摘要
低压电器分断试验中通断时间和燃弧时间对产品优化设计有着重要意义,但现有的人工选择燃弧点的方式存在较大的误差。提出了采用小波变化的新算法,进行了小波变换奇异性检测方面的试验分析。通过具体试验波形的分析,验证了采用小波变换算法进行波形分析的可行性。
The make-break time and arc time of low voltage apparatus break time test are important to the products optimization design, but the artificial selection of arc point is imprecise. The new algorithm based on wave transform was proposed, and the singularity detection was analyzed. The real test form indicats the feasibility of wave form analysis based on wavelet transform.
