摘要
本文较全面介绍了国内外绝缘子在线检测的方法,从非电量的到电量的;从接触的到非接触的;从离线的到在线的。主要介绍了直接观察法、紫外成像法、红外成像法、超声波检测法、等值盐密法、陡波试验法、电势测量法、电阻法、电场法、泄漏电流法和脉冲电流法在绝缘子检测方面的应用。叙述了每种方法的基本原理、实现方法和相应的不良绝缘子的检定方法以及每种方法的优点和缺点,并给出实际应用中的实用性分析。
This paper study on the on-line monitoring method of insulator within the cotmtry and abroad, which is from electrical method to non-electrical, from tangent method to untangent, from on-line to off-line. This manuscript mainly describes the application of Direct Observed Method, Ultraviolet Radiation Imaging Method, Infrared Imaging Method, Ultrasonic Detecting Method, ESDD, Steep Front Impulse Test, Potential Detection, Resistance Measurement, Electric Field Measurement, Leakage Current Measurement, Inpulse Current Measurement on the on-line monitoring of insulator. This paper enucleates the frndamental, achieved method, and the merit and shortcoming of each method, and it also come out the analyzing of practicability.
