在1450V时连接铜管产生闪烁。作者: liuyouqing 时间: 2011-5-23 19:02
铜管材质有问题,弹性不好。作者: liuyouqing 时间: 2011-5-26 15:44
有没有高手还有不同看法?作者: gangzi 时间: 2011-5-27 08:43
这么多天了没有高手出来呀,自己发表,呵呵 - T9 Q$ K1 b& H- e4 f8 n我请教了高手,可能是两个原因,一是材料,二是模具(制作工艺)作者: liuyouqing 时间: 2011-5-27 14:42
成型压力和内架也有关系,关键要看内架是不是已经变形。作者: billma 时间: 2021-1-17 10:32
铜套弹性太小,摩擦掉太多铜削,电测闪络。
