6 and 7 are functional diagrams showing the insulator for supporting the distribution line according to the present invention. Referring to FIGS. 6 and 7, the insulator for supporting the distribution line according to the present invention will be described as follows.

First, a transformer 40 and a light emitting unit 50 are installed in the jump selection unit 30.

Thereafter, after installing the wrought iron connecting portion 10 and the spring (S) on the wrought iron (F), the jump wire J1 of the jump wire (J) connected to the processing wire (L) introduced into the telegraph pole (P) When inserted into the insertion portion 31a of the 30, the covering J2 of the jump line J is inserted into the jump bow portion 32a of the jump liner 30, so that the conducting wire J1 of the jump line J is The jump selection unit 30 is not exposed outside. At this time, the first covering fixing part 32d of the insulating part 32 is opened at a predetermined interval when the jump line J is inserted.

Subsequently, the bolt 33 on which the cap 34 is fitted is threadedly coupled to the first bolt fastening portion 31b of the jump wire fixing mechanism conductive portion 31 and the first bolt fastening portion 32c of the insulation portion 32. While pressing the conductive wire J1 of the jump line J downward, the conductive wire J1 is fixed to the jump line fixing unit 30.

Subsequently, when the nut 35 is threaded to the first covering part 32d of the insulating part 32, the first covering part 32d is tightened by the nut 35, and the jump line J is formed. It is fixed to the jump selection unit 30. Therefore, the jump line J is fixed to the jump line deciding portion 30 more stably.

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. At this time, when the power is supplied again, electricity flows to the conductive portion 31 of the jump selection unit 30, and the transformer 40 supplied with the power from the conductive portion 31 steps down the voltage to emit light. ), The light emitting unit 50 is turned on.

In the state as described above, if the abnormality occurs in each of the processing wire (L) and the electricity is not passed to the jump selection unit 30, the light emitting unit 50 is turned off, the operator through the light off of the light emitting unit 50 The abnormality of the overhead wire L or the jump selection unit 30 can be confirmed.

In addition, when the wind blows on the jump line J, the agile body 10 is rotated as shown in FIG. 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.

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.

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.

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.

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.
