특고압 지중전선 배전대{The High Voltage Underground Electroic Line Of Frame}The High Voltage Underground Electroic Line Of Frame

본 발명은, 지중전선의 합선 및 누전가능성을 줄일 수 있도록 하는 한편, 라인의 폐쇄 또는 고장으로 인한 전원공급의 발생가능성을 크게 줄일 수 있는 특고압 지중전선 배전대에 관한 것이다.The present invention relates to an extra-high voltage underground switchboard that can reduce the possibility of short circuits and short circuits in underground cables, and can greatly reduce the possibility of power supply due to closing or failure of the lines.

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 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.When installing high voltage wires in the basement as described above, problems such as external interference and surrounding landscape harm are resolved because they are not exposed to the outside, but when connected to the distribution box installed on the ground, when the earthquake occurs, the ground is left and right In addition, there is a problem that the up and down oscillation, in which the fixed state is released to the wiring portion of the wire connected to the distribution box by the earthquake oscillating up and down, or the wire is disconnected by the weight of the wire due to repetitive vibration.

또한, 상기와 같이 지상에 설치된 배전함에 전선을 연결하고자 하는 경우에는 지중에 매설된 전선을 인출하여 배선연결하기가 상당히 힘들고 번거로울 뿐만 아니라, 지중전선을 마땅히 고정할 만한 수단이 마련되어 있지 않아 배전함에 직접 연결할 경우 자중을 이기지 못한 지중전선이 지중관의 내부로 낙하되어 연결상태(고정상태)가 해제됨으로써, 전원을 필요로 하는 각 가정이나 사무실 및 대규모의 공장 등에 전기를 공급할 수 없게 되는 문제가 빈번히 발생하는 바, 이와 같은 문제를 해소하기 위한 연구가 활발히 진행 중이였다.In addition, if you want to connect the wires in the distribution box installed on the ground as described above, it is very difficult and cumbersome to draw and connect the wires buried in the ground, and there is no means for fixing the underground wires directly, so In case of connection, underground cable which could not overcome its own weight falls into the underground pipe, and the connection state (fixed state) is released, which frequently causes problems such as inability to supply electricity to homes, offices and large factories that require power. In order to solve this problem, research was actively conducted.

본 발명은 상기와 같은 문제를 해소하기 위하여 안출된 것으로서, 받침대와 지지플레이트 사이에 배치된 완충부재를 통해 지진으로 인한 상하진동시 이를 분산 및 상쇄되도록 하여, 지진으로 인한 2차 피해 즉, 지중전선의 단선 및 화재와 같은 전기안전사고를 미연에 차단하고, 지중전선을 쉽고 간편 고정할 수 있어 작업의 편의성을 향상시켜 줄 수 있는 특고압 지중전선 배전대를 제공하려는데 그 목적이 있다. The present invention has been devised to solve the above problems, by dispersing and offset the vertical vibration due to the earthquake through the buffer member disposed between the pedestal and the support plate, the secondary damage caused by the earthquake, that is underground wire The purpose of the present invention is to provide an extra-high voltage underground cable switchboard that can block electrical safety accidents such as disconnection and fire in advance and can easily and easily fix underground cables.

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, 함체(1)의 받침대(1-1) 상부에 설치된 지지플레이트(10)의 설치공(11) 내주면에 지중전선장착부재(30)를 배치시켜 주고, 지중전선장착부재(30)의 체결부(33)를 체결수단(예, 엥커볼트)을 매개로 설치고정한 상태에서 외면에 환형링(40)이 감착된 지중전선(L)을 지중전선장착부재(30)의 하부에 위치시켜 주며, 이를 도 3a에 도시된 바와 같이 도시하였다.First, the underground wire mounting member 30 is disposed on the inner circumferential surface of the installation hole 11 of the support plate 10 installed above the pedestal 1-1 of the enclosure 1, and the underground wire mounting member 30 is fastened. In the state in which the fixing part 33 is installed and fixed by means of fastening means (for example, anchor bolts), the underground wire L having the annular ring 40 wound on the outer surface thereof is positioned under the underground wire mounting member 30. This is shown as shown in FIG. 3A.

상기와 같이 지중전선(L)을 위치시켜 준 상태에서 지중전선(L)을 상방으로 밀어 주게 되면, 지중전선장착부재(30)의 안내부(31d)를 따라 지중전선(L)이 삽입되게 되고, 이때 밀려들어 오는 지중전선(L)에 의해 다수개의 탄지편(31-1)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 31d of the underground wire mounting member 30. In this case, the plurality of bombardment pieces 31-1 are radially spread outward by the underground wire L, which is pushed inwardly, as shown in FIG. 3B.

그리고, 상기와 같이 지중전선(L)을 더욱 힘을 가해 상방으로 밀어주게 되면, 비로소 지중전선(L)의 외면에 감착된 환형링(40)이 지중전선소켓(31)의 억류부(31b)와 결합되어 고정되고, 외향으로 벌어져 있던 다수개의 탄지편(31-1)은 탄성 복원력에 의해 원상태로 회복되게 된다.Then, when the ground wire (L) is pushed upward by applying more force as described above, the annular ring 40, which is attached to the outer surface of the underground wire (L), is detained part (31b) of the underground wire socket (31). It is fixed in combination with the plurality of outwardly spreading the fingertips 31-1 is restored to its original state by the elastic restoring force.

따라서, 상기와 같이 결합시켜 준 상태에서 작업자는 지중전선장착부재(30)의 연결바(32) 사이로 손을 집어넣고 지중전선소켓(31)의 고정부(31c) 외면을 고정부재(50)를 감착한 상태에서 지중전선(L)이 하방으로 낙하되지 않을 정도로 고정부재(50)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 32 of the underground wire mounting member 30 in the state that is coupled as described above and the fixing member 50 to the outer surface of the fixing part 31c of the underground wire socket 31. In the squeezed state, pressure fixing member 50 is fixed so that the underground wire L does not fall downward, and after the fixing is completed, the underground wire L introduced into the interior of the enclosure 1 is wired according to the purpose. Just plug it in. The same process as shown in Figure 3c.

이와 같이, 지지플레이트(10)의 설치공(11) 내주면에 지중전선장착부재(30) 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 30 on the inner circumferential surface of the installation hole 11 of the support plate 10, the underground wire L can be easily and simply fixed, and the installation work is relatively easy, thus making the work easier. 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 가해지는 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 buffer 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.
