　　中國低壓空氣斷路器與世界先進水平相比
，除了在研發設計上的不足外，在製造工藝及檢測設備上也有較大差距。

　　在製造工藝上，例如銀合金觸點的焊接，達不到被焊的銅觸片不燒紅、銅觸片不被退火而維護原有硬度的要求

　　在檢測方麵，特別是在企業出廠檢測上，尚有不少指標是不符合國家標準及IECbiaozhunde，qicanshutiaozhengyunchayejiaoda，congershibushaochanpinzaiyonghuchufashengbugaidongzuoerwudongdebuzhengchangxianxiang。liruduanlutuokouqitiaozhengdongzuozhishi，anbiaozhunguidingyingtongguowufeizhouqifenliangdezhengxianbodianliu
