摘要
分析了电力电缆终端及中间接头过热缺陷的产生原因 ,给出了防范措施 ,同时依据诊断实例 ,参照国家颁布的《带电设备红外诊断技术应用导则》和GB76 3 90《交流高压电器在长期工作时的发热》所规定的上限值 ,提出了适合现场红外工作人员操作的电缆头过热缺陷诊断细则 。
The reason of overheat defectiveness of electric cable termination and joints is analyzed in detail, the preventive measure is given at the same time according to a large quantity of diagnostic example and prescriptive upper limit of “Application standard of infrared diagnose technique on charged arrangement” and GB762 90 “ Heating of Ac HV Electric Equipment in long term”, detailed diagnostic rules and regulations of overheat defectiveness of cable head is proposed.. It offers the basis for diagnosis of overheat defectiveness of cable head.
