输电线路劣化绝缘子电场分布仿真与检测研究
|
摘要
为有效检测出高压输电线路劣化绝缘子,降低劳动强度,文中首先分析了绝缘子串周围的电场分布规律,并利用Ansys软件仿真验证了利用电场分布原理实现绝缘子劣化检测的可行性,简要阐述了基于电场分布原理设计的劣化绝缘子自动检测装置。考虑到检测装置本身可能会对绝缘子串的周围电场分布造成影响,利用Ansys软件对比分析了有无检测装置时的绝缘子电场分布,仿真结果表明,检测装置的存在不影响劣化绝缘子的判别。最后,在实验室及现场对劣化绝缘子检测装置进行了零值绝缘子及存在导通性缺陷的绝缘子检测试验,结果表明,文中基于电场法的绝缘子劣化检测装置能够准确识别出劣化绝缘子。
In order to effectively detect the faulty insulator on high-voltage transmission line,and reduce the laborintensity,this paper firstly analyzes the electric field distribution around the insulator string,and verifies the feasibili-ty of the faulty insulator detection based on the electric field distribution principle using Ansys software. Then the de-tecting principle of the automatic detection device for the deteriorated insulator is briefly described in this paper. Con-sidering the detection device may affect the electric field distribution,the electric field distribution along insulator stringwith detection device or not is simulated in Ansys software. The simulation results show that the existence of the de-tection device has no influence on the judgment of the deteriorated insulator. Finally,the insulator detection tests ofthe insulator string with zero-value insulator or conductive defects are carried out in the laboratory and in the field.The results show that the device based on the electric field method can accurately identify the deteriorated insulator.
