摘　　要：提出了用韦伯概率分布模型处理多次放电数据的方法,按照绝缘子串耐受且防弧金具间隙击穿的概率达到99.85%的标准来设计间隙距离,该方法准确、易操作。通过试验,得到了昆明高海拔地区(海拔2 000 m)10 kV架空绝缘导线P15针式绝缘子加装防弧金具的间隙距离。The method of processing several discharge voltages＇ data using Weibull probability plot model is presented, According to the standand that probability of insulator string tolerance and arc - protection hardware gap breakdown achieve 99. 85% to design the gap distance. The method has the eharaeteristics of accuracy and easy to operate. By test results, the best gap distance of arc - protection hardware used for 10 kV overhead insulation lines and P15 pin insulators is 9. 5 cm. The result provides methods and ex- periment basis for the application of arc - protection hardware at high altitude areas.
