Description

FRP를 사용한 초고압 케이블의 케이블 접속함{High voltage cable connecting housing by using FRP}High voltage cable connecting housing by using FRP}

본 고안은 초고압 케이블의 케이블 접속함 구조에 관한 것으로서, 특히 초고압 전선의 접속함의 외부 구조를 FRP 를 사용하여 형성하여 접속함의 제조를 용이하게 하고 전기적 절연 성능을 일정하게 유지하도록 하는 FRP를 사용한 초고압 케이블의 케이블 접속함에 관한 것이다.The present invention relates to the cable junction box structure of the ultra-high voltage cable, in particular, to form the outer structure of the junction box of the ultra-high voltage wire by using the FRP ultra-high voltage cable using the FRP to facilitate the manufacture of the junction box and to maintain a constant electrical insulation performance Of the cable connection box.

초고압의 전압을 갖는 전원을 송전하기 위해 사용하는 송전 케이블은 전체 송케이블이 하나의 케이블으로 이루어지는 것이 가장 이상적이나, 케이블은 일정한 길이를 갖고 있어 현실적으로 불가능하다. 따라서, 긴 송전선로를 제작하기 위해서는 일정 길이의 케이블을 연결하여 서로 연결하여야 하고 이때, 케이블과 케이블을 연결하기 위해 접속함을 사용하게 된다.The transmission cable used to transmit a power supply having an ultra high voltage is most ideally composed of one cable as a whole, but the cable has a certain length and is practically impossible. Therefore, in order to manufacture a long transmission line should be connected to each other by connecting a certain length of cable, in this case, the connection box is used to connect the cable and the cable.

이때 사용하는 접속함의 구조가 도 1에 도시되어 있다. 도 1은 일반적인 접속함의 일실시예의 형태를 나타내는 부분 단면도로서, 도면을 참조하여 그 구조를 살펴보면 다음과 같다.The structure of the junction box used at this time is shown in FIG. 1 is a partial cross-sectional view showing a form of an embodiment of a general junction box, referring to the structure as follows.

에폭시 재질로 제조된 원뿔형 접속부(2)에 원통형으로 형성된 외부함(3)을 연결한 후, 외부함(3)의 중심축상에 형성된 형성된 홀을 통해 케이블(1)을 삽입시켜 접속부(2)까지 케이블(1)이 통과되도록 한다. 케이블(1)이 접속부(2)를 통과되도록 한 후, 케이블(1)이 삽입되어 있는 접속부(2)를 전원이 필요한 곳에 밀착시켜 접합시키게 되면, 외부에서 공급되는 전원이 케이블(1)을 통해 흐르게 된다.After connecting the outer box 3 formed in a cylindrical shape to the conical connection part 2 made of epoxy material, the cable 1 is inserted through the formed hole formed on the center axis of the outer box 3 to the connection part 2. Allow the cable (1) to pass through. After allowing the cable 1 to pass through the connection part 2, and when the connection part 2 into which the cable 1 is inserted is brought into close contact with a place where power is required, externally supplied power is supplied through the cable 1. Will flow.

이때 외부함(3)의 측면에는 접지 단자(3)가 부착되어 있어 누설 전류가 발생할 경우 발생된 누설 전류가 접지되도록 한다.At this time, the ground terminal 3 is attached to the side of the outer box 3 so that the leakage current generated when the leakage current occurs is grounded.

또한, 접속부(2)의 내부에 삽입된 케이블이 일정 위치에 머물도록 하는 보호 밀대(6)도 에폭시 재질로 제조된다.In addition, the protective rod 6 for allowing the cable inserted in the connection portion 2 to stay at a predetermined position is also made of epoxy material.

상기한 구조의 접속함은 접속부(2)와 외부함(3)이 연결되어 형성됨을 알 수 있다. 외부함(3)은 케이블(1)과 케이블 접속부(2)을 기계적으로 보호하는 역할을 하게 되고, 상기 외부함은 주로 동 또는 스테인레스 스틸과 같은 재질로 만들어지게 된다.It can be seen that the junction box of the above structure is formed by connecting the connection portion 2 and the outer box (3). The outer box 3 serves to mechanically protect the cable 1 and the cable connecting part 2, and the outer box is mainly made of a material such as copper or stainless steel.

외부함이 금속 재질로 만들어지기 때문에 제조 비용이 높고, 전기적 절연성을 유지하기 위해 외부함의 외부에 절연구조물을 추가로 형성해야만 하는 문제점이 있었다.Since the outer box is made of a metal material, there is a problem in that manufacturing cost is high and an insulation structure must be additionally formed on the outside of the outer box in order to maintain electrical insulation.

본 고안은 상기한 문제점을 해결하기 위해 안출된 것으로서, 케이블 접속함을 형성하는 외부함을 금속 재질이 아닌 FRP를 이용하여 제조함으로서 제조 비용과 제작 시간을 대폭 단축시킬 수 있고 절연 성능을 갖도록 하는 FRP를 사용한 초고압 케이블의 케이블 접속함을 제공하는 것을 목적으로 한다.The present invention has been made to solve the above problems, by manufacturing the outer box to form a cable junction box using a non-metallic FRP can significantly reduce the manufacturing cost and manufacturing time and has an FRP to have insulation performance It is an object of the present invention to provide a cable junction box of an ultra-high voltage cable.

본 고안에 따른 목적을 달성하기 위해 본 고안 FRP 재질의 접속함 구조는, 고전압 케이블의 케이블 접속함에 있어서, 케이블 접속함을 형성하는 외부함을 FRP 재질로 제작하고 케이블 차폐층에 접지 단자가 연결되도록 구성되는 것을 특징으로 한다.In order to achieve the object according to the present invention, the junction box structure of the FRP material of the present invention, in the cable connection of the high-voltage cable, the outer box forming the cable junction box is made of FRP material so that the ground terminal is connected to the cable shielding layer It is characterized in that the configuration.

도 1은 일반적인 접속함의 일실시예의 형태를 나타내는 부분 단면도.1 is a partial cross-sectional view showing the form of one embodiment of a general junction box.

도 2는 본 고안에 따른 FRP 재질의 접속함 구조의 일실시예를 나타내는 부분 단면도.Figure 2 is a partial cross-sectional view showing an embodiment of the junction box structure of the FRP material according to the present invention.

20 : 외부함 30 : 접지단20: outer box 30: ground terminal

도 2는 본 고안에 따른 FRP 재질의 접속함 구조의 일실시예를 나타내는 부분 단면도로서, 접속부(10)와 외부함(20)이 서로 연결되어 있고, 접속부(10)와 외부함(20)의 중심부측에 케이블(1)이 삽입 고정되어 있는 것은 종래의 기술과 동일하다.2 is a partial cross-sectional view showing an embodiment of the junction box structure of the FRP material according to the present invention, the connection portion 10 and the outer box 20 is connected to each other, the connection portion 10 and the outer box 20 It is the same as that of the prior art that the cable 1 is inserted and fixed to the center part side.

이때 외부함(20)은 FRP(Fiber reinforcement plastic) 재질로 제조되도록 하여 추가의 절연 구조를 채택하지 않아도 절연 성능을 얻을 수 있도록 한다. 외부함(20)이 FRP 재질로 되어 있기 때문에 접지 단자(30)는 케이블(1)의 도전층을 둘러싸고 있는 차폐층에 설치하여 케이블(1)에서 누설 전류가 발생할 경우 접지되도록 한다.In this case, the outer box 20 is made of FRP (Fiber reinforcement plastic) material so as to obtain insulation performance without adopting an additional insulation structure. Since the outer box 20 is made of FRP material, the ground terminal 30 is installed in a shielding layer surrounding the conductive layer of the cable 1 to be grounded when a leakage current occurs in the cable 1.

외부함(20)의 재질이 FRP 이기 때문에 자체적으로 절연 성능을 갖게 되어 별도의 보호함을 설치할 필요가 없게 된다.Since the material of the outer box 20 is FRP, it has insulation performance on its own, so that there is no need to install a separate protective box.

상기한 바와 같이 구성된 본 고안은 고전압 케이블을 서로 연결하기 위해 사용하는 전선 접속함의 외부함을 기존의 동 또는 스테인레스 스틸 재질로 제조하지 않고 FRP 재질을 사용하여 제작함으로서 외부와의 전기적 절연을 위해 추가의 절연구조를 형성시킬 필요가 없게 된다.The present invention configured as described above is manufactured by using the FRP material instead of the existing copper or stainless steel material of the wire junction box used to connect the high voltage cables to each other. There is no need to form an insulating structure.
