본 발명은 전선의 합선방지구조에 관한 것으로, 특히 피복의 파손을 감지하여 전선간의 합선을 미연에 방지할 수 있는 공동주택에 배선된 전선의 합선방지구조에 관한 것이다.The present invention relates to a short circuit prevention structure of an electric wire, and more particularly, to a short circuit prevention structure of an electric wire wired in a multi-unit house which can detect a breakage of the coating and prevent short circuit between the electric wires.

주지된 바와 같이 종래의 공동주택에 배선되는 전선은, 벽체나, 기둥, 천정이나 바닥 등의 건축물에 설치되어, 외부 전력을 전기장치로 전달하는 수단이다. 그런데, 전선의 피복이 외력에 의해 파손을 입거나 노화로 인해 벗겨지면 해당 피복의 내부에 설치된 전력선과, 피복이 손상된 또 다른 전력선과 서로 맞닿아 합선의 위험이 있다. 또한, 피복의 손상 부위에 우수가 유입될 수 있고, 이로 인한 누전 또는 감전이 발생할 수 있는 문제도 있었다.As is well known, electric wires that are wired in a conventional multi-family house are installed in buildings such as walls, columns, ceilings, and floors, and are means for transmitting external electric power to electric devices. However, when the covering of the wire is damaged by external force or peeled off due to aging, there is a danger of short circuit due to contact with the power line installed inside the covering and another power line with the covering damaged. In addition, rainwater may flow into the damaged part of the coating, and there may be a problem in which a short circuit or an electric shock may occur.

또한, 실내에는 각종 전선이 다수 개 설치되므로 어느 전선의 피복이 손상되어 합선의 위험을 안고 있는지 알 수 없어서, 해당 전선뿐 아니라 정상적인 전선 모두를 교체하게 되어 경제적으로도 비효율적이었다. In addition, since a number of various wires are installed indoors, it is not economically inefficient to replace all the normal wires as well as the wires because it is impossible to know which wires are damaged and the risk of a short circuit.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 파손된 피 복을 손쉽게 확인하여 효율적인 전선관리를 가능하게 하는 공동주택에 배선된 전선의 합선방지구조를 제공하는 것을 그 목적으로 한다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a short circuit prevention structure of the wires wired in the apartment house to enable efficient wire management by easily identifying the damaged coating.

상기 목적을 달성하기 위해 본 발명은, 둘레부에 가스가 주입되어 밀폐되는 챔버를 갖는 고무재질의 관형상으로, 외부 전선으로부터 분전된 다수의 전력선을 각각 내설하여 실내벽체에 배선되는 피복과; 피복의 챔버내에 가스의 압력을 측정하여 기준압력 이하가 되면 고유한 지정신호를 발신하는 압력센서와; 피복과 짝을 이루도록 피복에 상응하는 갯수로 누전차단기에 설치되는 LED; 압력센서의 지정신호를 수신하여 해당 피복을 확인하고, 짝을 이루는 LED를 점등시키는 제어부로 이루어진 구조이다.In order to achieve the above object, the present invention is a rubber-like tubular shape having a chamber in which gas is injected into the periphery, the coating is installed on the interior wall by internally installing a plurality of power lines distributed from an external electric wire; A pressure sensor that measures the pressure of the gas in the chamber of the coating and transmits a unique designated signal when the pressure falls below the reference pressure; LEDs installed in the circuit breaker in the number corresponding to the coating to mate with the coating; Receiving the specified signal of the pressure sensor to check the cover, and consists of a control unit for lighting the LED paired.

이하 본 발명을 첨부된 도면에 의거하여 보다 상세히 설명한다. Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 공동주택에 배선된 전선의 합선방지구조의 구성도이고, 도 2는 본 발명에 따른 공동주택에 배선된 전선의 합선방지구조의 측단면도로서, 도 1 및 도 2에 의하면, 둘레부에 가스가 주입되어 밀폐되는 챔버(21)를 갖는 고무재질의 관형상으로, 외부 전선(W)으로부터 분전된 다수의 전력선(10)을 각각 내설하여 실내 벽체에 배선되는 피복(20)과; 피복(20)의 챔버(21)내에 가스의 압력을 측정하여 기준압력 이하가 되면 고유한 지정신호를 발신하는 압력센서(30)와; 피복(20)과 짝을 이루도록 피복(20)에 상응하는 갯수로 누전차단기(100)에 설치되 는 LED(40); 압력센서(30)의 지정신호를 수신하여 해당 피복(20)을 확인하고, 짝을 이루는 LED(40)를 점등시키는 제어부(50)로 이루어진 구조로 되어 있다.1 is a configuration diagram of a short circuit prevention structure of a wire wired in a multi-unit house according to the present invention, Figure 2 is a side cross-sectional view of the short circuit prevention structure of a wire wired to a multi-unit house according to the present invention, Figures 1 and 2 According to the present invention, a sheath 20 is formed in a tubular shape of a rubber material having a chamber 21 in which gas is injected into a circumference and encloses a plurality of power lines 10 distributed from an external electric wire W to be wired to an indoor wall. )and; A pressure sensor 30 which measures the pressure of the gas in the chamber 21 of the sheath 20 and transmits a unique designation signal when the pressure falls below the reference pressure; LEDs 40 installed in the earth leakage breaker 100 in a number corresponding to the sheath 20 so as to mate with the sheath 20; The control unit 50 is configured to receive the designation signal of the pressure sensor 30, check the cover 20, and turn on the paired LED 40.

상기 피복(20)은, 가요성 고무재질이고, 가스가 주입되는 챔버(21)가 형성되는데, 챔버(21) 내 가스주입방식은 둘레부에 주입구(미도시)를 형성하여 가스를 주입한 뒤 주입구마개(미도시)로 외부와 완전히 차단되도록 형성될수도 있고, 초기 제작시 주입한 뒤 밀봉하여 제작될수도 있다. 또한, 상기 챔버(21)에 주입되는 가스가 대기압과 구분되는 높은 압력을 갖게 되면, 피복(20)이 파손될 경우 가스가 외부로 쉽게 누출되므로, 챔버(21)로 주입되는 가스의 기압은 대기압보다 차이가 클수록 유리할 것이다. 한편, 상기 챔버(21)로 주입되는 가스는 인체에 무해한 것이어야 할 것이다.The sheath 20 is made of a flexible rubber material, and a chamber 21 into which gas is injected is formed. The gas injection method in the chamber 21 forms an injection hole (not shown) at the periphery and injects gas into the chamber. Injection plugs (not shown) may be formed to completely block the outside, or may be manufactured by sealing after injecting during the initial production. In addition, when the gas injected into the chamber 21 has a high pressure that is distinguished from the atmospheric pressure, when the coating 20 is broken, the gas easily leaks to the outside, so the atmospheric pressure of the gas injected into the chamber 21 is greater than the atmospheric pressure. The larger the difference, the better. On the other hand, the gas injected into the chamber 21 should be harmless to the human body.

상기 압력센서(30)는, 기준압력을 갖도록 설정되고, 계속적으로 압력을 측정하여, 자체에 설정된 기준압력보다 챔버(21)에서 측정된 압력값이 낮으면 더 이상의 측정은 하지 않고 고유한 지정신호를 통신라인(L)을 통해 제어부(50)로 발신한다. 또한, 상기 압력센서(30)는 챔버(21) 내에 설치되어야 하므로, 피복(20)의 제작방식에 따라 설치방법이 달라지는데, 일례로 주입구와 주입구마개가 형성된 피복(20)이라면, 주입구와 챔버(21)는 압력센서(30)가 삽입될 수 있는 충분한 크기를 갖는다. The pressure sensor 30 is set to have a reference pressure, and continuously measures the pressure, so that if the pressure value measured in the chamber 21 is lower than the reference pressure set in itself, the pressure sensor 30 does not perform further measurement and a unique designation signal. Send to the control unit 50 through the communication line (L). In addition, since the pressure sensor 30 should be installed in the chamber 21, the installation method varies depending on the manufacturing method of the coating 20. For example, if the coating 20 is formed with the injection hole and the injection plug, the injection hole and the chamber ( 21 is of sufficient size to allow the pressure sensor 30 to be inserted.

상기 LED(40)는, 피복(20)에 설치되는 압력센서(30)와 짝을 이루도록 상응하는 갯수로 누전차단기(100)의 외부에 노출되게 설치되어, 피복(20)의 상태를 나타낸다.The LED 40 is installed so as to be exposed to the outside of the earth leakage breaker 100 in a corresponding number so as to mate with the pressure sensor 30 installed in the sheath 20, indicating the state of the sheath 20.

상기 제어부(50)는, 누전차단기(100)에 내설되고, 압력센서(30)와 통신라인(L)을 통해 전기적으로 연결되어 피복(20)이 파손되면, 챔버(21) 내 가스가 외부로 방출되어, 압력이 일정 기압 이하로 떨어지게 된다. 그러면, 상기 해당 압력센서(30)는 측정된 압력이 설정된 기준압력보다 낮으므로, 더 이상의 측정은 하지 않게 되며, 제어부(50)에서는 지정신호를 확인하여 파손된 피복(20)에 상응하는 LED(40)를 점등시킨다. The control unit 50 is installed in the ground fault circuit breaker 100, and is electrically connected to the pressure sensor 30 through the communication line L so that the coating 20 is broken, the gas in the chamber 21 is moved to the outside. Released, the pressure drops below a certain atmospheric pressure. Then, since the measured pressure is lower than the set reference pressure, the corresponding pressure sensor 30 does not perform any further measurement, and the control unit 50 checks the designated signal to determine the LED corresponding to the damaged coating 20 ( Turn on 40).

본 발명에 따른 공동주택에 배전된 전선의 합선방지구조의 작동상태를 도 1, 도 2 및 도 3을 참조하여 설명해 보면 다음과 같다.Referring to Figures 1, 2 and 3 the operational state of the short-circuit prevention structure of the electric wire distributed to the multi-unit housing according to the present invention.

우선, 본 발명에 따른 전선이 벽체에 설치된 뒤, 상기 피복(20)이 파손되어 설정치 이하로 압력이 떨어지게 되면, 압력센서(30)는 통신라인(L)을 매개로 제어부(50)에 고유신호를 전송한다. 상기 제어부(50)는, 압력센서(30)에서 발신된 고유신호를 입력받아, 도 3과 같이 누전차단기(100)의 외부에 노출되게 설치된 해당 LED(40)를 점등시킨다.First, after the wire according to the present invention is installed on the wall, when the coating 20 is damaged and the pressure drops below the set value, the pressure sensor 30 is a unique signal to the control unit 50 via the communication line (L) Send it. The controller 50 receives the unique signal transmitted from the pressure sensor 30 and turns on the corresponding LED 40 installed to be exposed to the outside of the ground fault circuit breaker 100 as shown in FIG. 3.

한편, 상기 피복(20)이 정상상태일 경우에 LED(40)는 소등상태이다.On the other hand, when the coating 20 is in a normal state, the LED 40 is turned off.

다시 말하면, 상기 각각의 전선에 설치된 여러 압력센서(31,32,33,34)들 중 임의의 피복(20)에 파손이 발생되면, 해당 피복(20)이 내설된 압력센서(30)만 측정을 멈추고 제어부(50)에 지정신호를 발신하게 되고, 제어부(50)에서는 지정신호를 수신받아 이에 해당하는 LED(40)만 점등시켜 외부로 표시한다. 따라서, 누전차단기(100)에 설치된 LED(41,42,43,44)들을 확인하여 해당 전선만 교체하면 된다. In other words, if a breakage occurs in any of the sheaths 20 among the various pressure sensors 31, 32, 33, and 34 installed on the respective wires, only the pressure sensor 30 in which the sheath 20 is installed is measured. Stop and transmits a designated signal to the controller 50, the controller 50 receives the designated signal and lights only the LED 40 corresponding thereto to be displayed externally. Therefore, the LEDs 41, 42, 43, and 44 installed on the ground fault circuit breaker 100 need only to be replaced.

본 발명은 상기한 바와 같은 실시예에 한정되지 않고, 이하의 청구범위를 벗어나지 않는 한도 내에서, 보다 다양하게 변형 실시될 수 있음은 물론이다.The present invention is not limited to the embodiment as described above, and of course, various modifications can be made without departing from the scope of the following claims.

이상 상기한 바와 같이 본 발명에 따르면, 누전차단기(100)에 설치된 LED(40)를 확인하여, 파손된 피복(20)의 손상여부를 손쉽게 확인할 수 있으므로, 해당 전선을 신속히 교체할 수 있어 관리가 용이한 효과가 있다. As described above, according to the present invention, by checking the LED (40) installed in the earth leakage breaker (100), it is easy to check whether the damaged sheath 20 is damaged, it is possible to replace the wire quickly to manage It has an easy effect.
