摘要
针对隔离开关电器在不同频率(50 Hz和60 Hz)相同电流下,温升存在一定的差异的情况,研究了隔离开关温升与工作频率的关系。通过相关温升试验结果的比对分析,得出了不同频率下温升的补偿系数。验证试验结果表明,补偿系数具有可参考性,可为相关人员进行隔离开关的温升检测提供参考。
AS the temperature rise on switch-disconnectors will be different when the different frequency current is loaded , the relations among work frequency and temperature rise were analyzed. The temperature rise test under different frequency were carried out. The reference data were got by analyzing the results. After that , the test carried out on another specification of disconnector verified the validity of the reference data. The results can provide reference for the relevant personnel to detect the temperature rise of switch-disconnectors.
