일반적으로 전기철도는 전동차에 전기를 공급하기 위해 전차선로가 구성되고, 집전방식에 따라서 가공식과 제3궤조식으로 구분된다.In general, an electric railway is composed of a tram line for supplying electricity to an electric vehicle, and is classified into a processing type and a third trajectory type according to a current collecting method.

가공식은 동선을 궤조 상부에 가설하여 그 밑에 팬터그래프(pantograph)에 의하여 집전되며, 제3궤조식은 가선이 없는 방식으로 지하철 등에서 제2 급전레일을 노면 위에 설치하고 집전편에 의하여 전기을 공급하게 되어 있다.In the processing type, the copper wire is installed on the upper part of the railroad track, and is collected by a pantograph under it. In the third railing type, the second feed rail is installed on the road surface in a subway or the like without electricity, and electricity is supplied by the current collector piece.

가공식의 전차선로는 전동차에 직접 접촉하는 전차선과 이를 지지하는 전주, 급전선, 조가선 및 부속설비 등으로 구성된다.The overhead catenary is composed of a catenary that is in direct contact with the electric vehicle, and a pole, feeder, cockle, and accessories that support it.

상기 가공식은 도 1 및 도 2에 도시된 바와같이, 한전에서 AC 22,900V의 전기를 받아 DC 1,500V의 전기를 급전선(10)을 통하여 공급받고 상기 급전선(10)은 급전분기선(20)에 의해 인가된 전기를 전차선(30)으로 공급하도록 전차선로에 125m 간격 이내(열차편송 한도를 고려한 길이)로 가동브라켓식, 스팬선식, 인하식 등의 방법으로 급전분기가 설치되어 있으며, 일반적으로 가동브라켓식을 사용하며 가동브라켓(40)의 수평파이프(50)를 따라 가선되어 있다.As shown in FIGS. 1 and 2, the processing formula receives electricity of AC 22,900V from KEPCO, and receives electricity of DC 1,500V through the feeder line 10, and the feeder line 10 is fed by the feeder branch line 20. Feeding branch is installed by moving bracket type, span line type, cutting type, etc. within 125m interval (length considering train transfer limit) in the tram line to supply the applied electricity to the tram line 30. Using a formula is wired along the horizontal pipe 50 of the movable bracket (40).

상기 가동브라켓(40)은 전차선(30)과 조가선(60)을 일정한 높이로 지지하는 지지물이고, 상기 전차선(30)은 상기 가동브라켓(40)에 지지된 곡선당김금구(70)에 의해 지지되어 있다.The movable bracket 40 is a support for supporting the tramline 30 and the jaw wire 60 to a constant height, and the tramline 30 is supported by the curved pulley 70 supported by the movable bracket 40. have.

이러한 전차선로의 가선시스템은 상기 조가선(60), 급전선(10), 전차선(30) 등의 전선로와 전철주 등의 지지물, 그 이외에 피뢰기, 행거, 균압선, 각종 금구류, 절연애자 등의 장치가 부속설비로 사용되고 있다.Such a catenary system of a catenary system includes support devices such as electric wire lines, feeders 10, and catenary wires 30, railroad lines, etc., as well as devices such as lightning arresters, hangers, pressure equalizers, various metal fittings, and insulators. Is used as an accessory.

이때, 상기 급전분기선(20)은 가동브라켓(40)의 수평파이프(50)에 지지하기 위해 지지클램프(1)에 의하여 지지 결속된다.At this time, the feed branch line 20 is supported by the support clamp (1) to support the horizontal pipe (50) of the movable bracket (40).

이러한 지지클램프(1)에 대하여 도 3 및 도 4에 상세하게 도시되어 있다.This support clamp 1 is shown in detail in FIGS. 3 and 4.

즉, 종래의 지지클램프(1)는 한쌍의 상, 하부클램프금구(2,3)와, 상기 상,하부금구의 조립공(4,5)을 관통하여 끼움되는 U볼트(6)와, 상기 U볼트의 나사부에 나사조립되어 나사조임에 의해 상기 수평파이프(50)를 U볼트(6)와 상부 클램프금구(2) 사이와 상기 급전분기선(20)를 한쌍의 상기 상, 하부클램프금구(2,3)의 사이에 클램핑 조임하는 각각의 너트(N) 및 스프링와셔(S/W)로 구성되어 있다.That is, the conventional support clamp (1) is a U bolt (6) which is fitted through a pair of upper and lower clamp brackets (2,3), assembling holes (4,5) of the upper and lower brackets, and the U The screw is assembled to the threaded portion of the bolt to tighten the horizontal pipe 50 between the U bolt 6 and the upper clamping tool 2, and the feed branch line 20 by a pair of upper and lower clamp brackets 2, It consists of each nut (N) and spring washer (S / W) clamping and clamping between 3).

이때, 상기 절연덮개(400)는 상기 급전분기선(20)과 결합하기 위한 개구부(410)가 길이방향으로 절개 형성되고, 상기 클램프본체(100)와 클램프덮개(200)의 반구홈(160)(260)의 길이방향의 이탈을 방지하도록 양측에 이탈방지용 플랜지(420)가 형성된다.At this time, the insulating cover 400 has an opening 410 for coupling with the feeder branch line 20 is cut in the longitudinal direction, the hemisphere groove 160 of the clamp body 100 and the clamp cover 200 ( To prevent the departure in the longitudinal direction of the 260, the flange for preventing separation 420 is formed on both sides.

이러한 절연덮개(400)는 상기 급전분기선(200)의 외주면에 개구부(410)을 벌려서 끼움하고 상기 클램프본체(100)의 반구홈(160)에 일측 외주면을 끼움한다.The insulating cover 400 is fitted by opening the opening 410 to the outer peripheral surface of the feeder branch line 200 and fits one outer peripheral surface to the hemisphere groove 160 of the clamp body 100.

이러한 상태에서 상기 클램프덮개(200)의 반구홈(260)을 상기 절연덮개(400)의 타측 외주면에 끼움한 상태로 밀착한 상태에서 볼트헤드공(270)을 통하여 볼트(B)의 로드를 끼움하여 상기 클램프본체(100)의 볼트조립공(170)을 관통한 상태에서 스프링와셔(S/W)를 끼우고 너트(N)를 나사조립하여 조임하게 된다.In this state, the hemisphere groove 260 of the clamp cover 200 is inserted into the rod of the bolt B through the bolt head hole 270 in a state of being in close contact with the other outer peripheral surface of the insulating cover 400. By inserting the spring washer (S / W) in the state passing through the bolt assembly hole 170 of the clamp main body 100 is screwed to tighten the nut (N).

그 결과, 상기 클램프덮개(200)는 수직지지부(250)의 단턱부(255)가 클램프본체(100)의 수직지지부(150)의 단차부(155)에 의해 밀착되면서 멈춤되고, 상기 절연덮개(400)는 상기 양측의 반구홈(160)(260) 사이에서 개구부(410)가 수축되면서 급전분기선(20)의 외주면과 밀착된 상태로 조립되어 시공이 완료된다.As a result, the clamp cover 200 is stopped while the stepped portion 255 of the vertical support portion 250 is brought into close contact with the stepped portion 155 of the vertical support portion 150 of the clamp body 100, and the insulation cover ( 400 is assembled in close contact with the outer circumferential surface of the feed branch line 20 while the opening 410 is contracted between the hemisphere grooves 160 and 260 on both sides to complete the construction.

이때, 절연덮개(400)은 신축성 재질의 EPDM고무로 성형되어 급전분기선(20)의 온도변화에 의한 신축이 길이방향으로 제공되고, 이러한 급전분기선(20)의 신축 이동에도 상기 절연덮개(400)은 이탈방지용 플랜지(420)에 의해 상기 반구홈(160)(260)으로부터 이탈이 방지된다.At this time, the insulating cover 400 is formed of an elastic material EPDM rubber is provided by the expansion and contraction by the temperature change of the feeder branch line 20 in the longitudinal direction, the insulation cover 400 even in the stretching movement of the feeder branch line (20) The separation is prevented from the hemisphere grooves 160 and 260 by the separation prevention flange 420.

그리고 상기 절연덮개(400)에 의해 전차선로의 순환전류가 완전 차단되어 전식이 방식이 방지되어 구성부품의 국부마모를 차단되어 수명을 극대화하게 된다.The circulating current of the catenary lines is completely blocked by the insulating cover 400 to prevent the electroplating, thereby preventing local wear of components and maximizing the life.
