Description

누전 경고 기능을 구비한 안전성 탑재 지중배전 연결기구{Equipment For Connecting Underground Distribution Lines} Safety Mounted Underground Distribution Lines with Earth Leakage Warning Function {Equipment For Connecting Underground Distribution Lines}

본 발명은 누전 경고 기능을 구비한 안전성 탑재 지중배전 연결기구에 관한 것이다.The present invention relates to a safety-mounted underground distribution connection mechanism having an earth leakage warning function.

지중배전선로는 도시미관을 확보하기 위한 지역 또는 가공선로 시설이 기술적으로 불가능하고, 유지보수가 곤란한 지역에 주로 설치되며, 특히 가공선이 집중되어 있는 변전소 인출 부근, 부하밀도가 높고 고층빌딩으로서 공급 여력을 확보하는데 다회선 구성이 기술적으로 곤란한 개소 등에 설치된다Underground distribution lines are mainly installed in areas where overhead line facilities are technically impossible and difficult to maintain to ensure urban aesthetics. It is installed in places where multi-line configuration is technically difficult to secure

이러한 지중배전선로는 도 1과 같이 전력구(1) 내벽에 설치되는 트레이(2)에 의해 배선이 이루어진다.The underground distribution line is wired by the tray 2 installed on the inner wall of the electric power outlet 1 as shown in FIG. 1 .

그러나, 종래의 지중배전선로는 누전이 발생할 시 이를 전력구 통행자에게 알릴 수 없어, 누전 발생지점을 통과하는 통행자가 감전사고의 위험에 심각하게 노출되었다.However, the conventional underground distribution line cannot notify the passers-by when an electric leakage occurs, and thus the passers-by passing through the electric leakage point are seriously exposed to the risk of electric shock.

또한, 종래의 지중배전선로는 지중배전선 지지장치(대한민국 등록특허공보 제10-2227021호; 지중 배전용 케이브 지지장치)와 같은 수단을 매개로 설치된다.In addition, the conventional underground distribution line is installed through the same means as the underground distribution line support device (Korean Patent Registration No. 10-2227021; underground distribution cable support device).

그러나, 종래에는 다양한 방향으로 지중배전선을 연결하여, 다양한 방향으로 지중배전선로가 분기되도록 하는데 어려움이 있었다.However, in the prior art, it has been difficult to connect the underground distribution lines in various directions so that the underground distribution lines are branched in various directions.

또한, 종래에는 지중배전선 지지를 위한 지지대가 상방으로 회전하기 용이하여 지중배전선이 이탈하기 쉬웠고(대한민국 등록특허공보 제10-2227021호의 도 2 참조), 이를 개선하기 위해서는 지중배전선 지지를 위한 지지대의 구성이 복잡해지는(대한민국 등록특허공보 제10-2227021호의 도 4 참조) 문제가 발생하였다.In addition, in the prior art, the support for supporting the underground distribution line was easy to rotate upward, so that the underground distribution line was easy to break away (refer to FIG. 2 of Korean Patent Publication No. 10-2227021). In order to improve this, the configuration of the support for supporting the underground distribution line This complexity (refer to FIG. 4 of Korean Patent Publication No. 10-2227021) occurred.

도 6은 본 발명에서 누전경고 과정을 설명하기 위한 도면이고, 도 7은 본 발명에서 지지기구 설치 과정을 설명하기 위한 도면(지지기구는 가상선으로 표현)으로, 도 6 및 도 7를 참조하여 본 발명의 작용을 설명하면 다음과 같다.Figure 6 is a view for explaining the earth leakage warning process in the present invention, Figure 7 is a view for explaining the installation process of the support mechanism in the present invention (the support mechanism is represented by a virtual line), with reference to Figures 6 and 7 The operation of the present invention will be described as follows.

우선, 본 발명이 설치된 상태에서 커넥팅기구(50)에서 누전이 발생하면, 누전감지센서(30)는 누전감지신호를 출력하고, 누전감지신호를 수신한 경고등(40)은 도 6과 같이 주변으로 누전 경고 빛을 방출한다.First, when an earth leakage occurs in the connecting mechanism 50 in the state in which the present invention is installed, the earth leakage detection sensor 30 outputs an earth leakage detection signal, and the warning light 40 that has received the earth leakage detection signal turns to the surroundings as shown in FIG. Emit a short circuit warning light.

여기서, 지지기구(20) 설치 과정을 살펴보면 다음과 같다.Here, the support mechanism 20 installation process will be described as follows.

고정브라켓(10)이 전력구(C)에 설치된 상태에서, 지지기구(20)를 고정브라켓(10)의 후방에 경사지게 위치시킨 후, 지지기구(20)를 전방으로 이동시켜 도 7(a)와 같이 걸림체(23)가 고정브라켓(10)의 삽입홀(11a)을 통과하면서 기준회전축(22)이 고정브라켓(10)의 삽입홀(11a)에 삽입되도록 한다. In a state in which the fixing bracket 10 is installed in the electric power tool C, the support mechanism 20 is inclined at the rear of the fixing bracket 10, and then the support mechanism 20 is moved forward to see Fig. 7 (a). As shown, while the locking body 23 passes through the insertion hole 11a of the fixing bracket 10 , the reference rotation shaft 22 is inserted into the insertion hole 11a of the fixing bracket 10 .

이어서, 지지기구(20)를 회전시켜(도 7a의 화살표 방향 참조) 지지기구(20)를 수평 방향으로 위치시키면, 도 7(b)와 같이 걸림체(23)가 시계 방향으로 회전하면서 이동걸림축(24)이 고정브라켓(10)의 가이드홀(11b)를 따라 시계 방향으로 회전한다.Then, when the support mechanism 20 is rotated (refer to the direction of the arrow in FIG. 7a) to position the support mechanism 20 in the horizontal direction, the locking body 23 rotates clockwise as shown in FIG. The shaft 24 rotates clockwise along the guide hole 11b of the fixing bracket 10 .

이후, 지지기구(20)를 하방으로 이동하면(도 7b의 화살표 방향 참조), 도 7(c)와 같이 지지기구(20)가 위치하게 된다.Thereafter, when the support mechanism 20 is moved downward (refer to the direction of the arrow in FIG. 7B ), the support mechanism 20 is positioned as shown in FIG. 7C .

그러면, 지지기구(20)는, 걸림체(23)에 의해 후방으로의 이동이 제한되고, 기준회전축(22)에 의해 우방으로의 이동이 제한되며, 이동걸림축(24)에 의해 반시계 방향으로의 회전이 제한되고, 지지판(25)에 의해 시계 방향으로의 회전이 제한된다. 이때 지지판(25)은, 지지기구(20)가 시계 방향으로 회전하는 것을 제한하여, 지중배전선이 접속된 커넥팅기구(50)가 지지기구(20)에 안착될 시 충분한 지지력을 제공한다.Then, the support mechanism 20 is restricted from moving backward by the locking body 23 , the movement to the right is restricted by the reference rotation shaft 22 , and counterclockwise by the locking shaft 24 . rotation is restricted, and rotation in the clockwise direction is restricted by the support plate 25 . At this time, the support plate 25 limits the rotation of the support mechanism 20 in a clockwise direction, and provides sufficient support force when the connecting mechanism 50 to which the underground distribution line is connected is seated on the support mechanism 20 .

한편, 본 발명에서는 지중배전선의 설치 환경에 따라 상기와 같은 방식으로 다수의 지지기구(20)를 설치하여, 도 2과 같이 다수의 지지기구(20)가 위치를 서로 달리하여 배치되도록 할 수 있다.On the other hand, in the present invention, a plurality of support mechanisms 20 are installed in the same manner as described above according to the installation environment of the underground distribution line, so that the plurality of support mechanisms 20 are arranged at different positions as shown in FIG. 2 . .

다음으로, 지중배전선을 커넥팅기구(50)의 접속구(52)에 접속하여, 지중배전선 간을 연결하면, 지중배전선 간에 전기적 접속이 안정적으로 이루어지면서 지중배전선이 안정적으로 지지된다. 이때 지중배전선은 다양한 방향으로 분기되게 설치될 수 있다. Next, when the underground distribution line is connected to the connection port 52 of the connecting mechanism 50 and the underground distribution lines are connected, the underground distribution line is stably supported while the electrical connection between the underground distribution lines is stably made. In this case, the underground distribution line may be installed to branch in various directions.

상술한 바와 같은 본 발명은, 커넥팅기구(50)에 누전이 발생하면 주변에 경고를 하여, 커넥팅기구(50) 주변에 위치한 사람이 감전사고에 노출되는 것을 방지하는 효과가 있다.The present invention as described above has the effect of preventing a person located in the vicinity of the connecting mechanism 50 from being exposed to an electric shock accident by giving a warning to the surroundings when a short circuit occurs in the connecting mechanism 50 .

또한, 본 발명은 지중배전 전기라인이 다양한 방향으로 분기되도록 지중배전선을 연결할 수 있는 효과가 있다. In addition, the present invention has an effect that the underground distribution lines can be connected so that the underground distribution electric lines branch in various directions.

또한, 본 발명은, 간단한 구조로 이루어져 손쉬운 작업으로 지지기구(20)가 반시계 방향으로 회전하는 것을 방지할 수 있는 효과가 있다. 즉 지지기구(20)를 안정적으로 위치고정시킬 수 있는 효과가 있다.In addition, the present invention has an effect that can prevent the support mechanism 20 from rotating in the counterclockwise direction with an easy operation made of a simple structure. That is, there is an effect of stably fixing the position of the support mechanism 20 .

또한, 본 발명은, 지지기구(20)의 좌우 위치를 조절하여, 지중배전선의 설치 환경에 따라 지중배전선 설치위치를 다양화하여 설치할 수 있으며, 이때 지지기구(20)의 위치이동에 따라 지지판(25)의 위치를 쉽게 조절하여, 지지기구(20)의 위치고정을 안정적으로 할 수 있는 효과가 있다.In addition, in the present invention, by adjusting the left and right positions of the support mechanism 20, the installation position of the underground distribution line can be diversified and installed according to the installation environment of the underground distribution line, and at this time, according to the position movement of the support mechanism 20, the support plate ( 25), there is an effect of stably fixing the position of the support mechanism 20 by easily adjusting the position.
