지중전선 보호용 배전반{Underground Electroic Line Protection For Distributing Case}Underground Electroic Line Protection For Distributing Case

본 발명은, 지중에 매설되어 보호되는 지중선로를 효과적으로 보호하도록 함과 동시에 단락 및 누전과 같은 전기안전사고의 발생 가능성을 최소화할 수 있도록 된 지중전선 보호용 배전반에 관한 것이다.The present invention relates to an underground power line switchgear capable of effectively protecting underground lines that are buried and protected in the ground, and at the same time minimizing the possibility of occurrence of electrical safety accidents such as short circuits and short circuits.

일반적으로 각 가정이나 사무실 및 대규모의 공장 등에서 사용되는 전기는 각 지역별로 설비되어 있는 변전소를 통해 전기를 공급받게 되는데, 이러한 변전소는 전압이나 전류의 변성 및 전력의 배분을 목적으로 설치되는 것으로, 발전소에서 생산된 전력을 송전선로를 통해 사용자에게 보내 주게 된다.In general, the electricity used in each home, office, and large-scale factories is supplied with electricity through substations installed in each region. These substations are installed for the purpose of changing voltage or current and distributing power. The power generated by is sent to the user through the transmission line.

상기 변전소는 대체로 지상에 설비되게 되는데, 이러한 변전소의 경우 고압의 전류를 이송시켜 주어야 하는바 고압전선이 외부로 노출되어 있는 것이 대부분이고, 외부로 노출된 고압전선은 외부간섭으로 인한 누전 및 합선이 유발되기 쉬우며, 어지럽게 가설된 고압전선으로 인해 주변의 경관을 해치 등의 문제가 있어 지하에 고압전선을 설치하게 되었다.The substation is generally installed on the ground, in the case of such a substation is to transfer the high-voltage current is a high voltage wire is mostly exposed to the outside, the high-voltage wire exposed to the outside is a short circuit and short circuit due to external interference It is easy to be induced, and because of the dizzying hypothesis of high voltage cables, there is a problem such as hatching the surrounding landscape.

상기와 같이 지하에 고압의 전선을 설치하는 경우 외부로 노출이 되지 않아 외부간섭에 따른 문제 및 주변경관 해치는 등의 문제는 해소되었지만, 이를 지상에 설치된 배전함에 연결한 경우 각종 외적인 요인으로 인하여 도선에 일부분가 끊어져 전기합선사고를 일어나거나 또는 노후로 인해 보호기능을 상실한 피복선의 내측으로 침투수가 유입되어 전류가 흐르는 도선과 접촉됨으로써, 누전 및 합선에 따른 화재가 발생되어 내부에 배선된 지중전선이 일시에 전부 전소 되는 등의 문제가 있어 화재를 신속하게 진압할 수 있는 방안에 대한 연구도 활발히 진행되고 있다.In case of installing the high voltage wire in the basement as mentioned above, the problems such as external interference and harming the surrounding landscape are solved because they are not exposed to the outside, but when it is connected to the distribution box installed on the ground, Partial breakage may cause an electrical short circuit or penetrate into the inside of the insulated wire that has lost its protective function due to aging and contact with current flowing wires, resulting in a short circuit and a short circuit. As there is a problem such as all burned down, research is being actively conducted on measures to extinguish a fire quickly.

한편, 지상에 설치된 배전함에 연결한 경우 지진이 발생되면 지면이 좌우 뿐만 아니라 상하로 진동하게 되는데, 이때 상하로 진동되는 지진에 의해 배전함에 연결된 전선의 배선부위에 고정상태가 해제되거나 또는 반복적인 진동에 따른 전선의 자중에 의해 전선이 단선되는 문제가 있었다.On the other hand, when connected to a distribution box installed on the ground, when an earthquake occurs, the ground vibrates up and down, as well as up and down, at which time the fixed state is released or repeated vibrations in the wiring part of the wire connected to the distribution box by the earthquake that vibrates up and down There was a problem that the wire is disconnected by the weight of the wire according to.

In order to solve this problem, research was actively conducted.

Fire hydrants 90 are provided, respectively, as shown in FIG.

상기 지지플레이트(20)에는 화재감지센서(70)가 설치되는데, 본 실시 예의 경우 상기 화재감지센서(70)는 통상의 열 감지센서로, 쥐와 같은 설치류에 의해 지중전선(L)이 손상되어 도선에 일부분가 끊어져 전기합선에 따른 화재가 발생되거나 또는 노후로 인해 보호기능을 상실한 피복선의 내측으로 침투수가 유입되어 전류가 흐르는 도선과 접촉되므로서 누전 및 합선에 따른 화재가 일어나는 경우, 화재시 발생되는 고온의 열을 열 감지센서 즉, 화재감지센서(70)가 이를 감지하여 제어부(80)로 화재감지신호를 전달하게 된다.A fire detection sensor 70 is installed on the support plate 20. In the present embodiment, the fire detection sensor 70 is a general heat detection sensor, and the underground wire L is damaged by rodents such as rats. Fire occurs due to short circuit and short circuit due to breakage of electric wires and fire due to electric short circuit, or infiltration water flows into the inside of the insulated wire which loses protection function due to aging. The heat detection sensor, that is, the fire detection sensor 70 detects the heat of high temperature, and transmits the fire detection signal to the controller 80.

따라서, 상기 화재감지센서(70)로부터 화재감지신호를 전달받은 제어부(80)는 지지플레이트(20)의 저면에 배치되어 있는 소화전(90)의 분사밸브(91)로 소화전동작신호를 전달하여 분사밸브(91)를 통해 소화액이 지중전선(L) 및 지중전선(L)이 실장된 지중관(P)의 내부로 분사되며, 이를 도 5와 같이 도시하였다.Therefore, the controller 80 receiving the fire detection signal from the fire detection sensor 70 transmits the hydrant operation signal to the injection valve 91 of the hydrant 90 disposed on the bottom surface of the support plate 20 for injection. Through the valve 91, the digestive fluid is injected into the underground pipe (P) on which the underground wire (L) and the underground wire (L) are mounted, as shown in FIG.

상기 소화전(90)은, 외면이 단단한 철제용기로 되어 있고, 내부에는 소화약 제와 압축공기 또는 높은 압력으로 액화된 불연성가스(질소, 이산화탄소, 할로겐가스)가 충진되며, 용기의 일측에는 내부에 충진된 소화약제와 불연성가스의 유출을 단속하는 분사밸브(91)가 설치된다.The fire hydrant 90 is made of a steel container with a hard outer surface, and is filled with a fire extinguishing agent and compressed air or a non-combustible gas (nitrogen, carbon dioxide, halogen gas) liquefied at high pressure, and on one side of the container therein. An injection valve 91 for controlling the outflow of the filled extinguishing agent and non-combustible gas is installed.

본 실시 예의 경우, 상기 제어부(80)로부터 소화전동작신호가 입력되면 분사밸브(91)의 입구는 개방되고, 이때 철제용기의 내부에 충진된 소화약제와 불연성가스가 내압에 의해 분사밸브(91)의 입구를 통해 지중전선(L) 및 지중전선(L)이 실장된 지중관(P)의 내부로 분사되어 화재지역을 일순간 진압되록 함으로서, 이를 통해 화재발생에 따른 피해를 최소화할 수 있게 되는 것이다.In the present embodiment, when the hydrant operation signal is input from the controller 80, the inlet of the injection valve 91 is opened, and at this time, the extinguishing agent and non-combustible gas filled in the steel container are injected by the internal pressure. Through the entrance of the underground cable (L) and underground cable (L) is injected into the interior of the underground pipe (P) mounted to suppress the fire zone for a moment, thereby minimizing the damage caused by the fire. .

위와 같은 구성으로 이루어진 본 발명의 작동관계를 설명하면 다음과 같다.Referring to the operational relationship of the present invention made of the above configuration as follows.

우선, 배전함(10)의 받침대(11) 상부에 설치된 지지플레이트(20)의 설치공(21) 내주면에 지중전선장착부재(40)를 배치시켜 주고, 지중전선장착부재(40)의 체결부(43)를 체결수단(예, 앵커볼트)을 매개로 설치고정한 상태에서 외면에 환형링(50)이 감착된 지중전선(L)을 지중전선장착부재(40)의 하부에 위치시켜 주며, 이를 도 3a에 도시된 바와 같이 도시하였다.First, the underground wire mounting member 40 is disposed on the inner circumferential surface of the installation hole 21 of the support plate 20 installed above the pedestal 11 of the distribution box 10, and the fastening portion of the underground wire mounting member 40 is formed. 43) in the state of fixing the fastening means (e.g. anchor bolts) through the installation of the underground wire (L) in which the annular ring 50 is wound on the outer surface of the underground wire mounting member (40), As shown in 3a.

상기와 같이 지중전선(L)을 위치시켜 준 상태에서 지중전선(L)을 상방으로 밀어 주게 되면, 지중전선장착부재(40)의 안내부(41d)를 따라 지중전선(L)이 삽입되게 되고, 이때 밀려들어 오는 지중전선(L)에 의해 다수개의 탄지편(41-1)은 방사형을 이루며 외향으로 벌어지게 되며, 이를 도 3b와 같이 도시하였다.When the underground wire L is pushed upward while the underground wire L is positioned as described above, the underground wire L is inserted along the guide portion 41d of the underground wire mounting member 40. In this case, the plurality of bombardment pieces 41-1 are radially spread outwardly by the underground wire L, which is pushed inward, as shown in FIG. 3B.

그리고, 상기와 같이 지중전선(L)을 더욱 힘을 가해 상방으로 밀어주게 되 면, 비로소 지중전선(L)의 외면에 감착된 환형링(50)이 지중전선소켓(41)의 억류부(41b)와 결합되어 고정되고, 외향으로 벌어져 있던 다수개의 탄지편(41-1)은 탄성 복원력에 의해 원상태로 회복되게 된다.Then, when the above ground wire (L) is further pushed upward to push upward, the annular ring 50, which is attached to the outer surface of the underground wire (L) until the detention portion (41b) of the underground wire socket 41 ) Is fixed in combination with, and the plurality of outgoing tangy pieces (41-1) is recovered to its original state by the elastic restoring force.

따라서, 상기와 같이 결합시켜 준 상태에서 작업자는 지중전선장착부재(40)의 연결바(42) 사이로 손을 집어넣고 지중전선소켓(41)의 고정부(41c) 외면을 고정부재(60)를 감착한 상태에서 지중전선(L)이 하방으로 낙하되지 않을 정도로 고정부재(60)를 압박고정하며, 고정이 완료된 이후에는 함체(1)의 내부로 인입된 지중전선(L)을 목적에 맞게 배선연결하면 된다. 상기와 같은 과정을 도 3c와 같이 도시하였다. Therefore, the worker puts his hand between the connection bar 42 of the underground wire mounting member 40 in the state that is coupled as described above and the fixing member 60 to the outer surface of the fixing portion 41c of the underground wire socket 41. In the attached state, the underground wire L is fixed to the fixing member 60 so that the underground wire L does not fall downward, and after the fixing is completed, the underground wire L introduced into the enclosure 1 is wired according to the purpose. Just plug it in. The same process as shown in Figure 3c.

이와 같이, 지지플레이트(20)의 설치공(21) 내주면에 지중전선장착부재(40)를 설치하여 줌으로서, 지중전선(L)을 쉽고 간편 고정할 수 있고, 설치작업이 비교적 쉬어 작업의 편의성을 향상시켜 줄 수 있으며, 설치시간을 획기적으로 줄일 수 있어 작업에 따른 비용절약 및 넓은 지역을 신속하게 설치할 수 있다.In this way, by installing the underground wire mounting member 40 on the inner circumferential surface of the installation hole 21 of the support plate 20, the underground wire L can be easily and simply fixed, and the installation work is relatively easy, and thus the convenience of work. In addition, the installation time can be drastically reduced, thereby reducing the work cost and installing a large area quickly.

한편, 상기와 같이 설치된 상태에서 지진이 발생하게 되면 지면이 좌우 뿐만 아니라 상하로도 심하게 진동되어 지중전선장착부재(30)를 매개로 지지플레이트(10)에 설치된 지중전선(L) 역시 상하로 진동하게 된다.On the other hand, when the earthquake occurs in the above-described state, the ground vibrates violently up and down as well as up and down, and the underground wire L installed on the support plate 10 via the underground wire mounting member 30 also vibrates up and down. Done.

이와 같이, 지진발생으로 인한 상하진동시 지중전선(L)이 하방으로 힘이 가해지게 되면, 이를 받침대(1-1)와 지지플레이트(10) 사이에 배치된 완충부재(20)가 압축 및 복원을 반복하면서 진동을 흡수하게 되고, 이로 인하여 지중전선(L)에 가 해지는 힘은 완충부재(20)에 의해 힘이 분산되거나 상쇄되어 반복적인 상하진동으로 인한 지중전선(L)의 단선을 방지할 수 있도록 함으로서, 지진으로 인한 2차 피해를 미연에 차단할 수 있게 되는 것이며, 이를 도 4와 같이 도시하였다.As such, when the underground wire L is applied downward when the earthquake vibrates due to the earthquake, the buffer member 20 disposed between the pedestal 1-1 and the support plate 10 is compressed and restored. Absorption is repeated while absorbing the vibration, thereby the force applied to the underground wire (L) is dispersed or offset by the shock absorbing member 20 to prevent the disconnection of the underground wire (L) due to repeated vertical vibration By doing so, it is possible to block the secondary damage caused by the earthquake in advance, as shown in FIG.

또한, 상기와 같이 설치된 상태에서 쥐와 같은 설치류에 의해 지중전선(L)이 손상되어 도선에 일부분가 끊어져 전기합선에 따른 화재가 발생하거나 또는 노후로 인해 보호기능을 상실한 피복선의 내측으로 침투수가 유입되어 전류가 흐르는 도선과 접촉되므로서 누전 및 합선에 따른 화재가 일어나는 경우, 화재감지센서(70)가 화재시 유발되는 열을 감지하여 제어부(80)로 화재감지신호를 전달하고, 화재감지센서(70)로부터 화재감지신호를 전달받은 제어부(80)는 지지플레이트(20)의 하부에 설치되어 있는 소화전(90)의 분사밸브(91)로 소화전동작신호를 전달하여 분사밸브(91)을 통해 소화액이 지중전선(L) 및 지중전선(L)이 실장된 지중관(P)의 내부로 분사하게 된다.In addition, the underground wire (L) is damaged by rodents such as rats in the above-described state, and a part of the ground wire is broken, causing a fire due to an electric short circuit or infiltration water flowing into the inner side of the coated wire which has lost its protective function due to aging. When a fire occurs due to a short circuit and a short circuit due to contact with a current flowing through the current, the fire detection sensor 70 detects heat generated during the fire and transmits a fire detection signal to the controller 80, and the fire detection sensor 70. Fire control signal received from the control unit 80 transmits the hydrant operation signal to the injection valve 91 of the hydrant 90 is installed in the lower portion of the support plate 20 to extinguish the liquid through the injection valve 91 Underground wire (L) and underground wire (L) is injected into the interior of the underground pipe (P) mounted.

이를 좀 더 상세히 설명하면, 상기 제어부(80)로부터 소화전동작신호가 입력되면 분사밸브(91) 입구는 개방되고, 이때 철제용기의 내부에 충진된 소화약제와 불연성가스는 내압에 의해 분사밸브(91) 입구를 통해 지중전선(L) 및 지중전선(L)이 실장된 지중관(P)의 내부로 분사되어 화재지역을 일순간 진압하게 되는 것이며, 이를 도 6과 같이 도시하였다.In more detail, when the hydrant operation signal is input from the controller 80, the inlet of the injection valve 91 is opened, and the extinguishing agent and non-combustible gas filled in the steel container are injected by the internal pressure. ), The underground wire (L) and the underground wire (L) is injected into the interior of the underground pipe (P) mounted through the inlet to extinguish the fire zone for a moment, as shown in FIG.
