산불화재에 의한 전력선 섬락사고 기초연구(II)
Basic Study on Flashover Characteristics of Power Lines by Forest Fire(II)
초록
Occurring forest fire or burning bushes beneath overhead transmission lines have caused system disturbances in many countries. In this study, various tests in the simulated condition of power lines were conducted so as to investigate the reduction in insulation strength caused by combustion flame. The results of an experimental investigation into the flashover characteristics of air dielectric strength in the presence of oil flame are reported. It is demonstrated that flame can reduce by more than half, 80% in maximum, the breakdown voltage of a model line.
