1 to 3, the GL stationary insulator 60 is installed to the iron 10 via a fastening means (bolt and nut) to insulate and fix the ground wire GL.

Referring to FIGS. 1 to 3 , the transformer 70 is installed on a utility pole P through a band (not shown) to convert high-voltage power into commercial power.

The inside of the transformer 70 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 70 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 70 can prevent problems such as failure due to overheating.

1, 2, and 6, the earth leakage detection sensor 80, the lightning detection sensor 90, the insulating oil tank 100, the circulation pump 110, the switching valve 120, the control unit 130, and the warning light (140) is explained as follows.

The earth leakage detection sensor 80 is installed in the wancheol 10 and serves to detect an earth leakage and output an earth leakage detection signal to the control unit 130.

The lightning detection sensor 90 is a known sensor, and in the case of the present embodiment, it is installed on the iron 10 to detect lightning in the surrounding area within a certain radius around the telephone pole P and transmits it to the control unit 130. do Since the lightning detection technology of the lightning detection sensor 90 is widely known in the related field, a detailed description thereof will be omitted.

The insulating oil tank 100 is installed in the iron 10 and filled with insulating oil therein.

The insulating oil filled in the insulating oil tank 100 is pressurized by the circulation pump 110 and injected into the transformer 70, and the insulating oil filled in the transformer 70 is pressurized by the circulation pump 110 and the insulating oil tank 100 ), the insulating oil discharged from the transformer 70 flows into the insulating oil tank 100 while being cooled through heat exchange with the cooling plate 71 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 iron 10 to pressurize the insulating oil inside the transformer 70 to flow into the insulating tank 100, and the insulating oil tank 100 It serves to pressurize the stored insulating oil to flow into the transformer 70. 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 70, and then the control unit 130), the path connected to the transformer 70 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 80, 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.

In addition, the control unit 130 receives the lightning detection signal from the lightning detection sensor 90 and compares it with a preset value, stores it if the area where the lightning occurs is within 1 km based on the telephone pole P, and stores it. It serves to control the operation of the warning light 140 so that the warning light 140 can operate if the area where the occurrence occurs is within 100 m based on the telephone pole P.

The warning light 140 is installed on the wancheol 10, and is operated by the control unit 130 to emit a warning light to the surroundings.

For example, in normal times, the insulating oil in the insulating oil tank 100 is pumped by the circulation pump 110 and introduced into the transformer 70 through the switching valve 120, and the insulating oil of the transformer 70 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 80 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.

On the other hand, when lightning strikes the surrounding area within a certain radius around the utility pole P, the lightning detection sensor 90 detects it and transmits it to the control unit 130, and the control unit 130 detects it and transmits it to the lightning detection sensor 90 The detection signal is received from the sensor and compared with a preset value.

At this time, if the area where lightning occurs is within 1km of the telephone pole P, it is counted and stored. The operation is controlled so that the manager can confirm the occurrence of lightning by looking at the light emitted from the warning light 140.

Therefore, since the administrator can easily grasp the occurrence frequency of lightning strikes in the surrounding area by looking at the number of lightning strikes stored in the control unit 130, it is possible to plan maintenance more systematically, thereby maximizing work efficiency.

7A to 7C are diagrams for explaining the operation of an overhead power distribution line connection facility having a monitoring function according to the present invention, and will be described with reference to them.

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 70 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 70 can be more easily controlled.

Meanwhile, when an earth leakage detection signal is input from the earth leakage detection sensor 80 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.

And, if the leakage detection signal is not input from the leakage detection sensor 80, the controller 130 controls the operation of the switching valve 120 to set a path so that the insulating oil in the insulating oil tank 100 flows into the transformer 70. will switch

On the other hand, when lightning strikes the surrounding area within a certain radius around the utility pole P, the lightning detection sensor 90 detects it and transmits it to the control unit 130, and the control unit 130 detects it and transmits it to the lightning detection sensor 90 The detection signal is received from the sensor and compared with a preset value.

At this time, if the area where lightning occurs is within 1km of the telephone pole P, it is counted and stored. The operation is controlled so that the manager can confirm the occurrence of lightning by looking at the light emitted from the warning light 140.

Therefore, since the administrator can easily grasp the occurrence frequency of lightning strikes in the surrounding area by looking at the number of lightning strikes stored in the control unit 130, it is possible to plan maintenance more systematically, thereby maximizing work efficiency.
