본 발명은 폭우시 빗물에 침수된 전기 맨홀의 전기 접속부로부터 전기감전을 근본적으로 방지하는 장치에 관한 것으로, 더욱 상세하게는 감전방지수단을 설치함으로써 침수시 누전으로 인해 흐르는 전기의 전압과 전류를 모두 흡수하여 감전 방지 장치가 설치된 외부에는 전기가 완전히 차단됨으로써 안전사고를 근본적으로 방 지하여 인명피해를 줄일 수 있도록 한 감전방지장치에 관한 것이다. The present invention relates to a device for fundamentally preventing an electric shock from the electrical connection of the electric manhole immersed in rainwater during heavy rains, and more specifically, by installing an electric shock prevention means, both the voltage and the current of the electricity flowing due to a short circuit during flooding The present invention relates to an electric shock prevention device which is capable of reducing personal injury by fundamentally preventing safety accidents by completely blocking the outside of the electric shock absorbing device installed therein.

이를 위하여 본 출원인은 2004년 10월 4일 날짜로 특허 출원번호 10-2004-0084163로 출원하였고 대한민국 실용신안등록이 제20-0339079-00008호(이하, 인용발명이라 칭함)를 인용하여 발명하였습니다. To this end, the applicant filed a patent application No. 10-2004-0084163 dated October 4, 2004, and invented the Korean Utility Model Registration by citing No. 20-0339079-00008 (hereinafter referred to as cited invention).

일반적으로 고압 또는 저압전기 맨홀이 침수되면 전기 접속부에서 전기가 누전 될 수가 있다. In general, when high voltage or low voltage manholes are flooded, electrical leakage may occur at the electrical connections.

그리고, 그 누전된 전기는 물속에서도 전압이 높은쪽에서 낮은쪽으로 또는 대지로 사방으로 흘러가려는 성질을 가지고 있다.In addition, the shorted electricity has a property of flowing in all directions from high to low voltage or to earth even in water.

일반적으로 고압 또는 저압전기 맨홀이 침수되면 감전사고는 맨홀의 높은 전압 그리고 전류와 대지 사이의 물에 의해서 감전사고가 일어난다. In general, when a high or low voltage manhole is flooded, an electric shock is caused by the high voltage of the manhole and water between the current and the ground.

이때, 물에 누전되어 흐르고 있는 고압 또는 저압전기와 전류를 감전방지장치에서 모두 흡수하면 맨홀 밖으로는 감전사고를 근본적으로 방지할수있다. At this time, if the high-voltage or low-voltage electric current flowing in the water and all the current absorbed by the electric shock prevention device can prevent the electric shock accident outside the manhole.

그러나, 종래에는 맨홀에 전기 접속부에서 누전되는 전기로 인하여 안전사고 등이 발생하는 경우가 잦았다. 그 경우 인명피해 등의 대형사고로 직결될 수 있는 등의 문제점이 있었다. However, in the related art, safety accidents are frequently caused due to the electrical leakage from the electrical connection to the manhole. In this case, there were problems such as being directly connected to a large accident such as human injury.

이와 같이 감전 사고를 방지하기 위하여 본 출원인은 특허 출원번호 제10-2004-0084163호로 출원하였고 여기에서 침수 감전 방지 장치를 전주, 전동기, 고압변압기, 교통신호제어기 등에 적용하였다. 그러나, 맨홀의 내부는 물에 침수되어 있는 상태이므로 전주, 전동기, 고압변압기, 교통신호제어기 등과는 다른 방식으로 누전사고를 방지해야할 필요성이 있다. In order to prevent an electric shock as described above, the applicant has applied for a patent application No. 10-2004-0084163, and applied the immersion electric shock prevention device to electric poles, electric motors, high voltage transformers, traffic signal controllers, and the like. However, since the inside of the manhole is inundated with water, it is necessary to prevent a short circuit accident in a different manner from electric poles, electric motors, high voltage transformers, and traffic signal controllers.

또한, 맨홀은 매운 비좁은 공간이며 열악한 환경이어서 자칫 작은 실수로 인하여 감전사고 등이 발생하면 구조가 매우 어려운 문제점 등이 있다. In addition, the manhole is a very cramped space and a poor environment, so if the electric shock accident occurs due to a small mistake, the structure is very difficult.

본 발명은 상기와 같은 종래의 문제점을 해결하고, 전술한 필요성을 충족시키기 위하여 안출된 것으로, 고압 또는 저압 맨홀에 전선 접속부와 전기법규에서 규정하는 상(전기)과 접지간의 절연거리를 확보한 상태에서 접지된 도전성이 높은 금속판 또는 금속 망으로 이루어진 침수감전방지기를 해당 맨홀에 맞게 설치하여 물속에서 흐르는 전류가 침수감전방지기에 의해 흡수되어 전기가 근본적으로 맨홀 외부로 유출 될 수가 없도록 감전 사고를 미연에 방지할 수 있는 침수감전방지장치를 제공함을 목적으로 한다.The present invention has been made in order to solve the above-mentioned conventional problems and to meet the above-mentioned necessity, and to secure an insulation distance between a wire connection portion and a phase (electricity) and ground defined by an electric code in a high or low voltage manhole. In order to prevent the electric shock from flowing out of the manhole, the electric current is absorbed by the immersion electric shock prevention device by installing the immersion electric shock prevention device consisting of a highly conductive metal plate or a metal net grounded at the manhole. It is an object of the present invention to provide an apparatus to prevent flooding electric shock.

상기 목적을 달성하기 위한 본 발명은 침수 되는 모든 고압 또는 저압 맨홀에 전선 접속부와 전기법규에서 규정하는 상(전기)과 접지간의 절연거리를 확보한 상태에서 접지된 도전성이 높은 금속판 또는 금속 망으로 이루어진 침수감전방지기를 해당 맨홀에 맞게 설치하여 물속에서 흐르는 전류가 침수감전방지기에 의해 흡수되어 전기가 근본적으로 맨홀 외부로 유출 될 수가 없도록 감전 사고를 미연에 방지할 수 있는 침수감전방지장치를 제공함을 목적으로 한다.The present invention for achieving the above object is made of a highly conductive metal plate or a metal mesh grounded in a state that ensures the insulation distance between the wire connection and the phase (electrical) and ground prescribed in the Electric Code to all high-pressure or low-pressure manholes submerged The purpose of the present invention is to provide a submersion electric shock prevention device that prevents electric shock accidents so that the electric current flowing in the water is absorbed by the submersion electric shock prevention device so that electricity can not flow out of the manhole. It is done.

이하, 본 발명의 구성에 대하여 첨부된 도면을 참조하여 보다 상세하게 설명 한다. Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 일실시예에 따른 맨홀의 내부에 적용된 침수감전방지기를 위에서 본 정면도이며, 도 2는 본 발명의 일실시예에 따른 맨홀의 내부에 적용된 침수감전방지기를 측면에서 바라본 측면도이다. 1 is a front view of the immersion electric shock protector applied to the inside of the manhole according to an embodiment of the present invention, Figure 2 is a side view of the immersion electric shock protector applied to the inside of the manhole according to an embodiment of the present invention from the side. .

도 1 및 도 2를 참조하여 본 발명의 원리에 대하여 살펴보면 다음과 같다. 맨홀(1) 내측에는 상측으로 금속판 또는 금속 망으로 이루어진 상측전기흡수판(4)이 맨홀(1)의 내측 일측에 맨홀(1)의 뚜껑으로부터 이격되어 고정되어 있다. The principle of the present invention will be described with reference to FIGS. 1 and 2 as follows. On the inside of the manhole 1, an upper side electroabsorbing plate 4 made of a metal plate or a metal mesh is fixed to the inner side of the manhole 1 and spaced apart from the lid of the manhole 1.

상측전기흡수판(4)은 연결선(6)을 통해 전선 입.출구 전기흡수판(5)과 연결되어 있다. 상측전기흡수판(4)은 나충전부(전기기기 또는 전기 장치 또는 본 발명의 침수감전방지장치 중 절연이 이루어지지 않아 통전시 감전 또는 누전을 일으킬 수 있는 모든 부분을 의미함)를 대표하는 전선접속부(3)를 통해 전기가 유출되거나, 기타 전기가 흐르는 전선(2)의 피복이 벗겨져 전기가 유출되면, 이를 흡수하는 역할을 한다. The upper side electrical absorption plate 4 is connected to the wire inlet and outlet electrical absorption plate 5 through the connecting line (6). The upper side electrical absorption plate 4 is a wire connecting part representing the charging unit (meaning any part of the electrical equipment or electric device or the immersion electric shock prevention device of the present invention that can cause electric shock or short circuit when the electricity is not supplied) If electricity is leaked out through (3) or the cover of other wires through which electricity flows is peeled off and electricity is leaked, it serves to absorb the electricity.

상측전기흡수판(4)에서 흡수된 전기는 전선 입.출구 전기흡수판(5)과 상호 상호 커패시터(capacitor)의 역할을 하여 이와같이 나충전부 또는 전선접속부(3)를 통해 흘러나온 전기를 접지선(9)을 통해 우선적으로 충전하여 바로 접지(E) 또는 중성선(N)부(7)로 흘려 보내게 된다. The electricity absorbed by the upper electrical absorption plate 4 acts as a mutual capacitor as the wire inlet / outlet electrical absorption plate 5 and thus, the electricity flowing through the uncharged part or the wire connecting part 3 is connected to the ground wire ( 9) it is preferentially charged through the ground (E) or the neutral (N) portion 7 is sent to flow.

상측전기흡수판(4)과 전선 입.출구 전기흡수판(5)에서 흘러나온 전기를 충전하면, 상측전기흡수판(4)과 전선 입.출구 전기흡수판(5)에서 충전된 전기는 접지선(9)을 통해 접지단(E)으로 흐르거나, 또는 중성선(N)을 통해 빠져나가게 된다. When the electricity flowing out of the upper electrical absorption plate (4) and the wire inlet / outlet electrical absorption plate (5) is charged, the electricity charged in the upper electrical absorption plate (4) and the wire inlet / outlet electrical absorption plate (5) is grounded. Through (9) it flows to the ground terminal (E), or exit through the neutral (N).

한편, 상측전기흡수판(4)을 맨홀(1) 형태에 맞추어 구성한다. 이때, 상측전기흡수판(4)이 맨홀(1)의 몸체와도 닿지 않도록 다수의 절연체인 브라켓 등으로 맨홀(1)의 일측과 상측전기흡수판(4) 또는 전선 입.출구 전기흡수판(5)이 상호 닿아 있지 않도록 하여야 하며, 고정시키는 수단은 절연체 등을 이용하여 고정시킨다.On the other hand, the upper side of the electrical absorption plate 4 is configured in accordance with the shape of the manhole (1). At this time, one side of the manhole (1) and the upper side of the absorption plate (4) or the wire inlet and outlet electrical absorption plate (4) with a bracket, such as a plurality of insulators so that the upper side of the absorption plate (4) does not touch the body of the manhole (1) 5) should not be in contact with each other and the fixing means should be fixed by using an insulator.

한편, 전선 입.출구 전기흡수판(5)은 접지선(9)에 의해 접지(E) 또는 중성선(N)부(7)에 연결되고, 전력이 인가되어 전선(2)에 전류가 흐르고 맨홀(1)의 내측에 물이 고여있는 경우에는 맨홀 전체가 나충전부가 될 수 있다. 이때, 전류는 물보다 전도도가 높은 상측전기흡수판(4)과 전선 입.출구 전기흡수판(5)에 충전된다. On the other hand, the wire inlet and outlet electrical absorbing plate (5) is connected to the ground (E) or the neutral (N) portion (7) by the ground wire (9), the power is applied to the current flows through the wire (2) and the manhole ( If water is accumulated inside 1), the entire manhole may be a bare part. At this time, the electric current is charged in the upper electrical absorption plate 4 and the wire inlet and outlet electrical absorption plate 5 having higher conductivity than water.

그리고, 맨홀(1) 전체가 나충전부로서의 역할을 하는 상태에서 상측전기흡수판(4)과 전선 입.출구 전기흡수판(5)은 유출되어 사람의 안전을 위협할 수도 있는 전류를 저장하는 커패시터의 역할을 하며, 충전되는 즉시 접지(E) 또는 중성선(N)부(7)를 통해 빠져나가는 것이다. Then, in the state where the entire manhole 1 serves as a low-charge part, the upper electric absorbing plate 4 and the wire inlet / outlet electric absorbing plate 5 flow out to store a current that may threaten human safety. It acts as, and is discharged through the ground (E) or neutral (N) portion 7 as soon as it is charged.

따라서, 침수된 물에 사람의 몸이 접촉되더라도 접촉된 물을 통해 인체에 흐르는 전류는 감지할 수 없을 만큼 작아, 감전 사고 또는 누전 사고가 방지된다. 즉, 맨홀의 내부에 접속된 전선들과 전기법규에 규정하는 상(전기)과 접지 간의 절연거리를 확보한 상태에서 접지(E) 또는 Therefore, even if a person's body is in contact with the flooded water, the electric current flowing through the human body through the contacted water is undetectable so that an electric shock or an electric leakage accident is prevented. That is, the ground (E) or the ground with the insulation distance between the wires connected inside the manhole and the phase (electricity) and ground prescribed in the Electric Code

된 상측전기흡수판(4)과 전선 입.출구 전기흡수판(5)에 충전된 전류가 접지(E) 또는 중성선(N)부(7)를 통해 빠져나가 전기는 대지로 흐르게 되어 중화되는 것이다. The current charged in the upper side electrical absorption plate 4 and the wire inlet / outlet electrical absorption plate 5 exits through the ground (E) or the neutral line (N) portion 7 and the electricity flows to the ground and is neutralized. .

한편, 미설명 부호 8은 전선 입.출 개구부(8)로 전선이 맨홀(1)의 내측으로 인입하고 인출되는 각각의 개구부를 통칭한다. On the other hand, reference numeral 8 denotes respective openings through which wires are introduced into and drawn out of the manhole 1 to the wire entry and exit openings 8.
