G*DAPS4-BU充电仪的研制

Development of G*DAPS4-BU Charger.

针对G DAPS 4数字地震仪充电机存在的问题 ,研制成功G DAPS4 BU充电仪。通过开关电源和逻辑控制电路 ,采用脉冲方式进行充电 ,并设计了充放电自动转换装置 ,解决了恒流充电的实际问题 ,消除了“记忆效应”的不良影响。充电性能与原充电机相同 ,同时具有结构简单、合理 ,降低了生产成本 ,解决了生产难题 。

According to existential problems of the charger of G*DAPS 4 seismic instrument, G*DAPS4 BU charger is developed.Through medium of the on/off power and logic control circuit,it charges battery by the pluse mode.Being designed with the autochange unit for charging and discharging,G*DAPS4 BU charger can slove the problem of charging with constant current and eliminate the bad effect of “memory”.Its incharge performance is same as the old charger.It has advatages over the old charger at production cost and charging period,and it has simple and logical structrue.
