다수의 지중송전선 접속이 가능한 지중송전라인 연결장치{A device for connecting multiple underground transmission lines}A device for connecting multiple underground transmission lines

본 발명은 다수의 지중송전선 접속이 가능한 지중송전라인 연결장치에 관한 것이다.The present invention relates to an underground transmission line connection device capable of connecting a plurality of underground transmission lines.

발전소에서 생산된 전기는 지중송전선로를 통해 변전소로 송전된다.The electricity produced in the power plant is transmitted to the substation through an underground transmission line.

이중 지중을 통한 지중송전선로 시공방법은 직접 매설하는 방식과 관로를 만든 후 관로에 지중송전케이블을 수용하는 관로 방식, 지하에 전력구를 파고 전력구에 지중송전케이블을 포설하는 전력구 방식이 있다.There are two methods for constructing underground transmission lines through the underground: direct burial, a pipeline method in which the underground transmission cable is accommodated in the conduit after making a pipeline, and a power outlet method in which an electric power outlet is dug underground and the underground transmission cable is installed in the electric power outlet. .

이러한 방식 중 전력구 방식은 지중송전구간이 길면 중간에서 별도의 연결기구를 통해 지중송전선을 연결한다.Among these methods, if the underground transmission section is long, the underground transmission line is connected through a separate connection mechanism in the middle.

종래에는 지중송전선이 연결된 부분에서 평상시 누전이 발생할 경우, 이를 관리자에게 신속하게 알릴 수 없고, 누전된 지점으로 사람이 접근할 시 이에 대해 신속하게 경고할 수 없어, 지중송전선 연결부분에서 누전이 발생할 경우 매우 위험했다.Conventionally, when an electric leakage occurs in the part where the underground transmission line is connected, it is not possible to notify the manager quickly, and it is not possible to quickly warn about this when a person approaches the grounded point. It was very dangerous.

또한, 종래에는 화재가 발생할 시 이를 신속하게 진압할 수 없어 전력구 내에 대형화재가 발생하기 쉬웠고, 화재가 발생할 경우 전력구 내의 연기가 급속히 확산되어 안전지대 확보에 어려움이 있었다.Also, in the prior art, when a fire occurred, it was not possible to quickly extinguish it, so it was easy to cause a large fire in the electric power sphere.

상기 소방유닛(300)은 화재감지센서(310)와 제어부(320) 및 소화전(330)으로 구성된 것으로서, 본 실시 예의 경우 전력구(10)에 설치되어 화재를 감지해 신속하게 화재를 진압하는 역할을 한다.The fire fighting unit 300 is composed of a fire detection sensor 310, a control unit 320, and a fire hydrant 330. In this embodiment, the fire fighting unit 300 is installed in the electric power outlet 10 to detect a fire and quickly extinguish the fire. do

상기 화재감지센서(310)는 통상의 열 감지센서로, 전력구(10)의 내부 천정에 설치되어 화재시 발생되는 고온의 열을 열 감지해 이를 제어부(320)로 출력한다.The fire detection sensor 310 is a conventional heat sensor, installed on the inner ceiling of the electric power bulb 10 , detects high temperature heat generated during a fire, and outputs it to the control unit 320 .

상기 제어부(320)는 화재감지센서(310)로부터 화재감지신호를 전달받아 전력구(10)의 내부 천정에 설치되어 있는 소화전(330)의 분사밸브(331)로 소화전동작신호를 전달하여 분사밸브(331)를 통해 소화액이 전력구(10)의 내부로 분사될 수 있도록 하는 역할을 한다.The control unit 320 receives the fire detection signal from the fire detection sensor 310 and transmits the fire hydrant operation signal to the injection valve 331 of the hydrant 330 installed on the inner ceiling of the electric power outlet 10, It serves to allow the extinguishing liquid to be injected into the electric power outlet 10 through the 331 .

상기 소화전(330)은 외면이 단단한 철제용기로 되어 있고, 내부에는 소화약제와 압축공기 또는 높은 압력으로 액화된 불연성가스(질소, 이산화탄소, 할로겐가스)가 충진되며, 용기의 일측에는 내부에 충진된 소화약제와 불연성가스의 유출을 단속하는 분사밸브(331)가 설치된다.The fire hydrant 330 is made of an iron container with a hard outer surface, and a fire extinguishing agent and compressed air or non-combustible gas (nitrogen, carbon dioxide, halogen gas) liquefied at high pressure is filled inside, and one side of the container is filled inside An injection valve 331 for controlling the outflow of the extinguishing agent and non-combustible gas is installed.

본 실시 예의 경우, 제어부(320)로부터 소화전동작신호가 입력되면 분사밸브(331)의 입구는 개방되고, 이때 철제용기의 내부에 충진된 소화약제와 불연성가스가 내압에 의해 분사밸브(331)의 입구를 통해 전력구(10)의 내부로 분사되어 화재지역을 일순간 진압하게 되는 것이며, 이를 통해 화재발생에 따른 피해를 최소화할 수 있게 되는 것이다.In the case of this embodiment, when a fire hydrant operation signal is input from the control unit 320, the inlet of the injection valve 331 is opened, and at this time, the fire extinguishing agent and incombustible gas filled in the iron container are discharged by the internal pressure of the injection valve 331. It is sprayed into the inside of the electric power outlet 10 through the entrance to suppress the fire area in an instant, and through this, it is possible to minimize the damage caused by the fire.

따라서, 화재감지센서(310)로부터 화재감지신호를 전달받은 제어부(320)는 전력구(10)의 내부에 설치되어 있는 소화전(330)의 분사밸브(331)로 소화전동작신호를 전달하여 분사밸브(331)를 통해 소화액(소화약제와 불연성가스)이 전력구(10)의 내부로 분사될 수 있도록 함으로서 전력구(10)의 내부에 가설된 다른 지중송전선들이 전소(全燒) 되지 않도록 한다.Accordingly, the control unit 320 that has received the fire detection signal from the fire detection sensor 310 transmits the fire hydrant operation signal to the injection valve 331 of the hydrant 330 installed inside the electric power outlet 10 to provide the injection valve. By allowing the extinguishing liquid (extinguishing agent and non-combustible gas) to be injected into the electric power outlet 10 through 331 , other underground power lines installed in the electric power outlet 10 are not burned out.

그리고 이 지중송전선(L)들은 제2커넥터(220)를 매개로 전기적으로 상호 연결된다.And these underground transmission lines (L) are electrically interconnected via the second connector (220).

상기와 같이 지중송전선(L)이 가설된 상태에서 지중송전선(L)에 가설경로를 반대편으로 옮겨야 할 경우 점퍼유닛(100)과 전선연결유닛(200)을 매개로 신속하게 연결작업을 진행할 수 있다.As described above, when the underground transmission line (L) has to be moved to the opposite side of the construction path to the opposite side in the state where the underground transmission line (L) is erected, the connection work can be carried out quickly through the jumper unit 100 and the wire connection unit 200. .

이를 좀 더 구체적으로 설명하면, 먼저 전선연결유닛(200)의 트레이(210)로부터 조인트(230)가 서로 분리될 수 있게 체결수단(BN)을 분리해 준 다음 조인트(230)를 축핀을 중심으로 회전시켜준다.To explain this in more detail, first, the fastening means BN is separated from the tray 210 of the wire connection unit 200 so that the joint 230 can be separated from each other, and then the joint 230 is centered on the shaft pin. rotates it

그 다음 조인트(230)의 말단부를 점퍼유닛(100)의 일단부에 배치한 상태에서 분리했던 체결수단(BN)을 매개로 점퍼유닛(100)과 조인트(230)를 상호 결합한다.Then, the jumper unit 100 and the joint 230 are mutually coupled via the fastening means BN, which was separated in a state where the distal end of the joint 230 is disposed at one end of the jumper unit 100 .

상기와 같이 점퍼유닛(100)과 조인트(230)가 서로 연결되면, 점퍼유닛(100)의 제1커넥터(130)에는 제1단자(231)를 연결해 주고, 제2커넥터(220)에는 제2단자(232)를 연결하며, 제1커넥터(130)와 제2커넥터(220)는 전기적으로 상호 연결된다.When the jumper unit 100 and the joint 230 are connected to each other as described above, the first terminal 231 is connected to the first connector 130 of the jumper unit 100, and the second connector 220 is connected to the second connector. The terminal 232 is connected, and the first connector 130 and the second connector 220 are electrically interconnected.

이와 같이 지중송전선(L)에 가설경로를 쉽고 간편하게 옮겨 줄 수 있는 이점이 있다.As described above, there is an advantage that the temporary route can be easily and conveniently transferred to the underground transmission line (L).

본 발명은 기재된 구체적인 실시 예에 대해서만 상세히 설명되었지만 본 발명의 기술사상범위 내에서 다양하게 변형 및 수정할 수 있음은 당업자에 있어서 당연한 것이며, 이러한 변형 및 수정이 첨부된 특허청구범위에 속함은 당연한 것이다.Although the present invention has been described in detail only with respect to the specific embodiments described, it is natural for those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention, and it is natural that such variations and modifications belong to the appended claims.
