In general, large power generated in a power plant is transmitted to each substation as high-voltage power through transmission lines such as transmission towers, and then, after going through several stages of voltage transformation at the substation, the electric power is supplied to consumers such as homes or buildings using wires. It goes through a distribution process that is supplied to each region.

At this time, power supply to general consumers is supplied through telephone poles installed at regular intervals, and transmission and distribution lines in each telephone pole are connected using jumper wires.

That is, the transmission and distribution lines to be connected to the telephone pole are coupled through insulators on both sides of the wangeum installed horizontally on both sides of the upper end of the telephone pole, and the insulators are connected with jumper wires, but the connected jumper wires are installed at the top of the wangeum It was constructed and used so that it could be supported through an insulator.

In the case of the prior art as described above, there is an advantage in that overhead wires can be connected very easily, but there is a serious problem in that workers are concerned about electric shock because there is no way to check this when a short circuit occurs.

In addition, in the prior art, when birds nest around electric poles using tree branches, accidents such as electrical short circuits often occur due to tree branches.

The inside of the transformer 80 is filled with insulating oil for cooling heat generated during operation, and a cooling plate (71: heat sink) for discharging heat and cooling the insulating oil is installed on the outer surface.

In addition, the transformer 80 is configured to supply the cooled insulating oil from the insulating oil tank 100 by the circulation pump 110 and discharge the heated insulating oil to the insulating oil tank 100.

Accordingly, the transformer 80 can prevent problems such as failure due to overheating.

The leakage detection sensor 90, the insulating oil tank 100, the circulation pump 110, the switching valve 120, and the controller 130 will be described with reference to FIGS. 1 and 6.

The earth leakage detection sensor 90 is installed in the wangeum 10 and serves to detect an earth leakage and output an earth leakage detection signal to the control unit 130 .

The insulating oil tank 100 is installed in the wangeum 10, and the insulating oil is filled therein.

The insulating oil filled in the insulating oil tank 100 is pressurized by the circulation pump 110 and injected into the transformer 80, and the insulating oil filled in the transformer 80 is pressurized by the circulation pump 110 and the insulating oil tank 100 ), the insulating oil discharged from the transformer 80 flows into the insulating oil tank 100 while being cooled through heat exchange with the cooling plate 81 and the outside in the process of moving to the insulating oil tank 100.

The circulation pump 110 serves to circulate the insulating oil, and is installed in the wangeum 10 to pressurize the insulating oil inside the transformer 80 so that it flows into the insulating tank 100, and the insulating oil tank 100 It serves to pressurize the stored insulating oil to flow into the transformer 80. The operation of the circulation pump 110 is controlled by the control unit 130 to circulate the insulating oil at regular intervals.

The switching valve 120 is a valve that is operated and controlled by the control unit 130, and normally opens a passage so that the insulating oil pressured by the circulation pump 110 can flow into the transformer 80, and then the control unit 130), the path connected to the transformer 80 is changed to be connected to the wire connection unit 40.

The control unit 130 receives the leakage detection signal from the leakage detection sensor 90, and the switching valve 120 allows the insulating oil pressurized by the circulation pump 110 to flow into the powder storage tank 42 through the connector 43. ) plays a role in controlling the operation.

For example, at normal times, the insulating oil in the insulating oil tank 100 is pumped by the circulation pump 110 and introduced into the transformer 80 through the switching valve 120, and the insulating oil of the transformer 80 is also supplied to the circulation pump 110. It has a circulation structure in which it is pressurized by and re-introduced into the insulating oil tank 100.

However, when the leakage detection signal from the leakage detection sensor 90 is input to the control unit 130, the control unit 130 switches the path of the switching valve 120, and as a result, the insulating oil in the insulating oil tank 100 is transferred to the switching valve. It passes through (120) and flows into the inside of the wire connection unit (40).

The insulating oil introduced in this way flows into the powder storage tank 42 through the connector 43 and is then discharged through the end of the powder storage tank 42. and the insulating oil mixed with the fluorescent powder is discharged toward the jumper wire J through the end of the powder storage tank 42 and flows along the surface of the jumper wire J.

Therefore, as the insulating oil mixed with the fluorescent powder is applied to the surface of the jumper wire (J), the operator can intuitively recognize that a current leakage is occurring by looking at the fluorescent powder on the surface of the jumper wire (J), promptly maintenance can be performed.

7a to 7c are views for explaining the operation of the overhead distribution line support device having a bird access blocking function according to the present invention, and will be described with reference to this.

As shown in FIG. 1, in the installed state, the insulating oil in the insulating oil tank 100 is pumped by the circulation pump 110 at normal times and flows into the transformer 80 through the switching valve 120, and the The insulating oil also has a circulation structure in which it is pumped by the circulation pump 110 and re-introduced into the insulating oil tank 100.

Accordingly, heat generation of the transformer 80 can be more easily controlled.

Meanwhile, when an earth leakage detection signal is input from the earth leakage detection sensor 90 to the controller 130, the controller 130 switches the path of the switching valve 120, and as a result, the insulating oil in the insulating oil tank 100 is switched. It flows into the inside of the wire connection unit 40 via the valve 120.

Referring to FIGS. 7A to 7C , the introduced insulating oil is introduced into the powder storage tank 42 through the connector 43 and then discharged through the end of the powder storage tank 42 .

At this time, the insulating oil flows while being mixed with the fluorescent powder in the process of passing through the powder container 42a in which the fluorescent powder is stored, and the insulating oil mixed with the fluorescent powder passes through the end of the powder storage tank 42, that is, the discharge pipe 42c through the jumper wire ( J), and the discharged fluorescent powder and the insulating oil mixed in this way flow down along the surface of the jumper wire (J).

Therefore, as the insulating oil mixed with the fluorescent powder is applied to the surface of the jumper wire (J), the operator can intuitively recognize that a current leakage is occurring by looking at the fluorescent powder on the surface of the jumper wire (J), promptly This will allow you to perform maintenance.

On the other hand, if the leakage detection signal is not input from the leakage detection sensor 90, the controller 130 controls the operation of the switching valve 120 so that the insulating oil in the insulating oil tank 100 flows into the transformer 80. will switch
