본 발명은 송배전 고압 케이블 관로내 인입장치에 관한 것으로, 더욱 상세하게는 당김 와이어와 고압 케이블이 서로 꼬이지 않도록 연결되어 고압 케이블의 인입이 자유롭고, 고압 케이블의 이탈과 손상을 방지할 수 있는 송배전 고압 케이블 관로내 인입장치에 관한 것이다.The present invention relates to an apparatus for injecting and distributing a high voltage cable in a pipeline, and more particularly, a wire and a high voltage cable are connected so that the pull wire and the high voltage cable are not twisted with each other to freely pull in the high voltage cable, and the transmission and distribution high voltage cable which can prevent the high voltage cable from being separated and damaged. It relates to an in-pipe drawing device.

발전소에서 발전된 전력은 송전선과 변전소를 거쳐서 공급된 후, 최종적인 수용가 또는 전력사용시설로 공급되기 위해 이들 수용가나 전력사용시설에 근접 설치된 수변전설비를 거치게 된다. The power generated by the power plant is supplied through transmission lines and substations, and then through the water substations installed in close proximity to these consumers or facilities to be supplied to the final customers or facilities.

이러한 수변전설비는 도로변에 설치되는 지상기기와 전주를 통해 제공된다. These water substation facilities are provided through ground equipment and poles installed on the roadside.

구체적으로 설명하면, 변전소의 지중 고압 케이블은 지중에서 지상으로 인출되어 전주에 고정되고, 고압 케이블 내의 3상 케이블은 수용측 3상 수변전 케이블과 커넥터를 통해 연결된다.Specifically, the underground high voltage cable of the substation is drawn out from the ground to the ground and fixed to the pole, and the three-phase cable in the high voltage cable is connected through the receiving side three-phase water substation cable and the connector.

한편 수변전설비에서 고압 케이블이 각 수용측으로 배선될 때 건축물의 벽을 관통하기도 한다.On the other hand, when the high voltage cable is routed to each receiving side in the water substation facility, it may penetrate the walls of the building.

이와 같이 고압 케이블이 건축물의 벽을 관통하여 배선될 때 케이블관(보호관)이 사용되고 있다. 즉, 건축물의 벽에 케이블관을 삽입(매설)하고, 상기 케이블관 내부에 고압 케이블을 배선하는 것이다.In this way, a cable tube (protective tube) is used when a high voltage cable is wired through a wall of a building. That is, a cable tube is inserted (embedded) in the wall of the building, and a high voltage cable is wired inside the cable tube.

그리고, 이와 같은 종래 구성의 케이블관 내에 케이블을 인입하는 경우에는, 당김 와이어를 케이블관의 타측에서 일측으로 관통시키고 이 당김 와이어의 단부에 고압 케이블을 매듭 연결하여 일측에서부터 타측으로 잡아당김으로써 상기 고압 케 이블을 상기 케이블관에 배선하는 것이다.And, when the cable is introduced into the cable tube of such a conventional configuration, the high-pressure cable by passing the pull wire from one side to the other side of the cable tube and connecting a high-voltage cable to the end of the pull wire and pulling it from one side to the other side. The cable is routed to the cable conduit.

그러나 종래 기술에 의한 고압 케이블 인입방법에 따르면, 고압 케이블을 단순하게 매듭 연결한 것이기 때문에 고압 케이블과 당김 와이어의 연결 및 해체 작업이 번거롭고, 당김 와이어를 잡아당길 때 당김 와이어가 꼬일 수 있는데, 당김 와이어와 고압 케이블의 연결 구조상 당김 와이어와 함께 고압 케이블이 꼬이며, 매듭이 풀려 고압 케이블이 당김 와이어에서 이탈되는 문제점이 있다.However, according to the conventional high-voltage cable entry method, since the high-voltage cable is simply knotted, the connection and dismantling of the high-voltage cable and the pulling wire is cumbersome, and when the pulling wire is pulled, the pulling wire may be twisted. Due to the connection structure of the high-voltage cable and the high-voltage cable is twisted with the pull wire, there is a problem that the high-voltage cable is separated from the pull wire by loosening the knot.

그리고, 당김 와이어를 잡아당겨 고압 케이블을 인입할 때 고압 케이블이 케이블관의 내주면과 마찰되기 때문에 마찰에 의해 고압 케이블의 피복이 손상되는 문제점도 있다.In addition, since the high voltage cable is rubbed with the inner circumferential surface of the cable tube when the high voltage cable is pulled in by pulling the pulling wire, there is a problem that the coating of the high pressure cable is damaged by the friction.

본 발명은 상기한 종래 문제점을 해결하기 위한 것으로, 송배전 고압 케이블을 건축물의 일측에서 타측으로 잡아당겨 배선할 때 당김 와이어와 고압 케이블의 결속력을 증대하여 고압 케이블의 이탈을 막고 고압 케이블이 꼬이지 않도록 한 송배전 고압 케이블 관로내 인입장치를 제공하려는데 그 목적이 있다.The present invention is to solve the above-mentioned conventional problems, to increase the binding force of the pull wire and the high-voltage cable when wiring the transmission and distribution high-voltage cable from one side of the building to the other side to prevent the separation of the high-voltage cable and to prevent the high-voltage cable from twisting. It is an object of the present invention to provide an apparatus for in-transmission high voltage cable pipeline entry.

그리고, 본 발명의 다른 목적은 고압 케이블이 케이블관을 통과할 때 고압 케이블과 케이블관의 마찰을 없애려는데 있다.Another object of the present invention is to eliminate the friction between the high pressure cable and the cable tube when the high pressure cable passes through the cable tube.

상기 목적을 달성하기 위한 본 발명에 따른 송배전 고압 케이블 관로내 인입 장치는, 건축물의 벽에 관통 매설된 케이블관 내부에 삽입되는 당김 와이어의 일측에 연결되는 베어링수단, 상기 베어링수단에 제자리 회전 가능하게 연결되며 고압 케이블이 삽입 및 조여 고정되는 케이블 결속구를 포함하여 구성된 것을 특징으로 한다.The transmission and distribution high-voltage cable in-line drawing device according to the present invention for achieving the above object, the bearing means connected to one side of the pull wire is inserted into the cable pipe embedded in the wall of the building, rotatably in the bearing means It is characterized in that it comprises a cable ties that are connected and the high-voltage cable is inserted and tightened.

본 발명의 특징 및 이점들은 첨부도면에 의거한 다음의 상세한 설명으로 더욱 명백해질 것이다. 이에 앞서, 본 명세서 및 청구범위에 사용된 용어나 단어는 발명자가 그 자신의 발명을 가장 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 입각하여 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다.The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.

It must be interpreted to mean meanings and concepts.

도 1 내지 도 3에서 보이는 것처럼, 본 발명에 의한 송배전 고압 케이블 관로내 인입장치는, 당김 와이어(1)에 연결되는 베어링수단(100)과, 베어링수단(100)의 후방에 결합되며 고압 케이블(2)을 고정하는 케이블 결속구(200)를 포함하여 고압 케이블(2)을 케이블 결속구(200)에 고정하고 당김 와이어(1)를 베어링수단(100)에 연결한 상태에서 당김 케이블(1)을 케이블관(3)에 삽입하여 일측에서부터 타측으로 잡아 당김으로써 고압 케이블(2)을 케이블관(3) 내부에 인입하도록 구성되며, 이하 각 구성요소를 구체적으로 설명한다.As shown in Figures 1 to 3, the transmission and distribution high-voltage cable in the pipeline device according to the present invention, the bearing means 100 is connected to the pulling wire (1), coupled to the rear of the bearing means 100 and the high pressure cable ( 2) Including the cable fastener 200 for fixing the high-voltage cable (2) to the cable fastener 200 and the pull wire (1) in the state connected to the bearing means 100 pull cable (1) By inserting into the cable pipe 3 and pulling from one side to the other side is configured to lead the high voltage cable 2 into the cable pipe 3, each component will be described in detail below.

도 1에서처럼 베어링수단(100)은 내부에 중공부가 형성되며 길이방향 양측에 각각 통공(111,112)이 구비된 하우징(110), 하우징(110) 양측 통공(111,112)을 통해 삽입되면서 와셔(121,131)를 매개로 하여 각각 하우징(110) 내부에 제자리 회전 가능하도록 지지되는 제1,2회전 앵커(120,130)로 구성된다. 즉, 고압 케이블(2)의 인입 과정 중 당김 와이어(1) 또는 고압 케이블(2)이 회전하더라도 베어링수단(100)에 의해 당김 와이어(1)와 고압 케이블(2)이 꼬이지 않게 된다.As shown in FIG. 1, the bearing means 100 has a hollow formed therein, and the washers 121 and 131 are inserted through the housing 110 having the through holes 111 and 112 at both sides thereof in the longitudinal direction, and the through holes 111 and 112 at both sides of the housing 110. The first and second rotation anchors 120 and 130 are rotatably supported in the housing 110 to rotate in place. That is, even when the pull wire 1 or the high pressure cable 2 rotates during the drawing of the high voltage cable 2, the pull wire 1 and the high pressure cable 2 are not twisted by the bearing means 100.

제1,2회전 앵커(120,130)는 그 단부 외주면에 나사선이 형성되어 와셔(121,131)에 관통된 후 너트(122,132)가 체결되어 하우징(110)에서 이탈되지 않는다.The first and second rotary anchors 120 and 130 have a thread formed on the outer circumferential surface of the end thereof, and penetrate through the washers 121 and 131, so that the nuts 122 and 132 are fastened so as not to be separated from the housing 110.

하우징(110)은 내부에 와셔(121,131)와 너트(122,132)가 삽입될 수 있도록 각각 반원형 편이 결합되어 이루어지거나 길이방향 양측에 각각 캡이 결합되는 구조일 수 있다.The housing 110 may have a structure in which semicircular pieces are coupled to each other so that the washers 121 and 131 and the nuts 122 and 132 may be inserted therein, or the caps may be coupled to both sides in the longitudinal direction, respectively.

베어링수단(100)의 제1,2회전 앵커(120,130)는 당김 와이어(1)와 케이블 결속구(200)를 연결하는 매개물로서, 제1회전 앵커(120)는 두부 볼트 형태로 이루어져 두부측에 와이어 고리(123)가 구비되어 당김 와이어(1)와 연결되고, 제2회전 앵커(130)는 후술하는 케이블 홀더(210)에 지지된다.The first and second rotary anchors 120 and 130 of the bearing means 100 are mediators for connecting the pull wire 1 and the cable fastener 200, and the first rotary anchor 120 is formed in the form of a head bolt to the head side. The wire ring 123 is provided and connected to the pulling wire 1, and the second rotation anchor 130 is supported by the cable holder 210 to be described later.

케이블 결속구(200)는 내부에 일측이 개방된 케이블 삽입홈(211)이 구비되며 타측에 베어링수단(100)의 제2회전 앵커(130)가 연결되는 원통형 케이블 홀더(210), 각각 반원형 단면으로 형성되어 고압 케이블(2)을 감싸는 한 쌍의 커플링(220), 케이블 홀더(210)의 둘레부에 케이블 홀더(210)를 관통하도록 체결되어 커플링(220)을 통해 케이블 홀더(210)에 삽입된 고압 케이블(2)을 조여 고정하는 하나 이상의 조임구(230)로 이루어질 수 있다.The cable binding hole 200 is provided with a cable insertion groove 211 having one side open therein, and a cylindrical cable holder 210 having a second rotating anchor 130 of the bearing means 100 connected to the other side thereof, each having a semicircular cross section. A pair of couplings 220 formed around the high voltage cable 2 and fastened to penetrate the cable holder 210 at the periphery of the cable holder 210 are connected to the cable holder 210 through the coupling 220. It may be made of one or more fasteners 230 for tightening and fixing the high-voltage cable (2) inserted in the.

이와 같이 구성된 본 발명에 의한 송배전 고압 케이블 관로내 인입장치에 의한 인입방법은 다음과 같다.The draw-in method by the drawer in the transmission / distribution high-voltage cable pipeline according to the present invention configured as described above is as follows.

도 2와 도 3에서처럼, 고압 케이블(2)의 단부 외주부에 한 쌍의 커플링(220)을 덮고, 이어서, 고압 케이블(2)의 단부를 케이블 홀더(210)에 삽입하며, 이어서, 조임구(230)를 조여 케이블 홀더(210)에 고압 케이블(2)을 연결한다. 고압 케이블(2)은 커플링(220)에 의해 덮여 보호되어 조임구(230)의 조임시 단선 등이 발생되지 않으며 또한 커플링(220)과 면접촉되므로 조임구(230)와 고압 케이블(2)간의 결속력을 증대할 수 있다.2 and 3, a pair of couplings 220 are covered on the outer periphery of the end of the high voltage cable 2, and then the end of the high voltage cable 2 is inserted into the cable holder 210, and then the fasteners. Tighten the 230 to connect the high voltage cable (2) to the cable holder (210). The high voltage cable 2 is covered and protected by the coupling 220 so that disconnection does not occur when the tightening hole 230 is tightened, and the high pressure cable 2 is in surface contact with the coupling 220. You can increase the cohesion between).

이어서, 당김 와이어(1)의 일측 단부(케이블관(3)의 일측)를 와이어 고리(123)에 매듭한 후 당김 와이어(1)의 타측(케이블관(3)의 타측)을 잡아 당기면, 당김 와이어(1)를 통해 가해지는 힘에 의해 베어링수단(100)과 케이블 결속구(200)가 당김 와이어(1)와 함께 케이블관(3)의 일측에서 타측으로 인입되며 이로써 고압 케이블(2)이 케이블 결속구(200)와 함께 케이블관(3)에 서서히 인입된다.Subsequently, when one end (one side of the cable tube 3) of the pulling wire 1 is knotted to the wire loop 123, the other side (the other side of the cable tube 3) of the pulling wire 1 is pulled out, and the pulling is performed. The bearing means 100 and the cable engagement port 200 are pulled together from one side of the cable pipe 3 to the other side by the force applied through the wire 1, so that the high pressure cable 2 is pulled out. It gradually enters into the cable pipe 3 with the cable ties 200.

이와 같이 고압 케이블(2)이 인입될 때 당김 와이어(1)가 꼬일 수 있지만 고압 케이블(2)은 꼬이지 않고 인입될 수 있다. 왜냐하면 당김 와이어(1)가 꼬이게 되면 당김 와이어(1)와 함께 제1회전 앵커(120)만 하우징(110) 내부에서 돌아가게 되어 제2회전 앵커(130)에 연결된 케이블 결속구(200)는 돌아가지 않기 때문이다. 반대로 고압 케이블(2)이 꼬일 경우에도 당김 와이어(1)는 꼬임이 발생되지 않는다. In this way, the pull wire 1 may be twisted when the high voltage cable 2 is drawn in, but the high pressure cable 2 may be drawn without being twisted. Because when the pull wire 1 is twisted, only the first rotation anchor 120 together with the pull wire 1 rotates inside the housing 110, so that the cable tie 200 connected to the second rotation anchor 130 is turned back. Because I do not go. On the contrary, even when the high voltage cable 2 is twisted, the pulling wire 1 is not twisted.

고압 케이블(2)이 케이블관(3)을 관통하여 케이블관(3)의 타측으로 인출되면 조임구(230)를 풀어 고압 케이블(2)을 케이블 홀더(210)에서 분리한다. 이로써, 고압 케이블(2)의 인입을 완료한다.When the high pressure cable 2 passes through the cable tube 3 and is drawn out to the other side of the cable tube 3, the fastener 230 is released to separate the high voltage cable 2 from the cable holder 210. This completes the insertion of the high voltage cable 2.

도 4는 본 발명에 의한 송배전 고압 케이블 관로내 인입장치의 변형 예시도로서, 케이블 홀더(210)가 케이블관(3)의 내벽에 마찰되지 않고 자연스럽게 이동하도록 구성됨을 특징으로 하며, 이에 도시된 바와 같이, 원통형 케이블 홀더(210)의 둘레부에 일측이 힌지(310)를 통해 회동 가능하게 연결되며 자유단부에 바퀴(320)가 구비된 다수의 센터유지바(300)와, 센터유지바(300)와 케이블 홀더(210)의 둘레부 사이에 설치되어 센터유지바(300)의 바퀴(320)가 케이블관(3) 내면에 탄력 지지되도록 하는 탄성부재(330)를 포함하여 이루어진다.Figure 4 is a modified example of the transmission and distribution high-voltage cable pipeline entry apparatus according to the present invention, characterized in that the cable holder 210 is configured to move naturally without friction to the inner wall of the cable pipe (3), Similarly, one side of the cylindrical cable holder 210 is rotatably connected to one side through the hinge 310 and a plurality of center retaining bar 300 and the center holding bar 300 provided with a wheel 320 at the free end. And an elastic member 330 installed between the circumference of the cable holder 210 to allow the wheel 320 of the center support bar 300 to be elastically supported on the inner surface of the cable pipe 3.

이와 같은 구성에 의하면 고압 케이블(2)을 인입할 때 고압 케이블(2)이 센터유지바(300)에 의해 항상 케이블관(3)의 중심에 배치되어 케이블관(3)의 내면에 접촉되지 않으므로 고압 케이블(2)의 마찰력을 없앨 수 있으며 아울러 바퀴(320)의 구름력을 받게 되므로 인입이 더욱 쉽고 고압 케이블(2)의 손상을 막을 수 있다.According to this configuration, when the high voltage cable 2 is drawn in, the high pressure cable 2 is always arranged at the center of the cable pipe 3 by the center support bar 300 so that the inner surface of the cable pipe 3 is not contacted. The frictional force of the high-pressure cable 2 can be eliminated and the rolling force of the wheel 320 can be eliminated, thereby making it easier to pull in and prevent damage to the high-voltage cable 2.

이상에서 설명한 바와 같이, 본 발명에 따른 송배전 고압 케이블 관로내 인입장치에 의하면, 당김 와이어와 고압 케이블이 서로 꼬이지 않도록 연결되어 고압 케이블의 인입이 자유롭고 인입이 완료된 고압 케이블의 손상을 막을 수 있으며, 고압 케이블이 커플링을 매개로 하여 케이블 홀더에 연결됨에 따라 고압 케이블의 조임에 따른 손상이 방지됨은 물론 고압 케이블의 접촉력 증대로 이탈을 막을 수 있다.As described above, according to the transmission and distribution high-voltage cable pipeline entry device according to the present invention, the pull wire and the high-voltage cable is connected so as not to twist each other, free entry of the high-voltage cable and can prevent damage to the high-voltage cable is completed, the high-pressure cable As the cable is connected to the cable holder via the coupling, damage due to the tightening of the high voltage cable can be prevented as well as the separation can be prevented by increasing the contact force of the high voltage cable.

그리고, 고압 케이블이 센터유지바를 통해 케이블관의 내주면으로부터 이격됨에 따라 고압 케이블에 마찰저항이 발생되지 않으므로 고압 케이블의 손상을 막을 수 있고 인입작업이 용이한 효과가 있다.In addition, since the high-voltage cable is spaced apart from the inner circumferential surface of the cable pipe through the center support bar, friction resistance does not occur in the high-voltage cable, thereby preventing damage to the high-voltage cable and having an easy pulling-in operation.

이상, 본 발명을 본 발명의 원리를 예시하기 위한 바람직한 실시예와 관련하여 설명하고 도시하였지만, 본 발명은 그와 같이 도시되고 설명된 그대로의 구성 및 작용으로 한정되는 것이 아니다. 오히려, 첨부된 청구범위의 사상 및 범주를 일탈함이 없이 본 발명에 대한 다수의 변경 및 수정이 가능함을 당업자들은 잘 이해할 수 있을 것이다. 따라서, 그러한 모든 적절한 변경 및 수정과 균등물들도 본 발명의 범위에 속하는 것으로 간주되어야 할 것이다.While the invention has been described and illustrated in connection with a preferred embodiment for illustrating the principles of the invention, the invention is not limited to the configuration and operation as such is shown and described.
