Description

가공송전 선로용 점퍼선 연결고정장치{JUMPER CABLE CLAMP APPARATUS FOR OVERHEAD TRANSMISSIONLINE}JUMPER CABLE CLAMP APPARATUS FOR OVERHEAD TRANSMISSIONLINE}

본 발명은 애자와 점퍼선, 점퍼선과 송전가공선로를 안정적으로 보호하면서 연결고정할 수 있는 가공송전 선로용 점퍼선 연결고정장치에 관한 것이다.
The present invention relates to a jumper wire connection fixing device for overhead transmission line that can be securely connected while protecting the insulator, jumper wire, jumper wire and the transmission line.

일반적으로 각 수용가에 공급되는 전력의 대부분은 도시와 교외 등 거의 모든 지역에 걸쳐 포설되어 있는 송전선로를 통하여 이루어지고 있는데, 이러한 송전선로의 종류에는 땅속에 직접 전력선을 매설하는 지중선로와, 철탑(또는 콘크리트 장주) 및 절연 애자를 이용하여 지상에서 소정 높이 위의 공중에 전력선을 지지 설치하는 가공선로 두 가지가 있다.In general, most of the power supplied to each customer is provided by transmission lines that are installed in almost all areas, such as cities and suburbs. Such types of transmission lines include underground lines and steel towers that directly bury power lines in the ground. Alternatively, there are two overhead lines for supporting power lines in the air above a predetermined height on the ground using concrete poles and insulators.

여기서, 지중선로는 부가적인 보조장치들이 필요치 않아서 설치가 간단하다는 장점이 있는 반면, 별도의 절연매개물 없이 땅속에 매설되어 대지와 직접 접촉되므로, 매설되는 전력선 자체적으로 써어지 전압 및 상용주파수전압에 대한 절연이 가능하도록 제조해야 하기 때문에 고가의 비용이 든다는 문제점이 있다.Here, the underground line has the advantage that it is simple to install because no additional auxiliary devices are required, while the underground line is buried directly in the ground without a separate insulation medium, so that the embedded power line itself has a surge voltage and a commercial frequency voltage. There is a problem in that expensive cost because it must be manufactured to enable the insulation.

이러한 비용상의 문제점으로 인해 현재는 가공선로가 송전선로의 주류를 <4> 이루고 있으며, 앞으로도 가공선로의 비율이 지속적으로 높아질 것으로 예상된다. 그리고, 가공선로는 실제 수용가에 공급되는 전력을 수송하기 위한 전력선과, 낙뢰로 인해 전력선에 유기되는 뇌전압을 감소시키기 위한 가공지선 및 불평형 요인으로 인한 발생전류를 유인하는 중성선으로 구성되어 있는바, 상기 전력선의 지지방식에 따라, 크게 현수형과 내장형의 두 가지로 나누어질 수 있다.Due to these cost problems, the overhead line is currently the mainstream of transmission lines, and the proportion of overhead lines is expected to continue to increase. In addition, the overhead line is composed of a power line for transporting the power supplied to the actual consumer, a overhead line for reducing the lightning voltage induced by the lightning strike and a neutral line attracting the generated current due to the unbalance. According to the support method of the power line, it can be divided into two types, suspension type and built-in type.

참고로, 내장형 방식의 경우에는 상기 가공선로를 지면으로부터 소정 높이 위에 이격위치시키기 위한 철탑의 양측에 상기 전력선에 양 끝단을 별도의 내장클램프를 통해 각각 고정 지지한 후, 점퍼선을 통해 상기 전력선을 상호 접속시키게 되는데, 이때 철탑의 양측을 가로지르게 되는 상기 점퍼선을 상기 철탑으로부터 소정 거리 이격 지지하기 위해, 상기 철탑으로부터 소정 거리 떨어진 위치에 수평재용 강관을 고정 설치한 후, 이 강관 외주면에 상기 점퍼선을 고정시킴으로써 상기 점퍼선을 지지하도록 하는 점퍼장치를 사용하고 있다.For reference, in the case of the built-in type method, the two ends of the power line are fixedly supported on both sides of the power line to separate the overhead line from the ground by a separate built-in clamp, respectively, and then the jumper wire is used to support the power line. In this case, in order to support the jumper wires crossing the both sides of the steel tower at a predetermined distance from the steel tower, the steel pipe for horizontal members is fixedly installed at a position away from the steel tower, and then the jumper is formed on the outer circumferential surface of the steel pipe. A jumper device is used to support the jumper wire by fixing the wire.

그런데, 상기 점퍼장치 설치후 상기 점퍼선에 대하여 직각방향으로 부는 바람에 의해서, 상기 점퍼장치가 바람이 부는 방향으로 진동을 하게 되고, 이러한 진동이 있을 경우에는, 안전상의 요건으로 인해 상기 점퍼선과, 점퍼장치 주변의 충전부나, 철탑 자체 등과의 사이에 구비하여야할 필요 최소거리가 커지게 되므로, 가능한 진동량을 적게 하는 것이 경제적이고, 이에 따라 상기 수평재용 강관에 횡진억제용 중량물을 부가함으로써 진동량을 줄이고 횡진특성을 개선하게 된다.However, after the jumper device is installed, the jumper device vibrates in the windy direction due to wind blowing at right angles to the jumper wire, and in the case of such vibration, the jumper wire and Since the minimum distance to be provided between the charging portion around the jumper device and the steel tower itself is increased, it is economical to reduce the amount of vibration as much as possible, and thus the amount of vibration by adding a transverse suppression weight to the horizontal steel pipe. It can reduce and improve the lateral characteristics.

상기 횡진억제용 중량물을 상기 수평재용 강관에 장착하기 위해, 종래에는 수평용재 강관의 상부 외주면 일측에 가대지지축을 용접고정하고, 상기 가대지지축에 연접하여 말굽모양의 횡진억제용 중량물을 필요한 숫자만큼 상호 밀착되도록 설치한 후, 최외곽측 중량물에 연접하도록 별도의 가대지지축을 다시 용접 고정한 다음, 최종적으로, 상기 양측 가대지지축의 상부에 소정 직경의 구멍을 뚫어 별도의 봉을 관통 결합함으로써, 상기 수평재용 강관의 진동시 상기 장착된 횡진억제용 중량물이 외부로 떨어져 나오지 않도록 하였었다.In order to mount the transverse restraint heavy material on the horizontal steel pipe, the mount support shaft is welded to one side of the upper outer circumferential surface of the horizontal steel pipe, and connected to the mount support shaft, and the horseshoe-shaped transverse restraint heavy material is required as many as necessary. After installation so as to be in close contact with each other, by welding again fixing the separate mount support shaft to be in contact with the outermost heavy material, and finally, by drilling a hole of a predetermined diameter in the upper portion of the both mount support shaft through the separate rod, When the vibration of the steel pipe was vibrated so that the mounted transverse restraint weight did not fall to the outside.

그러나, 상기와 같은 방법을 사용하여 횡진억제용 중량물을 설치할 경우에는, 외관상으로 좋지 않고, 설치개수가 많아질 경우 이들을 고정하는데 어려움이 있으며, 설치개수만큼 풍압면적이 커지므로 이를 위한 중량물이 추가로 필요하게 되는 것은 물론, 단위수량의 중량을 높이는데 한계가 있으므로 부품수량이 많아지게 된다는 문제점이 있다.However, in the case of installing the lateral suppression heavy article by using the method as described above, it is not good in appearance, it is difficult to fix them when the number of installation is large, and as the number of installation wind pressure area becomes larger, the weight for this additional Of course, there is a problem in that the quantity of parts increases because there is a limit in increasing the weight of the unit quantity.

그러므로 이를 개선하고자 종래에는 철탑으로부터 소정 거리만큼 떨어지도록 고정 장착되어, 상기 점퍼선을 지지하는 강관; 및 상기 강관에 장착되어, 상기 점퍼선의 진동량을 감소시키는 다수의 횡진억제용 중량물로 구성된 것이 제안(특허공개번호 특1999-0049129호)된 바 있다.Therefore, in order to improve the conventional art, the steel pipe fixedly mounted to be separated by a predetermined distance from the steel tower to support the jumper wire; And a plurality of transverse restraint heavy materials mounted on the steel pipe to reduce the amount of vibration of the jumper wire (Patent Publication No. 1999-0049129).

이는 상술한 기술에 비해 횡진 특성이 우수하고, 미관이 수려한 장점이 있는 반면, 이 역시 상술한 기술과 마찬가지로 고하중의 횡진억제용 중량물을 이용하는 관계로 그다지 외관상으로 보기 좋지 않고, 설치 개수가 많아질 경우 이들을 고정하는데 어려움이 있으며, 설치 개수만큼 풍압면적이 커지므로 이를 위한 중량물이 추가로 필요하게 되는 것은 물론, 단위수량의 중량을 높이는데2한계가 있으므로 부품수량이 많아지게 된다는 문제점이 있다.Compared to the above-described technology, the transverse characteristics are superior and the beauty of the beauty is excellent.However, like the above-described technology, the heavy load of the transverse suppression weight is not used. In this case, there is a difficulty in fixing them, and since the wind pressure area is increased as much as the number of installations, there is a problem in that the weight is required for this, as well as the number of parts increases because there are two limits to increase the weight of the unit quantity.

그러므로, 상술한 문제점을 개선하고자 최근에는 점퍼선을 구성하는 각각의 도선을 상호 이격지지하기 위한 소정 형상의 몸체; 상기 몸체의 외주면을 따라 등간격으로 구비되되, 상기 몸체에 착탈 자유롭도록 결합된 다수의 클램프 암; 및 상기 각 클램프 암의 끝단에 돌출 형성되어 상기 각 도선을 지지하는 클램프를 포함하여 구성된 점퍼 스페이서가 제안(특허공고번호 10-0250634호) 되어 이용되고 있다.Therefore, in order to improve the above-mentioned problem, recently, a body having a predetermined shape for supporting each conductive line constituting a jumper line is spaced apart from each other; A plurality of clamp arms provided at equal intervals along the outer circumferential surface of the body, the clamp arms being detachably attached to the body; And a jumper spacer protruding from the end of each clamp arm and including a clamp to support each of the conductive wires (Patent Publication No. 10-0250634).

이는 가공 송전 선로의 내장형 철탑의 양측에 각각 연결된 전력선을 상호 전기적으로 접속시켜주는 점퍼선에 연결 설치되어, 자체 중량과 지지력을 통해 바람에 의한 진동시 또는 기타 전기적인 사고에 의한 진동시에 점퍼선을 구성하는 각 도선 간에 충돌없이 항상 일정한 간격을 유지시킬 수 있도록 한 것이다.It is connected to a jumper wire that electrically connects power lines connected to both sides of the built-in steel tower of the overhead transmission line, so that the jumper wire can be used in case of vibration by wind or vibration by other electric accident through its own weight and supporting force. It is to maintain a constant gap at all times without collision between each conductor.

그러나, 이 기술은 앞서 말한 종래의 기술들에 비해 비교적 설치를 신속 용이하게 이룰 수 있는 장점이 있는 반면, 상술한 발명들에 비해 경량이므로 바람에 의한 진동시 또는 기타 전기적인 사고에 의한 진동시에 송전 선로 또는 철탑에 부딪히는 현상이 초래되는 비안전한 문제점이 있다.However, this technique has the advantage of being relatively quick and easy to install compared to the above-mentioned conventional techniques, while being lighter than the above-described inventions, the power transmission during vibration by wind or vibration by other electrical accidents There is an unsafe problem in which the phenomenon of hitting the track or steel tower is caused.

결과적으로 상술한 종래 기술 모두는 공통적으로 고하중을 취하는 중량물을 이용하여 점퍼선의 횡진을 최소화할 수 있도록 한 것이므로 많고 적고의 차이는 있으나 설치를 신속 용이하게 취할 수 없는 문제점은 물론이고, 철탑 상에 조류가 둥지를 틀기 유리한 공간을 제공하게 되는 문제점이 있다.As a result, all of the above-described prior arts have a lot of small and small differences, but the problem of not being able to take the installation quickly and easily on a steel tower, since all of the above-described prior arts are made to minimize the transverse of the jumper wire by using a heavy load that is commonly used. There is a problem that the birds provide a favorable space for nesting.

또한, 예상치 못한 다소 강한 바람에 의한 진동시 또는 기타 전기적인 사고에 의한 진동시에는 상기 중량물을 통해 횡진을 효과적으로 저지하기란 사실상 불가능하고, 오히려 선로 또는 철탑의 부분적인 파손을 초래하는 문제와 더불어 상기 중량물을 추락시킬 우려가 다분한 매우 비안전한 문제점이 있다.In addition, it is virtually impossible to effectively prevent traversing through the weight during unexpectedly strong wind vibrations or vibrations caused by other electrical accidents, but rather with the problem of causing partial breakage of the track or steel tower. There is a very unsafe problem that the risk of falling weight fall.

그리고, 송전 선로에 하중을 전가시켜 늘어짐 현상과 같은 악영향을 초래시키는 문제점과, 철탑 자체 등과의 사이에 구비하여야할 필요 최소거리를 커지게 하므로, 비경제적인 문제점이 있다.In addition, there is a problem of causing an adverse effect such as a sagging phenomenon by transferring a load to a transmission line, and increasing the minimum distance to be provided between the steel tower itself and the like, thereby causing an uneconomic problem.

한편, 일반적인 가공송전 선로용 점퍼선 연결고정장치는 송전철탑의 암 단부에 지지대가 형성되어 있고, 지지대에 점퍼선지지애자의 상단이 고정되며, 점퍼선지지애자의 하단에 고정장치로 점퍼선이 고정된다.On the other hand, in general, a jumper wire connection fixing device for overhead transmission line is formed with a support on the arm end of the transmission tower, the top of the jumper wire insulator is fixed to the support, and the jumper wire is fixed to the bottom of the jumper wire insulator It is fixed.

이러한 구조에서 점퍼선을 고정하였을 때, 점퍼선지지애자와 같이 고정장치가 지나치게 경직되어 계속적으로 가해지는 진동력에 의하여 쉽게 파손되는 문제가 발생된다.
In this structure, when the jumper wire is fixed, the fixing device is excessively stiff, such as a jumper wire insulator, which causes a problem of being easily broken by the vibration force applied continuously.

본 발명은 상기한 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 애자와 점퍼선, 점퍼선과 송전가공선로를 안정적으로 보호하면서 연결고정할 수 있도록 하므로서, 강한 바람에 의해 애자와 점퍼선이 유동되지 않도록 할 수 있는 가공송전 선로용 점퍼선 연결고정장치를 제공하는데 그 목적이 있다.
The present invention has been made to solve the above problems of the prior art, so that the insulator and the jumper wire, the jumper wire and the transmission line can be securely connected and secured, so that the insulator and jumper wire is not flowed by the strong wind. The object of the present invention is to provide a jumper wire connection fixing device for overhead transmission lines.
