Description

전력케이블의 접지선 취부구조{Fixing structure of ground wire of electric energy cable}Fixing structure of ground wire of electric energy cable}

본 발명은 전력케이블의 접지선 취부구조에 관한 것이다.The present invention relates to a ground wire mounting structure of a power cable.

최근 산업경제 및 국민생활의 급격한 성장으로 전력수요는 해마다 증가하고 있으며 인구 지중현상에 따른 대도시의 전력수요가 급격히 높아짐에 따라 기존의 가공송전선로에 의해 전력을 공급하던 방식에서 도시환경과 미관을 조화롭게 이룰 수 있는 방식의 지중송전선이 확대되고 있는 실정이다.With the recent rapid growth of industrial economy and people's life, electric power demand is increasing year by year. As the electric power demand of big cities due to population underground phenomenon is rapidly increasing, the existing environment and aesthetics are harmonized in the way that power was supplied by conventional overhead transmission lines. Underground transmission lines in a way that can be achieved is expanding.

일반적으로 지중송전선로를 이용하여 장거리에 전력전송을 하기 위해서는 케이블 시스를 일정구간마다 절단하여 분리하지 않으면 도체전류에 의한 유기전압이 상시 유기되어 선로 전체에 걸쳐 시스전류가 증대되어 자칫 점검원의 감전사고나 케이블 열화 및 설비고장의 원인이 되며, 과다하게 발생된 시스 순환전류는 전력전송측면에서 송전용량을 저하시키는 원인이 된다.In general, in order to transmit power over a long distance by using underground transmission lines, if the cable sheath is not cut and disconnected at regular intervals, the induced voltage caused by the conductor current is always induced, and the sheath current increases throughout the entire line. It may cause deterioration of cable and equipment failure, and excessively generated sheath circulating current may cause a decrease in transmission capacity in terms of power transmission.

이를 위해 양단 접지, 편단 접지, 직접 접지 및 크로스본드 접지방식 등에 의한 접지방식을 다양하게 조합하여 케이블의 일정구간마다 사용함으로써 시스 유 기전압을 감소시키고 있다. To this end, sheath organic voltage is reduced by using various combinations of grounding methods such as double-sided ground, one-sided ground, direct ground, and cross-bond grounding methods for every certain section of cable.

특히, 시스 접지방식 중 각 상의 시스를 일정 구간마다 연가한 후 접지하는 크로스본드 접지방식은 시스전압을 낮추고 시스전류에 의한 손실을 감소시키며 고장시의 고장전류의 귀환 경로를 제공할 뿐만 아니라 단락시 단락전류에 의해 유기되는 과전압을 효과적으로 차폐할 수 있어 장거리 선로에 가장 많이 채용되고 있다.Particularly, the cross-bond grounding method of connecting and grounding the sheath of each phase of the sheath grounding method by a certain section lowers the sheath voltage, reduces the loss caused by the sheath current, and provides a return path of the fault current in case of a fault, as well as a short circuit. Since the overvoltage induced by the short-circuit current can be effectively shielded, it is most widely used for long distance lines.

이와 같은 종래기술은 전력케이블의 접속개소에서의 전력케이블 및 접지선과 크로스본드선(이하, 접지선으로 통일하여 설명하도록 함.)의 설치를 위해 도 1, 도 2에서 도시되는 바와 같은 취부구조가 사용된다.Such a prior art uses a mounting structure as shown in Figs. 1 and 2 for the installation of a power cable and a ground wire and a cross bond wire (hereinafter, referred to as a ground wire) at the connection point of the power cable. do.

상기 벽체(110)는 맨홀 또는 전력구 내부를 도시한 것으로서, 콘크리트 구조물로 이루질 수 있다. 그리고, 상기한 벽체(130)에는 앵글 서포트(120)를 수직방향으로 설치하게 되는데, 상기 앵글 서포트(120)는 콘크리트 양생과정에서 설치되도록 할 수도 있고, 앵커볼트 등을 이용한 고정 작업도 가능하다.The wall 110 is shown as a manhole or a power sphere, it may be made of a concrete structure. In addition, the angle support 120 is installed in the vertical direction on the wall 130. The angle support 120 may be installed in a concrete curing process, or fixing work using an anchor bolt or the like.

여기서, 상기 앵글서포트(120)의 수직방향으로 다수의 체결홀(121)이 형성되는 것이 바람직하다. 상기 체결홀(121)은 앵글 서포트(120) 상에 행거(130) 및 지지금구(170)를 결합하도록 하는데, 수직방향으로 다수가 소정간격 이격된 상태로 형성되고 있어, 행거(130) 및 지지금구(170)의 결합 위치를 조정할 수 있게 된다.Here, it is preferable that a plurality of fastening holes 121 are formed in the vertical direction of the angle support 120. The fastening hole 121 is to be coupled to the hanger 130 and the support sphere 170 on the angle support 120, the plurality is formed in a vertically spaced apart state in the vertical direction, hanger 130 and support The engagement position of the bracket 170 can be adjusted.

그리고, 상기 행거(130)는 일단에 앵글서포트(120)에 대해 착탈결합이 가능하도록 다수의 체결홀(131)이 형성되는 것이 바람직하다.In addition, the hanger 130 is preferably formed with a plurality of fastening holes 131 to be detachably coupled to the angle support 120 at one end.

이때, 상기 행거(130)의 일단은 "T"자형 연결부로 형성될 수 있고, 볼트와 같은 체결부재(180)를 이용해 체결되도록 할 수 있다.At this time, one end of the hanger 130 may be formed as a "T" shaped connection, it can be fastened using a fastening member 180 such as a bolt.

상기한 지지금구(170)는 한 가닥의 접지선(160)을 취부하는 구조가 도3, 도4 를 통해 도시되고 있으나, 다수의 접지선(160)을 동시에 취부하는 구조도 가능하다. 이경우, 취부홈(173)의 형성 개수를 다수로 형성할 수 있다.Although the structure for attaching the support wire 170 is illustrated in FIGS. 3 and 4, the support bracket 170 may also have a structure for simultaneously mounting a plurality of ground wires 160. In this case, a large number of forming grooves 173 may be formed.

상기한 구성에 따른 본 발명은 케이블(150)의 상부 일측 앵글서포트(120)에 지지금구(170)의 일단이 결합되며, 상기 지지금구(170) 상부에 접지선(160)이 취부되도록 함으로써, 전력케이블(150)이 열신축에 의해 수평방향의 유동이 발생할 때, 접지선(160)이 파손되는 것을 방지할 수 있게 된다.According to the present invention according to the above configuration, one end of the support hole 170 is coupled to the upper one side angle support 120 of the cable 150, and the ground wire 160 is mounted on the support hole 170, thereby providing power. When the cable 150 has a horizontal flow due to thermal expansion and contraction, it is possible to prevent the ground wire 160 from being damaged.

또한, 이로 인한 전력손실을 방지할 수 있고, 크로스본드 본래의 기능에 충실할 수 있게 된다.In addition, power loss caused by this can be prevented and the original function of the crossbond can be faithful.

그리고, 본 발명은 접지선(160)이 전력케이블(150)의 상측에 거치됨으로써, 접지선(160)의 파손여부를 육안으로는 쉽게 점검할 수 있고, 정비하거나 보수작업이 간편해지게 된다.In addition, in the present invention, since the ground wire 160 is mounted on the upper side of the power cable 150, whether the ground wire 160 is broken can be easily visually checked, and maintenance or maintenance work becomes simple.

또한, 접지선(160)의 처짐을 예방하는 동시에 안전한 취부가 가능하고, 시공의 균일성을 확보하게 되는 것은 물론, 미려한 시공이 가능한 이점을 갖게 된다.In addition, it is possible to prevent sagging of the ground wire 160 and at the same time to secure the installation, to ensure the uniformity of construction, as well as to have a beautiful construction.
