Description

가공 배전선로의 전자파 차단장치{ELECTROMAGNETIC WAVE CUTOFF APPARATUS OF DISTRIBUTION LINE}Electromagnetic wave blocking device of overhead distribution line {ELECTROMAGNETIC WAVE CUTOFF APPARATUS OF DISTRIBUTION LINE}

본 발명은 가공 배전선로의 전자파 차단장치에 관한 것으로써, 더욱 상세하게는 배전선로가 수용되는 배전선로틀의 상부에 차폐틀을 설치하고, 배전선로틀의 하부에 차폐판을 설치하여 전자파의 유출을 차단하는 한편, 배전선로틀의 상부에 대한 개폐가 원활하게 이루어질 수 있도록 하여 배전선로틀로의 배전선로의 인입,인출이 용이하게 이루어질 수 있도록 하기 위한 가공 배전선로의 전자파 차단장치에 관한 것이다.The present invention relates to an electromagnetic wave shielding device for an overhead distribution line, and more particularly, by installing a shielding frame on an upper portion of a distribution line frame in which a distribution line is accommodated, and installing a shielding plate on the lower portion of the distribution line frame to prevent electromagnetic wave outflow On the other hand, it relates to an electromagnetic wave blocking device of an overhead distribution line for smoothly opening and closing the upper part of the distribution line frame, thereby making it easy to enter and withdraw the distribution line to the distribution line frame.

일반적으로 전자파의 일종인 X선이나 감마선은 강한 에너지를 갖고 있어 많이 쏘였을 경우 태아 기형 등 세포에 악영향을 끼친다.In general, X-rays or gamma rays, which are types of electromagnetic waves, have strong energy, so if they are irradiated a lot, they adversely affect cells such as fetal malformations.

예를 들면, 레이더 기지나 전자레인지 등에 사용되는 마이크로파의 세기를 강하게 하면 음식물이 익을 정도다.For example, if you increase the intensity of microwaves used in radar bases or microwave ovens, the food is cooked enough.

그래서 전자파의 인체 유해성 시비는 전자파의 세기가 약한 휴대폰, TV, 컴퓨터, 고압송전선 등에 장기간 노출됐을 때 인체가 어떤 영향을 받는가에 초점이 맞춰져 있는데, 전자파 유해성 논란에 불을 지핀 고압 송전선의 경우는 50∼60Hz에 불과한 극저주파이다. 참고로, 전자레인지용은 25억Hz이다.Therefore, the debate about the harmfulness of electromagnetic waves to the human body is focused on how the human body is affected when exposed to mobile phones, TVs, computers, and high-voltage power lines with weak electromagnetic waves for a long period of time. It is an extremely low frequency of only ∼60 Hz. For reference, it is 2.5 billion Hz for microwave ovens.

아파트 단지 등에는 전력선과 통신선 등의 많은 케이블이 설치되는데, 이러한 케이블은 공중으로 배선할 경우 자체의 하중으로 인해 아래로 처질 뿐 아니라 다른 구조물과 간섭되어 손상될 우려가 높다.Many cables, such as power lines and communication lines, are installed in apartment complexes, and when these cables are wired in the air, there is a high risk of being damaged by interference with other structures as well as drooping down due to their own load.

이에 따라, 케이블을 수용하는 트레이를 슬래브 아래로 설치된 행거에 안착시켜 케이블을 지지하는 구조가 이용된다.Accordingly, a structure for supporting the cable by seating the tray for accommodating the cable on a hanger installed below the slab is used.

그러나, 트레이는 상부가 개방되어 있어서, 고전압을 수송하는 케이블로부터 발생하는 전자파가 슬래브를 통하여 거주지역까지 미치게 되어 인체 및 전자기기에 악영향을 끼칠 수 있는 문제점이 있다.However, since the upper part of the tray is open, electromagnetic waves generated from the cable carrying high voltage reach the residential area through the slab, and there is a problem that may adversely affect the human body and electronic equipment.
