Test Research and Analysis of CW1-2000 Intelligent Air Circuit Breaker

On the basis of the analysis of CW1 2000 intelligent air circuit breaker, the assessment specifications of the reliability of the products were presented. According to test results, the reliability analysis on the data of accumulative test time, accumulative failure number of times and average non failure time in the operative mechanism, under voltage release and electromagnet to switch on were carried out. The test results indicate that the failure are caused mainly by vibration and fatigue. The improvement measures are given, and the practical test proved that it is more effective for the products.
