| 摘 要： | 为分析绝缘子污层表面干燥带的产生对其电场分布的影响,在ANSYS中建立了染污110 kV瓷支柱绝缘子的模型,分析了其在干燥带出现前后电场和电位的变化情况,分析了干燥带容易出现的区域以及干燥带位置、宽度、数量、电阻率对沿面场强的影响.结果表明:柱体较之伞裙更易岗发热而出现干燥带;出现干燥带后其附近电位发生突变,干燥带附近...

| Abstract: | A model of 110 kV porcelain post insulator with pollution layer was established in ANSYS,and the electric field and potential distribution of insulator in the presence or absence of dry band were obtained.Then,the region where dry band easily generated was analyzed.Finally,the influences of dry band position,width,number and resistivity on surface electric field were analyzed.The results show that the dry band is generated more easily in the cylinder than in the shed.The potential close to dry band will cha... |
