摘要
Abstract
A high-power DC relay is taken as the research object.The contact movement after contact separation is measured by physical prototypes.By changing the contact breaking speed,the arc duration and the duration of each stage of DC arc under different breaking speeds are recorded.The results show that after the contact separation of the high-power DC relay,the contact breaking speed decreases to zero when the contact reaches the maximum opening distance after complex regular changes.The maximum contact breaking speed directly indicates the breaking capacity of the contact for high-power DC loads.The improvement of the maximum contact breaking speed can significantly shorten the liquid metal bridge and metal-phase arc periods,effectively increase the breaking times of the high-power DC relay for high-power DC loads and improve the insulation performance after breaking,which is of positive significance for the breaking of high-power DC loads.关键词
