In this embodiment, the control unit (100) controls the operation of the first valve (70) and the second valve (82) so that the amount of insulating oil inside the transformer body (41) is maintained at an appropriate level when insulating oil is discharged from the transformer body (41). In addition, the control unit (100) can electrically control each electrical component as shown in FIG. 11, and it is preferable to communicate wirelessly with each electrical component. Meanwhile, in this embodiment, the control unit (100) can be installed on the outer surface of the transformer body (41), and its installation location can be varied in various ways as long as it can perform a control function.

[0080] FIGS. 12 to 15 are diagrams illustrating the operation of the present invention. With reference to FIGS. 12 to 15, the operation of the present invention is described as follows.

[0081] In the state installed in the present invention as shown in Fig. 2, when a small spark (small fire) occurs in the transformer (40), the small fire of the transformer (40) spreads to the abnormal indicator device (50) and to the receiving cap (60) containing insulating oil, and the fire can rapidly grow larger due to the insulating oil.

[0082] However, in the present invention, when the fire detection sensor (130) detects a fire, the third valve (143) is opened by the control unit (100), and as shown in FIG. 12, the foam extinguishing agent of the fire extinguishing tank (141) is sprayed through the spray nozzle (144) to the abnormal indicator device (50) and the receiving cap (60).

[0083] Therefore, the present invention can prevent a small fire in the transformer (40) from spreading into a large fire.

[0084] In addition, the present invention allows the position of the cutout switch (33) to be conveniently adjusted and installed according to changes in the installation environment of the power distribution facility.

[0085] That is, in the present invention, while the fixing bolt (120) is positioned as in FIG. 13, a connecting bracket (31) with a cutout switch (33) installed is inserted into the second arm (90), and while moving the connecting bracket (31) in the forward and backward directions, the connecting bracket (31) is positioned at a desired location as in FIG. 14, and then the connecting bracket (31) is fixed to the second arm (90) through a fastening member (34).

[0086] Afterwards, when the fixing bolt (120) is rotated to move to the left, the fixing bolt (120) is inserted into the fixing groove (92a) of the second reinforcing plate (92) as shown in FIG. 3.

[0087] At this time, the connecting bracket (31) is fixed by the fastening member (34), but after a long time, it can slide in the forward and backward directions.

[0088] However, in the present invention, the movement of the connecting bracket (31) is restricted by the fixing bolt (120), so the connecting bracket (31) does not slide in the forward and backward directions.

[0089] Meanwhile, the transformer (40) malfunction notification process in the present invention is described as follows.

[0090] When vibration occurs in the transformer (40) due to a decrease in the performance of the insulating oil inside the transformer (40), damage to the transformer equipment inside the transformer (40), etc., the vibration detection sensor (110) detects this.

[0091] At this time, when the vibration of the transformer (40) exceeds a reference value, the vibration detection sensor (110) outputs a vibration abnormality signal to the control unit (120), and the control unit (120) opens the first valve (70) for a certain period of time.

[0092] Then, the insulating oil contained in the transformer body (41) passes through the inside of the connecting pipe (51) and moves to the distribution space (52a) of the indicator (52), and at this time, as the color element (54) dissolves in the insulating oil, the insulating oil having color (hereinafter referred to as colored insulating oil) is discharged to the indicator slope surface (52c) through the branch discharge hole (52b).

[0093] Afterwards, the colored insulating oil flows along the marked slope surface (52c) as shown in FIG. 15, and the colored insulating oil that continues to move is received in the receiving cap (60).

[0094] In this way, when a color is displayed on the indicator slope (52c) through the colored insulating oil, the manager recognizes the need to inspect the transformer (40) through the color display on the indicator slope (52c).

[0095] Meanwhile, the control unit (120) can open the first valve (70) and simultaneously open the second valve (82) to maintain a certain amount of insulating oil inside the transformer body (41).

[0096] Additionally, the control unit (120) may open the second valve (82) after a certain amount of time has elapsed since opening the first valve (70).

[0098] The present invention as described above has the effect of preventing an initial fire from spreading into a large fire due to the insulating oil of the transformer (40) and the receiving cap (60) when an initial fire occurs in the transformer (40) or the abnormal indicator device (50) and the receiving cap (60).

[0099] In addition, the present invention allows the position of the cutout switch (33) to be freely moved as needed, thereby enabling the cutout switch (33) to be conveniently installed in response to various installation environments of power distribution facilities.

[0100] In addition, the present invention has the effect of making it easy to identify the transformer (40) abnormality on the ground by indicating the transformer (40) abnormality through the insulating oil of the transformer (40), and by including color in the insulating oil and indicating it on a truncated cone-shaped indicator (52).

[0101] In addition, the present invention can prevent colored insulating oil from falling to the ground and causing damage to pedestrians on the ground, thereby having the effect of preventing complaints from pedestrians on the ground.

[0102] In addition, the present invention is configured so that the transformer body (41), the connecting pipe (51), and the indicator (52) are separated, thereby providing the effect of convenient installation and replacement of the color element (54).

[0103] In addition, the present invention has the effect of preventing damage to the discharge port (43) by ensuring that the lower surface of the discharge port (43) of the transformer (40) is positioned above the lower surface of the support body (42), so that when the transformer (40) is placed on the ground before installing the fault indicator mechanism (50) on the transformer (40), the discharge port (43) does not come into contact with the ground.

[0105] Meanwhile, in the sense that the present invention further includes various structures applicable to overhead power distribution, such as a structure for fire suppression, in addition to a structure for overhead power distribution, the title of the present invention is defined as "safety-type overhead power distribution device equipped with a fire suppression function," and the subject of the claim of the present invention is defined as "overhead power distribution device."
