SF6环网开关柜合闸不同期测试结果的不确定度评定

摘要

不确定度表明测量结果的可信赖程度,在报告物理量测量结果时,给出相应的不确定度,一方面便于评定其可靠性,另一方面也增强了测量结果间的可比性.首先简单介绍了SF6环网开关柜合闸同期性的重要性与不同期合闸所产生的危害,给出了一个用开关机械特性测试仪测量合闸不同期的例子,并且对测量结果进行了不确定度评定.%Uncertainty indicates the trustworthiness of measurement result. Gives the corresponding uncertainty in reporting the result of physical measurement, on one hand to facilitates the assessment of its reliability, on the other hand to enhances the comparability of measurement result. Firstly, this paper briefly introduces the importance of switching synchronization of SF6 ring main unit and the hazards arising from switching non-synchronization. Then gives a switching Non-synchronization testing example using switch mechanical properties tester,and evaluates the uncertainty of measurement result.
