Control the operation.

The powder fire extinguisher 800 is a normal fire extinguishing means filled with fire extinguishing powder inside, and is provided with a spray pipe 810. In this embodiment, the operation is controlled by the control unit 700 to spray fire extinguishing powder into the spray pipe 810. ) is sprayed through.

The transmitter 900 receives an emergency signal from the control unit 700 and wirelessly transmits the emergency signal to a central control room (not specifically shown) where workers reside.

As an example, if a fire occurs in the underground distribution line (L), the fire detection sensor 500 detects this and outputs a fire detection signal to the control unit 700, and the control unit 700 detects the fire from the fire detection sensor 500. A fire detection signal is received to control the operation of the powder fire extinguisher (800).

And the powder fire extinguisher 800 is controlled by the control unit 700 to discharge fire extinguishing powder inside. The fire extinguishing powder discharged from the powder fire extinguisher 800 is sprayed through the spray pipe 810 to quickly extinguish the fire. Since the fire is extinguished, it is possible to minimize the spread and total destruction of the underground distribution line (L) caused by the fire.

In addition, the earth leakage detection sensor 600 detects an earth leakage and outputs a detection signal to the control unit 700, and the control unit 700 controls the operation of the transmitter 900. As a result, the transmitter 900 controls the operation of the control unit (700). The emergency signal received from 700) is output wirelessly.

As the emergency signal output wirelessly in this way is transmitted to the central control room (not specifically shown) where the worker resides, a quick response from the worker can be expected.

Figures 6a to 6c are diagrams illustrating the process of installing an underground distribution line using an underground distribution line hanger support mechanism for placing a power conduit for convenient remote management according to the present invention, which will be described with reference to the following.

As shown in FIGS. 1 and 6A, the connection portion 211 of the wire connection unit 200 is first inserted into the mounting portion 120 of the tray 100 and then secured with a fastening nut (N).

Meanwhile, when a fire occurs due to contact with a current-carrying conductor as penetrating water flows into the inside of the coated wire that has lost its protective function due to aging, the fire detection sensor 500 detects this and outputs a detection signal to the control unit 700. The control unit 700 receives a fire detection signal from the fire detection sensor 500 and controls the operation of the powder fire extinguisher 800.

And the powder fire extinguisher 800 is controlled by the control unit 700 to discharge fire extinguishing powder inside. The fire extinguishing powder discharged from the powder fire extinguisher 800 is sprayed through the spray pipe 810 to quickly extinguish the fire. Since the fire is extinguished, it is possible to minimize the spread and total destruction of the underground distribution line (L) caused by the fire.
