A pulse magnetic shock catapult comprises a power supply, a power supply control panel, a U-shaped catapult guide rail connected with the power supply control panel and a catapult tractor arranged onthe U-shaped catapult guide rail in a sliding connection mode, the catapult tractor is a sliding block of a frame structure, and at least four pairs of magnets which are symmetrically arranged up anddown and have alternate positive and negative magnetic poles are embedded in the sliding block; silicon steel sheet winding unit arrays formed by connecting windings in series in the length directionare symmetrically embedded in the left side wall and the right side wall of the U-shaped catapult guide rail; each silicon steel sheet winding unit comprises two oppositely-arranged coils, the power supply supplies power to the silicon steel sheet winding unit to generate a magnetic field, and the power supply is a super-power variable-frequency pulse generator. The catapult is simple in structure, low in technical difficulty, low in manufacturing cost, convenient to maintain and remarkable in energy conservation. Under the same condition, compared with an existing electromagnetic catapult using a permanent magnet linear synchronous motor, energy is saved by at least 40%. Power is supplied in a ground-wire-free mode, the pulse amplitude can be reduced, the consumption of an electric brushis reduced, and a ground wire is omitted.
一种脉冲磁震弹射器,包括电源、供电控制板、与供电控制板连接的U型弹射导轨以及设置在U型弹射导轨上滑动连接的弹射牵引器,弹射牵引器是框架结构滑块,滑块内嵌有至少四对上下两块对称配置的正负磁极相间的磁铁;U型弹射导轨的左右两侧壁对称嵌装有绕组沿长度方向串联连接构成的矽钢片绕组单元阵列;矽钢片绕组单元包括两个相向配置的线圈,矽钢片绕组单元由电源供电产生磁场,电源是超大功率变频脉冲发生器。本发明结构简单,技术难度小,制作成本低,维护方便,节能显著。同等条件下与现有使用永磁直线同步电机的电磁弹射器对比,节能至少40%。本发明采用无地线方式供电不仅可以降低脉冲幅度,降低电刷消耗量,而且省去了地线。
