| 摘 要： | 触头的电寿命是断路器研究比较关心的～项内容，传统的断路器电寿命评估方法是统计开断电流的大小与次数，从而估算出电磨损。这种方法用在触头电寿命的在线监测却不够准确。以小波理论作为工具，提出了在线监测燃弧时间的方法，改进了触头电寿命评估的理论，并为断路器电寿命的在线监测提供了一条新思路。

| Abstract: | The electrical life of circuit breakers are much concerned in studies, and the traditional assessment method uses the statistical dropout current size and number of times to estimate the electrical wear. This method is of statistical significance, but is not accurate enough. Based on wavelet theory as a tool, this paper puts forward the online monitoring arc time method, which can improve the contact electric life evaluation theory, and provide a new way of thinking for the online monitoring of the electrical life for circuit breakers. |
