摘　　要：简述了复合绝缘子各种在线检测技术包括直接观测法、紫外成像法、红外成像法、超声波法、电场测量法、憎水性检测、泄漏电流测量等的测量原理、适用范围、优缺点。特别介绍了一种基于便携式复合绝缘子憎水性在线检测装置的硬、软件组成部分、检测判断标准和操作程序。现场试验证明了该方法的可行性。Currently, some methods have been applied, which mainly include visual method, ultraviolet image method, infrared image method, ultrasonic pulse-echo method, electric field method, hydrophobicity measurement, leakage current measurement, and so on. In this paper, the detecting principles, applicability, advantages and shortcomings of these methods are analyzed. Then, an on-line hydrophobicity detection method based on portable device is brought forward. The device includes hard and software. The on-site tests conducted on some 110 kV and 220 kV transmission lines in central China show that the method is suitable for on-line hydrophobicity detection.
