摘　　要：高压开关设备的可靠性在电力系统中所起的作用至关重要,笔者主要从影响开关设备工作可靠性的电磁干扰方面开展研究,依据可靠性的评价原则,提出反映可靠性的主要特征参量,结合相关标准及设备应用的现实状况,逐一开展电磁干扰试验,并对试验结果进行记录、分析,根据得到的试验数据,运用层次分析法的原理,在构造判断矩阵的基础上,通过计算,得出了不同干扰项目针对不同高压开关设备类别在可靠性影响方面所占的权重。结果表明,浪涌冲击具有破坏性,电快速瞬变脉冲群和阻尼振荡易引起设备工作故障,但不易造成设备损坏。这种分析方法对高压开关设备的可靠性评价具有参考价值。According to the reliability evaluation principle of high-voltage switchgears, the main characteristic parameters which concern the reliability were proposed. Combining the characteristic parameters with the corresponding national standards and switchgear applications, electromagnetic interference test for each parameter was conducted, and the test data were analyzed. The judgement matrix is constructed with the test data on the basis of the analytic hierarchy process to obtain the weight of each parameter which influences the reliability of different type of high-voltage switehgear. The results indicate that surge impact is of destructivity, EFT pulse series and damper oscillatary wave can cause switchgear fault but not failure. This study may be helpful reliability evaluation of high-voltage switchgears.
