본 발명은 송전변전 배전 피뢰기의 마운팅 브라켓 높이조절 장치에 관한 것으로서, 보다 구체적으로는 피뢰기에 장애물이 접촉되는 것을 방지하기 위해 피뢰기 설치 위치의 조절을 가능하는 송전변전 배전 피뢰기의 마운팅 브라켓 높이조절 장치에 관한 것이다.The present invention relates to a mounting bracket height adjustment device of a power transmission substation distribution arrester, and more particularly, to a mounting bracket height adjustment device of a transmission substation distribution arrester capable of adjusting an installation arrester position to prevent an obstacle from contacting an arrester. It is about.

일반적으로 발전소, 변전소, 송배전선로, 전차선로, 전기기기 등은 번개에 의한 고전압의 침입이나 선로의 특정 부분에서 이루어지는 차단기, 스위치의 개폐 등에 의해 일어나는 이상 고전압이 침입될 우려가 있다. 피뢰기는 선로나 전기기기를 이런 고전압으로부터 보호하기 위해 설치된다. 따라서 피뢰기는 정상전압으로는 전류가 흐르지 않으나 번개 등이 침입하였을 경우에는 도전성의 전로가 되어 고전압을 저하시키는 기능이 있어야 한다. 더구나 고전압의 침입이 끝났을 때는 다시 전류가 흐르지 않는 성질로 돌아가는 기능도 아울러 갖추어야 한다.In general, power plants, substations, transmission and distribution lines, tram lines, electrical equipment, etc., may invade abnormal high voltages caused by invasion of high voltages by lightning, breakers, switch openings, and the like at specific portions of the line. Lightning arresters are installed to protect the line or electrical equipment from these high voltages. Therefore, the arrester must have a function of lowering the high voltage as it is a conductive path in case of lightning invasion, although no current flows through the normal voltage. In addition, when the high voltage invasion is finished, it should also have the function of returning to the property that no current flows again.
