摘要:
针对劣化复合绝缘子容易使输电线路发生闪络、跳闸、芯棒脆断等事故,严重威胁电力系统安全运行的问题,对护套和芯棒间存在碳化通道这种劣化情况下的复合绝缘子进行研究。采用有限元法对复合绝缘子碳化芯棒周围电场进行计算分析,建立绝缘子仿真计算模型,并在实验室条件下,现场测量护套和芯棒间存在碳化通道的沿串电场分布,实验测量数据与仿真结果基本一致,验证了理论计算的正确性。研究结果表明,碳化通道会畸变绝缘子串空间电场的分布,通道距高压端越近畸变越明显; 碳化通道所贯穿的绝缘子伞裙其内部的电场值有所增大。
Abstract:
The degraded composite insulator easily causes flashover,tripping and brittle fracture of the transmission line,which seriously threaten the safety of power system. The insulators with the carbonization channel between the sheath and the mandrel were studied. The electric field around the carbonized mandrel bar was calculated and analyzed by finite element method. The simulation model of the insulator was established. The electric field distribution along the carbonization channel between sheath and mandrel
was measured in laboratory. The experimental data were in good agreement with the simulation results,and the correctness of theoretical calculation was verified. The results show that the carbide channel make the space electric field value distortion,the closer is channel from high voltage side,the more obvious is distortion; the electric field value inside the insulator shed of the carbonization channel is increased
