摘　　要：通过对变电所直流盘的充电不良率较高的原因进行分析和总结,明确变电所直流盘充电率较低的主要原因,并依据要因制定了针对性的应对措施。经实际运行产生了良好的应用效果,统计发现各变电所直流盘的充电不良率由6%降到2%以内,为全厂各生产装置提供了优质的供电网络。By analyzing and summarizing the reasons for the high charging failure rate of the DC panel in the substation,the main reasons for the low charging rate of the DC panel in the substation are identified,and targeted response measures are formulated based on the main factors.After practical operation,good application results have been achieved.Statistics show that the charging failure rate of DC panels in each substation has decreased from 6%to less than 2%,providing high-quality power supply network for all production devices in the entire factory.
