본 고안은 단로기(disconnector switch)로서 좀 더 상세하게는 교류전력 계통에서 벼락 써지 또는 회로 개폐에 의한 과전압을 제한하며 속류를 차단하는 피뢰기 하부측에 부착되어 배전 선로상의 이상동작 전압으로부터 피뢰기를 분리 할 수 있고 피뢰기의 이상유무를 식별할 수 있는 단로기에 관한 것이다.The present invention is a disconnector switch, and more specifically, it is attached to the lower side of the arrester that blocks the overcurrent and restricts the overvoltage caused by lightning surge or circuit opening and closing in AC power system to separate the arrester from abnormal operation voltage on the distribution line. The present invention relates to a disconnector capable of identifying an abnormality of an arrester.
교류전력계통에서 벼락써지 또는 개폐써지등의 이상전압으로부터 각각 기기를 보호하기 위하여 일종의 보호장치인 피뢰기를 설치하여 피뢰기 외형의 하우징 또는 쉐드는 외부환경으로부터 한류소자 등의 내부 부품을 보호하고 써지와 과전압에 의한 한류소자가 발열할 때 수축 팽창에 의한 균열 및 이완이 없는 구조를 유지하도록 하며 전기적으로 충분한 연면 누설거리와 설정거리를 이루고 강우나 습기, 염진, 오염 등에 노출되어도 항상 임계치 이상의 절연을 유지하여야 한다.In order to protect the equipment from abnormal voltage such as lightning surge or switching surge in AC power system, a lightning arrester, a kind of protection device, is installed.The housing or shed of the lightning arrester protects the internal parts such as the current-limiting element from the external environment. Maintains a structure free from cracking and relaxation due to contraction and expansion when the current-limiting element is generated by heating, and achieves sufficient creepage leakage distance and setting distance electrically and always maintains insulation above the threshold even when exposed to rainfall, moisture, dust, pollution do.
그러나 이러한 피뢰기의 보호장치에도 불구하고 교류전력 계통에서 완전하게 과전압을 방지하고 속류를 차단할 수 있도록 상기 피뢰기의 하부에 단로기를 설치하여 배전선로상의 동작 전압으로부터 피뢰기를 분리하고 피뢰기의 이상유무를 식별할 수 있도록 하고 있는바, 본 고안은 이러한 단로기의 기능을 좀 더 확실하게 하고 또 향상시킬 수 있도록 그 구조를 개선한 것으로 이하 첨부도면에 의하여 상세히 설명하면 다음과 같다.However, in spite of the protection device of this arrester, the disconnector is installed in the lower part of the arrester so that the AC power system can completely prevent overvoltage and cut off the current. The present invention is to improve the structure of the disconnector to be more sure and improve the function of the disconnector as described in detail below by the accompanying drawings as follows.
피뢰기의 하부에 부착될 수 있는 상부캡(1)과 하부캡(2) 및 내부에 이상전압 입력시 상부 캡(1)과 하부캡(2)을 분리할 수 있는 장치를 갖춘 페놀수지재의 보디(3)로 구성되어 있으며 상부캡(1)에는 볼트형성시에 비하여 피뢰기와의 체결을 용이하고 견고하게 할 수 있도록 너트부(1A)를 형성하였다.Body of phenol resin material having upper cap (1) and lower cap (2) that can be attached to the lower part of the arrester and a device that can separate the upper cap (1) and the lower cap (2) when an abnormal voltage is input into the inside ( It is composed of 3) and the upper cap (1) was formed with a nut portion (1A) to facilitate fastening and fastening to the arrester compared to the bolt formation.
보디(3)에는 이상 전압시 분리가 되는 분리부(3A)를 1개 또는 2개 이상을 형성하고 보디(3)의 내부에는 상기 상부캡(1)의 너트부(1A)로 입력되는 수십KV의 전압이 걸리는 저항(10)이 상부캡(1)과 연결되며 임계저항이상이 되면 작동하도록 된 작약(5)(화약)을 내장한 작약튜브(6)가 리벳(9)에 대하여 일정 간극을 두고 설치된다. 상기 리벳(9)과 작약튜브(6)의 간극은 1.2mm 에서 3.0mm 로 되어있다.The body 3 is provided with one or two or more separation parts 3A separated at the time of abnormal voltage, and several tens of KV input to the nut part 1A of the upper cap 1 inside the body 3. The resistance tube 10, which is connected to the upper cap 1, is connected to the upper cap 1, and when the resistance exceeds the threshold resistance, the peony tube 6 having a built-in peony 5 (powder) has a predetermined gap with respect to the rivet 9. Put and installed. The gap between the rivet 9 and the peony tube 6 is from 1.2 mm to 3.0 mm.
상기 저항(10)과 작약튜브(6) 및 리벳(9)은 내부케이스(4)로 둘러싸여 스프링(7)에 의해 동판(8)을 사이에 두고 하부캡(2)과 연결되어 있다.The resistor 10, the peony tube 6, and the rivet 9 are surrounded by an inner case 4 and connected to the lower cap 2 with the copper plate 8 interposed therebetween by a spring 7.
상기 하부캡(2)의 일측의 나사조임부(2A)는 2중 너트를 형성함으로서 접지전선을 체결함에 있어 포설환경 또는 풍우로 인한 장기간 사용시 볼트의 풀림을 방지하도록 하였다.Screw tightening portion (2A) of one side of the lower cap (2) is to form a double nut to fasten the grounding wire to prevent loosening of the bolt in the long-term use due to the installation environment or weather.
이상과 같이 형성된 본 고안의 단로기의 상부캡(1)의 너트(1A)와 피뢰기의 하부를 나사 고정하였고 하부캡(2)의 나사조임부(2A)에는 2 중너트를 형성하여 리벳(9)을 스프링(7)의 탄력으로 견고하게 고정한다. 피뢰기를 통해 수십KV의 전압이 입력되어 저항을 통해 하부캡으로 전류가 흐리게 되나 임계저항을 넘는 저항이 입력되면 작약튜브(6)내에 있는 작약(5)(화약)이 작동하므로 폭발이 되어 내부케이스(4)에 이어 페놀수지인 보디(3)의 분리부(3A)가 파단되므로 단로가 된다. 이때 보디(3)의 분리부(3A)를 2개이상 형성하면 피뢰기로부터 이상 써지 입력시, 보다 손쉽게 분리가되어 단로 효과가 더욱 상승될 수 있다.The nut 1A of the upper cap 1 and the lower part of the lightning arrester of the disconnector according to the present invention formed as described above are screwed, and a double nut is formed on the screw tightening part 2A of the lower cap 2 to rivet 9. It is firmly fixed to the elasticity of the spring (7). When the voltage of several tens of KV is input through the arrester and the current is blurred to the lower cap through the resistance, when the resistance exceeding the threshold resistance is applied, the charge (5) (powder) in the charge tube (6) is activated, which causes an explosion Subsequent to (4), the separating portion 3A of the body 3, which is a phenol resin, is broken, so that it is disconnected. In this case, when two or more separation parts 3A of the body 3 are formed, when an abnormal surge is input from the arrester, the separation effect can be more easily increased, and the disconnection effect can be further increased.
이상과 같은 단로기의 전체적인 형상 구조는 중심선을 대칭으로 동등한 무게중심을 유지하여 피뢰기 연결부의 국부적 피로 강도를 감소할 수 있는 효과도 있다.The overall shape structure of the disconnector as described above has the effect of reducing the local fatigue strength of the arrester connecting portion by maintaining the center of gravity equal to the center line symmetrically.
