摘要
据统计,输电线路各类事故中雷击跳闸事故占有很大比例。通过对哈密地区一起110 kV雷击跳闸事故的计算、分析,得出反击是造成输电线路跳闸的主要原因,并就此提出几点提高线路耐雷水平、降低雷击跳闸率的措施。
According to statistics, transmission lines in all types of accidents account for a large proportion of lightning Accident. Lightning trip through the calculation of a 110 kV accident Hami region, analyze, draw back is the main cause of transmission line trip and to make a few points to improve the level of mine-resistant line, measures to reduce the rate of lightning trip.
