cable connection member for the high voltage line are brought into surface contact, thereby improving the contact force of the opened cable connection part. It is an object of the present invention to provide a straight connecting material which is uniform in the distribution and made to be acceptable even if the outer diameter of the sleeve changes considerably.
상기 목적을 구현하고자 이루어지는 본 고안은 접속슬리브가 위치하게될 내부반도전층의 접촉구조를 그 단면상 대략균등분할하여 내향절개된 탄성부로 이루어지는 것이다.The present invention made to achieve the above object is made of an elastic part which is cut inwardly by roughly evenly dividing the contact structure of the inner semiconducting layer on which the connection sleeve is located.
이하, 첨부도면을 참조하여 본 고안의 기술구성을 상세하게 살펴보기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail the technical configuration of the present invention.
제1도 내지 제2도에 있어서, 본 고안은 케이블을 상호직선 접속하기 위하여 중앙부가 양단부에 비하여 굵은 원통체로 이루어지고, 외부반도전층(1), 절연재(2) 및 내부반도전층(3)의 다층구조로 이루며 중심을 관통하는 관통공(4)과 이 관통공(4)의 중앙부에 확개공(5)이 마련된 직선접속재에 있어서, 상기 내부반도전층(3)으로 이루어지는 확개공(5)은 상기 내부반도전층(3)으로 부터 중심부로 대략 등각분할되고 내향절개된 탄성부(8)를 연설하되 복수로 형성하여 고압선로용 케이블의 직선접속재를 이루는 것이다. 여기서 종래의 기술구성에 대응하는 부분은 동일한 부호를 사용하여 설명하였다.In FIGS. 1 to 2, the present invention is made of a cylindrical body having a thicker center portion at both ends in order to connect the cables to each other in a straight line, and the outer semiconducting layer 1, the insulating material 2, and the inner semiconducting layer 3 of FIG. In the linear connection material having a multi-layered structure and having a through hole (4) penetrating the center and an extension hole (5) in the center of the through hole (4), the extension hole (5) consisting of the inner semiconducting layer (3) From the inner semiconducting layer (3) to the center is roughly isotropically divided and inwardly cut the elastic portion 8 to form a plurality to form a straight connection of the cable for high-voltage lines. Here, the parts corresponding to the conventional technical configuration have been described using the same reference numerals.
상술된 바와같은 기술구성을 이루는 본 고안은 다음과 같은 효과를 갖는다.The present invention constituting the technical configuration as described above has the following effects.
본 고안은 케이블과 케이블을 상호 직선접속함에 있어서 본 고안의 접속재 외측에서 통상의 접속슬리브(7)로써 압착하여 접속을 행한뒤 접속재의 관통공(4)을 통하여 상기 슬리브(7)가 확개공(5)내에 위치하도록 할때 제3도에 도시된 바와같이 확개공(5)에 연설된 탄성부(8)는 상기 슬리브(7)에 밀려 일측으로 휨이 발생하고 따라서 상기 케이블의 개복부위에 위치하는 슬리브(7)는 긴밀하게 내부 반도전층(3)과 면접촉되게 되며 이때 슬리브(7)의 직경이 작업시 압착강도에 따라 다소 상이 하더라도 상기 탄성부(8)에 의하여 융통성이 있게 수용될수 있는 효과를 갖는 것이다.According to the present invention, when the cable and the cable are connected to each other in a straight line, the sleeve 7 is compressed through the through hole 4 of the connecting material after being crimped and connected by a normal connecting sleeve 7 from the outside of the connecting material of the present invention. 5) When it is located in the inside, as shown in FIG. 3, the elastic part 8, which is extended to the extension hole 5, is pushed by the sleeve 7 so that bending occurs to one side and thus is located at the open part of the cable. The sleeve 7 is in intimate contact with the inner semiconducting layer 3, wherein the sleeve 7 can be flexibly accommodated by the elastic part 8 even if the diameter of the sleeve 7 is slightly different depending on the compressive strength during operation. It has an effect.
또한 슬리브(7)직경 및 길이가 다소 상이한 부품일지라도 수용이 가능하며 상기 탄성부(8)에 의하여 면접촉되는 슬리브는 내부반도전층 고유의 기능을 발휘함에 있어 고른 전계분포를 유도할수 있는 효과를 갖는다. 물론 여기서 상기 탄성부(8)는 필요에 따라서 다수로 균등분할을 하여 절개 형성할 수 있는바, 접촉강도와 작업성을 모두 만족하기 위하여 대략3절하여 형성함이 바람직 하다 할 것이다.In addition, the sleeve 7 can be accommodated even if the parts are slightly different in diameter and length, and the sleeve that is in surface contact by the elastic part 8 has an effect of inducing an even electric field distribution in the intrinsic function of the internal semiconductor layer. . Of course, the elastic portion 8 may be formed by cutting a plurality of evenly divided as necessary, it will be preferable to form approximately three to meet both contact strength and workability.
이상에서 살펴본 바와같은 본 고안은 접속재의 내부도전층과 슬리브를 면접촉하게 이루어 종래 선접촉형태에 비하여 접촉이 정확하고 긴밀하게 이루어져 균등한 전압분포를 갖게되고 슬리브의 외경이 변화하더라도 수용가능한 효과를 갖는 매우 실용적인 고안인 것이다.As described above, the present design makes the inner conductive layer of the connecting material and the sleeve in surface contact so that the contact is more accurate and tighter than the conventional line contact type, so that the contact has an even voltage distribution and has an acceptable effect even if the outer diameter of the sleeve changes. It is a very practical design.
