摘要
分析了观察法、电场法、紫外成像法和红外成像法这 4种合成绝缘子带电检测方法的实验室和现场运行情况 ,总结出它们不同的主要适用范围 :观察法、电场法分别适于外绝缘、导通性内绝缘缺陷 ;紫外成像法、红外成像法分别适于能产生局部放电、局部发热的缺陷。比较而言电场法成本低廉 ,直接检测 ,准确可靠 ,操作简单 。
THE OBSERVATION METHOD, ELECTRIC FIELD METHOD, ULTRAVIOLET IMAGE METHOD AND INFRARED IMAGE METHOD FOR INSULATOR ON LINE DETECTION IS PRESENTED BASED ON THE LABORATORY RESULT AND FIELD OPERATION CONDITION. THE MAIN APPLIED SCOPE OF THESE METHODS ARE ANALYZED. THE ULTRAVIOLET IMAGE METHOD AND INFRARED IMAGE METHOD IS SUITABLE FOR EXTERNAL INSULATION DEFECT AND INTERNAL INSULATION DEFECT RESPECTIVELY. THE OBSERVATION METHOD AND ELECTRIC FIELD METHOD IS SUITABLE FOR PARTIAL DISCHARGE DEFECT AND LOCAL OVERHEAT RESPECTIVELY. COMPARING WITH OTHER METHODS THE ELECTRIC FIELD METHOD HAS THE ADVANTAGES OF LOW COST, DIRECT DETECTION, ACCURATE, RELIABLE AND EASY OPERATION. IT CAN BE WIDELY USED IN CHINA.
