Description

이동통신 기지국 낙뢰방지용 피뢰기Lightning arrester for mobile communication base station

본 발명은 이동통신 기지국의 송신기 및 수신기를 보호하기 위하여 장착되는 일종의 장비 보호장치인 피뢰기에 관한 것으로, 특히 정재파나 삽입손실을 개선하면서 반 영구적으로 사용이 가능한 이동통신 기지국 낙뢰방지용 피뢰기에 관한 것이다.The present invention relates to a lightning arrester which is a kind of equipment protection device mounted to protect a transmitter and a receiver of a mobile communication base station. In particular, the present invention relates to a mobile communication base station lightning arrester which can be used semi-permanently while improving standing waves or insertion loss.

현재 이동통신 기지국에 사용되는 피뢰기는 몸체, 인덕턴스(L), 커패시턴스(C), 가스방전관등의 소자들로 구성되어 있다. 여기서, 피뢰기 내부의 가스방전관은 피뢰기의 몸체와 접속되어 있으며, 상기 피뢰기의 몸체는 접지와 연결되어 있다.Currently, the arrester used in the mobile communication base station is composed of elements such as body, inductance (L), capacitance (C), gas discharge tube. Here, the gas discharge tube inside the arrester is connected to the body of the arrester, the body of the arrester is connected to the ground.

상기와 같은 피뢰기를 이용하여 고가의 통신장비를 보호하는 작용상태를 간략히 설명하면, 낙뢰가 발생할 경우, 대부분의 낙뢰는 철탑이나 건물에 의해 땅속으로 소멸되고, 나머지는 안테나와 연결되어 있는 통신 케이블을 통해 이동통신 기지국 내부의 장비로 유입된다. 이때, 상기 피뢰기 내부로 유입된 낙뢰는 가스방전관의 방전에 의해 접지로 흘러가서 고가의 이동통신 기지국의 장비를 보호하는 것이다.Briefly explaining the operation of protecting expensive communication equipment using the lightning arrester as described above, when a lightning strike occurs, most of the lightning strikes are destroyed in the ground by steel towers or buildings, and the rest is connected to the communication cable connected to the antenna. Through the flow into the equipment inside the mobile communication base station. At this time, the lightning strike introduced into the arrester flows to the ground by the discharge of the gas discharge tube to protect the equipment of the expensive mobile communication base station.

그러나 종래의 피뢰기는 여러차례 방전이 이루어짐에 따라 가스방전관내의 가스가 소진되며, 결국 방전이 되지 않을 경우 기지국 통신 장비가 손상될 우려가 있기 때문에 적절한 시기에 교체하여야만 한다. 이에따라 일정한 주기마다 잦은 교체를 해야하기 때문에 번거로움이 있으며. 또한 상기 피뢰기 안의 각 소자들의 연결부위나 간격등에 의해 특성의 변화가 심하기 때문에 통상적인 삽입손실값인 0.2데시벨(dB)을 초과하게 되거나, 정재파가 1.2 : 1이상으로 되는 문제점이 있다.However, the conventional lightning arrester has to be replaced at an appropriate time since the gas in the gas discharge tube is exhausted as the discharge is made several times, and thus the base station communication equipment may be damaged when the discharge is not performed. This is cumbersome because it requires frequent replacements at regular intervals. In addition, since the characteristic change is severe due to the connection portion or the interval of each element in the arrester, there is a problem that exceeds the normal insertion loss value of 0.2 decibel (dB) or the standing wave is 1.2: 1 or more.

따라서, 본 발명은 상기한 제반 문제점을 해결하기 위해 안출된 것으로서, 피뢰기내의 각 소자를 제거하고 1/4파장 단락바만을 채용하여 정재파나 삽입손실을 개선하고 반 영구적으로 사용이 가능한 이동통신 기지국 낙뢰방지용 피뢰기를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, removes each element in the arrester and employs only 1/4 wavelength short bar to improve the standing wave or insertion loss, semi-permanently used mobile communication base station lightning Its purpose is to provide an arrester for prevention.

Inner bar (1) is inserted and fixed to receive the power from the transmitter to the antenna to be applied to the receiver, is mounted in the vertical direction in the center of the inner bar (1) to ground the lightning introduced from the communication line 1/4 wavelength short bar (2) is mounted. In addition, a short circuit body 4 is fitted to the outer circumferential surface of the quarter-wave short bar 2 so as to match the impedance with the quarter-wave short bar 2 while protecting the short bar 2.

상기 단락몸체(4)의 외주면에는 단락커버(5)가 체결되며, 상기 단락커버(5)의 중앙홀로 단락바(2)가 삽압되도록 하여 그의 편심을 유지하도록 지지하며, 상기 단락커버(5)와 단락몸체(4) 및 상기 단락몸체(4)와 하우징(3)의 체결부에는 O링(9)이 삽입되어 습기가 단락바(2)에 스며드는 것을 방지한다.The short circuit cover 5 is fastened to the outer circumferential surface of the short circuit body 4, and the short circuit bar 2 is inserted into the center hole of the short circuit cover 5 so as to maintain the eccentricity thereof, and to support the short circuit cover 5. And the O-ring 9 is inserted into the short circuit body 4 and the fastening portion of the short circuit body 4 and the housing 3 to prevent moisture from penetrating into the short circuit bar 2.

한편, 상기 단락몸체(4)의 상부에는 상기 1/4파장 단락바(2)가 끼워진채로 너트(6), 스프링와셔(7) 및 평와셔(8)가 순차적으로 장착되어 접지와 연결이 용이하도록 구비된다.On the other hand, the nut (6), the spring washer (7) and the flat washer (8) are sequentially mounted on the upper portion of the short circuit body (4) while the quarter-wave short bar (2) is fitted to facilitate connection with the ground. It is provided to.

상기와 같이 구성된 본 발명의 작용상태를 설명하면 다음과 같다.Referring to the working state of the present invention configured as described above are as follows.

상기 입력커넥터(10)를 통하여 송신기로부터의 전력을 인가받아 출력커넥터(11)를 통하여 안테나로부터 유입된 전력을 수신기에 전달한다. 그리고, 낙뢰가 발생할 경우에는 1/4파장 단락바(2)를 통하여 접지에 연결한다. 이때, 안테나 입력단에서 피뢰기의 내부를 들여다보면 장비쪽의 임피던스는 50Ω이고, 접지와 연결되어 있는 1/4파장 단락바(2)쪽의 임피던스는 0Ω이므로, 낙뢰는 임피던스가 높은 쪽에서 낮은 쪽으로 흐르기 때문에 장비쪽으로의 유입은 전혀 일어나지 않게 된다. 이때, 상기 너트(6), 스프링와셔(7), 평와셔(8)의 결합에 의해 견고하게 고정되므로써 접지와의 연결이 풀리지 않게되며. 또한 상기 단락몸체(4)와 단락바(2)가 일정간격으로 유지되도록 임피던스 정합을 하게 되는 것이다.The power received from the transmitter is input through the input connector 10, and the power introduced from the antenna is transmitted to the receiver through the output connector 11. And, in case of lightning, it is connected to ground through 1/4 wavelength short bar (2). At this time, if you look inside the arrester at the antenna input, the impedance of the equipment is 50Ω and the impedance of the 1/4 wavelength short bar (2) connected to the ground is 0Ω, so the lightning flows from the higher impedance to the lower. No entry into the equipment takes place at all. At this time, by being firmly fixed by the combination of the nut (6), spring washer (7), flat washer (8), the connection to the ground is not released. In addition, impedance matching is performed such that the short circuit body 4 and the short bar 2 are maintained at a predetermined interval.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

전술한 바와 같이 본 발명에 따르면, 1/4파장 단락바에 의해 낙뢰가 발생했을 때 임피던스가 높은쪽에서 낮은쪽으로 흐르도록 하여 장비쪽으로의 유입을 신뢰성있게 방지하므로써 종래와 같은 소자들이 없이도 피뢰기능을 신뢰성있게 수행할 뿐만 아니라, 반 영구적으로 사용할 수 있는 효과를 가진다.As described above, according to the present invention, when a lightning strike occurs due to a quarter-wave short bar, the lightning protection function flows from the high impedance side to the low side to reliably prevent the inflow into the equipment, thereby reliably preventing the lightning protection function without the conventional devices. In addition to performing, it has the effect of being used semi-permanently.
