自从1928年开始使用狭缝式防爆蓄电池机车以来,实践证明这种类型的电机车还不能在所有使用场合都满足生产和安全的需要,使用范围比较狭窄。为此,有关的商业部门和经营蓄电池的厂家对防爆蓄电池都开展了研究。
Since the beginning of the use of slot-type explosion-proof battery locomotives in 1928, it has been proved that this type of electric locomotive can not meet production and safety needs in all applications and has a narrow application range. To this end, the relevant commercial departments and manufacturers of batteries have carried out research on explosion-proof batteries.
