摘　　要：分析了传统局部放电模型由气隙几何位置、放电起始电压与放电熄灭电压间差值及放电能量消耗方式等导致的不确定因素,指出仅根据视在放电量的大小评价绝缘状况是不准确的,在对电力设备绝缘进行诊断时应对各种因素和条件综合考虑。The factors of indefiniteness in the conventional model of partial discharge are analyzed especially, and it is indicated that it is not accurate to evaluate the status of insulation according to the value of apparent charge only. All factors and conditions must be considered completely during the process of diagnosis of the insulation of power equipments.
