防爆特殊型电源装置的防爆原理是:它不采用或依靠隔爆外壳,而是在蓄电池本身和蓄电池箱内采取附加的特殊措施,使电源装置内部在正常和故障时不发生电弧或电火花,消除点火源,并防止箱体内氢气的积聚,以达到防爆的目的。而防止蓄电池极柱之间以及极柱对地的漏电故障是保证电源装置内部在正常和故障情况下不产生电火花或电弧的重要措施之一。
Explosion-proof special type power supply device explosion-proof principle is: it does not rely on or rely on flameproof enclosure, but in the battery itself and the battery box to take additional special measures to make the power supply device within the normal and fault does not occur arc or spark, Eliminate the ignition source, and prevent the accumulation of hydrogen in the box, in order to achieve the purpose of explosion. And to prevent leakage between the battery poles and pole to ground leakage fault is to ensure that the power supply device within the normal and fault conditions, one of the important measures do not produce sparks or arcing.
