石墨
的电接触性能比不上铜甚至铝的……铜
石墨
复合材料不知道性能咋样不过讲真,没必要搞那么复杂……本来只是一个简单的轨道炮,结果谈到后面连2kA的可控硅都出来了……能动就行的话,,弹丸弄一小条铜片弯个U形就好了嘛,还自带预紧力呢😂大电流滑动接触铜优于铜
石墨
没问题,但是那是在接触面充分紧密的情况下得出的结论,轨道炮这种接触很明前不那么紧密嘛就不好说了既然接触性能都不是特别优越,,所以我就退而求其次保证轨道使用次数呗因为大家做轨道炮基本上就是让主轨直接接触电枢,并没有可以承受烧灼的缓冲结构,这导致只要出现烧灼清则打磨,重则换轨,况且很多爱好者做的轨道炮轨道并不是那么好换……而且本来尝试铜
石墨
轨道并不是因为它接触电阻多低,不就是把铜换成铜
石墨
,空气开关换成了可控硅嘛,这完全就是在原有基础上对材料做了替换嘛,当然了,这比原先的配置多了一个可控硅触发电路,如果你认为这也叫“复杂”的话……😂至于电枢,我个人认为不到一定规模(
