摘要
等温松弛电流(IRC)法由于可有效评估多种电气设备的老化状态,因此在高压电气设备绝缘老化状态评估中被广泛应用。首先,介绍了IRC的基本测试原理及其在不同电气设备绝缘老化评估中的应用;然后,根据各电气设备绝缘老化类型,整理并总结了利用IRC对设备绝缘老化进行评估的适用范围;最后,对电力设备绝缘老化评估方面亟需解决的问题及未来的研究方向进行了展望。
The Isothermal Relaxation Current(IRC)method is widely used in the assessment of the ageing state of insulation in high voltage electrical equipment,as it can effectively assess the ageing state of a wide range of electrical equipment.The paper begins with an introduction to the basic test principles of IRC and its application in the assessment of insulation ageing of different electrical equipment,followed by a compilation and summary of the scope of application of IRC for the assessment of the insulation ageing of electrical equipment according to the type of insulation ageing.Finally,the problems to be solved and the future research directions in the assessment of insulation ageing of power equipment are prospected,in order to provide reference for the establishment of a standardised system for the assessment of insulation ageing of power equipment.
