摘　　要：针对佛山电网500kV罗北甲线、500kV罗西甲线绝缘地线并联间隙故障,分析了故障发生的原因及放电对线路造成的影响,进一步从理论上阐述了绝缘架空地线并联间隙的选取,提出了改进的措施。According to the accident caused by the shunt gaps trouble Of the insulating ground wire discharges on 500kV luo- bei I line and 500kV Luo-xi I line of Foshan power grid, in this paper, the caused reason and influence on the line by discharge is analyzed. Finally, the selecting of insulating ground wire shunt gaps is expatiated theoretically, and given the improvement on it.
