초록

본 논문에서는 고정된 전선과 원형 실린더에 부착되는 icing 으로 인해 발생되는 하중(icing의 무게 및 풍하중)에 관한 실험을 수행하고 그 결과를 수록하였다. 실험은 이동 가능한 풍동을 이용하여 냉동실 실험과 실혼 실험으로 구분하여 실시하였다. 냉동실 실험에서는 icing으로 인한 하중의 시간적 변화를 측정하였으며, 실온 실험에서는 특제작한 icing 모형을 이용하여 풍속 변화에 따른 풍하중 변동을 측정하였다.

Presented herein are the results of a laboratory study on structural loads (icing weight and wind loads) associated with icing formation on rigidly fixed, circular power-transmission cables and cylinders. The experiments were carried out using movable wind tunnel under two different conditions: refrigerated and non-refrigerated conditions. Temporal evolution of icing loads were determined in the refrigerated laboratory and wind loads for icings at several stages of icing formation were measured in the non-refrigerated laboratory.
