VRLA电池作为核电厂1E级蓄电池可行性探讨

Feasibility discussion of VRLA batteries as class 1E batteries for nuclear power plant

核电厂采用1E级蓄电池为富液式铅酸蓄电池,而富液式蓄电池无法同时满足三代非能动核电站大电流和长时间放电性能要求。通过富液式铅酸蓄电池和阀控式铅酸蓄电池性能对比,结合核电厂1E级蓄电池的使用工况,从电池综合性能及安全性角度探讨了阀控式铅酸蓄电池作为核电厂1E级蓄电池可行性。

Now class 1E batteries for the nuclear power plants are flooded lead acid batteries.But the flooded lead acid batteries couldn't satisfy the large current and the long time discharge performance demand of the three generation passive nuclear power plants.Based on the comparison of the flooded lead acid batteries and valve regulated lead acid(VRLA)batteries,and combined with the working conditions of class 1E batteries for nuclear power plants,the feasibility of VRLA batteries as the class 1E batteries for the nuclear power plant were discussed from the battery aspect of comprehensive performance and security.
