Abstract

The present invention relates to an apparatus for preventing an electric shock from an upright pole. More specifically, the present invention relates to an apparatus for preventing an electric shock from an upright pole, in which a pair of planar conductors are installed within the upright pole, thereby substantially reducing a current flowing into the human body with a simple structure even when the upright pole, e.g. a streetlight or a traffic light, is flooded. Further, a flow path from an input-side wire to an output-side wire is electrically connected on an electric circuit in parallel with a path from the human body to the ground by providing a planar conductor between the input-side wire and the output-side wire of the upright pole so as to induce a larger amount of current to flow into the planar conductors, which have relatively much less electric resistance compared to the current flowing into the human body, so that almost no current is supplied to the human body even when the upright pole is flooded, thereby preventing an electric shock. In addition, safety can be maximized by additionally inserting a ground structure between the pair of planar conductors.

Figurine 10 is installed on the floor including the ground can be used in a variety of fields, such as lighting, traffic signals, displays, voice broadcasting, for example, a concept including a street lamp and traffic lights.
제1 평판형 도전체(42)는 입력측 제1 전선(22)과 출력측 제1 전선(32) 사이에 각각 전기적으로 연결된다. 즉, 제1 평판형 도전체(42)의 일단은 입력측 제1 전선(22)에 전기적으로 연결되고, 타단은 출력측 제1 전선(32)에 전기적으로 연결된다. The first flat conductor 42 is electrically connected between the input first wire 22 and the output first wire 32, respectively. That is, one end of the first flat plate-shaped conductor 42 is electrically connected to the input side first wire 22, and the other end is electrically connected to the output side first wire 32.
입력측 제1 전선(22)은 지중 또는 지상으로부터 입상주(10) 내부로 인출되어 입상주(10) 상부의 램프 등 부하에 전원을 공급한다. 도 1 및 도 2에는 입력측 제1 전선(22)이 지중으로부터 입상주(10) 내부로 인출되는 예가 도시되어 있으나, 지면이나 지상을 통해서도 전원이 공급될 수 있음은 물론이다.The input first first wire 22 is drawn out from the ground or the ground into the granular column 10 to supply power to a load such as a lamp on the granular column 10. 1 and 2 illustrate an example in which the input-side first electric wire 22 is drawn from the ground into the granular column 10, but power may be supplied through the ground or the ground.
출력측 제1 전선(32)은 램프, 스피커, 디스플레이 패널과 같은 부하에 전기적으로 연결되어 부하에 전원을 공급하며, 통상 입상주(10) 내부에 위치한다.The output first wire 32 is electrically connected to a load such as a lamp, a speaker, and a display panel to supply power to the load, and is usually located inside the standing column 10.
제1 평판형 도전체(42)의 폭은 입력측 제1 전선(22)과 출력측 제1 전선(32) 중 적어도 어느 하나의 두께보다 넓고 길이는 입력측 제1 전선(22)과 출력측 제1 전선(32) 중 적어도 어느 하나의 두께보다 길게 형성된다. 또한, 제1 평판형 도전체(42)의 폭과 길이를 곱한 면적은 입력측 제1 전선(22)과 출력측 제1 전선(32) 중 적어도 어느 하나의 단면적의 4배 이상인 것이 바람직하다. The width of the first flat plate-shaped conductor 42 is wider than the thickness of at least one of the input side first wire 22 and the output side first wire 32, and the length thereof is the input side first wire 22 and the output side first wire ( It is formed longer than the thickness of at least one of 32). In addition, it is preferable that the area multiplied by the width and the length of the first flat plate-shaped conductor 42 is four times or more than the cross-sectional area of at least one of the input-side first wire 22 and the output-side first wire 32.
또한, 제2 평판형 도전체(44)는 입력측 제2 전선(24)과 출력측 제2 전선(34) 사이에 각각 전기적으로 연결된다. In addition, the second flat plate type conductor 44 is electrically connected between the input second wire 24 and the output second wire 34, respectively.
입력측 제2 전선(24)은 지중 또는 지상으로부터 입상주(10) 내부로 인출되어 입상주(10) 상부의 램프 등 부하에 전원을 공급한다. 마찬가지로 입력측 제2 전선(24)은 지중뿐만 아니라, 지면이나 지상을 통해서도 전원을 공급할 수 있음은 물론이다.The input second second wire 24 is drawn out from the ground or the ground into the granular column 10, and supplies power to a load such as a lamp on the granular column 10. Similarly, the input second wire 24 can supply power not only in the ground but also through the ground or the ground.
출력측 제2 전선(34)은 램프, 스피커, 디스플레이 패널과 같은 부하에 전기적으로 연결되어 부하에 전원을 공급하며, 통상 입상주(10) 내부에 위치한다.The second wire 34 on the output side is electrically connected to a load such as a lamp, a speaker, and a display panel to supply power to the load, and is usually located inside the standing column 10.
제2 평판형 도전체(44)의 폭은 입력측 제2 전선(24)과 출력측 제2 전선(34) 중 적어도 어느 하나의 두께보다 넓고 길이는 입력측 제2 전선(24)과 출력측 제2 전선(34) 중 적어도 어느 하나의 두께보다 길게 형성된다. 또한, 제2 평판형 도전체(44)의 폭과 길이를 곱한 면적은 입력측 제2 전선(24)과 출력측 제2 전선(34) 중 적어도 어느 하나의 단면적의 4배 이상인 것이 바람직하다. The width of the second flat plate type conductor 44 is wider than the thickness of at least one of the input side second wire 24 and the output side second wire 34, and the length thereof is the input side second wire 24 and the output side second wire ( It is formed longer than the thickness of at least one of 34). In addition, it is preferable that the area multiplied by the width and the length of the second flat plate-shaped conductor 44 is at least four times the cross-sectional area of at least one of the input second wire 24 and the output second wire 34.
통상 입력측 제1 전선(22)과 출력측 제1 전선(32), 입력측 제2 전선(24)과 출력측 제2 전선(34)은 물리적으로, 또 전기적으로 동일한 규격으로 형성되나, 본 발명이 이에 한정되는 것은 아니다. 감전방지장치는 송배전 경로에 설치되므로 통상 입력측 제1 전선과 출력측 제1 전선은 물리적으로, 전기적으로 동일한 전선이며, 입력측 제2 전선과 출력측 제2 전선은 물리적으로, 전기적으로 동일한 전선이다. 그러나 본 발명이 이에 한정되는 것은 아니다.Usually, the input first wire 22 and the output first wire 32, the input second wire 24 and the output second wire 34 are physically and electrically formed to the same standard, but the present invention is limited thereto. It doesn't happen. Since the electric shock prevention device is installed in the transmission / distribution path, the input first wire and the output first wire are physically and electrically the same wire, and the input second wire and the output second wire are physically and electrically the same wire. However, the present invention is not limited thereto.
통상 제1 평판형 도전체(42)와 제2 평판형 도전체(44)는 서로 동일한 규격과 동일한 재질로 형성되나, 본 발명이 이에 한정되는 것은 아니다.Usually, the first flat plate type conductor 42 and the second flat plate type conductor 44 are formed of the same standard and the same material, but the present invention is not limited thereto.
제1 평판형 도전체(42)와 제2 평판형 도전체(44)는 전기적으로 이격되며, 물리적으로 서로 이격되어 대향하도록 배치될 수 있다. 본 발명을 전기회로 이론에 의해 완전히 설명할 수는 없지만 전기적으로 볼 때 본 발명에 따른 침수보호장치는 물에 잠겼을 때 두 평판형 도전체 사이에 물이 차고, 결국 두 평판형 도전체와 그 사이에 존재하는 물에 의해 형성되는 전기적 저항체가 된다. 전기저항은 저항체의 길이에 비례하고 단면적에 반비례하므로 평판형 도전체가 대향할 때 단면적이 최대가 되고 길이가 최소로 되어 전기저항이 최소가 된다. 이에 따라 인체와 접지면에 대해 병렬로 연결될 때 더 저항이 큰 인체로 흐르는 전류를 최소화할 수 있다.The first planar conductor 42 and the second planar conductor 44 may be electrically spaced apart and physically spaced apart from each other. Although the present invention cannot be fully explained by the theory of electric circuits, the immersion protection device according to the present invention, when viewed in water, is filled with water between two planar conductors when submerged, and eventually between two planar conductors and between them. It becomes an electrical resistor formed by the water present in the. Since the electrical resistance is proportional to the length of the resistor and inversely proportional to the cross-sectional area, the cross-sectional area is maximized when the plate-shaped conductors face each other and the length is minimized to minimize the electrical resistance. Accordingly, when connected in parallel to the human body and the ground plane, it is possible to minimize the current flowing to the human body with more resistance.
한편, 본 발명에 따른 입상주 감전방지장치는 제1 평판형 도전체와 제2 평판형 도전체가 대향하는 채로 세워진 상태로 설치되며, 침수로부터 보호하고자 하는 대상 전기기기보다 낮은 위치에 설치된다. 예컨대 가로등의 경우 하부에 노출된 제어기는 방수된 공간에 설치되지만 이 공간에 빗물 등이 차게 되면 주변 사람들은 감전위험에 놓이게 된다. 감전방지장치는 이 방수공간에 설치되면서 제어기보다 낮은 위치로 설치되어 제어기가 침수되는 시점보다 먼저 침수되고 이로 인해 먼저 작동할 수 있게 된다.On the other hand, the standing column electric shock prevention device according to the present invention is installed in a state in which the first plate-type conductor and the second plate-type conductor are opposed to each other, and is installed at a lower position than the target electric equipment to be protected from flooding. For example, in the case of a street lamp, the controller exposed at the bottom is installed in a waterproof space, but when rainwater is filled in the space, the people around it are at risk of electric shock. The electric shock prevention device is installed in this watertight space and is installed at a lower position than the controller so that the controller is submerged before the controller is submerged and can operate first.
제1 평판형 도전체와 제2 평판형 도전체는 입상주의 내부에 물리적으로 고정된다. 도 1 및 도 2의 실시예는 2선식에 적용되므로 2개의 평판형 도전체가 고정되지만, 3선식의 경우 3개의 평판형 도전체들을 고정하는 형태가 된다. 도시되지 않았으나 이러한 평판형 도전체는 별도의 하우징에 고정될 수 있으며, 하우징은 부도체인 플라스틱 또는 세라믹 재질로 제조될 수 있다.The first planar conductor and the second planar conductor are physically fixed inside the granular column. 1 and 2 is applied to a two-wire type, so two flat conductors are fixed, but in the case of a three wire type, three flat conductors are fixed. Although not shown, the plate-shaped conductor may be fixed to a separate housing, and the housing may be made of a plastic or ceramic material which is a non-conductor.
제1 평판형 도전체와 제2 평판형 도전체의 재질은 구리(Cu)인 것이 바람직하다. 실험에 따르면 평판형 도전체의 재질이 철, 알루미늄 등일때 보다 구리인 경우가 배터리로부터 인쇄회로기판 등으로 흐르는 전류를 최소화할 수 있는 효과가 우수하였다.It is preferable that the material of a 1st flat type conductor and a 2nd flat type conductor is copper (Cu). According to the experiment, when the flat conductor is made of iron or aluminum, copper has a better effect of minimizing the current flowing from the battery to the printed circuit board.
본 발명에 대한 실험은 선출원발명과 유사한 구조로 설계될 수 있다.Experiments on the present invention can be designed in a structure similar to the previous invention.
선출원발명에서는 수조에 물을 채우고 일단이 플러그에 연결된 감전방지장치를 수조에 담그고, 타단의 램프를 수조 바깥에 노출시킨 후, 플러그를 전원 콘센트에 연결하여 전원을 공급한다. 시험자는 전선의 노출된 일단을 잡고 타단을 수조에 담근 상태에서 전선을 통해 흐르는 전류를 전류계로 측정한다.In the present invention, the tank is filled with water, one end of the electric shock prevention device connected to the plug is immersed in the tank, the other end of the lamp is exposed outside the tank, and the plug is connected to a power outlet to supply power. The investigator grasps the exposed end of the wire and dips the other end into the water bath, measuring the current flowing through the wire with an ammeter.
선출원발명의 실험결과 모든 평판형 도체의 사이즈에 대해 인체를 통과하는 전류는 미약하여 문제가 없음을 보여준다. 선출원발명의 실험은 단상 교류가 수조의 물을 통해 흐르면 입체 저항체인 물 안에서 전압강하가 일어나고, 인체가 접촉시 물과 접지면 사이에 인체를 통해 흐르는 전류는 물에 담그는 위치에 따라 단상 교류의 중간값 전후로 결정되므로 일반적인 단상 교류에 직접 접촉한 경우보다 실제로는 훨씬 낮은 교류 전원에 노출되는 셈이 되어 초래되는 결과로 추정된다. Experimental results of the present invention show that the current through the human body is small for all flat conductor sizes, so there is no problem. In the experiment of the present invention, when the single-phase alternating current flows through the water of the tank, the voltage drop occurs in the water, which is a three-dimensional resistor, and when the human body contacts, the current flowing through the human body between the water and the ground plane is in the middle of the single-phase alternating current depending on the position of the water. Since it is determined before and after the value, it is estimated that the result is actually exposed to much lower AC power than when directly contacting the general single-phase AC.
본 발명에서는 수조에 물을 채우고 입상주의 하부가 물에 잠기도록 한 후, 시험자는 전선의 노출된 일단을 잡고 타단을 수조에 담근 상태에서 전선을 통해 흐르는 전류를 전류계로 측정하면 된다.In the present invention, after the tank is filled with water and the lower part of the columnar column is immersed in water, the tester may grasp the exposed end of the wire and immerse the other end in the tank, and measure the current flowing through the wire with an ammeter.
두 평판형 도전체 사이의 물이라는 전기적 저항체의 중간부분이 접지된 상태로 전기회로적으로 모델링할 수 있다. 인체는 이러한 전기적 저항체와 접지면 사이에 연결되는 또 다른 저항체로 모델링할 수 있다. 인체라는 저항체와, 두 평판형 도전체와 접지면 사이에 연결된 물이라는 저항체들이 전기회로적으로 병렬로 연결되어 인체로 흐르는 전류를 제한하는 것은 기존의 전기회로적인 해석으로 이해가 될 수 있다.An electrical circuit can be modeled with the ground of the middle of an electrical resistor, called water, between the two planar conductors. The human body can be modeled as another resistor connected between this electrical resistor and the ground plane. The resistance of the human body and the resistance of the water connected between the two plate conductors and the ground plane are connected in parallel in an electrical circuit to limit the current flowing to the human body.
인체를 통해 흐르는 전류는 평판형 도전체의 면적과 원통형 전선(제1 전선과 제2 전선)의 단면적의 비와 관련이 있다. 여기서 평판형 도전체의 면적이란 평판형 도전체의 펑판 모양에서 폭과 길이를 곱한 값을 말한다. 원통형 전선의 단면적을 πr2이라 하면 폭은 2r이므로, 평판형 도전체의 면적은 r2, 2r2, 4r2, 8r2, 16r2 등에 해당하고 전선 단면적과 평판형 도전체의 면적의 비는 π/1, π/2, π/4, π/8, π/16 등에 해당한다. 실험 결과 평판형 도전체의 면적이 대략 원통형 전선의 단면적의 4배 이상일 경우 일반적인 상태에서 인체에 위험하지 않는 정도의 전류가 흐름을 확인하였다.The current flowing through the human body is related to the ratio of the area of the planar conductor and the cross-sectional area of the cylindrical wire (first wire and second wire). Here, the area of the flat conductor refers to a value obtained by multiplying the width and the length in the flat plate shape of the flat conductor. If the cross-sectional area of the cylindrical wire is πr 2 , the width is 2r. Therefore, the area of the flat conductor corresponds to r 2 , 2r 2 , 4r 2 , 8r 2 , 16r 2, and the ratio of the wire cross-section to the area of the flat conductor is Corresponds to π / 1, π / 2, π / 4, π / 8, π / 16 and so on. As a result of the experiment, when the area of the plate-shaped conductor is approximately four times larger than the cross-sectional area of the cylindrical wire, the current flows to a degree that is not dangerous to the human body.

도 2의 실시예는 한 쌍의 평판형 도전체 사이가 접지된다는 점 이외에는 도 1의 실시예와 유사하므로, 차이점을 중심으로 설명한다.Since the embodiment of FIG. 2 is similar to the embodiment of FIG. 1 except that the pair of planar conductors is grounded, the description will be mainly focused on differences.

Is inserted. At this time, the ground wire 52 is electrically connected to one end of the grounding conductor 50 (the lower end of FIG. 2), and the ground wire 52 is grounded to the ground.
도 1의 실시예와 같이 한 쌍의 평판형 도전체만 구비되어도 감전을 충분히 방지할 수 있음을 실험적으로 확인하였으나, 도 2와 같이 접지용 도전체가 추가적으로 설치되어 접지할 경우 안전성을 극대화할 수 있게 된다.Experimentally confirmed that the electric shock can be sufficiently prevented even if only a pair of flat plate-like conductors as shown in the embodiment of Figure 1, but as shown in Figure 2 additionally the grounding conductor is additionally installed to maximize safety do.
