Description

간격유지용 절연 가이더를 이용한 배전선로의 무정전 바이패스 공법Uninterrupted Bypass Method for Distribution Lines Using Insulating Guiders for Space Maintenance
본 발명은 각 전주에 연결 배선된 배전선로의 교체 및 이설과 경과지 변경공사를 위한 배전선로 공법에 있어, 특히 임시로 설치되는 조가선과 간격유지용 절연 가이더 및 바이패스 케이블과 그 바이패스 케이블 상의 접속분기구를 이용하여 안정적인 전력의 공급을 유지할 수 있게 하면서도 공중 가선 상태의 바이패스 케이블에 의해 작업 안전성을 크게 향상시킨 것이며, 바이패스 케이블의 사용 수명은 연장시키면서도 분기접속의 용이함과 함께 그 분기접속부의 손상이나 훼손을 방지한 간격유지용 절연 가이더를 이용한 배전선로의 무정전 바이패스 공법에 대한 것이다.The present invention in the distribution line method for the replacement and relocation of the distribution lines connected to each pole and the change of transition site, in particular the temporary guide line and the insulation guider and the bypass cable for maintaining the spacing and the connection on the bypass cable It is possible to maintain a stable power supply by using a branch outlet, and greatly improve the work safety by the bypass cable in the aerial line state. It is about uninterrupted bypass method of distribution line by using insulating guider for keeping gap that prevents damage or damage.
전력수요의 급증에 따라 이에 대응한 전력설비가 계속 확충되고 있으며, 전력 사용자의 전기품질에 대한 요구수준이 높아지면서 순간의 정전도 민원의 대상이 되어 보상청구 등과 같은 전기 사용자의 집단행동과 소송사례가 증가하고 있는 실정이어서 배전공사시에 양질의 전력공급을 위해 전력을 차단하지 않는 상태에서 배전공사가 이루어지는 무정전 공법이 이루어지고 있다.In response to the surge in demand for electricity, electric power facilities have been expanded in response. As the demand for electric quality of electric power users increases, momentary power failures are also subject to civil complaints. As the situation is increasing, the uninterruptible construction method is performed in which the power distribution construction is performed without cutting the power for supplying high quality power during the power distribution construction.
일반적인 무정전 공법에 의한 배전공사는 통상적으로 이동용 변압기차와 바이패스 케이블 및 공사용 개폐기 등으로 구성되어 있는 것으로서, 바이패스 케이블을 설치하여 전력 공급을 바이패스되게 한 후 배전선로의 교체 및 이설작업을 실시하고 다시 바이패스 케이블을 철거하여 배전공사가 완료되는 것이다.In general, the uninterruptible power distribution work is composed of a mobile transformer car, a bypass cable, a construction switch, and the like. The bypass cable is installed to bypass the power supply, and then the distribution line is replaced and moved. After that, the bypass cable is removed and the power distribution work is completed.
즉, 기존의 바이패스 케이블을 이용한 임시송전공법은, 공사구간 내에 분기선로와 특고압 수용가 및 설비가 있을 경우 공사구간의 전원 및 부하 측을 공사용 개폐기와 길이 50m의 바이패스 케이블을 다수의 중간 접속재로 임시로 접속하여 전원을 공급하면서 공사구간의 점퍼선을 활선 작업으로 분리하고 시공하는 방법으로서, 통상적으로 무정전전공 4명과 배전전공 4명 및 보통인부 4명이 필요되고, 활선작업차 1대 이상과 공사용 개폐기 2대 및 바이패스 케이블 차량 1대가 요구된다.In other words, the temporary transmission method using the existing bypass cable, if there is a branch line and the special high-voltage customer and equipment in the construction section, the power switch and load side of the construction section and a bypass cable of 50m length and a number of intermediate connection materials As a method of separating and constructing jumper wires in the construction section while supplying power temporarily by wire work, it is usually required 4 uninterrupted electricians, 4 power distribution majors and 4 ordinary workers. Two construction switches and one bypass cable car are required.
이러한 무정전 바이패스 공법에 의한 설치순서는, 공사용 개폐기를 우선 설치한 상태에서 공사용 개폐기 외함에 접지선을 연결하고 접지를 하며, 공사용 개폐기 설치주에 여유장 처리 금구 및 케이블 클램프를 설치하고, 중간케이블 및 분기케이블 포설하고, 중간케이블을 접속한 후, 분기케이블 접속하고, 중성선 및 전력선을 방호 조치하고, 주상작업자는 전원 측과 분기 측 및 부하 측에 임시걸이 및 가지지크리트와 케이블 클램프를 설치한다.The installation procedure by the uninterrupted bypass method is connected to the ground wire in the enclosure of the construction switchgear while the construction switch is installed first, and the grounding bracket and the cable clamp are installed on the construction switch holder. Install branch cable, connect intermediate cable, connect branch cable, protect neutral cable and power line, and column worker install temporary hanger, branch crete and cable clamp on power side, branch side and load side.
이어, 공사용 개폐기 부싱에 케이블 연결하고, 분기선로 케이블을 연결하며,전원측과 부하측 및 케이블 본선에 연결하고, 전원측과 부하측 공사용 개폐기를 투입하게 되며, 분기선로 전력선에 케이블 연결하고, 전원측과 부하측 점퍼선 절단한 후 작업전 작업구간 검전 접지 시공 후 작업을 실시하게 되는 것이다.Then, connect the cable to the switchgear bushing for construction, connect the branch line cable, connect the power supply side and load side and the cable main line, input the power supply side and load side construction switch, connect the cable to the branch line power line, and connect the power supply side and the load side jumper wire. After cutting, the work section is performed before the test work.
그러나, 상기한 종래의 바이패스 케이블을 이용한 임시송전공법은 다음과 같은 문제점이 있다.However, the temporary transmission method using the conventional bypass cable has the following problems.
첫째, 바이패스 케이블의 설치와 철거 작업의 반복으로 케이블 손상과 접속개소의 접속재 마모, 이물질오염 등으로 인한 불안전한 접속이 발생하여 안전사고의 위험 등 안전성의 문제가 있는 것으로서, 현재 임시송전공법용으로 사용되는 바이패스 케이블은 지상에 포설되는 것이므로, 작업을 시행할 때마다 설치와 철거를 반복하여 케이블의 안전을 장담할 수 없는 실정이며, 만일 케이블이 손상되었을 경우에는 지락으로 인한 정전사고뿐만 아니라 케이블이 손상된 부근에 작업자 및 보행자가 접근하였을 경우 감전사고로 이어지는 것이다.First, there is a safety problem such as the risk of safety accident due to unsafe connection due to cable damage, wear of the connection material and contamination of foreign materials by repeated installation and removal of bypass cable. The bypass cable used for installation is installed on the ground, so it is not possible to guarantee the safety of the cable by repeating installation and dismantling every time the work is performed, and if the cable is damaged, Workers and pedestrians near the damaged cable may lead to electric shock.
또한, 50m 단위의 바이패스 케이블을 직선 접속재로 임시접속하고, 분기선로의 경우는 분기 접속재로 임시접속하는 일이 반복적으로 이루어져 접속 개소의 마모 및 오염이 발생하는데, 이는 접속 개소 및 케이블의 열화로 이어지고, 완전한 접속이 이루어지지 않아 접속 개소에서 전기저항이 증가하는 요인으로 작용하는 것이다.In addition, the 50m-bypass unit is temporarily connected with a straight connection member, and in the case of a branch line, the temporary connection with the branch connection member is repeatedly performed, causing wear and contamination of the connection point, which is caused by deterioration of the connection point and the cable. Subsequently, since the complete connection is not made, the electrical resistance increases at the connection point.
둘째, 케이블 허용용량이 5,000kVA이므로 작업구간의 부하용량을 5,000kVA이하로 낮추기 위하여 타 선로로 부하전환을 시행하여야 하기 때문에 작업 종료 시 까지 전환을 받은 선로가 전력 계통 운영이 불안하고 작업 전 부하전환을 위한 개폐기 조작에 따른 오조작으로 인한 정전사고 등 인력과 시간 낭비되는 문제가 있다.Second, because cable allowance is 5,000kVA, load switching to other line should be performed to lower the load capacity of working section below 5,000kVA. There is a problem that wastes manpower and time, such as power failure accidents due to incorrect operation according to the operation of the switch.
즉, 서로 분리된 도체를 접속하는 경우에는 원래의 도체에 비해 전기적으로 저항이 증가할 수밖에 없으며, 전기적 저항이 증가함에 따라 당연히 전압강하가 발생하게 되는데, 통상적으로 접속 개소 1개소당 약 5%의 전압강하가 발생하여, 케이블 허용용량이 5,000kVA이라는 것은 바이패스 케이블 포설 시 직선 또는 분기접속을 고려하여 케이블이 견딜 수 있는 안전한 용량을 산정한 것으로서, 접속 개소를 줄인다면 그에 따른 전압강하를 줄일 수 있기 때문에 동일 케이블을 사용하더라도 더 많은 용량의 부하에 견딜 수 있으며, 송전효율이 증가되어 부하용량에 따른 부하전환의 불편한 절차도 특별한 경우(부하용량 10,000kVA 이상)를 제외하고는 시행할 필요가 없어지는 것이다.In other words, when connecting separate conductors, the resistance is inevitably increased compared with the original conductor, and as the electrical resistance increases, a voltage drop naturally occurs. Generally, about 5% of each connection point is used. When voltage drop occurs and cable allowance is 5,000kVA, it calculates safe capacity that cable can endure in consideration of straight line or branch connection when installing bypass cable. If the connection point is reduced, the voltage drop can be reduced. Therefore, even if the same cable is used, it can endure the load of more capacity, and the power transmission efficiency is increased so that the inconvenient procedure of load switching according to the load capacity does not need to be performed except in special cases (load capacity of 10,000kVA or more). Will.
셋째, 작업 도중 일기불순으로 인한 돌발적인 상황 발생 시 이미 설치해 놓은 바이패스 케이블의 충전부와 노출된 접속 개소가 지상에 방치되어 안전상의 위험은 물론 전력 계통의 정상 복귀가 불가능하여 대규모 정전을 일으킬 가능성이 매우 크다.Third, in the event of accidents due to weather irregularities during work, the live parts of the bypass cable and the exposed connection points that are already installed are left on the ground, which may lead to large-scale power outages as well as safety risks and impossibility of returning to the power system. Very large.
이러한 문제점은 케이블을 지상이 아닌 주상에 가공으로 설치하면 해결할 수 있는데, 현행 배전선로 무정전 작업 시 필요에 따라서는 바이패스 케이블을 조가선을 이용하여 주상에 가공으로 설치하도록 되어 있지만, 실제로는 바이패스 케이블의 가공 설치를 위한 안전성을 확보해 줄 수 있는 부수적인 공구나 명확한 시공 방법이 없기 때문에 곤란을 겪고 있는 것이 현실이다.This problem can be solved by installing the cable into the column on the ground rather than on the ground. In the current uninterrupted line, if necessary, the bypass cable is installed on the column using the coarse wire. It is a reality that there are no additional tools or clear construction methods that can ensure the safety for machining installation.
넷째, 바이패스 케이블을 이용한 임시송전공법을 수행하기 위해서 도급업체는 바이패스 케이블을 비롯하여 부수적으로 따르는 고가의 장비와 공구를 보유하여야 하는데, 반복사용으로 인한 마모와 파손으로 인해 케이블과 접속재 등을 주기적으로 교체해야 하므로 도급업체로서는 상당한 경제적 부담으로 작용하게 되는 것이다.Fourthly, in order to perform the temporary transmission method using the bypass cable, the contractor should have the expensive equipment and tools accompanying the bypass cable as well as the accompanying equipment. As a result, the contractor would have a significant economic burden.

도 1은 본 발명에 의한 배전선로의 무정전 바이패스 시공예시도이다.1 is a view illustrating an uninterrupted bypass construction of a distribution line according to the present invention.
본 발명이 종전의 바이패스 케이블을 이용한 임시송전공법과 차별화되는 점은 크게 두 가지로서, 지상에 포설하던 바이패스 케이블을 간격유지용 절연 가이더를 이용하여 주상에 가공으로 설치한다는 점과 이때 사용되는 새롭게 고안된 바이패스 케이블은 중간접속을 하지 않으며 필요 시 분기접속연결이 가능하도록 구성하여 케이블의 접속 개소를 최소화하고, 케이블 접속에 따라 발생되는 다양한 문제점들을 보완할 수 있다는 점이다.The present invention is distinguished from the temporary transmission method using the conventional bypass cable in two ways. The bypass cable installed on the ground is installed in the column by using the insulation guider for maintaining the gap and used at this time. The newly designed bypass cable does not have an intermediate connection, and it can be configured to enable branch connection if necessary, minimizing the connection point of the cable and compensating for various problems caused by the cable connection.
이와 같이 차별화된 작업방법에 대해 좀 더 구체적으로 설명하면,In more detail, this differentiated work method,
먼저, 도 2의 도시와 같이 작업구간 내에 바이패스 케이블 설치를 위한 조가선(10)을 가선하는데, 조가선(10)의 위치는 특고압 중성선(11)의 하부(저압선이 가선되어 있는 경우에는 저압선 하부)에 충분한 지상고가 나오도록 하며, 전선이선기구로 사용되는 핀장주 완금 고정장치(20)와 완금연장 보조암(30)을 이용하여 조가선(10)이 전주(100)(100')에서 이격되도록 가선한다.First, as shown in FIG. 2, the wires 10 are wired for the installation of the bypass cable in the working section, and the position of the wires 10 is lower than the low voltage line when the low voltage line is wired. ), And the cable line 10 is spaced apart from the electric pole 100, 100 'by using the pinjangju complete fixing device 20 and the perfect extension auxiliary arm 30, which are used as wire wire mechanisms. do.
다음으로, 설치된 조가선(10)에 도 3의 도시와 같이 새로 고안된 간격유지용 절연 가이더(40)를 필요하다고 판단되는 위치에 안전을 고려하여 적당히 설치한다. Next, the newly installed spacing maintaining insulation guider 40, as shown in FIG.
이때 상기한 간격유지용 절연 가이더(40)는 전력선 설치 시 중요하게 여겨지는 간격(Offset)을 감안하여 외부 충격이나 진동으로 인하여 이탈하는 상황이 발생하는 경우 3상의 전선이 서로 닿지 않도록 하는 삼각 구조로 전선이 고정되는 부분에 개폐레버(41a)에 의해 개폐되는 공간부(41)(41')를 형성하여 가선작업 및 철거작업이 용이하도록 구성되었으며, 각 상 전선 간의 이격거리는 활선 안전거리(22.9kV의 경우 30cm)이상이 되도록 절연체로 구성하되, 전선이 고정되는 연결부는 누설전류에 대비하여 폴리머 현수애자의 하우징과 같은 형태로 형성하며, 조가선(10)에 고정하는 부분과 삼각의 간격유지용 절연 가이더(40)를 서로 연결하는 연결대(42)는 절연로프 또는 폴리머 현수애자 등의 연결수단을 사용하여 길이조절 기능을 두어 필요에 따라 삼각의 간격유지용 절연 가이더(40)에 설치되는 바이패스 케이블(50)(50')의 지상고를 조절할 수 있도록 하였다.In this case, the insulation guider 40 for maintaining the gap has a triangular structure in which the three-phase electric wires do not touch each other when a situation occurs due to an external shock or vibration in consideration of an offset, which is considered important when installing a power line. The spaces 41 and 41 'which are opened and closed by the opening / closing lever 41a are formed on the part where the electric wires are fixed, so that the wire work and the dismantling work can be easily performed, and the safety distance between each phase wire is a live safety distance (22.9 kV). In the case of 30cm) or more, but the insulator so that the wire is fixed in the form of the housing of the polymer suspension insulator in preparation for the leakage current, the portion to be fixed to the bare wire (10) and the insulation for maintaining the gap between the triangle The connecting rod 42 connecting the guiders 40 to each other has a length adjusting function using a connecting means such as an insulation rope or a polymer suspension insulator, and a triangular gap oil as necessary. The ground clearance of the bypass cable 50, 50 'provided in the insulating guider 40 were to be adjusted.
이와 같은 간격유지용 절연 가이더(40)를 설치한 후, 도 4의 도시와 같이 작업구간 양측에 공사용 개폐기(60)(60')를 바이패스 케이블(50)(50')이 설치되는 높이에 맞추어 전주(100)(100') 위에 설치한다. After installing the insulating guider 40 for maintaining the gap, as shown in FIG. 4, the construction switch 60, 60 ′ is installed at both sides of the work section at a height at which the bypass cables 50, 50 ′ are installed. The poles are installed on the poles 100 and 100 '.
다음으로 도 5의 도시와 같이 3상의 바이패스 케이블(50)(50')을 가선하는데, 이때 사용되는 바이패스 케이블(50)(50') 역시 새로 고안된 것으로서, 무정전 작업 시 케이블의 중간접속이 필요 없게 하였는데, 이는 무정전 작업 구간 내의 간선이나 주 부하선로의 케이블 중간에 접속 개소를 두지 않아 케이블 접속으로 인해 발생되는 상기한 여러 문제점을 해소하는 본 발명의 매우 중요한 장점이라 할 수 있다.Next, as shown in FIG. 5, the three- phase bypass cable 50, 50 ′ is wired. The bypass cable 50, 50 ′, which is used at this time, is also newly designed. Although not required, this is a very important advantage of the present invention to solve the above-mentioned problems caused by the cable connection is not placed in the middle of the cable of the main load line or the trunk line in the uninterrupted work section.
즉, 상기한 바이패스 케이블(50)(50')에는 없는 분기접속구(70)(70')를 일정간격으로 연속 형성하여, 무정전 작업구간 내에 분기선로가 있어, 이 분기선로에 전력을 공급해야 하는 경우 간단하게 분기접속구(70)(70')를 개방하여 분기선로와 연결되는 분기전력선(80)을 접속함으로써 용이하게 분기선로에 전력을 공급할 수 있도록 하였으며, 이러한 분기접속구(70)(70')는 배전선로의 경간(특고압 선로의 경우 경간 당 약 50m)을 감안하여 바이패스 케이블의 50m 마다 구성하여 작업구간 내에 분기선로가 있을 경우, 도 6의 도시와 같이 해당하는 위치에 있는 분기접속구(70)(70')를 사용하여 분기선로와 접속시킬 수 있도록 구성하였다.That is, the branch connection ports 70 and 70 'which are not included in the bypass cables 50 and 50' are continuously formed at a predetermined interval, and there is a branch line in the uninterruptible work section to supply power to the branch line. In this case, the branch connection lines 70 and 70 'are simply opened to connect the branch power lines 80 connected to the branch lines so that the branch lines 70 and 70' can be easily supplied to the branch lines. ) Is configured every 50m of the bypass cable in consideration of the span of the distribution line (about 50m per span in the case of the special high voltage line), and when there is a branch line in the work section, the branch connection port at the corresponding position as shown in FIG. (70) and (70 ') were configured to be connected to the branch line.
또한, 도로횡단 개소의 경우에는 차량의 통행이 가능한 위치로 간격유지 가이더(40)의 높이를 조절하여 바이패스 케이블(50)(50')을 포설해서 보행자 및 차량의 통행을 원활하게 한다.In addition, in the case of the road crossing point, the bypass cable 50, 50 'is laid by adjusting the height of the space keeping guider 40 to a position where the vehicle can pass, so that pedestrians and vehicles pass smoothly.
이와 같은 간격유지용 절연 가이더(40)에 의해 포설된 상태의 바이패스 케이블(50)(50')은 작업 중 갑작스런 일기변화에 따른 대처가 가능하여 전력계통이 안정적이고, 안전사고를 방지할 수 있으며 기타 나머지의 작업 절차는 일반적으로 시행되는 기존의 바이패스 케이블을 이용한 임시송전공법의 절차에 따르면 된다.The bypass cables 50 and 50 'installed in the state of the insulation guider 40 for maintaining the gap can cope with a sudden change of weather during work, so that the power system is stable and safety accidents can be prevented. The rest of the work procedures can be done in accordance with the procedures of the temporary transmission method using conventional bypass cables.
이와 같은 무정전 바이패스 공법에 있어서, 상기한 조가선은 도 7의 도시와 같이 전주에 장착되는 공지의 핀장주 완금 고정장치(20)와 그 핀장주 완금 고정장치(20)에 체결되는 공지의 완금연장 보조암(30)을 이용하여 설치되는 것으로서, 상기한 조가선(10)이 전주로부터 이격된 상태로 설치되게 하는 것이다.In the uninterruptible bypass method as described above, the above-mentioned barbed wire is a known complete extension that is fastened to a known pin head complete device 20 and the pin head complete device 20 mounted on the pole as shown in FIG. As installed by using the auxiliary arm 30, the above-mentioned clapper 10 is to be installed in a state spaced apart from the pole.
또한, 상기한 조가선(10)으로부터 그 바이패스 케이블(50)(50')이 공중 설치되면서도 3상의 케이블이 서로 균일 이격되게 하기 위한 간격유지 가이더는 도 8의 도시와 같이 바이패스 케이블(50)(50')이 이격 삽입되기 위한 삼각 형태의 틀로 이루어져 있고, 그 내측으로는 바이패스 케이블(50)(50')과의 마찰을 감소시켜 가선 및 철거를 용이하도록 한 롤러(41)(41')가 회전 가능한 상태로 고정되어 있는 것이다.In addition, while maintaining the bypass cable 50, 50 'is installed in the air from the barbed wire 10, evenly spaced guider for the three-phase cable evenly spaced from each other as shown in Figure 8 bypass cable 50 (50 ') is composed of a triangular frame for spaced insertion, roller 41, 41' to reduce friction with the bypass cable (50) (50 ') to facilitate the wire and dismantle the inside ) Is fixed in a rotatable state.
특히, 상기한 간격유지용 절연 가이더(40)와 조가선(10)을 이어주기 위한 연결대(42)의 경우 다양한 구성을 통해 그 길이 조절을 가능하도록 한 것인데, 가장 단순하게는 절연로프 등을 이용하여 이들을 서로 연결함으로써 상기한 간격유지용 절연 가이더(40)의 높이를 조절하여 그 바이패스 케이블(50)(50')의 높이를 간편하게 조절할 수 있는 것이며 절연 폴리머 현수애자를 연결대로 이용할 경우에는 더욱 확실한 절연효과를 얻을 수 있는 것이다.Particularly, in the case of the connection table 42 for connecting the insulation guider 40 and the conical wire 10 for maintaining the gap, the length can be adjusted through various configurations, and most simply by using an insulation rope or the like. By connecting them to each other, it is possible to easily adjust the height of the bypass cables 50 and 50 'by adjusting the height of the insulating guider 40 for maintaining the gap. Insulation effect can be obtained.
또한, 상기한 바이패스 케이블(50)(50')에는 도 9의 도시와 같이 일정간격을 갖는 분기접속구(70)(70')가 형성되어 있는 것으로서, 상기한 분기접속구(70)(70')는 케이블에 고정된 상태의 고정체(71)와 그 케이블로부터 슬라이딩되는 유동체(72)로 이루어져 있는 것이며, 그 유동체(72)의 내측에 해당하는 바이패스 케이블(50)(50')의 피복을 절개하여 그 내부의 전도체가 노출되게 한 피복제거부(51)가 형성되어 있으므로, 분기전력선(80)을 이용하여 분기선로와 연결하고자 하는 경우에는 해당 위치에 형성되어 있는 분기접속구(70)(70')의 유동체(72)를 고정체(71)로부터 분리 이격시킨 후 노출 상태의 피복제거부(51)에 상기한 분기전력선(80)을 접속하고 절연보호커버(73)로 덮으면 되는 것이다.In addition, the bypass cables 50 and 50 'are provided with branch connectors 70 and 70' having a predetermined interval as shown in FIG. 9, and the branch connectors 70 and 70 'are formed as shown in FIG. ) Consists of a fixed body 71 fixed to the cable and a fluid 72 sliding from the cable, the sheath of the bypass cables 50, 50 'corresponding to the inside of the fluid 72. Since the cover removing part 51 is formed to cut the exposed portion to expose the conductor therein, when the branch power line 80 is to be connected to the branch line, the branch connection part 70 formed at the corresponding position ( 70 ') is separated from the stationary body 71, and the above-mentioned branch power line 80 is connected to the cover removing unit 51 in an exposed state, and covered with an insulating protective cover 73.
이에 따라 도 10의 도시와 같이 무정전 바이패스 공법을 위한 배전선로에 있어 전주와 전주 간의 시공예를 살펴보면, 각 전주(100)(100')에는 핀장주 완금고정장치(20)와 완금연장 보조아암(30)에 의해 조가선(10)과 간격유지용 절연 가이더(40)가 각각 설치되고, 그 간격유지용 절연 가이더(40)는 상기한 조가선(10) 상에도 설치되게 된다.Accordingly, looking at the construction example between Jeonju and Jeonju in the distribution line for the uninterruptible bypass method as shown in FIG. 10, each Jeonju 100, 100 'has a pinjangju complete fixing device 20 and the arm extension arm The coarse wire 10 and the space keeping insulating guider 40 are respectively provided by 30, and the space keeping insulating guider 40 is provided on the above barbed wire 10 as well.
또한, 상기한 간격유지용 절연 가이더(40)를 통해 바이패스 케이블(50)(50')을 서로 이격되게 분할 가선하여 시공되는 것이며, 이들 바이패스 케이블(50)(50')에 형성된 분기접속구(70)(70')를 통해 분기전력선(80)이 접속된 형태를 갖게 된다.In addition, the bypass cables 50 and 50 'are divided and wired apart from each other by the above-described space maintaining insulation guide 40, and the branch connection ports formed in these bypass cables 50 and 50' are constructed. The branch power lines 80 are connected through the 70 and 70 ′.
따라서, 종래와 같이 절단 형태의 바이패스 케이블을 연결 사용하거나 그 바이패스 케이블을 절단하여 접속하는 등의 불편함을 제거하는 한편, 그와 같은 작업에 의해 발생하는 전기적 저항 및 발열, 취약 파손 등을 효과적으로 방지하게 되는 것이다.Therefore, the conventional method eliminates the inconvenience of connecting and using a bypass cable of a cutting type or cutting the bypass cable, and prevents electrical resistance, heat generation, and fragile damage caused by such operations.
