摘要
主要研究±500kV直流输电线路劣化绝缘子的带电检测方法。分析了应用分布电压测量法、声波测量法、红外测温法、电场检测法和憎水性分级法检测复合绝缘子时的效果,并指出在直流复合绝缘子异常发热测量、直流电场测量和憎水性测量等方面仍需深入研究。
This paper mainly researches the method of line detection of ±500kV DC transmission line fault insulators. Analysis of the application of distributed voltage measurement, acoustic measurement, infrared temperature measurement, field test and the hydrophobic classification method for the detection of composite nsulators in effect, and points out that in the DC composite insula tor abnormal heating measurement, the measurement of DC electric field and hydrophobic measurement, still needs further study.
