摘要
为指导电力工程测试及科研试验选择正确的试验方法,合理确定电气间隙绝缘试验关键指标,进一步提高绝缘参数获取的准确性,结合试验及参数统计方法分析优化了长空气间隙多级法试验中的多个技术指标,并推荐了超/特高压等级长空气间隙多级法试验中较优的级数、单级试验次数、总体试验次数等指标,以及每组试验最长持续时间等重要控制条件,研究对于指导日常电气绝缘试验具有实用价值。
In order to provide correct test methods for electric power engineering and scientific research,determine reasonably the key indicators of insulation test for electric clearance,and further improve the accuracy of insulation parameters obtaining,this paper analyzes and optimizes several technical indicators of the test for long air gaps with multi-stage method based on the test and parameter statistical methods,and recommends considering several indicators,including the stage number,single-stage test times,total test times of the test for EHV and UHV long air gaps with multi-stage method and other important control conditions such as the longest duration of each group of tests.The research has practical significance for the daily electrical insulation test.
