상기 경보장치(100)는, 별도로 마련된 상황실에 설치되며, 제어유닛(90)에 의해 작동제어되어, 제어유닛(90)으로부터 경보신호를 수신하면 시각적 또는 음성적으로 외부에 알린다.The alarm device 100 is installed in a separate situation room, and is operated and controlled by the control unit 90 so as to visually or externally notify the outside when an alarm signal is received from the control unit 90.

즉, 상기 경보장치(100)는, 화재의 발생을 상황실의 관리자에게 시각적으로 알리기 위해 디스플레이장치가 사용되거나 음성적으로 알리기 위해 음성장치가 사용될 수 있으며, 디스플레이장치와 음성장치가 동시에 사용될 수도 있다.That is, the alarm device 100, a display device may be used to visually notify the manager of the situation room of the occurrence of a fire, or a voice device may be used to inform the voice, the display device and the voice device may be used at the same time.

상기 소화기구(110)는, 내부에 소화가스가 압축 저장되어, 배전반케이스(10)의 상면에 설치되는 케이스(G2)에 내설되는 소화가스저장탱크(113)와, 소화가스저장탱크(113)로부터 인출되어 배전반케이스(10) 내부로 노출되는 소화가스공급라인(114)과, 배전반케이스(10) 내부로 노출되도록 소화가스공급라인(114)의 선단에 연결되는 분사노즐(111)과, 소화가스공급라인(114)에 설치되며 제어유닛(90)에 의해 작동제어되어 소화가스의 분사를 제어하는 소화가스밸브(112)로 구성된다.The extinguishing device 110, the extinguishing gas is compressed and stored therein, the extinguishing gas storage tank 113 and the extinguishing gas storage tank 113 which is installed in the case (G2) installed on the upper surface of the switchboard case (10). Fire extinguishing gas supply line 114 is drawn from the exposed to the switchboard case 10 and the injection nozzle 111 connected to the tip of the digestion gas supply line 114 to be exposed to the switchboard case 10, and the fire extinguishing It is installed in the gas supply line 114 and is operated by the control unit 90 is composed of a fire gas valve 112 for controlling the injection of the fire gas.

이때, 상기 소화가스는 통상 소화기에 쓰이는 CO2가스로서, 배전반케이스(10) 내부에 화재가 발생하면, 배전반케이스(10) 내부의 산소를 최소화함과 동시에 배전반케이스(10) 내부 온도를 낮춰서, 배전반케이스(10) 내부의 화재가 확대되 는 것을 방지한다.At this time, the extinguishing gas is a CO 2 gas that is usually used in the fire extinguisher, when a fire occurs in the switchboard case 10, while minimizing the oxygen inside the switchboard case 10 and lowering the temperature inside the switchboard case 10, It prevents the fire inside the switchboard case 10 from expanding.

도 3은 본 발명에 따른 감전사고 방지형 지중전선 절연관의 작용을 나타낸 작동도로서, 도 3을 참조하여 본 발명에 따른 감전사고 방지형 지중전선 절연관의 작용을 설명하면 다음과 같다.3 is an operation diagram showing the action of the electric shock prevention ground wire insulated tube according to the present invention, the operation of the electric shock prevention ground wire insulated tube according to the present invention with reference to FIG.

상기 배전반(20)에 화재가 발생하면, 화재감지센서(80)는 제어유닛(90)으로 화재신호를 송신하고, 이를 수신한 제어유닛(90)은, 권취기구(75)의 구동모터(75b)를 구동하여 와이어(W)를 푼다. When a fire occurs in the switchboard 20, the fire detection sensor 80 transmits a fire signal to the control unit 90, and the control unit 90 that receives the fire signal is a drive motor 75b of the winding mechanism 75. ) To loosen the wire (W).

상기 와이어(W)가 풀어지면, 스프링(72)의 탄발력에 의해 타격부(73)가 좌측으로 이동하면서, 타격부(73)가 지중배관(30)을 수평으로 가로지른다. When the wire W is released, the striking portion 73 moves horizontally across the underground pipe 30 while the striking portion 73 moves to the left side by the elastic force of the spring 72.

이때, 상기 타격부(73)가 절단부(63)에 형성된 홈(h)에 닿으면서 절단부(63)를 좌측으로 밀고 들어가면, 연결대(60)의 제1연결부(61) 및 제2연결부(62)가 지지대(S)에 의해 지지되면서 상대적으로 취약한 연약부(f)가 끊어진다. 따라서, 배전반전력공급선(40)과 외부전력공급선(50)의 전기적 연결이 끊어진다.At this time, when the striking portion 73 pushes the cutting portion 63 to the left while touching the groove h formed in the cutting portion 63, the first connecting portion 61 and the second connecting portion 62 of the connecting table 60. While the support (S) is supported by the relatively weak fragile (f) is broken. Therefore, the electrical connection between the switchboard power supply line 40 and the external power supply line 50 is cut off.

이후, 계속적으로 진행하는 타격부(73)는 지중배관(30)의 삽입부(32)에 삽입되면서 지중배관(30)을 밀폐시켜 배전반(20)에 발생 된 화염이 지중배관(30)을 따라 더 이상 진행되지 않는다.Thereafter, the continuously blown portion 73 is inserted into the insertion portion 32 of the underground pipe 30 to seal the underground pipe 30 so that the flame generated in the switchboard 20 is along the underground pipe 30. It doesn't go any further.

한편, 배전반케이스(10)에 화재가 발생하면, 배전반케이스(10)에 설치된 화재감시센서(80)는 화재신호를 제어유닛(90)에 송출하고, 이를 수신한 제어유닛(90)이 경보장치(100)에 제어신호를 보내, 경보장치(100)가 화재발생을 외부로 나타내 도록 한다. 따라서, 상황실에 있는 관리자가 이를 확인하고 화재발생에 대해 즉각적으로 대처할 수 있다.On the other hand, if a fire occurs in the switchgear case 10, the fire monitoring sensor 80 installed in the switchgear case 10 sends a fire signal to the control unit 90, the control unit 90 receives this alarm device Send a control signal to (100), so that the alarm device 100 to indicate the fire outward. Therefore, the manager in the situation room can check this and respond immediately to the fire.

한편, 화재감지센서(80)로부터 화재신호를 수신한 제어유닛(90)은, 소화기구(110)의 소화가스밸브(112)를 개방한다. 따라서, 소화가스저장탱크(113) 내의 소화가스가 분사노즐을 통해 배전반케이스(10) 내부로 분사된다. On the other hand, the control unit 90 that receives the fire signal from the fire detection sensor 80 opens the extinguishing gas valve 112 of the fire extinguishing mechanism (110). Therefore, the extinguishing gas in the extinguishing gas storage tank 113 is injected into the switchboard case 10 through the spray nozzle.

상기 소화가스가 배전반케이스(10) 내부로 분사되면, 배전반케이스(10) 내부의 산소가 줄면서 상대적으로 소화가스의 비중이 커짐과 동시에 배전반케이스(10) 내부의 온도가 급강하하여 배전반케이스(10) 내부의 화염이 더 이상 번져나가지 않는다. When the extinguishing gas is injected into the switchboard case 10, the oxygen in the switchboard case 10 decreases and the specific gravity of the extinguishing gas increases, and at the same time, the temperature inside the switchboard case 10 drops sharply. The flame inside does not spread anymore.

상술한 바와 같이 본 발명에 따른 감전사고 방지형 지중전선 절연관은, 누전 또는 방화에 의해 배전반(20)이나 배전반케이스(10)에 화재가 발생하더도, 화염이 지중배관(30)을 따라 더 이상 진행되지 않지 않으며, 배전반(20)으로 전기가 공급되지 않아 감전사고가 발생하지 않는다. As described above, even if a fire occurs in the switchboard 20 or the switchboard case 10 due to an electric leakage or arson, the fire is further along the underground pipe 30. It does not progress any more, and no electricity is supplied to the switchboard 20 so that an electric shock accident does not occur.
