摘要
介绍了超高压线路交流复合绝缘子带电检测方法,如红外测温法、电场法和憎水性分级法等,并结合直流输电线路复合绝缘子的特殊问题,分析了这些方法应用于直流复合绝缘子时的不足和困难,指出在直流复合绝缘子异常发热机理、直流电场测量和憎水性测量等方面均需深入研究。
The on-line detection methods of faulty composite insulators for EHV transmission lines, such as infrared image method, electric field map method and hydrophobicity method, are summarized. Combining with special problems of composite insulators for HVDC transmission lines, the difficulties and defects of applying above-mentioned detection methods to DC composite insulators are analyzed. The authors point out that the aspsects of heating mechanism, the DC electric field distribution and the hydrophobicity detection of high voltage DC composite insulators should be researched in depth.
