具有状态识别特征的引信用电磁拔销器

电磁拔销器可利用得失电原理实现引信的安全状态可恢复功能。为了使引信或安保机构能够简便获得电磁拔销器已完成解保程序或已恢复安全状态的信息,提出具有状态识别特征的引信用电磁拔销器,在目前使用的电磁拔销器结构的基础上增加了触发部件和信号输出部件,将其工作过程同步为信号输出部件通断的过程,使引信或安保机构通过信号采集就可获得安全状态信息。结果表明:该电磁拔销器工作状态稳定,信号输出可靠,最小响应时间为3 ms。

A New Electromagnetic Actuator with State Signal Output Function Module

The state of routine electromagnetic actuator is invisible for the safety and guarantees organization of fuze control system, thus it is difficult to control, manage, or improve of security unit. Accounting for this problem, a new electromagnetic solenoid with character of state recognition is designed, with both triggering unit and signal feedback component added. The working principle is that, when triggering unit invokes the signal feedback component, the signal line is close-up, and state signal is outputted to indicate that the locked state is rescind; otherwise, the securing pin is locked. The test results show that, the output function of this new electromagnetic solenoid is reliable and robust, with a best-case response time of 3ms.
