송전선로용 접속애자 교체장비{Insulator change device for power cable}Connection insulator replacement device for power transmission line {Insulator change device for power cable}

본 발명은 송전선로용 접속애자 교체장비에 관한 것으로서, 더욱 상세하게는 접속애자의 손상 및 절연불량이 발생한 경우 이를 용이하게 교체할 수 있도록 하기 위한 교체장비에 관한 것이다.The present invention relates to a connection insulator replacement device for a transmission line, and more particularly, to a replacement device for making it easy to replace the damage and insulation failure of the connection insulator.

일반적으로, 애자는 송전선이나 전기기기의 나선 부분을 절연하고 동시에 기계적으로 유지 또는 지지하기 위하여 사용되는 자기로 만든 것이다.In general, insulators are made of porcelain, which is used to insulate and mechanically maintain or support the spiral of transmission lines or electrical equipment.

또한, 애자는 전기적으로 충분한 절연내력을 가지게 하기 위하여 다수의 주름을 만들어 표면에 따른 거리를 크게 하였다. 이것은 표면이 습하였을 때, 특히 염분이나 먼지 등이 부착되었을 때 절연내력이 저하되는 것을 방지하는 데 효과가 있다.In addition, the insulator made a large number of wrinkles in order to have a sufficient electrical insulation strength to increase the distance along the surface. This is effective in preventing the insulation strength from deteriorating when the surface is wet, especially when salt or dust is attached.

그리고, 애자의 주재료로는 경질자기를 사용하는데, 절연내력를 가지며 변질하지 않고 온도변화와 태양광선 등의 환경에도 강한 기계력을 가질 수 있도록 되어 있다.In addition, as the main material of the insulator, hard magnetic is used, and it has insulation strength and is capable of having a strong mechanical force even in environments such as temperature change and sunlight without altering.

상기 애자의 종류에는 송전선용:현수애자 ?장간애자 ?내무애자(태풍 때의 오손에 견딜 목적으로 사용), 배전선용:핀애자, 옥내배선용:놉애자 ?애관 ?클리트 애자, 차단기 ?피뢰기용:지지애자 등이 있다.The above types of insulators include: transmission line: suspension insulator, long-term insulator, interior insulator (used to withstand the fouling of typhoon), distribution line: pin insulator, indoor wiring line: knob insulator, insulator, cleat insulator, circuit breaker Supporters, etc.

한편, 애자가 낙뢰 및 기타 충격으로 파손되면, 송전선의 장력이 걸려있는 상태에서 애자를 교체하기에는 상당한 시간과 작업이 복잡하여 간편하게 할 수 있는 애자교체기가 요구되고 있다.On the other hand, if the insulator is damaged by lightning and other impact, it is required to replace the insulator in a state in which the tension of the transmission line is applied, and the insulator is required to be complicated and simple.

도 1은 일반적인 애자교체기를 나타낸 것이다.Figure 1 shows a typical insulator replacement.

도 1에 도시된 바와 같이, 애자교체기(100)는 끝단 양측에 형성되어 복수개의 애자(도시는 생략함)가 설치된 송전선(도시는 생략함)을 파지하는 제1 및 제2파지부재(112)(114)와, 상기 제1 및 제2파지부재(112)(114)의 양측에 일단부가 연결되고 타단부에 나사가 형성된 제1 및 제2볼트(116)(118)와, 상기 제1 및 제2파지부재(112)(114)에 대응되게 연결된 제1 및 제2볼트(116)(118)를 체결하고 사용자의 조작에 의해 체결된 제1 및 제2볼트(116)(118)를 왕복이동시켜 상기 제1 및 제2파지부재(112)(114)를 가깝게 또는 멀리 위치 가변시키는 레칫레버(200)로 구성된다.As shown in FIG. 1, the insulator replacement device 100 is formed at both ends of the first and second gripping members 112 for gripping a transmission line (not shown) provided with a plurality of insulators (not shown). 114, first and second bolts 116 and 118 having one end connected to both sides of the first and second gripping members 112 and 114 and having a screw formed at the other end thereof, and the first and second holding members 112 and 114. The first and second bolts 116 and 118 connected to the second holding members 112 and 114 are fastened, and the first and second bolts 116 and 118 fastened by a user's manipulation are reciprocated. It is composed of a ratchet lever 200 to move the position of the first and second holding members 112, 114 close or far away.

이와 같이 구성된 일반적인 애자교체기의 동작을 도 2를 참조하여 설명하면 다음과 같다.Referring to FIG. 2, the operation of the general insulator is configured as follows.

예를들어, 송전선에 설치된 불량애자가 세번째일 경우, 애자교체기(110)의 제1파지부재(112)를 첫번째 애자(130-1)의 일측에 설치하고, 제2파지부재(114)를 세번째 애자(130-3)의 일측에 설치한다.For example, when the defective insulator is installed on the transmission line for the third time, the first holding member 112 of the insulator replacement unit 110 is installed on one side of the first insulator 130-1, and the second holding member 114 is installed for the third time. It is installed on one side of the insulator 130-3.

그리고, 불량애자인 세번째 애자를 제거하기 위해, 레칫레버(200)를 시계방향으로 소정 횟수 돌린다. 이때, 제2볼트(118)가 우측으로 위치 가변된다. Then, in order to remove the third insulator that is the defective one, the ratchet lever 200 is rotated clockwise a predetermined number of times. At this time, the second bolt 118 is variable in position to the right.

상기 제2볼트(118)의 가변에 따라, 제2파지부재(114)가 우측으로 밀려나고 아울러, 네번째 애자(130-4)에 밀착되어 상기 네번째 애자(130-4)를 우측으로 밀어낸다.According to the variation of the second bolt 118, the second holding member 114 is pushed to the right and in close contact with the fourth insulator 130-4 to push the fourth insulator 130-4 to the right.

이에 따라, 세번째 애자(130-3)와 네번째 애자(130-4) 사이에 사용자의 손이 자유롭게 움직일 수 있도록 공간이 크게 발생한다.Accordingly, a large space is generated between the third insulator 130-3 and the fourth insulator 130-4 so that the user's hand can move freely.

그리고, 불량애자인 세번째 애자(130-3)를 손으로 파지하고, 가압한 후 제거한다.Then, the third insulator 130-3, which is a defective insulator, is gripped by hand, pressurized, and then removed.

이와같이, 종래 애자교체기는 교체하고자 하는 애자의 앞,뒤에 위치한 애자에 장치를 설치하여 장력을 잡은 상태에서 애자를 교체하게 되는 것으로서, 양 끝단 애자 요체용으로는 사용이 불가능한 문제점이 있었다.As such, the conventional insulator is to replace the insulator in the state in which the device is installed in the insulator located in front, the rear of the insulator to replace the insulator, there is a problem that can not be used for both ends of the insulator.

따라서, 종래에는 양 끝단의 애자를 교체하기 위해서는 캄아롱과 레바블럭 등의 추가적인 장비를 필요로 하게 되고, 이에 따른 작업능률 저하 및 설비 손상의 문제점이 있었다.
Therefore, conventionally, in order to replace the insulators at both ends, additional equipment such as camaron and rebar blocks is required, and thus there is a problem of deterioration of work efficiency and equipment damage.

먼저, 본 발명의 실시예에 따른 애자 교체장비의 구조를 도 3 및 도 4를 통해 살펴보면, 몸체의 일측에는 종래 애자교체기와 동일한 고정클램프(10)가 구성되고, 타측에는 연결용 걸쇠(20)가 구성되었으며, 고정클램프(10)와 연결용 걸쇠(20)에는 각각 제1볼트(11)와 제2볼트(12)가 상호 대향 방향으로 양측에서 연결 구성되었다.First, looking at the structure of the insulator replacement device according to an embodiment of the present invention through Figures 3 and 4, one side of the body is configured with a fixed clamp 10 the same as the conventional insulator replacement, the other side latch 20 for the connection The first clamp 11 and the second bolt 12 are configured to be connected at both sides in opposite directions to the fixed clamp 10 and the connecting clasp 20, respectively.

그리고, 제1볼트(11)와 제2볼트(12) 사이에는 종래 애자교체기와 동일하게 래칫레버(13)가 연결 구성되어 레버 회전에 따른 제1볼트(11)와 제2볼트(12) 상호간 이격거리 조절을 통한 장력 조절이 가능하도록 되어져 있다.In addition, the ratchet lever 13 is configured to be connected between the first bolt 11 and the second bolt 12 in the same way as the conventional insulator replacer, so that the first bolt 11 and the second bolt 12 are rotated by the lever. It is possible to control the tension by adjusting the separation distance.

한편, 본 발명에서의 연결용 걸쇠(20)는 분리된 부품이 아닌 하나의 일체형 부품으로 이루어져 일측이 개방된 "ㄷ"자형 형상을 이루고 있으며, 설치시 송전선로(2)와의 간섭을 방지하기 위해 중단에서 상향으로 일정각도(θ) 꺽여진 구조를 이루고 있다.On the other hand, the connection clasp 20 in the present invention is formed of one integral part instead of a separate part to form a "c" shape of one side is open, in order to prevent interference with the transmission line (2) during installation It is a structure that is bent at an angle (θ) upward from the middle point.
