This is the total time from energizing the trip coil until the interruption of current on the primary arcing contacts. 此时间为从跳闸线圈受电到主触头电弧电流开断为止的总时间。
On the basis above, influences of the parameter changes in nozzle, maximum openning distance, main contact structure, coordination between main contact and arcing one, et al on the electric field between contacts are discussed. 在此基础上分别对喷口,最大开距,主触头结构,主、弧触头间结构的配合等参数的改变对断口间电场的影响,进行了讨论。
