| Popis: | In order to study the effect of series initiation and parallel initiation on multi-point synchronous initiation of EFI (Exploding Foil Initiator, EFI), two-point series and two-point parallel electric explosion, three-point series and three-point parallel electric explosion of exploding foil were tested in this paper. The electrical explosion parameters for synchronous initiation of exploding foil two-point in series and two-point in parallel were tested also. The electric explosion parameters of exploding foil varies with the initiation voltage were analyzed. The effects of series initiation and parallel initiation on the performance of exploding foil multi-point synchronous initiation were obtained. The initiation sensitivity test of three-point series EFI and four-point hybrid EFI was carried out. The experimental results agree well with the analysis law. The research results show that series initiation is beneficial to improve the consistency of initiation conditions at each point on the condition of exploding foil multi-point initiation, is beneficial to improve the synchronization of multi-point initiation. But it’s adverse to the full release of system energy when the number of series initiation points is large. Parallel initiation is beneficial to improve the system energy utilization. But the explosion synchronization relatively poor when system energy is low. The explosion synchronization of exploding foil will be better when system energy increase. It’s benefits to increase the consistency of initiation conditions at each point of exploding foil, benefit to increase the system energy utilization and reduce system firing energy that adopt reasonable combination of series and parallel, when the number of initiation point is large and system energy is sufficient. |
