Abstract
This paper describes the characteristics of a newly suggested arc-inducing driven rod with needles which could effectively spread out both the failure current with power frequency and the lightning current. The structural characteristic of the driven rod was that needles were attached on the surface of the conventional shaped driven rod and the driven rod with needles was installed inside of a copper pipe.As a result of analyzing the characteristics of this suggested driven rod when it was employed as the driven rod of an arrester in distribution system, it was verified that the primary voltage of the arrester was reduced by effectively exhausting the electrical energy since the arc occurred between the needle and the copper pipe.
본 논문에서는 상용주파 고장전류 및 뇌격전류를 모두 효과적으로 대지로 방류할 수 있는 새로운 형태의 접지 봉인 아크유도형 침부 접지봉을 고안하여 특성올 연구, 분석하였다. 아크유도형 침부 접지봉의 구조는 일반 접지 용의 표면에 침을 부착한 후 동파이프에 넣었다. 이 고안된 접지봉이 배전선로의 피뢰기 접지봉에 사용될 경우의 특성올 검토한 결과, 침과 동파이프 사이에서 아크가 발생하여 전기에너지를 효과적으로 소모함으로써 피뢰기 1차측 전압이 감소됨을 확인하였다.
