一、前言为了防止电气设备的绝缘击穿事故,从很早就开始了非破坏试验判定绝缘老化的研究。但是,由于使用环境和运转条件的多样性,老化机理的复杂性、试验条件的不统一及试验方法的繁杂等原因,准确地诊断出所有情况下的老化状态是非常困难的。最近,实行以判定绝缘老化为中心的维修管理,无疑可以防止绝缘事故发生。同时,还在积极地进行判定残余寿命的试验。现在迫切要求确立判定绝缘老化的统一的诊
I. Preface In order to prevent the insulation breakdown of electrical equipment, non-destructive testing has been initiated from a very early age to determine the study of insulation aging. However, it is very difficult to accurately diagnose the aging state in all cases due to the diversity of the use environment and operating conditions, the complexity of the aging mechanism, the inconsistency of the test conditions, and the complicated test methods. Recently, the maintenance management centering on the determination of insulation aging can undoubtedly prevent the occurrence of insulation accidents. In the meantime, tests for determining the remaining life are still actively carried out. There is an urgent need to establish a unified clinic to determine the aging of insulation
