In this case, the fixing part 230 of the wire fixing device 200 has an upper end disposed above the rotating shaft 214 of the insulator support part 210 to restrict the rotating body 213 from freely rotating. That is, when the rotating body 213 and the rotating shaft 214 of the insulator support part 210 are inserted into the fixing part 230, and the rotating body 213 rotates via the rotating shaft 214, the rotating body 213 ) Is in contact with the inner surface of the fixing portion 230 is limited the rotation angle.

상기와 같은 상태에서, 작업자는 도 5와 같이 애자부(220)의 애자부본체(221)로부터 애자부커버(222)를 분리하고, 가공배전선(L)을 애자부본체(221)의 내부에 안착시킨 후, 애자부본체(221)에 애자부커버(222)를 결합함으로써, 도 6과 같이 가공배전선(L)을 애자부(220)에 고정한다.In the state as described above, the worker separates the insulator cover 222 from the insulator body 221 of the insulator 220 as shown in FIG. 5, and the overhead line L to the inside of the insulator body 221. After mounting, the insulator cover 222 is coupled to the insulator body 221, thereby fixing the overhead line L to the insulator 220 as illustrated in FIG. 6.

이때, 상기 압력감지센서(400)는 가공배전선(L)에 의해 눌려지면서 일정압을 감지하여, 감지신호를 제어유닛(600)으로 출력한다.At this time, the pressure sensor 400 is pressed by the overhead distribution line (L) while detecting a certain pressure, and outputs a detection signal to the control unit 600.

상기와 같이 가공배전서(L)이 설치된 상태에서, 바람이 불면, 애자부(220)에 고정된 가공배전선(L)이 흔들리면서, 가공배전선(L)은 애자부(220)의 내면을 가압함과 동시에 압력감지센서(400)를 가압한다.In the state in which the processing distribution line (L) is installed as described above, when the wind blows, the processing distribution line (L) fixed to the insulator unit 220 is shaken, and the processing distribution line (L) presses the inner surface of the insulator unit 220. Simultaneously pressurizes the pressure sensor 400.

이때, 상기 압력감지센서(400)는 가공배전선(L)로부터 가해지는 압력을 감지하여, 제어유닛(600)에 감지신호를 출력하고, 이를 수신한 제어유닛(600)은 애자부(220)의 내면에 가해지는 압력을 판독하여, 가공배전선(L)의 흔들림 정도를 판단한다.At this time, the pressure sensor 400 detects the pressure applied from the overhead distribution line (L), and outputs a detection signal to the control unit 600, the control unit 600 receiving this is the insulator 220 The degree of shaking of the overhead distribution line L is determined by reading the pressure applied to the inner surface.

한편, 상기 가공배전선(L)이 강한 바람에 의해 허용치 이상 흔들리게 되고, 이러한 흔들림이 지속될 경우 가공배전선(L)이 단선될 위험이 있다. On the other hand, the overhead distribution line (L) is shaken more than the allowable value by strong wind, there is a risk that the overhead distribution line (L) is broken if this shaking is continued.

이때, 상기 가공배전선(L)이 허용치 이상 흔들리면, 압력감지센서(400)는 가공배전선(L)으로부터 기준값 이상의 압력을 받고, 이를 감지한 압력감지센서(400)는 제어유닛(600)으로 가공배전선(L)이 허용치 이상 흔들리고 있다는 신호를 출력하며, 이를 수신한 제어유닛(600)은 구동장치(500)를 구동시켜 애자지지부(210)의 스크류축(211)을 정방향으로 회전시킨다. 따라서 전선고정장치(200)의 고정부(230)가 스크류축(211)의 길이방향을 따라 하방으로 이동하고, 고정부(230)의 상단이 애자지지부(210)의 회동축(214)과 동일선상에 위치하면서, 도 7과 같이 애지지지부(210)의 회동체(213)의 회동반경이 커진다.At this time, when the overhead distribution line (L) is shaken more than the allowable value, the pressure sensor 400 receives a pressure higher than the reference value from the overhead distribution line (L), the pressure detection sensor 400 detects this is the overhead distribution line to the control unit 600 Outputs a signal that (L) is shaking more than the allowable value, the control unit 600 receives this to drive the drive device 500 to rotate the screw shaft 211 of the insulator support portion 210 in the forward direction. Accordingly, the fixing part 230 of the wire fixing device 200 moves downward along the longitudinal direction of the screw shaft 211, and the upper end of the fixing part 230 is the same as the rotation shaft 214 of the insulator support part 210. While being positioned on the line, the turning radius of the pivoting body 213 of the supporting portion 210 increases as shown in FIG. 7.

상기와 같이 회동체(213)의 회동반경이 커지면, 회동체(213)는 도 8과 같이 흔들리고, 이때 완충장치(300)는 흔들리는 애자부(220)를 탄발지지하면서 완충시킨다.When the turning radius of the rotating body 213 is increased as described above, the rotating body 213 is shaken as shown in FIG. 8, and the shock absorber 300 buffers the shaking insulator 220 while being elastically supported.

따라서, 상기 가공배전선(L)은, 강한 바람에 의해 흔들리면서 발생한 장력이 가공배전선(L)의 단부에 직접적으로 전달되지 않아, 가공배전선(L)을 통한 전력공급이 안정적으로 이루어진다.Therefore, in the overhead distribution line (L), the tension generated while shaking by strong wind is not directly transmitted to the end of the overhead distribution line (L), the power supply through the overhead distribution line (L) is made stable.

이후, 상기 바람이 잦아들어 가공배전선(L)에 가해지는 압력이 줄어들고, 이에 따라 압력감지센서(400)에 작용하는 압력이 기준값 이하로 떨어지면, 압력감지센서(400)는 이에 따른 신호를 제어유닛(600)으로 출력한다.Thereafter, when the wind is reduced, the pressure applied to the overhead distribution line (L) is reduced, whereby the pressure acting on the pressure sensor 400 falls below the reference value, the pressure sensor 400 controls the signal accordingly Output at (600).

이때, 상기 신호를 수신한 제어유닛(600)이 구동장치(500)를 구동시키면, 스크류축(211)이 역방향으로 회전하면서, 고정부(230)가 상부로 이동하여 원위치로 복귀하여, 도 1과 같이 된다.
At this time, when the control unit 600 receives the signal to drive the driving device 500, the screw shaft 211 is rotated in the reverse direction, the fixing unit 230 is moved upwards to return to the original position, Figure 1 Becomes

상술한 바와 같이, 본 발명에 따른 애자고정식 완철은, 가공배전선(L)의 유동각을 넓혀줌과 동시에 가공배전선(L)에 완충력을 제공함으로써, 강한 바람 등에 의해 가공배전선(L)에 허용치 이상의 장력이 작용할 시, 이를 적절하게 완충할 수 있어, 가공배전선(L)의 손상을 방지할 수 있다. As described above, the insulator-fixed wrought iron according to the present invention widens the flow angle of the overhead distribution line (L) and at the same time provides a buffering force to the overhead distribution line (L), thereby exceeding the allowable value for the overhead distribution line (L) by strong wind or the like. When the tension is applied, it can be appropriately buffered, it is possible to prevent damage to the overhead line (L).
