1 前言 东风4 型机车原采用ＮＧ4 62蓄电池 ,这是一种正极为管式结构的开口式蓄电池 ,这种电池有一个缺点 ,就是耗水量大 ,酸腐蚀严重。采用阀控式密闭电池后 ,这个缺点得到根本解决。特别是由于正极采用涂膏式极板 ,使正极板中心距减少了 5ｍｍ左右 ,所以电池的内阻减少了
1 Introduction Dongfeng 4 locomotive originally used NG462 battery, which is a positive tubular structure of the open-type battery, this battery has one drawback is that water consumption, acid corrosion is serious. The use of valve-controlled sealed battery, this shortcoming has been fundamentally resolved. Especially since the positive electrode is coated with paste plate, the center of the positive plate is reduced by about 5mm, so the battery’s internal resistance is reduced
