Abstract Based on the analysis of the present problems and the cause of accidents, the setup of GZDW-Bseries program-controlled DC devices and the characteristics and functions of modules of high frequencyswitch power supply as well as the charging and discharging properties of storage battery cells are introduced.The control, protection and measurement function of the GZDW-B series DC devices to the battery cells, andthe principles of DC or AC electric circuits, alarming, charging and discharging circuits of the new type DCdevices are also presented. The performance of the pumping station is very well after the technical improvement.
