摘　　要：阀控式铅酸蓄电池因其结构简单、价格低廉、内阻较小以及启动性能好的优点,广泛应用于变电站直流系统.但是,铅酸蓄电池在工作过程中因使用不当或其他因素存在不同程度的硫化问题,有的甚至使用不久就无法进行充电.针对这种情况,设计了一台修复受损铅酸电池的脉冲除硫恢复装置,通过其产生的正负高频脉冲击打硫化结晶体,使其重新回归到电解液中,从而延长铅酸蓄电池的使用寿命.Valve-regulated lead-acid batteries are widely used in substation DC systems because of their advantages of simple structure,low price,low internal resistance and good starting performance.However,due to improper use or other factors,lead-acid batteries have different degrees of vulcanization problems,and some cannot even be charged soon after use.In view of this situation,a pulse desulfurization recovery device for repairing damaged lead-acid batteries was designed.The positive and negative high-frequency pulses generated by it hit the sulfide crystals to make them return to the electrolyte and extend the lead-acid battery Service life.
