摘要
分析了常熟水利枢纽直流装置系统在运行中存在的问题及发生故障的原因,介绍了GZDW-B系列程控直流装置的设备构成、高频开关电源模块的特点和功能,以及蓄电池组的充放电特性。阐述了该装置交直流回路、检测和控制回路、报警回路、充放回路以及对蓄电池组的控制、保护、测量回路的工作原理。采用该装置进行技术改造,泵站运行情况良好。
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.
