[0090] The control unit (80) opens the first air control valve (63) when it receives a motion detection signal from the motion detection sensor (70), and opens the second air control valve (66) when it receives a fire detection signal from the fire detection sensor (110). In this embodiment, the control unit (80) can be installed on the crossarm (10) as shown in FIG. 5. In addition, the control unit (80) can control the operation of the motion detection sensor (70), the first and second air control valves (63, 66), and the air generator (64). Meanwhile, in this embodiment, the control unit (80) can drive the compressor (64b) to charge compressed air into the compression tank (64a) when the compressed air in the compression tank (64a) is below a reference value. In addition, in this embodiment, the control unit (80) can communicate with the motion detection sensor (70), the first and second air control valves (63, 66), and the compressor (64b) via wired or wireless communication.

[0092] FIGS. 10 to 12 are diagrams illustrating the operation of the present invention. With reference to FIGS. 10 to 12, the operation of the present invention is described as follows.

[0093] In a state as shown in FIGS. 2 and FIGS. 3, if a fire occurs in the transformer (T), the fire detection sensor (110) detects this and outputs a fire detection signal to the control unit (80).

[0094] Then, the control unit (80) opens the second air control valve (66) to supply air to the striking body (101).

[0095] At this time, the striking bar (102) moves toward the fire extinguisher (92) by air pressure and strikes the fire extinguisher (92), and as the fire extinguisher (92) breaks, the liquid extinguishing material inside the fire extinguisher (92) is discharged to the outside.

[0096] Then, the liquid fire extinguishing agent is guided by the guide (140) to the transformer (T), and the fire in the transformer (T) is extinguished.

[0097] In addition, in a state as shown in FIGS. 5 and 6, when a bird approaches the wire connection mechanism (40), the motion detection sensor (70) detects this and outputs a motion detection signal to the control unit (80).

[0098] Then, the control unit (80) opens the first air control valve (63) so that air is supplied to the injection nozzle (61).

[0099] At this time, air is sprayed from the spray nozzle (61) and pushes the rotating collision plate (32) upward, and the rotating collision plate (32) rotates as shown in FIG. 11 and repeatedly collides with the horizontal plate (31b) of the fixed collision plate (31), and the impact sound is propagated to the surroundings by this collision.

[0100] Then, birds around the wire connector (40) are startled by the sound of the impact (warning sound) and move away from the wire connector (40).

[0101] Meanwhile, the initial response process to the risk of fire in the present invention is as follows.

[0102] In the state where the present invention is installed as shown in FIG. 8, if a problem (e.g., overcurrent) occurs in the connection between the conductor (J1) of the jumper wire (J) and the first and second connectors (43a, 43b) and the connector (43) overheats, the plug (42) melts due to the high temperature and opens as shown in FIG. 12, so that the liquid fire extinguishing agent in the liquid fire extinguishing agent receiving part (41b) passes through the spray hole (43) and flows into the first and second conductor inlet holes (43a1, 43b1).

[0103] At this time, the present invention allows for rapid initial response to the risk of ignition caused by the overcurrent by cooling and suffocating the surroundings as the liquid extinguishing agent vaporizes in the first and second conductor inlet holes (43a1, 43b1), and can rapidly suppress the fire in the initial stage if it occurs due to the overcurrent.

[0104] In addition, the assembly process of the wire connection mechanism (40) in the present invention is as follows.

[0105] In the present invention, a plug (42) is fitted into a spray pipe (41c) through a wire inlet hole (41a1) of a connecting mechanism body (41), and a first connector (43a) and a second connector (43b) are inserted into the wire inlet hole (41a1) so that the first connector (43a) and the second connector (43b) face each other.

[0106] At this time, when the first connector (43a) and the second connector (43b) are brought together to form the connector member (43), a seating support groove (43c) and a spray hole (43d) are formed in the connector member (43), and the plug (42) is wrapped by the seating support groove (43c). Then, the plug (42) is stably supported by the bottom of the seating support groove (43c) and closes the spray hole (43d), so that when the liquid fire extinguishing agent is injected into the liquid fire extinguishing agent receiving portion (41b), the liquid fire extinguishing agent in the liquid fire extinguishing agent receiving portion (41b) is safely received in the liquid fire extinguishing agent receiving portion (41b).

[0107] Afterward, when the fastening member (44) is fastened to the first and second fastening holes (43a1, 43b1) of the first and second connectors (43a, 43b), the wire connection mechanism (40) is securely assembled. Once the assembly of the wire connection mechanism (40) is completed in this manner, a liquid fire extinguisher is injected into the liquid fire extinguisher receiving portion (41b) through the liquid fire extinguisher injection port (41d).

[0108] Next, the wire connection device (40) is installed on the jumper wire support insulator (20), and the jumper wire (J) is inserted into the wire connection device (40). Then, the jumper wire (J) is fixed to the main body of the connection device (41) through the bending member (50), so the jumper wire can be safely installed.

[0109] Meanwhile, in the present invention, the wire connection mechanism (40) is provided to be disassembled and assembled, and the reason for this is as follows.

[0110] In the present invention, the plug (42) is made of thermoplastic plastic, the connecting mechanism body (41) is made of thermosetting plastic (41), and the connector member (43) is made of metal, so there is a problem in that it is difficult to manufacture the wire connecting mechanism (40) by molding materials with different melting points at once (for example, insert molding).

[0111] Accordingly, the present invention can produce a wire connection mechanism (40) that can be assembled robustly by manufacturing each component separately but making it convenient to assemble.

[0113] The present invention as described above can quickly suppress a fire when it occurs near a transformer (T), thereby enabling a rapid response to the occurrence of a fire.

[0114] In addition, the present invention has the effect of easily repelling birds by transmitting a striking sound (warning sound) to the surroundings when birds are detected.

[0115] In addition, the present invention has the effect of manufacturing a wire connection mechanism (40), which is difficult to produce in a single molding process, into individual components, while allowing each individual component to be assembled conveniently and robustly and disassembled conveniently.

[0116] In addition, since the present invention is easy to assemble and disassemble, even if the present invention is used and overheating occurs at the connection part between the jumper wire (J) and the connector member (43), the present invention can be reused (recycled) by simply replacing the plug (42). Therefore, the present invention has the advantage of being easy to maintain (manage).

[0117] In addition, the present invention has the effect of more efficiently responding to overheating of the connection part between the jumper wire (J) and the connector member (43) when a gap is created between the wires (J1) of the jumper wire (J) by the first and second wire stoppers (43a2, 43b2) and a liquid fire extinguishing agent flows into the first and second wire inlet holes (43a1, 43b1) through the spray hole (43d).

[0118] In addition, the present invention allows for convenient disconnection and connection of jumper wires (J), and by disconnecting the jumper wires (J) as needed, it has the effect of enabling convenient power distribution work.

[0119] In addition, the present invention has the effect of efficiently suppressing the spread of fire by allowing a liquid fire extinguishing agent to be supplied to the connection part between the jumper wire (J) and the connector member (43) as the plug (42) melts, even without a separate detection sensor, so that when overheating (fire) occurs at the connection part between the jumper wire (J) and the connector member (43), the temperature of the connection part is lowered below the ignition point and the area around the connection part is suffocated, thereby enabling a rapid initial response to the occurrence of overheating.

[0121] Meanwhile, in the sense that the present invention further includes various structures for overhead power distribution, such as fire suppression structures, in a structure that supports overhead power distribution lines such as jumper wires, the title of the present invention is defined as 'safety-enhancing overhead power distribution line support device utilizing LP insulators' and the subject of the claim of the present invention is defined as 'overhead power distribution line support device'.
