본 발명은 특고압 송전용 가공선 고정애자에 관한 것이다.The present invention relates to overhead line fixing insulator for extra-high voltage transmission.

일반적으로, 발전소에 발생되는 대전력은 송전선로를 통해 고압의 전력으로 각 변전소로 송전된 다음, 변전소에서 여러단계의 변압과정을 거쳐 각 가정 또는 건물 등의 수용가로 공급된다.In general, the large power generated in the power plant is transmitted to each substation with high-voltage power through the transmission line, and then supplied to the customers of each home or building through a multi-stage transformation process in the substation.

이때, 일반 수용가에 대한 전력공급은 일정간격으로 설치되는 전신주를 통해 공급되고, 각 전신주에서의 가공전선 연결은 점프선을 통해 이루어진다.At this time, the power supply to the general consumer is supplied through the telephone poles installed at regular intervals, the overhead wire connection in each telephone pole is made through a jump line.

도 1은 종래의 가공전선 연결을 나타낸 도면으로서, 도 1를 참조하여 종래의 가공전선 연결을 살펴보면, 다음과 같다. 1 is a view showing a conventional overhead wire connection, looking at the conventional overhead wire connection with reference to Figure 1, as follows.

한편, 상기 전신주(P)로부터 인출되는 가공전선(L)과 연결된 점프선(J)을 상기와 같은 방법으로 점프선고정부(30)에 고정시키면, 점프선(J)을 통한 가공전선(L)의 연결이 도 2와 같이 완료된다.Meanwhile, when the jump line J connected to the overhead wire L drawn out from the telephone pole P is fixed to the jump line fixing part 30 in the same manner as above, the overhead wire J is connected to the overhead wire J through the jump wire J. This is completed as shown in FIG.

상기와 같은 상태에서, 점프선(J)으로 바람이 불면, 도 6과 같이 애자부(20)가 회전하게 된다. 이때, 회전하는 점프선고정부(30)는, 다수의 스프링(S)의 인장 또는 수축에 의해 완충되어, 점프선(J)의 도선(J1)과 볼트(33)의 연결부에 걸리는 하중이 약해져, 점프선(J)의 도선(J1)과 점프선고정부(30)의 도전부(31)가 안정적으로 연결된다. In the above state, when the wind blows on the jump line J, the insulator part 20 rotates as shown in FIG. 6. At this time, the rotating jump line fixing portion 30 is buffered by the tension or contraction of the plurality of springs S, and the load applied to the connection portion between the conductor J1 of the jump line J and the bolt 33 is weakened, and the jump line Conductor J of (J) and the conductive portion 31 of the jump selection unit 30 are stably connected.

또한, 가공전선(L)에 이상이 발생하여 가공전선(L)을 보수해야할 경우, 해당 이상지점으로의 전력공급을 차단하여야 한다.In addition, when an abnormality occurs in the overhead wire (L) to repair the overhead wire (L), the power supply to the corresponding abnormal point should be cut off.

이때, 변전소로부터 해당 이상지점까지의 전력을 차단하게 되면, 변전소에서 해당 이상지점까지의 전력라인이 모두 차단되어, 변전소와 해당 이상지점 사이에서 전력을 소모하는 수용가는 전력을 사용할 수 없게 된다.In this case, when the power to the abnormal point is cut off from the substation, all the power lines from the substation to the abnormal point are cut off, and consumers who consume power between the substation and the abnormal point cannot use the power.

하지만, 본 발명의 경우, 변전소로부터의 전력을 차단하지 않은 상태에서, 해당 이상지점 바로 전 전신주(P)로부터 인출되는 가공전선(L)을 고정한 볼트(33)를 풀러, 도 7과 상기 가공전선(L)을 점프선고정부(30)로부터 해제하면, 상기 전신주(P)까지는 전력이 계속적으로 공급되는 상태에서, 상기 전신주(P)로부터 해당 이상지점으로까지만 전력공급이 되지 않는다.However, in the present invention, in the state of not interrupting the power from the substation, the bolt 33 holding the overhead wire L drawn out from the telephone pole P immediately before the abnormal point is loosened, Figure 7 and the overhead wire When (L) is released from the jump selection unit 30, power is not supplied only from the telephone pole P to the abnormal point while power is continuously supplied to the telephone pole P.

따라서, 해당 이상지점을 보수하는 동안, 불필요하게 모든 수용가로의 전력이 차단되지 않아, 해당 이상지점과 상관없는 수용가의 전력공급에 차질이 발생하지 않는다.Therefore, while repairing the abnormal point, power to all consumers is not cut off unnecessarily, and no disruption occurs in the power supply of the customer irrespective of the abnormal point.
