STUDY ON INTEGRATED MONITOR AND CONTROL OF THE APPARATUS QUALITY BASED ON THE MULTI-PARAMETER ANALYSIS

摘要

Electric arc is an especial switching apparatus's phenomenon in switching loop current, reliability and using life of apparatus can be directly influenced by time of arcing, which is considered as the important index of switching apparatus. According to the time of apparatus arcing, we can divide it into different grades. Factors that influence the time of apparatus arcing include material, design, techniques, operation, power, equipment and circumstance. Selecting all these factors as sample, using the time of apparatus arcing to determine the sample type, we can extract the key factor using FICSEM in the same type samples, and can obtain the factor combination that achieve the same apparatus arcing time. We can improve the product quality by improving the key factor, and can reduce the product cost by using the optimal factor combination. So we can evade producing risks and can improve economy benefits.
