Claims (4)
- 전기적 절연거리, 지표면 전계강도의 유지 및 상당(相當)전선의 조수증가를 감안하여 철탑의 높이와 전선의 기상고가 높게 가설되는 초고압 송전선로 전선의 원주표면에서 고공풍에 의한 와류현상으로 발생되는 풍소음을 방지하도록 가공송전선(10)의 최외층과 동일한 피치로 전선의 직경에 따라 소정의 직경을 갖는 알미늄재질의 단선을 나선형으로 꼬아 밀착 취부한 나선형 첨선(20)을 부가 설치함을 특징으로 하는 나선형 첨선을 이용한 송전선 풍소음 저감장치.
- 제 1 항에 있어서,상기 나선형 첨선(20)은 두 개의 단선(21)(22)을 각각 띄워 나선형으로 꼬아 밀착 취부하는 대각 2조방식으로 취부함을 특징으로 하는 나선형 첨선을 이용한 송전선 풍소음 저감장치.
- 제 1 항에 있어서,상기 나선형 첨선(20)은 두 개의 단선(21)(22)을 밀착시켜 나선형으로 꼬아 취부하는 밀착 2조방식으로 취부함을 특징으로 하는 나선형 첨선을 이용한 송전선 풍소음 저감장치.
- 제 1 항에 있어서,상기 나선형 첨선(20)은 두 개의 단선(21)(22)을 나선형으로 꼬아 밀착하여 1조를 이루고, 상기 밀착 구성된 1조의 단선이 쌍을 이루도록 하여 각각 띄워 나선형으로 꼬아 밀착 취부하는 대각밀착 4조 방식으로 구성됨을 특징으로 하는 나선형 첨선을 이용한 송전선 풍소음 저감장치.
